Area Forecast Discussion
National Weather Service Amarillo TX
1017 PM CDT TUE JUN 21 2016

.Aviation.../For the 06z TAFs/
VFR conditions are expected through the TAF period. Southerly winds
early tonight should gradually shift to southwesterly and persist
through the day. The highest speeds and wind gusts will occur at
Amarillo. Further northwest closer to the surface trough near Dalhart
and Guymon wind speeds will be lighter and eventually back to
southerly and become light during the late afternoon or evening. The
exception may be in/near showers and thunderstorms that form along
the Johnson Mesa and Black Mesa and move eastward toward these two
TAF sites during the evening. The probability of thunderstorms
impacting the terminals is too low for inclusion in the TAFs at this
time.

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.
