617 PM CDT Mon Oct 28 2024 (Tonight through Tuesday night) Key Messages: A mid level high pressure system is forecast to track northeast across TX tonight through Tue morning as a deep long wave trough pushes southeast across the western U. This will lead to a tightening of the surface pressure gradient, thus strengthening S-SE winds in the lower levels. As the upper long wave trough approaches the region, a weak embedded short wave is progged to track N-NE across S TX on Tuesday. Despite the increase in moisture and the short wave, rain chances will remain low (10-24%) due to the moisture being confined to the lower levels.
608 PM CDT Mon Oct 28 2024 A large upper level high pressure ridge centered over the Southeast U.
High pressure aloft and at the surface will continue for the week, with the pressure gradient tightening some with an approaching system out of the west.
Overnight lows will be in the upper 50s for far interior SE GA, the lower 60s along the Suwannee Valley region towards the US-301 corridor in NE FL, and in the upper 60s along coastal locations, where coastal may begin to move onshore during the predawn hours. pdf High pressure will extend across the southeastern US, with an inverted trough over the coastal waters. The presence of the trough will keep skies mainly cloudy near the coast with partly cloudy skies inland.
644 PM EDT Mon Oct 28 2024 High pressure will prevail this week.
925 PM EDT Mon Oct 28 2024 Some showers Tuesday along the coast due to a coastal trough.
1008 PM EDT Mon Oct 28 2024 High pressure will prevail this week.
Needless to say, temperatures tonight will be considerably warmer than last night.
617 PM EDT Mon Oct 28 2024 Upper ridging is moving over the region through the end of the week, bringing a warming trend and dry conditions back to the area for much of the rest of this week.
(Tonight) Upper level ridging in place over the Texas/Mexico region should build to the NE and be situated across the Deep South late tonight and on Tuesday. A few high altitude clouds were moving this way, as troughing becomes established over the western CONUS the next couple of day. This is considering "normal" highs this time of year are in the lower 70s, and low temperatures in the mid 40s. With a steady SE wind of 5-15 mph and some higher gusts, low temperatures should cool into the lower 50s NE Alabama to near 60 mainly west of the I-65 corridor.
1008 PM EDT Mon Oct 28 2024 An upper ridge builds across the area Tuesday through late week providing above normal temperatures with continued dry weather.
526 PM EDT Mon Oct 28 2024 Record breaking heat is expected tomorrow through Halloween under a strong ridge.
739 PM EDT Mon Oct 28 2024 (Through Tuesday) The low stratus which filled in this morning behind a back door cold front is about done burning off for the day.
- A few strong to severe storms possible Wednesday along a cold front. Broad southwest flow is moving onto the Plains this afternoon as troughing continues to deepen out west. This has promoted deepening low pressure in the lee of the Rockies, with a strengthening pressure gradient boosting southerly winds across the area. Aside from the winds, the strong WAA will keep very warm temperatures ahead of the approaching cold front. The main negative though will be the motion of the cold front.
Broad upper ridging extends northward encompassing the entire eastern seaboard. The surface reflection is a strong high pressure center off the New England coast. This high pressure will ridge southwest over Florida and into the Gulf of Mexico producing gusty northeast winds for the next few days.
300 AM EDT Tue Oct 29 2024 A few showers are possible north of Pittsburgh this morning with a crossing warm front.
(Today through Wednesday) High pressure remains over the Mid-Atlantic, resulting in east- southeasterly flow across the area.
410 AM EDT Tue Oct 29 2024 A few showers are possible north of Pittsburgh this morning with a crossing warm front.
A broad high pressure dome over the eastern United States will shift southeastward into the North Atlantic and toward the Equator. A brief slackening to the moderate to fresh regime is expected later in the week as the high moves further east into the Atlantic. This reprieve will not last long as another high pressure system builds over the northeastern US over the weekend. From synopsis, a 1035 mb dome of high pressure will move into the North Atlantic from the northeastern United States this morning and continue equatorward during the week.
1137 PM CDT Mon Oct 28 2024 A large upper level high pressure ridge centered over the Southeast U.
Additionally, there is a deep upper level trough located across the western US that will push towards the east through the short term period.
The cold front currently sits somewhere along or just east of the RRV. A frontal boundary pushes towards the southeast filtering in cooler air behind it. These clouds will stabilize the overnight temperatures and keep us above freezing in the high 30's and low 40's.
Needless to say, temperatures tonight will be considerably warmer than last night. The weak and shallow pushes of cooler just get quickly eroded by higher/rising height levels and a continuation of double digit 850 mb temps. This will pair with a rather strong upper high which will be centered over the mid state on Tuesday. With highs in the lower 80s this will still be a couple degrees shy of the daily records.
1250 AM EDT Tue Oct 29 2024 High pressure will prevail this week.
07Z water vapor imagery showed an upper trough over the Great Basin extending south over the Baja Peninsula. Surface obs places a low over northwestern KS and the central high plains with an inverted trough extending northeast into MN. Models cool 925mb and 850mb temps from yesterday so highs are forecast to be a few degrees cooler than yesterday's highs. A cold front is on track to push southeast through the day, exiting east central KS around 03Z.
(Today through Wednesday) Some light showers are noted early this morning from the middle Texas coast northward into portions of the Highway 77 corridor. An uptick in the low-level jet will also lead to another low chance for showers for the Hill Country eastward through the I-35 corridor and coastal plains beginning early Wednesday morning.
The axis of the trough responsible for the upcoming storm system is currently spanning the west coast and will drop into the Great Basin tonight through tomorrow morning. With a cold front moving through tomorrow morning, noticeably cooler temperatures are on tap. Some of the lower valleys are on track for their first fall freezes Tuesday night/early Wednesday. On Wednesday the trough axis crosses the Divide leaving west to northwest flow in it's wake. The cold air from this system really settles in overnight and the clearing will support these cooler temps.
(Today and tonight) Our area remains entrenched in easterly to northeasterly flow on the southern side of high pressure. A plume of higher moisture will move in from the east later today, which may be enough for a shower or two to pop up this afternoon near the lower Suwannee Valley. Highs will be in the lower to middle 80s with mainly sunny skies. Another round of patchy fog will be possible near the I-75 corridor tonight, but otherwise a quiet night is in store with lows in the lower to middle 60s.
- The Halloween forecast is dry, with temperatures in the lower 40s in the evening. Cooler air will also filter in aloft as the trough axis nears western North Dakota. With the rain falling before and ground temperatures above freezing, accumulations are not expected. The rain will end west to east Wednesday afternoon as high pressure then moves in from the west. Most models have the residence time for the rain the highest in the south central.
239 AM EDT Tue Oct 29 2024 High pressure builds in the next several days, with coastal troughing offshore. Warmer weather returns mid to late week.
An upper level ridge centered over the Southeast U.
421 AM EDT Tue Oct 29 2024 Upper ridge will bring a warming trend and dry conditions back to the area for much of the rest of this week. Expect this cloud cover to move into the area over the next few hours, helping to level temperatures off in the low 50s or upper 40s near the SC/NC border. Upper ridging will be centered overhead at the start of the period, gradually sliding east as a trough translates from the Intermountain West to the Great Lakes region. At the surface, high pressure to our east will dominate our weather with east winds gradually shifting southeast then south.
341 AM EDT Tue Oct 29 2024 High pressure builds in the next several days, with coastal troughing offshore. Warmer weather returns mid to late week.
Much cooler temperatures across the forecast area starting today as a weather system pushes through. Freezing temperatures are expected tonight in the coldest valleys south and east of Tucson.
An upper level trough will be lifting out of the Four Corners Region pushing the ridge east but we will get one more quiet day.
1217 AM EDT Tue Oct 29 2024 High pressure will prevail this week.
(Today through Wednesday) A large mid-level trough will continue to dig over Four Corners region then swing eastward into the Plains through the period. At the surface, low pressure develops across the Plains will allow the pressure gradient to strengthen along the Lower Texas Coast through the period.
(Today through Wednesday) Generally benign weather conditions will prevail across South Florida through the short term as an extensive area of high pressure sits over the southeastern US. Nevertheless, enough low level moisture, and some weak forcing provided by a weak upper-level trough dropping along the peninsula, may allow for isolated showers each afternoon. High temperatures will reach the low to mid 80s each day, with overnight lows in the upper 60s for the lake region, and the low to mid 70s over the Gulf and East Coasts.
75 inches, with the higher amounts occurring over Corson and Dewey Counties. BUFKIT profiles in the NAM/GFS and ARW are drying out despite the upper low lingering overhead.
A trailing cold front will surge SE into the state late Wed night.
Highs today are in the upper 60s to 70s across the CWA and will be only a bit warmer tomorrow.
Do expect the low clouds to fill back in overnight Tuesday/early Wednesday. However, have blended in some slightly cooler guidance in for today.
1143 PM EDT Mon Oct 28 2024 Record breaking heat is expected tomorrow through Halloween under a strong ridge.
- Cooler/ more seasonable temperatures near the end of the work week and into the weekend. with a secondary warm front now moving into Western Wisconsin. strengthening lift ahead of the warm front. increasing low level moisture and some limited/elevated instability are resulting in convective development well in advance of this secondary warm front. Elongated area of convection will continue to develop and move thru our CWA from SW to NE primarily during the morning hours in advance of the approaching secondary warm front. Warm front will lift thru our CWA during early afternoon. Pattern Synopsis: Upper-level ridging will continue unseasonably warm temperatures (potentially record breaking) for Wednesday.
pdf Easterly winds continue today as high pressure sits to the northeast of the region, this pattern will bring more clouds and slightly cooler temperatures near the coast. Showers will move onshore this afternoon, with the highest coverage expected along the I-95 corridor south of Jacksonville, isolated thunderstorms cannot be ruled out as well. Temperatures will be relatively near normal, with highs in the low 80s for most inland areas, and upper 70s near the coast. Onshore winds will keep low temperatures mild near the coast, only dropping into the lower 70s, with some isolated showers possible tonight as well near the coast.
1119 PM EDT Mon Oct 28 2024 Record breaking heat is expected tomorrow through Halloween under a strong ridge.
Warm and dry conditions continue as high pressure builds aloft. Discussion: Upper ridging strengthens over the southeastern CONUS during the period while strong troughing digs out west. The forecast H85 winds do exhibit a little downslope tendencies today so areas in the foothills may wind up being warmer than some locations further out in the valley.
Highs 10 to 20 degrees above normal for late October in the lower to middle 80s.
139 AM EDT Tue Oct 29 2024 Upper ridging is moving over the region through the end of the week, bringing a warming trend and dry conditions back to the area for much of the rest of this week. Broad upper ridging will continue to develop over the eastern US Tuesday and into Wednesday. High temps will continue to increase as the broad ridging aloft remains nearly stationary and southerly component flow continues. Highs should push into the low 80's, well above average but not quite near record highs.
Snow accumulations expected across northeast WY to the Black Hills, especially the higher elevations. Upper air analysis shows a high amplitude trough across the western CONUS, with deep southwest flow over the central/northern Plains. Surface obs show a cold front just pushing into. With lower elevations, it will be harder to get accumulating snowfall during the daytime hours tomorrow, plus surface temps look to be hovering just above the freezing mark. Precip will end during the day on Wednesday, then dry weather is expected through the rest of the week as upper ridging crosses the area.
101 AM EDT Tue Oct 29 2024 An upper ridge builds across the area Tuesday through late week providing above normal temperatures with continued dry weather.
1223 AM CDT Tue Oct 29 2024 (Tonight through Tuesday night) Key Messages: A mid level high pressure system is forecast to track northeast across TX tonight through Tue morning as a deep long wave trough pushes southeast across the western U. This will lead to a tightening of the surface pressure gradient, thus strengthening S-SE winds in the lower levels. As the upper long wave trough approaches the region, a weak embedded short wave is progged to track N-NE across S TX on Tuesday. Despite the increase in moisture and the short wave, rain chances will remain low (10-24%) due to the moisture being confined to the lower levels.
As the trough moves east tonight, the associated cold front push will move southward across the state. Also the location of the low is favorable for upsloping on north and northeast facing slopes. This brings about a 24 hour period of tranquil weather before the next trough moves in off the PacNW coast. Models have decreased their similarities on where this trough goes, so forecast confidence the latter half of the week has decreased.
WAA and moisture return continues today ahead of the cold front tomorrow night, bringing record warm highs and lows. Highs will be in the low to mid 80s both days. (see climate section below) As the cold front passes through the area tomorrow night, showers and thunderstorms are expected (90-100% chance).
152 AM EDT Tue Oct 29 2024 Some showers Tuesday along the coast due to a coastal trough.
700 AM EDT Tue Oct 29 2024 High pressure builds in the next several days, with coastal troughing offshore. Warmer weather returns mid to late week.
539 AM EDT Tue Oct 29 2024 High pressure will move east of the region later today. A warm front will approach tonight then cross the area Wednesday.
632 AM CDT Tue Oct 29 2024 (Today through Wednesday) A large mid-level trough will continue to dig over Four Corners region then swing eastward into the Plains through the period. At the surface, low pressure develops across the Plains will allow the pressure gradient to strengthen along the Lower Texas Coast through the period.
356 AM MDT Tue Oct 29 2024 KEY MESSAGES: - Late-Week Cold Front: A colder system later this week is expected to bring snow to higher elevations and mountain passes. Model guidance indicates the trough over the Northern Rockies will slowly shift eastward on Tuesday, bringing continued mountain snow showers and scattered valley showers. There is strong agreement among models for a ridge of high pressure to build in, reducing shower activity on Wednesday.
205 AM PDT Tue Oct 29 2024 Cooler temperatures this week, with breezy north winds today.
850 AM EDT Tue Oct 29 2024 High pressure builds in the next several days, with coastal troughing offshore. Warmer weather returns mid to late week.
753 AM EDT Tue Oct 29 2024 (Today through Wednesday) Generally benign weather conditions will prevail across South Florida through the short term as an extensive area of high pressure sits over the southeastern US. Nevertheless, enough low level moisture, and some weak forcing provided by a weak upper-level trough dropping along the peninsula, may allow for isolated showers each afternoon. High temperatures will reach the low to mid 80s each day, with overnight lows in the upper 60s for the lake region, and the low to mid 70s over the Gulf and East Coasts.
700 AM EDT Tue Oct 29 2024 High pressure will move east of the region later today. A warm front will approach tonight then cross the area Wednesday.
Later tonight, the aforementioned high pressure system will still be centered east of our region. With sky conditions forecasted to be clear tonight, radiational cooling will occur allowing for nighttime temperatures to dip into the low 60s across our forecast area. Looking ahead into Wednesday, global guidance highlights a stronger upper-level trough pushing a closed low east across the Northern Plains along with an eastern ridge pattern.
After a dry, breezy, and mild day on Wednesday, Pacific weather systems then bring more periods of mostly light mountain snow and slightly cooler temperatures to close out the week.
(Today through Wednesday) Key Messages: - Small Craft Advisory for the bays and Gulf waters through Wednesday morning A deep trough will continue to progress eastwards during the day today as the mid level ridge that was influencing the area over the past few days transitions eastwards out of the area. The approaching trough is expected to tighten the pressure gradient over the region increasing winds to around 20-25 knots especially over the bays and nearshore waters.
Tonight may be the same, but we will need to see how far east this high moves.
355 AM MDT Tue Oct 29 2024 KEY MESSAGES: - Near normal temperatures, including lows below freezing, are expected through the end of the week. WEATHER PATTERN OVERVIEW: Upper trough will be moving through the northern Rockies and into the plains through mid week. Band of light rain over southeast Montana this morning will be pushed southeastward today with high pressure dropping out of Canada. A weak omega block develops briefly late in the week, with the current trough moving slowly across the Great Lakes and a second closed upper low spinning over the Pacific Northwest. Mid to high clouds will remain over the region through Wednesday morning as an upper trof moves across the state.
The highest chances (40-80%) are across southeastern and far eastern portions of the area. An upper level trough will pass through late Wednesday, bringing rain chances across the area briefly Wednesday evening, more likely across south central Nebraska (30-50%) than north central Kansas (15-25%). High temperatures today ahead of the front will range from the mid 70s to mid 80s, followed by much cooler weather Wednesday with highs ranging from the 50s across most of the area to the mid 60s across southeast portions of the forecast area. With an upper level ridge briefly passing through the area, dry weather is expected with highs in the 50s and 60s.
1027 AM EDT Tue Oct 29 2024 High pressure will continue to slowly meander offshore into the latter part of the week, with a steady warming trend ensuing.
627 AM EDT Tue Oct 29 2024 (Today and tonight) Our area remains entrenched in easterly to northeasterly flow on the southern side of high pressure. A plume of higher moisture will move in from the east later today, which may be enough for a shower or two to pop up this afternoon near the lower Suwannee Valley. Highs will be in the lower to middle 80s with mainly sunny skies. Another round of patchy fog will be possible near the I-75 corridor tonight, but otherwise a quiet night is in store with lows in the lower to middle 60s.
631 AM CDT Tue Oct 29 2024 An upper level ridge centered over the Southeast U.
- Widespread showers and embedded thunderstorms are likely Wednesday night along a cold front, which may feature some strong to severe storms.
1029 AM EDT Tue Oct 29 2024 A few showers are possible north of Pittsburgh this morning with a crossing warm front.
A cold low pressure system with brisk north winds and a few showers will move across our area today then pull away tonight. Cooler conditions will persist through the week with another weather system taking aim at the region by the weekend. The cold front that moved through the Las Vegas Valley between midnight and 1 AM this morning was quite strong as indicated by northwest winds gusting up to 55 mph at the North Las Vegas Airport and 54 mph at Nellis AFB. The cold pool associated with the broad trough will remain over Clark/Lincoln/Mohave counties today with sufficient moisture and for a few instability showers this afternoon over and downstream of the higher mountains.
We will see partly cloudy skies again today, as the center of an upper ridge will be over the region. Southerly winds will also be on the increase in response to a deepening trough across the Rockies that will bring us much needed rainfall later this week. Tonight into Wednesday, the upper ridge will slide east of the region ahead of the aforementioned Rockies trough, as it will be diving south towards the region with a cool front. Low-level moisture will continue to be on the increase with good southerly flow ahead of the trough/front.
633 AM CDT Tue Oct 29 2024 (Today through Wednesday) Key Messages: - Small Craft Advisory for the bays and Gulf waters through Wednesday morning A deep trough will continue to progress eastwards during the day today as the mid level ridge that was influencing the area over the past few days transitions eastwards out of the area. The approaching trough is expected to tighten the pressure gradient over the region increasing winds to around 20-25 knots especially over the bays and nearshore waters.
648 AM CDT Tue Oct 29 2024 (Today through Wednesday) Some light showers are noted early this morning from the middle Texas coast northward into portions of the Highway 77 corridor. An uptick in the low-level jet will also lead to another low chance for showers for the Hill Country eastward through the I-35 corridor and coastal plains beginning early Wednesday morning.
The PacNW will be in between systems today as the longwave trough axis exits to the east, leaving behind lingering mountain showers. Tonight will be drier with the transient ridge in place over the PacNW, returning more clear skies. Tomorrow morning will be remain dry as the ridge exits further eastward.
543 AM EDT Tue Oct 29 2024 A few showers are possible north of Pittsburgh this morning with a crossing warm front.
607 AM CDT Tue Oct 29 2024 (Today through Wednesday) High pressure remains over the Mid-Atlantic, resulting in east- southeasterly flow across the area.
pdf High pressure will stretch down the southeastern coast of the US early this afternoon, with an inverted trough over the coastal waters. The ridge is expected to move offshore later this afternoon, as the trough moves inland. Highs Today will range from around 80 at the coast, to the lower 80s inland.
