Weekend weather sunny, dry and warm despite severe southern storm

A dangerous storm moving through the Gulf of Mexico and toward the Florida coast will not have a direct immediate impact on New England weather, according to the National Weather Service.

A swirling mass of air over warm southern waters grew to tropical storm strength on Sunday, and though Tropical Storm Idalia is predicted to potentially reach hurricane force before it makes landfall in the U.S. on Tuesday, weather in and around Boston should be mild if a bit wet midweek.

“It’s looking like there is a nice strong high pressure building up in southern New England, that’s why we’re looking at such nice weather on Friday, Saturday and Sunday,” Alan Dunham, a meteorologist with the NWS told the Herald.

According to Dunham, rain midweek should taper off by the weekend, when the weather is expected to be comfortably warm and dry.

A slight breeze off the ocean will bring clouds Monday morning, Dunham said, but the day is expected to be mostly sunny with a high near 75 degrees. The NWS predicts patchy fog is possible Monday before 7 a.m. and 62 degree low temperatures.

That same breeze will carry in rain clouds on Tuesday, according to the meteorologist, but chances of precipitation stay at 30% through the day. Temperatures Tuesday should match Monday, Dunham said, and stay in the mid-70s.

Thunderstorms are possible overnight Tuesday, according to the NWS, when the chance of rain jumps to 60%. Lows should be in the mid-60s.

Wednesday there is a 30% chance of showers or thunderstorms, but the day should for the most part be sunny and warm, with a high temperature nearer to 80 degrees.

Clouds are cleared by that southern New England high pressure system overnight Wednesday, Dunham said, when the weather becomes clear but with a stronger, up to 15 mph wind. Temperatures overnight could fall into the upper 50s, according to the weather service.

Weather on Thursday should be sunny with temperatures topping out in the mid-70s under an about 10 mph wind. Temperatures could be in the upper-50’s again overnight.

“It’s shaping up” to be a good weekend, Dunham said, and on Friday he expects mostly sunny weather to take over for the next three days.

Daytime temperatures Friday and over the weekend should hover in the mid-to-upper 70s and the lows stay above 60 overnight. Winds from the southeast are not expected to top 11 mph, according to the NWS.
