Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0102 AM CDT Mon Jun 17 2019
Valid 181200Z - 191200Z
The stagnant quasi-zonal flow pattern will begin to break down on
Tuesday as marginally enhanced mid-level westerly flow (35-45 kt)
associated with an upper-level jet streak enters the Pacific
Northwest. At the surface, an area of low pressure will develop,
beneath the right-exit/diffluence region of the upper-level jet,
across southern Canada and track into north-central Montana.
Otherwise, dry conditions will persist across southern portions of
the Desert Southwest where winds will generally remain light.
...Columbia Basin Vicinity...
Diurnal heating and vertical mixing of the marginally enhanced
mid-level flow will allow afternoon sustained westerly winds of
15-20 mph to develop as RH values fall into the 20-25% range amidst
fuels that are at least marginally receptive to large-fire spread.
Thus, an elevated fire-weather designation has been introduced for
the region, with perhaps some potential for locally critical
conditions, particularly in terrain-favored locations that can act
to locally enhance wind speeds.
