1056 AM EDT Thu Oct 31 2024 Morning low clouds and fog have thinned and lifted in most areas, but improvement has been fairly slow due to the persistent wedge and the high cloudiness spreading over the area from the upstream upper trough. This may limit the widespread development of low clouds, especially across areas where the higher clouds are more prevalent. Clouds ahead of the front will increase across the far north CWA tonight and this should keep the lower clouds at bay for the most part.
1001 AM EDT Thu Oct 31 2024 High pressure will bring unseasonably warm and mostly dry weather through Friday.
640 AM CDT Thu Oct 31 2024 (Today) A line of storms are ongoing this morning along and ahead of a cold front in SE OK and NW AR. The front and associated storms will likely push through the remainder of the CWA by 12z this morning with post-frontal high pressure filling in behind it. High temperatures today will be much cooler than the last several days.
651 AM CDT Thu Oct 31 2024 - Expect near normal temperatures today and Friday in the wake of a weak cold front. (Today and tonight) Early this morning, a surface cold front was moving south across southern portions of the forecast area. For the rest of the day, expect mostly sunny skies and cooler temperatures, with afternoon highs ranging from the low to mid 70s across the Big Country, to the lower 80s along the I-10 corridor.
Over the next three days, afternoon high temperatures are forecasted to be in the upper 70s to low 80s across the lower deserts and in the low-to-mid 70s across the higher terrain. Across the lower deserts, morning lows will be in the mid 40s to low 50s and in the typical cold spots will be near 40F. This weekend the aforementioned trough that is currently moving into the Pacific Northwest will start to make its way down into the southwestern US.
646 AM EDT Thu Oct 31 2024 (Today and tonight) High pressure north of Bermuda will continue to produce easterly flow across the area. Highs will be in the middle 80s with lows in the lower 60s.
527 AM CDT Thu Oct 31 2024 - A cold front and associated showers and storms will continue to move east and out of the area early this morning. - Cooler conditions will occur today and tonight as highs warm into the 60s and lows drop into the middle 30s to low 40s. A cold front and line of storms continues to move east across the area early this morning. A cooler air mass will move into the region today with highs warming into the 60s. Lows will drop into the middle 30s to the lower 40s tonight into Friday morning with the coolest readings occurring across central and south central Missouri. Highs will warm into the middle 60s to the lower 70s on Friday with the warmest readings across southeastern Kansas and far southwestern Missouri.
pdf High pressure will be centered to the northeast Today, with ridging extending southwest across the area. Weak troughing will pass through the onshore flow pattern, leading to the chance for a few sprinkles at the coast. Partly to mostly sunny skies this afternoon with highs in the lower to mid 80s.
620 AM EDT Thu Oct 31 2024 High pressure will bring unseasonably warm and mostly dry weather through Friday.
523 AM EDT Thu Oct 31 2024 High pressure will maintain dry and warm weather most of today. A band of showers is expected late today and tonight with a crossing cold front.
526 AM MDT Thu Oct 31 2024 - Temperatures have dropped below freezing for just about the entire CWA.
On-and-off again weather pattern to start the month as the short wave trough clears out this afternoon with another stronger trough system from the northwest moving over the state tomorrow evening, lasting through the weekend, bringing in much cooler temperatures along with some rain/snow mix. Today through Friday The short wave trough is expected to bring chances (up to 50-75%) of rain/snow showers north of the I-80 corridor and dissipate as the front moves east this afternoon. Friday starts of with calmer weather conditions under partly cloudy skies, seeing a slight increase in high temperatures in the 40s to 50s, however, another strong low pressure trough is expected to move over the state starting in the evening to overnight hours from the northwest, and moving southeast towards central Nevada.
Fair, breezy, and warmer weather is expected on Thursday and Friday ahead of a developing storm dropping south along the West Coast.
535 AM EDT Thu Oct 31 2024 High pressure will maintain dry and warm weather most of today. A band of showers is expected late today and tonight with a crossing cold front.
630 AM CDT Thu Oct 31 2024 - Cooler, more seasonal temperatures are expected through the period.
649 AM CDT Thu Oct 31 2024 (Today through Friday) Key Messages: - Coastal Flood Advisory extended through Thursday night A cold front will continue to drop southwards into central Texas today before eventually stalling.
The ridge dominating the southeastern CONUS is already being suppressed to the southeast as a strong s/w continues to move into the upper MS Valley. That said the ridge will hold pretty strong across the Gulf and into the Atlantic just off the southeast CONUS coast. This also is going to lead to the cold front approaching the area to really struggle to push south today and tonight with it likely hanging up and stalling over the Lower MS Valley just north of the CWA. Rain will continue to be possible across western portions of the CWA Friday but the eastern/southeastern half will struggle as the ridge tries to start rebuilding in from the southeast.
443 AM CDT Thu Oct 31 2024 (Thursday through Friday) A long-wave trough continues to push eastward across the Plains, dragging a cool front into the region. Rain chances will return over a good portion of the region on Friday, as the front is expected to slowly lift back northward as a warm front throughout the day.
A weak cold front and associated organized convective system currently moving through the Ozarks will move into northwest portions of the forecast area during the late morning hours, and then steadily push southeast to roughly the Natchez Trace corridor by the end of the day.
1052 AM EDT Thu Oct 31 2024 Unseasonably warm, Bermuda high pressure will extend across the Carolinas until a cold front moves through the region Friday night. Mild high pressure will follow and build across the middle Atlantic through the weekend. The strong ridge will dominate this afternoon as it continues to extend from the western Atlantic westward over the SE states. There will be subtle H5 height falls later today and tonight as the upper ridge slowly retreats south and the mid/upper trough moves through the Lakes. Highs will reach the lower to mid 80s. Lows will be 15-20 degrees above normal in the lower to mid 60s.
315 PM EDT Thu Oct 31 2024 Weak high pressure will linger across the region through the rest of this week.
(Rest of today through Friday) Generally benign weather conditions will prevail across South Florida today as mid-level ridging and an expansive area of high pressure sits over the southeastern US. 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.
1243 PM CDT Thu Oct 31 2024 A cold front will slowly move the Mid-South starting this afternoon and continuing through Friday evening.
Even with the passage of the cold front tonight, any cooler temperatures we get from it are going to be very short lived.
pdf High pressure will be centered to the east northeast through Tonight, with ridging extending southwest across region. Lows ranging from the lower 60s inland to the mid to upper 60s closer to the coast.
This system will likely weaken as it moves into our area due to high pressure in place.
223 PM EDT Thu Oct 31 2024 Warm and dry weather continuing into the evening before a cold front moves through tonight. Tomorrow is looking cooler and windier but staying dry for most of the region. Winds are expected to remain elevated through the evening as a cold front approaches from the west. With dry air in place, the cold front will struggle to maintain shower activity as it progresses west overnight, so the best chances of precipitation were kept across the Finger Lakes into CNY. Tomorrow will be breezy as a deepening low moves into New England and high pressure builds into the Great Lakes region, tightening the pressure gradient. Tomorrow night, lows fall to near freezing with continued cold air advection.
With strong lift in place, a few locations across the Buffalo Ridge in southwest Minnesota could see a couple of tenths to up to about a half an inch of snow. With cooler temperatures aloft in place, high temperatures will be near seasonable in the 40s to low 50s, warmest across central South Dakota.
Accumulations should be minimal due to surface temperatures and dewpoints above freezing and warm ground temperatures.
This will also allow for warmer overnight lows compared to widespread freezing temps that was observed this morning. Upper troughing will amplify across the western CONUS through tomorrow afternoon while also pushing eastward towards the Desert Southwest.
Slightly cooler than normal temperatures and quiet weather are on tap for the region today and tomorrow.
The latest observations and radar data show the surface cold front is exiting the CWA and will move into far SE MO and far southwest IL during the later part of the afternoon.
1249 PM CDT Thu Oct 31 2024 - Precipitation chances continue today, ending southwest to northeast throughout the day with cooler temperatures and windy conditions.
(Today through Friday) A cold front is beginning to stall out across central Texas as of 12 PM this afternoon with a wind shift evident ahead of the front, generally located along the northern border of our forecast area (Victoria to near Cotulla).
1217 PM CDT Thu Oct 31 2024 (Rest of Today) Line of showers/tstms ahead of oncoming cold front is approaching the MS River from the west this Thu morning. Ahead of the oncoming rainfall/cold front, cloudy skies have spread over most of the central TN Valley, as temps approach the 70F mark. Even with the increasing cloud cover, veering winds to the south near 10-15 MPH with gusts around 20-25 MPH may allow afternoon highs to reach the lower/mid 80s range for most spots.
Scattered instability rain and snow showers (snow level near 4000 feet MSL) will develop again later today as the upper trough moves through but amounts will be small.
130 PM EDT Thu Oct 31 2024 Unseasonably warm, Bermuda high pressure will extend across the Carolinas until a cold front moves through the region Friday night. Mild high pressure will follow and build across the middle Atlantic through the weekend. Stratocumulus clouds have developed and overspread much of central NC this afternoon due to the WAA flow around the periphery if the large high pressure centered just offshore. Expect dry weather to continue under the ridge this afternoon and tonight. Additional clouds from the cold front approach will arrive just prior to daybreak in the west, with possible sprinkles at that time.
This activity is in advance of a cold front that is located closer to the MS River. Temps this evening will fall into the 70s, before continuing to fall into the lower/mid 60s by early Fri.
(This evening through Friday night) A strong upper level ridge is centered just off the coast of the Carolinas and extended southwestward across much of the Gulf of Mexico. To the north, an upper level trough is racing northeastward across the upper Mississippi River Valley and will be moving across the Great Lakes tonight. This northeastward track of the trough will limit the associated cold front's ability to push much farther south than where it is right now in northern Louisiana. Due to the far proximity of the CWA from the upper trough, shear values will be way to low to support severe.
1213 PM CDT Thu Oct 31 2024 - A cold front and associated showers and storms will continue to move east and out of the area early this morning. - Cooler conditions will occur today and tonight as highs warm into the 60s and lows drop into the middle 30s to low 40s. A cold front and line of storms continues to move east across the area early this morning. A cooler air mass will move into the region today with highs warming into the 60s. Lows will drop into the middle 30s to the lower 40s tonight into Friday morning with the coolest readings occurring across central and south central Missouri. Highs will warm into the middle 60s to the lower 70s on Friday with the warmest readings across southeastern Kansas and far southwestern Missouri.
1235 PM CDT Thu Oct 31 2024 Latest surface observations indicate the cold front has pushed through the CWA and rainfall has ended for all locations. Mejia (Today) A line of storms are ongoing this morning along and ahead of a cold front in SE OK and NW AR. The front and associated storms will likely push through the remainder of the CWA by 12z this morning with post-frontal high pressure filling in behind it. High temperatures today will be much cooler than the last several days.
230 PM EDT Thu Oct 31 2024 Warm and dry weather continuing into the evening before a cold front moves through tonight. Tomorrow is looking cooler and windier but staying dry for most of the region. Winds are expected to remain elevated through the evening as a cold front approaches from the west. With dry air in place, the cold front will struggle to maintain shower activity as it progresses west overnight, so the best chances of precipitation were kept across the Finger Lakes into CNY. Tomorrow will be breezy as a deepening low moves into New England and high pressure builds into the Great Lakes region, tightening the pressure gradient. Tomorrow night, lows fall to near freezing with continued cold air advection. The weekend looks to stay dry as a small, weak ridge begins to build over the East Coast.
1206 PM CDT Thu Oct 31 2024 - Expect near normal temperatures today and Friday in the wake of a weak cold front. (Today and tonight) Early this morning, a surface cold front was moving south across southern portions of the forecast area. For the rest of the day, expect mostly sunny skies and cooler temperatures, with afternoon highs ranging from the low to mid 70s across the Big Country, to the lower 80s along the I-10 corridor.
However, scattered showers will continue behind this and along the cold front that is just now reaching the I-55 corridor. Auten For this spooky day, a cold front is making its way across central Illinois this morning, bringing welcome rain and some thunder. The cold front is actually displaced behind the precipitation and will finish moving through by early afternoon. They will begin to lessen as the cold front moves further away, since the pressure gradient will weaken as well. Behind the cold front, temperatures will become more seasonable. Highs will be in the 60s today, dropping cooler tomorrow.
238 PM CDT Thu Oct 31 2024 - Cooler conditions will occur tonight into Friday with closer to normal temperatures.
1229 PM CDT Thu Oct 31 2024 - Cooler, more seasonal temperatures are expected through the period.
(Through Friday) Subsidence from an upper ridge centered over eastern Florida will create a dry, unseasonably warm forecast through the rest of the week. High temperatures in the mid to upper 80s with low temperatures in the low to mid 60s expected.
(This evening through Friday Night) Cold front progression is beginning to slow as the boundary is bisecting the region, generally extending from near Magnolia, AR to Shreveport and farther SW near Nacogdoches and Lufkin, TX.
A stalled cold front across central Texas is helping pool moisture leading to showers along the coastal counties. As the stalled cold front in central Texas lifts tomorrow, it will take the mechanism forcing showers and leave the end of the short term period with low chances of rain.
Morning low clouds and fog have thinned and lifted in most areas, but improvement has been fairly slow due to the persistent wedge and the high cloudiness spreading over the area from the upstream upper trough. This may limit the widespread development of low clouds, especially across areas where the higher clouds are more prevalent. Clouds ahead of the front will increase across the far north CWA tonight and this should keep the lower clouds at bay for the most part.
Otherwise, high pressure is in place today, which will bring light winds for most areas along and west of the James River. An area of low pressure over Iowa is currently producing precipitation across southeastern South Dakota.
1224 PM CDT Thu Oct 31 2024 (Today and tonight) A much quieter day is expected today for the South Plains in the wake of a cold front early this morning. A short wave trough moving across the Intermountain West will induce surface cyclogenesis and pressure troughing in lee of the Rockies today. The ridge will then slide to the east in the afternoon allowing winds to swing back around to the southeast. Temperatures will be significantly cooler today under easterly upslope flow although still only close to average for Halloween.
GOES satellite imagery this afternoon reveals an elongated trough of low pressure extending from the British Columbia coast across the Pacific Northwest. The trough of low pressure will move inland tonight into Friday morning, bringing precipitation to north-central Idaho and the Idaho-Montana border, particularly in the Lower Clark Fork and Kootenai/Cabinet regions. Mountain snow showers and valley rain/snow showers will continue throughout the weekend as the trough axis moves through.
146 PM MDT Thu Oct 31 2024 KEY MESSAGES: - Near normal temperatures will generally persist through this weekend, with overnight lows occasionally dropping below freezing. WEATHER PATTERN OVERVIEW: The slowly-moving, slowly evolving flow aloft, through most of this week, shows signs of multiple blocking low centers and high centers. The blocking pattern begins to give way to a more progressive flow by later this weekend.
While rain is the favored precipitation type with this activity around and east of Billings, there is a moderate chance that a rain/snow mix occurs over the higher hills. There is a high chance the lower elevations and foothills see 0. Over the highest peaks of the Beartooth/Absaroka and Crazy Mountains, generally 1 to 3 inches of snow are expected. Over the highest peaks of the Bighorn Mountains, 0.
When compared to this time yesterday, the pressure gradient has decreased slightly, with only about a 8mb difference from the office to the center of the high. The ridge axis will continue to shift farther east as the flow flattens. As the flow amplifies again in a couple days, this will work to reinforce the ridge and keep the easterly flow locked in. The only noticeable adjustment is that the flow should veer a little more ESE starting late tonight and into the next few days as the ridge axis continues to shift.
Stratocumulus will surge northward Friday, the timing and height of which will be key to the high temperature forecast for Friday. Have trended toward the warmer side for now with the WRF-NAM looking a bit too aggressive in this regard.
The cold front will continue to move through the CWA late this afternoon/this evening with continued breezy conditions and mostly cloudy skies. Winds will also get lighter as high pressure begins to build into the region for the rest of the week. High pressure will dominate the CWA tomorrow into tomorrow night, resulting in mostly sunny skies tomorrow and another mostly clear night tomorrow night. Temps will be cooler tonight through tomorrow night (slightly below normal), with overnight lows in the 30s and a tomorrow afternoon high in the 50s. Auten The dry weather will not last long as the high pressure slides to the east and the weather pattern becomes southwesterly.
(Through tonight ) Cloud cover has for the most part exited far Southeast Oklahoma and Western Arkansas this afternoon with the departing cold front that moved through last night/early this morning. In the wake of the cold front.
Most of the precipitation will fall as rain, but some snow or freezing rain could mix in at times.
317 PM CDT Thu Oct 31 2024 Through Tonight: A cold front is progressing into the area bringing showers and isolated thunderstorms ahead of an upper trough. The trough will continue to struggle advancing southward with stubborn upper ridging deflecting it north and away. As a reminder, even light rains can result in reduced visibility ( particularly at night) and vehicle breaking can be dramatically less effective with even lightly wet road surfaces! With heightened outdoors activity tonight, extra caution is advised when driving in even marginally diminished conditions! /86/ Friday through Thursday: The frontal boundary sagging into our region today will continue to be a focus for showers or a few thunderstorms through the day Friday, with generally warmer and more unstable air south of the front. The pattern through the weekend will feature mid-level ridging over the southeastern U.
- Potential for freezing conditions will exist tonight through Friday morning, so a Freeze Warning is in effect for the lower central valleys where a widespread hard freeze still has not been reached.
What we do expect is a narrow cold frontal rainband that will move through the area between 300pm and 700pm. - Breezy with Few Showers and Storms This Morning, and Dry but Windy for Trick-or-Treating Southerly flow ramps up this morning as strong mixing occurs ahead of an approaching cold front. Aside from gusty winds, temperatures will be on the decline this evening during Trick-or-Treating time following the passage of the cold front.
Any precipitation would likely be rain although a brief period of freezing rain cannot be ruled out. Forecast soundings show a notable warm nose with surface temperatures below freezing. Any precipitation falling through this warm layer should help pull temperatures above the freezing mark (along with a quickly warming diurnal trend) with the primary precipitation being rain although wouldn't completely rule out a brief period of freezing rain/sprinkles around daybreak before temperatures can sufficiently warm. Ground temperatures well above freezing should limit impacts should any freezing precip occur. Fire danger west of I-29 where limited precipitation fell will rise into the high category.
- Expect near normal temperatures Friday in the wake of a weak cold front.
233 PM CDT Thu Oct 31 2024 - A strong cold front moves through the area this evening and tonight. - Cooler and dry tomorrow but this will be short lived. A band of showers continues to move east through the forecast area today ahead of an approaching cold front. The cold front moves through by tonight and will switch winds around to the north at around 5-10 mph. Brief high pressure quickly builds in behind the front. This will leave us cooler, drier, and clearer tomorrow, though it will be short lived.
123 PM EDT Thu Oct 31 2024 Rain showers return tonight ahead of a passing cold front. Gusty winds will continue across the area today, out ahead of an approaching cold front, which will bring a return of showers to the forecast area later tonight into Friday.
1110 AM CDT Thu Oct 31 2024 Latest surface observations indicate the cold front has pushed through the CWA and rainfall has ended for all locations. Mejia (Today) A line of storms are ongoing this morning along and ahead of a cold front in SE OK and NW AR. The front and associated storms will likely push through the remainder of the CWA by 12z this morning with post-frontal high pressure filling in behind it. High temperatures today will be much cooler than the last several days.
- Expect near normal temperatures Friday in the wake of a weak cold front. (This evening through Friday) Early this afternoon, the cold front that produced a few showers and storms last night was moving southeast through the Hill Country. Overnight, the high should move to the northeast, allowing southeasterly surface flow to bring a moist airmass back into the region.
