Area Forecast Discussion

.DISCUSSION...(This evening through Saturday)
Issued at 231 PM CDT Sat Oct 1 2022

Key Messages:

 - Other than some sprinkles, quiet through Monday night

 - Turning much cooler by the end of next week

Tonight through Monday night...

The upper level ridge currently over the Upper Midwest looks to
remain in place into the early part of next week. This will keep
the weather rather quiet with only some occasional sprinkles about
the only thing going on through Monday night.

Tuesday through Saturday...

The ridge is expected to break down Tuesday allowing the remains
of the closed low currently over the Rockies to weaken and move
across the region Tuesday night and Wednesday. As this is
happening, the northern stream will strengthen with a rather
strong short wave trough expected to rotate around and upper level
low that forms over Hudsons Bay. This short wave trough will help
to deepen the long wave trough into the Upper Midwest for
Wednesday night into Thursday before moving off to the east but
leaving behind a northwest flow pattern to close out the upcoming
work week. The combination of the short wave trough and deepening
long wave trough will drive a rather potent cold front through the
region with high temperatures dropping from the 60s and 70s
Tuesday and Wednesday into the 40s and 50s for Thursday and
Friday. Not a lot of rainfall is expected to occur with the
passage of the front, but there will be some on and off chances
from Tuesday into Thursday.
