946 AM EDT Thu Sep 5 2024 Dry weather continues as high pressure slowly drifts across the region through the end of the week. Behind the boundary drier weather returns along with cooler air. Dewpoint temps should start to come down amid the continued dry airmass, but limited winds in the low levels will keep these from getting too dry. Otherwise high pressure in control today and sunny skies and pleasant temps will be the rule. Tonight high pressure remains in control but center drifts east slightly from its position this morning. As flow on the backside of high pressure becomes more onshore overnight. and temps will be slightly cooler than today.
643 AM EDT Thu Sep 5 2024 High pressure from the north will provide slightly below normal temperatures for the remainder of the week under northerly flow.
Afternoon highs will top out in the lower to middle 90s with heat index values reaching into the 105-110 degree range.
422 AM PDT Thu Sep 5 2024 The heat from high pressure aloft is expected to peak for today and Friday with high temperatures as much as 15 to 20 degrees above average for portions of the valleys and inland coastal areas.
612 AM CDT Thu Sep 5 2024 *Lingering isolated showers and thunderstorms this morning *Areas of haze this morning into the afternoon *Cooler the next couple days *Temperatures warm back into the 90s by the latter half of the weekend As a weak trof advances through the forecast area, scattered light showers and an isolated embedded thunderstorm may be possible this morning, generally east of HWY 83. QPF values will remain low, although there is some increased moisture ahead of the trof, there is a layer of drier air near the sfc, thus expect rainfall amounts to be negligible. As for temperatures, a cooler airmass behind the front will keep temperatures in the upper 70s to low 80s today and Friday. An upper level ridge builds in across the western CONUS and moves east into the High Plains by this weekend.
625 AM CDT Thu Sep 5 2024 A few light isolated showers and thunderstorms will remain possible through Friday ahead of a cold frontal movement. A beautiful weekend will be on display behind Friday's cold front, with highs in the mid 70s to lower 80s and rain free conditions. High pressure will bring seasonable temperatures and dry weather next work-week.
518 AM MDT Thu Sep 5 2024 - Building high pressure brings a mild and dry day today.
This will allow for slightly better heating with highs rising to the low 90s in NW AL under partly to mostly clear skies.
514 AM EDT Thu Sep 5 2024 A ridge of high pressure over the Commonwealth will maintain cloud-free skies through this morning.
UPDATE The cold front is continuing to push south and most visibility impacts from wildfire smoke are south of our area and air quality sensors are already green in the north and trending towards yellow. Light showers are still lingering over the northwest angle (closer to the mid level trough) and in our far south near the cold front. Otherwise, the main change is a period of low stratus filling in where there was clearing behind the cold front (a bit more scattered in northeast ND currently). A mid/upper trough is continue to move over the region, while it's associated cold front is moving through our CWA. The trough deepens to the northeast in Canada and north-northwest will be in place tonight into the weekend.
607 AM CDT Thu Sep 5 2024 - Highs around 90 are forecast today before a strong cold front moves through Friday, accompanied by very limited rain chances. Skies should be mostly clear as we sit in fairly dry air off the surface with weak subsidence aloft with temperatures working into the lower 90s. A strong cold front then approaches with air sourced from west of Hudson Bay, Canada.
427 PM EDT Thu Sep 5 2024 - After another warm day on Friday, a cold front passing on Friday night will bring a noticeable cool-down for the weekend. - Showers or thunderstorms are possible late Friday into Friday night in association with a cold front. An upper level trough is dropping southeast over the north central CONUS late today, with an associated surface cold front extending from MI southwest through the Mid Mississippi Valley.
Ample sunshine, temperatures in the lower 90s, and dew points hovering near 80 yield a calculated heat index between 105 and 112 along most of the island chain. Meanwhile, sprawling high pressure extending across the North Atlantic, with its axis transecting central Florida, will dominate the sensible weather closer to home in the Keys.
1135 AM EDT Thu Sep 5 2024 High pressure will slowly exit to the east today and tonight. Low pressure will approach from the south through the end of the week.
Tonight, a Gulf low pressure will continue to push east. While a majority of associated rain and moisture will stay well south of our CWA, low rain chances (10-20%) have been introduced early tomorrow morning as HREF model guidance indicate potential for very light showers along the northern periphery of the low pressure.
- Daily chances of precipitation over and near the higher terrain. Additional showers were still back in the mountains as trough axis per radar loops was clearly located from near Salida SSW into the San Juans. A good part of the San Luis Valley was still seeing sun, and with trough still to their west indicates this area is still quite unstable. As trough axis continues to push southeast, expect best chance of rain and thunder will be over the SLV and the southern mtns the remainder of this afternoon.
Updated at 206 PM CDT Thu Sep 5 2024 - Showers & some storms possible into early Friday - Low chance again Friday afternoon in SE - Near/below average temperatures continue into the weekend (This evening through Friday) Cold front is beginning to move into far NW Oklahoma.
1209 PM CDT Thu Sep 5 2024 A few light isolated showers and thunderstorms will remain possible through Friday ahead of a cold frontal movement. A beautiful weekend will be on display behind Friday's cold front, with highs in the mid 70s to lower 80s and rain free conditions. High pressure will bring seasonable temperatures and dry weather next work-week.
237 PM EDT Thu Sep 5 2024 High pressure maintains a cool northeast breeze through today, keeping temperatures below normal.
245 PM CDT Thu Sep 5 2024 - Scattered showers and storms (15-30% chance) this afternoon and evening as a cold front continues to move through the area. - Cooler temperatures build in behind the front with below normal temperatures Friday through the weekend.
136 PM CDT Thu Sep 5 2024 - A cold front will bring markedly cooler temperatures this weekend and refreshingly lower humidity. A cold front makes its approach and passage during the next 24 hours.
Today, north-northwesterly flow aloft can be found over the northern Plains as a deepening upper level trough over the Great Lakes regions is pushed eastward by an approaching upper level ridge from the western CONUS. While dry conditions are anticipated to continue, some showers wrapping around a low pressure center moving into northern Minnesota may skirt the northeastern North Dakota overnight, though these showers are expected to remain to our east at this time. Low temperatures tonight are forecast are generally in the lower 40s, with a few cooler spots potentially dropping into the lower 30s. The eastward progression and amplification of the western CONUS ridge through the end of the week will promote a warming trend across western and central North Dakota.
1231 PM CDT Thu Sep 5 2024 - Cold front expected to bring showers and possibly storms to the area starting Thursday evening.
Shower and thunderstorm chances will increase through the evening to the northwest of Tulsa as the much anticipated cold front approaches. Overnight lows should be just a bit warmer than those seen last night, with values near to just above normal in most spots. (Tomorrow through Thursday) The aforementioned cold front will push through the area Friday, bringing below normal temperatures during the day and down right chilly temperatures for some during the overnights.
1055 AM MDT Thu Sep 5 2024 - Building high pressure brings a mild and dry day today.
otherwise cumulus was forming over the higher terrain this afternoon. Arthur Ridging will build in for the weekend, allowing for warm and dry conditions.
141 PM EDT Thu Sep 5 2024 High pressure is sliding to the east.
110 PM EDT Thu Sep 5 2024 High pressure from the north will provide slightly below normal temperatures for the remainder of the week under northerly flow.
After midnight, a weak cold front will sag southward into the area, accompanied by a northerly wind shift, and a period of gusty winds toward daybreak Friday that could see winds gusting to around 20-25 mph. The best chance for precipitation (20- 30%) will exist along and west of the Pecos River, where upslope flow against the higher terrain will facilitate additional development. Precipitation will once again taper off after sunset Friday evening, paving the way for a quiescent night with lows again in the 50s and 60s for most, and even some upper 40s possible in the higher terrain of the Davis Mountains.
1228 PM CDT Thu Sep 5 2024 *Lingering isolated showers and thunderstorms this morning *Areas of haze this morning into the afternoon *Cooler the next couple days *Temperatures warm back into the 90s by the latter half of the weekend As a weak trof advances through the forecast area, scattered light showers and an isolated embedded thunderstorm may be possible this morning, generally east of HWY 83. QPF values will remain low, although there is some increased moisture ahead of the trof, there is a layer of drier air near the sfc, thus expect rainfall amounts to be negligible. As for temperatures, a cooler airmass behind the front will keep temperatures in the upper 70s to low 80s today and Friday. An upper level ridge builds in across the western CONUS and moves east into the High Plains by this weekend.
Discussion: The forecast area remains caught between two weather systems; an upper trough approaching the Great Lakes region and a closed upper low nearing the central Gulf Shore. Enhanced moisture associated with the closed low remains well to our south and a weak cold front drapes from the upper Midwest into the central CONUS.
Latest upper air analysis shows the ridge centered over Nevada and California. East of the ridge the short wave trough was moving southeast onto the Plains. Smoke from wildfires was accompanying the trough. Further southeast the cold front continued southeast across the Plains. Tonight the sky will clear as subsidence behind the departing upper level short wave trough moves in. Friday will be dry as the ridge continues to slowly build east onto the Plains. Highs will be a few degrees warmer than today due to the lack of cloud cover. Friday night a backdoor cold front will move into the forecast area from the northeast behind a weak upper level short wave trough rounding the ridge.
204 PM CDT Thu Sep 5 2024 - A cold front will bing a 20-30% chance of showers to central IL late tonight and early Friday morning. A cold front was analyzed over eastern IA at 18z and regional radars showed a broken band of post frontal showers behind it. The main story will be the arrival of a much cooler airmass on north/northwest winds gusting 15-25 mph. Much of central IL will only see low/mid 70s highs Friday, with areas south of I-70 still getting into the lower 80s.
A weak trough/axis of higher dewpoints and ML CAPE of 500j/kg was located just southeast of I-44 where a cumulus field has developed. A cold front with much cooler temps behind it has now pushed into far northwest Missouri. The rest of the area will likely remain warm and dry with areas west of Springfield reaching the lower 90s. The cold front will continue moving southeast and short term models generally bring it into the area around midnight.
1138 AM MDT Thu Sep 5 2024 - Much cooler today with highs in the 60s to 70s! - Widespread showers and thunderstorms along the Continental Divide and San Luis Valley through this evening.
Satellite imagery this afternoon is showing a high amplitude ridge of high pressure over the western U. Expect daytime highs in the upper 80s to lower 90s across the valleys of western Montana and Lemhi County, while the lower Salmon and Clearwater River valleys achieve triple digits.
Otherwise the forecast of slightly warmer temps is on track for today. Temperatures today will be a bit warmer than recent days, with afternoon highs mostly in the upper 80s to lower 90s.
(This afternoon through Friday Night) Our quiet weather will continue today as a short wave ridge moves overhead. Highs will be a bit warmer compared to yesterday pushing into the lower 90s for some.
1049 AM MDT Thu Sep 5 2024 - Cooler today with decreasing cloud cover through the day.
- Much cooler temperatures expected into the weekend.
1000 AM PDT Thu Sep 5 2024 High pressure aloft will bring very hot weather today and Friday with high temperatures as much as 15 to 20 degrees above average in portions of the valleys and inland coastal areas.
215 PM MDT Thu Sep 5 2024 - Warmer and mostly dry conditions through the weekend. Water Vapor and upper air models show upper ridge over the western CONUS, with upper trough digging into the Great Lakes region, and northwest flow over the forecast area. Aside from that, expect dry conditions through the weekend as the upper ridge begins to slide over the Rockies into the plains.
1239 PM CDT Thu Sep 5 2024 (Today through Friday night) Latest observations this morning show areas of dense fog developing south of the CWA as the low levels become saturated with cooling. Sfc obs also show the anticipated weak cold front approaching from our north, currently stretching over the eastern plains of CO & NM into western KS. This lifting mechanism is still on track to push through the Panhandles this morning, bringing slightly cooler temperatures and about 20-30% coverage of scattered convection in its wake through the day. Temperatures today and tomorrow are currently forecast to stay in the 80s, although some models suggest cloud cover and a somewhat stronger push of cool air behind the front may keep highs a few degrees cooler than the NBM indicates.
Main cold front seen on sfc observations and cloud patterns on Vis satellite, currently pushing along and west of the MS RVR. Overnight, large upper low will look to continue to dig out of the Hudson Bay region and toward the northwestern GRT LKS through Friday morning. As upper low adjusts acrs the western GRT LKS, steep cyclonic flow and cooler temps aloft will set up an isolated to wdly sctrd instability shower regime down acrs the upper MS RVR Valley. Cool core high pressure settles down acrs the upper Midwest, but enough incoming presssure gradient to maintain north to northeast winds of 5-10 MPH Friday night. H85 Mb cold rule supports lows in the low 40s with even some upper 30s possible.
101 PM CDT Thu Sep 5 2024 Updated aviation portion for 18Z TAF issuance - Showers and thunderstorms are possible today into this evening along a cold front moving across the area.
319 PM CDT Thu Sep 5 2024 - Cooler temperatures expected Friday through the weekend, with a few lingering showers as low pressure exits on Friday.
Some isolated showers and thunderstorms are still expected, but the higher QPF values are focused across interior portions of the state. For the weekend, a trough will dig across the eastern U. causing the ridge axis to shift south of our region.
202 PM EDT Thu Sep 5 2024 Fair dry weather is expected through Friday as High pressure lingers over the region.

1119 AM EDT Thu Sep 5 2024 High pressure over the region will provide dry and unseasonably cool weather through Friday.
400 PM EDT Thu Sep 5 2024 High pressure will slowly exit to the east tonight.
119 PM EDT Thu Sep 5 2024 Very warm temperatures will continue today as high pressure influences our weather. A change in the weather pattern is then forecast with the transition day expected on Friday as a cold front advances southeast across the Great Lakes and Ohio Valley. Dry and much cooler weather is anticipated for the upcoming weekend as high pressure of Canadian origin settles into the Ohio Valley. A large digging mid level trough is expected to move into the Great Lakes and Ohio Valley by Friday night. An associated cold front in advance of this trough will combine with some moisture, diurnal instability, and increasing frontal convergence to bring increasing chances for showers and embedded thunderstorms. For tonight, clouds will increase across the northwest as the cold front encroaches from the northwest.
A cold front will dive south across the region on Friday with high pressure building in its wake. Scattered convection expected during the day on Friday as the front moves south across the ArkLaTex beneath an upper-level trough lingering areawide. High pressure building from the north will drive the tropical disturbance south into the central gulf by Friday night allowing for the start of a period of drier conditions across ArkLaTex. Temperatures on Friday to range from the lower 90s across the I-30 corridor to the upper 70s across portions of north Louisiana where scattered convection and cloud cover are expected ahead of the front. On Friday night, overnight lows areawide to average in the 60s across much of the area except for slightly cooler low temperatures in the 50s across the higher elevations of southeast Oklahoma.
1130 AM EDT Thu Sep 5 2024 High pressure will bring dry conditions through Friday.
Precipitation chances remain intact, mainly across portions of the far southwestern TX Panhandle as the weak cold front begins to pass through. As for Friday a pleasant weather day as the upper high over southwestern CONUS begins to extend eastward into portions of West Texas. Winds are expected to remain out of the north behind the front which will help keep temperatures at bay with upper highs in the low to mid 80s, with a few localized areas rapping out in the low 90s across the Rolling Plains.
An upper level ridge will continue to bring warm temperatures and dry conditions through Friday.
1234 PM CDT Thu Sep 5 2024 - Cold front brings scattered showers and generally weak storms this afternoon and evening. Looking at the large scale pattern this morning, a positively tilted trough is deepening across the north-central CONUS. This is pushing a cold front southeastward across the Plains, which will move across the forecast area this afternoon. Ahead of the front, deep mixing will be in place, allowing temperatures to rise into the low 90s. Given the forecast frontal position by peak heating, east-central Kansas has the highest chance of seeing convection develop. Behind the front, cooler and much drier air will filter in for the weekend, as the trough becomes a deep upper low over the Great Lakes.
A cold front will cross the region tomorrow afternoon and will result in a beautiful weekend.
Surface analysis depicts sprawling high pressure centered north of the Azores, extending southwestward to the eastern Gulf of Mexico. The forecast for the balance of today calls for mostly sunny skies, slight rain and thunder chances, and highs in the lower 90s.
The lower level clouds will most likely move in with any measurable precip that pushes from south to north later tonight and early tomorrow.
The main impact today will be temperatures which will climb to well above normal this afternoon ad an area of high pressure remains overhead. Well, the north-northeast flow around the high center over Nevada will transport that smoke/haze into the southern Great Basin and Mojave Desert today, with some of it lingering into Friday. North winds will hang around within the lower Colorado River Valley through Friday morning before weakening. Temperatures set to peak today with high overhead, then give back 1 to 3 degrees Friday as the high center shifts east toward the Four Corners.
- High pressure builds in for the start of the weekend though an odd shower or storm could fire over the San Juans Friday.
