NWS Storm Prediction Center Norman OK

1159 AM CDT Tue Mar 25 2025



Valid 251700Z - 261200Z



...Appalachians...

Some expansion has been made to the Elevated area in the southern

Appalachians vicinity, based on the latest observational and

guidance trends. Sustained winds approaching 15 mph at times

combined with RH near/below 30% will result in elevated to locally

critical conditions. See the previous discussion below for more

information. 



...Northern Plains...

An Elevated area has been added from southwest ND into eastern SD.

Dry and breezy conditions (with winds near/above 20 mph and RH

dropping to near/below 30%) will result in elevated to locally

critical conditions where fuels are dry.

...Synopsis...

A broad upper cyclone will remain over eastern US as ridging

intensifies across the east today and tonight. Strong northwesterly

flow aloft will overspread much of the central US and Appalachians.

At the surface, a weak cold front will move south over the Plains,

as a secondary front moves over the central and southern

Appalachians. Dry conditions and occasional gusty winds could

promote some elevated fire-weather potential.



...Northern Plains...

Behind the front over the central US, gusty northwest winds are

possible across parts of SD and NE. A few hours of dry and breezy

conditions will be possible with RH below 30% and wind gusts of

20-25 mph. While the overlap of dry and breezy conditions will be

brief, area fuels are dry and could support some localized

fire-weather risk.



...Appalachians...

Ahead of the cold front moving over the eastern US and Appalachians,

a few hours of gusty winds are possible this afternoon. Pre-frontal

winds may increase to 15-20 mph with RH values falling to near 25%.

The highest confidence for more sustained elevated conditions

appears to be across parts of western NC/SC where winds and lower

humidity may better overlap with recent fire activity and drier

fuels given recent rainfall.
