DAYS 1-5 (SEPTEMBER 12-16)<\/p>\n\n\n\n
The frontal boundary that was draped over the region yesterday, and a player in what turned out to be two intense rain areas with major flash flooding (Leominster area, North Attleboro area), is washing out in place and what’s left of it will drift offshore today. A nearly indiscernible bubble of high pressure will be just enough to help clouds break for partial sun today, but any sun will help fuel a few pop up showers and a very low risk of a thunderstorm. The good news is today’s activity would not organize into quasi-stationary lines and dump a ton of rain, but would just be smaller single cells or small clusters that would pass by, albeit a bit slowly. We still have a very weak steering flow in this humid atmosphere. But things will change soon. The bad news is to get that change to take place, part of it involves another shower\/thunderstorm opportunity Wednesday, mainly afternoon and nighttime, as a cold front moves into the region from the west. This front isn’t an express train by any means, but it is going to moving along at least, just taking its time, so the shower threat persists into the early hours of Thursday before dry air arrives from west to east. This sets up a very nice Thursday afternoon through Friday with a well-deserved break in humid, wet weather. Friday is easily to be the weather pick of the week. Late Friday and Saturday our attention will be on Hurricane Lee as it makes its closest pass to our region. My expectation at the moment hasn’t changed much from my earlier ideas. Yes, we need to watch the storm. It’s going to send at least big waves and heavy surf into our coastal areas. It’ll probably invade eastern portions of the region, at least, with its cloud canopy. For the moment, I think the track of the accelerating \/ expanding \/ transitioning storm will be off shore enough that its rain shield will stay over water, making its closest pass during the first half of the day Saturday. If this idea is correct, we’d have a day with clouds overhead, but dry weather, and a gusty breeze on the back side of the passing storm, which will probably be a low end category 1 hurricane or strong tropical storm, in the process of transitioning from tropical to post-tropical. Lee will have been weakened by additional wind shear and a wake cool pool of water left behind by 2 recent hurricanes off the US East Coast.<\/p>\n\n\n\n

DAYS 6-10 (SEPTEMBER 17-21)<\/p>\n\n\n\n
A fair weather end to the weekend on September 17. Next trough brings a chance of wet weather early next week but is expected to be progressive, with a drying trend into and through the midweek period. Temperatures somewhat variable, but not that far from normal.<\/p>\n\n\n\n
DAYS 11-15 (SEPTEMBER 22-26)<\/p>\n\n\n\n
Looking for a generally zonal flow pattern, a little warmer than average but a cooler interlude or two. A little more confident we’ve lost the wet pattern at this point and are in a fairly quiet one.<\/p>\n","protected":false},"excerpt":{"rendered":"
