Day 2 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
0155 PM CDT Wed Sep 11 2024

Valid 121200Z - 131200Z

...CRITICAL FIRE WEATHER AREA FOR MUCH OF THE CENTRAL INTO THE
NORTHERN HIGH PLAINS...

The forecast remains unchanged. Strong surface winds are still
expected into eastern portions of the Dakotas into eastern Nebraska.
Fuel receptiveness and RH trends will continue to be monitored in
these areas, but current guidance continues to suggest lesser
concerns with eastern extent.

.PREV DISCUSSION... /ISSUED 0205 AM CDT Wed Sep 11 2024/

...Synopsis...
Mid-level troughing will continue to intensify as it crosses the
Intermountain West and overspreads the northern/central Rockies
Thursday. Strong flow aloft will approach the central High Plains as
a lee low quickly deepens. A surface lee trough will trail south
from the developing low, enhancing southerly winds over much of the
Plains. With dry conditions in place, critical fire-weather concerns
are likely.

...Central High Plains...
Southerly surface winds will begin to increase overnight
D1/Wednesday and into early D2/Thursday as upper-level forcing
approaches from the west. Winds should continue to intensify through
the day as the lee trough/low deepen considerably.
South/southwesterly gusts of 20-30 mph are possible along with RH
values below 25%. RH will be less favorable farther east, though
winds will still be strong. Area fine fuels are dry, but should dry
further over the next 24-36 hours, reaching critical levels. With
the potent co*bination of strong winds and low RH likely over
several hours D2/Thursday, widespread elevated to critical
fire-weather conditions are likely.
 
...Intermountain West...
Across parts of western CO/WY, strong southwesterly winds are
expected ahead of the cold front moving out of the eastern Great
Basin. Aided by the strong flow aloft, wind gusts of 25-30 mph are
likely. Dry southwesterly flow and warm temperatures will support
afternoon RH values below 20%. Meteorological conditions are quite
conducive to fire spread. However, area fuels are much less
favorable after recent rainfall. Given the magnitude of the wind and
relatively dry conditions, several hours of elevated to
near-critical fire-weather conditions still appear likely before the
front passes through.
