Day 2 Fire Weather Outlook  

NWS Storm Prediction Center Norman OK

0209 PM CDT Thu Apr 09 2026



Valid 101200Z - 111200Z



...Afternoon Update...

No changes were made to the previous forecast. In eastern UT and

western CO, seasonably warm temperatures and low RH on Day

1/Thursday will promote short-term fuel preconditioning for Elevated

fire weather conditions on Day 2/Friday. While mid and high level

clouds are expected to increase across the risk area throughout the

day, very low RH of less than 15 percent and southerly winds of

15-25 mph (gusts up to 35 mph) atop dry fuels will maintain broader

fire concerns. 



Farther east, portions of northern KY and southern OH may experience

locally elevated fire weather conditions for a few afternoon hours.

Ahead of an approaching cold front, westerly sustained winds of up

to 10 mph (gusts of 15-20 mph) combined with RH dropping to near 35

percent are expected to overlap a region of drying and potentially

receptive fuels. ERCs in northern KY are approaching the 97th

percentile as 10-hr and 100-hr fuel moistures are forecast to be

within the 10th percentile. While winds will shift out of the north

with the late afternoon cold front arrival, increasing moisture and

decreasing wind speeds into the evening hours should provide some

relief to the fire environment, precluding the introduction of

elevated highlights.

.PREV DISCUSSION... /ISSUED 0141 AM CDT Thu Apr 09 2026/



...Synopsis...

A large upper-level trough approaches the California coast on

D2/Friday as another upper trough traverses the Great Lakes into the

Northeast. Simultaneously, upper ridging will persist across the

Rockies and eastern Great Basin, with zonal flow continuing across

the Great Plains. At the surface, a slow moving cold front will

progress southeastward across the Ohio River Valley and Northeast

with high pressure building into the Great Lakes/Midwest.



...Portions of the Great Basin...

A tightened surface pressure gradient will favor sustained southerly

winds of 15-25 mph across much of the eastern/southern Great Basin

on D2/Friday. Despite some mid/high cloud cover, RH values are

forecast to fall to 15-20% (locally down to 10%) during peak mixing

Friday afternoon. With preconditioned, drying fuels from

D1/Thursday, this combination of winds and RH is expected to support

elevated fire weather conditions across much of eastern Utah into

west-central/northwestern Colorado. Deep boundary layer mixing and

modestly strong mid-level flow (25-35 kts within the 700-500 mb

layer) will also support the potential for occasional gusts to 35

mph across this region. Expected precipitation arrival on Saturday

may provide relief to any ongoing or new fire starts.
