.PREV DISCUSSION... /Issued 241 PM CDT Sun Oct 22 2017/

DISCUSSION...
Have gone a little on the low side of guidance for tonight`s lows.
Light winds and dry air should allow for temperatures to fall
fairly quickly.

Upper level disturbance over the Pacific Northwest has a 140 knot
jet associated with it. This upper level disturbance is expected to
dive southeast into the northern plains and Midwest by Monday night.
Have gone with the stronger winds and cooler temperatures from the
MET guidance as the Panhandles will be placed in the right front
quad of the upper jet.  Plus the upper level disturbance intensifies
into a closed low, so this will help to bring colder air southward
into the area.

Speaking of colder air, another strong short wave trough is expected
to swing southeastward out of Canada and into the central U.S. by late
in the week which will open the door for much colder air to move
into the area. Some light wintry precipitation may be found behind
the cold front Thursday night into Friday, mainly across the
western Panhandles.

Temperatures will then slowly rebound toward the end of next
weekend.
