Day 1 Fire Weather Outlook  

NWS Storm Prediction Center Norman OK

0157 AM CDT Fri May 09 2025



Valid 091200Z - 101200Z



...NO CRITICAL AREAS...



...Synopsis...

Amplified mid-level flow will continue across the CONUS today as a

broad upper low gradually moves eastward. Western US ridging will

also amplify, forcing stronger flow aloft over the northern US. At

the surface, a cold front will move south across the Northern Plains

and Great Lakes. Relatively mild and wet conditions will prevent

broader fire-weather concerns over much of the country, though a few

drier thunderstorms are possible along the cold front.



...Northern Plains and Great Lakes...

As the cold front progresses southward, isolated thunderstorms are

likely to form along and ahead of it through the heat of the day.

With relatively modest moisture (PWAT values around 0.8 inches)

these storms are expected to be relatively high based. A mixed mode

of wet/occasional dry storms is possible with some lightning risk

over recent dry fuels. While coverage of the drier storms appears

limited, increasingly dry and breezy conditions behind the cold

front could allow for some lightning ignitions and localized

fire-weather concerns.

Day 2 Fire Weather Outlook  

NWS Storm Prediction Center Norman OK

0158 AM CDT Fri May 09 2025



Valid 101200Z - 111200Z



...NO CRITICAL AREAS...



...Synopsis...

An upper ridge will shift into the Plains on Saturday, as a compact

shortwave trough exits the Northeast. Beneath the building ridge, an

upper low will meander about the Southeastern US as the mid-level

flow pattern remains blocked. Troughing will slowly deepen over the

eastern Pacific amplifying the upper-level pattern.



...Northern Plains...

Despite the relatively stagnant upper air pattern strong flow aloft

will begin to move over the Ridge across the Rockies and into the

northern US. This will support slow deepening of a lee trough

Saturday afternoon. Low-level winds will veer to southerly and

strengthen through the weekend as dry surface conditions develop.

While widespread critical RH and winds are not expected, a few hours

of southerly gusts of 15-20 mph and RH below 35% are possible. This

appears most likely over parts of the Dakotas and western MN. As

fuels continue to dry, locally elevated fire-weather conditions may

develop. However, the lack of stronger winds and overlap with the

driest fuels should prevent more widespread concerns for Saturday.
