A developing storm center over the Mid-Atlantic – with sub-tropical origins – will ride northeastward today and tonight and intensify as it passes well southeast of us Wednesday morning.
While the brunt of this storm’s wind and rain will stay south of the Cape and Island, it will pass just close enough to us to give us a threat for some wet weather overnight tonight and into the first part of Wednesday morning. Rainfall totals don’t look overly impressive, with the best odds of seeing 1/2 to 1 inch of rain being out on Nantucket, closest to the storm.
In addition to the threat for some rain, a period of gusty northeast winds is anticipated overnight, with a few wind gusts to 30 to 40 mph possible at times – with slightly stronger winds possible out on Nantucket.
Drier air will take hold on the backside of the storm Wednesday afternoon, with developing sunshine anticipated.
