.DISCUSSION... Issued at 305 PM CDT Tue Sep 23 2025
A cloudy and dreary day has been observed across much of the forecast area today as a weak frontal boundary persists just south of the local forecast area. Temperatures have ranged from the upper 60s to lower 70s, about 5-7 degrees below seasonal norms. So far, most locations have received fairly modest precipitation amounts during the daytime hours, ranging from a trace to around a quarter of an inch of precipitation, with more clouds than periods of rain.
For the remainder of the afternoon and evening hours, expect a possible uptick in precipitation as the upper level disturbance across the central Rockies transitions into Kansas. In fact, it looks like there is already an uptick in activity late this afternoon across western portions of the area, as supported in mesoscale model data. Overall, while there is not much instability to work with, there could still be enough forcing for a weak thunderstorm or two this evening, and for this reason did not pull the mention of thunder despite being mainly thunder free so far this afternoon.
As the upper level wave then pushes east on Wednesday, skies should clear across the local area - which combine with northeasterly flow wrapping around the departing disturbance, could result in a few afternoon sprinkles mainly for areas east of 281. This will be a low impact event, and most will just enjoy return of partly/mostly sunny skies and seasonal temperatures Wednesday afternoon.
Thereafter...a weak upper level ridge will build back across the area for the majority of the extended period as models keep a cutoff area of low pressure across southern California. This should result in seasonably warm temperatures (mainly low 80s) along with dry weather through the upcoming weekend. The aforementioned low will eventually make its way into the southwest and southern plains early next week, but little change to the weather pattern is anticipated locally as ensembles have a fairly high confidence dry signal through at least next Tuesday.

.AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/... Issued at 1229 PM CDT Tue Sep 23 2025
For KGRI/KEAR Airports:
IFR or MVFR CIGS will continue for the next couple of hours as widespread -SHRAs continue to impact the region. Expect gradual improvement in CIGs/VSBYs through the late afternoon hours as the responsible disturbance shifts south...with VFR conditions eventually returning during the late night through overnight hours as skies begin to clear from north to south. Given the way this system is wrapping up, CIGS/VSBYS will likely remain worse at KEAR than KGRI for a couple of hours...before eventually SCT CIGS return aft 24/12Z. Winds will be predominantly out of the north through the period...diminishing to 5-6KTS overnight... before again increasing to around 10 KTS during the daytime hours Wednesday.
