...CRITICAL FIRE WEATHER AREA FOR CENTRAL/EASTERN NV...
A vigorous upper trough is forecast to amplify and shift eastward
across the Pacific Coast into the Great Basin/interior Northwest by
Monday morning. At the surface, low pressure will deepen from the
northern Great Basin into portions of the northern High Plains, with
a surface trough extending southward into the central/southern High
...Great Basin and vicinity...
As low/midlevel flow increases in advance of the strong upper
trough, a broad area of elevated to potentially critical fire
weather conditions is forecast to develop from the Great Basin and
vicinity eastward into portions of southern WY. High-end critical
conditions are likely over northwest NV and adjacent portions of
northeast CA, southeast OR, and far southwest ID. In this area,
sustained winds of 20-30 mph will combine with minimum RH values of
8-15%, with localized areas of extremely critical conditions
possible. Another area of critical conditions is forecast over
portions of central/eastern NV, where sustained winds of 15-25 mph
are forecast in conjunction with minimum RH values of 10-15%. Poor
overnight RH recovery is expected across both critical areas, and
critical conditions may persist through late tonight in some areas.
Elsewhere, critically low RH is expected over the remainder of the
elevated area, though slightly weaker winds and/or less receptive
fuels preclude any critical upgrade for those regions. Elevated to
locally critical wind/RH will also likely develop across portions of
eastern ID into southwest MT, but fuels are currently expected to be
mostly unreceptive, so no delineation was included for that area.
