1238 PM CDT Fri Mar 22 2024 - A strong cold front moves through the area today with gusty north winds and colder temperatures behind it. - Sub-freezing temperatures for overnight lows tonight/ Saturday morning.
After this main rain area moves east, we will be looking at a less widespread nature to the rainfall, as isolated to scattered showers will then continue at times across our area through tonight and possibly even into early Saturday morning as the upper level trough moves east across the region.
207 PM EDT Fri Mar 22 2024 Moisture will overspread the region tonight as a low pressure system approaches from the Deep South. Widespread showers and a few thunderstorms are expected tonight, becoming scattered Saturday as the upper low moves over the area.
312 PM EDT Fri Mar 22 2024 Moderate to occasionally heavy rain tonight into early Saturday will precede a cold front.
A backdoor Canadian cold front will remain stalled in northwest Montana along the Continental Divide. This feature could allow for slightly higher accumulations, mainly along the Highway 2 corridor from Essex eastward to Marias Pass. Mountain passes area wide will likely see some snow cover, especially along the cold frontal boundary as it passes late morning into early afternoon.
Partly cloudy today underneath a weakening upper level ridge. This is response to an approaching upper level low expected to bring precipitation on Saturday. Have added low pops across the higher terrain of south-central Idaho this afternoon to account for this shift. Otherwise, the forecast remains on track with precipitation on Saturday with the cold frontal passage. Widespread rain/snow Saturday morning and obscured mountains as a cold front moves in.
The current KBYX VAD wind profile continues to verify a great veering profile behind the warm front that lifted north through the Keys earlier this morning. From synopsis, strong east to southeast breezes will continue today across the coastal waters of the Florida Keys as low pressure develops in the Gulf of Mexico.
204 PM EDT Fri Mar 22 2024 A low pressure and a cold front bring chances of rain through Saturday.
A mix of freezing rain/sleet may occur over south central South Dakota late Saturday night.
1213 PM CDT Fri Mar 22 2024 (The rest of today ) Showers continue across southeast Oklahoma into western Arkansas this morning as an upper level low spins across northeast Texas. This activity is forecast to end from the northwest to southeast this afternoon as the upper level feature shifts east into the Lower Mississippi Valley. Right on the heels of the upper level low, a surface cold front currently moving into southeast Kansas will surge through much of eastern Oklahoma and western Arkansas.
1250 PM CDT Fri Mar 22 2024 (Today and tonight) Weak ridging will be in place following the low pressure system that has now moved off to the east. This will result in a lack of rain chances and slightly warmer conditions across the region for this afternoon.
252 PM CDT Fri Mar 22 2024 - Cooler Saturday with morning lows in the 20s and highs in the 40s and 50s.
1229 PM CDT Fri Mar 22 2024 (Today through Saturday) Closed 500 mb low pressure currently over east Texas will gradually shift into the Atlantic Seaboard during the period, leaving the BRO CWFA in a nearly zonal mid-level flow.
We are ending this week on a soggy and cloudy note due to a low pressure system that continues to spin in the Gulf of Mexico.
The majority of the precipitation was ongoing along and north of a warm front draped across the central part of the state. A cold front will move into the region Saturday and push through the region by Saturday evening. Thus our high temperature forecast for Saturday ranges from the low 60s in northwest Georgia to the lower 70s in east central Georgia.
These showers were forming north and east of a developing area of low pressure over the AR-LA-MS region. With the area of low pressure traversing the Deep South tonight, have maintained high rain chances of 80-100%.
200 PM EDT Fri Mar 22 2024 A cool easterly flow will wedge against the eastern slopes of the Blue Ridge tonight, while an area of low pressure brings rain for the Mid Atlantic.
(This evening through Saturday) The upper low continues to head eastward out of east Texas, with drier air filtering in across west central Texas behind a weak front. Overnight lows will stay near normal in the lower to mid 40s, with afternoon highs tomorrow much the same as today, in the 70s. Quiet weather and mostly clear skies through tomorrow with westerly flow aloft, before a lee trough strengthens over far west Texas.
154 PM CDT Fri Mar 22 2024 - Spotty showers will produce light rain or sprinkles of it, especially over the lower Ohio River Valley, until the low pressure system responsible shifts to the east tonight.
(Through tonight) Precipitation chances will continue to dwindle this evening as the upper level feature responsible continues to progress east- southeastward and the associated cold front advances through the area. Most locations will remain in the mid- upper 30s/ lower 40s tonight, though points near the OK- KS border may briefly fall to near freezing. As high pressure moves eastward late in the day Saturday, sfc winds will begin to turn out of the southeast.
(The rest of today ) Showers continue across southeast Oklahoma into western Arkansas this morning as an upper level low spins across northeast Texas. This activity is forecast to end from the northwest to southeast this afternoon as the upper level feature shifts east into the Lower Mississippi Valley. Right on the heels of the upper level low, a surface cold front currently moving into southeast Kansas will surge through much of eastern Oklahoma and western Arkansas.
401 PM EDT Fri Mar 22 2024 A cold front will move through tonight.
158 PM EDT Fri Mar 22 2024 A low pressure system and associated frontal boundary will track through the Ohio Valley bringing rain to the region today into tonight.
1105 AM EDT Fri Mar 22 2024 A cool easterly flow will wedge against the eastern slopes of the Blue Ridge tonight, while an area of low pressure brings rain for the Mid Atlantic.
100 PM EDT Fri Mar 22 2024 A low pressure and a cold front bring chances of rain through Saturday.
159 PM CDT Fri Mar 22 2024 Tonight through Saturday: As the low pressure system migrates away from the area, showers will gradually come to an end. On Saturday, a mid-level ridge will build in from the southwest, advecting cooler and dry air into the CWA. The aforementioned ridge will also help any lingering clouds to dissipate, making way for clear skies toward the evening. Expect afternoon temperatures to range from the lower 60s to near 70 degrees.
748 PM CDT Fri Mar 22 2024 Low pressure moving across Alabama was creating widespread showers across the Tennessee Valley this evening. Passage of a cold front late tonight through early Saturday morning will bring increasing influence from dry high pressure out of Canada. A surface/upper trough is situated to our west, so look for deeper moisture to spread into Middle Tennessee during the next several hours. Drier, cooler air will work its way into the area tomorrow.
This slightly raised totals across the lower elevations across the southern half of the CWA (generally 0.
858 PM EDT Fri Mar 22 2024 Moisture will overspread the region tonight as a low pressure system approaches from the Deep South. Widespread showers and a few thunderstorms are expected tonight, becoming more scattered on Saturday as the upper low moves over the area.
Closer to sunrise, a cold front will approach the western FL peninsula with SW flow advecting richer moisture northward. The low-level wind profile across this area could remain weakly backed just long enough to support a rotating storm as activity races offshore by late morning and surface flow gradually veers SW.
747 PM CDT Fri Mar 22 2024 Tonight through Saturday: As the low pressure system migrates away from the area, showers will gradually come to an end. On Saturday, a mid-level ridge will build in from the southwest, advecting cooler and dry air into the CWA. The aforementioned ridge will also help any lingering clouds to dissipate, making way for clear skies toward the evening. Expect afternoon temperatures to range from the lower 60s to near 70 degrees.
This low will move southeastward tonight. This feature will also move eastward overnight dragging a cold front through early tomorrow. The higher res models are doing ok with this activity and show it lifting to the NE across the CWA overnight. The majority of the precipitation was ongoing along and north of a warm front draped across the central part of the state. A cold front will move into the region Saturday and push through the region by Saturday evening. Thus our high temperature forecast for Saturday ranges from the low 60s in northwest Georgia to the lower 70s in east central Georgia.
208 PM PDT Fri Mar 22 2024 Periods of widespread rain, heavy mountain snow, breezy winds, and cooler weather return through the weekend with the current storm system.
515 PM EDT Fri Mar 22 2024 A low pressure and a cold front bring chances of rain through Saturday.
659 PM CDT Fri Mar 22 2024 (This evening through Saturday) The upper low continues to head eastward out of east Texas, with drier air filtering in across west central Texas behind a weak front. Overnight lows will stay near normal in the lower to mid 40s, with afternoon highs tomorrow much the same as today, in the 70s. Quiet weather and mostly clear skies through tomorrow with westerly flow aloft, before a lee trough strengthens over far west Texas.
A system will bring a mix of snow, rain, sleet, and freezing rain across Central NY and NE PA this evening into Saturday morning. The best chances for freezing rain will be concentrated in the Catskills and north up to Otsego County, with a secondary area over the Finger Lakes region, reaching from Steuben up to Seneca counties in New York. The higher amounts of closer to 2 inches of total precipitation is most likely in the Catskills and east of the Scranton-Wilkes Barre area.
An upper low offshore will slowly move eastward and move inland later Saturday bringing periods of rain.
624 PM CDT Fri Mar 22 2024 - Spotty showers will produce light rain or sprinkles of it, especially over the lower Ohio River Valley, until the low pressure system responsible shifts to the east tonight.
917 PM EDT Fri Mar 22 2024 A cold front will move through tonight.
740 PM EDT Fri Mar 22 2024 A low pressure and a cold front bring chances of rain through Saturday.
533 PM CDT Fri Mar 22 2024 Ongoing showers will eventually taper as a cold front moves through the region later tonight.
855 PM EDT Fri Mar 22 2024 - A low pressure system passing to our south and a disturbance approaching from the northwest will bring rain tonight.
750 PM EDT Fri Mar 22 2024 A cold front will move through tonight.
642 PM CDT Fri Mar 22 2024 - Cooler Saturday with morning lows in the 20s and highs in the 40s and 50s.
634 PM CDT Fri Mar 22 2024 (Through tonight) Precipitation chances will continue to dwindle this evening as the upper level feature responsible continues to progress east- southeastward and the associated cold front advances through the area. Most locations will remain in the mid- upper 30s/ lower 40s tonight, though points near the OK- KS border may briefly fall to near freezing. As high pressure moves eastward late in the day Saturday, sfc winds will begin to turn out of the southeast.
Despite the downward trend in this most recent activity, water vapor satellite imagery still shows an impressive upper level low draped across the north Gulf Coast. Despite that, all solutions show winds picking back up as the upper level low continues to shift east overnight and into Saturday.
- Starting early Sunday morning and lasting into the evening, a cold front will bring strong and gusty north winds to the Bighorn Basin, Johnson County, and locations along Muddy & Cottonwood Creeks west of Boysen Reservoir in northern Fremont County.
1224 AM CDT Sat Mar 23 2024 - Cooler Saturday with morning lows in the 20s and highs in the 40s and 50s.
101 AM CDT Sat Mar 23 2024 Ongoing showers will eventually taper as a cold front moves through the region later tonight.
314 AM CDT Sat Mar 23 2024 - Sub freezing temperatures this morning across the regions.
Satellite imagery shows upper level low off the Central Oregon Coast near 43N/127W, a little further east than the models position. Showers rotating around the low over Western Washington this evening. Doppler radar showing enhanced echoes near the coast but with the low further east the flow aloft over Western Washington is southerly so these showers should stay along the coast and offshore. An upper low offshore will slowly move eastward and move inland later Saturday bringing periods of rain. A weak, brief upper ridge offshore on Sunday.
* Temperatures below freezing for northern portions of the region Sunday morning. A cold front is draped NE to SW through KY this evening. Low-level moisture is gradually being drawn northward into the boundary from TN as the column saturates just downstream of the upper level trough. The weather then turns cool and breezy Saturday morning in the wake of the cold front. An upper trough and surface cold front will interact with slightly elevated precipitable water showing up on nearly saturated tropospheric soundings to result in widespread light rain tonight, mostly south of the Ohio River.
This increased cloud cover will keep temperatures on Sunday slightly cooler than today, though mainly eastern areas.
1123 PM CDT Fri Mar 22 2024 - Spotty showers will produce light rain or sprinkles of it, especially over the lower Ohio River Valley, until the low pressure system responsible shifts to the east tonight.
129 AM EDT Sat Mar 23 2024 A low pressure and a cold front bring chances of rain through Saturday.
Mountain passes area wide will likely see some snow cover, especially along the cold frontal boundary as it passes late morning into early afternoon. Tonight into Sunday, the Canadian cold front which has been banked up along the Continental Divide will begin to cross into western Montana and north central Idaho. Another concern with this Canadian cold front will be for a rapid freeze-up situation on the roadways. Ensemble guidance still shows the potential for a closed low to develop (70 percent chance) across southwest Montana into Sunday morning, which would further focus snowfall. For north central Idaho, cooler temperatures will be noticeable. However, snowfall will mainly be limited to the higher terrain with lower valleys seeing little to no accumulations. The higher elevations have a higher chance for experiencing snow and ice on the roads.
An intensifying surface pressure gradient will occur on Sunday along the Lower Texas Coast and the western Gulf of Mexico.
The ridge of high pressure will continue to migrate eastward as a low pressure system pushes into the Pacific Northwest overnight. Conditions Saturday night look to deteriorate even more as the low pressure's cold front pushes through Arizona through Sunday morning.
1230 AM CDT Sat Mar 23 2024 (This evening through Saturday) The upper low continues to head eastward out of east Texas, with drier air filtering in across west central Texas behind a weak front. Overnight lows will stay near normal in the lower to mid 40s, with afternoon highs tomorrow much the same as today, in the 70s. Quiet weather and mostly clear skies through tomorrow with westerly flow aloft, before a lee trough strengthens over far west Texas.
Northerly flow behind the surface cold front will bring cooler, drier air to the region later this afternoon and into tonight. A clearing sky and cold, dry airmass will bring a return of cold temperatures tonight with some areas near or below freezing. This will limit frost in areas that have surface temperatures near or just above freezing; however, some sheltered valleys could see localized calm winds that result in frost formation.
236 AM EDT Sat Mar 23 2024 A cold front will move through tonight.
157 AM PDT Sat Mar 23 2024 Periods of widespread rain, heavy mountain snow, breezy winds, and cooler weather continues today with the current storm system.
(Today through Sunday Night) A cold front is moving SE through central into SERN sections of the CWA early this Sat morning. The NRLY winds will decrease also by this afternoon/evening as high pressure moves closer to the state. Dry and quiet conditions will be seen for tonight into Sun as the high pressure moves over the region.
This due to surface ridging influences from our north building in behind surface cold frontal passage that will push southeast of our area by sunrise today with upper levels taking on more ridging characteristics as tonight through at least the Sunday morning hours progress. Lows tonight are expected to bottom out in low to mid 30s, and maybe even slightly below freezing around 30 degrees Upper Cumberland Region. As surface ridging influences shift more eastward and southwesterly upper level flow begins to develop as Sunday afternoon hours progress, look for high temperatures on Sunday to warm back to once again seasonally warm values, mid to upper 60s, lower 60s higher elevations of Cumberland Plateau Region.
248 AM CDT Sat Mar 23 2024 - Today will be much cooler, with highs only in the lower to middle 50s, and breezy conditions this morning will make it feel even cooler.
1239 AM CDT Sat Mar 23 2024 Low pressure moving across Alabama was creating widespread showers across the Tennessee Valley this evening. Passage of a cold front late tonight through early Saturday morning will bring increasing influence from dry high pressure out of Canada. A surface/upper trough is situated to our west, so look for deeper moisture to spread into Middle Tennessee during the next several hours. Drier, cooler air will work its way into the area tomorrow.
337 AM EDT Sat Mar 23 2024 - A low pressure system passing to our south and a disturbance approaching from the northwest will bring rain this morning. - Widespread freezing temperatures are forecast for tonight into Sunday morning.
(Today and tonight) With the low pressure system well off to the east now, we will largely be under westerly flow aloft today.
In terms of winds, the highest marine platform registered 43 mph or 37 knots at both the Alligator Reef Light Weatherflow Mesonet and the Sand Key C-MAN. Meanwhile, Key West Airport reported the highest wind gust on land with a speed of 44 mph. An upper level low centered across AL & GA is quickly moving eastward this morning. The main period of concern will be this morning through the early afternoon before the upper level low pushes into the southwestern North Atlantic. By Sunday, drier air will return as the next high pressure quickly moves eastward across the U.
701 AM CDT Sat Mar 23 2024 - Today will be much cooler, with highs only in the lower to middle 50s, and breezy conditions this morning will make it feel even cooler.
This will gradually taper off over the next few hours as sfc front to the northwest swings in, helping dry out moist profiles aloft & eventually scour out the low-level moisture/clouds into the aftn hours. Highs will be seasonably cool, some 3-5 degrees below normal, in the low 60s northwest to near 70 degrees in the Pine Belt.
Cold front continues to progress thru the forecast area today with the best chance of accumulating valley snow in White Pine County tonight.
(Rest of Today) As showers move eastward out of northern AL with a cold front, mostly clear skies follow and will remain in place throughout the day.
544 AM CDT Sat Mar 23 2024 (Today through Sunday Night) A cold front is moving SE through central into SERN sections of the CWA early this Sat morning. The NRLY winds will decrease also by this afternoon/evening as high pressure moves closer to the state. Dry and quiet conditions will be seen for tonight into Sun as the high pressure moves over the region.
206 AM PDT Sat Mar 23 2024 Periods of widespread rain, heavy mountain snow, breezy winds, and cooler weather continues today with the current storm system.
Latest surface analysis had the cold front southeast of our CWA. This will gradually taper off over the next few hours as sfc front to the northwest swings in, helping dry out moist profiles aloft & eventually scour out the low-level moisture/clouds into the aftn hours. Highs will be seasonably cool, some 3-5 degrees below normal, in the low 60s northwest to near 70 degrees in the Pine Belt.
609 AM CDT Sat Mar 23 2024 - Sub freezing temperatures this morning across the regions.
Moisture advection is initiating from the Pacific and Gulf of Mexico with a broad low pressure system developing over Colorado. In fact, up to a quarter of the latest GFS ensemble solutions keep Plentywood dry, giving the lowest confidence for impacts there while winds still gust up to 40 mph.
We may see a few flakes mixing in down to far western NV valley floors at the tail end of these showers as snow levels crash behind the cold front passage. LULL THIS MORNING-EARLY AFTERNOON: Mid-level water vapor imagery reveals an area of dry air entraining into the upper low behind this morning's cold front. This lull will allow southwesterly winds to increase again ahead of the second portion of this storm, peaking early this afternoon around 25-30 mph for valley locations and 60-70 mph along Sierra ridges. LOOKING AHEAD: Much cooler temperatures stick around behind this morning's cold front with temperatures 10 degrees below average today.
625 AM CDT Sat Mar 23 2024 (Today and tonight) With the low pressure system well off to the east now, we will largely be under westerly flow aloft today.
A prefrontal trough is nearly stalled across the Florida Keys and has been the focus for linear clusters of thunderstorms throughout the morning. Surface observations and satellite imagery highlight a cold front diving southeast through the Gulf. The linear cluster north of the Lower Keys has steadily lost latitude over the past couple of hours, and should be the last hoorah for storms. Cooler, drier, less breezy, and sunnier skies are expected on Sunday.
1218 PM CDT Sat Mar 23 2024 (Rest of Today) As showers move eastward out of northern AL with a cold front, mostly clear skies follow and will remain in place throughout the day.
133 PM PDT Sat Mar 23 2024 Periods of rain, mountain snow, breezy winds, scattered thunderstorms and cooler weather continue through early Sunday. Temperature are trending approximately 10 to 15 degrees cooler than this time yesterday, valid at 130 PM PDT.
222 PM CDT Sat Mar 23 2024 Tonight and Sunday: Continued dry and cooler than normal through the period. Mid afternoon surface analysis had a 1030mb high centered over the northern Great Lakes region ridging south just west of our CWA.
With high pressure centered in the Upper Midwest extending southward into the region, dry easterly surface winds persist in most locations early this afternoon, although a shift to more southerly winds is expected through the evening and overnight as an upper level storm system approaches and low pressure organizes in the lee of the Rockies. This should lead to low temperatures that are noticeably warmer than those seen last night. There is some potential for similar gusts in the higher terrain areas of northwest Arkansas and possibly, southeast Oklahoma but will hold off on an advisory for now given lower confidence and likely, a later onset.
We expect to have our advisories expire as of 4 pm as the precipitation rapidly moves east and temperatures rise to a little above freezing in Sullivan county NY/Pike County PA. Plus road sensors are showing road surfaces above freezing at high elevations courtesy of the stronger late March sun. Any remaining precipitation quickly ends by early this evening, but with a tightening pressure gradient, gusty winds will develop, especially across the higher elevations of the Poconos- southern Catskills. High pressure moves into the area on Sunday which will result in mostly sunny skies and diminishing winds.
Diffluent flow aloft, advancing cold front, and weak instability across the northeast corner have already allowed for a couple isolated thunderstorms to form near Rexburg and further southwest near Atomic City.
