Day 1 Fire Weather Outlook

...NO CRITICAL AREAS...
...Synopsis...
A generally zonal/low-amplitude mid-level flow pattern will be in
place across the CONUS, with a well-defined impulse poised to eject
into the Plains by afternoon. A moist low-level airmass, along with
scattered to widespread showers and thunderstorms, are expected
across most areas east of the Rockies, which should mitigate
wildfire spread potential. Dry and occasionally breezy conditions
may develop across portions of the Desert Southwest during the
afternoon, though these conditions should be too brief or localized
to warrant Elevated highlights at this time.

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1158 PM CDT Thu Jun 05 2025
Valid 071200Z - 081200Z
...NO CRITICAL AREAS...
...Synopsis...
The upper pattern will amplify to a degree over the central/eastern
CONUS, with a mid-level trough deepening across the northern Plains
into the Great Lakes region as a preceding mid-level trough
traverses the OH Valley tomorrow (Saturday). Like Day 1, a moist
low-level airmass and/or scattered to widespread thunderstorms
across several locales east of the Rockies should limit
wildfire-spread potential. A cold front should sweep across the
northern Rockies/northern High Plains tomorrow afternoon. However,
RH is not expected to dip to Elevated/Critical thresholds. As such,
while a localized wildfire start cannot be ruled out, conditions
appear too marginal to warrant the introduction of fire weather
highlights this outlook.

Day 3-8 Fire Weather Outlook

0244 PM CDT Thu Jun 05 2025
Valid 071200Z - 131200Z
The sub-tropical ridge across the Gulf early in the period will
retrograde toward the western US and then briefly amplify as a
shortwave trough digs southeast across the East. This amplification
will bring a period of warming/drying across the West but the
duration should be brief as the pattern quickly flattens in response
to the approach of a couple of low-amplitude troughs.
This overall pattern will yield cooler and wetter conditions across
much of the eastern US, with at least a short period of warmer,
drier conditions across the West as the ridge amplifies. However,
fuel moisture across the West should be high enough to preclude
widespread critical fire weather conditions.
Late in the period as low-amplitude troughs impinge upon the
sub-tropical ridge, an increase in thunderstorm potential may occur.
Dry thunderstorms will be possible, especially with the first
trough, but the details (timing and location) are too uncertain to
introduce probabilities.
