Day 1 Fire Weather Outlook 
NWS Storm Prediction Center Norman OK
0952 AM CDT Sat Oct 26 2024

Valid 261700Z - 271200Z

The Elevated area in the Northeast was expanded slightly west/north
based on the latest observations and high-resolution forecast
guidance. The Elevated area in Wyoming was expanded northward for
similar reasoning. Locally elevated conditions may also develop
along the Sierra Front and eastern slopes/vicinity of the southern
Cascades as southwest/cross-mountain flow strengthens.

.PREV DISCUSSION... /ISSUED 0153 AM CDT Sat Oct 26 2024/

...Synopsis...
Strong ridging and high pressure will intensify over the US today as
a cold front exits off the East Coast. Increasing flow aloft over
the West will support the development of modest lee troughing and
downslope flow over the Front Range, while offshore flow is expected
over the Northeast. Areas of gusty winds and low humidity will
support elevated fire-weather potential today.

...Lee of the Rockies...
Elevated fire-weather conditions are expected for a few hours this
afternoon with gusty downslope winds across parts of WY. Gusts to
15-20 mph and RH below 20% are likely atop dry fuels. Gusty winds
may also occur farther east over parts of the Dakotas and NE near
the surface lee trough. However, afternoon humidity values here
should be higher, supporting only sporadic elevated fire-weather
potential.

...Northeast...
Breezy offshore winds and dry surface conditions are expected
through much of the day today across parts of the Mid Atlantic and
East Coast. A strong offshore pressure gradient and increasing
northwesterly flow aloft will support gusts upwards of 15 mph with
RH of 25-30% within the post-frontal air mass. The co*bination of
several hours of favorable dry/windy conditions and record high
fire-danger indices will support elevated to critical fire-weather
concerns, especially over parts of NJ and CT/MA. Here, a few hours
of locally critical conditions are also possible with lower relative
humidity and recent fire activity.
