Forecast: After 2 Days Of Record Heat, A Cold Front Ushers In Rain

Wednesday was the last hot day for a while after another record-high temperature for Boston’s Logan Airport. This means an official September heat wave — the first since 1983 — is now in the books.

Boston also reached a high temperature of 93 degrees, which broke the old record of 91 set back in 1971. This is the second day in row of record heat.

Overnight, a cold front sliced through the region and is now slowing moving east. This front is going to act as the focal point for a period of showers most likely happening this evening through Friday morning.

About 1 to 2 inches of rain is expected in many areas, with some areas only seeing half an inch and others seeing up to 3 inches.

It won’t rain all the time, and the highest risk of rain is from about 2 p.m today until 8 a.m Friday.

Patriots Home Opener And Evening Commute

The New England Patriots season opener is tonight, and there will be showers and embedded thunderstorms in the area. If you are tailgating and then headed into the stadium, be dressed for muggy and possibly wet conditions. If there are downpours this evening, this could create problems for the evening commute as well as the drive to Foxborough.

Saturday is my pick for the weekend, with abundant sunshine, low humidity and pleasant September temperatures. On Sunday, another weather system brings more clouds and some showers. Temperatures on Sunday will be cooler than Wednesday by some 20 degrees.

Later next week, warm and increasingly humid weather returns. It’s highly unlikely we see a second heat wave in the month, but I would not be surprised if we do get several more beach days ahead.

Today: Warm and muggy with an increasing chance of showers during the afternoon. Some storms may contain heavy downpours. Highs near 80.

Tonight: Showers likely and possibly a thunderstorm. Turning cooler by morning. Lows in the lower 60s.

Friday: Morning showers and cooler. Highs in the lower 70s.

Saturday: Mostly sunny, with a high in the upper 70s.

Sunday: Clouds with scattered showers. Highs in the lower 70s.

Monday: Partly sunny, with a high in the mid 70s.
