DISCUSSION
A VERY DRY AIR MASS WILL BE IN PLACE TO BEGIN THE
PERIOD WEDNESDAY MORNING, BUT HUMIDITY VALUES WILL MAKE A SLOW
RECOVERY WEDNESDAY AS SOUTHERLY RETURN FLOW DEVELOPS AHEAD OF THE
NEXT COLD FRONT TO ARRIVE FRIDAY. HOWEVER, THE SPOT LOCATION STILL
STANDS A GOOD CHANCE OF SEEING CRITICALLY LOW RELATIVE HUMIDITY
LEVELS WEDNESDAY AFTERNOON AFTERNOON WHILE WINDS WILL INCREASE TO
BETWEEN 5 AND 10 MPH WITH GUSTS APPROACHING 15 MPH. HUMIDITY WILL
GRADUALLY INCREASE TOWARDS THURSDAY MORNING, WHEN A CLUSTER OF
SHOWERS AND THUNDERSTORMS IS EXPECTED TO MOVE THROUGH THE GENERAL
AREA. MEASURABLE RAIN CHANCES ARE AT AROUND 50 PERCENT RIGHT NOW,
WITH WETTING RAIN CHANCES AT BETWEEN 15 AND 20 PERCENT. REGARDLESS
OF IF RAIN REACHES THE AREA THURSDAY MORNING, THE DAY OVERALL

SOUTHWEST WINDS AHEAD OF FRIDAY'S COLD FRONT ARRIVAL.
