It's certainly been a chilly spring across the Northeast, as evidenced by a fresh blanket of snow for many across the region earlier this week. But in Boston, this April could well wind up being the city's coldest April in over 50 years, if current trends hold. Through Tuesday, Boston's average monthly temperature of only 44.5 degrees ranked more than three degrees below the month-to-date average. That also matches 2003's 44.5-degree full-month average, and with more chilly weather expected over the final two days of April, it could well end up being the city's coldest April since 1965 (44.2 degree full month average temperature). Those readings are based on official National Weather Service observations at Boston's Logan Airport. This April, by the way, also included Boston's latest measurable snowfall in nearly 30 years back on April 18th. After a cool and cloudy Wednesday, more chilly weather is expected to round out the month in Beantown, with only an expected high of 50 degrees on April's final day. That'll perhaps knock back temperatures a tad, and make it the city's coldest April since the mid-60s. Several other areas are running well below-average so far this month, particularly in the mid-Atlantic and southern and central parts of New England.
