246 PM EDT Sun Apr 24 2022 High pressure will continue dominating the region as it gradually slides southward to the SC Coast tonight then weakens late Monday.
While some cu may linger through the evening, MVFR cigs are expected to develop after 06Z Monday over Deep E TX/WCntrl LA, and quickly shift NNE across N LA/SW AR ahead of a cold front that will drift SE into NE TX/adjacent SW AR.
156 PM EDT Sun Apr 24 2022 A strong ridge of high pressure aloft will remain over the area through Monday keeping unseasonably warm temperatures in place.
1253 PM EDT Sun Apr 24 2022 The summer like day rolls on with temperatures already in the lower 80s in a few spots. The ridging in the mid and upper levels are slowly pushing east but likely remain an influencer of our weather here in Kentucky. A stacked, large, deep, but weakening storm system centered over MN early this morning will slowly drift northeast over southeast Canada during the short term period, and its trailing cold front will move into eastern KY from the northwest on Monday. On Monday, the system's upper trough will begin to move in from the west as the cold front enters the region, providing support for precip. The period begins with the forecast area being in the middle of cold frontal passage.
348 PM EDT Sun Apr 24 2022 Quiet and warm weather continues through Monday, with offshore high pressure maintaining an influence on the area.
355 PM EDT Sun Apr 24 2022 A cold front will approach from the west tonight and move across the area on Monday. Lows will be very warm once again, only falling into the lower to mid 60s. In general, favored a somewhat faster solution as even if the actual front is slower, there is usually a pre-frontal trough that ends up forcing convection. Cooler air moving in will bring lows back into 40s Monday night, with some upper 30s possible in west central Ohio and east central Indiana.
1037 AM CDT Sun Apr 24 2022 The low pressure center is now situated over west central MN. The eastern CWA isn't quite at advisory level winds, but expect an increase this afternoon as the low moves east, so no anticipated headline changes. Snow is light this morning and temperatures are rising above freezing. The low that has been affecting the area this weekend is currently spinning over far southeast ND. Gusty northwest winds are expected today behind this low. High pressure builds in tonight drawing in drier air. Relatively chilly temperatures are expected Monday night, with lows generally between 20 and 25 F (10 to 15 below normal), as high pressure noses in from the north.
A southeasterly flow will keep the beaches more mild tonight with lows in the upper 60s while inland locations will dip into the low 60s and possible the upper 50s across portions of inland southeast GA.
And while we're past the average date of the last spring freeze, due to the cooler weather, growing degree days have barely just begun, so no freeze headlines needed at this time.
1247 PM CDT Sun Apr 24 2022 (Today and tonight) Early this morning, scattered showers and thunderstorms have developed along a stalled cold front across the Big Country. The aforementioned cold front will slowly move south across the area this afternoon and evening. This time frame is when the higher potential for locally heavy rainfall exists, especially for our southern and eastern counties.
201 PM EDT Sun Apr 24 2022 Warm and mainly dry today, then a cold front brings showers and possibly storms to start the work week. High pressure brings dry, cooler weather mid to late week. Upper level ridging and dry air in the low levels are expected to maintain dry weather through the day, with high clouds drifting through and some scattered cumulus possibly developing during the afternoon. This afternoon, highs will rise into the 80s across the lowlands and 70s to 80s in the mountains. While mainly dry weather is expected to persist through tonight, moisture begins to increase as upper ridging shifts east and a cold front approaches from the west.
(18Z TAFS) A cold front has stalled across along the Pecos River this afternoon. (This afternoon through Monday night) Rain chances (for some) and cooler weather dominate the short term. A cold front as stalled across the eastern Permian Basin this afternoon with showers and thunderstorms moving northeast along this boundary. Moisture will override the cooler airmass at the surface Monday keeping some clouds and even a few showers in place for eastern portions of the area. High pressure settles over the area Monday night allowing for temperatures to drop well below normal.
342 PM EDT Sun Apr 24 2022 Dry weather is expected through Monday with high pressure in place. Temperatures will be near normal, but a bit cooler on the coast where afternoon onshore winds will develop.
215 PM CDT Sun Apr 24 2022 (Issued 215 PM CDT Sun Apr 24 2022) Tonight through Monday night: Strong low pressure trending northeast from north of Lake Superior has pulled a cold front through the area with winds shifting to the southwest and pulling cooler and drier air into the area. Well defined dry slot across WI with large shield of cold advection stratocu associated with the mid/upper low circulation. All in all, a cooler regime is expected with a much drier airmass.
These showers and storms will continue through the evening hours ahead of a cold front that will move through the region tonight into Monday.
337 PM CDT Sun Apr 24 2022 Clouds and a few light showers/sprinkles have wrapped around the departing area of low pressure this afternoon. but they will likely be at least close to freezing to start the day across much of the area Monday as a reinforcing shot of cold air pushes south.
High pressure hangs around today and begins departing Monday.
High pressure will prevail through the entire short term period. For tonight, the high pressure center will shift southward across the state through the overnight hours. Have the lowest values (around freezing) across the northwest zones. For Monday, a weak UL trof will move across the Central Plains.
Temperatures down around freezing tonight across the north and more widespread Monday night may bring into play some vegetative issues for areas that have seen enough spring development.
The upper ridge axis centered just east of the Appalachians will shift to near the E coast by Monday evening, as an broad upper trough approaches from the west. A cold front will be approaching our western border by late Monday. Record highs for Monday: Date Chattanooga Knoxville Tri-Cities Oak Ridge 04-25 88(2009) 89(1960) 87(1960) 88(2009).
Cooler and drier weather early this week. A cold front was slowly moving through the area this afternoon.
The island chain remains in the southern periphery of a robust high pressure sliding east off of the Eastern Seaboard. Over the next 24 to 36 hours, the high pressure will continue sliding east and weakening over the western Atlantic waters. An eastward propagating trough over the Northern Plains will help push the aforementioned high into the central Atlantic by midweek.
320 PM EDT Sun Apr 24 2022 A strong upper level ridge centered over the SE US will bring dry and unseasonably warm conditions through Monday.
Breezy easterly flow remains in place over the area, although speeds continue to decrease slightly as the high slowly weakens and the gradient relaxes. Given the nearby position of the ridge, (similar to today) a pronounced subsidence inversion will be present with dry mid-lvls.
Showers and thunderstorms will continue across portions of central and southern OK into north TX this evening/overnight although gradually beginning to shift out of the area as cold front pushes further south and drier air moves into the area.
1240 PM CDT Sun Apr 24 2022 An upper level trough will exit the region today leaving cooler dry air behind it. Seasonal highs in the low 70s is expected today and below normal highs in the low to mid 60s are expected for Monday.
300 PM MDT Sun Apr 24 2022 High pressure will maintain control of the weather across the area into the first part of the work week, bringing relatively quiet and warm weather along with it. In spite of high pressure situated over Northern Idaho, numerous fair weather cumulus clouds have developed across the area, with a few of these cumulus clouds just large enough to produce some light rain showers. The quiet weather will persist into the first part of the work week, as warmer air continues to arrive and help to build an upper level ridge across the area.
The low pressure center is now situated over west central MN. The eastern CWA isn't quite at advisory level winds, but expect an increase this afternoon as the low moves east, so no anticipated headline changes. Snow is light this morning and temperatures are rising above freezing. The low that has been affecting the area this weekend is currently spinning over far southeast ND. Gusty northwest winds are expected today behind this low. High pressure builds in tonight drawing in drier air. Relatively chilly temperatures are expected Monday night, with lows generally between 20 and 25 F (10 to 15 below normal), as high pressure noses in from the north.
We're on track for another warm day with high pressure still nosing in from the east. Southerly flow on the west side of the ridge is providing enough low-level moisture to support a blanket of cumulus across the area. Expect tranquil and mild conditions tonight with lows about the same or slightly warmer than last night. As a result, a cold front will move into the Lower Mississippi Valley region tomorrow. The ridge will begin to break down as the trough moves eastward, but dry air will linger across our eastern counties with most of the favorable, deep moisture confined to a thin corridor just along and ahead of the front.
Southwesterly flow aloft will be in place through the near term as our region remains positioned between an upper-level ridge just off the southeast US coast, and an upper-level trough currently over the Rockies. The trough will slowly progress eastward through the period, with its axis approaching the ArkLaTex region by Monday evening. At the surface, high pressure off the Eastern Seaboard allows for southeasterly flow to continue over the area. An associated cold front will slowly push southeastward on Monday, reaching central Mississippi by Monday night. 2 inches for these regions), subsidence from the deep-layer ridging will help keep measurable rainfall out of the forecast for today. As the aforementioned cold front approaches the region, isolated to scattered showers will begin developing for regions west of I-65, where PWATs increase to 1.
We continue to look for a cold front to reach our area on Monday with a good chance for showers and storms.
Wet weather will return Monday and before turning much cooler for the rest of the work week. as a high amplitude ridge over the region will help to supply us with sun filled skies and summery temperatures. Highs will be in the low to mid 80s across the majority of western New York. although it will be significantly cooler near the lakes where temperatures could be in the 50s to lower 60s. Max temps east of Lake Ontario will generally be in the lower 70s. but this low risk is probably not worth planning around.
314 PM EDT Sun Apr 24 2022 A low pressure system is currently getting pushed northeast through Minnesota, and as we head into tomorrow, the system will move farther northeast over Ontario. Even though this system is moving away from the Lower Ohio Valley, it's trailing cold front is moving towards us from the northwest. Tomorrow's passing cold front will separate highs from the mid 60s in southwest Indiana to the low 80s in and around Clinton County, KY. Monday night the showers and isolated thunderstorms will taper off as the cold front continues to push to the east.
130 PM MST Sun Apr 24 2022 High pressure will prevail across the region this week resulting in dry conditions and generally clear skies.
729 PM EDT Sun Apr 24 2022 A passing cold front will bring rain showers and storms tomorrow afternoon and evening. Previous Discussion: The center of an amplified ridge axis overhead will gradually shift ewd today in response to a digging trough centered near Hudson Bay in Canada. Conditions tonight should be rather tantamount to that of today, as intensifying swly flow behind that departing ridge promotes increased cloud coverage towards daybreak Monday. That aforementioned Canadian trough should shunt occluded nrn Plains low pressure newd, eventually driving a cold front toward the area on Monday and increasing precipitation chances. Ahead of this, moist, warm advection in swly flow should support a marginally unstable boundary layer by afternoon as dewpoints reach the low 60s across north and western zones.
Daytime highs across much of the central portions of Upper Michigan have topped 70 and dry air aloft mixing down has sent dewpoints into the low 30s in parts of the interior west and 40s central. Downstream, convection associated with the low's cold front supported by a stout LLJ at 925-850mb will support some shower activity, and maybe some thunder.
An upper level trough over the Central Plains will slide east overnight and into Monday, acting to weaken the ridge in the east. Small Craft Advisories remain in effect for the waters west of the Seven Mile Bridge with Small Craft Exercise Caution headlines elsewhere. This will be in response to an approaching upper level trough that will act break down and displace a persistent ridge that has been anchored across the eastern U.
516 PM EDT Sun Apr 24 2022 Warm and mainly dry today, then a cold front brings showers and a few thunderstorms to start the work week. High pressure brings dry, cooler weather mid to late week. Updated temperatures and dew points to reflect warmer and drier trends this afternoon. But ridging and dry air have allowed it to stay dry across the area. Highs today will rise into the 80s to near 90 degrees across the lowlands, and 70s to low 80s in the mountains. While mainly dry weather is expected to persist through tonight, moisture begins to increase as upper ridging shifts east and a cold front approaches from the west.
718 PM EDT Sun Apr 24 2022 A cold front will approach from the west tonight and move across the area on Monday. Lows will be very warm once again, only falling into the lower to mid 60s. In general, favored a somewhat faster solution as even if the actual front is slower, there is usually a pre-frontal trough that ends up forcing convection. Cooler air moving in will bring lows back into 40s Monday night, with some upper 30s possible in west central Ohio and east central Indiana.
948 PM EDT Sun Apr 24 2022 A cold front will approach from the west tonight and move across the area on Monday. Temperatures will remain above normal with overnight lows mainly in the low to mid 60s. In general, favored a somewhat faster solution as even if the actual front is slower, there is usually a pre-frontal trough that ends up forcing convection. Cooler air moving in will bring lows back into 40s Monday night, with some upper 30s possible in west central Ohio and east central Indiana.
High pressure will prevail across the region this week resulting in dry conditions and generally clear skies.
715 PM EDT Sun Apr 24 2022 Quiet and warm weather will continue through Monday with offshore high pressure maintaining an influence on the area.
633 PM CDT Sun Apr 24 2022 Clouds and a few light showers/sprinkles have wrapped around the departing area of low pressure this afternoon. but they will likely be at least close to freezing to start the day across much of the area Monday as a reinforcing shot of cold air pushes south.
730 PM EDT Sun Apr 24 2022 High pressure will continue dominating the region as it gradually slides southward to the SC Coast tonight then weakens late Monday.
An upper level trough slides into the area Monday, yielding persistent unsettled weather through most of the week. Uncertainty remains on if the trough will stick around at the end of the week, as there is potential for a ridge to move in for the weekend.
Dry conditions will continue overnight and into Monday as high pressure maintains control. Incoming cold front and associated showers still look to move in late Monday evening. Showers will spread into east TN tomorrow evening in advance of an incoming cold front but this will be after the end of the 00z TAF period.

High pressure will maintain control of the weather across the area into the first part of the work week, bringing relatively quiet and warm weather along with it. /ISSUED 300 PM MDT Sun Apr 24 2022/ In spite of high pressure situated over Northern Idaho, numerous fair weather cumulus clouds have developed across the area, with a few of these cumulus clouds just large enough to produce some light rain showers. The quiet weather will persist into the first part of the work week, as warmer air continues to arrive and help to build an upper level ridge across the area.
Tonight and Monday The main highlights from this forecast period are strong winds continuing into this evening, the potential for light precipitation, and the return of cooler temperatures. Following the passage of a cold front this afternoon, strong CAA and daytime heating has allowed strong 850mb winds (30 to 40 kts) to mix to the surface. With limited moisture following the cold front, anticipate little to no chance for precipitation this evening, except in north-central WI where some light showers are possible.
(Monday through Sunday) The cold front will exit the forecast area late tonight, with post-frontal precipitation tapering off Monday morning across far southeast OK. Drier and cooler weather will prevail for a couple of days as surface ridging (and lighter winds) settle across the area.
619 PM CDT Sun Apr 24 2022 The low pressure system will continue it's slow track northeast.

1031 PM EDT Sun Apr 24 2022 High pressure will continue dominating the region as it gradually slides southward to the SC Coast tonight then weakens late Monday.
A low pressure system is currently getting pushed northeast through Minnesota, and as we head into tomorrow, the system will move farther northeast over Ontario. Even though this system is moving away from the Lower Ohio Valley, it's trailing cold front is moving towards us from the northwest. Tomorrow's passing cold front will separate highs from the mid 60s in southwest Indiana to the low 80s in and around Clinton County, KY. Monday night the showers and isolated thunderstorms will taper off as the cold front continues to push to the east.
550 PM MDT Sun Apr 24 2022 Strong winds have continued across portions of southeast Wyoming & the western Nebraska Panhandle this afternoon, mainly for the high plains courtesy of ample low-level mixing & a belt of stronger 700 to 800 mb flow around 40 to 50 kts. Still have a few lingering snow showers, mainly in the vicinity of the Snowy Range, but would expect this activity to dissipate by this evening as the trough axis continues to shift eastward.
Scattered showers primarily over the higher elevations of northern Utah will taper off during the evening. A ridge will build in for Monday with temperatures warming to near average.
Showers/thunderstorms are anticipated ahead of a cold front moving slowly from northwest to southeast across the state Sunday night into the day on Monday. Across the northern terminals, KHRO/KBPK will while the other sites of KLIT/KHOT/KADF/KPBF/KLLQ will feel a wind shift from southwesterly/southerly winds to northerly winds later in the forecast period as the cold front traverses the state.
Overnight lows in the low to mid 60s inland and mid to upper 70s east of I-95.
627 PM CDT Sun Apr 24 2022 (This evening through Monday) Early this afternoon, a cold front extended from near Wichita Falls, southwest to Abilene and then west to near Midland. The main challenge will be the potential for a few severe storms late this afternoon and evening, primarily along the cold front/dryline intersection. The main severe threat will be across western portions of the Concho Valley and northern Edwards Plateau through early evening, where a few discrete storms may develop near the dryline/cold front intersection, within a moderately unstable airmass. Temperatures will be much cooler behind the front tonight and Monday.
(This afternoon through Monday night) Rain chances (for some) and cooler weather dominate the short term. A cold front as stalled across the eastern Permian Basin this afternoon with showers and thunderstorms moving northeast along this boundary. Moisture will override the cooler airmass at the surface Monday keeping some clouds and even a few showers in place for eastern portions of the area. High pressure settles over the area Monday night allowing for temperatures to drop well below normal.
Clouds over the mountains this afternoon will diminish this evening as a brief ridge moves over the region. This ridge will move east Monday.
Otherwise, expect another cool night under little cloud cover in the mid levels from the aforementioned trough to the west. Light northerly winds will continue to bring cooler temperatures seeing 30s to near freezing in northwest counties. Afternoon high temperatures only in the low to mid 60s.
(Today and tonight) Strong thunderstorms continue in the vicinity of the cold front, along the I-10 corridor.
347 AM EDT Mon Apr 25 2022 High pressure remains in control today with another round of mostly clear to partly cloudy skies along with above normal temperatures.
1221 AM CDT Mon Apr 25 2022 Convection, currently residing across our far northwest airspace attm will push south and east through the remainder of our airspace this TAF period in the wake of a strong cold front. Prefrontal south winds near 10kts currently will become NNW to NNE with speeds near 10-12kts with some higher gusts in the wake of the cold front this morning and today. /issued 1001 PM CDT Sun Apr 24 2022/ A cold front continues to slowly move southeast into the forecast area and is located near or just north of the Interstate 30 corridor. An isolated severe risk will continue until just after midnight when the mid- level trough moves northeast allowing the winds aloft to diminish slightly along with a further decrease in instability.
