Warmup Awaits Midwest, East During Mid-January By Alex Sosnowski, Expert Senior Meteorologist January 12, 2015; 8:45 PM ET Despite some pockets of cold air in the Midwest and East during the first part of this week, the wheels of change are already in the works for a mild weather pattern for the middle of January. The storm departing the Northeast will briefly pull cold air into the Midwest and Eastern states into Wednesday. However, the jet stream is about to lock out the cold for the third and much of the fourth week of the month. The jet stream is a high-speed river of air high above the ground that guides storms and air masses along across the globe. According to Paul Pastelok, AccuWeather chief long-range meteorologist, During next week, the jet stream will set up in such a way as to keep arctic air bottled up across central and northern Canada and will allow mild Pacific air to flow from west to east across much of the United States. High temperatures may average 10 to perhaps 20 degrees Fahrenheit above normal in the northern tier states next week, compared to the 10 to 20 degree below normal temperatures during the first full week of January. In areas from Chicago to Boston and New York City, this will translate to multiple days with highs in the 40s F. In areas from Dallas to Atlanta, the upcoming pattern will bring highs in the 60s on at least several days. From Minneapolis to Buffalo, New York, highs will reach or exceed the freezing mark during a few days. Temperatures to Moderate This Week The weather pattern is in transition this week. Pockets of cold air will remain and can persist where there is snow on the ground into the middle of the week. Clear skies and light winds at night can lead to frigid conditions during the first half of the week over the Upper Midwest to the interior Northeast. accuweather/en/weather-news/warmup-mid-january-midwest-east/40522419
