...widespread frost likely in many coastal areas late monday night
and tuesday morning...

.a strong cold moved through the region on sunday morning and is
producing much cooler and blustery conditions. there will be 
enough wind on sunday night to keep temperatures from falling 
below freezing in most areas. however, winds are expected to 
diminish by monday night and this will set the stage for 
widespread freezing temperatures across inland areas from late 
monday night into tuesday morning. in addition, frost is likely in
coastal areas as temperatures drop to near freezing.
