651 AM EDT Thu Oct 17 2024 Low pressure will slowly drift away from the coast today, while Canadian high pressure will expand from the middle MS Valley to the middle Atlantic through the end of the week. A potent mid/upper low is currently centered over NE NC. So temperatures in many spots are still in the lower-to-mid-40s, with one area of mid-to-upper-30s over the western Piedmont south of the Triad. The mid/upper low will move offshore and NE into the Atlantic today and tonight. High temperatures will be slightly warmer than yesterday but still below average, in the upper-50s to mid-60s. High-amplitude ridging aloft will move farther east towards the Eastern Seaboard, resulting in another day of sunny skies and increased temperatures with highs in the mid-to- upper-60s.
602 AM MDT Thu Oct 17 2024 Temperatures today will be much cooler, with highs mostly in the 40s and 50s. Much cooler today 2.
410 AM CDT Thu Oct 17 2024 - Strong winds today through the weekend ahead of a deep upper level low.
546 AM MDT Thu Oct 17 2024 KEY MESSAGES: - Cold front moving out of the region with light rainfall amounts. - Expecting gusty winds behind the cold front. WEATHER PATTERN OVERVIEW: Cold front has moved across the region overnight, with some increase in the winds. Cooler temperatures are expected today and Friday as the upper trough moves across the northern Rockies. Friday afternoon, the upper level low pressure trough axis stalls and slightly weakens right through eastern Montana, with a blocked/closed low pressure system developing over the Las Vegas/Flagstaff area, keep our location in NE MT in a nearly zonal flow.
622 AM CDT Thu Oct 17 2024 (Today through Friday) The most recent surface analysis from the Weather Prediction Center indicates a cold front draped across northern Mexico. Although dry weather will reign tonight, some isolated convection may return for Friday as broad, closed, mid-level low pressure moves into the Four Corners area. Temperature-wise, near normal values in the wake of the cold front today will warm to slightly above normal levels on Friday as cloud cover becomes more limited and an onshore flow redevelops. Finally, with churned-up seas along the Lower Texas Coast, a High Risk of rip currents and a Coastal Flood Advisory will exist at the local beaches for all or a portion of the period, respectively.
(Now through Friday night) An upper ridge extending from east Texas to south central Canada will shift eastward as the upper trough along the Eastern Seaboard moves out over the Atlantic. Lows tonight will range from around 40 degrees well inland to the lower 50s near the coast.
958 AM EDT Thu Oct 17 2024 A prolonged period of dry weather starts today as high pressure builds over the region.
742 AM EDT Thu Oct 17 2024 A prolonged period of dry weather starts today as high pressure builds over the region.
An area of high pressure has settled across the eastern U. High pressure is forecast to remain over the eastern U.
1155 AM CDT Thu Oct 17 2024 - 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 through next Thursday) A warmup will begin across the midstate in earnest tomorrow as an upper ridge builds over the eastern half of the country.
Temperatures end up a couple degrees warmer than today with most in the 70s and 80s along the river valleys. Behind the aforementioned disturbance will be a longer wave trough that will approach Friday night. Continued southeasterly flow brings in more low level moisture and keeps overnight lows on the warmer side in the 50s to low 60s areawide.
(This evening through Friday night) After starting our day in the 40s with exception to the southshore, we've made it all the way up into the low 70s. An exceptionally deep layer of dry air is entrenched on the backside of the strong long wave trough exiting the eastern CONUS spanning down the entire Mississippi River Basin and into the southeastern CONUS. With PWATs at daily record minimums and high pressure settling in across the eastern CONUS it's safe to say we're not getting much in the way of rain chances anytime soon.
As this high shifts eastward, the pressure gradient will weaken slightly, leading to a small decrease in wind speeds and a shift to east-southeasterly flow by tomorrow. However with PWATs at or slightly below normal, the overall rain chances will remain on the lower side. Highs tomorrow are forecast to reach the low to mid-80s, with overnight lows settling generally into the 60s. The main concerns during the short-term period are the high risk of rip currents and the potential for minor coastal flooding during high tide periods today and into the weekend.
1220 PM CDT Thu Oct 17 2024 No significant changes to the forecast this morning, An upper trough will continue to influence cooler and drier weather across the region today. Ridging aloft will build into the Lower Mississippi River Valley during the period. This, as high pressure at the surface remains over the region, while its center slides east of the forecast area. Heading into mid week, the ridging pattern is expected to flatten over the southeast.
155 PM EDT Thu Oct 17 2024 Canadian high pressure will build overhead tonight to bring frost and freeze conditions by Friday morning. 2) Freezing temperatures are expected by Friday morning west of the Blue Ridge, while areas of frost are expected to the east. Canadian high pressure will build eastward towards the Appalachian Mountains this evening and settle overhead tonight to start a long stretch of dry weather. Tomorrow morning is the real threat for freezing temperatures in the mountains and areas of frost in the Piedmont when light winds and clear skies will provide better radiational cooling. Subsidence will keep skies mostly clear, and daytime highs will start trending warmer each day, eventually closer to seasonal norms, in the upper 60s to low 70s.
(This evening through Friday) An upper level trough currently depicted over the Pacific Northwest region via water vapor imagery is expected to dig deep into the desert southwest region overnight. By Friday morning the center of the trough will become closed off from the main flow and park itself over the Four Corners region through the short term period which will work to cool temperatures and increase rain chances. Thunderstorms are expected to develop along the higher terrain in eastern NM this afternoon as a minor ripple in the flow aloft tracks through the region. However with the low expected to remain further west, we will see lack of instability and forcing for ascent over the South Plains region with the best chances being along a tight gradient of weak isentropic ascent across the western South Plains and far southwestern Texas Panhandle.
An amplified upper ridge builds over the Great Lakes tonight into tomorrow with the 700-500 mb anticyclone passing directly over Southeast MI Friday morning. Another chilly night is in store with lows settling into the lower to mid 30s. The sfc-850 mb ridge, now passing just south and east of the area, directs milder southerly return flow into the area tomorrow with 850 mb temps increasing from the 5. While the high stability prevents boundary layer mixing to that depth, high temps should take a step up to the mid 60s. Though the ridge axis will gradually become realigned near the mid- Mississippi Valley over the weekend, the upper height anomaly will remain parked overhead.
JPR A warming trend will begin today as high pressure settles over Middle Tennessee.
232 PM EDT Thu Oct 17 2024 Skies will become mostly sunny later this morning, as high pressure builds into the region. Aided by radiational cooling and less cloud cover, temperatures tonight will again drop into the lower to middle-30s. Will let the day shift reassess the needs for Frost/Freeze products, particularly if freezing temps this morning were widespread enough to call the growing season over for Luzerne and Lackawanna Counties. Fair weather and high pressure will continue on Friday, with temperatures rising up into the 60s, which is only a degree or two above normal. High pressure will bring clear skies, light winds, and a dry and warm airmass.
(This evening through Friday) An upper trough and closed low to our west will keep southwesterly flow across much of the area with some breezy south to southwesterly winds accompanying it. With ample low and mid level moisture overnight filtering into the area, expect low clouds to develop again overnight from the southwest to northeast and lows to dip into the low to mid 50s.
(The rest of this afternoon ) An elevated fire weather danger continues this afternoon as southeast winds gust to around 25 mph, with the highest gusts along and north of I-44 in northeast Oklahoma. Otherwise, another cool night expected with temperatures falling into the mid to upper 30s in the lower valley areas of southeast Oklahoma and across portions of northwest Arkansas.
Tonight will feature another night of temps in the low to mid 30s in many areas, although some areas are likely to remain around 39-42 for overnight lows.
Strong subsidence due to the high will keep the area sunny through sunset with temperatures this afternoon only in the upper 60s to near 70 degrees cooling into the 50s after by sunset north of I-10. Lows tonight under clear skies and high pressure will cool below normal to the low 40s inland and upper 40s to low 50s along the coast.
Temperatures this afternoon will continue to be seasonably cool, but will be generally 3 to 5 degrees warmer than yesterday as highs climb into the upper 60s and lower 70s. Mejia (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.
The latest surface analysis has high pressure situated across much of the CONUS. High pressure has kept mostly clear skies across the region but with low-level moisture in place, a stratocumulus deck has developed over portions of eastern Kentucky but not to the extent that it was yesterday. As limited cloud cover exists, temperatures have been able to climb into the upper-50s to low-60s which is on track for highs to be in the lower-60s for many places this afternoon. Overnight, clear skies and light winds are expected but with low-level flow out of the east-northeast; temperatures are forecast to be a little warmer with the aid of this flow direction and increased moisture. This combination will keep the area warmer overnight but widespread frost will still be possible; therefore, another Frost Advisory was issued.
1208 PM CDT Thu Oct 17 2024 (Rest of Today) Clear skies and calm winds allowed good radiational cooling to drop our temps into the low/mid 30s across the TN Valley this morning. High pressure will keep sunny skies overhead and light winds in place throughout the day.
(This evening through Friday Night) The region will remain sandwiched between a deepening trough to our west, and an expanding ridging to our east. Elsewhere, look for highs tomorrow to range in the low to mid-70s.
117 PM EDT Thu Oct 17 2024 A prolonged period of dry weather starts today as high pressure builds over the region.
(This evening through Friday Night) Easterly to northeasterly flow will continue to draw in cooler air through the overnight hours tonight, yielding another chilly morning for Southeast Texas.
114 PM EDT Thu Oct 17 2024 - Warmer today with highs in the low to mid 60s.
BB/03 (Now through Friday) An upper ridge extending from east Texas to south central Canada will shift eastward as the upper trough along the Eastern Seaboard moves out over the Atlantic. Lows tonight will range from around 40 degrees well inland to the lower 50s near the coast.
A cold front will bring showers to the area late tonight into Friday.
Clouds will be on the increase from west to east across the region on Friday leading to another day of fairly mild temperatures with highs ranging from the lower 70s to the lower 80s.
Issued 302 PM CDT Thu Oct 17 2024 Tonight and Friday: High pressure centered over the western Ohio River Valley will remain nearly stationary into the weekend. This large area of high pressure will influence much of the state, keeping conditions dry and quiet. With the gradual warming trend underway, both the overnight lows and high temperatures Friday are expected to be warmer than previously.
The large/strong surface to upper level ridge is now centered over KY/IN/OH and will slowly slide into the Mid-Atlantic states through Friday afternoon. The ridge has brought in a much cooler and dryer airmass as evident by the cool temps across the area Today. Most locations will get up into the lower to middle 60s today with some locations across north GA staying in the 50s. Temps will dip back down into the 30s and 40s tonight but not expecting temps to dip below the freezing mark. Temps will begin to rebound Friday with highs mainly in the 60s with some locations across central GA getting up into the lower 70s.
(Tonight) Mean troughing that was over the eastern Lower-48 much of this past week has finally moved to the NE, as upper ridging builds in from the SW. The higher heights and nearly unattenuated sun has helped to make for a milder day than yesterday, with temperatures so far warming into the mid 60s with mainly light winds. A storm system amplifying over the western states should result in a troughing west/ridging east setup over the CONUS over the weekend. However cool air was still in place, thanks to high pressure centered over the central Appalachians. This should result in the development of more frost, especially in those normally cooler spots.
KEY MESSAGES: - Widespread frost likely with freezing temperature favoring northwest PA and the higher terrain. ------------------------------------------------------------------- Under the influence of high pressure, the afternoon will feature a few diurnal cumulus clouds and plentiful sunshine that should return area temperature to only a few degrees below the daily average. The combination of clear sky, light wind and a cooler airmass is ripe for widespread frost development overnight tonight. The biggest uncertainty lies in the areal extent of sub-freezing temperature, which will be influenced by the degree of surface drying through the day as well as nocturnal dewpoint recoveries. Areas with highest confidence in widespread sub-freezing temperature were highlighted with the Freeze Warning while the lower confidence areas received a Frost Advisory.
A sprawling ridge of high pressure extending from Quebec southwestward to the western Gulf of Mexico will continue to be the dominant weather-maker across central Illinois through the upcoming weekend. With the ridge positioned just S/SE of the area, a light S/SE wind of 5-8mph is expected tonight, which will help keep the atmosphere lightly mixed. Barnes With upper ridging positioned over the Great Lakes/Ohio River Valley, the warming trend will continue right through the upcoming weekend.
Center of deep anticyclone will meander slowly from western Lower Michigan this afternoon to southwestern Ontario late tonight. Clear skies and calm winds have allowed overnight temperatures to drop into the lower 30s outside of the urban Metro area, which has likely resulted in areas to widespread frost development across SE MI. The first stronger wave of warm air advection coupled with extensive sunshine will allow temperatures to increase into the lower 60s today for a high.
118 PM MDT Thu Oct 17 2024 - Much cooler & wetter through Friday. 25" of precip, which may result in an additional few inches of snow (more over the highest peaks).
1217 PM CDT Thu Oct 17 2024 (Today through Friday) The most recent surface analysis from the Weather Prediction Center indicates a cold front draped across northern Mexico. Although dry weather will reign tonight, some isolated convection may return for Friday as broad, closed, mid-level low pressure moves into the Four Corners area. Temperature-wise, near normal values in the wake of the cold front today will warm to slightly above normal levels on Friday as cloud cover becomes more limited and an onshore flow redevelops. Finally, with churned-up seas along the Lower Texas Coast, a High Risk of rip currents and a Coastal Flood Advisory will exist at the local beaches for all or a portion of the period, respectively.
This is due to a strong high pressure to our north that will be sticking around through the weekend. This high pressure will start to modify causing our temperatures to rise slowly each day.
Low pressure is slowly meandering its way across the Northern Rockies this afternoon. Bundle up, skies will clear tonight and temperatures dive to the lower to mid 20s in many areas.
The first strong cold front of the season will move through tonight with widespread gusty winds expected along with shower chances grazing the southern Great Basin and northwest Arizona. Much cooler temperatures will follow for Friday with blustery conditions. Strong trough continues to push into the interior PacNW this afternoon, and will begin to drop south into the Great Basin this evening. This will send a sharp cold front southward after dark, with gusty southwesterly winds (especially downwind of terrain features) ahead of the front, followed but widespread gusty north winds behind the front, with gusts of 40-55 mph expected. With crashing snow levels associated with the cold front, light snow accumulations are possible in northern Lincoln County, generally above 5500 feet, by Friday morning.
High pressure has started to build back in across the region after last night's frontal passage. The southern extent of a longwave trough still extends across South Florida. This piece of the trough will begin to lift northward overnight as the parent low pushes further into the western North Atlantic. Have maintained the highest rain and thunder chances across the Straits and then tapered them off some towards the island chain.
Cold upper trough over our CWA is forecast to close off a low along the ID/NV border tonight, the low moving southward through eastern NV overnight. On Friday an upper ridge will come in from the west starting a warming trend, at higher elevations before lower elevations. Current Freeze Watch for early Friday morning looks more definite east of Boise, but less likely in the Lower Treasure Valley due to continuing northwest wind.
1250 PM EDT Thu Oct 17 2024 Skies will become mostly sunny later this morning, as high pressure builds into the region. Aided by radiational cooling and less cloud cover, temperatures tonight will again drop into the lower to middle-30s. Will let the day shift reassess the needs for Frost/Freeze products, particularly if freezing temps this morning were widespread enough to call the growing season over for Luzerne and Lackawanna Counties. Fair weather and high pressure will continue on Friday, with temperatures rising up into the 60s, which is only a degree or two above normal. With high pressure and a dry air mass sitting overhead, dry and slightly above average warm conditions are expected for the weekend.
We still anticipate afternoon highs to reach the lower to middle 70s. (Thursday through Friday) The early morning sfc analysis indicates strong ridging in place from the Mid-South SW into Cntrl TX. This ridging will persist through the day today, accompanied by larger scale ridging aloft noted on the water vapor imagery over the Cntrl CONUS, with a crystal clear sky giving way to strong insolation today.
It's windy and warm this afternoon with a very large ridge encompassing much of the eastern two thirds of the country. Temperatures continue to warm into the low 70s, with mid 70s to mid 80s toward central SD. Dew points have been slowly increasing, but not at the rate necessary to keep humidities from dropping further and those readings are now generally in the low to mid 20s. Winds continue to gust in the 30s, with a few 40s on the Buffalo Ridge. Mid level clouds will begin to overspread the area overnight with the approach of a cold front.
254 PM MDT Thu Oct 17 2024 KEY MESSAGES: - Rainfall associated with today's cold front will move into the Dakotas later tonight. - A few cool days and freezing nights will be followed by a rebound back to warmer temperatures later this weekend.
212 PM EDT Thu Oct 17 2024 * Frost is likely again tonight into tomorrow morning, with freezing temperatures possible in rural areas and river valleys. As a result, dry and mild weather will continue for the Lower Ohio. Visible satellite imagery have been depicting a small and brief layer of shallow cumulus across the Bluegrass and Cumberland where low-level saturation deficits are lower compared to further west where the high pressure center is. Rest of the afternoon and early evening will feature clear skies, light winds, and highs in the low to mid 60s. Also, near freezing temperatures could be reported in typical cold locations and along the river valleys, where instances of fog will also be possible.
(Rest of today through Friday) Most of South FL will see drier and cooler conditions today and Friday as a cold front remains in place across the Florida Straits. 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.
1144 AM CDT Thu Oct 17 2024 - Strong winds today through the weekend ahead of a deep upper level low.
612 PM CDT Thu Oct 17 2024 (The rest of this afternoon ) An elevated fire weather danger continues this afternoon as southeast winds gust to around 25 mph, with the highest gusts along and north of I-44 in northeast Oklahoma. Otherwise, another cool night expected with temperatures falling into the mid to upper 30s in the lower valley areas of southeast Oklahoma and across portions of northwest Arkansas.
A strong cold front will continue to progress through central Nevada this evening bringing showers and thunderstorms, graupel, gusty winds and rapidly falling snow levels. Impressive cold front with attendant band of showers and thunderstorms will continue to move through the area through tonight. The highest swath of wetting rains is expected across Lander and Eureka counties, eastern Humboldt county and Elko county where probabilities of reaching or exceeding one tenth of an inch are 90-100 percent.
638 PM CDT Thu Oct 17 2024 - Critical fire weather concerns will linger into the early evening hours as winds continue to gust over 40 MPH and RH levels remain in the lower 20% range.
* Frost is likely again tonight into tomorrow morning, with freezing temperatures possible in rural areas and river valleys. As a result, dry and mild weather will continue for the Lower Ohio. Visible satellite imagery have been depicting a small and brief layer of shallow cumulus across the Bluegrass and Cumberland where low-level saturation deficits are lower compared to further west where the high pressure center is. Rest of the afternoon and early evening will feature clear skies, light winds, and highs in the low to mid 60s. Also, near freezing temperatures could be reported in typical cold locations and along the river valleys, where instances of fog will also be possible.
dewpoints look to be slightly higher tonight compared to last night which will help low temps to be slightly warmer for most locations as well.
233 PM PDT Thu Oct 17 2024 There are scattered showers and a few isolated thunderstorms into early this evening for the higher Sierra.
