Dry and Mild Weather Through Midweek:
A shortwave trough continues to move through southern Canada this
morning. With the better moisture staying to the north of the CWA,
the only impact from this shortwave for our area will be a wind
shift from the southeast to the northwest. These winds will shift
back to the southeast Sunday morning as ridging builds back in.
Ensemble and deterministic guidance continues to show this ridge
over our region through much of next week. The ridge axis will move
over the Upper Midwest on Monday and Tuesday then the ridge is
expected to flatten out a bit heading into next weekend allowing for
rain chances to come back into the forecast. Temperatures over the
next week will be around 10 degrees above normal with Monday and
Tuesday closer to 10 to 15 degrees above normal. This means highs in
the mid 70s to near 80 degrees are expected most days, with the
exception of Monday and Tuesday where highs will be in the upper 70s
to low 80s.

Issued at 500 AM CDT Sat Sep 27 2025
CIGS: SKC/SCT through the period with some high level (15-20kft)
clouds attached to a passing trough/cool front today. Some threat
for low stratus at KLSE Sunday morning.
WX/vsby: only concern is for the potential fog/low stratus at KLSE
the next few mornings. T/Td spreads, sfc winds, and the depth of the
light wind layer, will be the main factors to keep an eye on. As of
now, RAP/NAM suggest the vert wind speeds will be too brisk to
support fog late tonight/Sun morning - but could lighten up enough
for 300 ft stratus to spread across KLSE. Something to watch.
WINDS: winds will swing west/northwest with the passage of the cool
front this morning. Some increase to around 10+ kts post the front,
but those settle down this evening as a sfc high moves back in.
