Lows will bottom out in the lower 40s inland and the lower 50s along the coast. Northwesterly flow aloft will become zonal overnight and into Sunday morning as an amplified upper level ridge to our north slides across the Northern Plains and Midwest. Surface winds have already become more southwesterly this evening and should transition to southerly by Sunday morning as the high pressure pulls away from the local area. The slow moisture return and subsident pattern from the high pressure will keep rain chances at bay through Sunday night. Lows Sunday night range from the lower 50s inland to the lower 60s at the immediate coast.
A few spots may even get down around or below freezing by daybreak. Forecast highs this afternoon are expected to reach the lower 70s in northeast AL and mid 70s for northwest AL, which is near the climatological norms for this time of year. The clouds will keep overnight temperatures in the low to mid 50s.
350 AM EDT Sun Apr 10 2022 High pressure will bring dry conditions and rising temperatures through the middle of the week.
Expect full sun with comfortable temps and low humidity similar to Sat, but without the strong, gusty WNW winds as high pressure builds over the top of FL this afternoon. The high center will shift just offshore the peninsula by sunset, and then farther east over the adjacent Atlantic overnight. Max temps M-U70s inland, slightly cooler (L-M70s) near the coast, owing to earlier development of the ECSB.
Much warmer today, highs near seasonal averages, calmer winds and clear skies. This is as our longwave trough finally exits northeast and high pressure builds in behind it. No threat of frost or freeze tonight with lows in the low to upper 40s.
1219 AM CDT Sun Apr 10 2022 (This evening through Sunday) Warmer temperatures through the next 24 hours. The healthy southerly flow will also advect moisture into the area, helping to keep temperatures warm overnight, and lows are only expected to drop into the mid 50s to lower 60s, much warmer than the previous few nights when we were able to drop below freezing. There still may be a few isolated locations that are able to drop into the 40s, but most of the area will be much warmer.
1248 AM CDT Sun Apr 10 2022 For tonight, an upper level trough will approach the area. Temperature profiles will be able to support some snow from the panhandle up through the northwest sandhills with around an inch of accumulation near the Pine Ridge and lesser amounts further south and east. The upper trough axis will move across north central NE, with a continued chance for showers in the afternoon and evening.
400 AM CDT Sun Apr 10 2022 For tonight, an upper level trough will approach the area. Temperature profiles will be able to support some snow from the panhandle up through the northwest sandhills with around an inch of accumulation near the Pine Ridge and lesser amounts further south and east. The upper trough axis will move across north central NE, with a continued chance for showers in the afternoon and evening.
Much warmer weather can be expected this week. Lack of deep moisture and convective potential through the dendritic growth zone will preclude problematic snow accum, though a dusting on grassy surfaces, and up to an inch in the higher elevations remains plausible through dawn. Rain chances should return late Sunday night and Monday as the trough and associated sfc warm front cross the Upper Ohio Valley region. The aforementioned ridging should help gradually moderate temperature on Sunday, and by Monday support forecast temperature to average values or greater (PIT: 60F/38F).
341 AM EDT Sun Apr 10 2022 Dry and warmer weather expected today as a weak upper level ridge moves eastward through the region. 28 High pressure sets up in the Atlantic and mostly zonal flow will start off the week. Ridging remains in place for the first half of the week keeping most of the SW dry.
Given the low humidity values, gusty winds, and dry vegetation across South Florida currently, there have been quite a few wildfires noted on radar and satellite imagery this evening. Cooler afternoon temperatures and low relative humidities will make it feel that much nicer outside. A reinforcing cold front is currently working its way down the peninsula today. This will help reinforce the cooler and drier air. Sunday, with the aforementioned cold front moving through the region, another dry and cooler day across South Florida. High pressure will continue to build across the region and shift eastward. As the high shifts east, winds will become northeasterly and a little less breezy.
(This evening through Sunday) Warmer temperatures through the next 24 hours. The healthy southerly flow will also advect moisture into the area, helping to keep temperatures warm overnight, and lows are only expected to drop into the mid 50s to lower 60s, much warmer than the previous few nights when we were able to drop below freezing. There still may be a few isolated locations that are able to drop into the 40s, but most of the area will be much warmer.
207 AM EDT Sun Apr 10 2022 A deep upper level trough will maintain below-normal temperatures through tonight, with snow showers coming to an end near the border of North Carolina and Tennessee, and frost or freeze concerns for most of the region. This cold upper trough will be moving east on Sunday while being replaced from the west with an upper level ridge.
With the ArkLaTex situated in the warm sector south of the cold front and east of a dry line across Texas, discrete supercells will be the likely convective type late Monday afternoon.
336 AM EDT Sun Apr 10 2022 High pressure builds in today, and remains across the region through tomorrow.
850 mb temps will look to be in the 22-24 (C) range through the night ahead of a cold front. Lows tonight should range from the lower 40s to the lower 50s. By sunrise we should start to see the leading edge of the cold front enter our northwest zones with strong winds along and behind the front. For Sunday it should be a cooler day as the front tracks through the rest of the area by late morning. Winds will gust out of the north to northwest at 20-35 mph allowing good cooler air advection all day. A low pressure center in central Oklahoma will also move northeast during the night and could clip our far southeast zones with a slight chance of rain towards Monday morning.
Deep longwave trough axis is now just east of the CWA. The rest of the temp forecast is pretty much NBM deterministic as its generally on the higher side of guidance spread for highs and on the lower side for lows. Moderation period really gets going Sunday as an amplifying upper level ridge following the upper long wave trough will be steadily expanding north as it passes across the Mississippi Valley. A few showers may begin developing, mainly in SW MS down to possibly I- 12 , as an upper trough drops south across the Rockies and shear axis promotes those showers.
Despite the deep layered low remaining aligned to our north, lower level ridging is beginning to sneak in from the west. As a result, both the cooler boundary layer with todays addition of a hefty subsidence inversion based around 850 mb is maintaining stable conditions. Short Term Update - Through the overnight period, the giant low will finally begin moving out to see and lower level ridging will gain better footing across our area. Expect overnight lows to fall very broadly in the 60s, with the Lower Keys struggling to get into the mid 60s and portions of the Upper Keys near 60.
A very strong short wave will then move in, digging a deep upper level trough that will move into the Pacific Northwest Monday. The event will start Sunday afternoon into Sunday evening as a warm front moves north through the area. Winds will get gusty over the ridges and east of the Cascades. This will be followed by a strong cold front which will move onshore late Sunday night into Monday morning. Post frontal showers will continue Monday, supported by the upper trough over the area at that time. The trough will move out to the east Monday night, but short waves diving down the backside of the trough will keep lighter shower activity going.
419 AM EDT Sun Apr 10 2022 A secondary cold front brought another shot of cool and dry air over the Peninsula of Florida and the Keys yesterday. The cooler air coupled with clear skies, light winds, and low dewpoints will cause temperatures to plummet tonight with overnight temperatures near the low to middle 60s. Later today, mostly sunny skies will allow temperatures to climb to the the low to middle 70s but, the persistent northerly breezes will make conditions feel cooler today. The steering flow that has predominantly been cyclonic will become anticyclonic today as a high pressure over the eastern Gulf of Mexico builds into the Keys today. The high pressure will tighten the pressure gradient, acorss the local waters over the next several days.
Current surface analysis shows low pressure centered over south central SD with the frontal boundary stretching south through Nebraska. Upper level analysis shows the ridge axis centered over us, shifting to the east this evening and Sunday.
(Today and tonight) The low level jet was strong tonight with the San Angelo and Dyess Radars indicating 65 KTS in the second gates. A red flag warning is also in effect this afternoon as RH values will be falling well below 20 percent as temperatures rise into the lower 90s.
Temps will also fall below freezing along portions of the Upper Cumberland.
After a chilly morning with much of the area seeing low temperatures near to below the freezing mark, temps have already warmed into the upper 40s and 50s across the area thanks to sunny skies and a very dry atmosphere.
Forecast was updated for southwest Idaho as a distinct short wave trough and snow showers moved eastward across the area this morning. Get ready for a significant snowfall in the mountains Monday, and some wet snow accumulation in the valleys, as a strong upper trough comes in from the west. Models show a cold front moving through western Idaho Monday afternoon with heavier pcpn, stronger winds, and possible thunderstorms.
High pressure with dry conditions across South Florida. Cooler, drier weather today as a surface area of high pressure lingers over the peninsula of Florida to close out the weekend. Aloft, the pattern is a little more active with a mid-level trough departing into the Atlantic and zonal flow attempting to return from the Gulf. Sunday will be dry and cooler with sunshine across the area.
/Issued 341 AM EDT Sun Apr 10 2022/ Dry and warmer weather expected today as a weak upper level ridge moves eastward through the region. 28 High pressure sets up in the Atlantic and mostly zonal flow will start off the week. Ridging remains in place for the first half of the week keeping most of the SW dry.
Much warmer weather can be expected this week. As steep low-level lapse rates linger into mid-morning, a few of the snow showers are heavier in spots and may put down a quick coating in spots, and possibly another half-inch or so on the ridges. Rain chances should return late Sunday night and Monday as the trough and associated sfc warm front cross the Upper Ohio Valley region. The aforementioned ridging should help gradually moderate temperature on Sunday, and by Monday support forecast temperature to average values or greater (PIT: 60F/38F).
A trough digs into the Pacific Northwest tonight and Monday. Ahead of this trough there will be a strong upper-jet with decent fetch of Pacific moisture. As the midlevel trough and sfc reflection move east Monday night, the event turns more into a wraparound event from the northeast.
This high is also filtering in very dry air across the region. This will be brief as high pressure over the Florida Peninsula will slide east over the western North Atlantic tonight. As it moves over the Atlantic, the high will build, leading to freshening breezes once again.
Low and middle tropospheric water vapor channels have shown dry air flux this morning, with turbulent dry mountain waves noted lee of Appalachians ridges. As departing and large low pressure area releases grip on region, winds relax into evening and become light SW as high pressure migrates off FL and SE coast. Fine radiational cooling tonight, SW flow helps keep temperatures well above freezing in 40s preventing agricultural damage. Ridging aloft and at the surface keeps the area dry and sunny, with southwesterly flow at the lower levels providing plenty of warm air advection.
High pressure builds into the area today. Much warmer today, highs near seasonal averages, calmer winds and clear skies. This is as our longwave trough finally exits northeast and high pressure builds in behind it. No threat of frost or freeze tonight with lows in the low to upper 40s.
1030 AM EDT Sun Apr 10 2022 High pressure will bring dry conditions and rising temperatures through the middle of the week.
1012 AM EDT Sun Apr 10 2022 High pressure builds in today, and remains across the region through tomorrow.
Breezy conditions along the coast and ridges will gradually diminish today. Much cooler and showery weather will then continue through the end of the work week. Temperatures were in the 30s across most of the area, with lower to mid 40s along the coast and in the 40s and 50s across the higher elevations of Lake and Mendocino counties where gusty winds continue. Freezing temperatures have yet to be realized across Mendocino and N Lake counties, but winds in the valleys have mostly decoupled, and several more hours of radiational cooling are anticipated.
Cold front will move into NE OK mid to late afternoon to near the Interstate 44 corridor by mid evening.
The main trough axis will pass through east-central Wyoming and northwestern Nebraska this afternoon. As it does, expect another round of snow showers to develop across the Converse-Niobrara corridor in Wyoming and the Pine Ridge areas of northwest Nebraska. Dry slotting will likely limit precipitation totals for the majority of the CWA, but especially across the high plains east of the Laramie Range where westerly downsloping flow should help keep things on the dry side.
746 AM EDT Sun Apr 10 2022 High pressure will bring dry conditions and rising temperatures through the middle of the week.
619 AM CDT Sun Apr 10 2022 (Today and tonight) The low level jet was strong tonight with the San Angelo and Dyess Radars indicating 65 KTS in the second gates. A red flag warning is also in effect this afternoon as RH values will be falling well below 20 percent as temperatures rise into the lower 90s.
The clouds will keep overnight temperatures in the low to mid 50s.
556 AM EDT Sun Apr 10 2022 High pressure builds in today, and remains across the region through tomorrow.
Warm and windy conditions today as mid to upper level ridging prevails aloft and a 40-50 KT low level jet slowly makes it way across Southeast TX. Expect today's high to range once again in the low to mid 80s with southerly winds at 20 to 25 MPH with higher gusts during the afternoon hours. Lows tonight into Monday morning will range between the mid 60s to low 70s and will give us a warm start to the day leading to high temperatures in the mid to upper 80s inland ( :[ ), slightly cooler along the coasts. Some models indicate a chance for rain Monday as ridging weakens across Southeast TX and instability increases, however, soundings show most of the area to remain capped.
An area of low pressure and a broad upper level trough will cross the region today into this evening. While temperatures and dew point appear warm enough to support a rain event, would not be too surprised if light snow develops over the higher terrain areas of the Sisseton hills later this afternoon. An area of low pressure, along with an upper level trough will cross the area on Monday afternoon, bring the showers, and perhaps thunderstorms to eastern South Dakota and western Minnesota.
1223 PM CDT Sun Apr 10 2022 (Today and tonight) The low level jet was strong tonight with the San Angelo and Dyess Radars indicating 65 KTS in the second gates. A red flag warning is also in effect this afternoon as RH values will be falling well below 20 percent as temperatures rise into the lower 90s.

233 PM CDT Sun Apr 10 2022 Scattered showers and thunderstorms are possible tonight and Monday, as a cold front shifts through the Midwest. Cloud cover and precipitation will keep high temperatures cooler on Monday, in the upper 50s to lower 60s.
152 PM MDT Sun Apr 10 2022 Current surface analysis shows low pressure centered over central Wyoming, as well as a low level wave moving through eastern SD. Upper level analysis shows mild upper trough over the Northern Plains, with flow becoming more zonal this evening and Monday. Models are fairly consistent with moving the upper low out of the Pacific Northwest and pushing it into the Intermountain West as a closed low. Model agreement is coming into place showing the highest potential snowfall north of our forecast area, however significant snowfall is still expected along for our northern tier counties.
311 PM EDT Sun Apr 10 2022 Short Term (Rest of Today and Monday): High pressure with a benign weather pattern as we end the weekend and move into Monday. As we move into Monday, the high pressure will slide east of the peninsula with easterly flow re-established across South Florida.
A cold front trails southwest of the low into north central and western OK.
This has made for northeast winds across the island chain, making for dry and cooler weather. The only locations holding onto 40 degree dew points are the Lower Keys. The high pressure will continue its eastward trek and move out over the western North Atlantic by this evening and overnight.
319 PM EDT Sun Apr 10 2022 Cool high pressure builds in from the west through tonight, then slides off the Southeast coast Monday into Monday night.
125 PM EDT Sun Apr 10 2022 High pressure will bring dry conditions and rising temperatures through the middle of the week.
High clouds also moved in for the early afternoon, which should start to curb the temperature rise with highs this afternoon settling in the upper 50s in the warmest spots, possibly cresting into the low 60s. As we progress into the evening, gusty winds will continue through the evening, ahead of a weak cold front that will cross the region. Went with warmer guidance fr Monday, as the returning sunshine, warm start to the day, and gusty winds from the west-southwest will likely make for a warmer day than today. Monday Night Through Sunday Impacts associated with a strong low pressure system during the middle of the week will be of primary concern.
A lee trough will help enhance the downslope warming for the urban corridor.
Upper level ridging remains evident across the southeastern U.
139 PM EDT Sun Apr 10 2022 A rapid warming trend will occur to start the week as an upper level ridge builds over the area.
354 PM EDT Sun Apr 10 2022 High pressure will bring dry conditions and rising temperatures through the middle of the week.
Thus, temperatures tonight will be much warmer with Monday's lows ranging through the 40s.
305 PM EDT Sun Apr 10 2022 Cool high pressure builds in from the west through tonight, then slides off the Southeast coast Monday into Monday night.
Precipitation chances end Monday morning, with cooler temperatures behind the front.
Highs in the low 80s expected for Monday, except mid 70s coast due to sea breeze.
320 PM EDT Sun Apr 10 2022 Clearing is expected tonight with a widespread frost expected in the morning with high pressure directly overhead.
Current temperatures are in the low to mid 60s as of 9 PM. The GFS MOS guidance came in a little cooler than the previous run, and due to the clear skies, light winds, and no mentionable rain chances, have leaned towards the GFS guidance. Temperatures tonight will continue to be below normal, with temperatures quickly falling into the low 50s for most locations a little after midnight.
808 PM EDT Sun Apr 10 2022 Clearing is expected tonight with a widespread frost expected in the morning with high pressure directly overhead.
Some sprinkles are possible as an upper trough moves through this evening and tonight, but most areas will stay completely dry.
645 PM EDT Sun Apr 10 2022 Clearing is expected tonight with a widespread frost expected in the morning with high pressure directly overhead.
1020 PM EDT Sun Apr 10 2022 High pressure will bring dry conditions and rising temperatures through the middle of the week.
We have had several reports of 55-70mph winds, and had to expand the High Wind Warning to additional forecast zones this afternoon. Further to the north, we will have the upper level low slowly moving to the east and northeast, causing light rain/snow showers to occur through this evening. Winds will be breezy across the higher terrain by Monday afternoon.
Surface winds have increased considerably from the south now that high pressure has shifted to our east. A cold front that is currently developing to our west will continue to gather moisture before entering the mid state tomorrow night.
All of this will result in much warmer overnight temps, with lows early Mon more in the lower/mid 50s for most spots. Given the increase in cloud cover/rainfall, afternoon temps Mon may struggle to climb more than the lower 70s, before a bit more clearing allows highs on Tue to rebound into the upper 70s/near 80F. Showers/tstms look to increase again late Tue night from the west, as a potent upper low/trough axis rotates into the nrn/mid Plains. This sfc wave is still expected to drag a cold front thru the Plains states and into portions of the SE region Wed into Wed night. Drier/more seasonal like conditions will then filter into the area starting Thu, with highs mainly in the lower/mid 70s while overnight lows trend from the mid 40s/near 50F.
Meanwhile, an upper trough moving across northern NE is producing rain showers with a few lightning strikes across Sheridan and Cherry County. An upper trough from the Dakotas extends south into north central NE into this evening. A deep upper trough will dig across the Pacific Northwest into the Central Rockies Monday night.
Given the increase in cloud cover/rainfall, afternoon temps Mon may struggle to climb more than the lower 70s, before a bit more clearing allows highs on Tue to rebound into the upper 70s/near 80F. Showers/tstms look to increase again late Tue night from the west, as a potent upper low/trough axis rotates into the nrn/mid Plains. This sfc wave is still expected to drag a cold front thru the Plains states and into portions of the SE region Wed into Wed night. Drier/more seasonal like conditions will then filter into the area starting Thu, with highs mainly in the lower/mid 70s while overnight lows trend from the mid 40s/near 50F.
744 PM EDT Sun Apr 10 2022 A rapid warming trend will occur to start the week as an upper level ridge builds over the area.
723 PM EDT Sun Apr 10 2022 Cool high pressure builds in from the west through tonight, then slides off the Southeast coast Monday into Monday night.
818 PM EDT Sun Apr 10 2022 High pressure slides off the Southeast coast Monday into Monday night.
639 PM CDT Sun Apr 10 2022 Scattered showers and thunderstorms are possible tonight and Monday, as a cold front shifts through the Midwest. Cloud cover and precipitation will keep high temperatures cooler on Monday, in the upper 50s to lower 60s.
