Umbrellas were out in heavy rain on Commonwealth Avenue.

It’s finally dry. Wednesday marked the 10th day without any measurable precipitation in the Boston area, one of the longest stretches of the entire year without any rain or snow.

Don’t get used to it.

This weekend, a new storm system will move up the coastline and bring at least some wet weather to the region. The question is: Does this system mark the beginning of a new stormy pattern, or just an interruption in the current dry one?

The southern storm track may keep the heaviest rain and snow south of New England the next 10 days.

With all the shopping and traveling ahead, a return to stormy weather could be a damper for the holidays. It looks as though the storm track will continue to be active and threaten Southern New England through the weekend, although the worst of the weather may stay to our south, with areas around New York seeing over an inch of rainfall.

A weather phenomenon far across the world may save us from a direct hit from this weekend’s storm. There is an El Nino at work off the coast of Peru, which often suppresses the storm track through the middle of the Atlantic Seaboard and prevents storms from turning upwards toward our region. We can still get into a stormy pattern, however, and I actually see two or three chances of rain and snow between this weekend and Christmas.

El Nino conditions are present currently.

Early week storm

Late in the weekend, another storm will develop at sea and could provide some more light rain for Sunday night and Monday. This storm could also miss the area completely. It will remain chilly, but not cold enough for snow.

Heading to the holidays

A couple more storms will cross the country as travelers hit the roads and skies the week before Christmas. The map below shows the potential for a low pressure area on Christmas Eve. If you are hoping for a White Christmas, this may be your opportunity. However, as of now, the cold air could be lacking, which would mean a rainy Christmas instead of a snowy one.

Tropical Tidbits

Beyond Christmas, we may remain in a pattern where the cold Arctic air is locked up in Canada or spills into Europe and Asia. The lack of extended cold with any storms could actually keep the ground bare into 2019.
