Second Chance of Frost Later Tonight

Remaining Ad Time Ad - 00:00

The closed low pressure near the Michigan and Canadian border will continue to move over the Great Lakes through the day. We also had a weak cold front swing through the Tri-States earlier morning. This will create a cooler day, with highs only in the low to mid 50s. Winds are out of the northwest and will be just a little breezy. At least we'll enjoy another sunny day though.

Decent radiational cooling will take place Wednesday night as we'll have a mostly clear skies and light winds. With lows in the mid 30s, patchy frost will be possible again. Because of that, another frost advisory may be issued by the National Weather Service. If you haven't already, you'll want to cover your plants/flowers with bedsheets overnight. Or if you can, bring them inside if they're in pots.

The sunny forecast will continue into Thursday. The unseasonably cool temperatures will continue, with highs in the mid 50s.

Wednesday's Weather Word of The Day: Radiational Cooling

Radiational cooling conditions allow temperatures to very easily and quickly cool down. The easy way to think about it is like having a blank on your bed at night. With that blanket (or with the cloud cover) you stay warmer at night, as that blanket will hold a lot of the heat in. Remove the blanket (clouds) and you'll be getting cold, as the heat escapes your body.
