Day 1 Fire Weather Outlook

Valid 171700Z - 181200Z
...NO CRITICAL AREAS...
The previous forecast (see below) remains on track. Despite the
development of breezy/gusty surface winds across portions of west TX
this afternoon, near/above-average fuel moisture should limit the
potential for large-fire spread.

.PREV DISCUSSION... /ISSUED 1243 AM CST Fri Jan 17 2025/
...Synopsis...
A strong mid-level jet will progress eastward from the southwestern
US into the Mississippi Valley, resulting in a surface low
developing and translating across the Southern Plains. Dry and gusty
downslope winds are expected across eastern New Mexico into West
Texas, followed by a cold front, with 20 - 30 MPH sustained winds
and sub-20% relative humidity values. While the meteorological
conditions are typically supportive of fire-weather highlights, ERC
fuels guidance indicates that fuels are not particularly receptive
to wildfire ignition or spread at this time. Any threat for wildfire
spread will remain localized.

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1244 AM CST Fri Jan 17 2025
Valid 181200Z - 191200Z
...NO CRITICAL AREAS...
...Synopsis...
Tomorrow (Saturday), a high-amplitude mid-level trough associated
with a cold airmass is forecast to overspread much of the central
and eastern US. This trough will be accompanied by a strong jet
maximum moving southward across the Intermountain West, which will
bring dry and windy conditions to portions of Arizona and New
Mexico. However, with generally cooler temperatures and a lack of
receptive fuels, any fire-weather threat should remain localized.

Day 3-8 Fire Weather Outlook

Valid 181200Z - 241200Z
In the mid-levels, a large upper cyclone will settle over the
eastern 2/3rds of the US as a strong Arctic air mass moves into the
lower 48. Well below-average temperatures and widespread winter
precipitation are expected to negate fire-weather potential through
much of next week. However, the arrival of the Arctic air mass will
allow strong high pressure to intensify over the Great Basin. This
could support offshore flow and the potential for critical
fire-weather conditions over parts of southern CA early next week.
...Southern CA...
As the Arctic air mass intrudes the CONUS, ridging is forecast to
intensify over the eastern Pacific late this weekend through midweek
next week. As a result, high pressure should quickly intensify over
the Great Basin, tightening offshore pressure gradients over
southern CA. A shortwave trough is also forecast to move east of the
upper ridge and deepen as it moves over parts of the Southwest
D5/Mon. Model solutions have come into better agreement showing this
trough potentially forcing strong mid-level flow over parts of
southern CA. Should this occur, strong offshore pressure gradients,
supported by moderate flow aloft could allow for a period of
critical fire-weather conditions, mainly D5/Mon through D7/Wed.
Ongoing very dry conditions, in combination with increasing
potential for moderate offshore winds lend enough confidence to
introduce 40% areas for D5/Mon and D6/Tues. Offshore winds could
extended into D8/Thurs and beyond, but models still show
considerable variability in the evolution of the relevant upper-air
features.
