604 AM CDT Sat May 11 2024 (Today and tonight) Increasing southeasterly surface flow bringing in Gulf moisture combined with a relatively deep upper trough will lead to widespread showers across the forecast area today.
348 AM MDT Sat May 11 2024 Warm and mostly dry conditions are expected through the weekend as upper level ridging remains over the area, with just a few light rain showers possible along the Hi Line tonight.
Conditions are quiet across the area this morning with NW flow and ridging aloft. Highs will be seasonal, in the low 80s and dewpoints comfortably in the 50s will make for a very pleasant day. As mid-level ridge builds eastward, isentropic ascent should decrease & clouds should thin. High temps will be seasonable in the low-mid 80s with decreased humidity. Seasonable lows, in the low 60s southeast of the Natchez Trace corridor to mid 60s to the northwest, are expected.
755 AM EDT Sat May 11 2024 Low pressure tracking from Michigan into western New York State is expected to bring showers and thunderstorms to the forecast area into tonight.
606 AM EDT Sat May 11 2024 High pressure builds across the region through Saturday night.
A ridge of high pressure will maintain dry conditions over the Pacific Northwest through much of the weekend. High pressure will allow for ample sunshine and a continuation of the warming trend, with daytime temperatures reaching 5 to 10 degrees above climatological norms today. Sunday will likely be our warmest day before the pattern change, with temps reaching into the mid to upper 70s for our low elevations, 60s in the highlands, and 50s in the high terrain. Winds will noticeably increase Sunday evening as the ridge begins to break down and upper flow turns more zonal ahead of an approaching trough.
508 AM MDT Sat May 11 2024 -Warmer and continued dry today.
624 AM EDT Sat May 11 2024 (Today and tonight) Cold front stretches this morning from the Florida panhandle to southern Georgia with dewpoints falling through the 60s to upper 50s north of the front with dewpoints remaining in the lower 70s south of this feature in the eastern Big Bend.
140 PM EDT Sat May 11 2024 Cooler weather for the weekend. Cold front exits east of the Appalachians early this evening.
(Today through Sunday) Models show a trough/low complex migrating east over the E CONUS, and sending an associated decaying cold front across the Florida peninsula. Expect widespread low-mid 90s this afternoon, with sea breezes maybe keeping immediate coastal areas a tad cooler. For Sunday, increasing cloud cover and northerly cooler flow should help in knocking down afternoon highs a few degrees.
1240 PM EDT Sat May 11 2024 Rain showers and scattered thunderstorms are likely through tonight with passage of a cold front.
We will see great weather for Mother's Day as high pressure builds over the area.
Temperature maximums will reach the lower 80s this afternoon with dewpoints at or below 60 degrees allowing for more pleasant outdoors conditions today. /16/ (Saturday through Sunday) Quiet weather should remain in place for most of this short-term, as upper-level ridging remains overhead. This will allow highs today to remain in the low to mid-80s, and lows tonight to range in the low to mid-60s.
253 PM EDT Sat May 11 2024 High pressure will build into the central Great Lakes and middle Ohio Valley tonight. The high will then push east across the region Sunday into Sunday night.
Additional showers and storms may develop through the remainder of the afternoon and evening, with the highest PoPs concentrated across the northwestern half of the area. (Sunday night through next Saturday) Expect a mainly dry and warmer forecast for early this week as upper 500 MB heights increase and our area is in the surface warm sector.
(Tonight through Sunday night) Weak upper level ridging over the Central Plains will help enhance southerly low-level flow through the period. The stationary boundary currently located over the area is expected to slowly shift north as a warm front, facilitating the return of hotter temperatures to the area. Low temperatures Sunday night are expected to be a bit warmer, staying in the upper 70s to low 80s. Warmer temperatures and a slight increase in humidity will allow heat index values to climb into triple digits, topping out a little below heat Advisory thresholds Sunday afternoon.
224 PM CDT Sat May 11 2024 - Sunday will end the weekend dry and warm with temperatures climbing into the low 80s for much of the area.
(This evening through Sunday) High pressure will move across the southern states today and tonight with prevailing northerly flow bringing cool and dry air to the state. By Sunday morning, the high will be weakening and moving east of the area with flow returning to out of the south and south west. Moisture and warmer air will will return to the state with high clouds increasing through late Sunday. Highs on Sunday are expected to be near normal and a couple of degrees warmer than today in the low 80s.
A weak front will drop south across the forecast area late tonight into early Sunday, reinforcing the slightly cooler and much drier airmass that is currently in place (at least through Sunday morning).
This upper-level trough will approach Texas this morning and eject multiple mid-level impulses over the region through the day. (Sunday night through next Saturday) Expect a mainly dry and warmer forecast for early this week as upper 500 MB heights increase and our area is in the surface warm sector.
Regarding showers/storms this afternoon-evening: A mid level wave moving to the north this evening/tonight will push a cold front into the region, and forcing will help lead to widely scattered showers and isolated thunderstorms through the evening mainly in northwest MN (some signal farther west in CAMs). For Sunday, the post frontal air mass should bring lower Tds in (along with cooler temps) but adjusting for biases, RH values are likely to once again drop to the 20-25% range.
142 PM EDT Sat May 11 2024 Cooler weather for the weekend. Cold front exits east of the Appalachians early this evening.
227 PM EDT Sat May 11 2024 A cold front will pass through the region this evening bringing another round of showers and isolated thunderstorms.
(Tonight) A very pleasant afternoon across the Tennessee Valley as high pressure keeps dry and mild conditions over the region. Low pressure to our northeast will continue to track toward the northern Atlantic Coast tonight, and a weak cold front will make its way into the area. Overnight lows will be on the cooler side, dropping into the lower 50s to upper 40s in the higher terrain.
High pressure is solidly in control of the weather pattern in the Northern Rockies currently. The warmest temperatures to date this year are expected today and tomorrow, with many warming to 80F or warmer by Sunday.
128 PM EDT Sat May 11 2024 Weak high pressure over the region late this morning will move offshore this evening. Low pressure centered over Lake Huron early this afternoon will move eastward through this evening into Sunday.
This is due to surface ridging that will weaken and shift eastward, re-introducing southerly winds and a chance of precipitation into Deep East Texas.
An upper level ridge over the area will allow clear skies to continue tonight with light winds.
1249 PM CDT Sat May 11 2024 (Rest of Today) High pressure will continue to reinforce a cooler and drier airmass over the region today, with mostly sunny skies and breezy westerly winds at times. After beginning the day in the low to mid 50s, temperatures have steadily warmed into the mid 60s this morning and are forecast to reach the mid to upper 70s this afternoon.
As high pressure moves east, we will slowly begin to recover a moist airmass with steady warm advection.
Seasonal temperatures with lighter winds midweek, along with slight chances of showers and thunderstorms over the high terrain in central New Mexico. Upper low over the Central Rockies reinforcing southwesterly flow will push this moisture off to the east and out of the local forecast area this evening, with a very weak return flow overnight. Temperatures will be a bit cooler, right near normal for mid-May with lowland highs in the mid 80s. The main weather concern going forward will be fire danger, but not expecting any headlines as winds decrease under a weak ridge aloft.
A ridge of high pressure will build over the region behind an upper low pulling away across the Four Corners.
210 PM CDT Sat May 11 2024 - Warmer this weekend with highs in the 80s on Sunday. Conditions stay dry and warmer through the weekend. We're in northwest flow aloft as an upper level trof moves through the Ohio Valley and towards the northeast. Our next system is an upper low and troughing that moves into the Plains by tomorrow night.
Satellite imagery shows an upper level low over northern Arizona that has brought in the continuous westerly flow across Southeast Arizona over the last several days. Luckily, the low will be moving out of our hair very soon. Near similar conditions expected tomorrow as the low moves to our east, but the winds will be more on the gusty side with pockets of locally breezy.
200 PM CDT Sat May 11 2024 - Warmer Sunday with afternoon-evening shower/storm chances (30- 50%).
1223 PM CDT Sat May 11 2024 (Today through Sunday Night) Dry conditions are expected across the state today as H500 NW flow will remain in place atop sfc ridging. Changes are expected on Sunday as the flow aloft will shift out of the SW ahead of a mid-level cyclone moving east across the Central/Southern Plains. At the sfc, ridging will begin to shift eastward which will allow low level flow will out of the S with dewpoints on the rise.
128 PM MDT Sat May 11 2024 High pressure remains in full control of the weather across eastern Idaho. Tomorrow will be even warmer for most locations with some spots in the Magic Valley potentially reaching 80. The break is right around 60 percent chance for a return to dry weather with an upper level high over the northwest coast, and a 40 percent chance of a continuance of west conditions with another trough. McKaughan A ridge of high pressure will bring drier and warmer conditions to East Idaho for the weekend.
Discussion: In the upper levels, northwesterly flow is in place with a ridge building into the region tomorrow. At the surface, a cold front is currently over Central Kentucky, starting to move into Middle Tennessee. Sunday will be dry with highs mainly in the 70s with high pressure over the Southeast.
1038 AM MDT Sat May 11 2024 -Warmer and continued dry today.
1136 AM MDT Sat May 11 2024 - Trending warmer through the weekend, but remaining unsettled with daily chances for showers and storms.
1246 PM CDT Sat May 11 2024 Conditions are quiet across the area this morning with NW flow and ridging aloft. Highs will be seasonal, in the low 80s and dewpoints comfortably in the 50s will make for a very pleasant day. As mid-level ridge builds eastward, isentropic ascent should decrease & clouds should thin. High temps will be seasonable in the low-mid 80s with decreased humidity. Seasonable lows, in the low 60s southeast of the Natchez Trace corridor to mid 60s to the northwest, are expected.
1101 AM EDT Sat May 11 2024 High pressure builds across the region through tonight.
1153 AM EDT Sat May 11 2024 High pressure builds across the region through tonight.
A few showers may develop across western Humboldt county Sunday with quiet weather conditions otherwise as high pressure builds across the region.
Early afternoon temperatures range from the lower to mid 60s across the NE mountains to the mid 70s across the S. A weak, reinforcing cold front will sweep into the N portion of the state this evening. High temperatures on Sunday will range from near 70 across the NE mountains to the lower 80s across the S third of the area.
Cold mid level temps associated with the incoming upper trough should steepen lapse rates enough to get some tall, skinny CAPE and actual thunderstorms for the mid afternoon through early eve time frame, and the uptick in forcing/ascent should help to increase the overall coverage. Perhaps the higher shear (30-35kt from 0-6km) could lead to a few cores with small hail, but this seems like worst case. It's a fairly slow moving upper trough with no real rush of dry air, so chances continue through Sun night (50-80%), and even into Mon AM (20-80%) - particularly for areas E and S of the Tri-Cities. This activity will be on the NW side of main mid/upper low, so severe weather remains unlikely.
1206 PM CDT Sat May 11 2024 (Today through Sunday) The upper ridging is now starting to drop into the NW CONUS and forcing the upper troughing over the west to begin moving SE and will eventually orient itself more meridionally. The flow over our area has become more zonal and as the upper trough gets a bit closer and orients N-S, it will cause a strong divergent area as it couples with the zonal flow to the south of it. The highest chances of rain should be over SW Miss and adjacent parishes of LA during the day.
322 PM EDT Sat May 11 2024 An upper level low will bring some rain showers to the region tonight into Sunday morning before gradually tapering off later in the day. Showers will continue through tonight as the core of the upper low crosses the region into Sunday morning. Lows will fall mainly into the 40s with some upper 30s across the higher elevations. The upper level low will begin to depart the region to the east with ongoing showers in the morning gradually tapering off during the afternoon and early evening hours.
Winds veer to the west and southwest Sunday with the passage of an upper trough to our north.
701 PM CDT Sat May 11 2024 (This evening through Sunday) High pressure will move across the southern states today and tonight with prevailing northerly flow bringing cool and dry air to the state. By Sunday morning, the high will be weakening and moving east of the area with flow returning to out of the south and south west. Moisture and warmer air will will return to the state with high clouds increasing through late Sunday. Highs on Sunday are expected to be near normal and a couple of degrees warmer than today in the low 80s.
631 PM CDT Sat May 11 2024 - Warmer Sunday with afternoon-evening shower/storm chances (30- 50%).
716 PM CDT Sat May 11 2024 - Warmer this weekend with highs in the 80s on Sunday. Conditions stay dry and warmer through the weekend. We're in northwest flow aloft as an upper level trof moves through the Ohio Valley and towards the northeast. Our next system is an upper low and troughing that moves into the Plains by tomorrow night.
621 PM CDT Sat May 11 2024 (Tonight) A very pleasant afternoon across the Tennessee Valley as high pressure keeps dry and mild conditions over the region. Low pressure to our northeast will continue to track toward the northern Atlantic Coast tonight, and a weak cold front will make its way into the area. Overnight lows will be on the cooler side, dropping into the lower 50s to upper 40s in the higher terrain.
The ridge of high pressure is weakening and this will allow coastal clouds to return tonight and Sunday night. Temperatures will be cooler and an inland shower or two is expected on Sunday.
601 PM EDT Sat May 11 2024 Rain showers and scattered thunderstorms are likely through tonight with passage of a cold front.
(The rest of tonight) High cloudiness will continue to stream overhead tonight across the region, downstream of an approaching mid level trough. Overnight lows will stay rather mild, mostly in the lower 60s, thanks to the increasing cloud cover.
813 PM EDT Sat May 11 2024 High pressure provides dry weather into the start of the new work week amid a warming trend.
Kept pops under 50 to reflect the lower chances for rain to reach the ground rather than evaporate despite numerous echos across NW Minnesota. Regarding showers/storms this afternoon-evening: A mid level wave moving to the north this evening/tonight will push a cold front into the region, and forcing will help lead to widely scattered showers and isolated thunderstorms through the evening mainly in northwest MN (some signal farther west in CAMs). For Sunday, the post frontal air mass should bring lower Tds in (along with cooler temps) but adjusting for biases, RH values are likely to once again drop to the 20-25% range.
503 PM EDT Sat May 11 2024 Cooler weather for the weekend. Cold front exits east of the Appalachians this evening.
802 PM EDT Sat May 11 2024 Rain showers and scattered thunderstorms are likely through tonight with passage of a cold front.
(Rest of tonight) A weak/dry cold front continues to move southeast into northern Alabama at this hour. Enough cloud cover and the lower dewpoints should keep fog from forming overnight, despite the light winds expected in the morning.
823 PM EDT Sat May 11 2024 Rain showers and scattered thunderstorms are likely through tonight with passage of a cold front.
939 PM EDT Sat May 11 2024 High pressure will build into the central Great Lakes and middle Ohio Valley tonight. The high will then push east across the region Sunday into Sunday night.
725 PM EDT Sat May 11 2024 High pressure will build into the central Great Lakes and middle Ohio Valley tonight. The high will then push east across the region Sunday into Sunday night.
High pressure will be centered over the area tonight with mainly clear skies and light winds. We will see great weather for Mother's Day as high pressure builds over the area.
Temperatures will run a few degrees warmer than last night for those heading outside to watch the night sky. An upper level ridge over the area will allow clear skies to continue tonight with light winds.
617 PM CDT Sat May 11 2024 - Sunday will end the weekend dry and warm with temperatures climbing into the low 80s for much of the area.
627 PM CDT Sat May 11 2024 (Tonight through Sunday night) Weak upper level ridging over the Central Plains will help enhance southerly low-level flow through the period. The stationary boundary currently located over the area is expected to slowly shift north as a warm front, facilitating the return of hotter temperatures to the area. Low temperatures Sunday night are expected to be a bit warmer, staying in the upper 70s to low 80s. Warmer temperatures and a slight increase in humidity will allow heat index values to climb into triple digits, topping out a little below heat Advisory thresholds Sunday afternoon.
244 PM PDT Sat May 11 2024 Temperatures through the weekend warm to the highest values of the season so far, with highs reaching the 80s and a few areas in the lower 90s.
An area of upper level ridging will pass across the region overnight, ahead of a closed area of low pressure slowly moving across the Four Corners Area. Meanwhile at the surface, high pressure will be moving east across the Lower MS Valley and TN Valleys, opening the local area up to southerly return flow. The lower levels remain rather dry, per 00z SHV and LCH soundings so do not expect a lot of precip to reach the surface. Lows will drop into the low to mid 60s for most locations. This is due to surface ridging that will weaken and shift eastward, re-introducing southerly winds and a chance of precipitation into Deep East Texas.
353 AM EDT Sun May 12 2024 High pressure over the area will move off to the east tonight and Monday.
131 AM EDT Sun May 12 2024 High pressure builds today with dry weather through Monday.
220 PM Update: Unsettled weather will continue through most of the period with just brief high pressure Sunday night into Monday morning. The low will fill and become vertically stacked overnight into Sunday as it moves over Central NY. This low moves east of the area by Sunday evening which will allow for showers to gradually taper off and should see some clearing in the clouds overnight into early Monday morning. 330PM Update Upper level low moves east of our region Monday morning with a brief ridge attempting to build in.
A cooler and more unsettled pattern will arrive for mid-week. An upper level ridge is building over the Pacific Northwest, resulting in a northwesterly flow aloft over Central Montana. Upper level ridging, with axis over the west coast, is slowly building eastward. With ridge axis off to the west, flow aloft is out of the northwest.
334 AM EDT Sun May 12 2024 High pressure builds today with dry weather through Monday.
1159 PM EDT Sat May 11 2024 A dry cold front will move offshore tonight, keeping the region cool and dry through Monday.
Otherwise, an upper low over the northeast CONUS this morning will shift eastward into the Atlantic by late this afternoon and early evening. Behind it, upper ridging will shift east from the Mississippi river valley towards the southern Appalachians.
(Today through Monday) Dry conditions will continue through early overnight hours tonight due to continued building of ridging influences surface and aloft. Afternoon high temperatures today will be around or slightly warmer than seasonal normal values ranging upper 70s to lower 80s, mid 70s Cumberland Plateau Region.
228 AM EDT Sun May 12 2024 High pressure provides dry weather into the start of the new work week amid a warming trend.
This boundary will move north today as a warm front, which will help set the stage for more widespread severe weather tomorrow, when the boundary reverses course as a cold front.
159 AM EDT Sun May 12 2024 High pressure will prevail into Monday. However, a slight uptick in winds and clouds is possible within a few hours prior to daybreak as a weak trough approaches the region. Highs peak in the low to mid 80s.
307 AM EDT Sun May 12 2024 High pressure remains across the region today, then exits across the Maritimes Monday.
150 AM EDT Sun May 12 2024 High pressure will build into the central Great Lakes and middle Ohio Valley tonight. The high will then push east across the region Sunday into Sunday night.
Expect an increase in mid and high clouds in advance of a mid level warm front that will lift into the area tonight, ahead of a trough moving across the Plains. Monday, upper level flow becomes southwesterly ahead of a trough moving across the Mid Mississippi River Valley. Ahead of the surface warm front, low level lift will result in more widespread rain showers and maybe a couple thunderstorms. The more widespread this activity is, the less likely the warm front is able to lift northward, curbing any strong storm potential.
The upper level ridge of high pressure that has produced these warm temperatures and clear skies will continue to sit over the region through tomorrow morning. Afternoon temperatures will decrease 4 to 7 degrees across the area as the ridge axis shifts east, but still expect mostly upper 70s to 80s in the lower elevations.
Issued 357 AM CDT Sun May 12 2024 Today through Monday: Light sly winds will develop early this morning becoming breezy swly winds this afternoon as a wave of low pressure moves across nrn WI. Low level warm advection will bring the thermal ridge into srn WI late in the day, and 925 mb temps will warm into the lower 20s Celsius. This will yield highs in the lower 80s for most locations. Just small chances (20-30 percent) for storms for the afternoon as the cold front remains well to the north, but the convective temp could be reached. The wave of low pressure will weaken tnt as it moves east, thereby slowing the arrival of the cold front until sunrise Mon for the nrn CWA.
1152 PM EDT Sat May 11 2024 A dry cold front will move offshore tonight, keeping the region cool and dry through Monday.
Early morning satellite imagery/RAP analysis showed our CWA downstream of a closed low spinning just east of the Four Corners region. Disturbances noted within the southern branch of the jet stream rounding the based of the closed low with help enhance convection as deep moisture increases back across our region. Local radars already showed some light showers moving east along the Highway 84 corridor as well as across southern Arkansas that will spread east along our Highway 82 corridor. Although the severe threat will likely wain with the loss of daytime heating, rain chances will continue through the night as the closed low shifts east to the southern Plains.
