WEATHER BLOG: Sunday

Rainfall amounts of 1.00 to 1.50 inches fell overnight (1.41" at Fort Ritchie, PA to 0.97" at the Science Center). We still have some lingering showers in the area, but they will come to an end by 10 a.m. this morning and clouds will then break for some peeks of sun in the afternoon. However, there could be a few passing showers around this afternoon, most numerous across southern Pennsylvania. Additional rainfall today may amount up to another 0.25 inches, especially to the north of the city. Becoming windy today as southeast wind this morning become southwest this afternoon with gusts to 35 mph possible.

It will turn much colder tonight. The wind will shift around to the west-northwest tonight with gusts around 30 mph still possible in the evening, but the wind will diminish quickly after midnight. Temperatures will plummet overnight and the sky will clear late. Despite plenty of sunshine on Monday, it will be windy and cold afternoon as temperatures recover only into the upper 30s.

On Tuesday, an Alberta Clipper type of winter storm will sweep across the Northeast bringing with it widespread snow showers across Pennsylvania and New York. The heaviest and most persistent areas of snow will be near the Great Lakes into the western Pennsylvania, but a few showers of rain or snow will make it over the mountains into eastern Maryland late in the day Tuesday. Temperatures will be above freezing Tuesday evening, but falling to a low of 20 degrees by Wednesday morning.
It will be cold but dry on Wednesday as morning clouds give way to some ineffective afternoon sunshine. It will remain dry but chilly Thursday and Friday. It will become cloudy on Saturday as a storm system develops in the southern Mississippi River Valley and pushes snow and ice northeastward into the Ohio Valley. This storm could bring us some wintry precipitation (sleet and freezing rain) or rain. Obviously, this far out there are a lot of uncertainties concerning the timing, track and intensity.
