1222 PM CDT Wed Oct 16 2024 (Today through Thursday) The most recent surface analysis from the Weather Prediction Center indicates a cold front stretching from Houston to Austin to Dell City. However, another round of scattered showers and thunderstorms is anticipated for Deep South Texas and the Rio Grande Valley on Thursday as precipitable water values briefly increase in tandem with the passage of a 500 mb trough. Finally, with seas increasing along the Lower Texas Coast tonight through Thursday, a High Risk of rip currents will exist at the local beaches at least through that time period.
While it will be quite tough to get any fog development with how dry the air mass is, common locations near river valleys may see brief patchy fog develop, some of which may freeze and cause a few slick spots on bridges & roadways. Upper level trough will shift eastward Thursday with minor H5 height rises allowing for a very subtle upward trend in temperatures. High pressure will promote mostly sunny skies and a precipitation free forecast period.
(This evening through Thursday Night) In the wake of last night's cold front, skies are clearing out from north to south this afternoon, and this trend will continue on into the evening and overnight hours. Thursday will be mostly sunny to sunny and mild with highs ranging from the low 70s up north (in/around the Crockett area) to the upper 70s/around 80 down southwest (Wharton-Jackson County area). The weather stays quiet heading into Thursday night with low temperatures a little warmer, ranging from the low 40s up north (again, in/around the Crockett area) to the low to mid 60s at the coast.
BB/03 (Now through Thursday) A much cooler and drier airmass continue to move into the region this morning as strong high builds southward. High temps today will only climb into the low 60s across far northern areas to upper 60s to near 70 along the coast.
- Cold front arrives tonight from the west. - Expecting gusty winds behind the cold front. Of greatest concern is the wind associated with the passage of this cold front. Winds will be light and variable or light from the northwest ahead of the main push of the cold front.
A sprawling ridge of high pressure extending from Ontario to the Southern Plains will gradually settle southeastward tonight. Given the expected position of the ridge axis by dawn, the lightest winds and thus coldest overnight lows will be focused across the E/SE KILX CWA where readings will bottom out a few degrees below guidance in the upper 20s to around 30 degrees. Further west, temps will be a couple of degrees warmer in the 30-34 degree range. As the ridge axis shifts further E/SE, southerly boundary layer flow will develop across the entire area on Thursday. Barnes Upper ridging will build into the Midwest by the end of the week, resulting in a steady warming trend.
(Tomorrow through Wednesday) Southerly winds will strengthen across the area tomorrow as high pressure continues to slide east. Have issued a Fire Danger Statement for tomorrow for parts of NE OK as stronger winds are expected in these areas along with the low RH values already in place. Warmer temperatures will ensue tomorrow as well, with readings near or at seasonal averages for the weekend.
(Now through Thursday) Break out the sweatshirts and hot chocolate the first good shot of cold air has arrived! A rather large upper trough will continue to slowly lift northeast across the eastern US pushing cool dry air into the area. At the surface a strong cold front has pushed well into the Gulf. Temperatures will be the main talking point as lows tonight will drop into the low to mid 40s area wide.
110 PM EDT Wed Oct 16 2024 High pressure will build into the region from the west tonight. A ridge will continue building into the region this afternoon allowing for enough warming to start shutting off rain chances through this evening. Thursday night will feature high pressure becoming centered over the Ohio Valley with clear and dry conditions.
309 PM EDT Wed Oct 16 2024 A trough of low pressure will track east of the area tonight.
A upper level ridge begins to move over the region tonight, promoting increasing stability and drying low-levels through the rest of the day. This will promote afternoon highs in the low to mid 50s. The cool north-northwesterly flow over the warmer waters of Lake Huron will sustain low-level potential instability which will fuel rain showers chances along the tip of the Thumb and around the Lake Huron shorelines through the morning hours. Rain chances rapidly dwindle into the afternoon hours once an upper- level ridge folds into the state, strengthening mid-level subsidence and shrinking overlake inversion heights. As a reminder, frost or freeze products will not be utilized for the remainder of the cold season as the lower sun angle has ended the growing season.
Some areas may reach freezing. Under the influence of the high still Thu night will be another cool night of radiational cooling. The 500 MB pattern across the NOAM region will be dominated by a poleward shifted jet, mainly N of the intl border, and an overall sub-tropical ridge, with warm air, shifting N into the NE CONUS. Fri will be a transitional day as the the upper level trough finally shifts to our SE, with highs slightly above normal, in the mid 50s to low 60s under mainly clear skies.
(Through Thursday) Upper ridge will gradually build in from the west as troughing exits to the east through the near term forecast. At the surface, high pressure will continue to slide east while building further into the southeastern US. Tonight is expected to be quite cold with our inland areas seeing temperatures in the low to mid 40s as a cold air mass continues pushing into the southeastern US.
High pressure settles in Thursday promoting dry weather through the weekend. Overnight tonight, expect another cold night, particularly across much of the lower elevations, where less cloud cover and lighter winds can be expected. High pressure dominates the region through the weekend, with no precipitation or other hazardous weather expected outside of any patchy river valley fog and frost. Low temperatures Thursday night are expected to be at or below freezing across the board, with the exception being the southern coal fields where low temperatures will likely resist freezing and hover in the mid 30's.
305 PM EDT Wed Oct 16 2024 (This evening through Thursday) Current satellite loop shows mostly clear skies across the state with a few mid to high level clouds streaming in around the backside of the exiting low pressure system off the Mid-Atlantic coast. The models are showing a Surface to upper level ridge still building into the SERN U.
1243 PM CDT Wed Oct 16 2024 - Lows tonight into Thursday morning will be in the low to mid 30s.
1135 AM EDT Wed Oct 16 2024 * An upper level trough axis will move to the Mid Atlantic Coast this afternoon.
250 PM EDT Wed Oct 16 2024 High pressure will build into the region from the west tonight. A ridge will continue building into the region this afternoon allowing for enough warming to start shutting off rain chances through this evening. Thursday night will feature high pressure becoming centered over the Ohio Valley with clear and dry conditions. High pressure will be in control to end the week and start the weekend.
- Temperatures will be much cooler today with breezy conditions diminishing this afternoon. (Today and tonight) In the wake of the cold frontal passage yesterday evening and last night, much cooler air was moving into our area early this morning and accompanied by gusty northeast winds. After highs in the 90-95 degree range yesterday, temperatures will be much cooler today with mostly sunny skies. This to occur as the high pressure system over the Midwest moves east into the Ohio and Tennessee River Valleys.
Thereafter, temperatures will moderate as high pressure builds strongly across the Northeast at the surface and aloft.
- Temperatures will be much cooler today with breezy conditions diminishing this afternoon. (This evening through Thursday) The cold front that brought a much cooler and drier airmass into the area overnight is continuing southward into Mexico. Winds should turn out of the southeast overnight on the west side of the high, but should only be 5 to 10 MPH. Winds should turn more southerly and increase on Thursday which should advect some slightly warmer air back back into the region. Despite an increase in clouds, high temperatures should be in the upper 70s, which is about 5 to 10 degrees warmer than they were today.
Strong mid/upper ridge develops over the Great Lakes and East Coast with a pair of nearly-stationary upper lows across the southwest CONUS and Atlantic keeping the pattern stagnant. The next (very low) chance of rain arrives on Tue as ejecting upper low sends a weak cold front through the area. Progression of upstream low/mid level ridge axis and entrainment of much drier low level air/subsidence should allow the lake effect clouds to erode early this evening. West-northwest winds of 5 to 10 knots will become light and variable this evening, and then light southerly Thursday morning as the ridge slides off to the east.
1210 PM CDT Wed Oct 16 2024 (Today through Thursday Night) A relief from the heat, at last! A cold front is moving across SE TX and is currently extending near Bay City/Matagorda Bay per radar and satellite imagery. Surface observations in the past couple of hours have reported gusts from 20 to 35 mph with the higher gusts along the barrier islands/nearshore waters. This front will also leave us with cooler conditions. Temperatures will be 20+ degrees cooler than yesterday! Strong cold air advection will keep today's highs in the 70s to near 80 degrees. Light winds, mostly clear skies and surface dewpoints mainly in the 30s degF will result in temperatures into the upper 30s to mid 50s inland and into the low 60s along the coast. Cooler readings expected across the Brazos Valley and Piney Woods area.
1212 PM EDT Wed Oct 16 2024 Clouds decrease this afternoon as high pressure builds into the region.
959 PM CDT Wed Oct 16 2024 A quiet night still on tap across the Four State region, as high pressure will continue to build into the region overnight. This is due to a post-frontal air mass that has arrived behind troughing and an attendant frontal boundary that has crossed further into the Gulf of Mexico. Temperatures will remain much cooler than average for this time of the year with maximums/minimums in the upper 60s to lower 70s/40s to lower 50s, respectively.
A ridge of high pressure stretched north-south across central IL this evening. 25 A sprawling ridge of high pressure extending from Ontario to the Southern Plains will gradually settle southeastward tonight. Given the expected position of the ridge axis by dawn, the lightest winds and thus coldest overnight lows will be focused across the E/SE KILX CWA where readings will bottom out a few degrees below guidance in the upper 20s to around 30 degrees. Further west, temps will be a couple of degrees warmer in the 30-34 degree range. As the ridge axis shifts further E/SE, southerly boundary layer flow will develop across the entire area on Thursday. Barnes Upper ridging will build into the Midwest by the end of the week, resulting in a steady warming trend.
We are still expecting near or below freezing temps in those locations with patchy frost possible elsewhere. While it will be quite tough to get any fog development with how dry the air mass is, common locations near river valleys may see brief patchy fog develop, some of which may freeze and cause a few slick spots on bridges & roadways. Upper level trough will shift eastward Thursday with minor H5 height rises allowing for a very subtle upward trend in temperatures. High pressure will promote mostly sunny skies and a precipitation free forecast period.
Through the overnight hours high pressure center is progged to set up slightly farther east into eastern Arkansas. The normal cool locations across far eastern Oklahoma and northwest Arkansas could approach the freezing mark. With the lighter winds/cooler temps over far eastern Oklahoma and northwest Arkansas. (Tomorrow through Wednesday) Southerly winds will strengthen across the area tomorrow as high pressure continues to slide east. Have issued a Fire Danger Statement for tomorrow for parts of NE OK as stronger winds are expected in these areas along with the low RH values already in place. Warmer temperatures will ensue tomorrow as well, with readings near or at seasonal averages for the weekend.
1028 PM EDT Wed Oct 16 2024 High pressure building into the Northeast tonight will lead to the first widespread freeze of the season. This, combined with an already dry air mass in place, will result in ideal radiational cooling conditions and most areas will fall at or below freezing.
With clear skies and high pressure in place, good radiational cooling will occur overnight with morning lows falling into the middle 30s for most places, and a few spots in NE AL/Srn Middle TN dipping down around the freezing mark.
944 PM EDT Wed Oct 16 2024 High pressure will build into the region from the west tonight. A ridge will continue building into the region this afternoon allowing for enough warming to start shutting off rain chances through this evening. Thursday night will feature high pressure becoming centered over the Ohio Valley with clear and dry conditions. High pressure will be in control to end the week and start the weekend.
736 PM EDT Wed Oct 16 2024 An upper level trough axis will slide to the east.
828 PM EDT Wed Oct 16 2024 Quiet weather to remain in place through this weekend with high pressure in control. Key Message: 1) Freeze Warning in the mountains tonight and frost advisory east of the Blue Ridge. The faster this occurs, the better chance for widespread freezing temps. As high pressure settles in tonight, look for lighter winds and clear skies.
916 PM CDT Wed Oct 16 2024 Skies are clear across the Mid-South this evening with temperatures ranging from the lower 40s to mid 50s.
606 PM CDT Wed Oct 16 2024 - Temperatures will be much cooler today with breezy conditions diminishing this afternoon. (This evening through Thursday) The cold front that brought a much cooler and drier airmass into the area overnight is continuing southward into Mexico. Winds should turn out of the southeast overnight on the west side of the high, but should only be 5 to 10 MPH. Winds should turn more southerly and increase on Thursday which should advect some slightly warmer air back back into the region. Despite an increase in clouds, high temperatures should be in the upper 70s, which is about 5 to 10 degrees warmer than they were today.
715 PM CDT Wed Oct 16 2024 High pressure centered over southeast Missouri continues to dominate the weather pattern over Middle Tennessee this evening. (Thursday through next Wednesday) After the chilly morning on Thursday, continued dry weather with a gradual warmup is expected through the rest of the forecast period as an upper level ridge shifts eastward and builds over the eastern CONUS.
743 PM EDT Wed Oct 16 2024 High pressure will build into the region from the west tonight. A ridge will continue building into the region this afternoon allowing for enough warming to start shutting off rain chances through this evening. Thursday night will feature high pressure becoming centered over the Ohio Valley with clear and dry conditions. High pressure will be in control to end the week and start the weekend.
618 PM EDT Wed Oct 16 2024 - Frost or freezing temperatures are expected in most places by early Thursday morning.
635 PM CDT Wed Oct 16 2024 (This evening through Thursday Night) In the wake of last night's cold front, skies are clearing out from north to south this afternoon, and this trend will continue on into the evening and overnight hours. Thursday will be mostly sunny to sunny and mild with highs ranging from the low 70s up north (in/around the Crockett area) to the upper 70s/around 80 down southwest (Wharton-Jackson County area). The weather stays quiet heading into Thursday night with low temperatures a little warmer, ranging from the low 40s up north (again, in/around the Crockett area) to the low to mid 60s at the coast.
87/Grantham Previous short-term discussion: (This afternoon through Thursday) A strong ridge will be building over Central Alabama through the short term period while the upper-level trough moves east over the Eastern Seaboard.
(This evening through Thursday) Current satellite loop shows mostly clear skies across the state with a few mid to high level clouds streaming in around the backside of the exiting low pressure system off the Mid-Atlantic coast. The models are showing a Surface to upper level ridge still building into the SERN U.
706 PM EDT Wed Oct 16 2024 (Through Thursday) Upper ridge will gradually build in from the west as troughing exits to the east through the near term forecast. At the surface, high pressure will continue to slide east while building further into the southeastern US. Tonight is expected to be quite cold with our inland areas seeing temperatures in the low to mid 40s as a cold air mass continues pushing into the southeastern US.
557 PM EDT Wed Oct 16 2024 An upper level trough axis will slide to the east.
752 PM EDT Wed Oct 16 2024 High pressure building into the Northeast tonight will lead to the first widespread freeze of the season. As of 730 PM EDT, upper level ridging centered in the Midwest will build eastward tonight with northwesterly flow supporting dry and cold air advection. This, combined with an already dry air mass in place, will result in ideal radiational cooling conditions and most areas will fall at or below freezing.
Currently - A cold front is driving south southwestward through the Keys resulting in sharply freshening northeasterly breezes. 5 inches with significant drying through the lower levels. This is due to the expected remoistening of the lower levels and development of some isentropic lift. Expect overnight lows to be in the lower to mid 70s with dew points likely slipping into the mid to upper 60s. A powerful high centered over the southeastern United States will drive a cold front southward through Keys waters over the next few hours. (00Z TAFS) A cold front driving southward through the Keys this evening will result in north to northeast breezes strengthening substantially.
142 AM EDT Thu Oct 17 2024 (Through Thursday) Upper ridge will gradually build in from the west as troughing exits to the east through the near term forecast. At the surface, high pressure will continue to slide east while building further into the southeastern US. Tonight is expected to be quite cold with our inland areas seeing temperatures in the low to mid 40s as a cold air mass continues pushing into the southeastern US.
A cold upper level trough axis will move east through Friday, while a large ridge of high pressure at the surface will then builds into the state and sets up residence for several days.
(Today through Friday) A cold front continues to slowly push south early this morning and should settle across the Florida Straits today and remain in the vicinity through Friday. Meanwhile, strong high pressure is building in to our north. Most of South FL will see dryer and cooler conditions today and Friday, with just a slight chance of some showers over the far southern tip of the peninsula. Low temps tonight will range from the lower 60s around the lake to lower 70s across the east coast metro. High temps on Friday will be a couple degrees warmer but remain below normal with lower 80s for most.
- Drier and warmer conditions are expected through the weekend. No changes were made to the Freeze Warnings or Frost Advisories as temperatures away from the city and the lakeshore are expected to approach or fall just below freezing before daybreak.
(Friday Night through next Thursday) After Friday, a warm-up is in store as upper ridging and southeasterly boundary layer flow take over the region.
For the meantime, ridging slides into the Great Plains, supporting a shift to southeasterly winds under continued clear skies. Temperatures should be a touch warmer, mainly into the 70s. Lee troughing comences in earnest in response to this feature. Lee troughing is maintained heading through Friday, pushing dewpoints to near 60 degrees across the region. Clouds, especially across the lower elevations limit daytime heating somewhat, but expect temperatures to climb a couple degrees over Today.
(Today and tonight) Upper low over the Outer Banks of NC today, while troughing deepens over the western U. This places us beneath a fairly narrow but stationary ridge of high pressure that will produce fair and dry weather. Temps running around 7 degrees below normal today, but at least will be a little bit warmer during the day today than yesterday.
This is all thanks to the broad scale upper level trough across the eastern US. At the surface, high pressure continues to drop southward into the mid MS River Valley. The upper level pattern begins to evolve going into tonight and especially into Friday as the upper trough becomes replaced with some weak ridging.
Issued 338 AM CDT Thu Oct 17 2024 Today through Friday: Mostly sunny skies and breezy southerly winds are expected today and Friday between high pressure centered to the southeast and a trough moving over the ridge from the northern plains into Canada.
347 AM EDT Thu Oct 17 2024 High pressure will settle over the Ohio Valley today and Friday before slowly drifting east into the eastern United States over the weekend. Light winds and radiational cooling will allow temperatures to drop into the low to mid 30s again tonight. Locations along the immediate lakeshore will remain in the warmer upper 30s to around 40 degrees overnight so northern Erie PA, Ashtabula, and possibly Lake counties could avoid frost/freeze headlines. Temperatures continue to recover Friday with highs in the low to mid 60s anticipated. High pressure in control through the short term period.
(Today) Light winds have allowed many locations to fall near or slightly below freezing this morning, especially sheltered valleys of western AR and southeast OK where Frost Advisory remains in effect early this morning.
1232 AM PDT Thu Oct 17 2024 A robust cold front will progress southward through Northern and Central Nevada today into tonight. Today through Friday night A strong cold front will move southward across Northern and Central Nevada today into tonight. An upper-level area of low pressure will develop near the Nevada/Utah border early Friday morning. This cyclone aloft will progress southeastward into the Desert Southwest Friday afternoon and Friday night. Isolated thunderstorms may develop along of and ahead of the aforementioned cold front in Southern Elko, Southern Humboldt, Northern Eureka, and Lander Counties. High temperatures this afternoon will be around fifteen degrees cooler than yesterday afternoon.
1203 AM CDT Thu Oct 17 2024 High pressure centered over southeast Missouri continues to dominate the weather pattern over Middle Tennessee this evening.
Currently there's a mid-level low over the eastern seaboard, high over the Southern Plains and a deepening trough over the Pacific NW. The pattern progresses eastward with the aforementioned trough developing a low that digs in across the Desert SW by the weekend. There's a low (15%) chance for showers across the Rio Grande Plains today followed by a low chance for showers expanding across the region Friday as troughing in the vicinity remains through the short- term accompanied by the increased low-level moisture.
After a few nights of particularly cold and below-normal low temps, frost to near-freezing condns look to subside, w/ overnight lows trending upwards to the upper 30s to low 40s the next few nights.
Through the overnight hours high pressure center is progged to set up slightly farther east into eastern Arkansas. The normal cool locations across far eastern Oklahoma and northwest Arkansas could approach the freezing mark. With the lighter winds/cooler temps over far eastern Oklahoma and northwest Arkansas.
