DISCUSSION
A VERY DRY AIR MASS OVER THE REGION CAUSED HUMIDITY
DOWN NEAR 11% YESTERDAY WITH A VERY POOR RECOVERY PEAKING NEAR 25%
EARLIER THIS MORNING. THE AREA WILL REMAIN UNDER THIS VERY DRY AIR
MASS MOST OF THE DAY UNTIL HIGHER DEW POINTS START TO MOVE INTO
THE AREA AFTER 1500 THIS AFTERNOON. AS A RESULT, EXPECT VERY LOW
HUMIDITY AGAIN TODAY, BUT A MUCH BETTER RECOVERY TONIGHT AS THE
DEW POINTS CONTINUE TO CLIMB.
WITH SUCH LOW HUMIDITY, TODAY'S WINDS PUT THE WEATHER CONDITIONS
IN RED FLAG WARNING TERRITORY, THE ONLY REASON WE HAVEN'T ISSUED A
RED FLAG WARNING IS BECAUSE WE HAVEN'T HEARD FROM PARTNERS IN THE
AREA YET THAT THE FUELS ARE READY DRY ENOUGH. TODAY IS A CRITICAL
FIRE WEATHER DAY.
