Discussion
The active weather pattern will bring us another storm system to deal with on Wednesday and this one may feature some accumulating snow at the onset. Low pressure will develop today over Texas and abundant moisture will feed into the system from the Gulf of Mexico. On Wednesday, this surface low pressure system will push northeastward with its large moisture field advancing to the Midwest and Mid-Atlantic. Another key player in the upcoming mid-week event will be strong high pressure that forms over southeastern Canada. This high will anchor an air mass that will be cold enough for widespread accumulating snow across the Midwest, interior Mid-Atlantic and much of the Northeast US. In the local area, there is likely to be some snow at the onset with a coating to an inch or two possible before any changeover to rain. To the north of here, 2-4 inches of snow can fall tomorrow in the Lehigh Valley and Pocono Mountains, but even those areas will see a changeover to rain.
