Here’s what to expect with this weekend’s weather and the approaching storm

The weather pattern has certainly changed this week and already eyes are focusing on the next storm that will likely hit New England on Sunday.  For Patriots fans, the next area of low pressure will impact the game, bringing at least a few showers and perhaps some heavy downpours on Sunday. For the rest of us, plan to finish your outdoor work during the first half of the weekend.

Friday is looking fantastic with plenty of sunshine and seasonably cool temperatures, with highs a few degrees on either side of 60 this afternoon. This is one of two really nice days we have before clouds and wet weather return Sunday.

Fast-moving jet stream

The jet stream is moving quite rapidly across the United States and will pick up a storm system over the southeast and bring it up through New England on Sunday. An earlier forecast called for the storm to reach the area Sunday night, but now because of the speed of the atmosphere, it looks like Sunday will go downhill much faster.  You should expect rain and wind to move in during the day.

How much rain and wind?

The biggest question I have for this upcoming storm system is how much wind and rain eastern Massachusetts will receive.

The strongest wind is forecast to stay over the ocean during Sunday night and early Monday. —Tropical Tidbits

The exact track of the system will put certain areas on the wetter side of the storm, and other areas on the windier side. This is similar to a tropical system.

Based on the latest computer guidance, the heaviest rain will stay west of the coastline and places like Cape Cod will receive the least. Areas out towards the Pioneer Valley will receive the most. A wobble of the storm as it pushes through the area means different rainfall amounts for different areas.

The threat of wind reaching damaging levels still exists, especially along the coastline. We’re more likely to see winds in the 30 to 45 mile per hour range along the coastline, especially on Cape Cod. I would use the term breezy conditions over the interior. This is good news, because with the leaves still on the trees, a lot of wind would cause more power outages and some damage.

Since the storm system is moving so fast, it’s also going to move out more quickly, so the Monday morning commute is less likely to be impacted by rainfall. There still might be an early morning shower, but the trend Monday is going to be for clearing skies. Seasonably cool temperatures and dry weather should last into the middle of next week.
