DISCUSSION
EXPECT PERIODS OF CLOUDS AND SUNSHINE TODAY. THERE MAY BE SOME
SPRINKLES OR LIGHT RAIN SHOWERS PASSING OVER THE SITE THIS
AFTERNOON, BUT THE LOWER ATMOSPHERE IS EXPECTED TO BE WELL-MIXED
AND DRY, SO ANY RAIN WILL BE VERY QUICK AND LIGHT, IF IT HAPPENS
AT ALL. EXPECT MIN RH TO APPROACH 30 PERCENT OR SO. IT WOULDN'T BE
COMPLETELY SURPRISING TO SEE IT FALL INTO THE UPPER 20S, BUT
THERE'S ABOUT A 20 PERCENT CHANCE OF THAT HAPPENING. WINDS WILL BE
A BIT BREEZY TODAY AS WELL, AND GUSTS TO 25 MPH ARE EXPECTED. WITH
THE NORTHWEST FLOW GOING OVER THE NORTH SHORE TERRAIN, IT WOULDN'T
BE COMPLETELY SURPRISING TO SEE SOME BRIEFLY HIGHER GUSTS PERHAPS
APPROACHING 30 MPH THIS AFTERNOON.
HIGH PRESSURE WILL APPROACH GOING INTO SUNDAY, AND WINDS WILL
DECREASE IN SPEED A BIT BUT REMAIN OUT OF THE NORTHWEST TONIGHT
INTO SUNDAY. ANOTHER QUIET WEATHER DAY ON SUNDAY SLIGHTLY HIGHER
HUMIDITY AND LESSER WINDS COMPARED TO TODAY.
