A chilly, rainy Mother’s Day is in store for New Englanders
Bad news for outdoor Mother’s Day gatherings: After a week of clouds and cool temperatures, this weekend looks even worse. A storm will move up the coastline and bring a period of heavy rain and wind to southern New England late Saturday and continuing into Sunday.

A storm will move up the coastline Saturday bringing heavy rain and some wind.
Heading downhill
On Saturday, the clouds will thicken as rain arrives later in the day. You might see a few glimpses of sunshine early, but the trend is definitely for thickening clouds. If you have chores on your to-do list like mowing the lawn, get them done early. The chances of showers increase slowly past 2 p.m. By evening, rain is likely everywhere and it becomes steady and heavy overnight.

Temperatures continue below average on Saturday.
Make mom breakfast in bed
The nor’easter will still be underway on Sunday morning. This won’t be a great day to take Mom out for a walk, but a wonderful morning for serving breakfast in bed. Look for rain early, tapering to showers in the afternoon. Temperatures remain in the 40s much of the day, but will top out in the 50s if enough warmer air comes in from the south late. All in all, it will be a rather miserable Sunday.

Highs Sunday may reach the 50s late in the day, but the morning will be very chilly in the 40s.
Watch out for minor street and stream flooding
The big weather event this weekend is the rain storm. I am expecting up to 1-2 inches of rainfall from this weather system. If the storm tracks a bit farther south, we will see even less rain. This is possible. Our drought is officially over, but this rainfall will give us a nice cushion when it does turn drier next week. The heavy rain will be enough to cause some street, basement, and small stream flooding, mainly south of Boston. This doesn’t appear to be the type of storm that will cause the larger rivers to go into flood stage, and any flooding would be minor. I do recommend checking those sump pumps before the storm arrives.
