Summer's Kicking In...
After five straight days of clouds and rain Summer seems to be establishing itself now. Our eyes are on a potent shortwave diving into the Lakes right now this will continue to work East tomorrow and Wednesday before getting absorbed by a longer wave trough in Eastern Canada later in the week. Out ahead of the surface front associated with the shortwave humidity will be spiking and dewpoints will surge into the upper 60s tomorrow through early Wednesday. With the muggier air and the forcing from the front and cold pool of air linked to the shortwave, the threat for thunderstorms will be highest tomorrow night through early Wednesday afternoon before drier, more stable air starts returning.
Thursday and Friday the air will become more comfortable, at the same time, the longer wave trough will be spinning just north of the Maine / Canadian border. Normally this could mean pop-up showers or T-storms during afternoons but with the much drier air in place it looks like just some building cumulus for the end of the week with seasonal highs in the low 80s.
