620 PM CDT TUE JUN 21 2016

.Aviation.../For the 00z TAFs/
Latest winds at Dahlart are 20015KT. This should show up on the next
METAR as maintenance is now complete. At all three sites winds hould
become more southerly and gusts will diminish shortly. Winds will
then veer to southwesterly by morning and increase with some gusts
possible during the warmest part of the day. Thunderstorms drifting
in from the high terrain along the Johnson Mesa and Black Mesa
should remain west of Guymon and Dalhart through 00z but may approach
shortly after. Will address this possibility in the 06z TAF
issuances. Otherwise VFR conditions are expected to prevail.

Discussion...
No weather to speak of in the near term other than hot conditions on
Wednesday, with many locations reaching 100 degrees fahrenheit.  At
this time, it does not appear that heat advisory thresholds will be
met, with the possible exception of Palo Duro Canyon floor.

Have retained idea of chances for thunderstorms beginning Wednesday
afternoon in the northwest part of the forecast area, as frontal
boundary edges into the area.  Pops continue through primarily
northwest and northern sections, as old boundary remains in the area.

Deep, rich moisture will be in place in an a regime of weak flow
aloft with moderately strong southerly 850 flow.  A few
perturbations in the flow aloft Thursday and Thursday night may
provide forcing to enhance precipitation production.

Following a lull in precipitation chances Friday night, low pops in
all periods thereafter as slow transition to northwest flow occurs.
