Area Forecast Discussion
National Weather Service Topeka KS
311 PM CDT Sun Aug 13 2023

.DISCUSSION...
Issued at 311 PM CDT Sun Aug 13 2023

Key Points:

- Strong to severe storms possible this afternoon/evening.

- Cooler to begin the work week before warming up into the weekend.

A trough currently over the Dakotas continues its southeastward
progression this afternoon with an associated surface cold front
located across central/eastern Nebraska into western Kansas.
Isentropic ascent has led to persistent warm-advection showers
and storms this morning and into the afternoon which has limited
destabilization of the atmosphere for the most part. Skies are
beginning to clear across the area, but the degree of
destabilization that will occur remains uncertain especially with
eastward extent. To add to the complexity, several outflow
boundaries remain parked across the area along with a warm
front/differential heating boundary encroaching on the I-35
corridor. These boundaries are leading to localized areas of
convergence seen in satellite by areas of agitated CU.
Redevelopment is possible along these boundaries given the mostly
uncapped environment and increasing instability. Hodographs are
elongated, but mainly straight in nature, so damaging wind gusts
and large hail look to be the main threats. Storm interactions
with remaining boundaries could locally enhance storm-relative
vorticity and lead to a brief spin-up, but this appears to be a
low probability. Additional convection is expected along the cold
front, but lesser CAPE in this area leads to uncertainty in how
robust convection will be and how much of the forecast area will
be impacted. Best chances for severe storms will be if storms
congeal into bowing/line segments with damaging winds being the
main hazard. While the flooding risk appears low considering the
progressive nature of storms, PWATS around 2" could lead to
isolated flooding if one area is impacted by several rounds of
storms.

Any storms clear the area overnight as northwest flow ushers in
cooler and drier air to begin the work week. Breezy northwest winds
on Monday will keep temperatures in the 70s to low 80s. Some
guidance indicates stratus building into northeast Kansas during the
daytime hours which could keep temperatures cooler depending on how
far southwest these clouds reach. A surface ridge builds overhead
for Tuesday and shifts east of the area for the middle of the week
allowing for the return of WAA and climbing temperatures into the
weekend; highs are forecast to be in the triple digits again
Saturday and Sunday.

&&

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 1240 PM CDT Sun Aug 13 2023

Showers and a few storms have persisted into this afternoon and
have complicated the forecast for any additional storms this
afternoon/evening. Confidence has lowered in TS impacting sites
later today; have included VCTS, but there is a chance storms
remain away from terminals. Winds shift to the north-northwest and
strengthen behind a front this evening and into Monday. Some
guidance indicates a MVFR stratus deck building in Monday morning,
but confidence is too low for inclusion.

NONE.
