.DISCUSSION...
Issued at 345 AM CDT Sat Sep 27 2025
Water vapor imagery this morning shows a shortwave trof pushing
through the Dakotas and knocking down the ridging responsible
for the warm temperatures across the area over the past few
days. Cutoff lows are evident over SoCal and Huntsville, AL. A
few clouds at 50k feet over MN indicate the location of the
leading edge of the cooler air as of 3am. Surface obs show
winds have turned from the south to the northwest at Albion and
Sioux Falls.
Expect the dry frontal passage to continue southeast through
the course of the morning; Expect it through Norfolk around 4am,
then Lincoln around 9am and Omaha one hour later. Skies should
remain clear today and despite losing three (south) to ten
(north) degrees from the highs of Friday, today should be the
fourth day in a row of above average high temps.
Although there won`t be much for cloud cover, there will be some
elevated wildfire smoke from the Pacific Northwest, especially
after noon today. That smoke should primarily remain above 1500
feet and should have minimal impact at the surface.
.SUNDAY...
As the front continues southeast on Sunday, the surface high
follows along and southerly return flow develops in eastern
Nebraska and western Iowa. The entire area should get back into
the lower to mid-80s as the H5 ridge redevelops.
.NEXT WEEK...
That ridge is expected to linger through the work week with our
weather stuck on repeat. Lower to mid-80s are anticipated each
afternoon for the work/school week as dry weather persists. Fire
danger will be creeping up as fuels cure.
A broad trof is expected to approach the area by Friday / the
weekend with a few different low centers threatening / promising
the opportunity for precipitation and seasonal temperatures.
