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 1100 PM CDT Sat Sep 27 2025
CIGS: mostly SKC conditions through Sunday into Monday.
WX/vsby: river valley fog remains the primary concern for KLSE.
RAP/HRRR/NAM12 soundings trend too much wind in the near sfc layer
for any fog/stratus to move off the river and impact KLSE - and will
continue to follow this for the forecast.
WINDS: light/vrb overnight becoming more south/southeast Sunday but
holding under 10 kts.
