Although LLJ is strongest on the Cape, they sometimes are a bit inverted with being near 50F water. It will probably be best just away from the S facing shores... just inland in SE MA especially.
Yeah in theory, what if you got exposed that day in the morning, tested in the aftn...but was negative? I feel like you may not have enough load to test positive yet?
I'm just giving them shit, they'll blow by me soon enough. It's still early all around, I think you'll be surprised how quickly it picks up where you are.
