.SHORT TERM... (Today and tonight) Issued at 1235 AM CDT Mon Sep 22 2025
The shortwave that brought some weather to our southeastern counties last evening was seen translating off to the east as an upper level ridge begins to track into the region, via water vapor imagery. This ridge will begin to flatten this afternoon in response to a shortwave trough digging into portions of the southern Intermountain West. As a result, northwest flow aloft will become more zonal this afternoon which should lead to mostly dry conditions through the afternoon and evening. At the surface, southeasterly winds will veer out of the southwest by daybreak as a lee side low develops across southeastern CO. Until then, very moist low levels with dewpoints in the lower 70s appear favorable for some patchy fog this morning in the southeast TX Panhandle and adjacent areas. The warm downslope component to the winds from the surface to H7 will drive WAA into the FA, which combined with the slight increase in thickness values will lead to slightly warmer temperatures compared to yesterday despite height values remaining neutral. Although only a subtle warm up is expected, temperatures will still be unseasonably hot this afternoon with record breaking heat possible at KCDS and KLBB with highs forecast in the 90s to lower triple digits. As it stands, KLBB looks to have the best chance of breaking the record (98 degrees in 1977) with a forecasted high of 99 degrees. KCDS could see the record broken (101 degrees in 1977) although the current forecasted high is a few degrees shy of this of 97 degrees.
By the late evening, subtle perturbations tracking through the southern periphery of the shortwave trough will begin to track into the region. Some hi-resolution models hint at a few isolated to scattered showers and thunderstorms developing within these vort maxes and into areas across the Caprock overnight. Although lift will be present from these perturbations, lack of moisture will likely limit any beneficial showers and thunderstorms. As forecast soundings across the area show dry air throughout much of the mid- levels down to the surface. Thus leading to a low confidence forecast in regards to precipitation chances overnight. If a thunderstorm or two develops, inverted-v forecast soundings suggest there could be a few localized stronger wind gusts.

.LONG TERM... (Tuesday through Sunday) Issued at 1235 AM CDT Mon Sep 22 2025
The unseasonably hot temperatures will not continue into the long term forecast thankfully as the upper level shortwave trough over the Intermountain West digs into portions of the Four Corners region before translating into the Central Plains by mid-week. As a result, the surface low out ahead of the system will shift east, allowing for the associated FROPA to surge southward into the Texas Panhandle region Tuesday afternoon. Compared to recent model runs, we are seeing much better agreement between models with the consensus looking like the front reaching our northwestern counties by daybreak. One thing to note, this front looks to be decently strong which could allow for the front to be more progressive which could lead to much cooler temperatures across much of the FA. Due to the uncertainty in this solution will go ahead and maintain NBM "warmer" temperatures depicting a large gradient oriented from the southwest to northeast. With cooler highs to the west of the gradient and warmer highs to the east of the gradient as post frontal northerly winds advect cold air in from the north. Additionally, as this front moves in from the north it will bring the primary source of lift for shower and thunderstorm development along the boundary Tuesday afternoon. As a result, coverage in storms will also be dependent on the evolution and timing of this FROPA. Similar to the short term, one thing that continues to throw a wrench in widespread and beneficial PoPs looks to be the lack of moisture present across the region with dry west to southwesterly winds at the H7 to H5 levels. Much of the moisture that will be at play will likely be associated with the FROPA moving in with post frontal northerly winds brining in CAA and potential moisture from the north.
The upper level shortwave extending from the Central Plains to the Upper Midwest, will become positively oriented through mid-week as it shifts east. In response, the H5 jet streak will set up over the northern Texas Panhandle with the FA within the right entrance region of the jet. Depending on the amount of moisture return present across the region, supportive jet dynamics will allow for additional rounds of showers and thunderstorms Wednesday. Although the precipitation forecast is a bit wishy washy, the good news is that temperatures will be cooler compared to the last several days in the 70s and 80s through Thursday. By Friday, an upper level ridge over the Desert Southwest will shifts east as an upper level shortwave trough off the California coast moves inland. Thus leasing to increased thickness and height values and the return of warm and dry conditions Friday. This trough is expected to develop into a cutoff low through the weekend with deterministic guidance, as expected, a bit all over the place with the placement of this system. Although ensemble guidance does hint at this system being our next chance of seeing beneficial rainfall through the weekend.

.AVIATION... (06Z TAFS) Issued at 1235 AM CDT Mon Sep 22 2025
Threat for fog and low CIGs is mounting in the CDS area in the coming hours. Satellite shows a growing area of low stratus about 15N CDS which should expand south by 09-10Z and linger until 15Z or so with widespread LIFR-IFR likely. PVW and to a lesser extent LBB may get clipped by some of these low clouds and fog by daybreak but for now VFR should hold firm.
