Area Forecast Discussion
National Weather Service Wichita KS
1225 AM CDT Wed Mar 17 2021

.SHORT TERM...(This evening through Friday night)
Issued at 313 PM CDT Tue Mar 16 2021

Main concern and challenge is the severe magnitude late tonight
into midday Wednesday across south central/southeast Kansas.
Upper low over Arizona early this afternoon will move steadily
eastward this evening, before emerging over the southern high
Plains late tonight. Strong elevated low level moisture transport
will occur along/north of a increasingly baroclinic warm frontal
zone near the Oklahoma/Kansas border overnight. While the usual
differences are shown among the short guidance with regard to
moisture quality, even a general compromise would yield elevated
cape values around 1500 j/kg across far southern Kansas late
tonight in the presence of 45 to 60 kts of cloud bearing shear.
If the NAM/RAP are closer in not only showing better moisture and
instability but also bowing the surface further north to the
Kansas/Oklahoma border Wednesday morning, then an increased threat
for damaging winds and even a tornado will exist. So again, there
appears to be a risk for mainly elevated severe with large hail
in the 06z-12z time frame across south central Kansas and the
Flint Hills and then across southeast Kansas in the 12z-18/19z
time frame on Wednesday. A signal for locally heavy rainfall will
also exist across southern Kansas early Wednesday morning.
Otherwise, while a few strong storms will also be possible across
parts of central Kansas late tonight, locations north of highway
50 look to receive an extended period of mainly rain within the
deformation zone around the north side of the upper low as it
moves eastward across the area into Wednesday evening. A mixed
phase or transition to snow is possible in central Kansas
Wednesday night, before the precip ends early Thursday morning.
Little more than a trace of snow accum is expected at this time.
North winds on the back side of the deep tropospheric cyclone look
to reach criteria so will issue a Wind Advisory with this
forecast package along/west of I-135. Drier weather for Thursday,
though temperatures remaining rather cool, then slightly milder
for Friday.

.LONG TERM...(Saturday through Tuesday)
Issued at 313 PM CDT Tue Mar 16 2021

Upper ridge early Saturday will shift east of the area by Sunday
with a moderating/slight warming trend thru the weekend. The
medium range models are still trying to resolve shortwaves within
the developing split upper flow regime through early next week. An
upper trof looks to move into the central Plains by Monday which
should result in modest chances for showers and perhaps some
thunder. Then a stronger upper jet and trof looks to dive south
along the West coast with a closed low forming over Arizona by
Tuesday night. Overall, temperatures should trend close to late
March climo thru the period.

.AVIATION...(For the 06Z TAFS through 06Z Wednesday night)
Issued at 1223 AM CDT Wed Mar 17 2021

Expect flight conditions to deteriorate over the next few hours
with IFR expected in a few hours as colder air spreads south and
rain becomes more widespread. Thunderstorms most likely at KHUT
KICT and KCNU with mainly showers at KSLN, KRSL and KGBD. Winds
are expected to increase with lighter precipitation likely
lingering throughout the day. -Howerton

.FIRE WEATHER...
Issued at 313 PM CDT Tue Mar 16 2021

widespread precipitation and higher daytime humidity levels.

This hazardous weather outlook is for portions of Central Kansas,
South Central Kansas and Southeast Kansas.

.DAY ONE...Tonight

Severe thunderstorms are expected, mainly after midnight, across
south central and parts of southeast Kansas. The main threat will be
large hail up to half dollar size. A threat for damaging winds to 70
mph and a brief tornado cannot be ruled out for locations close to
the Oklahoma border toward dawn.

Locally heavy rainfall can also be expected with some of the more
intense storm cores across southern Kansas. This could lead to
minor lowland flooding.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

Severe storms will also be possible Wednesday morning until about
noon time, mainly across the southern Flint Hills and southeast
Kansas. The main threats will be quarter size hail and wind gusts to
60 mph. A risk for a tornado may exist for locations mainly
southeast of an Iola to Sedan line.

Some of the rain may mix with or change to wet snow Wednesday night
across central Kansas. Little if any snow accumulation is expected
at this time.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may be needed late tonight, mainly across south
central Kansas and the southern Flint Hills.
