.DISCUSSION...
Issued at 327 PM CDT Tue Oct 7 2025
A quiet remainder to the work week is expected across the region.
Surface high pressure is currently settling into the area as our
most recent weather system continues to track off to the northeast.
That being said, a weak disturbance is resulting in scattered
cumulus and weak radar echoes early this afternoon. This activity is
not expected to result in any precipitation. A dry airmass in the
sub-cloud layer should prevent any of this precipitation from
reaching the ground. Otherwise, cool temperatures continue this
afternoon as highs top out in the 60s. Calm winds and clear skies
overnight will result in excellent radiational cooling into the
lower 40s. Very shallow and patchy fog may develop in some
locations. River valleys and southern counties that received the
most rainfall recently are more likely to see fog development.
Our surface high pressure moves off to the east tomorrow. As this
occurs, southerly surface flow and a building mid-level ridge begin
to influence our weather pattern. This promotes a gradual warming
trend through the remainder of the work week. Highs approach the 70s
on Wednesday, climb into the mid 70s by Thursday, before approaching
the 80s by Friday. Alongside this warming trend, continued dry
weather is anticipated. This is despite weak disturbances through
midweek as limited moisture keeps precipitation chances nil.
Heading into this weekend, our weather pattern begins to change. A
digging trough takes shape over the western CONUS towards the end of
this weekend. Several shortwave disturbances are forecast to round
this trough and lift northeast into the central and northern Great
Plains beginning this weekend and continuing into early next week.
At the moment, the main brunt of these systems may remain north of
the area. Despite this, one can count on cooler temperatures and the
return of precipitation chances during this time.
