Latest Forecast
A trough, or dip in the Jet Stream, over the Eastern United States will promote dangerously cold conditions through today and tonight. With highs struggling to reach 20 degrees, accompanied by a northwesterly wind of 15-25 mph with gusts up to 40 mph will promote wind chill values as low as -15°F through Monday morning. Exposed skin could develop frostbite in just 10-20 minutes this weekend, and uninsulated and unprotected pipes may freeze or burst. Make sure you have a backup generator in the event of a power outage, as the internal temperature of your house could drop to unsafe levels in just 12-24 hours. Winds should subside Sunday night into Monday as a Canadian high pressure system settles over the Northeast United States. As a result, Monday will turn out partly sunny and not as cold with highs in the mid-to-upper 20s. As the Canadian high pressure system shifts offshore Monday night into Tuesday, winds will turn southerly and finally usher in a more seasonable airmass to the Lower Susquehanna Valley, with highs in the mid-to-upper 30s.
