.DISCUSSION...
Issued at 130 PM CDT Thu Sep 25 2025
The main weather theme over the next week will be dry conditions
with above normal temperatures. Visible satellite shows a few
clouds over the state with surface high pressure centered over
Nebraska sliding southward. Patchy to isolated fog may develop
tonight with a focus over eastern into southern Iowa where the
winds will be lightest. Friday through early next week the
positively-tilted trough stretched from the eastern Great Lakes
to the southern Plains splits off a closed low over the
Southeast US on Friday. This will set up a slow pattern as an
omega block takes shape with the low over the Southeast US,
which may evolve with AL94 early next week, a closed low moving
over California to the Four Corners region, and a ridge
in between over the central US. A shortwave trough moving over
the Canadian prairies will send a moisture starved cold front
into the state around Saturday, but with little if any change in
the sensible weather. By the middle of next week, the ridge top
will start to lean eastward allowing for more southwesterly
flow by later into next week. This may open up opportunities for
an increase in moisture and the chance of precipitation. Until
then, dry weather with highs ranging from around 80 degrees to
the middle 80s will occur on any given day.
