Sunny Saturday, With Some Changes To Sunday’s Forecast

I haven’t had to change a forecast too dramatically in a while, but Sunday is not looking quite a bit different than it did to me 36 hours ago (late Thursday). We have two reasons for the added clouds and small risk for showers and even a thunderstorm tomorrow. The first is a storm system off the coast of Florida which will move northward and quickly pass to our east on its way to Nova Scotia. The second weather system bringing the chance of showers is a cold front now in the Ohio valley pushing eastward.

It’s definitely going to be a lot warmer tomorrow with a taste of tropical humidity in the air. Highs will reach the 70s and, if we get enough sunshine, could nudge 80F. This isn’t going to last very long as drier and cooler air returns for Monday, but it will feel like summer tomorrow.

The biggest question I am wrestling with is just how much sunshine we see tomorrow during the middle part of the day. I think the morning may actually be quite gloomy with lots of clouds, some fog and showers scattered about on radar. Then, as the Atlantic moisture moves away and before the western moisture moves in, there will be a break. If you look at the map below I labeled the two areas of showers.


A slight deviation in area 1 to the west would bring a few more showers to the region; a jog to the east would mean we have more sunshine and likely hit 80F, even in Boston.


If you tailgate tomorrow morning for the Patriots game in Foxborough there could be a shower or thunderstorm. Kickoff should be dry and the showers to the west will likely hold off until the 4th quarter or even after the game. It will be in the 70s throughout the game with moderate humidity.

Dry weather returns for Monday with seasonably cool/mild readings. Assuming we don’t get much rain tomorrow, we are poised to have one of the driest Septembers in 6 decades. Water, water, water those plants.
