Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1025 AM CST Thu Jan 19 2017

Valid 201200Z - 211200Z


Ongoing forecast is on track with no changes needed.  A broad area
of 25-35 mph westerly low-level flow (with higher gusts) and 25-35
percent RH values will develop in the western half of Texas and
eastern New Mexico during the afternoon and early evening.  A second
day of drying fuels under this synoptic regime may result in
locally/briefly elevated fire weather conditions across the area.
See the previous forecast for more information.

While one mid-level impulse lifts northeast across the central
Plains, another will move onshore the central/southern California
coast. In response, broad cyclonic flow aloft should overspread the
western two-thirds of the contiguous US. The surface pattern will
feature a cyclone lifting northeast from OK towards the mid Missouri
Valley. Farther west, a cold front will push eastward across
southern CA and AZ.

...Portions of the southern Plains...
Related to the central US impulse, a channel of strong
west/southwesterly flow aloft will overspread west TX and much of
OK. This enhanced flow will combine with a tight surface pressure
gradient to encourage southwesterly winds around 25-35 mph
sustained. While these winds may promote some elevated fire-weather
concerns, surface temperatures in the windiest areas will likely
remain in the 50s/60s, as modest cooling aloft occurs. In turn, RH
values are likely to remain above 20-25 percent in most locations.
Considering the marginal state of fuels, these meteorological
conditions do not warrant an elevated area at this time.
