A very mild Spring-like day is ahead… and milder weather headlines the upcoming week with a little hiccup thrown in the middle on Thursday. Tuesday turns out very mild under partly cloudy skies, with temperatures reaching the mid to upper 50s. A system will move in from the lower Ohio Valley region and will cross our area along the Mason-Dixon line and traverse across east central PA and then north central New Jersey on Wednesday, and we will be on the warm side of the system for much of the day and expecting rain as a result. There may be a squall line of thunderstorms in fact later in the day and evening as the associated frontal boundary passes through – and may produce some gusty winds. As the system passes to the east, winds will shift to the northwest and it will draw in colder air… possibly changing the rain to snow very briefly before it ends Wednesday overnight. Nothing in the way of accumulations is expected however. In the wake of the front, Thursday will be a very cold day with temperatures some 25 degrees colder than Wednesday for highs. Temperatures return to mild again once the southwesterly flow returns Friday and Saturday, and another system may affect the area late Sunday and early next week.
