.SHORT TERM... (Tonight through Thursday Night) Issued at 1042 PM CDT Tue Sep 16 2025
If you got rain today, it`s pretty steamy out there. The 00Z balloon launch revealed a stark temperature inversion just off the surface, so we could certainly see some fog tonight. Best chances for areas of patchy dense fog development will be over areas that received rain today which includes a large chunk of the northeast quadrant of our CWA. Do still see some clouds over the area that are pushing off of the low to our east, but assuming those clear out, watch out for fog overnight.
Our winds will shift out of the northeast by late Wednesday morning, ushering in drier air, and thus limiting rain/storm chances tomorrow. More of the same can be expected Thursday with temperatures ever so slightly higher as the ridge aloft continues its push east.

.LONG TERM... (Friday through next Wednesday) Issued at 1042 PM CDT Tue Sep 16 2025
Friday will be our hottest day this week as the ridge moves directly overhead with widespread afternoon temperatures in the mid 90s east of the Plateau (mid to upper 80s there). It still looks like Friday, although hot, will be dry most of the day, so hopefully evening ballgames can commence without interruptions from the weather. It is worth noting that some models are showing rain/shower chances picking up Friday night as troughing from the midwest builds in, but will have a better idea once we are in viewing range of higher-res models. With the trough moving in, lower heights are currently off to our north, meaning Saturday will still likely be hot and mostly dry, but with an increase in cloud cover and perhaps some showers. Euro ensembles are currently giving a 50% chance of at least a hundredth of an inch of rain, mainly across the western half of the CWA. The trough will dip lower into the area Sunday, bringing a low 20% of rain and storms with temperatures just a few degrees cooler in the upper 80s. Moving into next week, troughing will remain the dominant synoptic feature that influences our weather. This will help to slightly regulate temperatures back into the mid to upper 80s and also provide more opportunities for rain. Low rain chances between 15% to 20% are in the forecast each day beyond Saturday.
