Day 2 Fire Weather Outlook  

NWS Storm Prediction Center Norman OK

0221 AM CDT Sun Apr 04 2021



Valid 051200Z - 061200Z



...Synopsis...

The upper-level trough within the Pacific Northwest will progress to

the southeast during the day, Monday. Mid-level winds will intensify

across the central/southern Great Basin into the Southwest. At the

surface, a front will accompany the trough and reach the Four

Corners by the end of the period. Farther east, a surface cyclone

will deepen along the Kansas/Colorado border.



...Central/Southern Great Basin...

Strong mid-level winds along the southern flank of the approaching

trough will overlap an increasing surface pressure gradient ahead of

the front approaching from the northwest. Winds of 20-25 mph will be

possible, particularly in eastern Nevada into western Utah.

Terrain-favored areas will also see higher winds. RH of 10-20% is

likely during the afternoon. While these critical meteorological

conditions will exist, fuels in most locations still appear

marginally receptive to fire spread.



...Southwest and Southern High Plains...

Mid-level winds will also increase across parts of Arizona as a

southern stream jet moves eastward during the day. There is some

question as to the duration of strong surface winds with southern

extent, but most areas into central Arizona will likely see 15-20

mph with locally higher values possible. RH will be similarly low at

10-20%. Given the ongoing drought, there will be areas of dry fuels

even though ERCs are near normal in most locations. Elevated

conditions will likely extend into New Mexico and southeastern

Colorado with the deepening High Plains surface low. Mid-level winds

will be weaker that far east, which should keep the potential for

critical conditions lower.
