.DISCUSSION...
Issued at 122 PM CDT Fri Sep 5 2025

Light rain continues south of I-70 this afternoon. Generally,
only a few hundredths to a tenth of an inch is expected. After
the rain moves out, surface high pressure builds in. Light wind
and clear sky will allow temperatures to fall quickly into the
40s overnight. Fog may develop with dewpoint depressions near
zero. Manhattan and areas to the west and south are most favored
to see some fog. A slow but steady warm-up is forecast into next
week with highs eventually rising back to near 90 by Wednesday.
The next chance of rain arrives Monday into Tuesday as northwest
flow aloft brings a weak mid-level wave overhead and southerly
surface wind brings additional moisture back into the region.
Models differ on the evolution of the weather pattern for the
later half of the week with varying ideas on how amplified and
far east an upper-level ridge builds in. There may be several
more low chances for rain through next week depending on where
the ridge sets up.

.AVIATION /00Z TAFS THROUGH 00Z SATURDAY/...
Issued at 618 PM CDT Fri Sep 5 2025

Predominantly VFR conditions expected. Clearing skies this
evening and overnight will favor some shallow fog development
early Saturday, but elevated winds just off the surface could
keep fog more patchy in nature. Any fog will burn off shortly
after sunrise with VFR conditions through the rest of the period.
