Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK

Valid 311200Z - 061200Z

...Synopsis...
A series of mid-level troughs will continue impacting the Pacific
Northwest and neighboring areas of the western CONUS throughout the
Extended Outlook time frame. This will leave the northwestern
quadrant of the CONUS under periodically strong southwest to
westerly flow into early next week. Embedded disturbances will
continue to move through the persistent troughing and along the
northern periphery of the flattening/displaced upper-level ridge
centered over the southern Plains. This activity will deflect
monsoonal moisture to the south and east, but advect onshore
additional moisture from the eastern Pacific. The general consensus
does favor continued well below normal temperatures across the
western third of the CONUS much of next week along with increasing
chances for multiple days of accumulating rainfall over a good
portion of the Pacific Northwest.

...Northwest, Northern Great Basin, and Northern California...
Dry southwest flow aloft associated with continual troughing over
the northwest CONUS will promote at least a few more days of fire
weather concerns into early next week. 40% Critical probabilities
have been maintained, though the area of concern has decreased in
areal extent on Day 3/Monday, with minor adjustments for Day
4/Tuesday over northeastern CA, northwestern NC, and southeastern
OR. West to southwest winds of 15-20 mph and afternoon RH of 10-20%
will continue elevated fire weather concerns over this region. Below
normal surface temperatures will moderate the threat slightly, but
conditions will remain conducive to wildfire spread until a
significant precipitation event occurs. Increasing potential for
accumulating (widespread wetting) rainfall is introduced
mid-next-week over much of the Pacific Northwest.

...Central and Eastern Wyoming...
Continued above normal temperatures and strengthening drought
conditions are promoting fuel curing across central WY into portions
of western SD. These antecedent conditions will combine with
westerly winds as trough passages continue to result in at least
elevated wind/RH combinations over this region. Both ERCs and BIs
will climb above their respective 90th-95th percentiles, indicating
fuels receptivity is reaching critical levels across the region
where not hampered by significant green up. Additional expansion in
both time and space may be needed if strong southwesterly flow
continues over the area as some forecast guidance indicates.

...Southern Plains...
Over the southern Plains, the continued hot and dry period
exacerbating existing drought conditions will continue. However,
with the surface trough nudging eastward accompanying the center of
the high, the strongest winds combined with the driest surface
conditions will no longer coincide with the driest fuels, removing
the need for critical wind/RH probabilities.
