DISCUSSION
CLEAR SKIES AND DRY AIR ARE EXPECTED FRIDAY, WITH MODEST WEST-
SOUTHWESTERLY WINDS. THE OFFICIAL FORECAST BRINGS AFTERNOON RHS
DOWN TO 20-25%. HOWEVER, SOME MODEL GUIDANCE SUGGESTS A LOW-END
10-20% CHANCE FOR RHS TO DROP BELOW 20%, ESPECIALLY ATOP RIDGES
AND ANY SOUTHERN ASPECT SLOPES THAT ARE AROUND THE SPOT. WITH
SUCH DRY AIR FORECAST, MIXING HEIGHTS SHOULD HAVE NO PROBLEM
REACHING 4-5+ KFT. WITH WINDS BEING A BIT MODEST AT 8-12 MPH AND
GUSTS UP TO 15-20 MPH, VENTRATES WILL RESPOND WELL AT 60-80,000
KT-FT. THESE WINDS WILL DIMINISH AFTER SUNSET, AND COMBINED WITH
THE CLEAR SKIES, A NOCTURNAL INVERSION WILL BE QUICK TO DEVELOP
AFTER 6 PM, LOWERING MIXING HEIGHTS AND VENTRATES.
THE SAME SORT OF SETUP LOOKS TO OCCUR SATURDAY, WITH THE EXCEPTION
OF SLIGHTLY HIGHER RH VALUES (25-30%) DUE TO WEAK MOISTURE
ADVECTION WITH THE SOUTHWESTERLY WINDS.
