Day 1 Fire Weather Outlook

1258 AM CDT Thu May 07 2026
Valid 071200Z - 081200Z
...Synopsis...
An upper-level trough and attendant strong mid-level southwesterly
flow will progress eastward into the eastern CONUS today. A related
cold front and associated rainfall will near the Southeast Coast by
this afternoon. Elevated west to southwest winds south of the
advancing front amid low relative humidity and dry fuels will bring
a fire weather threat to portions of FL today. An upper ridge
building over the western U.S. will promote warm and dry conditions
across the region today.
...Florida Peninsula...
West to southwest winds of around 10 mph with higher gusts across
northern FL will evolve within a tightening pressure gradient
manifested by an advancing cold front to the north. Near record high
surface temperatures within a dry and well-mixed boundary layer
reaching the lower to middle 90s F, will promote afternoon RH of
25-35% across inland and eastern portions of the FL Peninsula.
Numerous active wildfires are present across northern FL amid a very
dry and drought stressed fuelscape. The dry conditions combined with
an emerging steady west to southwest wind late morning through the
afternoon will support an Elevated fire weather threat in portions
of northeastern and east-central FL Peninsula.

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1259 AM CDT Thu May 07 2026
Valid 081200Z - 091200Z
...Synopsis...
An upper-level trough shifts off the Eastern Seaboard into the
Atlantic today as a trailing, lower amplitude upper wave enters the
Midwest and Central Plains. At the surface, showers and thunderstorm
development near a stationary frontal boundary will extend eastward
from Texas along the northern Gulf Coast and FL Panhandle, bringing
some relief to portions of northern FL. Warm and dry conditions
under a building ridge across the western U.S. will manifest largely
as a fuel curing/drying event west of the Continental Divide.
...Northern Plains...
Broad northwest flow aloft will encompass much of the central and
northern Plains Friday, with troughing across the eastern U.S. and a
building ridge over the Intermountain West. Lack of significant
rainfall over portions of ND and eastern MT has allowed more
receptive fuels to emerge over the last few weeks. West/northwest
winds of 15-20 mph and relative humidity falling close to 20% will
combine with increasingly dry fuels to promote an elevated fire
weather concern for portions of the northern Plains. Elevated
Highlights were introduced across far northeastern MT into western
ND to account for this fire weather threat. A temporary improvement
in fire weather conditions is expected late Friday and Friday night
as a cold front shifts south from Saskatchewan. A few showers and
initially high based thunderstorms are possible Friday afternoon and
evening, but widespread wetting precipitation unlikely.

Day 3-8 Fire Weather Outlook

0427 PM CDT Wed May 06 2026
Valid 081200Z - 141200Z
Upper troughing will extend along the eastern U.S. and persist
through early next week as an upper-level low over eastern Canada
remains anchored. This pattern will encourage unsettled weather and
repeated chances for precipitation across portions of the Southeast
to the Mid-Atlantic. Therefore, broader fire weather concerns may
temporarily be dampened for much of the eastern U.S. through the
duration of the forecast period, given a widespread transition to
green-up and expected appreciable precipitation.
An upper ridge will prevail across the western U.S. through the
forecast period. This pattern may result in a curing event, given
above normal temperatures and dry conditions to persist for much of
the Intermountain West. However, timely green-up phase of fuels and
lighter winds should keep concerns low through early next week.
Localized fire weather concerns may emerge in terrain-favored areas
where stronger winds overlap dry fuels.
Between western U.S. ridging and troughing to the east, broad
northwesterly flow over the High Plains and Upper Midwest is
expected to promote sporadic dry and windy conditions atop drying
fuels. Uncertainty in medium-range guidance precludes critical
probabilities at this time, however, fire weather potential should
become more evident in future outlooks.
