'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.

Five-Day Forecast

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.

'Marchuary' – Colder Than January, February

February was record or near-record warm in a large swath of the southern and eastern U.S., so March has been quite a change in the Great Lakes and Northeast, especially.

Many Northeast cities are experiencing a colder average temperature this month through March 20 than the average temperatures they recorded in January and February.

Half of the village of Big Sur, on the coast of central California, has lost its only access to the north following the demolition of the flood-damaged Pfeiffer Canyon Bridge along State Route 1 (also Rt. 1 or SR 1) on March 19. Although Rt. 1 to the south of Big Sur has reopened to traffic (after mud and rock slides were cleared) it is a long 70-mile journey along the windy but spectacular highway to Cambria, the next town of any significance where supplies can be had. CalTrans (California Department of Transportation) estimates it will take 6-9 months to rebuild a new bridge over the canyon.

By now, many of you have heard or read about the arrest of Ahmed Mohamed, a 14-year-old high school student from Irving, Texas. Ahmed was arrested because school officials called the police after he showed one of his teachers his homemade clock. Mistaken for a bomb, Ahmed was taken into custody, interrogated, shamed, suspended (still on suspension today, Wednesday), and reprimanded. All of this after it has been found that the "device" he brought to school was indeed, a homemade clock.
