598 WWUS83 KLBF 260209 RFWLBF URGENT - FIRE WEATHER MESSAGE NATIONAL WEATHER SERVICE NORTH PLATTE NE 909 PM CDT SUN MAR 25 2012 ...CRITICAL FIRE BEHAVIOR POSSIBLE MONDAY... .CRITICAL FIRE BEHAVIOR IS EXPECTED MONDAY AFTERNOON ACROSS MUCH OF WESTERN NEBRASKA AS SURFACE LOW PRESSURE DEEPENS OVER THE WESTERN HIGH PLAINS. SOUTH WINDS WILL INCREASE THROUGHOUT THE DAY WITH GUST POTENTIAL OF GREATER THAN 50 MPH LATE TOMORROW AFTERNOON. COMBINED WITH THE POTENTIAL OF SUB 15 PERCENT RELATIVE HUMIDITY AND CURED FUELS THAT ARE PRIMED FOR CONSUMPTION...ANY FIRE START WILL HAVE THE POTENTIAL FOR EXTREME GROWTH AND EXHIBIT EXTREME BEHAVIOR. A DRY LINE WILL COMPLICATE THE SITUATION FURTHER...AS EXTREMELY DRY AIR AND A PRONOUNCED WIND SHIFT WILL ACCOMPANY THE DRY LINE PASSAGE. MODEL SOLUTIONS HAVE VARYING DEGREES OF THE EVENTUAL EASTWARD PROGRESSION OF THE DRY LINE. BUT CONFIDENCE IS HIGH THAT WESTERN PORTIONS OF FIRE ZONES 204 AND 210 WILL BE WEST OF THE BOUNDARY DURING PEAK HEATING...THUS IN PRIME LOCATION FOR RED FLAG CRITERIA. ACROSS THE CENTRAL SAND HILLS....THE DRY LINE PASSAGE IS EXPECTED DURING EARLY EVENING...THUS EXTREME FIRE POTENTIAL MAY BE LESS. THIS DRY LINE MAY ALSO SERVE AS A FOCUS FOR HIGH BASED THUNDERSTORM DEVELOPMENT ACROSS WESTERN NEBRASKA MONDAY AFTERNOON. IF STORMS WERE TO DEVELOP...STRONG ERRATIC GUSTY WINDS WOULD BE EXPECTED. ALL FIRE INTERESTS ACROSS WESTERN NEBRASKA INCLUDING THE CENTRAL SAND HILLS NEED TO CONTINUE TO MONITOR THE WEATHER SITUATION TOMORROW...AS THE EVENTUAL LOCATION OF THE DRY LINE WILL DICTATE WHERE RED FLAG CONDITIONS WILL BE OBSERVED. EASTWARD EXPANSION OF THE RED FLAG WARNING MAY BE NEEDED...BUT AGAIN THIS WILL DEPEND ON THE PROGRESSION OF THE DRY LINE. A FINAL NOTE...WIND SPEEDS WILL REMAIN ELEVATED WELL INTO THE EVENING WITH POOR RELATIVE HUMIDITY RECOVERY EXPECTED...WILL CARRY THE RFW WELL INTO THE EVENING...THEN MAY NEED ADDITIONAL RED FLAG HIGHLIGHTS ON TUESDAY AS CONDITIONS ARE EXPECTED TO REMAIN FAVORABLE FOR EXTREME FIRE GROWTH.

A RED FLAG WARNING MEANS THAT CRITICAL FIRE WEATHER CONDITIONS ARE EITHER OCCURRING NOW...OR WILL SHORTLY. A COMBINATION OF STRONG WINDS...LOW RELATIVE HUMIDITY...AND WARM TEMPERATURES WILL CREATE EXPLOSIVE FIRE GROWTH POTENTIAL. && $$ SJACOBS HTTP://WEATHER.GOV/LBF
