.DISCUSSION...
Temperatures will be warming up into the 60s today as westerly
flow and warmer air moves over the Panhandles. Winds will be
breezy out of the southwest this morning, then shifting northeast
later today, before turning back to the southeast tonight.
Southwest flow aloft will set up for Sunday and Monday as an upper
level trough over the Pacific Northwest digs down the west coast.
Winds are expected to be in the 20 to 30 mph range with gusts 40
to possibly 50 mph on Sunday and Monday. With temperatures in the
70s this will open the door for Fire Weather issues (See Fire
Weather Discussion).

Next cold front is expected late Monday night into early Tuesday
morning. Timing on this front is still in question, but models
have it very slow moving to possibly stalling over the Panhandles.
This could play havoc for our temperatures on Tuesday afternoon.
Latest guidance suggest that the front will take about 9 hours to
move from the northwest Panhandles, to the southeast Panhandles,
about 2 to 3 times slower than a typical frontal passage with
these Fire Weather patterns.

Colder air will linger over the Panhandles through early Thursday,
before southwest flow returns to the Panhandles. Wednesday will
likely be the coldest day, unless the front on Tuesday speeds up,
and even then if the cold air lingers over the Panhandles, it will
still likely give colder highs on Wednesday. Thursday is set to be
in the 50s as the warmer southwest flow aloft approaches.

By late Thursday into Friday, either a cut-off low or open wave is
expected to set up over the Baja Peninsula, and there is a hint of
moisture that could be transported back over the Panhandles by
early Saturday afternoon. But given our current dry streak and
Saturday being the 8th day of the forecast, we are still currently
dry over the next 7 days.

.FIRE WEATHER...
Strong southwest winds 20 to 30 mph with gusts 40 to 50 mph in
combination with fairly low relative humidities on Sunday will
provide elevated to critical Fire Weather conditions for the
northwest Panhandle area. A Fire Weather Watch is in effect for
Cimarron County as this area is expected to see critical Fire
Weather conditions for several hours. The rest of the northwest
Panhandles are only expected to be elevated.

Monday will be similar to Sunday with temperatures being a tad
cooler for the western Panhandles, but that will keep the relative
humidities up in the upper teens to lower 20 percent range, thusly
only expect elevated criteria on Monday. A cold front passage late
Monday night into early Tuesday could pose problems due to wind
shift if there were to be any ongoing fires.

.CLIMATE...
Well after 126 days the Amarillo Airport finally measured
precipitation. A whole 0.01 of an inch! This happened shortly
after midnight so a trace of precipitation will go down for the
16th of February, with the 0.01" occurring on the 17th. So we
managed to squeeze in an extra day for the record book by a
matter of minutes. But we have dry 7 day forecast in store, so
lets hope we don`t break this record again this year or any time
soon for that matter. Some areas to the southeast picked up
between a tenth and a quarter of an inch, so a little bit of
drought relief for the southeast Panhandles.
