We should consider ourselves lucky to live in such a great place with no threat of tropical disturbances, at least during the next couple weeks. T.S. Erin wreaked havoc on Houston and coastal Texas yesterday with torrential rainfall on the order of 6-10"+. Downtown Houston was absolutely at a standstill with many highways leading out of the city under several feet of water, prompting many to be rescued from their cars and trees. A few people lost their lives as well when the roofs they were under caved in under the stress of several feet of water that pooled up above them. There were several roof collapses.
Here in New England, we just had to deal with a couple thunderstorms last evening and overnight that is giving us a cloudy morning, with the threat of a few more showers later this afternoon probably in time for game 2 of the doubleheader against the Angels. Don't worry this will usher in crisp air for tomorrow and cool overnight lows starting tonight. Many suburbs away from Boston will fall to around 50 degrees tonight, a few upper 40's can't be ruled out tonight. Then for Sunday morning and Monday morning, we really get cool, even in the cities where they will fall in the lower to mid 50's.
The suburbs, on the other hand, will fall into the lower to mid 40's. I would not at all be surprised if places like Norwood and Bedford, MA fall perhaps to 39 degrees. Nashua, NH is another notorious coolspot during radiational cooling nights and temperatures around 40 are possible on both Sunday and Monday mornings. Up in northern New England, many cool spots in northern New Hampshire and northwest Maine will see temperatures in the mornings into the 30's. Mount Washington will likely see some SNOW on the day Saturday with very cold readings. Scattered frost is likely in some sheltered locations of northern New England.
The afternoons will be nice though with temperatures getting into the low to mid 70's in southern New England and mid and upper 60's in northern New England. It will be very pleasant and then by the end of next week after a few days of showers and possibly storms, the humidity and warmth will be reintroduced with highs getting back to 90? By Thursday.
