DISCUSSION...TODAY AND TONIGHT
A COLD FRONT IS MOVING ACROSS THE AREA EARLY THIS MORNING,
USHERING IN MUCH STRONGER WINDS FOR THE DAY. WE'VE EXPANDED THE
RED FLAG WARNING TO THE NORTHERN PLAINS CONSIDERING THE LATEST
WIND AND RH FORECAST. FUELS ARE MARGINAL BUT LAND MANAGERS ALSO
REPORT THAT HIGH WINDS IN THOSE LOCALES MAY BE ENOUGH TO OVERCOME
THE RECENT MOISTURE AND MARGINAL NATURE OF THE CURRENT FUELS.
SINCE WINDS WILL GUST TO 40-50+ MPH, WE WENT AHEAD AND EXPANDED
THE RED FLAG. WE ALSO MOVED UP THE START TIME TO 9 AM CONSIDERING
THE WINDS AND THE MESSAGE OF JUST SIMPLY DON'T BURN TODAY, OR DO
ANY OUTDOOR ACTIVITY THAT MAY PRODUCE A SPARK. WE RECOGNIZE RH
VALUES ARE MARGINAL IN THE COOLER BUT STILL VERY DRY AIRMASS, BUT
ENOUGH THREAT OF RAPID SPREAD DUE TO HIGH WINDS TO WARRANT THE RED
FLAG WARNING. WINDS WILL DIMINISH QUICKLY BETWEEN 5 PM AND 7 PM.
MOUNTAIN AREAS WILL SEE SNOW SHOWERS EARLY THIS MORNING, ENDING BY
THE NOON HOUR.
LONG TERM DISCUSSION...TUESDAY THROUGH FRIDAY...DRY CONDITIONS
ALONG WITH LIGHTER WINDS WILL RETURN FOR TUESDAY AND WEDNESDAY
WITH SEASONAL TEMPERATURES. ANOTHER WEATHER SYSTEM WILL AFFECT THE
AREA ON THURSDAY BRINGING A CHANCE OF PRECIPITATION ALONG WITH
COOLER TEMPERATURES. DRY CONDITIONS WITH SEASONAL TEMPERATURES
WILL RETURN BY FRIDAY.
