Area Forecast Discussion
National Weather Service Amarillo TX
641 PM CDT THU AUG 25 2016
.AVIATION...
A widespread area of showers and thunderstorms will continue to lift
north and east through tonight. AMA stands the best chance of showers
and thunderstorms during the evening, with a less chance at DHT and
GUY. Low clouds in the lower end of the MVFR range should spread
across all of the TAF sites overnight. Low clouds will then break up
by late in the morning on Friday. Easterly winds will gradually swing
around to the south by late in the morning on Friday.
&&
.PREV DISCUSSION... /Issued 256 PM CDT THU AUG 25 2016/
DISCUSSION...
A stationary front across the southeast Texas Panhandle may serve as
a focus for additional shower and thunderstorm development. Upper
level flow is parallel to this front, so training storms will be
likely in the southeast Texas Panhandle. Therefore, have gone ahead
and issued a Flood Watch for this area. Heavy rain producing
thunderstorms will be possible across other parts of the panhandles
overnight, but they do not look to be as well organized as in the
southeast. An elongated upper level trough over eastern New Mexico
will slowly lift northeast across the area overnight, so would
expect showers and storms to persist.
Chances of rain fall off a little on Friday for the panhandles as
the upper level trough moves off to the east. However, stronger
winds aloft will move across northern areas, so shower and
thunderstorm chances will be best there.
The flow aloft will remain out of the southwest through the first
half of next week. This will bring several upper level disturbances
and subtropical moisture over the panhandles. This should allow for
daily chances of showers and thunderstorms. By mid week next week an
upper level ridge will start to move over the area, so this may
diminish chances for rain a little.
