1015 AM EDT Thu Oct 19 2023 Low pressure tracking east across the Upper Great Lakes today into Friday will push its southward trailing cold front slowly east across the state during the day Friday. Several rounds of showers will precede and accompany this front and a few thunderstorms could even develop across the Lower Susq Valley later Friday afternoon and evening in the mild and moist airmass ahead of the frontal boundary.
(Rest of Today) Currently, surface observations indicate that temperatures are mainly in the lower to mid 50s across the Tennessee Valley.
609 AM CDT Thu Oct 19 2023 (Today through Friday night) Today and Friday will see ridging pass across the region bringing fair weather and light winds to the panhandles. This ridge will cause abnormally hot temperatures across the panhandles for both days with Friday seeing the zenith of the heat. However the majority of the panhandles should be slightly cooler remaining in the 80s.
Otherwise, evidence of the cooler fall weather we were enjoying is eroding as temperatures this morning are already near 80 degrees with dew points near 70 degrees making it a little muggy.
612 AM CDT Thu Oct 19 2023 (Today) A weak and subtle cold front continues to push through the TSA CWA early this morning. Slightly cooler high temperatures -- low-mid 70s -- are expected across far NE OK and far NW AR.
(Today through Friday) A pre-frontal trough currently in the Hill Country will move south into the northern Brush Country and Victoria Crossroads by this afternoon then push south of the area by tonight, turning weak winds to the north. Temperatures today will reach the mid 80s to near 90 across the area today with temperatures reaching into the low 90s for Friday.
(The rest of today ) Deep upper trough in the Great Lakes region resulting in dry NW flow aloft today.
604 AM CDT Thu Oct 19 2023 (Today through Friday) A pre-frontal trough currently in the Hill Country will move south into the northern Brush Country and Victoria Crossroads by this afternoon then push south of the area by tonight, turning weak winds to the north. Temperatures today will reach the mid 80s to near 90 across the area today with temperatures reaching into the low 90s for Friday.
843 AM EDT Thu Oct 19 2023 Dry and warmer weather is expected today as high pressure exits the East Coast. Rain returns this evening through Friday night with the approach and passage of a cold front.
530 AM EDT Thu Oct 19 2023 Dry and warmer weather is expected today as high pressure exits the East Coast. Rain returns this evening through Friday night with the approach and passage of a cold front.
602 AM CDT Thu Oct 19 2023 Scattered showers will spread across the Mid-South today as a cold front moves across Arkansas. The cold front will cross the Mississippi River tonight with more showers and a few thunderstorms possible.
Upper ridging will be the trend through the period, as 700mb temps warm to around 15C on Friday.
238 PM MDT Thu Oct 19 2023 A cold frontal passage tonight will bring about breezy conditions across NE Montana. VFR conditions tonight are expected with breezy conditions possible at times with a cold frontal passage.
However, here to ruin our wonderful conditions, is a digging trough over the Midwest bringing a cold front through the region late tonight into tomorrow morning. Given the moisture, and large scale ascent supplied by the trough, we may see an isolated shower or two for the higher elevations of North GA as well as parts of West Central GA this afternoon. The main show comes later with the cold front. The highest QPF is currently over the mountains of north GA and into TN, with values near 0. Temperatures behind the front will not be significantly cooler than current conditions.
Issued by National Weather Service Lake Charles LA 101 PM CDT Thu Oct 19 2023 (Today through Friday) Upper ridging centered over the Appalachians and over Nevada this morning with a sharp trough running from the Great Lakes to the Iowa-Illinois border to north Texas. At the surface, high pressure extended along the Atlantic Coast into the northeast Gulf of Mexico. Low pressure over Wisconsin had a cold front to near Kansas City into north Texas. The upper trough to our northwest will push across the area later this afternoon and evening. It gets increasingly difficult to find a legitimate frontal boundary across the local area with the passage of the upper trough. NAM/ECMWF guidance is generally 3-5F cooler.
- Much above normal temperatures Friday with cooler temperatures arriving behind a cool front this weekend.
250 PM MDT Thu Oct 19 2023 Current surface analysis shows low pressure over the western Great Lakes region, with a trough to the west of the area.
328 PM EDT Thu Oct 19 2023 Low pressure will track through the Great Lakes and an associated cold front will swing through the region overnight resulting in widespread rain showers through Friday morning.
Mid-level ridging will move eastward tomorrow and winds will begin to shift back to the south. Temperatures are expected to warm up into the mid 80s tomorrow afternoon for most locations, and into the low 90s for southwestern Oklahoma and western north Texas.
With an upper ridge/northwest flow over the region again tomorrow expect conditions for temperatures to exceed to remain. A dry cold front will move through the region.
Clouds will then increase as the day wears on from west to east as another low pressure system approaches from the west.
1206 PM CDT Thu Oct 19 2023 (The rest of today ) Deep upper trough in the Great Lakes region resulting in dry NW flow aloft today.
1202 PM CDT Thu Oct 19 2023 (Today through Friday Night) A spy with my eye a front! But is it a 'real' cold front? Eh. The lower humidity will once again allow evening and overnight temperatures to drop quickly on Friday night with lows in the upper-50s to low-60s.
203 PM EDT Thu Oct 19 2023 Low pressure tracking east across the Upper Great Lakes today into Friday will push its southward trailing cold front slowly east across the state during the day Friday. Several rounds of showers will precede and accompany this front and a few thunderstorms could even develop across the Lower Susq Valley later Friday afternoon and evening in the mild and moist airmass ahead of the frontal boundary.
222 PM CDT Thu Oct 19 2023 A cold front moving through the region today will switch winds around to northwesterly. The upper level energy associated with the trough is primarily to our northeast, however one additional lobe will slide southeast later today into tonight. Temperatures will be slightly cooler tomorrow, on the order of 1 to 4 degrees.
1215 PM CDT Thu Oct 19 2023 (Today through Friday) An overall dry day is expected as a cold front begins to approach the area. A pre-frontal trough is out ahead of the front and stretches from Michigan to Arkansas. High pressure is centered over the Mid- Atlantic. The pre-frontal trough will make it into the northeast by the afternoon, but will lose moisture as it moves through the area and encounters the western edge of the high pressure. So any rain with the trough will be limited to the north and northwest through the afternoon. The cold front itself will move into the northwest near sunset and then move through overnight.
(This evening through Friday) Mostly sunny skies and light winds will persist through today with highs in the low-to-mid 80s across the forecast area. Temperatures will continue to increase Friday as an upper ridge currently centered over the Mountain West shifts eastward and surface winds turn more southerly.
(Tonight) A deep upper trough is expected to traverse the Ohio Valley, Tennessee Valley, and Deep South tonight. Meanwhile, a surface cold front is also slated to progress over the Tennessee Valley. Low temperatures are forecast to merely dip into the lower to mid 50s for most areas due to cloud cover and increased chances of precipitation.
1254 PM PDT Thu Oct 19 2023 Warm weather persists through the end of the week until much cooler temperatures arrive over the weekend.
Currently have a pronounced trough extending from the Great Lakes region down into the Tennessee Valley. Meanwhile, upper ridging extends from the Central Great Basin into the Desert Southwest. At the surface, low pressure is situated over the Western Great Lakes with ridging over the southern High Plains. For tonight through Fri, northwest flow aloft will remain over the Plains with ridging through the Desert Southwest.
155 PM MDT Thu Oct 19 2023 High pressure in control will result in clear skies and light winds with unseasonably warm temperatures during the day and seasonably cool temperatures at night. Near record warmth and dry weather will continue through the weekend under the influence of a strong ridge of high pressure.
1251 PM CDT Thu Oct 19 2023 (Today through Friday) A potent low pressure system works into the Great Lakes and deepens the mid level trough across the eastern CONUS into the weekend. This strengthens the mid-level ridge of high pressure in control across Texas and brings additional dry air into Friday. Light downsloping winds are expected by late this morning across the lower RGV, so have leaned toward higher guidance. A potential limiting factor would be some of the higher clouds streaming across the region from Hurricane Norma in the EastPac.
1215 PM CDT Thu Oct 19 2023 (Rest of Today) Currently, surface observations indicate that temperatures are mainly in the lower to mid 50s across the Tennessee Valley.
Temperatures appear on track, with lows in the low 40s NW to upper 40s east and SE. Friday, mostly sunny skies and NW winds of 10 to 20 MPH are expected as a ridge of high pressure moves across the area. High temperatures will be seasonal, with readings in the lower 60s NE to upper 60s SW.
(Tonight through Friday night) Other than few to scattered high clouds moving from west to east across the Lower Valley and a few low clouds pushing north from the Matamoros area, sunny skies are in place across the rest of the Deep South. Southerly winds continue across the local area and even become lighter and variable tonight into Friday as a cold front stays just to the north of the Northern Ranchlands. Overnight lows are forecast to range from the low 60s across the Brush Country to low 70s across the Lower Texas beaches. In addition to warmer lows areawide, there is the possibility for patchy fog across the Lower to Mid Valleys but not limited to those areas. Well, Friday is going to feel like summer time with highs reaching the low to mid 90s everywhere.
/Issued 240 AM PDT Thu Oct 19 2023/ An upper level ridge continues to influence conditions across northern California and southern Oregon.
High temperatures on Friday will climb back into the lower 80s, around 20 degrees above normal. The flow aloft will be slightly weaker as the ridge axis shifts over CO.
- Warmer temperatures briefly return tomorrow with gusty winds.
Until that happens, it will be another mild day with most areas reaching the lower 70s. The line of showers and storms will move off the Plateau prior to midnight but additional showers are possible through Friday morning as a lobe of energy moves through troughing. Rain chances will shut off by Friday afternoon as the large scale trough axis moves east of the area.
(This afternoon through Friday) The cold front is arriving with a SW wind shift to NW for Idabel just this past top of the hour. It is 70 degrees there and could tack on another 10 degrees for the high temp. Other locales are already in the low to mid 70s ahead of the front with perhaps even a touch of compressional heating on tap for the mid afternoon NW wind shifts down our I-49 corridor. One area of clouds has cleared our parishes east of I-49 and the cold front is gathering some more mid and high clouds over NE TX at this time.
/Tonight through Thursday/ FORECAST HIGHLIGHTS: --Gradually clearing and slightly cooler tonight.
A deep upper trough is shifting east of the Mississippi River, with an embedded PV max moving into IN attm. At the surface, low pressure was centered over Lakes Superior and Michigan, with a trailing cold front extending south and west from the low down into the ArkLaTex. As the upper trough slides farther away from us, an expanding low level thermal ridge over the Plains will yield warming temps back into the 80s most areas.
1251 PM CDT Thu Oct 19 2023 (Today through Friday) A pre-frontal trough currently in the Hill Country will move south into the northern Brush Country and Victoria Crossroads by this afternoon then push south of the area by tonight, turning weak winds to the north. Temperatures today will reach the mid 80s to near 90 across the area today with temperatures reaching into the low 90s for Friday.
1221 PM CDT Thu Oct 19 2023 Scattered showers will spread across the Mid-South today as a cold front moves across Arkansas. The cold front will cross the Mississippi River tonight with more showers and a few thunderstorms possible.
(Tonight through Friday night) The tail end of a mid-level trough is pushing through the area today, but with very little moisture (PWAT values at or below 1"), we are not really seeing any signs of it. Current thinking is that while it could allow min temps to drop into the 50s in the Victoria Crossroads and northern Coastal Plains, but most of the area will likely remain in the lower to middle 60s. A low level (below 800mb) westerly flow and drier air will allow temperatures to warm well above normal tomorrow with highs in the lower to mid 90s for most of the region.
(Now through Friday) A cold front currently analyzed in Arkansas and eastern Texas will trudge towards the region tonight. Temperatures behind the cold front won't be cooler thanks to ample sunshine, dry to very dry air, and a westerly wind. Highs Friday rebound into the lower to middle 80s area-wide. There is the potential for elevated fire weather conditions Friday afternoon following the cold front.
126 PM EDT Thu Oct 19 2023 Low pressure tracking east across the Upper Great Lakes today into Friday will push its southward trailing cold front slowly east across the state during the day Friday. Several rounds of showers will precede and accompany this front and a few thunderstorms could even develop across the Lower Susq Valley later Friday afternoon and evening in the mild and moist airmass ahead of the frontal boundary.
(This afternoon through Friday) The cold front is arriving with a SW wind shift to NW for Idabel just this past top of the hour. It is 70 degrees there and could tack on another 10 degrees for the high temp. Other locales are already in the low to mid 70s ahead of the front with perhaps even a touch of compressional heating on tap for the mid afternoon wind NW shift down our I-49 corridor. One area of clouds has cleared our parishes east of I-49 and the cold front is gathering some more mid and high clouds over NE TX at this time.
Light southerly winds continue this afternoon into tonight ahead of a cold front before increasing from the west following the front Friday morning. (Now through Friday) Zonal flow above 850mb will shift northwesterly tonight through Friday as a large upper trough axis from the western Great Lakes region to the northern Gulf shifts eastward and continues to dig southward. Highs will range from 75 to 80 degrees today, warming into the low to mid 80s on Friday due to increasing sunshine, a drier airmass, and westerly winds.
A ridge prevails over the region today, keeping conditions warm and dry through the end of the week.
1231 PM CDT Thu Oct 19 2023 (Today through Friday night) Today and Friday will see ridging pass across the region bringing fair weather and light winds to the panhandles. This ridge will cause abnormally hot temperatures across the panhandles for both days with Friday seeing the zenith of the heat. However the majority of the panhandles should be slightly cooler remaining in the 80s.
(This afternoon through Friday Night) A few light showers have developed over Mid TN, but the activity will blossom more going into the evening as a trough axis approaches the area. Rain chances will shut off by Friday afternoon as the large scale trough axis moves east of the area.
(Tonight through Friday night) Mid and upper level ridging over the desert southwest gradually builds eastward into the region through Friday night. Lows tonight will range from the lower 50s in favored cool spots across the Hill Country to near 60 degrees in urban areas and portions of the coastal plains.
120 PM MDT Thu Oct 19 2023 Upper level high pressure centered across the Northern Rockies and Montana will maintain mild and dry conditions through most of the upcoming weekend with temperatures cooling slightly but remaining above seasonal averages.
1141 AM CDT Thu Oct 19 2023 (Today through Friday afternoon) Hard to get hotter than yesterday's record highs, and we will in fact be cooler today. Compressional warming ahead of the cold front surged temperatures above forecast yesterday, but a slightly cooler airmass behind the weak cold front will bring highs down a few degrees today. A southerly return flow develops today that will only send temperatures warmer tomorrow.
(This evening through Friday night) Looking overhead, we have an upper trough situated over the Great Lakes Region with attached frontal boundary extending from there clear south across parts of northern LA and into TX. Post front, a upper ridge over the desert SW will slide southeast on the backside of the trough. At the surface, weak ridging over the Gulf will usher in dry westerly winds. We are actually going to get hotter, not cooler, afternoon temps.
343 PM CDT Thu Oct 19 2023 An upper level trough over the Great Lakes and an upper level ridge over the Great Basin has placed the Northern Plains in northwesterly flow. Western North Dakota is on the eastern periphery of the upper level ridge resulting in increased heights aloft. A cold front is forecast to move through the state Friday.
138 PM EDT Thu Oct 19 2023 Fair weather continues today as high pressure sits off the mid- Atlantic coast. This weather will continue through the rest of today and tonight before another cold front approaches the region on Friday.
Broad, strong high pressure is over the western United States with the ridge axis aloft centered over southeast Idaho currently.
/Issued 315 AM CDT Thu Oct 19 2023/ /Friday night Onward/ Dry and warm conditions continue this weekend as high pressure remains in control.
151 PM CDT Thu Oct 19 2023 Through tonight: Isolated showers continue to move across the area this afternoon in advance of a cold front that is still situated just to our west from the ArkLaTex into the Mid South.
- Scattered showers will impact the region into this evening and again late Friday/Friday night, with the highest chances Friday night (40-60%) near and north of I-94.
(This afternoon through Friday night) A rather pedestrian short term forecast is in order, as an upper ridge covers the western CONUS, leaving West Texas and Southeast New Mexico under northwest flow aloft in a very dry post-frontal airmass. Friday, the ridge builds southeast into the region, increasing thicknesses/temperatures by around 5F over today's, to a pleasant 12- 14F above normal.
640 PM CDT Thu Oct 19 2023 (Tonight through Friday night) The tail end of a mid-level trough is pushing through the area today, but with very little moisture (PWAT values at or below 1"), we are not really seeing any signs of it. Current thinking is that while it could allow min temps to drop into the 50s in the Victoria Crossroads and northern Coastal Plains, but most of the area will likely remain in the lower to middle 60s. A low level (below 800mb) westerly flow and drier air will allow temperatures to warm well above normal tomorrow with highs in the lower to mid 90s for most of the region.
Early evening satellite imagery is showing widespread cirrus clouds continuing to stream across the Florida Peninsula thanks to a jet streak rounding the base of the upper level trough. High pressure will hold across the area through Friday. An approaching dry cold front will bring winds up to around exercise caution levels late Friday, mainly north of Tarpon Springs.
Light southerly winds become westerly around 10 knots by Friday morning then begin to turn northwesterly in the afternoon as a cold front slowly moves into the area. (Now through Friday) A cold front currently analyzed in Arkansas and eastern Texas will trudge towards the region tonight. Temperatures behind the cold front won't be cooler thanks to ample sunshine, dry to very dry air, and a westerly wind. Highs Friday rebound into the lower to middle 80s area-wide. There is the potential for elevated fire weather conditions Friday afternoon following the cold front.
Dropped lows a couple degrees as we head towards the lower 40s, and perhaps upper 30s in spots. With an upper ridge/northwest flow over the region again tomorrow expect conditions for temperatures to exceed to remain. A dry cold front will move through the region.
637 PM CDT Thu Oct 19 2023 (Tonight) A deep upper trough is expected to traverse the Ohio Valley, Tennessee Valley, and Deep South tonight. Meanwhile, a surface cold front is also slated to progress over the Tennessee Valley. Low temperatures are forecast to merely dip into the lower to mid 50s for most areas due to cloud cover and increased chances of precipitation.
An upper level trough over the Great Lakes and an upper level ridge over the Great Basin has placed the Northern Plains in northwesterly flow. Western North Dakota is on the eastern periphery of the upper level ridge resulting in increased heights aloft. A cold front is forecast to move through the state Friday.
625 PM CDT Thu Oct 19 2023 (Tonight through Friday night) Mid and upper level ridging over the desert southwest gradually builds eastward into the region through Friday night. Lows tonight will range from the lower 50s in favored cool spots across the Hill Country to near 60 degrees in urban areas and portions of the coastal plains.
925 PM CDT Thu Oct 19 2023 A cold front is pushing east through the area and we are seeing scattered showers and a few thunderstorms along and ahead of it. Shower activity will clear the area by the afternoon and as the upper level trough pushes east and we should see sunshine and highs near 70 except over the Plateau where it will remain cooler. (This afternoon through Friday Night) A few light showers have developed over Mid TN, but the activity will blossom more going into the evening as a trough axis approaches the area. Rain chances will shut off by Friday afternoon as the large scale trough axis moves east of the area.
A cold front moving through the region today will switch winds around to northwesterly. The upper level energy associated with the trough is primarily to our northeast, however one additional lobe will slide southeast later today into tonight. Temperatures will be slightly cooler tomorrow, on the order of 1 to 4 degrees.
617 PM CDT Thu Oct 19 2023 (This evening through Friday) Mostly sunny skies and light winds will persist through today with highs in the low-to-mid 80s across the forecast area. Temperatures will continue to increase Friday as an upper ridge currently centered over the Mountain West shifts eastward and surface winds turn more southerly.
734 PM MDT Thu Oct 19 2023 Strong ridge remains in control of the western CONUS. Thus, our eastern cwa will be a little cooler than today, while Billings westward will get back to the upper 70s/near 70F.
Upper level ridge over the forecast area through at least Friday.
A weak front draped across the far northern portions of the area will push into the region as high pressure shifts eastward. Expect increased cloud cover and cooler conditions, but not much in the way of rain for most.
1001 PM EDT Thu Oct 19 2023 Low pressure will track through the Great Lakes and an associated cold front will swing through the region overnight resulting in widespread rain showers through Friday morning.
457 PM MDT Thu Oct 19 2023 Current surface analysis shows low pressure over the western Great Lakes region, with a trough to the west of the area.
