DISCUSSION
A COLD FRONT IS EXPECTED TO BRING COOLER TEMPS AND
INCREASED LOW-LEVEL MOISTURE TO YOUR LOCATION FOR TODAY AND
SUNDAY. TODAY'S RH SHOULD BE IN THE MID TO UPPER TEENS WITH WINDS
SITTING JUST AT YOUR 20 FT THRESHOLDS (ABOUT 15-16 MPH). SUNDAY RH
IS EXPECTED TO INCREASE INTO THE 50-55% RANGE WITH THE BEST CHANCE
FOR ANY WETTING RAINS EXPECTED THIS DAY FOR THE REST OF THE
UPCOMING WEEK. BY MONDAY, THINGS WILL START TO WARM AND DRY AGAIN.
THIS MIGHT ACTUALLY BE THE BEST DAY TO MEET PRESCRIPTION AS RH IS
EXPECTED TO BE IN THE 25-30% RANGE WITH WINDS STAYING AT OR BELOW
16 MPH, THOUGH THE FORECAST CALLS FOR ABOUT .10" OF RAINFALL ON
SUNDAY, SO THAT COULD PLAY A FACTOR IN FUELS EARLIER IN THE DAY.
THINGS WILL DRY OUT QUICKLY AFTER THAT AND WINDS WILL INCREASE
BOTH TUESDAY AND WEDNESDAY THAT WILL BRING ELEVATED TO CRITICAL
FIRE WEATHER CONCERNS BACK TO THE AREA. AS OF NOW, IT LOOKS LIKE
ANOTHER COLD FRONT WILL PASS THROUGH SOMETIME WEDNESDAY THAT COULD
ALLOW FOR A FEW GOOD HOURS TO BURN ON THURSDAY AND FRIDAY
MORNINGS BEFORE RH DROPS BACK DOWN TO THE HIGH FIRE INTENSITY
RANGE. SMOKE DISPERSAL WILL BE THE LIMITING FACTOR (WINDS TOO IF
YOU PUSH IT INTO THE LATE MORNING) BUT IF YOU WANT TO TAKE
ADVANTAGE OF THE FEW HOURS IN THE MORNINGS JUST GIVE US A CALL
NEXT WEEK AND WE CAN CHAT ABOUT HOW WE CAN GET YOU IN
PRESCRIPTION.
