Another mainly dry day on tap Sunday as high pressure continues

overnight. Minimum RH values fall to between 55 and 60 percent
for much of the area except for the immediate coast where values
will be elevated around 75-80 percent.
.Outlook...Monday through Thursday...
Strong high pressure for Monday brings blustery northwest winds,
dry weather and much cooler temperatures more typical of
mid-autumn for early next week.
