A high pressure system offshore will bring another day of dry, seasonable weather. A strong cold front will enter the region Thursday, bringing widespread showers, and a string of cool days will follow, according to the National Weather Service.
“Warmer wind directions are bringing in milder temperatures today,” said Charlie Foley, weather service meteorologist. “There is also a lot of moisture in the west, so tomorrow will be mild and showery, but nothing that will make a big difference in our deficit of precipitation.”
Today will be mostly sunny, with a daytime high near 57. Breezy conditions are likely this afternoon, with a south wind likely bringing gusts up to 20 miles per hour. Clouds will develop overnight and temperatures will remain relatively warm, around 50.
Showers will begin early Thursday morning, and should last until about 3 p.m. Boston has a rain deficit of almost 3 inches for the last month, and Thursday’s showers will only shrink that disparity by a quarter-inch or so, Foley said. Since September, Boston has amassed a rain deficit of more than 5 inches.
“Since it is not growing season, the consequences for us not having much rain is not that great,” Foley said. “Right now it’s not a big concern, but it’s something that is being monitored.”
Temperatures will rise into the low 60s through the day, and a southwest wind could bring afternoon gusts as high as 39 miles per hour, according to the weather service. Skies will become cloudy through the day, but clear up overnight. Temperatures will drop into the mid-30s overnight.
The sun will return Friday, with daytime temperatures cresting at 50. A west wind will bring gusts up to 20 miles per hour, cooling temperatures slightly. Skies will remain clear overnight, and temperatures will fall into the low 30s, according to the weather service.
“It will get cooler on Friday, and temperatures will get into the upper 40s,” Foley said. “Saturday will be a repeat of Friday, and there is no big weather pattern change for the beginning of next week.”
Saturday and Sunday should both be mostly sunny, but a few sprinkles could pop up Sunday. Daytime temperatures over the weekend will hover in the low 50s. Sunday showers will be widely scattered, and much of the state will remain dry, including the Boston area.
