Warm, muggy weather expected to start off week

The start of the week won’t be a washout, though it will be warm and muggy, with afternoon showers and a chance of thunderstorms beginning today, the National Weather Service said.

Overnight showers gave way to mostly cloudy skies this morning. A warm front moving eastward will usher showers and thunderstorms into the Boston metro area after 2 p.m., meteorologist Bill Simpson said. It’ll be warm today, too, with highs expected to top 80 degrees in Boston.

There’s no telling exactly who will hear a rumble or two of thunder, Simpson said. The warm front makes the atmosphere consistently conducive for storm development across the state, though Simpson said any potential storms wouldn’t come close to those that ripped through the South and Midwest over the weekend. Rainfall totals won’t be significant, with a tenth to a quarter of an inch expected, Simpson said.

Things will temporarily cool and dry out Tuesday, with highs in Boston closer to the normal 67 degrees and patchy fog expected throughout the day.

Storms and warm temperatures will again return Wednesday, with scattered showers and thunderstorms possible in the afternoon as highs climb to the upper 70s, Simpson said.

It’ll be a muggy Thursday, too, with highs expected to reach 80 degrees and another round of afternoon showers and thunderstorms.

A cold front moving through Thursday night will help move the mercury back to normal, Simpson said, closing out the week with highs in the upper 60s and with scattered showers.
