.SHORT TERM /THROUGH THURSDAY NIGHT/...
Issued at 157 AM CDT Tue Sep 30 2025
At 3AM, high pressure is centered along the Iowa and Illinois
border. Temperatures range from 54 degrees at Monticello to 64
degrees at Dubuque and Cedar Rapids.
Rex Blocking is forecast to slowly shift eastward into the
Middle Ohio River Valley through Thursday night. This will cause
surface high pressure to slowly shift eastward and slowly turn
the winds from easterly today to southerly on Thursday. High
clouds are forecast to slowly increase today through Wednesday
wih a weak trough to our west. High temperatures today and
Thursday are forecast to be in the mid to upper 80s. Slightly
lower temperatures are forecast on Wednesday as cloud cover
thickens and the trough to our west lifts north of the area.
High temperatures are forecast to be in the lower to mid 80s.

.LONG TERM /FRIDAY THROUGH MONDAY/...
Issued at 157 AM CDT Tue Sep 30 2025
The 500 MB flow is forecast to become more zonal this weekend
into next week. A 500 MB trough is forecast to dig into the
Western US this weekend before lifting into the Plains early
next week. This is resulting in the current POPs Sunday night
into Monday morning. Synoptic models do not show much
precipitation during this period but a couple of ensemble
members do show some precipitation. Thus confidence remains low
on both the timing and if any precipitation does occur with
this system.
Temperatures remain well above normal through the weekend with
the potentially the warmest temperatures on Friday and Saturday.
Current high temperatures on Friday are forecast to be in upper
80s to lower 90s. These temperatures are near record high
temperatures for October 3rd.
