Extremely Cold Weather Coming!

March 18, 2014; 9:53 AM ET


1. The air mass coming down this weekend into the Great Lakes and Northeast is impressive in regards to just how cold it will be outside. While I am done with winter, there's no stopping the train of cold air masses through early April, although there is a hint of warming coming. I do think Sunday through Wednesday, record high MINS could be challenged in many areas. That means that the lowest high temperature for the date could get broken. We may not break overnight low records because the wind stays up and keeps temps from falling off to record lows.

2. The El Nino is coming up and I noticed the 90-day average SOI value has fallen into the negative values on the Long Paddock site.

3. Snowfall map is below for the current storm. Next week, looks like we have a storm in the East again that could produce heavy snows. Not sure where just yet, but with the trough coming into the East, bets are that the places that got hit by snow will get hit again.
