Day 1 Fire Weather Outlook 
NWS Storm Prediction Center Norman OK
1126 AM CDT Fri Nov 01 2024

Valid 011700Z - 021200Z

The primary changes made to the Day 1 Fire Weather Outlook Update
was to expand Elevated highlights into southern Pennsylvania, and
northeast to portions of coastal New England. In these areas ahead
of the cold front, clearing skies are leading to rapid
boundary-layer mixing and lowering of RH. Sustained surface winds
are already reaching 20 mph in spots, with higher gusts, and
short-range guidance consensus suggests that RH should drop to 30-35
percent RH by mid-afternoon. As such, Elevated fire weather
conditions remain likely given the presence of dry fuels.

.PREV DISCUSSION... /ISSUED 0158 AM CDT Fri Nov 01 2024/

...Synopsis...
On the backside of a midlevel trough tracking east-northeastward
across the Northeast, deep tropospheric drying will occur across
portions of the Mid-Atlantic behind a related cold front. A tight
pressure gradient and enhanced low-level flow will yield 15 mph
sustained westerly surface winds (with gusts upwards of 25-30 mph).
These winds will overlap 25-35 percent RH behind the front during
the afternoon, and given very dry fuels across the region (90th
percentile ERCs), a few hours of elevated fire-weather conditions
are expected. While there will be some potential for isolated
early-day showers along the front, this activity should be too light
and/or isolated to have an appreciable impact on the receptive
fuels.
