Day 3-8 Fire Weather Outlook  

NWS Storm Prediction Center Norman OK

0439 PM CDT Sun Apr 20 2025



Valid 221200Z - 281200Z



Across the CONUS, mid-level flow will become zonal and weaken

slightly over the next several days before a more amplified pattern

emerges mid to late week next week. Lee troughing and downslope

winds will increase from the Rockies to the Southwest. Dry

conditions and ridging aloft are also expected over the eastern US.

This will tend to support an increase in fire-weather concerns over

the extended forecast period.



...Southwest to the High Plains...

As flow aloft begins to increase with the more amplified flow

pattern, gusty winds and dry conditions are expected over much of

the western US. Lee troughing and gusty downslope winds are likely

over the Rockies and High Plains through early next week. Dry and

breezy conditions are expected over the Southwest and southern High

Plains, possibly extending into WY/CO. Given relatively dry fuels,

this will support elevated fire-weather concerns. Dry and breezy

conditions are also possible over the Great Basin, though fuels here

remain less receptive. A strong cold front will then move south

midweek, bringing cooler temperatures and limiting broader

fire-weather potential over the Plains.



There remains some uncertainty on the extent of fire-weather

conditions late next week into next weekend, as the cold front is

likely to usher in a cooler air mass over the southern High Plains

and parts of the Southwest. More sheltered areas in the southern

Great Basin and western NM may still have several days of dry and

breezy conditions as the main western US trough and flow aloft shift

eastward. However, confidence in the evolution of the upper-air

pattern remains limited, and no additional probabilities have been

added pending uncertainties on drying fuels.



...Southeast...

Subtropical ridging is excepted to gradually build through the

extended forecast period, keeping much of the Southeastern US warm

and relatively dry. Winds beneath the ridge should also remain

fairly light. Ongoing drought is likely to persist, potentially

supporting some fire-weather concerns through much of next week.

This is especially so over parts of FL where fuels are very dry and

easterly winds may reach 10-15 mph occasionally.
