DISCUSSION
GOOD MORNING! LIGHT EAST TO NORTHEAST WINDS WILL INCREASE A BIT THROUGH THE
MORNING AND PEAK IN THE EARLY PART OF THE AFTERNOON. THE CENTER OF A SURFACE
HIGH PRESSURE WILL BE MIGRATING THIS WAY THROUGH THE DAY WHICH MEANS THE
WINDS WILL LIKELY BE DECREASING WITH TIME AS EVIDENT IN THE TRANSPORT WIND
FORECAST. THERE COULD BE A FEW GUSTS DURING THE AFTERNOON AS MIXING
OCCURS BUT EVEN THEN WINDS UP THROUGH 5000 FEET ARE FAIRLY LIGHT OVERALL...AND
ALL OUT OF THE EAST. RH VALUES WILL DROP FAIRLY QUICKLY IN THIS VERY DRY ATMOSPHERE
AND ESPECIALLY AS MIXING STARTS TO OCCUR. I HAVE ADJUSTED DEWPOINTS BELOW THE GUIDANCE
VALUES SO THE RH FORECAST REPRESENTS THE LOWER END OF THE GUIDANCE TO ACCOUNT FOR IT.
