...Windy Conditions Today Then Turning Cold Tonight...

.An upper low will swing through the area today, allowing winds 
to pick up to around 20 to 30 mph with higher gusts. These winds 
will calm down quite substantially this evening and the colder 
airmass will begin to settle down into the area. This puts the 
northern half of the area generally at or below freezing. Further
south, temperatures will stay above freezing for most of the area
but will still be in the low to mid 30s. Dewpoints will remain 
above 30 in these areas so patchy frost is possible. There could 
be a few spots in the south that drop to 32 degrees but those will
be more isolated than across the north.
