Severe Thunderstorm Warning 188, NWS Amarillo, TX

Area Forecast Discussion...UPDATED

.AVIATION...
For the 00Z TAFs, another round of showers and tstms currently
over the far northwest parts of the forecast area will continue
moving east and southeast, and will likely impact KDHT around 01Z
this evening, and perhaps KAMA later this evening or tonight. Have
incorporated a TEMPO group for KDHT and a VCTS for KAMA to account
for this cluster of showers and tstms. Based on radar movement of
storms, it appears KGUY may not be impacted, and have omitted
tstms from that terminal site. Thunderstorms should diminish in
coverage and intensity late tonight.

.PREV DISCUSSION... /Issued 408 PM CDT Sun Jul 2 2017/

DISCUSSION...
Isolated to scattered thunderstorms expected again this evening,
with convection possibly lingering past midnight in eastern
sections. Convergence zone seen in surface observations just east
of a line from Guymon to Borger is currently experiencing cumulus
development. Dryline-like feature poised near far northwest corner
of forecast area, with thunderstorm development already well
underway. Incoming shortwave trof in weak northwest mid-level flow
will provide support for continued convection this evening as
low-level jet develops.

Moist airmass remains in place Monday, with afternoon and evening
thunderstorms still plausible, owing to another shortwave trof,
with this one possibly driving a weak cold front into the
northwest part of the forecast area.

Low thunderstorm pops Tuesday afternoon through Wednesday night
confined to mainly southern and southeastern sections where better
low-level convergence expected to be positioned near weak frontal
boundary.

Dry thereafter as anticyclonic mid-level flow prevails in response
to strengthening ridge over Rockies. High temperatures mainly in
the mid- to upper-90s
