   ...NO CRITICAL AREAS...

   ...Synopsis...
   A mid-level trough will traverse the Upper Mississippi Valley as a
   weak upper trough meanders along the West Coast tomorrow (Friday). A
   surface low over the Upper Mississippi Valley will encourage moist
   conditions across the Plains, while a benign surface pattern west of
   the Rockies will result in another quiescent day (fire weather wise)
   across the Interior West. Dry low-level conditions may persist over
   the Ohio Valley on Friday. However, like Day 1, the lack of a
   stronger surface wind field should limit the potential for wildfire
   spread.

   Day 3-8 Fire Weather Outlook

   Valid 191200Z - 251200Z

   Shortwave ridging will rapidly build over the western US through
   midweek as an upper low will gradually strengthen over the East. The
   flow pattern will transition to stronger zonal flow through the
   weekend and into next week. The increase in dry/windy conditions
   should support an increase in fire-weather potential.

   ...Northwest and Northern Great Basin...
   With shortwave ridging in place through the remainder of the week, a
   significant warming trend is expected into the weekend. Initially
   dry conditions beneath the ridge will gradually change as mid-level
   moisture will begin to move into the area late D2/Thursday
   continuing through D3/Friday and into the weekend. While details
   remain scant, some chance for isolated thunderstorms appears likely
   across northern CA into southern OR and the northern Great Basin
   into the weekend. A primarily wet mode is expected with PWATS near
   or exceeding 1 inch at times, which should temper already limited
   fuels across the southern Cascades. Still, the low-end potential for
   lightning over the  drier areas could support some risk for
   localized fire-weather concerns through D4/Saturday.

   Stronger westerly flow aloft will return to the area through the
   weekend and into next week as a shortwave trough/cold front and 50+
   kt mid-level jet move onshore. On the lee side of the Cascades and
   into the western Columbia Basin, dry and breezy downslope conditions
   appear likely. This seem especially likely D4/Saturday and D5/Sunday
   where 40% critical probabilities have been added. With fuels
   expected to dry over the preceding days, some increase in
   fire-weather threat is expected despite the limited dry fuels.
   Thereafter, model uncertainty and the potential for rainfall suggest
   fire-weather concerns will be lower.

   ...Eastern US...
   Associated with an upper low and surface cold front moving offshore
   across parts of the Northeast later this week, gusty northwest winds
   and some brief low humidity are possible D3/Friday. Continued dry
   but less windy conditions are also possible within the post-frontal
   air mass into D4/Saturday. The gusty offshore winds and dry
   conditions could potentially support localized fire-weather concerns
   through the weekend given ongoing drought.
