Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0211 AM CDT Sat May 10 2025
Valid 111200Z - 121200Z
...Synopsis...
Mid-level ridging over the Rockies will begin to move eastward as
strong southwesterly flow and troughing move onshore in the West. A
lee low and surface trough will aide strong southerly winds over
much of the Great Plains, while a cutoff low and cool/wet conditions
persist to the east. Several hours of dry and breezy conditions will
support widespread elevated to near-critical fire-weather potential
over the Plains Sunday.
...Northern Plains and Midwest...
As the ridge over the northern US shifts eastward, stronger flow
aloft will overspread the Rockies deepening the lee trough. A broad
surface cyclone should emerge, aiding in strong southerly winds over
much of the Plains. Sustained at 15-20 mph with gusts to 25 mph,
winds will overlap with temperatures 20-30F degrees above normal.
Several hours of lower RH below 30% is expected. This should support
widespread elevated fire-weather conditions from NE and the Dakotas
to western MN and parts of IA.
Near-critical conditions may also occur where the stronger winds
interact with areas of locally lower RH and drier fuels for several
hours Sunday afternoon. This appears most probable over parts of
western MN and central NE. However, confidence in widespread
sustained critical conditions is lower owing to marginal RH values.
No critical areas were added, though this may change in subsequent
outlooks with updated guidance.
