DISCUSSION
A STRONG SAHARAN AIR LAYER (SAL) WILL CONTINUE TO MOVE WESTWARD
ACROSS THE REGION TODAY. MODERATE TO HIGH CONCENTRATIONS OF DUST
WILL PROMOTE HAZY SKIES, REDUCED VISIBILITY, AND POOR AIR QUALITY
WHILE LIMITING SHOWER ACTIVITY. ALONGSIDE THESE SAHARAN DUST
PARTICLES, DRIER AND STABLE CONDITIONS WILL PREVAIL AS A STRONG HIGH-
PRESSURE SYSTEM AND A MID-LEVEL RIDGE CONTINUE TO STRENGTHEN OVER
THE AREA. TODAY, RELATIVE HUMIDITY (RH) VALUES WILL REMAIN IN THE
MID 50S TO MID 60S, AND WINDS WILL BLOW MOSTLY FROM THE SOUTHEAST AT 15
TO 25 MPH, WITH GUSTS REACHING UP TO 30 TO 35 MPH, PARTICULARLY IN
THE AFTERNOON. RAINFALL COVERAGE TODAY WILL REMAIN MOSTLY NORTH OF
THE SITE. CRITICALLY DRY FUELS, HIGH KBDI VALUES, STRONG WINDS, AND
LOW MINIMUM RELATIVE HUMIDITY VALUES MAY PROMPT THE ISSUANCE OF A
FIRE DANGER STATEMENT LATER TODAY.
