.DISCUSSION...
HIGH PRESSURE OVER THE REGION WILL BRING A STRONG VALLEY INVERSION
TO THE MONO BASIN THROUGH THURSDAY. THIS WILL RESULT IN POOR MIXING
WITH PERSISTENT LOW CLOUDS AND FREEZING FOG DURING THE NIGHTS AND
MORNINGS...AND ONLY PARTIAL AFTERNOON CLEARING. THE INVERSION WILL
ALSO KEEP THE VALLEY FLOOR SIGNIFICANTLY COLDER AND WETTER THAN THE
SURROUNDING HIGHER TERRAIN. ANY SMOKE WILL LIKELY END UP IN THE
VALLEY. STAGNANT WEATHER UNTIL SATURDAY WHEN A COLD FRONT WILL BRING
BREEZY CONDITIONS AND A SLIGHT CHANCE FOR SNOW.
