Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0314 AM CDT Mon Jul 24 2017

Valid 251200Z - 261200Z

...Synopsis...
Little change to the overall pattern is expected on Tuesday, as a
slow-moving upper trough edges eastward into northern California and
the Great Basin, while an upper ridge remains in place across the
Southwest into portions of the southern/central Plains. At the
surface, a trough will extend across much of the Plains south of a
surface low near Hudson Bay, while high pressure settles into the
Northeast. Generally weak surface features are expected across most
of the West.

...OR/Northern CA eastward into southern MT...
Scattered to numerous thunderstorms are again expected from
OR/northern CA eastward into southern MT, with the slow-moving upper
trough and embedded smaller-scale features remaining in the
vicinity. Thermodynamic profiles are again expected to support a mix
of wet and dry thunderstorms, with perhaps a slight tendency for
greater rainfall potential given gradually increasing moisture with
time and low-level cooling in some areas from repeated rounds of
convection. Given uncertainties regarding the dryness of the
thunderstorms, no critical area has been introduced for the threat
at this time, though there will definitely be a threat of
lightning-induced ignitions in areas where rainfall remains
relatively light.

...Portions of eastern MT into the western Dakotas...
Locally elevated conditions will be possible across portions of
eastern MT into the western Dakotas within a dry post-frontal
airmass. However, winds are not expected to be particularly strong
and confidence in the concurrence of stronger winds and
near-critical RH is too low for an elevated area at this time.
