.DISCUSSION...
Issued at 132 PM CDT Fri Apr 11 2025

A quiet stretch of weather hangs around through the weekend as a
high pressure scoots on through. Tonight will get chilly, dropping
near to below freezing, especially along/east of highway 51. A
Freeze Warning is in effect for eastern IL from 2am to 9am
tomorrow morning, elsewhere could see some frosty lawns and
windows in the morning. Highs will warm over the weekend, with
Sunday as the warmest day with highs in the upper 60s to mid 70s.

When the high pushes east, Sunday will be quite windy due to the
increased pressure gradient building in the west that will be
associated with a budding low pressure system over the Plains. Winds
out of the south could gust as high as 35 mph at times.

Monday morning could have some isolated showers as the
aforementioned low pressure travels eastward across the region.
Tuesday will be dry but windy as the associated pressure gradient
exits to the east. The GFS is hinting at potentially bigger system
around the Thursday timeframe.
