1206 PM CDT Fri Mar 29 2024 (Today through Saturday) High pressure is now centered over the area and will slowly slide to the east over the next days. With the dry airmass in place, temperatures will jump into the low to mid 70s today and mid to upper 70s on Saturday. A few locally warmer areas may remain near 50 degrees, with the cooler locations will drop to near 40.
With a similar setup to,temperatures earlier today were able to dip into the lower 40s for much of the area. Coastal areas will remain a couple degrees cooler than inland areas as a sea breeze begins to develop later in the afternoon.
259 PM CDT Fri Mar 29 2024 - Dry weather continues into Saturday with cooler temperatures expected.
Afternoon heating acting on a marginally moist and unstable atmosphere will support scattered (generally 20-40 percent coverage) showers over the higher terrain.
(This evening through Saturday) Southwest flow aloft will continue over the forecast area as a closed upper-level low approaches the central California coast while ridging remains in place across the Midwest. Southwesterly surface winds will quickly drop off around sunset tonight and with gradually clearing skies, temperatures should be a few degrees cooler overnight compared to this morning. The combination of warmer weather and breezy afternoon winds will lead to at least elevated fire weather conditions on the Caprock.
1240 PM CDT Fri Mar 29 2024 GOES-16 Water Vapor satellite trends show a southern stream upper-level jet advecting Pacific moisture into the Southern Plains and into western sections of the Lower Mississippi Valley. Surface analysis late this morning places a 1024 mb ridge of high pressure over the Southeast United States. Winds are expected to increase this afternoon as a low-level jet moves slightly east into western sections of the Lower Mississippi Valley.
High pressure is in full control across the area as it drifts across the Southeast through tonight and settles into the Southwest Atlantic for the upcoming weekend.
It should come as no surprise that GOES-16 visible satellite imagery is depicting decaying fair weather cumulus cloud cover across portions of the Upper Keys, with sunny skies across the Lower Keys.
/16/ (Friday through Saturday) Very quiet weather is expected in the short-term, as subtle ridging slowly builds in over the next 36-hours. Outside of that, temperatures will begin to warm under the ridge, with highs today ranging in the upper-70s, and highs tomorrow sneaking into the low-80s.
403 PM EDT Fri Mar 29 2024 - A weak cold front will approach from the north on Saturday and stall near the Ohio River Saturday night, bringing us a possibility of showers.
1246 PM CDT Fri Mar 29 2024 - Front moving through today will bring cooler temperatures north, but temperatures will remain warmer further south across north central Kansas.
By the middle of the week, the next round of unsettled weather moves into the area bringing cooler temperatures and more moisture to the region. An upper level trof dominates the region, favoring periods of rain/snow and cooler temperatures. Additionally, from late tonight into the early morning hours of tomorrow, isolated areas of light freezing drizzle are possible. The most current numerical model runs reduce the probability of freezing drizzle, and due to the isolated nature of any freezing drizzle that may form, the plan is to utilize a Special Weather Statement (SPS) if confidence increases in the development of patchy dense fog and/or freezing drizzle.
Basically stretching from across the Arco Desert south and east with the highest QPF across the Utah border and nearby high country. In the lower valleys, model soundings support snow in the morning hours with temperatures near freezing and the freezing level just above the surface. Given the warmer road temperatures, don't expect much impact on the roadways but wouldn't be surprised to see some light accumulations on rooftops and grassy surfaces.
- A weak cold front will bring a northeast wind Friday night, and slightly cooler temperatures Saturday.
While the flow aloft is nearly zonal, lower level ridging and dry air dominates the area. Ridging across Florida will maintain moderate to fresh northeast to east breezes on Keys waters through the overnight period.
the high clouds will continue to exit and the weak frontal boundary to the northwest is expected to reach into Osage and Washington counties of Northeast Oklahoma around 12z Saturday. the southerly winds should continue to weaken through the overnight hours with gusts 15 to 25 mph mainly across parts of Southeast Oklahoma and the higher terrain of far Northwest Arkansas by early morning Saturday. Forecast lows in the 50s remain forecast with the cooler locations behind the frontal boundary in Osage/Washington counties.
/33/ (This evening through Saturday Night) Warmer than average weather will continue across the Four State Region through the rest of Easter Weekend. This is due to surface ridging having made its way further across the Mississippi River, maintaining southerly surface winds and warm air advection in the process.
632 PM CDT Fri Mar 29 2024 Tonight and Saturday: Continued dry through the period with warmer temperatures. Satellite imagery/RAP analysis had a low amplitude upper level ridge axis over the central CONUS. This upper level ridge will dampen further as it continues shifting east through Saturday as well. Although morning lows will be a few degrees cooler than normal in the east they will be near normal elsewhere. /22/ Mid-level zonal flow across the Lower Mississippi Valley and surface ridging due to a strong high pressure over the Florida Peninsula will keep the area dry this weekend through the beginning of the work week.
646 PM CDT Fri Mar 29 2024 (This evening through Saturday Night) Warmer than average weather will continue across the Four State Region through the rest of Easter Weekend. This is due to surface ridging having made its way further across the Mississippi River, maintaining southerly surface winds and warm air advection in the process.

1023 PM EDT Fri Mar 29 2024 Breezy conditions will subside late tonight as strong low pressure exits to the Canadian Maritime and high pressure briefly builds over Pennsylvania overnight. A weak area of low pressure and rain showers will cross the state on Saturday.
930 PM EDT Fri Mar 29 2024 High pressure will move off the Florida east coast tonight.
1001 PM EDT Fri Mar 29 2024 Breezy conditions will subside tonight as strong low pressure exits to the Canadian Maritimes. High pressure briefly builds over Pennsylvania tonight before a weak area of low pressure and rain showers cross the state on Saturday.
- A transition to freezing rain after midnight tonight across parts of north-central Wisconsin.
627 PM EDT Fri Mar 29 2024 High pressure will move off the Florida east coast tonight.
626 PM CDT Fri Mar 29 2024 (This evening through Saturday) Southwest flow aloft will continue over the forecast area as a closed upper-level low approaches the central California coast while ridging remains in place across the Midwest. Southwesterly surface winds will quickly drop off around sunset tonight and with gradually clearing skies, temperatures should be a few degrees cooler overnight compared to this morning. The combination of warmer weather and breezy afternoon winds will lead to at least elevated fire weather conditions on the Caprock.
610 PM CDT Fri Mar 29 2024 (Tonight) Issued at 121 PM CDT CDT Fri Mar 29 2024 High pressure located across the Southeast will keep dry conditions through the overnight hours.
/EC/ Tonight and Saturday: Continued dry through the period with warmer temperatures. Satellite imagery/RAP analysis had a low amplitude upper level ridge axis over the central CONUS. This upper level ridge will dampen further as it continues shifting east through Saturday as well. Although morning lows will be a few degrees cooler than normal in the east they will be near normal elsewhere. /22/ Mid-level zonal flow across the Lower Mississippi Valley and surface ridging due to a strong high pressure over the Florida Peninsula will keep the area dry this weekend through the beginning of the work week.
High pressure centered between AL/GA/FL along the Chattahoochee river will build further east over our area through the rest of the afternoon into this evening. As temperatures warm into the low/mid 70s inland away from the coast, highs will be more resistant to warm along the coast topping out in the mid/upper 60s due to the influence of cooler near shore waters. This evening, the high will hover over the area with clear skies through midnight and thin cirrus arriving from the west in the pre dawn hours towards sunrise as flow aloft in the mid and upper levels becomes more zonal over the region. Radiational cooling under the high will promote below normal lows in the low 40s north and west of highway 301, mid 40s over north central FL, and upper 40s to near 50 at the immediate coast.
Made minor adjustments lowering tonight's overnight lows by a few degrees across the Nature Coast and areas north of I-4 to better align between global and NAM MOS guidance which are a few degrees cooler compared to latest NBM output. High pressure is in full control across the area as it drifts across the Southeast through tonight and settles into the Southwest Atlantic for the upcoming weekend.
A large area of high pressure moving eastward into the southern Atlantic states has allowed a light return flow pattern to develop across much of the region. This should result in slightly warmer temps heading into early Sat compared to the last couple of mornings, with lows more in the mid 40s/near 50F for most spots.

This should result in slightly warmer temps heading into early Sat compared to the last couple of mornings, with lows more in the mid 40s/near 50F for most spots. As mid/upper level ridging amplifies across the eastern CONUS, both warm air and moisture advection increase.
114 AM EDT Sat Mar 30 2024 High pressure will move off the Florida east coast tonight.
101 AM EDT Sat Mar 30 2024 (Rest of today through Saturday) A gorgeous late "dry" season rest of the day remains in the forecast for South Florida as mid-level and surface ridging allow for quiet conditions to prevail. Although low-level moisture remains in the lowest portion of the boundary layer, there will not be much vertical extent to cloud cover/convection as the strong cap/inversion remains in place.
With a similar setup to,temperatures earlier today were able to dip into the lower 40s for much of the area. Coastal areas will remain a couple degrees cooler than inland areas as a sea breeze begins to develop later in the afternoon. (Saturday night through Sunday night) Upper level ridging builds into the area with high pressure easing off to the east. Highs will be in the lower 80s with lows warming from the 50s Saturday night to the 60s Sunday night.
Temperatures remain above freezing in the south central and southeast. Right now the highest confidence area for this is in the southwest where patchy fog remains in the forecast. Until a broad trough can kick this low out, periods of light will be possible across southern North Dakota Saturday afternoon through Saturday night.
An upper level trough will dig into the Southwestern CONUS on Sunday.
1134 PM EDT Fri Mar 29 2024 Breezy conditions will subside late tonight as strong low pressure exits to the Canadian Maritime and high pressure briefly builds over Pennsylvania overnight. A weak area of low pressure and rain showers will cross the state on Saturday.
(Today through Sunday) High pressure currently centered over Florida will drift eastward through Sunday. Lows tonight will be mild along with the high clouds and added moisture in place.
1211 AM CDT Sat Mar 30 2024 (This evening through Saturday) Southwest flow aloft will continue over the forecast area as a closed upper-level low approaches the central California coast while ridging remains in place across the Midwest. Southwesterly surface winds will quickly drop off around sunset tonight and with gradually clearing skies, temperatures should be a few degrees cooler overnight compared to this morning.

258 AM CDT Sat Mar 30 2024 - Some light freezing drizzle in the northern Red River Valley and northwestern Minnesota this morning, creating minor travel impacts.
Therefore, expected slightly cooler high temps behind it across NNW OK (low 70s) with upper 70s to mid 80s elsewhere ahead of it. Cirrus will increase late this afternoon through this evening from the southwest atop an upper ridge. Late tonight into early Sunday morning, a warm front will lift northward toward the KS/OK border.
There will be periods of higher clouds spilling over the upper ridge, and perhaps some lower clouds by early Sunday morning in moistening southerly low level flow.
331 AM EDT Sat Mar 30 2024 (Today through Sunday) High pressure and dry conditions are anticipated through the short term period.
Upper ridging will build into the area through the weekend keeping the local weather pretty quiet.
Although easterly low-lvl flow will prevail on the southwest periphery of the aforementioned high, the weak nature of the high/gradient will limit moisture return and airmass moderation (i.
There will be some breaks in the high clouds and this could promote some patchy fog development over the western Hill Country through mid-morning. Models show low clouds will continue to expand through the morning hours as southerly flow in the lower levels of the atmosphere remains intact.
(Today) Low amplitude ridging aloft continues over the region this morning, east of a deepening trough along the west coast.
209 AM EDT Sat Mar 30 2024 Breezy conditions will subside late tonight as strong low pressure exits to the Canadian Maritime and high pressure briefly builds over Pennsylvania overnight. A weak area of low pressure and rain showers will cross the state on Saturday.
Temperatures along the island chain are in the lower to mid 70s, with comfortable dewpoints in the mid to upper 50s, and winds on land from the east around 10 mph. Surface analysis depicts high pressure centered over the Florida peninsula. Aloft, flat ridging is located over the Gulf of Mexico, with generally zonal flow over much of the CONUS downstream of a deep cutoff low spinning off the central California coast.
338 AM CDT Sat Mar 30 2024 - After a slightly cooler and quiet day, periods of light rain and snow return to the region tonight into Sunday.
1212 AM CDT Sat Mar 30 2024 (This evening through Sunday) Broad upper ridging is over the area this afternoon, and with mostly clear skies and breezy SWrly winds, temps have warmed into the 70s for most. Expecting at least occasionally breezy conditions will persist thru the period as the aforementioned sfc cyclone ejects in the Great Lakes region by tomorrow, followed by additional lee cyclogenesis as mean upper troughing digs into the SWrn states this weekend. Ahead of this approaching upper trough, a broad warm sector will develop bounded by a dryline to our W across portions of TX/OK and a warm front to our N across portions of KS/MO/IL.
The 12z upper-air analysis shows some warm advection at low levels, which is consistent with an ensemble of BUKFIT model soundings that show a slight warming in the low levels today. -Warm temperatures return mid-week Current surface map places low across eastern Iowa with cold front through the Central Plains. Cool high pressure extends from central Canada into the Northern Plains. While shear at the top of the moist layer is weak, pattern could support some spotty freezing drizzle.
539 AM EDT Sat Mar 30 2024 Low pressure will track north through the Maritimes today.
A closed low is currently centered off the central California coast and will continue southward through the day today. This evening into the overnight hours the low will open up and move eastward along with its associated cold front. Initial precipitation will be along this cold front.
-Warm temperatures return mid-week Current surface map places low across eastern Iowa with cold front through the Central Plains. Cool high pressure extends from central Canada into the Northern Plains. While shear at the top of the moist layer is weak, pattern could support some spotty freezing drizzle.
(Today through Sunday) Concur with deterministic NWP model output that the upper pattern over the CONUS will be quasi-zonal today, with a flat ridge over the south central CONUS, while an upper disturbance enters the West Coast. The upper ridge axis moves east of the region Sunday, as the foregoing upper disturbance enters the Rockies/approaches the southwestern CONUS.
Latest satellite data continues to show a trough deepening off the southern California coast. Increasing low level moisture from southeast winds ahead of a lee trough is resulting in areas of low clouds across the Hill country into central Texas. Winds should pick up to the 15 to 20 mph range by mid morning as the surface pressure gradient tightens ahead of the upper trough.
(Rest of Today) High pressure will remain dominant around the region, keeping a dry and warming airmass in place. These winds will continue to promote warmer temps, and have adjusted highs upward slightly during the morning update.
Temperatures in the clear spot are dropping into the lower teens while temperatures under the lower clouds remain in the upper 20s to 30s. As a result, portions of south central North Dakota have stayed above freezing while the remainder of the state is close to the NBM 75th percentile for low temperatures. An upper level low off the coast of California will enhance troughing across Western CONUS today pushing an upper level wave across South Dakota. The upper level low over Western CONUS will begin to push through the Southern Plains missing North Dakota by the start of the work week.
A ridge will build in behind this low, bringing a return to dry weather across the area. The ridge will tighten the pressure gradient along the North Coast, promoting gusty winds along the coast. NBM shows a 40-50% chance for a wind gust over 45 mph on exposed ridges and coastal headlands Sunday, especially around Cape Mendocino.
649 AM CDT Sat Mar 30 2024 (Today) Low amplitude ridging aloft continues over the region this morning, east of a deepening trough along the west coast.
620 AM CDT Sat Mar 30 2024 (Today through Sunday) High pressure currently centered over Florida will drift eastward through Sunday. Lows tonight will be mild along with the high clouds and added moisture in place.
605 AM CDT Sat Mar 30 2024 - Will be monitoring for a short period of freezing rain this morning across Taylor and portions of Clark Counties.
As a result, portions of south central North Dakota have stayed above freezing while the remainder of the state is close to the NBM 75th percentile for low temperatures. An upper level low off the coast of California will enhance troughing across Western CONUS today pushing an upper level wave across South Dakota. The upper level low over Western CONUS will begin to push through the Southern Plains missing North Dakota by the start of the work week.
606 AM CDT Sat Mar 30 2024 - Some light freezing drizzle in the northern Red River Valley and northwestern Minnesota this morning, creating minor travel impacts.

612 AM CDT Sat Mar 30 2024 - After a slightly cooler and quiet day, periods of light rain and snow return to the region tonight into Sunday.
(Today through Sunday) High pressure and dry conditions are anticipated through the short term period.
832 AM EDT Sat Mar 30 2024 Beautiful day across South FL with high pressure remaining in control. Although easterly low-lvl flow will prevail on the southwest periphery of the aforementioned high, the weak nature of the high/gradient will limit moisture return and airmass moderation (i.
702 AM CDT Sat Mar 30 2024 (Today through Sunday) Concur with deterministic NWP model output that the upper pattern over the CONUS will be quasi-zonal today, with a flat ridge over the south central CONUS, while an upper disturbance enters the West Coast. The upper ridge axis moves east of the region Sunday, as the foregoing upper disturbance enters the Rockies/approaches the southwestern CONUS.
Radar is picking up a few showers in Siskiyou County and most of it is on I-5 from Dunsmuir to Grenada and these showers will continue wrapping around the upper level low to our south this morning. The low will be moving south today which will move the shower activity to the southeast. As the troughing moves eastward there will be a chance for a couple of showers on the back-end Sunday afternoon. As the low reaches central California, ridging will build in the area.
Conditions are expected to remain relatively quiet due to surface ridging building across the region as a high sits over the Florida Peninsula. This will allow for warmer temperatures and dry conditions through this evening. There will be periods of higher clouds spilling over the upper ridge, and perhaps some lower clouds by early Sunday morning in moistening southerly low level flow.
417 AM CDT Sat Mar 30 2024 - Will be monitoring for a short period of freezing rain this morning across Taylor and portions of Clark Counties.
An upper level ridge will continue to build into the weekend, continuing to bring dry and warm conditions through the region.
The Northern Rockies will continue to be under split flow through the weekend as a ridge of high develops over the Pacific Northwest and a large low pressure system tracks across California into the Great Basin region.
1250 PM CDT Sat Mar 30 2024 (Rest of Today) High pressure will remain dominant around the region, keeping a dry and warming airmass in place. These winds will continue to promote warmer temps, and have adjusted highs upward slightly during the morning update.
(Rest of today through Sunday) It'll be a beautiful weekend across South FL as high pressure to our east will remain in control. Light E/SE flow will result in warmer temps in SW FL today and Sunday, with high temps overall across South FL ranging from the upper 70s to lower 80s.
High pressure will bring clearing skies and a warming trend through mid-week. With cold air in place aloft, and warmer temperatures near the surface, low level lapse rates are impressive at near 9 deg C/km.
(Now through Sunday) Dry and mild is the theme of the local weather through Sunday thanks to upper level ridging. Cooler marine waters will keep immediate coastal areas a few degrees cooler for Sunday highs.
A closed low is moving south along the U. Another round of showers will occur on Sunday, but they will end earlier in the day due to a ridge moving into the region. A ridge from the northeast Pacific into British Columbia is moving south and will become the dominate weather feature over western Montana and central Idaho by Sunday evening.
