Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0159 PM CST Thu Dec 08 2016

Valid 101200Z - 161200Z

Fast, quasi-zonal mid-level flow will persist across the Lower 48
for much of the extended period.  At the surface, high pressure will
dominate in the east at the beginning of the period, but this high
will shift eastward as a deep surface low over the central U.S.
reaches the East Coast by the D5/Mon time frame.  Upstream of this
low, lee surface cyclogenesis will reoccur given the persistent
upper-level pattern.  The persistent pattern will result in an
extended period of westerly downslope flow in portions of the
Southern Great Plains along with a few periods of increased fire
weather concerns.

...D3/Sat through D4/Sun - Eastern New Mexico and the Texas
Panhandle...
Lower-end/elevated fire weather conditions will likely exist both
afternoons.  This is supported by westerly downslope flow increasing
to 20-25 mph with a few higher gusts as the region remains west of a
lee trough over the Texas Panhandle.  Cool surface temperatures and
marginal RH values will be the primary limiting factors for a higher
fire weather threat as the region should remain dry throughout the
extended forecast period.  40 percent probabilities have been
indicated where the highest fire weather potential will likely
exist.  Marginal fire weather conditions may also extend beyond this
period, but model consistency and questions about RH values not
falling to critical criteria preclude any additional highlights at
this time.
