BOSTON — Compared to the past two days, a stark contrast in weather is expected the next couple of days. We won’t see much, if any, sunshine today or tomorrow, and there is rain back in the forecast. After a few morning showers the bulk of today is actually dry. However, there is the risk for some showers this afternoon, and if you see one it could contain some heavier rain.
The overnight period will be cloudy and damp, but generally rain free. Tomorrow a low-pressure area will move up along the coast and bring another period of showers or a steady rain to the area. There is still some discrepancy as to exactly how far north the rain shield will move. It appears right now the heaviest rain will be south of the Massachusetts Turnpike, but all areas will see at least some rain tomorrow.
Depending on the exact strength of the storm, rainfall could amount to more than an inch. I will be watching the afternoon models closely and be updating the forecast on Twitter.
The storm moves away on Friday and skies will partially clear. There is still a very small chance of a shower Friday. The weekend is looking fantastic with sunshine and warm temperatures. Highs both days over inland areas will reach 80 or higher, and even Cape Cod will be in the mid 70s much of Sunday — June weather at its finest.
There is still no sign of significant heat or humidity for southern New England as the jet stream remains in a position keeping the summer heat at bay for now.
Wednesday: Cooler with scattered showers and a thunderstorm possible. Much of the time will be rain free. Highs in the mid to upper 60s.
Wednesday night: Lots of clouds and still the risk of a few showers. Lows in the 50s.
Thursday: Periods of rain. Cool with highs in the upper 50s to mid 60s.
Friday: A blend of clouds and sunny periods. Risk of a shower or thunderstorm. Highs in the lower 70s.
Saturday: Mostly sunny with a high near 80.
Sunday: Mostly sunny with highs in the lower 80s (cooler on Cape Cod and the Islands).
