1147 AM CDT WED OCT 08 2025
VALID 081700Z - 091200Z
..UPPER MIDWEST
SURFACE HIGH PRESSURE MOVING INTO THE GREAT LAKES ALONG WITH LEE
TROUGH DEVELOPMENT ACROSS THE NORTHERN HIGH PLAINS WILL RESULT IN
INCREASINGLY SOUTHERLY FLOW ACROSS THE UPPER MIDWEST TODAY. A
RESIDUAL AND DRY, CONTINENTAL AIR MASS RESIDES OVER MUCH OF THE
UPPER MIDWEST, WITH CURRENT DEWPOINTS IN THE 20S ACROSS WESTERN
MN/EASTERN ND. INCREASING SOUTH WINDS TO AROUND 15 MPH BY THIS
AFTERNOON COMBINED WITH RELATIVE HUMIDITY AS LOW AS 15% IN SOME
LOCALES WILL YIELD ELEVATED FIRE WEATHER CONDITIONS ACROSS MUCH OF
THE RED RIVER VALLEY OF THE NORTH REGION TODAY AMID A DRY FUELSCAPE,
SUPPORTIVE OF WILDFIRE SPREAD. THE ELEVATED HIGHLIGHTS WERE SHIFTED
SLIGHTLY NORTHWEST TO ACCOUNT FOR LATEST OBSERVATION AND SHORT TERM
MODEL TRENDS.
..INTERMOUNTAIN WEST
INCREASING SOUTHWEST SURFACE WINDS OF 10-20 MPH ACROSS MUCH OF THE
SOUTHWEST, GREAT BASIN AND UPPER COLORADO RIVER BASIN ARE EXPECTED
TODAY AS A MID-LEVEL LOW NEARS THE PACIFIC NORTHWEST COAST. THE BEST
OVERLAP OF BREEZY SOUTHWEST WINDS ALONG WITH RELATIVE HUMIDITY
FALLING TO AROUND 15% WILL BE ACROSS THE DESERT SOUTHWEST, WESTERN
AZ AND SOUTHERN GREAT BASIN. HOWEVER, LIMITED FUEL DRYNESS WILL
SUBDUE A WIDESPREAD FIRE WEATHER THREAT, BUT LOCALIZED ELEVATED FIRE
WEATHER CONDITIONS ARE STILL POSSIBLE WHERE POCKETS OF DRIER FUELS
ALIGN.

..SYNOPSIS
UPPER RIDGING WILL OVERSPREAD THE CENTRAL U.S. AS MID-LEVEL TROUGHS
TRAVERSE THE EAST AND WEST COASTS TODAY. SURFACE HIGH PRESSURE WILL
PREVAIL OVER THE EASTERN U.S. AS SURFACE LEE TROUGHING BECOMES
ESTABLISHED OVER THE PLAINS STATES. ACROSS PORTIONS OF THE UPPER
MISSISSIPPI VALLEY, SOUTHERLY LOW-LEVEL FLOW WITH THE SURFACE
TROUGHING WILL BE DRY IN SOME LOCALES. ACROSS PORTIONS OF CENTRAL
INTO NORTHERN MINNESOTA, RH MAY DIP BELOW 30 PERCENT AMID 15 MPH
SUSTAINED SOUTHERLY SURFACE WINDS FOR SEVERAL HOURS. ELEVATED
HIGHLIGHTS HAVE BEEN ADDED WHERE THESE SURFACE CONDITIONS WILL
OVERLAP WITH DRY FUELS THAT SUPPORT WILDFIRE-SPREAD POTENTIAL.
ELSEWHERE ACROSS THE REMAINDER OF THE CONUS, GENERALLY QUIESCENT
FIRE WEATHER CONDITIONS ARE EXPECTED.
