DISCUSSION
A WEAK COLD FRONT WILL APPROACH THE REGION FROM THE NORTH
AND WEST ON FRIDAY, WITH TEMPERATURES SURGING INTO THE 70S AHEAD OF THE
FRONT FRIDAY AFTERNOON. AHEAD OF THE FRONT, WINDS WILL BECOME GUSTY OUT
OF THE SOUTHWEST, WITH 20-30 MPH GUSTS EXPECTED. A HIGH OVERCAST WILL
LIMIT MIXING SOMEWHAT ON FRIDAY, THOUGH THE COMBINATION OF RELATIVELY
DEEP MIXING HEIGHTS AND STRONG SOUTHWEST TRANSPORT WINDS WILL SUPPORT
SMOKE DISPERSION VALUES IN THE EXCELLENT RANGE DURING THE AFTERNOON.
SINCE DEWPOINT VALUES WILL INCREASE IMMEDIATELY AHEAD OF THE FRONT,
RELATIVE HUMIDITY VALUES MAY REMAIN ELEVATED, WITH CURRENT MINIMUM RH
VALUES EXPECTED IN THE MID 40S FRIDAY AFTERNOON. AT THIS TIME, NO PRECIPITATION
IS EXPECTED WITH THE COLD FRONT PASSAGE, WHICH IS EXPECTED FRIDAY EVENING
INTO EARLY FRIDAY NIGHT.
