Frost advisory in effect overnight

Could be coldest night since April 15

Clear and cold tonight; frost in spots

Tonight: Clear and cold; frost in spots with a hard freeze possible in the northern tier. Low: 33

Tuesday: Mostly sunny. High: 65, Low: 40

There is a frost advisory in effect for most of the area from 2 a.m. until 9 a.m. Tuesday morning.

Overnight, we expect generally clear skies and temperatures dropping into the low to mid 30s; it could be the coldest temperature since April 15 when the low temperature was 33 degrees.

There will be frost in the normally colder spots and a hard freeze in some of the sheltered valley locations in the northern tier counties, especially north of the Lehigh Tunnel.

The rest of the week is looking relatively quiet. After a frosty start, Tuesday looks to be a beautiful autumn day with mostly sunny skies. Temperatures should reach into the mid 60s and lows in the lower 40s.

Clouds thicken later Tuesday and linger into Wednesday. The next chance for a shower or two may be Thursday night with the approach of our next cold front.

Tropical Storm Nicole will not be a threat to the U.S. mainland, but Nicole could intensify into a category 1 hurricane and possibly affect Bermuda sometime on Thursday.
