504 AM EDT Mon Oct 28 2024 A cold front continues to move south and west of the area, keeping cooler temperatures in place today. Upper ridging moves over the region, bringing a warming trend and dry conditions back to the area for much of the rest of this week. Through daybreak: Strong high pressure (~1028 mb) located over the Mid-Atlantic is bringing northeast winds to the area. Today and tonight: Strong high pressure centered over the Mid- Atlantic is expected to remain in place through tonight. These clouds are anticipated to start breaking up later this afternoon as mid to upper level ridging builds to our west, allowing for northwesterly flow aloft to aid in eroding some of this cloud cover.
351 AM MDT Mon Oct 28 2024 Expect cooler temperatures for the next several days as a Pacific cold front has moved through Central MT overnight. Accumulating snowfall is expected today through Tuesday in the higher elevations along the divide, along with areas around Big Sky and West Yellowstone. Cooler temperatures starting today across the entire CWA 3. Cooler air is moving into the CWA behind a Pacific cold front that moved through the CWA last night. Otherwise, afternoon temperatures will be on average about 20 degrees cooler than yesterday for most locations. The cooling trend continues into Tuesday, with most areas another 5 to 10 degrees cooler.
Snow levels have dropped to near 4,500'-5,000', so passes on the Cascades could be impacted as temperatures in the low 30s are present. As the trough passes today, temperatures will turn colder with temperatures on average 5-15 degrees colder than normal. Mornings begin in the 30s and 40s west side and near/below freezing east warming to 40s/50s west side and 40s east side. This passing trough will keep lingering showers through Tuesday morning near the Cascades and Coos and Douglas counties.
919 AM EDT Mon Oct 28 2024 Cool high pressure will prevail today with some showers tonight and Tuesday due to a coastal trough.
933 AM EDT Mon Oct 28 2024 High pressure will be in control of the weather for most of the week. A warm front moving through on Tuesday will bring some scattered showers in the afternoon.
945 AM EDT Mon Oct 28 2024 High pressure builds in the next several days, with coastal troughing offshore. Warmer weather returns mid to late week. Strong high pressure centered over New- England will continue to build southward into the Carolinas tonight, while coastal trough develops offshore. Developing trough will likely lead to a few showers offshore, possibly approaching the immediate coast late.

Today and tonight: Strong high pressure centered over the Mid- Atlantic is expected to remain in place through tonight. These clouds are anticipated to start breaking up later this afternoon as mid to upper level ridging builds to our west, allowing for northwesterly flow aloft to aid in eroding some of this cloud cover.
(Today through Tuesday) Key Messages: -Patchy fog expected this morning again across the Coastal Plains Areas of patchy fog has begun to develop this morning over the Coastal Plains as we are still under the influence of the mid level ridge located over Baja California. This will be due to the ridge to flattening out due to an approaching trough that will move into the western US today. Along the periphery of the ridge, there will be some mid-layer vorticity that will move into the region.
646 AM EDT Mon Oct 28 2024 Cool high pressure will prevail today with some showers tonight and Tuesday due to a coastal trough.
Cooler temperatures are expected by Tuesday with the potential for frost/freeze conditions to develop for interior areas. Model soundings are still showing modest instability and with the continuing upper level low we see a procession of frontal boundaries and post frontal activity through the week. Some of the interior ridges will again see some 20 to 30 mph gusts. A much colder air mass will arrive behind the cold front as we enter the coming work week. Low temperatures will reach frost and freezing levels this morning and especially Tuesday morning as a Freeze warning has been hoisted for interior Humboldt and Mendocino as well as Lake county.
559 AM CDT Mon Oct 28 2024 (Today through Tuesday afternoon) Upper level ridge that has kept unseasonably warm temperatures in the area is pushed eastward today. Wind increases will be due to the approach of an upper level low from the west.
649 AM EDT Mon Oct 28 2024 High pressure builds in the next several days, with coastal troughing offshore. Warmer weather returns mid to late week. Latest analysis shows high pressure centered over the Mid-Atlantic extending southward into the Carolinas. Strong high pressure centered over New- England will continue to build southward into the Carolinas tonight, while coastal trough develops offshore. Developing trough will likely lead to a few showers offshore, possibly approaching the immediate coast late.
617 AM EDT Mon Oct 28 2024 (Today and tonight) A backdoor cold front is moving through the area early this morning, bringing a low stratus deck in from the northeast. Typically, in these northeasterly flow regimes along the Appalachians, we tend to stay a bit cloudier for longer, and thus cooler than guidance would suggest. Lows tonight will be in the lower to middle 60s with some patchy fog near the I-75 corridor near daybreak.
This disturbance continues to fire off showers and thunderstorms along the western periphery of a mid and upper level ridge. The ridge's position is allowing for the cirrus to push up into our area.
(Today through Tuesday) Mid-level ridging in place will be pushed eastward thanks to a digging trough over western CONUS. As the trough approaches, the amplified pressure gradient will increase wind speeds as well as bring a more southerly flow. The once shallow layer of moisture is expected to deepen in the lower atmosphere throughout the short term period. NBM PoPs were quite low compared to other short term ensemble and deterministic guidance, therefore have blended the PoPs with HREF to increase PoPs along the lower Texas coast to ~20% for today. The cloud cover associated with increased moisture will keep temperatures a tad cooler than what has been the case for previous days, although highs will remain a touch above average for this time of year.
915 AM EDT Mon Oct 28 2024 High pressure will wedge southward across the Mid-Atlantic through at least Tuesday.
High pressure will continue to dominate the forecast pattern today. This will keep temps in NE AL a hair cooler than the rest of the forecast area today in the upper 70s. Overall, we will be unseasonably warm as upper level ridging builds in, the increase in heights will help daytime highs reach the lower 80s.

310 PM EDT Mon Oct 28 2024 Record breaking heat is expected tomorrow through Halloween under a strong ridge.
A small cluster is approaching the Lower Keys and may possibly bring up to a trace or a quick hundredth of an inch of rainfall. Otherwise, it has been quiet aside from the high cirrus streaming overhead. Temperatures have remained in the lower 80s with dew points rising a couple points into the lower 70s. High pressure in the northeast U. As the high slides further east across the Atlantic, the gradient will gradually lessen leading to breezes slackening to moderate to fresh.
213 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.
149 PM PDT Mon Oct 28 2024 Cooler temperatures this week, with breezy north winds tomorrow.
(Through Tuesday) The low stratus which filled in this morning behind a back door cold front is about done burning off for the day.
Transitioning into the overnight period temps will be very mild dropping into the lower 60s to upper 50s still well above climo. High temperatures tomorrow will be similar all be it a few degrees cooler from the morning low-level cloud cover. Heading into midweek a stronger western CONUS upper-level trough and eastern ridge pattern will set up.
The stratus deck that was parked over our south-central Alabama counties (associated with a weak, backdoor cold front) continues to erode at this hour.
345 PM EDT Mon Oct 28 2024 Clouds return tonight into tomorrow as a warm front approaches the region resulting in showers late Tuesday afternoon into the evening.
118 PM EDT Mon Oct 28 2024 High pressure will be in control of the weather for most of the week. A warm front moving through on Tuesday will bring some scattered showers in the afternoon.
Partly to mostly cloudy skies as a result of greater moisture will persist across the area, with temperatures climbing into the low to mid 80s this afternoon.
However, temperatures are forecast to be slightly cooler with moisture increasing across the area.
A weak lingering mid-level trough will gradually drop across the FL peninsula through Tuesday, as a strengthening ridge builds across the Eastern Seaboard. Tuesday should see a slight uptick in atmospheric moisture and forcing as the trough continues to drop over the area, leading to slightly higher chances for showers (15-25% PoPs) along the east coast. 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.
pdf Strong high pressure ridge will be in place across the southeastern US Today, with an inverted trough over the coastal waters.
A continued easterly flow in the lower levels will again help to support high humidity as temperatures cool overnight with more clouds and some patchy fog expected, especially near water features toward daybreak Tuesday morning. High temperatures will range from the mid 70s in the higher elevations east to the mid 80s far southwest.
WEATHER PATTERN OVERVIEW: As the main low pressure system moves through southern MT and northern WY, locations on the periphery and south of Fort Peck Lake have the best opportunity to see precipitation.
122 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. Meanwhile, heights are rising aloft as ridging shifts eastward in response to a digging trough across the western CONUS. The weather should be quite pleasant thereafter, with highs bumping up into the lower 70s.
1236 PM CDT Mon Oct 28 2024 (Today through Tuesday) Key Messages: -Patchy fog expected this morning again across the Coastal Plains Areas of patchy fog has begun to develop this morning over the Coastal Plains as we are still under the influence of the mid level ridge located over Baja California. This will be due to the ridge to flattening out due to an approaching trough that will move into the western US today. Along the periphery of the ridge, there will be some mid-layer vorticity that will move into the region.
Most of the cloud layer is below the freezing level, and lightning is still very unlikely.
228 PM EDT Mon Oct 28 2024 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.
308 PM EDT Mon Oct 28 2024 High pressure will prevail this week.
A large upper level high pressure ridge centered over the Southeast U.
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.
1233 PM CDT Mon Oct 28 2024 Near record high temperatures will persist through midweek as strong high pressure remains in place.
Upper troughing and area of low pressure is also noted across the Northern Plains.
122 PM EDT Mon Oct 28 2024 Cool high pressure will prevail today with some showers tonight and Tuesday due to a coastal trough.
308 PM EDT Mon Oct 28 2024 High pressure builds in the next several days, with coastal troughing offshore. Warmer weather returns mid to late week. By early tomorrow morning mid and low level moisture will increase as a coastal trough begins to pivot inland. Lows will range from the low to mid 40s inland to the upper 50s along the coast, with temperatures increasing after early tomorrow morning as clouds roll in. A coastal trough will push inland tomorrow as it weakens under a ridge of high pressure. By early afternoon, the trough will become more diffuse allowing skies to become partly cloudy, and temps will rise into the low to mid 70s for highs.
An incoming weather system will bring widespread gusty winds to the region today followed by cooler conditions and shower activity on Tuesday. Showers will mainly be confined to the higher elevations of Southern Nevada. Cooler conditions will persist through the week with another weather system taking aim at the region by the weekend.
Of course depending on how the lower levels evolve through the night there could be changes to the advisory. Going into Tuesday the low level flow begins to increase as the 1030mb high continues to slide eastward allowing for pressure gradient to tighten over the area. This would put the brakes on the fog potential despite increasing the lower level moisture.
The clouds sticking around into the afternoon have put a damper on the expected maximum temperatures today with some sites running a few degrees cooler, but we're still expecting to see temperatures at or above seasonal normals this afternoon. Once the sun does rise tomorrow we can expect to see much sunnier skies with temps climbing at least a few degrees warmer than what we experience today.
1140 AM EDT Mon Oct 28 2024 Record breaking heat expected tomorrow through Halloween under a strong ridge.
312 PM EDT Mon Oct 28 2024 Some showers Tuesday along the coast due to a coastal trough.
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.
The post-frontal air mass is notably cooler and temporarily more moist, resulting in some localized valley fog in places such as McCall. A cold front will slowly move through eastern portions of the area this morning/early afternoon as upper level troughing continues, bringing areas of MVFR/IFR conditions in showers and low clouds.
104 PM EDT Mon Oct 28 2024 Record breaking heat expected tomorrow through Halloween under a strong ridge.
122 PM MDT Mon Oct 28 2024 KEY MESSAGES: - Late-Week Cold Front: A colder system later this week is expected to bring snow to higher elevations and mountain passes. This Afternoon: Radar shows showers moving through the region as a trough of low pressure creates unstable conditions. Model guidance indicates the trough over the Northern Rockies will slowly shift eastward on Tuesday, bringing continued mountain snow showers and scattered valley showers.
1206 PM CDT Mon Oct 28 2024 (Today through Tuesday) The weak front is now well south of the area, with high pressure centered over the Mid-Atlantic. The low clouds should mix out by 10 AM and then sunshine will return with an easterly wind less than 10 mph. High pressure remains to our northeast through Tuesday so expect a easterly wind component through Tuesday and dry conditions.
The rest of today's forecast remains on track as a subtle cold front remains draped across parts of south-central Alabama (draped from northwest to southeast). Don't expect a massive difference in daytime temperatures on Tuesday as we still expect highs in the mid to low 80s - just a few degrees cooler than the past few days.
1201 PM CDT Mon Oct 28 2024 (Today through Tuesday afternoon) Upper level ridge that has kept unseasonably warm temperatures in the area is pushed eastward today. Wind increases will be due to the approach of an upper level low from the west.
646 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.
Boundary layer mixing will help dry out the lower levels bringing improved visibility along with gusty winds in the low to high teens by late tomorrow morning and afternoon. Transitioning into the overnight period temps will be very mild dropping into the lower 60s to upper 50s still well above climo. High temperatures tomorrow will be similar all be it a few degrees cooler from the morning low-level cloud cover. Heading into midweek a stronger western CONUS upper-level trough and eastern ridge pattern will set up.
722 PM EDT Mon Oct 28 2024 Some showers Tuesday along the coast due to a coastal trough.
Tuesday will be sharply colder, with temperatures Tuesday night likely freezing as low as 4000 feet. In addition, southwest winds have increased and are gusting in the 30 to 40 mph range across the high country. All this is in response to a narrow Pacific moisture tap ahead of a deepening west coast trough/cold front. The main cold front is still crossing central Nevada this afternoon and won't make it into Arizona until late tonight/early Tuesday. The cold front will move through the area Tuesday morning with the upper level trough and cold pool following. Very cold temperatures are in store Tuesday with highs in the 40s in the mountains and 50s to low 60s in the lower elevations.
