Yesterday at 21:04 the autumnal equinox marked the end of astronomical summer and the beginning of astronomical autumn. As if on cue, cool air rushed in and the feeling of autumn is sure to be in the air today. In fact, there’s more of a mid to late October feel in the air than late September. Highs today range in the mid to high 50’s and wind gusts up to 30 miles per hour. On shore waves are up to 5-10ft thanks to Fiona heading east tonight hitting Nova Scotia. The waves on our coast will be 6-12 feet tomorrow which also increases the risk of dangerous currents.
The cold follows yesterday’s cold front, which helped produce 0.75 to 1.50 inches across much of the area, with locally 2 inches and higher for parts of the southeastern Mass. It was certainly a beneficial rain event.
Tonight, as clear skies and a slacking wind win, temperatures will drop rapidly, back into the 30s to below 40s for many by tomorrow morning.
Recovery tomorrow is nice, with highs in the mid 60’s during the afternoon. On Sunday we will advance to almost 70 with increasing cloudiness. While a scattered shower can’t be ruled out late Sunday, there’s a better chance of a few isolated showers Sunday evening/Monday morning. Overall it’s going to be a nice weekend with a cool but cozy start Sunday for the Making Strides Walk in Boston and a nice afternoon for the Pats Game.
In the tropics, Fiona is just west of Bermuda this morning and will slam into Nova Scotia this evening into tomorrow, generating near 100 mph gusts there. Cape Brenton Island and Prince Edward Island are likely to have some of the strongest impacts.
Tropical Depression 9 also formed in the Caribbean this morning and is likely to become a hurricane early next week as it crosses Cuba and approaches Florida.
