.DISCUSSION...
Issued at 226 AM CDT Wed Sep 17 2025
Persistent upper ridging remains in control of the region as of
this morning. A downstream upper low is situated across
Virginia and the Carolinas with upstream troughing across the
Rockies and northern plains. The weak inverted trough that
managed to spark a few showers yesterday will remain across the
area today. Drier northeasterly flow will help to keep
conditions dry today as PW`s drop to below an inch. High
temperatures will likely be similar to yesterday with highs in
the low to mid 90s. The dry weather and continued hot
temperatures remain through Friday. Thursday looks a bit warmer
as the ridge axis moves directly overhead in response to height
falls across the northern and central plains.
We see a pattern change taking place late this week, from
Friday and continuing through the weekend into early next week.
Upper troughing will move east into the Midwest Friday, pushing
through the region over the weekend. Additional troughing looks
to develop within cyclonic flow into early next week. This
pattern would support chances of showers and storms, although
coverage and amounts are uncertain. Ensembles continue to show
overall limited amounts through the weekend, and certainly not
enough to make any notable dents into the ongoing drought.
Overall, temperatures will cool a few degrees this weekend into
early next week with highs in the mid to upper 80s to near 90.
