DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1157 AM CDT SUN APR 20 2025
VALID 201700Z - 211200Z
..17Z UPDATE
THE PRIOR FORECAST REMAINS ON TRACK WITH ONLY MINOR CHANGES TO THE
ONGOING FIRE-WEATHER RISK AREAS FOR THE LATEST GUIDANCE. ACROSS
SOUTHERN NEW ENGLAND, SEVERAL HOURS OF DRY AND BREEZY CONDITIONS ARE
POSSIBLE BEHIND AN OFFSHORE COLD FRONT. GUSTS OF 15-20 MPH MAY
OVERLAP WITH RH BELOW 20% THIS AFTERNOON. WHILE SOME WETTING RAIN
HAS TEMPERED FUELS ON A SCATTERED BASIS, ENOUGH DRY FUELS LIKELY
EXIST FOR SOME FIRE-WEATHER THREAT.
ACROSS PARTS OF THE DAKOTAS AND WESTERN MN, SEVERAL HOURS OF DRY
SOUTHERLY WINDS ARE LIKELY AHEAD OF A SURFACE TROUGH. GUSTS OF 20-30
MPH WITH RH BELOW 30% COULD SUPPORT SOME RISK FOR FIRE CONCERNS IN
DRY GRASSES AND FINE FUELS. HOWEVER, LARGER FUELS REMAIN LESS
RECEPTIVE AND SOME TRIMMING WAS MADE ON THE EASTERN EDGE WHERE
WETTING RAINFALL HAS OCCURRED IN THE LAST 72 HOURS.

..SYNOPSIS
A MID-LEVEL TROUGH AND CORRESPONDING SURFACE LOW WILL TRAVERSE THE
MIDWEST AS ANOTHER UPPER TROUGH EJECTS INTO THE ATLANTIC FROM THE
NORTHEAST TODAY, ENCOURAGING DEEP-LAYER OFFSHORE FLOW ALONG THE NEW
ENGLAND COASTLINE. WHILE THE OVERALL SYNOPTIC PATTERN DOES NOT FAVOR
WIDESPREAD, SIGNIFICANT WILDFIRE-SPREAD POTENTIAL ACROSS THE CONUS,
A FEW REGIONAL CONCERNS FOR ELEVATED CONDITIONS DO EXIST.
SOMEWHAT DRY SOUTHERLY RETURN FLOW OVER PORTIONS OF THE NORTHERN
PLAINS MAY PROMOTE 15-20 MPH SUSTAINED WINDS AMID 25-30 PERCENT RH
THIS AFTERNOON. SOME WILDFIRE-SPREAD POTENTIAL EXISTS WHEREVER DRY
FUEL BEDS ARE PRESENT. NEXT, DRY SOUTHEASTERLY FLOW WILL CONTINUE
ACROSS WESTERN PARTS OF THE FLORIDA PENINSULA, WITH ELEVATED
HIGHLIGHTS CONTINUED ACROSS THIS REGION GIVEN 15 MPH WIND SPEEDS
COINCIDING WITH 25-35 PERCENT RH ATOP DRY FUELS BY AFTERNOON.
LASTLY, 15-20 MPH NORTHWESTERLY SURFACE FLOW WILL OVERLAP WITH 25-40
PERCENT RH ACROSS PORTIONS OF NEW ENGLAND BY AFTERNOON PEAK HEATING.
GIVEN AN OVERALL LACK OF HEAVY RAINFALL IN THIS AREA IN THE PAST
WEEK, IT IS NOT OUT OF THE QUESTION FOR FINER FUELS TO RESPOND
ACCORDINGLY AND SUPPORT SOME POTENTIAL FOR WILDFIRE SPREAD.
