Hail and Damaging Winds in Kansas, June 25, 2019

Area Forecast Discussion

...Update to aviation forecast discussion...

.SHORT TERM...(This evening through Wednesday)
Issued at 321 PM CDT Tue Jun 25 2019

Trends over the next several hours remain the main challenge. A very
weak boundary remains near I-80 in central and eastern Nebraska with
modest south to southwest winds bringing dewpoints in the middle to
upper 60s into eastern Kansas. Cumulus fields have been quite
limited so far though there is some recent better development near
the KUEX radar. The increasing instability is under modest height
rises as remnant cirrus moves across eastern Kansas.

Model signals continue to vary but the persistent trend has been for
lesser activity than the means suggested 24 hours ago. The main
focus continues to be on the boundary, but decreasing CIN may still
allow for isolated development south into the warm sector. If storms
can form, there remains to be moderate shear and strong instability
to support severe storms, with large hail and perhaps wind, with the
non-zero chance for a tornado isolated supercells. Flash flood
potential remain modest with little opportunity for training. Any
convection should dissipate from late evening on with modest low-
level jet and increasing cap strength on modest mid-level WAA.

For Wednesday, the environment over southeastern locations returns to
one of moderate to high CAPE and limited CIN though forcing for
ascent looks rather sparse as heights continue to rise and will keep
any mention out. Continued lower-level WAA as well leads to
slightly warmer temps.

.LONG TERM...(Wednesday night through Tuesday)
Issued at 321 PM CDT Tue Jun 25 2019

The late week to early next week periods continue to feature the
signal for persistent elevated heat and somewhat breezy conditions,
especially in the end of the week in the early weekend. With a
building cap and steadily rising heights, precipitation chances
remain low though non-zero with a moist and humid airmass in place.
There are indications in the central Plains upper ridge weakening
early next week which could bring a boundary into the region and may
bring some chance for convection. 850 mb temps remain on track to
rise into the lower to middle 20s Celsius supporting highs in the 90s
with wet ground conditions keeping dewpoints in the upper 60s to
middle 70s. Heat indices are again expected to peak near 105 on
Friday and Saturday with lesser confidence in the combination of the
heat and humidity beyond this with drying boundary conditions and
lesser mixing as winds back/weaken somewhat.

.AVIATION...(For the 00Z TAFS through 00Z Wednesday evening)
Issued at 626 PM CDT Tue Jun 25 2019

For the 00Z TAFs, have continued with VFR for now. A highly
uncertain situation remains in how far south storms will advance
into the area tonight. Therefore, will continue to monitor trends
as storms propagate down from Nebraska to see if they can get
going deeper into the area. It is possible that storms weaken
before getting into the terminals and be in the form of showers
which would be sometime after 03Z.
