620 PM CDT Sun Oct 13 2024 (This evening through Monday) Today's cold front has had a little better surge than previously expected. The slightly cooler air mass in addition to light, albeit upslope, flow will promote good radiational cooling, although increasing mid and/or upper level cloud cover could limit that somewhat. Surface ridging begins to shift to the east of the forecast area on Monday with winds veering all the way to just west of south near the New Mexico line while off the Caprock winds will hang onto an upslope component much later into the day with cooler temperatures likely there closer to seasonal normals.
Lows tonight will likely fall into the low- mid 50s across southern portions of the area with 40s across NE OK & NW AR. (Through Tonight) The wind shift associated with the leading edge of a frontal boundary has just about cleared the area this afternoon, though the cooler air is lagging a bit behind the wind change. Slightly cooler conditions are noted north of I-40 where temperatures are holding in the low to mid 80s. High pressure will build in tonight, with overnight lows expected to be much cooler than previous nights. Overnight lows are forecast to range from the lower 40s across the north to the upper 50s along the Red River.
951 PM EDT Sun Oct 13 2024 * Breezy and turning much cooler tonight.
539 PM CDT Sun Oct 13 2024 (Through Tonight) The wind shift associated with the leading edge of a frontal boundary has just about cleared the area this afternoon, though the cooler air is lagging a bit behind the wind change. Slightly cooler conditions are noted north of I-40 where temperatures are holding in the low to mid 80s. High pressure will build in tonight, with overnight lows expected to be much cooler than previous nights. Overnight lows are forecast to range from the lower 40s across the north to the upper 50s along the Red River.
816 PM EDT Sun Oct 13 2024 Gusty winds this afternoon will be accompanied scattered showers and possibly a few storms along an north of the I-80 corridor this afternoon, followed by a broken band of convection crossing from northwest to southeast with a cold front. Cooler and unsettled weather is then expected through midweek under a trough of low pressure, followed by dry conditions and a warming trend later in the week. KEY MESSAGES: - Scattered showers and thunderstorms ending this evening ------------------------------------------------------------------- Current conditions across the area as of 7pm feature the cold front moving through eastern Ohio. After a lull in the precipitation after FROPA, additional scattered showers are expected to develop as this trough approaches. Much cooler temperatures are expected.
(Tonight through Tuesday night) Water vapor imagery this morning reveals upper level ridging stretching across the Southern Plains as an upper level trough digs across the Midwest. The upper trough will send a cold front south across the state early in the week. However, the low level moisture profile remains questionable for efficient fog production.
- A cold front will bring cooler temperatures this week. (Today and tonight) A weak cold front has moved through half the area this morning and will return east as a warm front tonight. As a result expect cooler temperatures today with highs ranging from 80 to 85 across the Big Country to the lower 90s along the I-10 corridor.
214 AM MDT Mon Oct 14 2024 - Near freezing temps early this morning. - Warmer temperatures return during the first half of the week, along with elevated fire danger. - Cooler and more unsettled late week. Then a change to wetter and cooler weather is expected for the second half of the week. Winds gusts anywhere from 5 to 20 mph are keeping temperatures from dropping to near freezing. The areas that are near or below freezing are all in wind-sheltered locations, such as river valleys. Another strong high pressure will slide southward from Canada to Minnesota and Iowa on Tuesday. The baroclinic zone, which will move eastward today, will slide back west on Tuesday, resulting in temperatures 5-10 degrees cooler than today.
438 AM EDT Mon Oct 14 2024 (Today through Tuesday) Highlights: - A cold front will usher in cooler and drier air to the area. A broad upper trough will continue to dig over the E half of the U. At the surface, a cold front across N GA will sweep S of the County Warning Area by this evening. This front will usher in drier and cooler air. As a result, relative humidity values will drop into the lower to mid 20s this afternoon, and a Fire Danger Statement has been issued for all but the extreme NE and S.
Partial clearing of cloud cover, light winds, and low level CAA will set the stage for freezing conditions.
By this afternoon, an inverted trough will shift west over Lake Superior, bringing light rain through the day, with up to half an inch of precipitation mainly near the lake.
1143 PM CDT Sun Oct 13 2024 - A cold front will bring cooler temperatures later this week. As of this afternoon, the cold front is moving through the northern Big Country. This along with the thermal ridge and clear, sunny skies have led to very above normal temperatures this afternoon. The high temperatures records for Abilene and San Angelo today are 97 and 102 respectively. The Big Country will see more of an impact from this front, with highs dropping into the low to mid 80s for tomorrow. Areas south of the Big Country will be a bit warmer, with highs in the upper 80s to lower 90s.
A weak area of low pressure will bring chances for showers to far northern Arizona today and on Tuesday. A stronger system then moves into Arizona near the end of the week, brining much cooler temperatures, gusty winds, and chances for preciptation to much of the region.
A trough/low complex will dominate much of the NE CONUS, with a long sfc front stretching across the S CONUS. This will keep an enlongated ridge in place across the GOMEX and the FL peninsula to start the work week. As the ridge axis gradually migrates ESE, it pushes a decaying sfc boundary into the FL straits, with a drier/relatively stable air mass descending upon SoFlo. For morning low, the Lake region and interior areas will cool down into the mid-upper 60s, while the coastal metro areas will remain in the low 70s.
1151 PM CDT Sun Oct 13 2024 - Strong northwest winds behind a cold front this afternoon will ease up a bit this evening, but remain gusty overnight (25 to 30 mph).
(Today through Tuesday) Tranquil weather is expected through Tuesday as high pressure aloft and at the surface remains in place. Highs today and Tuesday are expected to be slightly above normal with temperatures generally in the low to mid 90s under mostly sunny skies.
The low Monday morning will range from the upper 50s for areas east of the Chattahoochee/Apalachicola river basin, to the low 60s for areas to our west. (Monday night through Tuesday night) The anticipated cold front will be arriving into the CWA late Monday night into Tuesday morning. Much cooler and even drier air (PWATs less than 0. The temperatures will be in the upper 70s and low 80s for the high on Tuesday, with overnight lows cooling into the upper 40s/low 50s for Tuesday night.
1203 AM CDT Mon Oct 14 2024 (This evening through Monday) Today's cold front has had a little better surge than previously expected. The slightly cooler air mass in addition to light, albeit upslope, flow will promote good radiational cooling, although increasing mid and/or upper level cloud cover could limit that somewhat. Surface ridging begins to shift to the east of the forecast area on Monday with winds veering all the way to just west of south near the New Mexico line while off the Caprock winds will hang onto an upslope component much later into the day with cooler temperatures likely there closer to seasonal normals.
1154 PM CDT Sun Oct 13 2024 (Tonight through Monday night) Ridging remains in control over the region with dry and warm conditions persisting through the short-term. Highs will be warmer and mostly in the 90s tomorrow. Overnight lows will range from the low to mid 60s both tonight and Monday night, although Monday night will be slightly cooler.
1147 PM CDT Sun Oct 13 2024 (Rest of tonight) The main story tonight will be a cold front that is currently tracking southeast through Tennessee, producing a line of showers and thunderstorms to our northeast. Have kept PoPs on the lower side across far NE AL and southern middle TN due to the more limited convective environment, and have not really seen any trends in radar data to warrant raising PoPs or expanding further west. Winds will shift to the northwest behind the front, and strong cold air advection will occur as high pressure becomes the dominating factor.
AM EDT Mon Oct 14 2024 Warm weather expected until a cold front arrives later Monday.
342 AM EDT Mon Oct 14 2024 Cooler and unsettled weather is then expected through midweek under a trough of low pressure. KEY MESSAGES: - Precipitation chances will increase from the north after 4am with a sagging trough over the Great Lakes. Increase cloud coverage and cold advection will keep temperatures below average this afternoon, mid-50s for areas near and south of Pittsburgh, PA and upper-40s near I-80 and the higher terrain.
202 AM EDT Mon Oct 14 2024 Low pressure tracking across the Northeast will bring rain and cool temperatures to the region overnight.
236 AM EDT Mon Oct 14 2024 A cold front will move offshore today. Troughing will persist over the Mid-Atlantic through mid week.
Areas of frost will likely occur in far northern Kansas for a few hours around sunrise with temperatures in the low to mid 30s. Aloft, H5 analysis shows an amplified trough axis over Ontario with two areas of low pressure rotating around each other, and a closed low over the Great Basin. Highs are only expected to range from the low to mid 60s across the area this afternoon. An increase in wind will be observed Tuesday as that ridge builds south, and a rather chilly and dry air mass will advect into the CWA.
209 AM CDT Mon Oct 14 2024 - Much cooler and drier airmass will arrive for the first half of this week.
1233 AM EDT Mon Oct 14 2024 High pressure will prevail tonight. A strong cold front will push through the area later Monday, followed by cool and dry high pressure through late week. The upstream cold front will draw near the Appalachians, crossing the mountain chain late.
320 AM EDT Mon Oct 14 2024 - Colder and breezy conditions occur today on account of fall high pressure moving in from the northwest.
(Today) A cold front is quickly shifting south and east of the Tennessee Valley early this morning. A stark contrast in temperatures today as breezy NW/NNW winds will counteract the sunshine and reinforce this cooler, drier air mass that will be advecting into the region.
In the upper levels, a broad trough is rotating through the Great Lakes and eastern Canada, while a weak ridges sit over eastern Texas and the Atlantic on either side of Florida. At the surface, weak high pressure over the western Gulf of Mexico will slide east today and Tuesday, keeping a dry airmass in place across the forecast area with minimal rain chances.
1154 PM EDT Sun Oct 13 2024 Low pressure tracking across the Northeast will bring rain and cool temperatures to the region overnight.
As the low pressure slowly makes its way southeast across northern Wisconsin, cloud cover is starting to thin and showers are becoming more isolated in nature, especially for northeast Minnesota. Tonight, temperatures near to below freezing will lead to the possibility to more widespread snow showers throughout the Minnesota Arrowhead and inland portions of northwest Wisconsin. Highs in the low 50s and even high 40s are forecasted for Monday and Tuesday.
1109 PM CDT Sun Oct 13 2024 (This evening through Monday Night) Ridging aloft over the Desert Southwest should should keep conditions benign across SE Texas over the next few days. A weak, diffuse cold front is progged to enter SE Texas on Monday, though it's still expected to stall out over our northern counties.
(Today) Cold front has pushed south into the ArkLaTx region this morning with a few scattered mid/high cloud behind the front across E OK/NW AR.
1140 PM MDT Sun Oct 13 2024 - Warmer on Tuesday with another round of isolated mountain showers.
WV imagery indicates a northwesterly flow aloft prevailing across the Western High Plains downstream of weak ridging locked in across the Intermountain West. Near the surface, high pressure is drifting southeast through the Northern Plains. The drier trend is forecast to persist through mid-week as ridging aloft finally shifts east out of the Colorado Rockies into the Western High Plains. With a slow to erode cooler air mass, look for afternoon highs back up into the 70s(F) to near 80F Monday. A cold front is projected to push southward through western Kansas early Tuesday morning, allowing another surge of cooler air into the area. An area of high pressure at the surface will move across central Kansas overnight.
- A cold front will bring cooler temperatures later this week. (Today and tonight) A weak cold front has moved through half the area this morning and will return east as a warm front tonight. As a result expect cooler temperatures today with highs ranging from 80 to 85 across the Big Country to the lower 90s along the I-10 corridor.
Today's local upper air sounding illustrates winds backing to more SW'ly components in the lowest 2km AGL. The local high pressure regime will stay in place over the next few days through the early work week into Tuesday while broadening over Texas. Meanwhile a stronger longwave trof over Eastern Canada will slowly shift toward the NW Atlantic at the same time creating upper level speed convergence over the Midwest and Plains.
This will bring a chance of showers to the Ohio Valley Monday into Tuesday along with much cooler temperatures. An upper level trough axis will settle in across the Great Lakes region Monday into Monday night. Additional mid level energy rotating through the trough later in the day on Monday will lead to a few showers across our north. This will all be accompanied by a much cooler airmass. Energy pivoting through the H5 trough over the Ohio Valley will continue to provide chances for scattered showers throughout the day Tuesday.
Little change to our weather pattern is expected through midweek, as deep tropical moisture lingers over our region, but with synoptic forcing generally lacking as the lower-mid level ridge axis remains just to our south.
A shift to north to northeast winds will occur prior to 06z Tuesday as a cold front moves through. (Now through Monday Night) A large upper-level trough is beginning to dig into the Great Lakes region. Throughout the period, this trough will evolve into a massive upper low that will become centered over southeast Canada. At the surface, a ridge of high pressure that extends from the western Atlantic into the northern Gulf has allowed for a light southwesterly flow to develop across the area. For Monday, a cold front will begin to approach the area from the north. Lows in our northernmost zones will dip into the low 50s while locations along the immediate coast will only drop into the mid to upper 60s.
(Today through Tuesday Night) An upper ridge continues centered over the southwest U. An upper low continues in the northeast and will sink southward into the mid south by Tuesday night. With the cold front moving through northern Louisiana, Canadian high pressure will build into Arkansas. Ample sunshine will continue over the area today and Tuesday with much cooler temperatures. Highs today will be in the mid 60s to upper 70s and in the lower 60s to lower 80s Tuesday. Lows tonight will be in the low 40s to low 50s and in the low 30s to mid 40s Tuesday night.
(Today and tonight) The first of several cold fronts through the next few days passes through later this afternoon. Low temperatures tonight will be in the low to mid 50s across AL/GA and in the upper 50s across Florida.
- Expect cooler temperatures through mid-week as northerly flow ushers in cold Canadian air. Tonight and Monday Satellite and radar indicated an impressive upper low moving across Wisconsin this afternoon.
(Tuesday Night through next Monday) As we've been advertising for several days now, it's going to be cool today, but even cooler tomorrow as a reinforcing CP airmass makes its way through the region. The last time we saw a high of 65 or cooler at BNA was April 21.
1210 AM CDT Mon Oct 14 2024 (Through Tonight) The wind shift associated with the leading edge of a frontal boundary has just about cleared the area this afternoon, though the cooler air is lagging a bit behind the wind change. Slightly cooler conditions are noted north of I-40 where temperatures are holding in the low to mid 80s. High pressure will build in tonight, with overnight lows expected to be much cooler than previous nights. Overnight lows are forecast to range from the lower 40s across the north to the upper 50s along the Red River.
Dry and cooler today behind an exiting cold front. Discussion: A cold front is currently pushing across the area, noted by a sharp dewpoint gradient, clearing skies, and a wind shift. Advection of a cold, dry air mass will continue through the day behind the front, with a broad trough aloft providing a NW flow.
/Issued 229 PM PDT Sun Oct 13 2024/ High pressure over the region today is bringing clear skies to the area. The pattern will gradually transition Monday into Tuesday as the weather turns cooler and wetter and lingers through the remainder of the week.
(Today through Tuesday afternoon) After several hot days, a cold front has finally arrived. If you happen to be off for Columbus Day, get out and enjoy the "cooler" conditions.
117 AM EDT Mon Oct 14 2024 Low pressure tracking across the Northeast will bring rain and cool temperatures to the region overnight.
High pressure continues to move into the area this morning as some sites are still gusting to 20 kts as of 3 AM. West of this area, winds may stay up, but we should have more clear skies and could drop to near freezing. With the winds, widespread frost looks less likely, however with temps near freezing and some potential for frost, have issued a frost advisory for tonight.
Pattern Synopsis/Forecast: Expansive closed upper-level low pressure continues to circulate over the eastern half of Canada and the northeast CONUS early this morning. Pattern Synopsis and Forecast: Current midlevel pattern continues to push troughing southward into the Great Lakes region.
933 PM PDT Sun Oct 13 2024 An upper low will drift across Nevada and settle over Arizona continuing the cooling trend and deepening marine layer through Tuesday. The latter half of the week will feature a stronger Pacific storm system that will also track across the Great Basin bringing cooler and windier weather with a chance of showers for our region. The marine layer will deepen further since a closed upper low is over Nevada and will drop south through Tuesday. Further deepening will occur on Tuesday as the upper low settles over Arizona and cooling aloft occurs. The closed upper low will get kicked out of the Desert Southwest during midweek, ahead of a stronger Pacific system.
235 AM EDT Mon Oct 14 2024 Cooler and unsettled weather is then expected through midweek under a trough of low pressure. KEY MESSAGES: - Precipitation chances will increase from the north after 4am with a sagging trough over the Great Lakes. Increase cloud coverage and cold advection will keep temperatures below average this afternoon, mid-50s for areas near and south of Pittsburgh, PA and upper-40s near I-80 and the higher terrain.
(Today and tonight) Today will be noticeably for most areas thanks to yesterday's cold front. Highs are expected to reach into the low to mid 80s with a handful of locations possibly seeing highs in the upper 70s. Winds will south mostly out of the south through tonight as well ahead of another cold front that is expected tomorrow.
1118 PM EDT Sun Oct 13 2024 Cooler and unsettled weather is then expected through midweek under a trough of low pressure. KEY MESSAGES: - Precipitation chances will increase from the north after 4am with a sagging trough over Michigan/Lake Erie. After a lull in the precipitation after FROPA, additional scattered showers are expected to develop as this trough approaches. KEY MESSAGES: - Much cooler with scattered showers through Tuesday night ------------------------------------------------------------------- The trough is progged to deepen into a closed low across southeastern Canada Monday. A few snowflakes could mix in with the rain especially across the higher terrain areas of the Laurel Highlands and WV. Mixing and a strong pressure gradient between low pressure to our east, and high pressure to the west, will maintain wind gusts from 20-30mph through most of the period.
(Today through Tuesday) This AM, a cold front extended from SE PA, SWWD to W NC, back across NW AL, continuing back into NE TX and across the state. There will be a few clouds possible on Tuesday with the upper trough, but no precipitation is expected to accompany the trough.
1152 PM CDT Sun Oct 13 2024 (This evening through Tuesday) The CWA is currently right on the eastern fridge of a broad upper level ridge that encompasses the eastern western half of the country. An upper trough is draped over the rest/eastern half of the country. The increased heights from the ridge will keep highs on the warm side to start the week off. NBM suggests that temps will be a little cooler Tuesday afternoon as the trough to the east digs south and suppresses the ridge aloft. Do believe this may be overcome by compressional warming as cold front approaches from the north.
1147 PM CDT Sun Oct 13 2024 A dry cold front will move out the Mid-South overnight. Much cooler air will be in place over the region on Monday with temperatures some 15 to 20 degrees lower than this afternoon.
1057 PM CDT Sun Oct 13 2024 Updated at 1054 PM CDT Sun Oct 13 2024 - Reinforcing cold front expected Tuesday.
144 AM EDT Mon Oct 14 2024 Warm weather expected until a cold front arrives later Monday.
619 AM CDT Mon Oct 14 2024 (Today) A cold front is quickly shifting south and east of the Tennessee Valley early this morning. A stark contrast in temperatures today as breezy NW/NNW winds will counteract the sunshine and reinforce this cooler, drier air mass that will be advecting into the region.
607 AM CDT Mon Oct 14 2024 - Much cooler and drier airmass will arrive for the first half of this week.
Quiet weather with seasonable temperatures will continue into Tuesday as high pressure dominates and rather dry air holds on across the region. In the upper levels, a broad trough is rotating through the Great Lakes and eastern Canada, while a weak ridges sit over eastern Texas and the Atlantic on either side of Florida. At the surface, weak high pressure over the western Gulf of Mexico will slide east today and Tuesday, keeping a dry airmass in place across the forecast area with minimal rain chances.
The reason for this is the strong short wave that is dumping in the back side of the upper east CONUS trough causing it to stall or stand while this occurs. Both of these fronts will get a quick kick this morning as this short wave causes the long wave trough to dig south. For the most part, models are basically indicating the cloud field production brought about by the very warm waters destroying the low level inversion of the arctic air mass to transport moisture upward.
828 AM EDT Mon Oct 14 2024 Cooler and unsettled weather is then expected through midweek under a trough of low pressure. KEY MESSAGES: - Precipitation chances will increase from the north with a sagging trough over the Great Lakes. Increase cloud coverage and cold advection will keep temperatures below average this afternoon, mid-50s for areas near and south of Pittsburgh, PA and upper-40s near I-80 and the higher terrain.
