DISCUSSION
A MOSTLY SUNNY, HOT, DRY, AND WINDY DAY IS EXPECTED TODAY.
TEMPERATURES NEAR THE FIRE ARE EXPECTED TO BE IN THE HIGH 90S
TO NEAR 100F THIS AFTERNOON, AND IT ISN'T OUT OF THE QUESTION FOR
TEMPERATURES TO EXCEED 100F IN THIS AREA. SOUTHWEST WINDS WILL
PICK UP THROUGH THIS MORNING, REACHING A PEAK THROUGH THE
AFTERNOON AND EVENING. SUSTAINED WINDS OF 10-15 MPH WITH GUSTS OF
25-30 MPH ARE FORECAST. THERE IS THE POTENTIAL FOR SOME GUSTS UP
TO 35 MPH LATE THIS AFTERNOON INTO THE EARLY EVENING.
ADDITIONALLY, IT MAY TAKE UNTIL MIDNIGHT TO SEE WINDS REALLY
START TO CALM DOWN THIS EVENING. ONCE THOSE WINDS PICK UP, MIXING
IS EXPECTED TO BE VERY GOOD TO EXCELLENT THROUGH MUCH OF THE DAY.
HUMIDITY WILL FALL INTO THE 20-25% RANGE THIS AFTERNOON, WITH
OVERNIGHT RH STRUGGLING TO GET BACK ABOVE 70%.
TUESDAY, A MOSTLY DRY COLD FRONT IS EXPECTED TO PUSH DOWN FROM
NORTH TO SOUTH THROUGH THE DAY. THIS WILL LEAD TO A WIND SWITCH
THROUGH THE DAY, AS WINDS TURN FROM SOUTHWEST TO NORTHWEST BY
TUESDAY AFTERNOON. WHILE WINDS ARE GENERALLY EXPECTED TO BE
LIGHTER TOMORROW AS COMPARED TO TODAY, SOME GUSTS OF 15-20 MPH ARE
NOT OUT OF THE QUESTION ALONG THE FRONT. THERE IS A VERY LOW
CHANCE FOR SHOWERS AND THUNDERSTORMS TO FORM ALONG THIS COLD FRONT
TUESDAY AFTERNOON AND EVENING. IF THEY DO FORM, THERE WOULD BE A
THREAT FOR DRY LIGHTNING AS VERY LITTLE RAINFALL WOULD BE
POSSIBLE. ANOTHER FAIRLY DRY DAY EXPECTED TUESDAY WITH AFTERNOON
RH AGAIN IN THE 20-25% RANGE AND HIGH TEMPERATURES REACHING INTO
THE 90S.
