.PREV DISCUSSION... /ISSUED 0147 AM CDT Fri Aug 12 2022/

...Synopsis...
An upper ridge will persevere across the central U.S. while a
mid-level trough meanders along the Pacific Northwest coastline
today. Modest mid-level winds overspreading the Cascades will
support leeside downslope flow and acco*panying Elevated dry/windy
surface conditions into the Harney Basin and surrounding areas
during the afternoon. Deep-layer ascent will aid in the lifting of a
monsoonal airmass across the northern Rockies by afternoon peak
heating, with scattered thunderstorms expected. Several of the
thunderstorms are expected to be wet, and traversing fuel beds that
are highly receptive to fire spread on a spotty basis, precluding
isolated dry thunderstorm highlights. Nonetheless, a localized
threat for fire starts exists given the number of total lightning
strikes that may occur away from precipitation cores, along with the
potential for gusty, erratic winds.

Despite the presence of upper ridging, surface low development is
likely in the northern Plains. Deterministic guidance substantially
disagrees regarding how low RH will drop by afternoon peak heating
along the Nebraska/South Dakota border. However, there is some
signal for at least locally Elevated surface conditions across parts
of the northern Plains, perhaps extending east to the Iowa/Minnesota
border.
