.DISCUSSION...
Main weather highlights today will be a wind shift associated
with a cold front, and at least elevated fire weather conditions
behind the front.

The flow across the U.S. will amplify as a trough moves across
the Midwest and Great Lakes region. This will aid in pushing
colder air over the northern Rockies and Plains southward. Another
upper air disturbance over Montana will move rapidly south today
within north to northwest flow aloft. As a result, rather thick
high clouds will move across the area, especially during the
morning and early afternoon. The clouds may reduce mixing some,
but expect some gusts behind the front will approach 35 knots
during the afternoon (per GFS soundings). Afternoon humidity
should remain between 25-35 percent where winds are expected to
be stronger. This will certainly create elevated to near- critical
fire weather conditions, especially across the southwest 1/4 of
Oklahoma and western north Texas.

Cold surface high pressure will build over the area tonight and
the wind will be much lighter by early Wednesday morning. With a
clear sky and dry air, temperatures will drop to or below freezing
by sunrise. Low 20`s are possible across north central Oklahoma.

On Wednesday, temperatures will be rather cool and the wind will
transition back to the south across part of western Oklahoma.

A warming trend will occur Thursday through Friday with dry weather.
A breezy wind Friday may elevate fire weather conditions across
western Oklahoma.

Another cold front will move across the area late Friday into Saturday.
Near average temperatures are expected behind the front on
Saturday. Warmer and breezy weather is expected Sunday and Monday.
