PREV DISCUSSION... /Issued 343 AM CST Mon Feb 20 2017/

DISCUSSION...
Dry forecast continues through Sunday.  Thursday expected to be
windy with critical fire weather conditions.

Sharp 500 mb shortwave trof currently over western part of
forecast area expected to progress eastward today.  Associated
weak polar cold front will move through the Texas and Oklahoma
Panhandles this morning, with breezy north winds in its wake.
Lingering morning clouds expected to clear eastern sections early
this morning.

Above-normal daytime temperatures expected through Thursday as dry
trajectories allow ample insolation.

Next digging shortwave trof crosses the Rockies on Thursday, with
rapidly falling pressures creating windy conditions across the
Panhandles.  Strong west winds during the day will cause Thursday
high temperatures to be about 25 degrees Fahrenheit above normal.

Polar cold front associated with this system passes Thursday
night, bringing highs on Friday close to climo.  Modest
temperature recovery commences on Saturday.  03

FIRE WEATHER...
Elevated fire weather conditions are expected this afternoon
across all of the Texas and Oklahoma Panhandles due to dry north
winds.

Southwest winds on Tuesday will not be strong enough to
cause elevated or critical fire weather conditions.

Critical fire weather conditions are likely to develop area-wide
on Thursday as a rapidly deepening low pressure trof sets up
across the eastern part of the forecast area. Deep west winds are
expected to mix to surface, aided in part by 500 mb winds above 60
knots overhead.

Briefly elevated fire weather conditions are expected during the
afternoons across western sections of the Panhandles on Wednesday,
Friday and Sunday as westerly winds increase into the 15 to 20 MPH
range.  03
