The National Weather Service has issued a freeze watch for several counties in Southern and Central Pennsylvania, including Southern Centre, Southern Clinton, Southern Lycoming, Blair, Huntingdon, Union, Snyder, Montour, Northumberland, and Columbia. The watch is valid from 2 a.m. to 8 a.m. on Thursday, and sub-freezing temperatures as low as 30 degrees are possible. Freezing temperatures can kill crops and other sensitive vegetation, so protective measures should be taken now, such as bringing potted plants inside. Freeze watches are typically issued from May to October when low temperatures are expected to be between 29-32 degrees. If a freeze warning or watch is issued for your area, there is little you can do to protect plants other than moving them inside.
Freezing temperatures can damage or kill tender plants and vegetation, so it is important to take protective measures now. If you have potted plants, bring them inside. If you have plants that cannot be moved indoors, cover them with a tarp or blanket. You can also water your plants deeply before the freeze to help insulate them.
If you have any questions about the freeze watch, please contact your local National Weather Service office.
