A few showers will be possible this morning with the passage of 

the cold front. Nil rain chances are expected thereafter as drier 

air filters into the area. Expect freshening northwest to north 

breezes today with these breezes persisting through at least early

Wednesday morning before slackening. Sharply colder weather is 

also expected with temperatures falling to 5 to 10 degrees below 

normal and dew points slipping into the 40s, potentially even the 

30s. Min RH values are expected to be in the mid 40s percent today

and mid 30s percent Wednesday with max RH recovering to near 80 

percent at night.
