.KEY MESSAGES...

.SHORT TERM /THROUGH SATURDAY/...
Issued at 215 PM CST Fri Feb 21 2025

High pressure ridge from MO to KY will continue to push slowly
to the southeast. Skies will be clear tonight and sunny on
Saturday. With a southwest wind through Saturday, temperatures
will not be as cold with lows in the single digits above zero,
and highs finally pushing to near or above freezing. A welcome
change after about a week in the deep freeze!

&&

.LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/...
Issued at 215 PM CST Fri Feb 21 2025

The long term will be highlighted by a milder pattern with more
of a westerly flow of Pacific air rather than arctic origin.
This means snow-eating temperatures well into the 40s with even
some 50s for several days next week!

Precipitation: No significant rain or snow is expected as the
main storm track looks to remain near or north of our forecast
area. We may get clipped by some of this pcpn Monday night and
again on Wednesday into Wednesday night. However, global models
differ on timing and exact track of clipper systems so there is
low confidence at this time.

.AVIATION /06Z TAFS THROUGH 06Z SUNDAY/...
Issued at 1117 PM CST Fri Feb 21 2025

VFR conditions continue throughout the TAF period. Some breezy
southwest winds are likely for the daylight hours Saturday as
atmospheric mixing increases. Gusts to around 20 knots are
possible for most locations. Otherwise, mostly clear skies are
expected, with perhaps some high clouds building in from the
northwest later in day Saturday.
