Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1153 PM CDT Sun Apr 23 2017

Valid 241200Z - 251200Z


As an upper trough amplifies across the Four Corners region into the
southern Rockies, strong low/midlevel flow will spread from AZ
eastward into portions of NM and the southern High Plains in
conjunction with deepening low pressure in the lee of the Rockies. A
critical fire weather threat will result across portions of AZ, NM,
and west TX.

...Portions of AZ/NM and the adjacent Four Corners Region into West
Very warm and dry conditions are expected across AZ/NM, the adjacent
Four Corners region, and west TX this afternoon, with max
temperatures in the 70s-80s F expected at higher elevations and 90+
F expected at lower elevations. Minimum RH values of 5-15% in
conjunction with sustained westerly winds of 20-30 MPH will result
in critical fire weather conditions across eastern AZ, much of NM
and far west TX. Elevated conditions will extend into the Four
Corners region and also into a larger portion of the OK/TX
panhandles and west TX.

...Portions of the Upper Midwest/Upper Mississippi Valley...
A strong low-level jet is expected to support strong and gusty
surface winds across portions of the Upper Midwest and Mississippi
Valley regions. High cloudiness may limit the amount of heating that
occurs in this area, but with a very dry residual airmass in place,
a modest amount of warming will result in elevated fire weather
conditions where dry fuels are available. An elevated delineation
may be required in the Day 1 update depending on short-term
observational trends.
