DISCUSSION
BROAD HIGH PRESSURE WILL CONTINUE TO STRENGTHEN WHILE PUSHING

THURSDAY. BEHIND THIS SYSTEM, TEMPERATURES COOL WITH CONTINUED
ON AND OFF RAIN CHANCES INTO THE WEEKEND AS THE FRONT STALLS
NEARBY.
MINIMUM RELATIVE HUMIDITY VALUES WILL FALL INTO THE 30 TO 45 PERCENT
RANGE THIS AFTERNOON WITH SOUTH TO SOUTHWESTERLY WINDS GUSTING UP TO
15 MPH. EXPECT RECOVERIES BACK AROUND 70 TO 90 PERCENT MONDAY NIGHT
WITH 25 TO 35 PERCENT VALUES TUESDAY AFTERNOON AS THE RIDGE OF HIGH
PRESSURE STRENGTHENS FURTHER.
RAINFALL AMOUNTS THROUGH WEDNESDAY WILL RANGE BETWEEN A QUARTER TO A
HALF AN INCH. MOST OF THIS WILL OCCUR ON WEDNESDAY AS THE FRONT
