1150 AM CDT Fri Mar 15 2024 (Today and tonight) The current area of showers across north central and northeast Texas is expected to start shifting south early this morning as the cold front pushes south. With the front having moved through the forecast area, today's highs will be cooler than yesterday.
An Alberta Clipper moving through North Dakota will keep persistent breezy conditions along the border giving Carter and Fallon Counties the highest fire danger. The clipper will bring cooler temperatures into the east for Saturday increasing RH values and diminishing any fire threat. Today and tomorrow will remain dry as upper ridging makes its way in from the west. Temperatures will be in the 50s across most of the region today and tomorrow with cooler temperatures in the 40s for Carter and Fallon Counties tomorrow.
Daytime highs today will climb into the low-mid 60s, just a couple of degrees above seasonal average.
A pre-frontal trough is across central portions of GA. The pre-frontal trough is associated with a broken line of showers and thunderstorms that continues to move south. The high res models had a decent handle on the evolution of the line this morning, but may be struggling a bit with the current situation.
This activity formed along a pre-frontal trough axis that was ahead of the primary cold front with this storm system. The main cold front with this system currently stretches from central Kentucky southwest into western Tennessee and eastern Arkansas.
1254 PM EDT Fri Mar 15 2024 Scattered showers associated with a passing cold front will taper off this evening. High pressure will keep the upper Ohio valley dry for much of Saturday, before another cold front swings through the region bringing another round of rain Saturday night. ------------------------------------------------------------------- Cold front continues its trek to our south early this afternoon. Cold advection and cloud cover will be the contributing factors to temperatures, which should be much closer to seasonal values overnight - in the low to mid 30s. KEY MESSAGES: - High pressure will keep much of Saturday dry with diminishing cloud cover.
The deep mixing and a bit of a lower thickness lag behind the front also to help the 75th percentile high temp scenario and will go mid 50s north, to the low to mid 60s in the far southern CWA.
Cooler air will spill into the area but most of it will stay to our east as an upper trough digs south there and an upper ridge builds into the Northern Rockies.
Tonight and Saturday High pressure is in full control of the weather across eastern Idaho.
348 PM EDT Fri Mar 15 2024 Drier and cooler air will work into the area overnight into the Saturday as high pressure settles to the southwest in the wake of a cold front.
(This afternoon through Saturday night) WV imagery shows the upper trough stubbornly parked over the SoCal/Arizona border. Closer to home, surface analysis shows the cold front now working its way through the higher terrain. Saturday, temperatures should warm 3-4F over today's, more because of the absence of a cold front than anything else. Saturday night, the upper trough shows signs of finally moving east, w/models developing yet a third round of nocturnal convection. This would be highly unusual for these parts, but with the trough remaining west, not out of the question.
High pressure continues to dominate our weather pattern leading to dry and unseasonably warm weather. With the high pressure centered overhead, temperatures will approach 90 degrees for locations away from the coast this afternoon. The warm temperatures will continue this weekend, though with a cold front stalled just to our north and the increase in moisture with the southerly flow, additional cloud cover will limit the upward extent of our temperatures.
(This afternoon through Saturday) Strong ridging will remain over the region to wrap up the week and into the start of the weekend. At the surface, the large body of high pressure will continue to slowly drift eastward into the Atlantic Ocean. Highs today will climb into the lower 80s across the east coast metro areas and into the upper 80s across interior portions of Southwest Florida.
Tonight, low temperatures will be mild in the mid 60s area-wide after all of NE FL and SE GA reached the lower to mid 80s this afternoon.
207 PM EDT Fri Mar 15 2024 Drier and cooler air will work into the area overnight into the Saturday as high pressure settles to the southwest in the wake of a cold front.
113 PM EDT Fri Mar 15 2024 A cold front over northern PA will move south of the Keystone state this afternoon.
(Tonight through Saturday night) Showers and thunderstorms have developed near a cold front that is stretched across South Central Texas. An upper level low over the southwestern US will remain in place through the short term period.
A ridge of high pressure then builds in behind bringing drier conditions on Saturday with clearing skies.
413 PM EDT Fri Mar 15 2024 Low pressure will exit east of the Maritimes tonight through Saturday.
200 PM EDT Fri Mar 15 2024 Showers and drizzle continue along and ahead of a cold front through early this evening. Cooler and dry this weekend. A surface cold front continues to slowly work its way through the region from northwest to southeast through this evening. Ahead and along the cold front, patchy showers and perhaps an isolated rumble of thunder will be possible through the afternoon. Some patchy drizzle may briefly linger behind the cold front, but would not expect any additional measurable amounts.
206 PM EDT Fri Mar 15 2024 A cold front over central PA at mid afternoon will move south of the Keystone state by this evening.
This afternoon north of the boundary, temperatures will be a good 10 degrees cooler, with broken to overcast skies are expected to keep these temps in the mid to upper 60s. Plenty of low level moisture will keep overcast skies through the night, and temperatures in the low 50s across the north to the low 60s in the south. Saturday, high pressure will move across the southeast.
A cold front remains stretched from southwest to northeast and bisects the northern portions of our area. To the south of this boundary, a very warm, moist, and unstable air mass has developed with cloud breaks and heating resulting in temperatures are warming into the lower to middle 80s with dewpoints into the lower 70s. There still appears to be appreciable curvature in the lowest 3km so the threat for a tornado or two cannot be completely ruled out. The severe threat should be developing across areas west of I-65 and south of the cold front within the next one to three hours (2pm - 5pm), near the Mobile Metro areas between 4pm and 7pm, and portions of far south-central Alabama and the western Florida Panhandle from 6pm through 9pm.
1223 PM CDT Fri Mar 15 2024 -Temperature fluctuations are expected this forecast period with a few quick moving cold fronts impacting the region. Aloft, an H7 trough is moving over the central US and a large cutoff low remains over southern CA. Temperatures should top out about five degrees above mid-March averages today, in the low to mid 60s. A digging H5 trough over south-central Canada will advance through the Great Lakes region tomorrow, shunting a cold front through northeast KS during the afternoon. Post-frontal cold air advection will create a few cooler days as we wrap up the weekend and begin the next workweek.
314 PM EDT Fri Mar 15 2024 A high pressure ridge builds briefly into the area tonight and early Saturday. A strong cold front tracks through the region late Saturday evening into early Saturday night. This is all ahead of another cold front that will be dropping in from the northwest, associated with a closed upper level low tracking across northern Ontario. Expecting a line of showers with this cold front, no thunder, as it moves into the CWA after 21Z Saturday.
High pressure remains firmly entrenched over the Pacific Northwest and Northern Rockies, ensuring predominantly sunny skies with occasional high cloud cover.
- A cold front is forecast to move through the region this evening resulting in a wind shift.
129 PM EDT Fri Mar 15 2024 Scattered showers associated with a passing cold front will taper off this evening. High pressure will keep the upper Ohio valley dry for much of Saturday, before another cold front swings through the region bringing another round of rain Saturday night. ------------------------------------------------------------------- Cold front continues its trek to our south early this afternoon. Cold advection and cloud cover will be the contributing factors to temperatures, which should be much closer to seasonal values overnight - in the low to mid 30s. KEY MESSAGES: - High pressure will keep much of Saturday dry with diminishing cloud cover.
223 PM EDT Fri Mar 15 2024 A cold front will push south of the area this evening.
123 PM EDT Fri Mar 15 2024 Showers and drizzle continue along and ahead of a cold front through early this evening. Cooler and dry this weekend. A surface cold front continues to slowly work its way through the region from northwest to southeast through this evening. Ahead and along the cold front, patchy showers and perhaps an isolated rumble of thunder will be possible through the afternoon. Some patchy drizzle may briefly linger behind the cold front, but would not expect any additional measurable amounts.
1223 PM CDT Fri Mar 15 2024 (Today and tonight) Surface observations show the cold front continuing to push well south of our forecast area with gusty northwest winds expected overnight and for much of the day tomorrow before winds begin to subside in speed tonight. Thick overcast and persistent northwest winds will lead to much cooler temperatures today with highs in the 40s and 50s.
As high pressure settles southward tonight, clear skies and light winds should allow for decent radiational cooling although some mid and high clouds increasing from the SW may inhibit that to some degree.
and an upper-level trough across the Great Lakes region.
Mostly clear today with upper level ridge to the northwest and low to the southeast. Upper level low will be close enough today to allow for increased winds along the Nevada border and Western Magic Valley. Temperatures on track to reach the upper 50s to low 60s in the lower valleys. VFR under high pressure. VFR with dry and stable conditions as high pressure remains over the region.
640 PM CDT Fri Mar 15 2024 (This evening through Saturday night) Cooler temperatures and rain showers highlight the short term forecast. Cooler temperatures will remain across the Panhandles this afternoon along with scattered rain showers. A H500 low pressure system will remain fairly stationary near the southern tip of Nevada tonight through Saturday night.
A warming trend is in store through the weekend as high pressure builds into the area. This is due to a persistent closed low that is spinning over southwestern Arizona and far southern California. A ridge of high pressure remains over the Pacific Northwest states. These two systems have created a blocking pattern which will promote stagnant weather for the area. More clouds will be prevalent across portions of south- central Nevada due to the proximity of the closed upper low.
633 PM CDT Fri Mar 15 2024 (Tonight through Saturday night) Showers and thunderstorms have developed near a cold front that is stretched across South Central Texas. An upper level low over the southwestern US will remain in place through the short term period.
747 PM CDT Fri Mar 15 2024 Radar this evening shows a line of showers has developed along and near a cold front currently stretching from Pulaski to Crossville. Rest of forecast remains on track, with a colder airmass continuing to filter in behind the cold front across the midstate. Temperatures are now down into the low 50s in our northwest, and lows are expected to drop into the 40s areawide overnight.
711 PM EDT Fri Mar 15 2024 Drier and cooler air will work into the area overnight into the Saturday as high pressure settles to the southwest in the wake of a cold front.
523 PM EDT Fri Mar 15 2024 A cold front over central PA at mid afternoon will move south of the Keystone state by this evening.
705 PM EDT Fri Mar 15 2024 (This afternoon through Saturday) Strong ridging will remain over the region to wrap up the week and into the start of the weekend. At the surface, the large body of high pressure will continue to slowly drift eastward into the Atlantic Ocean. Highs today will climb into the lower 80s across the east coast metro areas and into the upper 80s across interior portions of Southwest Florida.
At the surface, a slow-moving cold front (and related band of light showers) will continue to push southeastward late this evening and should exit the forecast area by 6Z. Low temperatures were adjusted slightly to reflect light winds and the anticipated decrease in dewpoints, but actual values may end up being a degree or so warmer if low stratus clouds do not begin to scatter prior to sunrise.
A strong area of high pressure continues to amplify over the region, continuing the trend of warm and dry weather into the weekend. This high has brought gusty easterly winds over ridges and in Trinity and Lake Counties. The potential for record- breaking temperatures diminish into the weekend, as coastal temperatures cool slightly into the high 50s and low 60s. A coastal inverted trough will advance over the waters today.
High pressure will keep the area dry on Saturday. A cold front will bring another round of rain Saturday night.
629 PM CDT Fri Mar 15 2024 - A cold front will bring very strong winds to the Northland tonight into Saturday. - With this cold front a chance for rain and snow showers for much of the Northland tonight into Saturday, with a 40-60 percent chance of a tenth of an inch of precipitation along the international border, but elsewhere very low (<10%) odds for more than a tenth of an inch of precipitation.
Gusty winds continue to impact the area this afternoon, strongest over the higher terrain of the Sierra. As the winds subside by Saturday morning, the forecast turns to quiet, warm weather as ridging in the Pacific Northwest begins to dominate the forecast pattern.
1055 PM EDT Fri Mar 15 2024 Rain and drizzle in and near the mountains fade as a cold front pushes south overnight. High pressure Saturday. Next cold front brings a cold start to the new work week, with snow showers. Light rain and drizzle in and near the mountains continues to gradually fade, as the cold front pushes sluggishly through the far southern portion of the forecast area. A surface cold front continues to slowly work its way through the region from northwest to southeast through this evening. Ahead and along the cold front, patchy showers and perhaps an isolated rumble of thunder will be possible through the afternoon. Some patchy drizzle may briefly linger behind the cold front, but would not expect any additional measurable amounts.
452 PM CDT Fri Mar 15 2024 (This afternoon through Saturday night) WV imagery shows the upper trough stubbornly parked over the SoCal/Arizona border. Closer to home, surface analysis shows the cold front now working its way through the higher terrain. Saturday, temperatures should warm 3-4F over today's, more because of the absence of a cold front than anything else. Saturday night, the upper trough shows signs of finally moving east, w/models developing yet a third round of nocturnal convection. This would be highly unusual for these parts, but with the trough remaining west, not out of the question.
922 PM EDT Fri Mar 15 2024 A cold front will push south of the area this evening.
904 PM CDT Fri Mar 15 2024 Slightly cooler temperatures are beginning to filter into the Mid-South as a slow moving cold front pushes further into central Mississippi. Highs on Saturday will be a few degrees cooler: in the upper 60s to low 70s.
938 PM EDT Fri Mar 15 2024 Drier and cooler air will work into the area overnight into the Saturday as high pressure settles to the southwest in the wake of a cold front.
A few locations east of the I-65 corridor could still reach the lower 70s before sunset today. We still could have some isolated to scattered showers and maybe a thunderstorm or two along and ahead of the actual cold front before sunset. Not a big difference in temperatures ahead of and behind the cold front, but a difference none the less.
735 PM EDT Fri Mar 15 2024 After a cold front moves through the region tonight, dry conditions are expected Saturday between systems.
High pressure over the western Atlantic extending over Florida shifts southeastward ahead of a pair of cold fronts, the first of which forecast to sag into north Florida Saturday. Generally dry conditions continue as high pressure in the western Atlantic retreats southeastward ahead of a cold front sagging into north Florida.
643 PM EDT Fri Mar 15 2024 - Clearing tonight, warmer on Saturday.
That being said though, temperatures will be significantly cooler tonight in comparison to last night. Hourlies did need some slight adjustments in this update as most climate sites were about 2-3 deg F warmer than the current advertised forecast.
723 PM EDT Fri Mar 15 2024 A cold front over central PA at mid afternoon will move south of the Keystone state by this evening.
335 AM CDT Sat Mar 16 2024 Today and Tonight: Early morning surface analysis had a weak cold front just south of our CWA and a 1019mb centered over the Central Plains. In the wake of the cold front satellite imagery and surface observations showed plenty of stratus around 200ft with patchy fog. Despite the having the weak cold front through our CWA, temperatures will continue to top out warmer than normal today and will continue above normal tonight. /22/ Sunday morning, rain chances are expected to continue as a broad lower-level trough stretches into the Lower Mississippi Valley, bringing a cold frontal boundary into the region.
An strong upper level ridge continues to expand off the Pacific NW coast extending into SE AK and western BC.
Cold front appears to be drapped across the forecast area from near Victoria to near Laredo with the convection remaining mainly south of the boundary.
239 AM EDT Sat Mar 16 2024 High pressure takes control today. Weak cold front brings showers mainly across the northern portions of the area tonight. A cold front approaches from the northwest tonight, increasing clouds and chances for precipitation mainly across the northern portions of the Mid-Ohio valley and WV tonight. This will create strong gusty winds along the front and the higher elevations. However, confidence runs low whether wind gusts could reach advisory criteria over the higher ridges as only one model shows that outcome. Gusty winds can be expected with this front, particularly across the northern mountain zones where stronger winds aloft will have the potential to affect mountain peaks, with gusts 30 to 40 mph common, possibly approaching advisory criteria at times on the highest peaks.
1120 PM EDT Fri Mar 15 2024 Low pressure will exit east of the Maritimes tonight through Saturday. A warm front crosses the region Sunday.
133 AM MDT Sat Mar 16 2024 A strong upper ridge currently just off the Washington coast, will shift east into British Columbia and Washington through Sunday. Meanwhile a deep trough will deepen over the Great Lakes into Minnesota. A backdoor cold front has pushed into the eastern half of the state and that is the reason the east will be cooler compared to the rest of the area today. Cooler temperatures, northerly winds and clouds sweeping in from Canada, will provide higher humidity today, so fire weather concerns over the east will be less than yesterday. Central and eastern zones will have a glancing blow from the cooler air. The air will still limit highs to the lower to mid 50s, despite building mid level heights.
1244 AM CDT Sat Mar 16 2024 Slightly cooler temperatures are beginning to filter into the Mid-South as a slow moving cold front pushes further into central Mississippi. Highs on Saturday will be a few degrees cooler: in the upper 60s to low 70s. However, the northward extent of precipitation may end up being further south as a strong cold front dives across our area on Sunday as well. Much cooler conditions will start the work week with frost / freeze headlines likely needed.
1228 AM CDT Sat Mar 16 2024 (This afternoon through Saturday night) WV imagery shows the upper trough stubbornly parked over the SoCal/Arizona border. Closer to home, surface analysis shows the cold front now working its way through the higher terrain. Saturday, temperatures should warm 3-4F over today's, more because of the absence of a cold front than anything else. Saturday night, the upper trough shows signs of finally moving east, w/models developing yet a third round of nocturnal convection. This would be highly unusual for these parts, but with the trough remaining west, not out of the question.
- Temperatures bottom out Sunday with highs close to the freezing mark east river.
345 AM CDT Sat Mar 16 2024 -Seasonably warm today before a much cooler air mass moves into the area late this weekend. Prior to sunrise this morning, surface obs showed high pressure residing over KS. CAA will commence late today and continue through Sunday as a Canadian ridge travels south over the Northern High Plains. This pattern will cause temperatures to be about 15 degrees cooler tomorrow afternoon compared to today.
(Today and tonight) A cold front has cleared the area, leaving a N-NW flow pattern. A high pressure ridge will be over the area tonight, with another cold front approaching from the north.
Portions of Nrn AR are expected to see near freezing to sub-freezing temps on Mon mrng, w/ readings b/w 29-33F, primarily w/in the Nrn two rows of counties.
Area of light precip along the cold front has exited stage east and now have some upslope cold advection stratocu persisting in the mountains.
Otherwise, very mild conditions expected this afternoon with highs in the lower 70s in many locations.
Breezy at times with elevated fire weather conditions through Mon/Tue - Cooler with increasing chances for precipitation for the last half of the week Current surface map places deep low north of Lake Superior with cold front moving into northern South Dakota. Cold front moves through before daybreak, with cooler/breezy conditions today. Northwest flow aloft continues early this coming week with deep trough across Hudson Bay into the northeastern CONUS and riding across the Rockies.
Area of light precip along the cold front has exited stage east and now have some upslope cold advection stratocu persisting in the mountains. During this portion of the forecast, troughing across the US East Coast is expected to amplify.
1218 AM EDT Sat Mar 16 2024 (This afternoon through Saturday) Strong ridging will remain over the region to wrap up the week and into the start of the weekend. At the surface, the large body of high pressure will continue to slowly drift eastward into the Atlantic Ocean. Highs today will climb into the lower 80s across the east coast metro areas and into the upper 80s across interior portions of Southwest Florida.
1259 AM CDT Sat Mar 16 2024 (This evening through Saturday) Most of the showers and storms have moved east of the area this afternoon, with the cold front having swept south of the area. Otherwise, cooler conditions continue with lows in the 40s and 50s tonight, and rain and clouds keeping highs on Saturday in the 50s and 60s.
(Today through Sunday) To start the weekend, the area will be under the influence of a dominant high-pressure ridge. At the surface level, this extensive high-pressure zone will persistently move eastward toward the Atlantic Ocean. Mid-level ridging will subtlety weaken on Sunday, but overall dry and warm conditions will continue.
(Today through Sunday) Yesterday's cold front is now well past Middle Tennessee and high pressure is building in from the west. Temperatures will be cooler, and will be even colder after a (hopefully) dry cold front comes through early Sunday.
This will allow winds to calm and overnight lows to dip quite a bit cooler than the previous few nights, especially where clouds completely clear the area.
