Tropical Storm Isaias, which is curently located off of the coast of Georgia and northeast Florida will play a huge part in our weather for Tuesday afternoon and Tuesday night. The tropical storm is expected to start bringing some intermittent light to moderate rain into the region late tonight and Tuesday morning. The rain is expected to increase in intensity across Western Mass by late Tuesday afternoon with heavy rain expected for several hours on Tuesday night along and west of I-91. The track of Isaias will bring the center of the storm right across Western Mass. Since this is a lopsided storm, the heavy rain will fall to the west of the storm track and the strong winds will occur to the east of the storm track. Forecast Impacts: Heavy Rain: The heaviest rainfall amounts of up to 3 to 5 inches are expected west of I-91 and especially in the Berkshires during Tuesday afternoon and Tuesday night. Further east, the rainfall amounts are expected to be much lower with up to 1 to 2 inches possible across the I-91 corridor eastward to about the I-395/I-190 corridor. Along I-290 and I-495, less than 1 inch of rain is expected. This means that the highest flood threat will be in the Berkshires with flash flooding a possibility. Strong Winds: Right now, it looks like strong winds will be the much bigger issue with this storm rather than heavy rain. Wind gusts of up to 50 to 60 mph are expected across much of Western and Central Mass for several hours beginning Tuesday evening and continuing until just after midnight Tuesday night. These strong wind gusts will have the potential of bringing down trees and power lines leading to at least some scattered power outages. Isaias is expected to move out very quickly by late Tuesday night leaving us with at least a partly sunny and much calmer day on Wednesday. I am keeping extremely close watch on the progress and forecast of Isaias and will have additional updates for you as needed.

I continue to keep a very close eye on Hurricane Isaias as it will be moving along the East Coast of Florida on Sunday before heading northward and riding up the U.S. East Coast on Monday into Tuesday. I still think that Isaias will track over some part of Southern New England during Tuesday and Tuesday night. My thinking is for the center of Isaias to track across eastern Connecticut before moving across eastern Mass late Tuesday night. What does this mean for our weather? For Western & Central Mass, it means that rain is expected to overspread the region during Tuesday morning and become heavy at times during Tuesday afternoon and Tuesday night. Rain is expected to end late Tuesday night or Wednesday morning. At this time, I think that a couple of inches of rain looks likely across Western and Central Mass. As for wind, I think that since we will be on the western side of the storm, wind will not be too much of a problem. With that said, wind gusts of 25-35 mph are possible out of the north and northeast Tuesday afternoon and Tuesday night, especially in the Worcester Hills. For Coastal Southern New England, Rain and wind will gradually increase during the day on Tuesday and become a heavy wind-swept rain during Tuesday night. It currently appears that the center of Isaias will track right across southeastern Connecticut, central and northern Rhode Island and eastern Mass late Tuesday night. If this occurs, then wind gusts of up to 60 mph are possible across much of Rhode Island, eastern and southeastern Mass and the Cape. 1 to 3 inches of total rainfall is also forecast across eastern Mass and the Cape. Needless to say, I am watching Isaias extremely closely and will have additional updates for you over the next couple of days. Thank you for reading my latest forecast for Western and Central Mass.

I am keeping a very close eye on Tropical Storm Isaias, which is now approaching the Bahamas. Current forecast trends are for Isaias to not only strengthen into a hurricane over the next couple of days, but to also track northward along the East Coast of the United States this weekend into early next week. This means that Isaias may track very near, if not right over some part of Southern New England on Monday night and Tuesday. What does this mean for our weather? For Western & Central Mass, it means that a wind-swept heavy rain may overspread Western and especially Central Mass on Monday night and continue into Tuesday. How much rain falls will depend highly on the exact track of Isaias. Also, the strength of the wind will also heavily depend on the exact track of the storm. For Coastal Southern New England, A heavy wind-swept rain is expected beginning Monday night and continue into Tuesday. Based on the current trends in the weather forecast model guidance, it appears that the center of Isaias may track right across the Cape. If this occurs, then winds of up to 55 to 75 mph would be possible across the Cape with 35 to 55 mph winds possible along the South Coast of New England, as well as across coastal Eastern Mass. Needless to say, I am watching Isaias extremely closely and will have updates for you in the coming days. Thank you for reading my latest forecast for Western and Central Mass.
