Area Forecast Discussion
National Weather Service Wichita KS
620 PM CDT Tue Sep 7 2021

.SHORT TERM...(This evening through Friday night)
Issued at 245 PM CDT Tue Sep 7 2021

After the slight chances for late day convection as mentioned
above along the cold front in southeast Kansas, much drier and
somewhat cooler air will advect south across Kansas tonight
through Wednesday. Surface high pressure drifting south from the
northern Plains into mid-America will influence our weather thru
Thursday. Much warmer southerly low level return flow by Thursday
afternoon will support temperatures closer to 90F again across
central Kansas. The upper ridge over the western conus will slide
eastward across the Rockies into the high Plains during Friday.
This will support much warmer temperatures well into the 90s
across central and southeast Kansas.

Darmofal

.LONG TERM...(Saturday through Tuesday)
Issued at 245 PM CDT Tue Sep 7 2021

An upper trof moving from the Pacific Northwest eastward along
the northern tier of states looks to flatten the upper ridge over
the weekend. This may allow a weak cold front to slip as far south
as northern Kansas, before retreating north again by early
Monday. There is still enough spread among the medium range
operational models and ensemble solutions into early next week
with the regard to the mean flow and any potential for a
significant cool down or precip chances, which looks doubtful at
this time. So will keep the forecast dry with temperatures above
climo.

.AVIATION...(For the 00Z TAFS through 00Z Wednesday evening)
Issued at 619 PM CDT Tue Sep 7 2021

VFR conditions are expected for the most locations over the next 24
hours. The only exception will be along a sharp cold front currently
moving across southern and southeast KS. Isolated convection may
develop along the front primarily for areas east of the KS Turnpike
along a pre-frontal trough.  If a storm can get going and affect the
KCNU taf sight, some MVFR vsbys may occur with the TSRA.  For now,
uncertainty on KCNU being affected by a storm is high, so will only
mention a VCTS at KCNU for a few hours this evening.

The cold frontal boundary will push into nrn OK in the next few
hours bringing the storm chances to an end, with north winds
dominating the pattern into Wed.
