Day 2 Fire Weather Outlook

Valid 211200Z - 221200Z
...NO CRITICAL AREAS...
...Synopsis...
A strong midlevel westerly jet streak will cross the northern
Rockies during peak heating, while a related cold front overspreads
the region. This will promote strong, post-frontal westerly surface
winds across portions of northern MT, which could briefly overlap
20-30 percent RH. As a result, locally elevated fire-weather
conditions are possible.
Farther east, the southern periphery of a belt of strong deep-layer
northwesterly flow will overspread MN, WI, and Lower MI.
Boundary-layer heating and related mixing into the enhanced flow
aloft will yield breezy/gusty surface winds amid 25-35 percent RH.
While locally elevated conditions are possible, uncertainty
regarding fuels and marginal winds/RH limit confidence in the
large-fire threat.
Lastly, locally elevated conditions are possible over portions of
east-central FL during the afternoon, where diurnal heating amid
enhanced deep-layer westerly flow should favor breezy/gusty surface
winds and around 30 percent RH. Overall, these conditions appear too
localized for an Elevated area at this time.
