635 PM CDT Mon May 28 2018

.SHORT TERM...(This evening through Tuesday Night)
Issued at 324 PM CDT Mon May 28 2018

Been a hectic day today, thunderstorms started moving into far
western portions of the CWA early/mid morning, and have been going
since...thus the shorter AFD. In the bigger picture, upper level
flow across the region is south- southwesterly, thanks to low
pressure which continues to spin over portions of UT and a ridge
axis extending north from TX into the upper Midwest. Between a mid
level shortwave disturbance and lower/mid level warm advection
that has been ongoing through the day, convection has continued.
It's a messy surface pattern across the area, the main low is off
to our SW over the southern CO/KS border, but outflow boundaries
from earlier activity shifted south, sparking off/aiding in
thunderstorm development, resulting in more outflow...currently
the NW portions of the CWA has ENE winds, it's much more variable
in speed/direction near the thunderstorms, then gusty and
southeasterly across the southeastern portions of the CWA. This is
all resulting in quite a temp gradient across the area too, with
mid 60s to mid 90s. Models have not had the greatest handle on how
things have evolved, so obviously confidence in anything the rest
of today/tonight is not high at all. The threat for strong/severe
storms will continue through late today, but best chances look to
be mainly confined to the southwestern quadrant of the CWA. The
threat should wane with time this evening/tonight. Kept PoPs
around all evening/night, though they'd more questionable the
further east across the CWA you go.

As we get into tomorrow, there's uncertainty with exactly how much
activity will be ongoing across the area..models suggest best
chances will be across the western half of the CWA. Potential for
esp afternoon/evening severe thunderstorms will return,
instability/deeper layer shear in place once again, but there is
better upper level forcing as the low/SSE-trailing trough axis are
moving onto the Plains. Southern portions of the CWA are included
in the Day 2 Slight Risk.

.LONG TERM...(Wednesday through Monday)
Issued at 324 PM CDT Mon May 28 2018

Due to ongoing convection, little time was spent on the long term
period and saw no reason to make any notable changes to the
blended grids. Overall, have things drying out for Wednesday, with
periodic thunderstorm chances returning Thursday through Sat.
Doesn't look as hot as the past couple of days, highs remain in
the 80s to lower 90s for most days.

&&

.AVIATION...(For the 00Z KGRI/KEAR TAFS through 00Z Tuesday)
Issued at 631 PM CDT Mon May 28 2018

There will be on and off thunderstorms through much of the period
but timing them will be a little bit of a challenge. Winds will be
from the south.
