'Marchuary' Continues in Northeast as New Cold Blast Moves Into Region
Published: March 22, 2017
"Marchuary" continues in the Northeast this week despite the calendar now saying spring, as a new blast of cold air is surging into the region behind an arctic cold front. For many cities, the average temperature in March so far is lower than what was seen in January and February – hence the term, "Marchuary."

A southward dip in the jet stream, or upper-level trough of low pressure, is taking hold of the Northeast and Great Lakes region, allowing arctic air to spill south of the Canadian border.
Temperatures will be noticeably chillier Wednesday compared to Tuesday, with many areas seeing highs 20 degrees colder.
High temperatures will be 10 to 20 degrees below average, while lows will be up to 25 degrees colder than average from the Northeast into the Great Lakes.
Portions of the interior Northeast and northern New England will be stuck in the 20s for highs Wednesday and Thursday, and low temperatures will plunge into the single digits and teens. Wind chill values will be even colder as a stiff north to northwest breeze develops.

Forecast Morning Lows
Thursday morning will likely feature the coldest temperatures, and a few record lows may be challenged. This includes (current record in parentheses): Hartford, Connecticut (9 degrees), Binghamton, New York (9 degrees) and Scranton, Pennsylvania (9 degrees).
These cold temperatures will also allow the chance for some wintry precipitation. This includes a minor lake-effect snow threat in parts of western and central New York Wednesday morning, where most areas still have a deep snowpack from Winter Storm Stella. Accumulations are expected to be less than two inches in most spots, however.

The good news is this shot of cold air will be short-lived, and temperatures will return to average or above average Friday into Saturday. Parts of New England and New York may see cold air return Sunday, and there is the potential for some wintry weather, as well.
