Area Forecast Discussion
National Weather Service Amarillo TX
207 PM CST Tue Nov 21 2017

.DISCUSSION...A cold front is pushing through the Panhandles this
afternoon, with virga showers associated with parts of the front
with the best lift. Winds have been out of the north to northeast
at around 20 to 30 mph with higher gusts, but the atmosphere
should decouple around sunset with winds tapering off heading into
the overnight hours. As a result of the lower winds, along with a
1035mb high pressure area approaching the area, overnight low
temperatures this evening should drop into the upper 20s to lower
30s. A warming trend will be in store with high temperatures in
the 60s tomorrow, 60s and 70s on Thanksgiving Day, and in the 70s
to near 80 by Friday. We could not ask for a better conditions, as
even the Chamber of Commerce would be pleased with our
Thanksgiving weather forecast. Beyond Friday, periodic dry cold
fronts will move across the region on Saturday and on Tuesday,
with intervening warming trends in between. Unfortunately, as will
be pointed out in the fire weather discussion, dry conditions will
prevail through at least Tuesday of next week.

.FIRE WEATHER...
Ongoing breezy conditions behind a passing cold front should start
to decrease around sunset this evening, with appreciable relative
humidity expected tonight and early tomorrow morning. Though
conditions will be dry through Tuesday of next week, there is a
chance for elevated fire weather conditions on Friday or Monday
ahead of passing cold fronts. The main limiting factor for each of
those days at the moment could be wind speed (which barely
approach elevated thresholds) and relative humidity (near 20
percent). Fuels, regardless of conditions, should remain readily
available to burn as a result of continued dry conditions.

.AVIATION...Previous Discussion...
18z TAF Issuance:

VFR conditions expected with perhaps some mid to high level virga
producing clouds along main cold front as it shifts south. North
to northeast winds will prevail through 00z at 20-25 knots with
occasional gusts up to 34-38 knots. Winds will quickly subside
around sunset and become light and variable as surface high
pressure advances into the area. Winds will then resume out of the
southwest at 10-15 knots towards the end of this period.
