DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1144 AM CDT TUE JUN 10 2025
VALID 101700Z - 111200Z
..SOUTHWEST
ISOLATED TO SCATTERED THUNDERSTORMS ARE LIKELY OVER PARTS OF THE
SOUTHWEST IN AZ/NM THIS AFTERNOON WITH A SUBTLE UPPER TROUGH BENEATH
THE RIDGE. PWATS OF 0.75-1 INCHES, SLOW STORM SPEEDS AND SCATTERED
STORM COVERAGE WILL ENCOURAGE A WETTER STORM MODE DESPITE A
RELATIVELY DRY SUB-CLOUD LAYER. STILL, LIGHTING AND OCCASIONAL DRIER
STORMS, WITH LOW-END DRY THUNDER POTENTIAL, WILL REMAIN POSSIBLE
ALONG THE PERIPHERY ACROSS SOUTHWESTERN NM AND EASTERN AZ WHERE
FUELS ARE SLIGHTLY DRIER.
..ELSEWHERE
OTHERWISE, LOCALLY ELEVATED FIRE-WEATHER CONDITIONS ARE POSSIBLE IN
THE LEE OF THE SIERRA, BUT AREA FUELS HAVE BEEN TEMPERED BY RECENT
LIGHT PRECIPITATION. NO OTHER CHANGES WERE MADE, THE PRIOR FORECAST
REMAINS VALID WITH NO CHANGES.

..SYNOPSIS
A MID-LEVEL TROUGH WILL EJECT INTO THE ATLANTIC AS UPPER RIDGING
OVERSPREADS THE PLAINS AND A SECOND TROUGH IMPINGES ON THE PACIFIC
NORTHWEST TODAY. UPPER SUPPORT ASSOCIATED WITH THE WEST COAST TROUGH
WILL ENCOURAGE DRY DOWNSLOPE FLOW TO THE IMMEDIATE LEE OF THE
CASCADES. 15-20 MPH SUSTAINED WESTERLY SURFACE WINDS AMID 15-20
PERCENT RH BY AFTERNOON PEAK HEATING, ATOP DRY FUELS, WARRANTS THE
CONTINUATION OF ELEVATED HIGHLIGHTS.
THE PASSAGE OF THE MID-LEVEL TROUGH WILL ALSO ENCOURAGE THUNDERSTORM
DEVELOPMENT ACROSS SOUTHERN OREGON. A MIX OF WET AND DRY
THUNDERSTORMS ARE POSSIBLE, THOUGH THE LACK OF VERY DRY FUELS
PRECLUDES ISOLATED DRY THUNDERSTORM HIGHLIGHTS THIS OUTLOOK.
