Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0241 PM CST Mon Nov 18 2024
Valid 201200Z - 261200Z
Fire weather concerns will generally be minimal across much of the
country through the extended period, though regional concerns may
emerge across portions of the Plains mid-week. An active upper-level
regime will persist through the remainder of the week, characterized
by the amplification of the upper trough currently over the Pacific
Northwest in the wake of today's trough ejection into the Plains.
This regime will maintain an unseasonably strong (1000-1005 mb)
surface low across the broader Midwest/Great Lakes region, which
will support several days of windy conditions across the Plains,
Midwest, and the OH River Valley regions. Despite the windy
conditions, widespread rainfall will eliminate fuel concerns for
most locations with the exception of western NE/SD where the
probability of wetting rainfall through mid-week is low. Elsewhere,
upper ridging over the Four Corners and northern Rockies will help
maintain rain chances along the West coast, and dry, but relatively
calm, conditions across the Southwest and southern Plains through
next weekend.
...D3/Wed - Western SD/NE...
Breezy gradient winds are expected again on D3/Wednesday across much
of the Plains. While the strongest winds are expected to reside
across the central Dakotas into the lower MO River Valley, portions
of western SD/NE will likely see 15-20 mph winds. Relative humidity
values are expected to remain somewhat marginal (generally in the
25-35% range) due to cool temperatures, but may fall to near 20% for
some locations. Additionally, recent reports suggest fine fuels are
sufficiently dry to support fire spread. While critical conditions
are possible, the general expectation is for areas of elevated
wind/RH conditions during peak heating hours. Areas further north
and east where winds will be strongest should see limited fire
concerns given recent and/or anticipated precipitation over the next
48 hours.
