[UPDATED] You’ve heard it before: The convergence of thousands of meteorologists at AMS Annual Meetings brings unusual weather to the host city. Spring-like warmth this weekend in this year’s host city of Boston is continuing this trend.

As of 2 pm ET Sunday, the temperature at Logan International Airport has climbed to at least 73 degrees, breaking the monthly record high of 72 for the city set on January 26, 1950. It smashed the daily record high 61 first established in 1913.

On Saturday, southwest winds gusting to nearly 50 mph drove the day’s high to 70 degrees, topping the daily record set in 1975 by 8 degrees.

Sunday’s temperature could go even higher—nearby Norwood was 74 at 2 pm—before a a north-south cold front halfway across Massachusetts and Connecticut plows through Boston mid afternoon, bringing an end to the record-setting January thaw. Behind the front blustery northwest winds 40 mph or more will quickly tumble temperatures into the 40s by evening and closer to normal levels overnight and Monday.

We’ve written about the Annual Meeting weather coincidences previously on the AMS blog, dispelling the pervasive myth that our meteorological convergence brings bad and even dangerous weather to the Annual Meeting host city.
