DISCUSSION
PERIODS OF HIGH CLOUDS WILL PASS OVER THE SITE THROUGH THE DAY
WHILE TEMPERATURES WARM TO AROUND 80 DEGREES. SOUTH-SOUTHWESTERLY
WINDS WILL BE USHERING IN LOW-LEVEL MOISTURE, KEEPING RH FROM
DROPPING AS LOW AS IT DID YESTERDAY. HOWEVER, THE WARM
TEMPERATURES WILL STILL ALLOW FOR RH TO DIP TO AROUND 35% EARLY
THIS AFTERNOON BEFORE GRADUALLY INCREASING. THERE IS A LOW CHANCE
THAT CLOUD COVER MAY BE MORE DENSE THAN CURRENTLY ANTICIPATED. IF
THIS OCCURS, THE MIXING HEIGHT WILL STRUGGLE TO REACH 4KFT. AGAIN,
THERE IS ONLY A LOW CHANCE OF THIS OCCURRING.
WINDS REMAIN SOUTHERLY TONIGHT AS SKIES BECOME MOSTLY CLEAR.
TEMPERATURES WILL BE WARM TONIGHT, WITH LOWS IN THE MID 60S
EXPECTED. THIS WARMTH WILL ONLY ALLOW FOR RH TO INCREASE TO AROUND
75%.
WINDS PICK UP OUT THE SOUTHWEST TOMORROW MORNING AHEAD OF A COLD
FRONT THAT WILL DROP THROUGH THE REGION LATE IN THE DAY. BECAUSE
OF THIS FRONT, CLOUDS WILL INCREASE DURING THE AFTERNOON. THE
FRONT DOESN'T MOVE THROUGH UNTIL THE EVENING, WITH WINDS BECOMING
VARIABLE AROUND 9PM BEFORE SETTLING OUT OF THE NORTH AND GUSTING.
A SOAKING RAIN IS THE EXPECTED (90% CHANCE) LATE THURSDAY NIGHT.
