DISCUSSION...
WELL ABOVE NORMAL TEMPERATURES AND LOWER HUMIDITY VALUES WILL
CONTINUE THE NEXT COUPLE OF DAYS. WINDS WILL BE A BIT LIGHTER
TODAY AND A LITTLE MORE TERRAIN DRIVEN. THIS WILL LEAD TO LESSENING
VENTILATION. FAIR CATEGORY IS EXPECTED TO BE REACHED FOR 2 TO 3
HOURS TODAY...GENERALLY BETWEEN 1600 TO 1800. LOOK FOR ANOTHER
ROUND OF POOR TO MODERATE HUMIDITY RECOVERIES TONIGHT WITH
POOR VALUES ALONG THE MIDSLOPES. THE UPPER RIDGE WILL SOFTEN SOME ON
THURSDAY AND LEAD TO MUCH BETTER VENTILATION. WINDS WILL TURN MORE
WEST/SOUTHWEST ON THURSDAY. STRONG RADIATION INVERSION WHICH
DEVELOPED OVERNIGHT SHOULD BREAK BY THE NOON HOUR.
