Pennsylvania residents will be chilled to the bone as temperatures will drop to nearly 20-degrees! Scientists have been studying climate change, along with “polar vortexes” for several years. AccuWeather has predicted a harsh winter for the region, with freelance meteorologists projecting over 60″ of snow throughout the 2017-2018 winter. Tonight Temperatures will stay at 30-degrees of above, with partly cloudy skies. Wednesday Temperatures will drop to the low-20’s with partly cloudy skies. Thursday Temperatures will drop to the mid-20’s with partly cloudy skies. Friday A sunny day will be one of the final warm days, with a high of 46-degrees and a low of 36-degrees.

Following mild, wet weather to end this week, progressively colder air will unleash rounds of heavy lake-effect snow from the Upper Midwest to the interior Northeast for travel during the week of Thanksgiving. Travel delays related to wind and/or snow are likely in parts of the midwestern and eastern United States. “We expect two major pushes of cold air into the eastern half of U.S. during the week of Thanksgiving,” according to AccuWeather Long-Range Meteorologist Evan Duffey. The weather pattern is giving mixed signals as to whether a storm will bring rain and snow to the East during the transition to the cold weather. However, a certainty will be the consequences

A powerful coastal storm with strong winds and heavy rain will impact the east coast beginning later this weekend, potentially resulting in tree damage, power outages, and flooding. A wind event is possible Sunday or Monday according to the National Weather Service. This storm system will also receive an injection of moisture and energy from Tropical Depression eighteen in the western Caribbean. The National Weather Service in Boston has stated that this is an unusual and strong, potentially dangerous storm system for late October. In general, this east coast storm will be quick moving as it rushes northward this weekend into Monday. The storm timing is as follows: Saturday: Tropical moisture from

A storm with tropical origins will bring the potential for flooding and damaging winds along the East coast spanning Saturday into Monday. An area of showers and thunderstorms continued to gather along the coasts of Nicaragua and Honduras late this week. The storm will accelerate northward on a path that roughly parallels the southern Atlantic coast of the US on Sunday, prior to moving northward across New England Sunday night and Monday. As the storm continues to gather moisture and strength, locally severe thunderstorms may accompany torrential downpours in southeastern and central Florida and the northwestern Bahamas on Saturday and Saturday night. How strong the storm becomes will determine the severity

Some chilly winter weather is in store for the Northeast and mid-Atlantic, with January threatening to bring the coldest air of the season. For most of both regions, this will translate to an above-normal snow season. New York City and Boston, Massachusetts, may be the exceptions to this, with early predictions calling for 6 inches of snowfall or more above normal in both cities. Areas prone to lake-effect snow will also see high totals, including Cleveland, Ohio; Erie, Pennsylvania; and Buffalo, New York. The Northeast and mid-Atlantic aren’t the only ones who will feel the cold blast of this winter’s La Nina. Arctic blasts are set to freeze the northern Plains this winter
