Aggressive Cold Snaps into Mid Month Likely to Bring Some Snow

Long term models are coming together for some significant waves of cold air to surge out of the Arctic region, through Canada into the Midwest, Great Lakes and East over the next 10 days. A few periods of short moderation can also be expected between the cold blasts. A few of these cold air masses will be impressive even for early November standards.

A strong low pressure is slated to form along the axis of Polar-Arctic air as it plows south and southeast into the country. Intense energy aloft will also accompany the upper air dynamics as it makes headway into the country by Election Day.

Selected maps for the upcoming week, approximate timing and results:













The frigid air will arrive and be accompanied by waves of rain, cold and then likelihood of snow showers. There is even the possibility of a bit of measurable snow over Southeast Lower Michigan late in the week into the following week with this weeks system and a few clippers. Further out in la la land; look for some moderation toward Thanksgiving.

Will an infrequent type El Nino possible this winter be accompanied by non-typical El Nino weather? 

Watch for my innovative Winter Outlook developed the past few decades by Thanksgiving's Weekend. I know it's a bit later this year but latest El Nino and hemispheric pattern changes along with up to date latest guidance seem to be working well into my new researched analogues.
