DISCUSSION
VERY WARM AND DRY CONDITIONS ARE EXPECTED FOR SUNDAY AS
HIGH PRESSURE CONTROLS THE REGION. LOOK FOR STEADY SW TO NE SURFACE
WINDS BETWEEN 5 AND 10 MPH THROUGH THE AFTENOON. A FEW GUSTS UP AROUND
15 MPH WILL BE POSSIBLE. IT DOES LOOK LIKE SOME VARIABLE UPPER CLOUDS
WILL BE AROUND THROUGHOUT THE AFTERNOON, AND COULD HURT MIXING A BIT
AT TIMES. THESE ARE EXPECTED TO BE SHORT-LIVED AND OVERALL BOUNDARY
LAYER MIXING AND DISPERSION LOOK STRONG THROUGH THE AFTERNOON. THERE
IS POTENTIAL FOR MINIMUM RELATIVE HUMIDITY VALUES TO DIP INTO THE 25
TO 30 PERCENT RANGE IF VARIABLE SKY COVER DOES NOT INTERFERE WITH
DEEPER MIXING, HOWEVER DIDN'T QUITE FORECAST THAT LOW AS SOME CLOUDS
ARE EXPECTED. WILL KEEP MINIMUM RH VALUES IN THE 30 TO 35 PERCENT RANGE
BUT DID ADJUST DOWNWARD A BIT FOR THE SOUTH ASPECT OF THE BURN.
