On this morning’s weather map, an east to west cold front is positioned from the southern New England Coast, the NY/PA line to the lower Great Lakes and Mid-west regions. On the western end of the front, a weak area of low pressure is evident.
Over the next 12 hours, this weak low pressure is forecast to traverse east to a location near Erie, PA by early evening. In doing so, the aforementioned front will stall and may even begin to retreat north as a warm front. Between the front moving back toward us and the approaching low, clouds will gain the upper hand this morning along with the threat for some light snow or flurries by afternoon. Accumulations, if any, will be negligible, say an inch or less.
Leftover snow or rain showers may fall early Saturday as temperatures rise into the 40s during the day as the warm front moves to the I-81 corridor by early evening. Even milder air will arrive Sunday as the warm front moves north and east of the region.
Thereafter, the front may briefly sag south later Sunday into Monday. This would result in the threat for a few showers as well as perhaps slightly cooler air Monday. Then, in response to a developing Mid-west storm, the front is forecast to lift back north as a warm front Tuesday. This would mean even warmer temperatures are possible Tuesday with highs reaching well into the 50s to near 60.
The threat for showers will likely increase Tuesday afternoon as a cold front works into the region. Behind the front, a return to (seasonably) colder air will return as well as the threat for snow showers.
