DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0252 PM CDT SAT JUL 19 2025
VALID 201200Z - 211200Z
THE PRIMARY CHANGE WITH THIS FORECAST UPDATE WAS TO EXPAND THE
ELEVATED FIRE WEATHER AREA FARTHER EAST INTO PORTIONS OF
EASTERN/CENTRAL WYOMING, WHERE THE LATEST HIGH-RESOLUTION ENSEMBLE
GUIDANCE SUGGESTS SEVERAL HOURS OF DRY AND GUSTY WESTERLY WINDS
DURING THE AFTERNOON/EVENING. LOCALLY CRITICAL FIRE WEATHER
CONDITIONS ARE MOST LIKELY ACROSS THE SNAKE RIVER PLAIN IN IDAHO,
ALONG THE NEVADA/IDAHO BORDER, AND ACROSS THE WYOMING BASIN, WHERE
SUSTAINED SURFACE WINDS NEAR 25 MPH ARE POSSIBLE. CONTINUED DRY AND
BREEZY CONDITIONS ACROSS THE NORTHERN GREAT BASIN MAY ALSO LEAD TO
THE EMERGENCE OF LIGHTNING HOLDOVERS FROM SEVERAL RECENT DAYS OF
WET/DRY THUNDERSTORMS - ESPECIALLY ALONG THE PERIPHERY OF HEAVIER
THUNDERSTORM CORES.
LOCALLY ELEVATED FIRE WEATHER CONDITIONS ARE ALSO POSSIBLE FARTHER
SOUTH ACROSS PORTIONS OF CENTRAL/SOUTHERN NEVADA. AT THIS TIME, IT
APPEARS MID-LEVEL CLOUD COVER (CENTRAL NEVADA) AND RECENT HEAVIER
RAINFALL (SOUTHERN NEVADA) SHOULD LIMIT WIDESPREAD CONCERNS IN THESE
AREAS.
PLEASE SEE THE PREVIOUS DISCUSSION BELOW FOR MORE INFORMATION ON
TOMORROW'S FIRE WEATHER FORECAST.

/ISSUED 1240 AM CDT SAT JUL 19 2025/
..SYNOPSIS
THE UPPER-LEVEL PATTERN ON SUNDAY WILL BE SIMILAR TO SATURDAY.
HOWEVER, STRONGER MID-LEVEL FLOW MAY NUDGE SOUTHWARD AS THE UPPER
TROUGH AMPLIFIES THROUGH THE PERIOD IN THE NORTHWEST. SURFACE
TROUGHING WILL DEVELOP IN THE NORTHERN HIGH PLAINS.
..NORTHERN GREAT BASIN
ANOTHER DAY OF ELEVATED FIRE WEATHER CAN BE EXPECTED. WITH THE
STRONGER MID-LEVEL WINDS EXTENDING MORE TO THE SOUTH, GREATER
SPATIAL COVERAGE OF AT LEAST BRIEFLY 20+ MPH WINDS MAY OCCUR.
OVERALL, HOWEVER, 15-20 MPH WINDS WILL BE MOST COMMON. RH OF 10-20%
WILL BE POSSIBLE IN NEVADA WHILE IDAHO WILL MORE LIKELY SEE 15-20%
BY THE AFTERNOON. MODEL GUIDANCE DOES SHOW SOME POTENTIAL FOR HIGH
CLOUD COVER WHICH COULD ALSO LIMIT THE DURATION OF CRITICAL
CONDITIONS. ENSEMBLE GUIDANCE SHOWS LOW PROBABILITY OF SUSTAINED
CRITICAL CONDITIONS LIKELY ON ACCOUNT OF THOSE UNCERTAINTIES.
