SIMILAR WEATHER WILL CONTINUE NEXT WEEK AND PARTICULARLY GUSTY
NORTH WINDS NEAR SHORE AROUND MIDWEEK.
DISCUSSION
HIGH PRESSURE WILL PEAK OVER THE WEEKEND WITHS
HIGHS IN THE UPPER 70S ACROSS THE INTERIOR. THERE REMAINS A SLIGHT
(15%) CHANCE OF SOME ISOLATED HIGHS EVEN OVER 80 ON SATURDAY
AFTERNOON. SOME GUSTY NORTH WINDS WILL REMAIN IN THE AFTERNOON,
BUT SLIGHT WEAKENING MAY ALLOW FOR COASTAL HIGHS IN THE 60S.
REGARDLESS CLEAR AND RELATIVELY DRY CONDITIONS WILL PERSIST.
A VERY SUBTLE SHORTWAVE PASSING THE EARLY NEXT WEEK COULD BRING VERY
LIGHT DRIZZLE WITHIN THE MARINE LAYER AROUND MONDAY, MOST LIKELY
JUST FOR DEL NORTE. OTHERWISE, THE WAVE WILL HELP PUSH STRONG NORTH
WIND S INTO THE COAST, WHERE NORTH GUSTS COULD AGAIN EXCEED 30 MPH
IN THE AFTERNOON. OVERALL CONDITIONS WILL REMAIN DRY WITH INTERIOR
HIGHS RIGHT AROUND 70. MOST MODELS HAVE NOW TRENDED TOWARDS HIGH
PRESSURE LASTING ALL NEXT WEEK WITH WITH LITTLE MORE THAN DRIZZLE
(20% CHANCE) POSSIBLE LATER IN THE WEEK ALONG THE FAR NORTH COAST.
HIGH PRESSURE WILL CONTINUE TO PROMOTE WARM INTERIOR TEMPERATURES,
THOUGH WEAKENING WIND THROUGH THE WEEK WILL MOST LIKELY ENCOURAGE A
STRONGER BUT SHALLOWER MARINE LAYER NEAR SHORE. /JHW
