.PREV DISCUSSION... /Issued 309 PM CST Wed Jan 18 2017/

DISCUSSION...
Good agreement between models in the near-term regarding mid-level
features. Closed low currently over northeast New Mexico is progged
to lift northeast of the Texas and Oklahoma Panhandles, with next
shortwave trof moving across the area on Friday.  Meanwhile, weak
cold front enters northern parts of forecast area late tonight and
Thursday, with winds becoming northerly in those areas.  Areas of
fog expected to develop late tonight across eastern sections off the
Caprock.

Falling heights with Friday shortwave trof expected to cause windy
conditions to develop, possibly meeting wind advisory criteria across
western sections.

Next shortwave crossing the area late Saturday looks to be stronger,
possibly developing into a closed low, and providing an opportunity
for precipitation as it brings Pacific moisture with it.  Have
retained low pops for snow or rain, bringing at least brief snow
mention into all sections by late Saturday night.  Any amounts look
to be very light.

Another shortwave trof on Tuesday also expected to be mainly a wind
producer, with slight chance pops for light precipitation in northern
sections retained for Tuesday and Tuesday night.  03

FIRE WEATHER...
No elevated or critical fire weather conditions expected due to
relative humidity values remaining above necessary thresholds.  Windy
conditions on Friday and Tuesday may cause an increase in fire spread
potential. 03
