No respite from winter chill for North America

The spring season officially commences on the 20^th of March in the Northern Hemisphere. Various weather activities around that time give us a feeling that winter is saying us good bye. However, this time round, the cold spell of winter does not seem to be in a hurry to leave, specially over the central and eastern states.

There are already signs of polar vortex and freezing temperatures coming to an end for many areas of the Midwest, but this year will definitely see a slow spring as cold wave will take few more weeks to subside and might stay till the third week of March. The Midwest and eastern states will see a chilly spring this year.

Various places including Minneapolis, Chicago and Detroit have been recording temperatures 6°C to 8°C below normal average. The coming weekend, arctic air is expected to shift to the Midwest and bring temperatures nearly 30°C below normal average. The maximum temperature at Minneapolis on Tuesday was only (-14°C) and the spell of cold air will cover cities like Green Bay, Fargo, Chicago and Traverse City. This cold air is expected to shift to southern and eastern states by next week.

The Polar jet stream along with the moist jet from the Pacific will bring some more winter storm in U.S to set an end to the winter season. Northern Rocky mountains, central plains, parts of Midwest and northeast will receive a long spell of snowfall before winter finally bids farewell.
