Overnight lows will fall into the mid 40s with some mid 30s across the highest elevation of northern GA. Tomorrow looks pretty similar, with winds swinging back to the SW as high pressure moves off the coast.
339 AM CDT Wed Mar 29 2023 Key Messages: * Cooler and breezy today behind cold front.
With southerly flow returning tonight, slightly warmer temperatures expected with lows in the lower 50s. High temperatures on Thursday will also be somewhat warmer, mainly in the 70s areawide with some locations across portions of deep east Texas and north Louisiana approaching 80 degrees. /05/ (Thursday Night through Wednesday) By Thursday evening, the ridge axis will be pushing eastward over the Mississippi Valley, making way ahead of the deepening trough over the Rockies.
126 AM EDT Wed Mar 29 2023 A cold front will bring gusty winds and a 1 to 3 hour period of rain and snow mixed late Wednesday morning into Wednesday afternoon, especially north of US-24.
Expect high pressure to persist across the region through the next 24 hours or so. By tomorrow afternoon, southwest flow will be well under way ahead of the low pressure system off the northern California coast. Southwesterly flow behind a departing ridge of high pressure will set the stage Thursday for the return of another round of remnant AR moisture fueled precipitation on the West Slope.
(Today through tonight) High pressure has settled into the region this morning. I will say, we have a ways to go to get to the low 30s, but even if we only get to the mid 30s, frost is still likely in many, if not most areas this morning. By Thursday, the ridge will move off to our east and put the region in a southerly PBL.
1014 PM MDT Tue Mar 28 2023 Water vapor shows low near Hudson Bay with flat ridge across the Northern Plains. Next upper low is just offshore the CA/OR coast. For tonight, jet streak embedded within the flat upper ridge will race across the region, with band of low-mid level frontogenesis producing some light snow from mainly the Black Hills into south central SD. On Thursday, upper trof works through the western CONUS. Warm front lifts through our area with some gusty southwest winds and mild temps as thermal ridge peaks. Could see a few showers in the west by later in the day as next cold front sweeps in from the west.
This will allow cooler air filtering in late tonight with lows dropping into the lower 50s interior SE GA, the mid to upper 50s interior northeast Florida and near 60 along the immediate First Coast beaches. Cooler air filters in tonight with lows dropping into the low 50s into low 60s. Cooler temperatures expected with high temperatures Wednesday ranging from the upper 60s in southeast Georgia to near 80 in north central Florida. Temperatures will increase slightly on Thursday as mid-level ridging builds into FL.
Winds will diminish during the early evening as the cold front moves farther away from our CWA. This warm advection will mean lows Thursday will be on the order of five degrees warmer than Wednesday.
257 AM MDT Wed Mar 29 2023 08z surface analysis had back door cold front from western MT to southeastern WY to southwest IA. Attention then turns to upper low spinning just west of northern CA. Result will be warmer temperatures, which have been painted near guidance.
The upper level pattern is fairly zonal in nature, and will amplify a bit on Thursday as a trof digs down across the west coast, resulting in a southwesterly flow aloft.
(Today through Thursday) High pressure is building on top of the area tonight. Winds will remain around 7 to 10 mph through midday and then begin to degrease as high pressure begins to center over the area. On Thursday the high begins to slide eastward and a southerly component begins to impact the area.
1246 AM CDT Wed Mar 29 2023 (Tonight through Wednesday night) The short term is still looking cool, wet and cloudy for Deep South Texas and the Rio Grande Valley, with a slightly cooler trend from the last forecast package. The cold front is now south of the Rio Grande, leaving gusty north to northeasterly winds, cooler air, and some showers and thunderstorms in its wake. With a persistent northerly flow through Wednesday and mostly cloudy skies, I decided to trend cooler than the previous forecast and the National Blend of Models (NBM) and topped out highs in the mid to upper 60s for Wednesday. Winds will veer to become easterly on Wednesday night and the onshore flow will allow lows to be slightly warmer than tonight.
(Today through Thursday) Last night's cold front has moved well out into the central Gulf of Mexico, ushering much cooler and drier air into the area. Much of the area was reporting dew points in the 40s, but ranged from the upper 30s over southwest Mississippi to the lower 50s at Boothville.

and Fri night lows in locations south and west of Blackfoot in those zones will have mild overnight lows, likely above freezing.
and Thursday Snow showers are likely this morning as a cold front moves across the region.
Otherwise, high pressure will continue to settle eastward into the Mid South/TN Valley regions later today, thereby maintaining quiet/tranquil wx conditions.
The 06Z raobs showed pressure falls across the Florida Peninsula due to a cold front, which is currently near the Big Bend of Florida. Overnight temperatures were in the mid 70s, and dewpoints were in the lower 70s. The cold front will gain some momentum today before fracturing and slowing late tonight in southern Florida.
649 AM CDT Wed Mar 29 2023 (Today through tonight) High pressure has settled into the region this morning. I will say, we have a ways to go to get to the low 30s, but even if we only get to the mid 30s, frost is still likely in many, if not most areas this morning. By Thursday, the ridge will move off to our east and put the region in a southerly PBL.
617 AM CDT Wed Mar 29 2023 (Today through Thursday) Last night's cold front has moved well out into the central Gulf of Mexico, ushering much cooler and drier air into the area.

Lows tonight will be warmer in the upper 30s to upper 40s. A warm front will lift NE into the state Thu night. Chances for convection will also increase with this warm front.
440 AM MDT Wed Mar 29 2023 MORNING DISCUSSION: Patchy freezing fog will linger along the Milk and Missouri River basins through mid morning before burning off by noon.
High pressure will settle over the region with dry weather through Thursday.
649 AM EDT Wed Mar 29 2023 High pressure will keep conditions dry through today and Thursday. A weak, but dry cold front will move out of New England and dissipate as it reaches the Mid Atlantic area tonight.
Deterministic model guidance continues to show a 700 mb low pressure circulation developing and moving through the region overnight, but maintaining differences on the track and strength of the low. The track of the low will need to be monitored for an area of heavier snow.
Much cooler today, as high temperatures remain in the upper 70s to lower 80s. Onshore flow and cooler shelf waters will actually help keep much of Volusia and northern Brevard Counties in the lower to mid-70s! A high risk of rip currents continues at area beaches.
644 AM CDT Wed Mar 29 2023 Key Messages: * Cooler and breezy today behind cold front.

The large upper level low continues to spiral offshore this morning, slowly drifting to the southeast towards the central California coast.
830 AM EDT Wed Mar 29 2023 Dry weather is expected through tonight under an area of weak high pressure. A crossing cold front will return rain and snow showers to the area Wednesday afternoon and evening.
By Thursday, conditions are forecast to be much drier as mid- level high pressure builds over the Gulf of Mexico. As mentioned in the previous forecast discussion, temperatures have trended cooler and cooler for today and tomorrow. Since NBM still seems to be running a bit warm, blended previous forecast/CONSShort to keep consistency with the cooler temperatures. Thursday will be almost 20 degrees warmer in the 80s with partly cloudy skies.
1246 PM CDT Wed Mar 29 2023 Key Messages: * Cooler and breezy today behind cold front.
241 PM EDT Wed Mar 29 2023 A crossing cold front will return rain and snow showers to the area this evening.
342 PM EDT Wed Mar 29 2023 Colder air will arrive behind a cold front this evening, along with a few showers. After a dry period on Thursday, a stronger low pressure system will approach from the west on Thursday.
1247 PM CDT Wed Mar 29 2023 (Today through Thursday) A weak mid level short wave trough moving across south Texas this morning will interact with an elevated moist layer to keep a chance of showers over the coastal plains this morning into early afternoon. Low pressure will deepen over the southern high plains Thursday as a mid level trough moves across the central Rockies. The frontal boundary will move north of the region Thursday as a warm front. Highs will be warmer Thursday with readings near normal.
Temperatures are currently in the lower 80s, with dew points near 70. Satellite analysis depicts a weak cold front located in central Florida. As the cold front continues to track south throughout the day on Thursday, rain chances should decrease. Fresh breezes in combination with the available atmospheric moisture in the low levels may cause speed convergence shower development and POPs may need additional tuning.
Expect these to continue for a few more hours, before a large area of high pressure moves further east into the area. 7 AM Soundings show very dry air aloft that will likely mix down to the surface after temperatures reach the lower to mid 50s. Current temperatures are just reaching the lower 50s in many locations near the Tennessee River. Thus, highs should still climb into the lower to mid 60s in most locations this afternoon.
An upper level trough will be moving through our CWA this afternoon, which will cause mild instability in the atmosphere and create some rain showers and moderate thunderstorms to the east side of the San Joaquin Valley and the Sierra Nevada foothills likely around 4 PM.
Low temperatures tonight will be warmer than this morning and even warmer Thursday night while high temperatures warm to near normal on Thursday.
247 PM EDT Wed Mar 29 2023 (This afternoon through Thursday) Fair weather conditions are expected to continue through Thursday as a result of high pressure. As high pressure slides off the east coast winds will swing back to the SE and eventually SW. Similar to today, minimum RH values across North GA will fall into the low 20% range.
As the mid level closed low meanders eastward across central Idaho and southwest Montana, a distinct boundary of precipitation will form which will bring steady moderate snow tonight and thus the higher amounts.
159 PM PDT Wed Mar 29 2023 A large area of low pressure will continue to move along the coast of California through Thursday, leading to cold temperatures, gusty winds and periods of rain and mountain snow.
145 PM EDT Wed Mar 29 2023 Canadian high pressure will build across and offshore the Carolinas through Thursday.
906 AM MDT Wed Mar 29 2023 Morning Update: Given the ConsShort guidance better matching with the lower visibility observations along the Milk and Missouri River valleys this morning, I went ahead and blended that in with this morning's forecast. -Enriquez PREVIOUS DISCUSSION: Patchy freezing fog will linger along the Milk and Missouri River basins through mid morning before burning off by noon.
1221 PM CDT Wed Mar 29 2023 (Today through tonight) High pressure has settled into the region this morning. I will say, we have a ways to go to get to the low 30s, but even if we only get to the mid 30s, frost is still likely in many, if not most areas this morning. By Thursday, the ridge will move off to our east and put the region in a southerly PBL.
Early afternoon satellite imagery shows a large area of low pressure working south off the CA coast of which is expected to move onshore tonight into central CA with the 500 mb low favored to track directly overhead for Thursday into ERN ID. A cold front passing through the area this afternoon and evening will help transition any remaining rain showers to all snow as drier conditions fill in behind the front outside of continued mountain snow showers. As the low moves overhead, wrap-around bands of snow will work in throughout the day Thursday with widespread snow showers expected.
(This evening through Thursday) High pressure over the southeast will slowly move east through the short term. Flow will transition to the south and southwest overnight as the high moves across the state. Warmer air and moisture will begin to advect into the region with this flow. With high pressure and southerly flow. dry weather and temperatures in the low to mid 70s will be expected Thursday.
227 PM EDT Wed Mar 29 2023 High pressure will provide dry weather through Thursday as a warming trend takes place.
A cold front is currently pushing through Florida and is right now just north of Charlotte County. We will still warm up quickly to the mid to upper 80's but the lower humidity will still make it slightly more comfortable.
(Tonight) High pressure over the area has allowed winds to become calm or very light across most locations in northern Alabama and southern middle Tennessee. Dewpoints have dropped into the lower 20s in some areas, especially in southern middle Tennessee.
1218 PM EDT Wed Mar 29 2023 High pressure will provide dry weather through Thursday as a warming trend takes place.

Some drying will work into the lower Snake Plain through early afternoon, but expect the snow to continue in the central Idaho mountains through the day.
Expect dry and quiet conditions through tonight with high pressure at the surface.
126 PM EDT Wed Mar 29 2023 High pressure will provide dry weather through Thursday as a warming trend takes place.
That said, the low temp forecast is rather tricky tonight as we try to balance out how long near-ideal radiational cooling lasts before the southerly winds and warm air advection kicks in, and higher clouds. Expecting some warmer 40s and 50s across the southwest CWA, but this is a tricky high temp forecast as well since there is some debate on how far east into the CWA these warmer 925mb temps push. Will have to keep an eye on freezing rain/drizzle potential across eastern areas Thurs afternoon into the evening hours, as soundings support this to some extent. During the overnight hours, we keep the potential for freezing precip going, and pushing back to the west a bit, although the window for that seems much more brief than say, areas across the southeast CWA.
Top of the hour obs show light rain showers at Tyler to Henderson and over into Sabine parish now with Peason Ridge measuring now. /24/ (Thursday Night through Wednesday) By Thursday evening, the ridge axis will be pushing eastward over the Mississippi Valley, making way ahead of the deepening trough over the Rockies.
Overnight, southerly winds should remain fairly steady as a deepening upper level trough out west strengthens.

Behind the front, lower dew points are starting to fill into northern Florida, and the forecast looks on track for a somewhat cool start to the morning on Thursday, with lows in the low 50s over the Nature Coast and upper 50s to mid 60s farther south.
(This afternoon through Thursday) Fair weather conditions are expected to continue through Thursday as a result of high pressure. As high pressure slides off the east coast winds will swing back to the SE and eventually SW. Similar to today, minimum RH values across North GA will fall into the low 20% range.
Upper analysis shows an upper ridge crossing the great plains ahead of an upper low/trough currently crossing the California coast. The surface cold front will move back eastward as a warm front tonight into early Thursday. Warmer temperatures will occur on Thursday over most of the forecast area, except possibly over far northwestern South Dakota, dependant on how far north the front moves during the day on Thursday.

The upper low responsible for the heavy snow in the Sierra and Spring Mountains will continue to push east and southeast through Thursday. The deep upper low responsible for the heavy snow in the Sierra and Spring Mountains is currently spinning off the San Fransisco coast. This low will continue to track south and east and is forecast to become an open wave and push through Nevada on Thursday. The southern Sierra received between 12-18 inches of snow overnight, but has since stopped as of this morning, but as the low pushes inland this evening, we can expected to see snow increasing once again. Shower chances will decrease over most areas overnight, but as the main dynamics associated with the trough move overhead Thursday combined with afternoon heating additional showers along with isolated thunderstorms will be possibly, especially over Mohave County.
Strong, veering winds in the low-levels look to yield significant storm relative helicity as well. MJ High pressure aloft will permit dry weather through Thursday.
As the upper low that brought repeated rounds of precipitation continues it's trek south into southern California by Thursday morning, a weak short wave slides down the back of the offshore ridge, bringing showers as lapse rates increase again with warming.

Flow will transition to the south and southwest overnight as the high moves across the state. Warmer air and moisture will begin to advect into the region with this flow. With high pressure and southerly flow. dry weather and temperatures in the low to mid 70s will be expected Thursday.
High pressure remains in control across the ArkLaMiss region allowing for quiet conditions. Expect dry and quiet conditions through tonight with high pressure at the surface.
A large high pressure system expanding across the eastern United States is beginning to exert control over the Keys area. This evenings sounding indicated weak low level inhibition with modest dry air through the lower and mid levels. Also by morning, the remnants of an old cold front, currently draped over South Florida will begin moving southward across our area. A ridge expanding throughout the eastern United States will result in modestly strengthening breezes shifting out of the northeast to east northeast through the overnight period.
