Here is the latest snow forecast off the GFS for the Mid-Atlantic, Northeast snowfall through Wed. I am still going for a potential ALL snow event from around the Delaware-New Jersey line north but potentially SOUTH of Boston now due to a slightly further south track but I am not sure whether to now include DC within the ALL […]

Between Friday and today, the first of two significant late November arctic shots are bringing a distinctly December-like feel from the Dakotas all the way to Central Florida. The core of the cold was over the Upper Midwest Friday with highs only managing 10° in the Dakotas and by Saturday morning, as the cold air slide east as […]

  Well the arctic air has well and truely arrived in the Midwest with temperatures this afternoon a solid 30 below what they were yesterday. Minneapolis is stuck at 25 while Chicago rose to 31 and is now dropping, on their way to the teens tonight quite possibly. As the the trough slides east, biitter northwest winds blowing across […]

All week and even earlier I have been beating the drum of the dramatic flip from abnormally mild or warm to below normal cold with snow for the Windy City and other points. Check out the numbers for Friday! Also check out the temperatures for Minneapolis. Bare in mind that Rochester, MN recorded it’s latest 70 on […]

As this arctic air sweeps south and east bringing a sharp drop in temperatures following the abnormal mild of today and tomorrow, many ask, who where and how much snow will fall. Over the next 36 hours, as […]

  While arctic air will dive into the heart of the country late this week, unlike the last cold surge, this time around it’s going all the way to the Atlantic coast and that means the Big Cities. The last outbreak spared the big cities. Before the arctic air reaches the coast, later Friday and into Saturday will see a […]

Thought I would use Chicago as a good example of the wild temperature swing we are about to see across the heartland of the US over the next 72 hours. While a howlling Pacific flow warms the majority of the country with unseasonably mild air with many rising Wed and Thursday to between 15-25, locally […]

After what was a record dry and quiet spell, it seems the Pacific Northwest is catching up with the typical wet and stormy weather their so often use to during fall. In the past week, a sharp and large-scale pattern shift has meant to long awaited return of wet and stormy weather to Washington and Oregon extending south […]
