Day 1 Fire Weather Outlook

0140 AM CDT Mon Aug 21 2017

Valid 211200Z - 221200Z


Upper ridging will continue to amplify across much of the western
CONUS today as a weak upper low remains off the coast of
central/southern CA. Farther east, a shortwave trough will dig
southeastward from the Canadian Prairie provinces into the northern
Plains and Upper Midwest by tonight. At the surface, some increase
in northerly post-frontal winds will occur across parts of eastern
MT into the western Dakotas and northeastern WY this afternoon.
However, RH values are forecast to become only marginally lowered,
which precludes the introduction of an elevated area at this time.
