...Synopsis...
Fire weather concerns will linger in parts of the Great Basin and
central Rockies for the remainder of the weekend. A modest frontal
passage in the wake of Saturday's mid-level wave will induce
westerly winds across much of the northern Great Basin and northern
Rockies. This will support areas of fire weather concerns after
several days of hot, dry weather. Additionally, a weak monsoonal
surge will support isolated dry thunderstorm chances across parts of
UT where fuels are receptive.
...Idaho into Wyoming...
Westerly post-frontal winds are expected to increase to 15-20 mph
from the upper Snake River Plain in southeast ID into the Wyoming
Basin. Despite slightly cooler temperatures on Sunday afternoon, dry
air will remain in place and support another day of 10-20% RH.
Consequently, elevated (to perhaps locally critical) fire weather
concerns appear probable. Fine fuels across the region continue to
dry and are expected to be sufficiently cured by Sunday afternoon to
support the fire weather threat.
...Utah/Dry-Thunderstorms...
The upper-level ridge is forecast to gradually shift east over the
next 48 hours, which will allow for a weak surge of monsoonal
moisture northward through the southern CO River Valley into AZ/UT
by Sunday afternoon. Although the quality of mid-level moisture
remains uncertain, several forecast soundings show adequate
instability and deep, dry sub-cloud layers supportive of dry
thunderstorms. Convection is possible across adjacent areas of AZ
and CO, but the dry-thunderstorm risk area is confined mainly to
portions of UT where fuels are expected to be most receptive.
