Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1013 AM CDT Thu May 05 2022
Valid 051700Z - 061200Z
The Elevated risk area is expanded southward to enco*pass portions
of the Sacramento, Guadelupe, and Davis mountain ranges in southern
NM/southwest TX. Latest surface observations already show RH values
near 15% with further reduction likely by late afternoon amid deep
boundary-layer mixing. Relatively benign winds at the moment will
increase through the day as stronger mid-level flow at around 20-25
mph mixes down to the surface within, and in the lee of, the higher
terrain. Persistent elevated conditions appear likely, and
brief/localized critical conditions are possible. The forecast
regarding central NM and portions of southern NV remain on track.
See the previous discussion below for details.

.PREV DISCUSSION... /ISSUED 1226 AM CDT Thu May 05 2022/
...Synopsis...
The central/southern Plains mid-level trough will continue its slow
progression eastward today. Across the West Coast, broadly cyclonic
flow will exist with a strong upper-level jet across the northern
Sierra. At the surface, fire weather concerns will be driven by weak
surface trough development in the Great Basin and in eastern New
Mexico.
...Central New Mexico...
Mid-level winds will be decreasing during the day. However, they
will be sufficient to induce a weak lee trough in the eastern
plains. Winds of 15-20 mph with perhaps some higher speeds in
terrain-favored areas. Dry air will once again be present with
afternoon RH falling to 10-15%.
...Southern Nevada...
Temperatures in the upper 80s to low 90s F will support afternoon RH
of 10-20% across much of Nevada. A weak surface trough in the Great
Basin will promote 15-20 mph winds. Elevated fire weather concerns
will exist where fuels have sufficiently dried.
