.SHORT TERM...
(Today and tonight)
Issued at 428 AM CDT Thu Apr 9 2020

The cold front that passed through our area is currently south of
the Red River, though overnight temperatures have been slow to
cool. As of 09Z this morning, central/southern OK and western
north TX were still experiencing relatively warm temperatures in
the 60`s. Cooler temperatures, in the 50`s, have settled into
portions of northern and western OK. With a large surface high
pressure system exiting Canada and over the plains today, winds
should remain out of the northeast with dry conditions. As the
Canadian high drops into the central plains overnight, a surge of
colder temperatures is expected with lows in the mid/upper-30`s
over N. OK and in the 40`s south of I-40.

.LONG TERM...
(Friday night through next Wednesday)
Issued at 241 PM CDT Thu Apr 9 2020

Moisture advection and increasing winds ahead of a trough to our
southwest will result in an increase in shower and thunderstorm
chances, especially Saturday afternoon and night.  Models naturally
differ somewhat on how far east drier air will mix into western
Oklahoma Saturday afternoon.  There will be a capping issue east of
a dryline in the warm sector.  It is certainly possible that most of
the precipitation coverage during this period might be confined
southern Oklahoma or farther south where deeper moisture and jet
dynamics will be.  Also farther north near the synoptic boundary.

A strong cold front will move quickly across the area on Sunday.
Currently, it appears the front will enter northwest Oklahoma
early Sunday morning and move across all but far southeast Oklahoma
by late Sunday afternoon.  Certainly would not be surprised if the
front moved through faster.  Behind the front, very strong northerly
winds will develop.  GFS soundings indicate the potential for
wind gusts in at least the 45 to 50 mph range.

A freeze still appears likely during the early morning hours of
Monday, Tuesday and Wednesday.  Somewhat warmer temperatures may
occur across northern Texas and south central Oklahoma.

Will maintain a chance of a wintry mix across parts of northern and
western Oklahoma, mainly Monday night into the first half of
Tuesday.
