DISCUSSION
AFTER THE STORM YESTERDAY, CURRENT SATELLITE IMAGERY SHOWS CLEAR
SKIES AND MOSTLY LIGHT WINDS ACROSS VALLEYS AND MIDSLOPES OF AREA
MOUNTAINS THIS MORNING. THE CLEAR SKIES COMBINED WITH LIGHT WINDS
WILL LEAD TO SIGNIFICANT RADIATIONAL COOLING LEADING TO COLD
VALLEYS REACHING FREEZING TEMPERATURES THIS MORNING. CURRENTLY
LOOKING AT AN 85% CHANCE OR GREATER OF EXPERIENCING FREEZING
TEMPS THIS MORNING, AND A 50-60% OR GREATER TOMORROW MORNING.
GUSTY RIDGE WINDS PERSIST FROM THE EAST AND NORTHEAST THIS MORNING
ESPECIALLY OVER SIERRA RIDGES. HOWEVER, AS THE UPPER LEVEL RIDGE
STRENGTHENS TODAY THOSE WINDS WILL EVENTUALLY COME DOWN. ALSO
THOSE WINDS ARE INHIBITING THE CHANCES FOR FREEZING FOG OVER THE
MARTIS VALLEY THIS MORNING. ALTHOUGH ONCE THE WINDS DECREASE THE
CHANCES FOR FOG IN SIERRA VALLEYS POTENTIALLY RETURN BY SATURDAY
MORNING. OTHERWISE, EXPECT TEMPERATURES TO CONTINUE A WARMING
TREND THROUGH EARLY NEXT WEEK WITH AFTERNOON TEMPERATURES 10-20
DEGREES ABOVE NORMAL.
NEXT WEEK, A SERIES OF WEAK WAVES APPROACH THE GREAT BASIN. THIS
WILL LEAD TO TEMPERATURES PEAKING ON MONDAY AND TUESDAY, AS CLOUD
COVER INCREASES TOWARDS MID-WEEK. MODELS ARE VASTLY DIVERGING IN
THEIR SOLUTIONS STARTING ON WEDNESDAY RESULTING IN A LOT OF
UNCERTAINTY. FOR NOW, THE TREND THAT WE CAN SEE INDICATES COOLER
TEMPERATURES, BREEZY TO GUSTY WINDS, ESPECIALLY OVER AREA
MOUNTAINS, AND LOW CHANCES OF PRECIPITATION (20-30%).
