.DISCUSSION...
A VERY DRY AND INCREASINGLY UNSTABLE LOWER ATMOSPHERE TODAY THROUGH
SUNDAY WILL RESULT IN VERY WARM DAYS TODAY AND SUNDAY. AFTERNOON
RELATIVE HUMIDITIES WILL BE VERY LOW. A THERMAL TROUGH WILL MEANDER
OVER THE AREA THROUGH THE PERIOD LEADING TO SIGNIFICANT MIXING IN THE
AFTERNOONS. ALTHOUGH WINDS WILL BE LIGHT...THE DRY AIR COMBINED WITH
STRONG SURFACE WARMING AND GOOD MIXING WILL LEAD TO THE POTENTIAL OF
SOME GUSTINESS IN THE AFTERNOONS AND EARLY EVENINGS. IT SHOULD BE
NOTED THAT THE HAINES INDEX WILL BE MODERATE AT A 5 TODAY, DIMINISHING
TO A 4 ON SUNDAY DUE TO INCREASING MOISTURE ALOFT.
