Forecast: Cloudy Workweek With Heaviest Rainfall Coming Wednesday

This article is more than 3 years old.

As the sun was setting behind high clouds Monday, I started thinking about how I wasn't going to see it again until maybe Thursday — and now, it could be as long as Saturday before we have a really nice day.

I'm not complaining, however. Springtime rain has been scarce for the past few years, and a wet spring is welcome — just not too wet. By the time this weather system is over, nearly 2 inches of rain will have fallen in many areas.

Today's rain is courtesy a slow-moving low-pressure system to our south. The radar loop below shows the rain moving in today and then becoming heavy before tapering to showers Thursday.

The reason we won't clear out quickly is because the storm is going to basically become stuck to our south and continue to spin clouds and some moisture into the area through Friday. While this is the case, the heaviest rain will be over by mid- to late morning Wednesday. After this time, showers will still fall.

As the storm spins south of New England, it will pivot showers through the area Wednesday afternoon and into the evening. On Thursday and Friday, clouds will dominate the sky, but I don't expect much rain.

Temperatures are very cool today, only reaching the upper 40s. Southerly winds will bring warmer and even slightly muggy air north on Wednesday. This air will be with us for the rest of the week.

The storm will also feature some wind and coastal flooding. Neither of these will be major or even moderate factors, but some minor flooding and coastal erosion are likely when the tides are high later today and again early Wednesday.

Thursday: Lots of clouds to start, then some breaks of sunshine well inland, but still the risk of a shower. Highs 71-74.

Friday: Partly sunny, pop-up storm possible. Highs in the mid-70s to approaching 80 inland.

Saturday: Mostly sunny. Highs in the 70s.
