The major storm that caused heavy rain in the I-95 corridor and heavy snow in parts of western and central New York, western Pennsylvania and West Virginia is slowly winding down. The upper-air pattern shows a strong ridge over the Rockies and a strong through in the East. By the weekend, a split flow pattern is predicted. One current will come in from the Pacific, then drop into a trough that moves across the Southwest and South Central states. Another current will move through western Canada, climb over a ridge in Manitoba, then head southeast to the northeastern part of the country. This will set up a huge temperature difference from north to south. This weekend's flow toward Virginia will start out over Arizona, while the flow coming to New York state starts over Hudson Bay! The video shows one of several outcomes.
Around accuweather.com headquarters, we saw snow, but the nearest significant accumulation was on the ridge tops. The camera peers out toward the ridge top and sees what was left of the snow on Tuesday morning.
...speculation about a snowstorm Monday or Tuesday, and one is still possible. However, timing and placement remain elusive. This map shows the GFS ensemble mean "solution" for Tuesday morning showing snow just off the New England coast. Watch this story evolve on accuweather.com all weekend.
As we look father out this month, it looks cold for the Great Lakes and Northeast (as well as deep into the South) in the middle of next week but milder the following week. This map, for next Wednesday, shows a cold flow from way north in Canada.
A few tornadoes can also occur, especially from Mississippi and Alabama to Kentucky. This map shows the areas of potential severe weather through tonight as forecast by the NWS Storm Prediction Center.
A less prominent but strengthening band of snow showers was moving southeast across Wisconsin. That feature is the one that would cause snow showers tomorrow morning in the Northeast Corridor.
On Friday, a northwesterly flow of cold air heads across the Great Lakes and into the the Northeast. By Sunday afternoon, the flow shifts dramatically to send milder air from the southern Plains toward the Northeast.
