The upcoming 7-10 days will feature two additional storms impact the area, including storm number 3 potentially providing wintry precipitation to northern regions as colder air gets back involved with the pattern.  No reasons for specifics now, but make a mental note that the pattern will be trending colder in the coming 7-10 day period.

A cold front will deliver light precipitation (rain and snow) to northern regions Monday into Tuesday.

Let’s keep a close eye on the Arctic Oscillation (AO) in the coming days.  Should it remain negative then the cold pattern may rumble well into April.  After a sharp decline mid month, members vary thereafter.  We’ll watch carefully.

Great Lakes ice coverage remains impressive, to say the least, for mid March at 69% total ice coverage- a byproduct of yet another frigid winter.

Speaking of the longer range, the latest JAMSTEC shows widespread cool and wet conditions over the Lower 48 for the March, April, and May period.
