Forecast: Much Colder — Though Mostly Dry — Weekend Ahead

This weekend, remember to set your clocks back one hour before going to bed Saturday night.

It's the return of Eastern Standard Time and those very early sunsets. If you are a morning person then you will be pleased to get back nearly an hour of daylight on the front end of the day.

Sunday morning, the sun rises at 6:24 a.m. and sets at 4:31 p.m. There will be enough light by just after 6 a.m to get in a run, but it's pretty dark by a few minutes after 5 p.m. For the next three months, we will see the shortest days of the year, with official daylight length at under 10 hours.

After some showers on Thursday, Friday brings a return to the sun. If there are clouds early, they will tend to depart leaving at least partial sunshine. Temperatures will be cooler today with highs in the lower 50s.

High pressure continues to rule Saturday and Sunday. There is a slight chance of a shower on Saturday, mostly north of Boston and across northern New England. I don't see these as a big issue and mainly something that won't happen, but I did want to mention them just in case.

It won't get very warm this weekend. After morning lows in the 30s, it only reaches around 50 in the afternoon. Remember, those high temperatures are for an hour of two of peak temperatures, most of the time it's in 40s.
