636 PM CDT Sun Sep 25 2022 (This evening through Monday) Cold front that moved through earlier today will continue to push southward from reinforced northerly winds. Behind the front, drier and cooler air will overspread the area into tomorrow. Dropped the overnight lows a little cooler than NBM owing to the drier air and sufficient radiational cooling. Northerly winds will weaken tomorrow, which will allow for highs to get up into the low to mid 80s with sunny skies.
630 PM CDT Sun Sep 25 2022 (Tonight through Monday night) A weak upper level low can be seen on water vapor imagery this afternoon in northern Mexico. Later this evening, a cold front will begin to approach the area. With highs remaining in the lower to middle 90s, we should see humidity values drop to near 20 percent for points north of I-10.
333 PM MDT Sun Sep 25 2022 Key message: 1) Warmer with localized PM thunderstorms southern mountains Gradual moistening from southerly mid level flow beneath the upper ridge has resulted in some cumulus build-ups across southern portions of the mountains this afternoon. Temperatures will drop into the 30s and upper 20s for some of our cooler valleys with 40s and lower 50s elsewhere. Upper ridge axis remains to our west on Monday with northwest flow continuing over the area. There will still be sufficient moisture under the ridge for some isolated to low end scattered high based thunderstorms across the southern mountains.
519 PM MDT Sun Sep 25 2022 Northwesterly flow aloft continues over the forecast area this afternoon as the region remains between an upper ridge over the western CONUS and an upper trough over the east. Relatively quiet weather will continue through the much of this week due to the broad upper ridge building in from the west.
(The rest of tonight) Cooler and drier air continues to filter into the region behind a cold front which has now pushed down into the ArkLaTex. Winds will gradually back off as high pressure builds into the region. Aside from a few passing high thin clouds, mostly clear skies along with the lower dewpoints and subsiding winds suggest more optimal radiational cooling conditions overnight. The typical cool valley spots, such as KFYV and KBVO, will get considerably cooler than nearby areas.
519 PM EDT Sun Sep 25 2022 Cold front exits east of the mountains this afternoon. A cold front reaches the eastern mountains this afternoon, exiting quickly and ending the showers activity. This will drop lows into the lower 50s lowlands, ranging into the mid 40s highest elevations of our northeast mountains. Below normal temperatures expected for Monday with highs in the lower 70s lowlands, ranging into the lower 50s highest peaks.
436 PM MDT Sun Sep 25 2022 Quiet weather continues through the short term period under the influence of a large ridge.
This trend will continue overnight and Monday, as the upper level ridge orientation shifts. This will bring precipitation chances back into our area, amplifying by midweek, as a series of troughs to our north interact with the moisture. Towards the end of the week, one of the northern stream troughs drops southward through the central Rockies. This is noted by most longer range models, as seasonal westerlies start to take over, moving the upper level ridge to the southeast.
Continued clear, dry, and warming under southwesterly flow aloft between an upper ridge just to our east and an upper trough off the coast.
810 PM MDT Sun Sep 25 2022 Upper level ridging will remain over the area through midweek, bringing generally warm and tranquil weather to the area. Cooler air will work into the area midweek, bringing temperatures back to more seasonable levels for the second half of the week. Again it will be cool overnight with the low dew points.
1120 PM CDT Sun Sep 25 2022 (This evening through Monday) Hot and dry conditions are ongoing across the forecast area this afternoon, with temperatures currently in the low to mid 90s amid sunny skies. Fortunately, a repreive from this unseasonably warm weather is on the horizon, with a large eastern CONUS trof expected to push a cold front into the region early tomorrow morning.
The mid level flow pattern is predominantly northwest, with a broad trough to our east, generally over the Great Lakes and Hudson Bay portions of Canada. This flow pattern will remain mostly persistent through the middle part of the week, so in conjunction with the surface ridging over the area, there does not appear to be much in the way of low level or mid level mechanics for lift or enough moisture in the area to use for precipitation. Despite the chance for warmer than average days ahead temperatures should still be autumn-like and comfortable with most areas remaining in the 70s or lower 80s all week and weekend.
959 PM MDT Sun Sep 25 2022 Quiet weather continues through the short term period under the influence of a large ridge.
239 AM CDT Mon Sep 26 2022 Dry northwest flow aloft will continue the next couple of days downstream from an expanding upper level ridge across the Great Basin. By the middle and latter portions of the work week the ridge will shift eastward into the Central and Southern Plains as an upper trough digs into the northern Rockies. At the surface, high pressure is centered across central Nebraska early this morning. The high will shift southeastward into eastern KS and MO this afternoon with winds light today in its wake. Winds tonight will remain light and it will be another cool night with lows in the lower to mid 40s.
(Today and tonight) More seasonable temperatures are expected today following a cold front yesterday. An upper level ridge that had built over the western CONUS this past weekend will begin to shift overhead today.
Another beautiful fall evening across the high country with clear skies and dry conditions. Dew points are already in the low to mid 30s through much fo the higher elevations and in the lower 40s across the valley areas. Overnight temperatures may even drop to at or below freezing a few spots. This trend will continue overnight and Monday, as the upper level ridge orientation shifts. This will bring precipitation chances back into our area, amplifying by midweek, as a series of troughs to our north interact with the moisture. Towards the end of the week, one of the northern stream troughs drops southward through the central Rockies. This is noted by most longer range models, as seasonal westerlies start to take over, moving the upper level ridge to the southeast.
1219 AM CDT Mon Sep 26 2022 (Tonight through Monday night) A weak upper level low can be seen on water vapor imagery this afternoon in northern Mexico. Later this evening, a cold front will begin to approach the area. With highs remaining in the lower to middle 90s, we should see humidity values drop to near 20 percent for points north of I-10.
1057 PM CDT Sun Sep 25 2022 (Tonight) Isolated to scattered thunderstorms that moved through the area along a prefrontal trough axis has dissipated. However, the cold front remains in place behind this feature and stretches from near Winchester, TN southwestward to just north of Columbus, MS. Given mainly light winds, good radiational cooling aided by some weaker cold air advection should allow temperatures to drop into the lower to mid 50s in most areas.
330 AM CDT Mon Sep 26 2022 An upper level low over the Great Lakes and a ridge over the Great Basin has locked the Northern Plains into northwesterly flow. Tonight a back door cold front will move through the region shifting winds out of the east.

1226 AM CDT Mon Sep 26 2022 Scattered storms over our eastern counties produced some near- severe hail and gusty winds late this afternoon ahead of a cold front.
Upper level ridging will remain over the area through midweek, bringing generally warm and tranquil weather to the area. Cooler air will work into the area midweek, bringing temperatures back to more seasonable levels for the second half of the week. Again it will be cool overnight with the low dew points.
1211 AM CDT Mon Sep 26 2022 (This afternoon through Monday night) Isolated showers and thunderstorms have been ongoing across the northern half of the Permian Basin since late this morning ahead of a cold front that has now moved into the region. In the wake of the front, high temperatures today will be a couple degrees cooler than yesterday, with lows tonight expected to dip into the lower to middle 60s for most, with middle to upper 50s possible for the higher terrain and portions of Southeast New Mexico and the northwestern Permian Basin. Continued cold advection Monday will also result in cooler, near normal temperatures, with highs in the lower and middle 80s for most, 70s in the mountains, and 90s through portions of the Rio Grande Valley.
(Today) High pressure will reign supreme across eastern Oklahoma and western Arkansas today. (Tonight through Sunday) Dry weather is expected this week and into the weekend as high pressure prevails at the surface and aloft.
