.DISCUSSION...
Issued at 245 PM CDT Wed Oct 8 2025
Calm winds and clear skies allowed for excellent radiational cooling
this morning. Relatively cold temperatures aided in the development
of fog in low-lying areas as a result. With surface high pressure
now east of the area, southerly winds and sunny skies quickly burned
off this patchy fog. Temperatures have climbed to around 70 F across
the region this afternoon under plentiful sun. Increasing clouds are
beginning to enter the area as a weak weather system lifts northeast
towards us. While a few weak radar echoes may develop, observed and
forecast soundings show a dry sub-cloud layer that should make it
difficult for anything to reach the ground. The quiet weather
continues through the end of the work week as temperatures gradually
warm. Mid 70s on Thursday give way to temperatures near 80 by Friday
with continued dry weather.
A pattern change begins this weekend. First, a digging shortwave
over the Great Lakes brings a cold front and low precipitation
chances on Saturday. The cool down is short-lived as the pattern
amplifies in response to a deepening trough over the western CONUS.
This pattern amplification pushes temperatures back into the 80s
with additional low-end precipitation chances possible. By next
week, the western CONUS trough remains relatively stationary with
weaker shortwaves quickly lifting northeast into the northern Great
Plains. This is anticipated to bring another cold front through the
area to start the new work week, cooling temperatures. Precipitation
chances continue also, but remain relatively low probability at this
time.
