DISCUSSION
ANTICIPATE TEMPERATURES SIMILAR TO SATURDAY AND WEST TO WEST-
SOUTHWEST WINDS WITH GUSTS AROUND 15 MPH THROUGH 1200L. BETWEEN
1200L AND 1300L, WINDS BEGIN TO INCREASE WITH GUSTS BETWEEN 35 AND
45 MPH BY 1400L. THERE IS HIGH CONFIDENCE THAT THESE GUSTY WINDS
PERSIST OVERNIGHT AND INTO MONDAY. MOSTLY CLOUDY SKIES ARE EXPECTED
MUCH OF THE MORNING WITH CLOUDS SCATTERING OUT BETWEEN 1100L AND
1300L. MINIMUM RELATIVE HUMIDITY VALUES ARE CURRENTLY FORECAST TO BE
IN THE MID 30S, HOWEVER, THESE VALUES COULD BE A BIT TOO HIGH GIVEN
HOW GUSTY THE WINDS WILL BE. FAIR RELATIVE HUMIDITY RECOVERY
OVERNIGHT. PRECIPITATION CHANCES TODAY ARE LESS THAN 5 PERCENT BUT
INCREASE TO AROUND 70% BETWEEN 0300L AND 0500L MONDAY AHEAD OF AN
APPROACHING COLD FRONT. MONDAY WILL BE COOLER, WITH LIGHT SNOW
CHANCES THROUGH THE DAY AND GUSTY 30 TO 35 MPH WEST TO NORTHWEST
