.DISCUSSION...
Issued at 247 AM CDT Fri Oct 10 2025
A surface high pressure system will remain in control of the
weather across the Quad State through the upcoming weekend.
Aloft, 4-state region will be on the east side of an upper-level
ridge axis allowing for cooler northwest flow into the area. At
the same time, a fairly deep upper-level low is progged to dive
southeastward through the Great Lakes before meandering to the
northeast CONUS. The main impact from that system on our weather
will be an amplification of the aforementioned ridge to the
west. There is a weak cold front/surface trough that will drift
through the area tonight, which may have just enough moisture to
touch off some sprinkles and to increase cloud cover.
Otherwise, dry weather is anticipated through the weekend.
Temperatures are expected to be below normal through Friday
before warming above normal over the weekend. Highs will mainly
be in the low 70s with lows in the 40s to low 50s.
An upper-level ridge axis will build directly overhead for early
next week, leading to another substantial warmup across the area.
Most locations will warm into the low 80s, which is about 10 degrees
above normal for this time of year. As warm air advection and
moisture increases across the area, expect an increase in cloud
cover early next week as well. Right now it doesn`t look like any
great chances for precipitation as most of the systems remain well
north and west of the Quad State area.

.AVIATION /12Z TAFS THROUGH 12Z SATURDAY/...
Issued at 632 AM CDT Fri Oct 10 2025
VFR conditions are expected to be the main flight rules for this
TAF issuance as high pressure lingers overhead. A cold front
will approach the area this evening, allowing for an increase in
cloud cover and perhaps a few sprinkles. Additional ground fog
may form at CGI/MVN if clouds clear quick enough overnight.
Winds will be light and variable.
