Area Forecast Discussion
National Weather Service Midland/Odessa TX
1054 AM CDT Thu May 17 2018

.UPDATE...

Morning hi-resolutions models showing a better signal for showers
and thunderstorms this afternoon across much of the area. A
shortwave is already helping produce showers and storms across
Pecos and Terrell counties. We are also heating up much faster
today vs. yesterday with the dryline still across western areas of
our CWA. Current thinking is we will continue to destabilize along
and east of the Pecos River through the afternoon with storms
forming near here around 2 PM CDT or so. These storms will have
the potential to produce large hail and damaging winds. Sent an
update to increase PoPs and keep severe wording.

&&

.AVIATION...
18Z TAF issuance
Southerly winds will continue, gusty at times, through the TAF
period. Thunderstorms are expected to develop this afternoon and
mainly affect KMAF, KFST and KINK. These storms should exit the
area this evening and VFR conditions will prevail into Friday.
