(Now through Monday) Zonal flow aloft this afternoon will gradually turn northwesterly as an upper-level trough digs into the southeast US. This trough will continue pushing towards the east on Monday before sliding into the western Atlantic by Monday evening. At the surface, the cold front which passed through the area last night will continue to push further into the Gulf throughout the period as high pressure builds in from the north. This will allow for a cooler and much drier airmass to continue advecting into the region. Lows tonight will range from the low to mid 40s inland to the low 50s along the immediate coast.
255 PM EDT Sun Apr 21 2024 Low pressure across the southeast along a frontal boundary will bring light rain into southern Virginia and North Carolina today.
Highs will remain on the chilly side again today pushing into the lower 60s. Upper level ridge builds in from the West early this week and that will bring great weather with the start of a warming trend. Highs will be about 5 degrees warmer tomorrow pushing into the mid 60s. (Monday Night through next Sunday) We will see another cool night Monday night but should be a bit warmer than tonight and frost is unlikely.
Warmer on Monday with returning south winds. Highs bouncing back into the low to mid 70s area wide. (Today and tonight) Early this morning, the mid-level trough axis that brought much- needed rain to the area has moved eastward. The resulting stout inversion in the low-levels should help cloud cover to persist for most of the day. High temperatures are expected to reach the low to mid 60s, but this will depend highly on how much insolation can break through the clouds. Lows should fall into the low to mid 40s across the region.
Post frontal high pressure will usher in cooler and drier air through Monday. The highs, however, should actually be slightly warmer than today.
915 AM PDT Sun Apr 21 2024 Warm today and Monday with weak high pressure over the region.
(Rest of today through Monday) High pressure remains in control of the weather pattern this afternoon across South Florida as it pushes further into the western Atlantic. At the same time, a deepening mid level trough will continue to push southeastward from the Midwest this afternoon and through the Southeast tonight into Monday. The highest chances of strong to severe thunderstorm development still look to remain along and north of Alligator Alley.
Despite winds being on the lower side under 25 mph, the very dry air mass over our area along with presently dry fuels will increase the potential for fires to spread rapidly should a fire develop. Full sunshine expected today as high pressure drops to our south and winds turn more westerly today.
308 PM EDT Sun Apr 21 2024 An upper level trough with unseasonably cold air aloft will drift through eastern Canada and the northeastern states to close out this weekend. A widespread frost or freeze is expected across portions of the Commonwealth that have started the growing season recently across Central and Southern PA, as high pressure moves overhead and the sky clears.
The incoming drier, cooler airmass will bring much chillier overnight temperatures, particularly to north Georgia where lows will dip into the upper 30s for a number of locations by Monday morning. With high pressure overhead bringing calm winds and clear skies, temperatures Monday night will again be on the chilly side, ranging from the upper 30s to mid 40s across the area.
Cooler, more unsettled conditions look to return by the end of the week. While we remain fairly cloudless this morning, expect some clouds to develop through this afternoon, especially along the ridge lines of the higher terrain.
(This evening through Monday Night) Following a busy first half of the weekend, Sunday has been nothing short of beautiful across the Four State as temperatures have rebounded into the mid to upper 60's and clear skies have prevailed with high pressure influencing the FA. As a result, another cooler night is expected with lows ranging from the upper 30's across the north, to low to mid 40's elsewhere. By Monday, high pressure will sit directly overhead, continuing the theme of clear skies and calm winds. Given the dry airmass behind the frontal passage to end the week, and calm winds, elected to trend on the high side of the guidance for MaxT's Monday afternoon. As a result, look for highs in the low to mid 70's just about areawide.
/96 (Now through Monday) A cold front continues to push south into the marine area this morning. The rain will end from est to east by this afternoon as the upper trough moves east and drier air returns to the region. A cooler airmass has moved into the area in the wake of he front and high temps today will only be in the low to mid 60s inland to near 70 along the coast. Lows tonight will range from the low 40s inland to low 50s along the coast.
From synopsis, high pressure over the western North Atlantic will continue to retreat farther offshore this afternoon, with southeasterly breezes slackening across the Florida Keys coastal waters. High pressure building over the Southeast will bring moderate easterly breezes back to the Keys waters by the middle of the week, with fresh breezes developing later in the week.
1020 AM CDT Sun Apr 21 2024 - Warmer temperatures in the 60s finally return today.
242 PM EDT Sun Apr 21 2024 Cloudy skies will become mostly clear overnight, with temperatures dropping below freezing outside of most urban areas.
Calm to light winds across expected over much of the area overnight except for the higher elevations. For Monday, building upper ridge and surface ridging will produce a sunny day with light winds. Main concern is the low afternoon relative humidity with values in the 20s.
338 PM EDT Sun Apr 21 2024 An upper level trough with unseasonably cold air aloft will drift through eastern Canada and the northeastern states to close out this weekend. A widespread frost or freeze is expected across portions of the Commonwealth that have started the growing season recently across Central and Southern PA, as high pressure moves overhead and the sky clears.
314 PM EDT Sun Apr 21 2024 A cold front crosses tonight with little precipitation followed by a dry and blustery day Monday.
pdf Showers and storms will build across the forecast area this afternoon ahead of an advancing cold front moving in from out of the west, with gusty winds building in from out of the southwest. Potential for the formation of strong to severe storms will increase this afternoon as the trough ahead of the cold front interacts with diurnal heating this afternoon. Overnight low temperatures will drop down into the 50s and the lower 60s.
1228 PM CDT Sun Apr 21 2024 - Warmer temperatures in the 60s finally return today.
156 PM MDT Sun Apr 21 2024 -Gusty northwest Monday behind the cold front. Water vapor and upper level analysis shows a deep upper low over eastern Ontario with a long-wave trough extending down through the Ohio River Valley and another low over Alberta. In between these two features, weak upper ridging and zone flow is present over the western portions of the forecast area, with northwest flow continuing over the eastern CWA. At the surface, high pressure remains over the central Great Plains, extending into the Northern Plains, as a cold front extends southward through the northern Rockies from the Alberta low. The main concern for tonight and monday is wind speeds along and behind the cold front.
Aside from some high level cirrus clouds streaming over the region, skies are clear across the area this afternoon and temperatures are running about 5 to 10 degrees cooler than this time yesterday. Gusty north winds have kicked in along the coast due to a strengthening thermal trough. This thermal trough will induce east to northeasterly flow today and Monday, resulting in the Chetco Effect and warmer temperatures (compared to the rest of the coastal locations) in the Banana Belt region.
740 PM EDT Sun Apr 21 2024 A cold front crosses tonight with little precipitation followed by a dry and blustery day Monday.
731 PM EDT Sun Apr 21 2024 An upper level trough over Pennsylvania will lift out of the region early this week.
846 PM MDT Sun Apr 21 2024 - Warmer on Monday with a slight chance of afternoon showers and isolated thunderstorms.
756 PM EDT Sun Apr 21 2024 High pressure will shift off to the southeast through the day on Monday, leading to dry conditions and some moderation in temperatures.
Warmer on Monday with returning south winds. Highs bouncing back into the low to mid 70s area wide.
Despite winds being on the lower side under 25 mph, the very dry air mass over our area along with presently susceptible, dry fuels will increase the potential for fires to spread rapidly should a fire develop. The first cold front moves through the region from the west Monday morning. However, very dry air in the low levels will prevent much of this precip from reaching the ground, resulting in virga and/or very light, brief rain showers leading to little to no accumulation. Late Monday afternoon into evening, a second cold front moves through the region from the northwest. Again, dry air in the lower levels will limit the amount of precipitation reaches the ground, with most not seeing a wetting rain. Between 09-18Z, a cold front shifts winds out of the west again.
625 PM CDT Sun Apr 21 2024 (This evening through Monday Night) Following a busy first half of the weekend, Sunday has been nothing short of beautiful across the Four State as temperatures have rebounded into the mid to upper 60's and clear skies have prevailed with high pressure influencing the FA. As a result, another cooler night is expected with lows ranging from the upper 30's across the north, to low to mid 40's elsewhere. By Monday, high pressure will sit directly overhead, continuing the theme of clear skies and calm winds. Given the dry airmass behind the frontal passage to end the week, and calm winds, elected to trend on the high side of the guidance for MaxT's Monday afternoon. As a result, look for highs in the low to mid 70's just about areawide.
954 PM EDT Sun Apr 21 2024 High pressure will build across the area tonight and shift off to the southeast through the day on Monday, leading to dry conditions and some moderation in temperatures.
A cold front is expected to push across the state over the next 12-24 hours bringing showers and the chance for a few storms, with a cluster of showers and storms already having moved into parts of Levy County this evening. Mild overnight lows expected in the mid 60s to around 70 central and south, with northern/Nature Coast areas a touch cooler in the upper 50s to lower 60s. At the surface, the high pressure axis has shifted to our south as a cold front works into north Florida. Rain will come to an end in the evening, with drier air starting to move in over the region as high pressure builds over the southeast.
pdf Scattered showers and isolated storms along a cold front stretching from the SE GA waters to Suwannee Valley will continue to shift east- southeastward this evening. pdf Showers and storms will build across the forecast area this afternoon ahead of an advancing cold front moving in from out of the west, with gusty winds building in from out of the southwest. Potential for the formation of strong to severe storms will increase this afternoon as the trough ahead of the cold front interacts with diurnal heating this afternoon. Overnight low temperatures will drop down into the 50s and the lower 60s.
751 PM EDT Sun Apr 21 2024 An upper level trough over Pennsylvania will lift out of the region early this week.
(Rest of tonight) A rather strong mid-level vort max (within the base of a broader longwave trough across eastern North America) will continue to dig southeastward through the TN Valley this evening and into western portions of NC/SC by 12Z Monday.
622 PM CDT Sun Apr 21 2024 (This evening through Monday Night) Mostly sunny to partly cloudy skies can be found across all of Southeast Texas this afternoon in the wake of the late yesterday through early this morning rain producing system and associated cold front. High pressure settling into the area tonight combined with weakening winds and almost totally clear skies will help our overnight low temperatures to range from the low to mid 40s inland to the upper 50s at the coast. As the high moves off to the east, Monday's winds will swing back around to the east and southeast as the day progresses, and we will have high temperatures peaking in the low to mid 70s.
937 PM EDT Sun Apr 21 2024 Cloudy skies will become mostly clear overnight, with temperatures dropping below freezing outside of most urban areas.
Low pressure moving across southern Alberta and Saskatchewan will maintain windy conditions across the area through Monday with strongest winds continuing along the Rocky Mountain Front and near the Alberta border through this evening.
533 PM MDT Sun Apr 21 2024 - Warmer on Monday with a slight chance of afternoon showers and isolated thunderstorms.
Good radiational cooling should allow temperatures to fall into the lower 40s across North Texas with perhaps a few rural locations dropping into the upper 30s.
758 PM EDT Sun Apr 21 2024 Dry, high pressure will provide fair weather through mid-week.
632 PM EDT Sun Apr 21 2024 Cloudy skies will become mostly clear overnight, with temperatures dropping below freezing outside of most urban areas.
Skies will clear later this evening, allowing for overnight temperatures to plummet to near or below freezing across much of the region.
This isn't doing much to keep temperatures lower as high temperatures are about 6 to 10 degrees warmer than normal as broader ridging remains over the area. The ridge axis will be over our area Monday resulting in the warmest day of the period with a high around 95 in Tucson.
A cold front will approach overnight with ISOLD-SCT showers and ISOLD lightning storms possible. Gusty north winds will develop along the Volusia coast mid day behind the front as high pressure builds in, 20 mph gusting near 30 mph, and this will spread southward during the afternoon. A cold front slides southward thru much of the area overnight, accompanied by ISOLD-SCT SHRA's and ISOLD TSRA's. With a weak cold front approaching, we may see some scattered showers and isolated lightning storms developing from north to south (offshore-moving) across the local waters tonight. The cold front will promote a wind shift to out of the northwest overnight (north to south). Northerly winds will diminish Mon night (north to south) as the cold front pushes further into south FL. Rain chances are forecast to increase overnight into Mon ahead of an approaching weak cold front.
724 PM EDT Sun Apr 21 2024 Cloudy skies will become mostly clear overnight, with temperatures dropping below freezing outside of most urban areas.
723 PM EDT Sun Apr 21 2024 (Rest of today through Monday) High pressure remains in control of the weather pattern this afternoon across South Florida as it pushes further into the western Atlantic. At the same time, a deepening mid level trough will continue to push southeastward from the Midwest this afternoon and through the Southeast tonight into Monday. The highest chances of strong to severe thunderstorm development still look to remain along and north of Alligator Alley.
511 PM MDT Sun Apr 21 2024 -Gusty northwest Monday behind the cold front. Water vapor and upper level analysis shows a deep upper low over eastern Ontario with a long-wave trough extending down through the Ohio River Valley and another low over Alberta. In between these two features, weak upper ridging and zone flow is present over the western portions of the forecast area, with northwest flow continuing over the eastern CWA.

331 AM EDT Mon Apr 22 2024 High pressure will shift off to the southeast through the day, leading to dry conditions and some moderation in temperatures.
Cooler, more unsettled conditions return for the second half of the week. Cloud cover remains over much of the higher terrain, likely resulting in isolated virga.
(Today) Tranquil weather across the Tennessee Valley early this morning with high pressure in control. As of 07z, temperatures have fallen into the low to mid 40s and they should generally bottom out in the 37 to 42 degree range (with some slightly lower values across southern middle Tennessee). For the remainder of the day, we can expect plenty of sunshine, but northerly flow will help to reinforce this cooler air mass. As a result, temperatures will once again run below normal, with highs in the low to mid 60s being common once again.
1225 AM MDT Mon Apr 22 2024 - Warmer on Monday with a slight chance of afternoon showers and isolated thunderstorms.
124 AM MDT Mon Apr 22 2024 -Windy and slightly cooler today. Progressive NW flow will transition to western CONUS troughing this week as another deep upper trough moves out of the eastern Pac. Temps will be cooler than yesterday, but right around seasonal norms in the 50s and low 60s. A cold front will cross the area during the rest of the night followed by a period of gusty northwest winds.
Drier conditions beginning tonight with upper ridging building over the area through early this week.
103 AM EDT Mon Apr 22 2024 High pressure will build across the area tonight and shift off to the southeast through the day on Monday, leading to dry conditions and some moderation in temperatures.
1155 PM CDT Sun Apr 21 2024 (Rest of tonight) A rather strong mid-level vort max (within the base of a broader longwave trough across eastern North America) will continue to dig southeastward through the TN Valley this evening and into western portions of NC/SC by 12Z Monday.
117 AM EDT Mon Apr 22 2024 Cloudy skies will become mostly clear overnight, with temperatures dropping below freezing outside of most urban areas.
The high temperatures today will be in the low 70s.
pdf After yesterday's cold front, cool high pressure moves in from the north and northwest today, while strong mid/upper level trough expected to swing across through the forecast area. Highs today will be a good 8-12 degrees cooler than yesterday, with 70s most everywhere.
3) Otherwise, a broad ridge pattern builds into the area this week resulting in mostly dry and seasonable conditions. There will also be some rain showers spinning around this low, some of which will move across the northern zones of the forecast area this afternoon and evening. The low moves to the east tonight and high pressure moves in diminishing the winds.
315 AM EDT Mon Apr 22 2024 Cool high pressure will build into the region today. Temperatures will start to moderate heading into the middle of the week with the approach of a cold front.
1124 PM CDT Sun Apr 21 2024 (This evening through Monday Night) Mostly sunny to partly cloudy skies can be found across all of Southeast Texas this afternoon in the wake of the late yesterday through early this morning rain producing system and associated cold front. High pressure settling into the area tonight combined with weakening winds and almost totally clear skies will help our overnight low temperatures to range from the low to mid 40s inland to the upper 50s at the coast. As the high moves off to the east, Monday's winds will swing back around to the east and southeast as the day progresses, and we will have high temperatures peaking in the low to mid 70s.
Upper level troughing extends southward through the Ohio River Valley and lends support to an area of low pressure off the mid- Atlantic states. The associated cold front extends southwestward through the western Atlantic, across Florida and into the Gulf of Mexico. The high pressure moves east of Florida by mid-week allowing for a warming trend to set up over the state. (06Z TAFS) Some MVFR CIGs and SHRA possible over the next few hours as a cold front moves through the area. A cold front pushes through the eastern gulf waters with a chance of showers and storms over the next few hours. High pressure builds in behind this front by this evening and will dominate the weather with rain-free conditions through the week.
(Today and tonight) Sunnier and warmer conditions are on tap for today as northwest upper-level flow moves over the forecast area.
1117 PM EDT Sun Apr 21 2024 An upper level trough over Pennsylvania will lift out of the region early this week.
128 AM EDT Mon Apr 22 2024 (Rest of today through Monday) High pressure remains in control of the weather pattern this afternoon across South Florida as it pushes further into the western Atlantic. At the same time, a deepening mid level trough will continue to push southeastward from the Midwest this afternoon and through the Southeast tonight into Monday. The highest chances of strong to severe thunderstorm development still look to remain along and north of Alligator Alley.
1115 PM CDT Sun Apr 21 2024 High pressure will settle over the region overnight with clear skies, light winds and cold temperatures.
Sunny and slightly warmer today, but highs still 5 to 10 degrees below normal. With high pressure in control, it will be a beautiful and sun- filled day across the area. Temperatures will be slightly warmer than yesterday. A few areas of patchy frost are possible again tonight but temperatures will be slightly warmer so frost will be more isolated.
Temperatures are expected to warm quickly after sunrise as winds turn to the south advecting in much warmer air.
135 AM MST Mon Apr 22 2024 Unseasonably warm temperatures under mostly sunny skies will continue into midweek with the warmest readings occurring today as highs top out in the upper nineties across a good portion of the lower deserts.
1118 PM CDT Sun Apr 21 2024 High pressure will settle over the region overnight with clear skies, light winds and cold temperatures.
pdf Scattered showers and isolated storms along a cold front stretching from the SE GA waters to Suwannee Valley will continue to shift east- southeastward this evening. Showers and storms will build across the forecast area this afternoon ahead of an advancing cold front moving in from out of the west, with gusty winds building in from out of the southwest. Potential for the formation of strong to severe storms will increase this afternoon as the trough ahead of the cold front interacts with diurnal heating this afternoon. Overnight low temperatures will drop down into the 50s and the lower 60s.
Southerly winds should increase by noontime on the backside of the high, allowing temperatures to warm up to the mid 70s this afternoon. The southerly flow should also bring a moisture return in the low levels tonight. Given the increasing dewpoints overnight and warmer airmass, low temperatures should only fall to the low to mid 50s.
1021 PM CDT Sun Apr 21 2024 The high pressure is centered off to the east of the ArkLaTx and it is expected to build into the area over tonight and tomorrow.
1042 PM MDT Sun Apr 21 2024 -Gusty northwest Monday behind the cold front.
