Dry and Mild Weather Through Midweek, Low Rain Chances Return Next
Weekend:
Ridging builds in today as the shortwave trough that came through
yesterday has exited the region. Mild and dry weather are expected
through the week. Winds will shift to the southeast this morning and
stay out of the southeast through most of this week. Ensemble and
deterministic guidance has this ridge overhead through much of the
week. As a result, temperatures are forecasted to be 10 to 15
degrees above normal with some locations approaching 20 degrees
above normal. This translates into high temperatures mostly in the
upper 70s to mid 80s. By the end of the week, ensemble guidance
shifts the ridge axis to the east and most (about 85%) of the
ensemble members support the ridge flattening out a bit and a
longwave trough approaching from the west, however the strength and
timing of this trough are quite uncertain at this time. The ridge
becoming less amplified will allow for shortwaves to pass through
and increase rain chances as we head into the weekend.

Issued at 1225 PM CDT Sun Sep 28 2025
VFR conditions are expected for much of the TAF period outside
of a 20-30 percent chance for shallow IFR/LIFR fog east of the
Mississippi River and IFR stratus within the Mississippi River
Valley between 09-14Z--the lower confidence driven by stronger
winds just off the surface. Winds remain light from the
southeast to south around 5 kts.
