Big Storm and Trough Next weekend in the East?

 Temperatures are starting to really cool down across Canada as the nights are getting longer and the snow cover is starting to grow. These temperatures will across the Northern and Central Plains for the weekend with accumulating snow in Colorado, Nebraska, Kansas and South Dakota. This resevior of cold air will make its way south and east later next week.























One of my favorite teleconnection this time of the year is recurving typhoons in the western Pacific near Japan. The rule is if you see a Typhoon recurve to the east of Japan then expect a Trough to develop in the east coast of the United States within 6-10 days. Well there was a typhoon that curved just to the east of Japan late this week. So 6-10 days later would be Wednesday- Sunday of next week. Models are starting to advertise this trough and low pressure development.  Details are still vague but the potential in my eyes is there for a pretty decent fall storm system.  That will likely development in the Southern Plains along a front and then the area of low pressure will deepen tracking northeast into the Tennessee and Ohio Valley.  Causing lots of rainfall in the places that don't need it and the possibility of severe weather. Then as the trough deepens it will pull in some below normal temperatures changing rain to snow. As I see a possible snow in the upper Midwest and into the interior Northeast. Then with the trough digging into the east I can see the first snow flurries by the weekend as far south as Lexington, Kentucky and Washington D.C.
Stay tuned as just like was advertised a month ago that October was looking very active.
Have a great weekend everyone!! -Justin-
