Weather

By Roberto Rondanelli
STAFF METEOROLOGIST

Weather for the next couple of days will be dominated by the presence of a deep low pressure over the Canadian province of Quebec. The center of the low is forecast to be at 988 millibars, with isobars very close together (steep pressure gradient), consistent with strong sustained winds of about 30 to 35 mph for our region (about 50 to 60 km/h). Expect an abrupt transition of temperature as the cold front moves through Boston at the surface, in the early hours of the afternoon. The passage of the front should put an end to the warm spell after last weekend’s blizzard. The outlook for the next few days includes a very cold and sunny weekend due to the strong northerly flow associated with the anticyclonic (high pressure) circulation coming right behind the low.
