Discussion\u2026<\/p>\n\n\n\n
The western US wildfire smoke plume in our sky peaks today, diminishes Thursday, and will be gone by the end of the week, due to a shift in the jet stream and a clean Canadian air mass arriving. Before that, we have 2 warmer days today and Thursday, although the smoke plume reflecting some of the solar radiation back into space will not allow temperatures to reach their potential highs had the sky but clear. Nevertheless, it will still be on the warm side and these are 2 good candidates for end-of-summer beach days. Although if you should travel to the coast today, I caution you that some lingering rough surf and resultant high rip current risk will exist due to offshore Hurricane Paulette. When a cold front crosses the region Thursday night, it will do so with cloudiness but no rain, it will usher in a cool air mass, and it will play a part in deflecting what could have been beneficial rain associated with the remains of Gulf of Mexico Hurricane Sally south of New England. In fact, the push of cool air will be strong enough that some interior lower elevations may see their first frost by Sunday morning, and Sunday’s high temperatures may struggle to reach 60 in some of the hilly terrain northwest of Boston – a pretty autumn-like feel to the final weekend of summer for sure.<\/p>\n\n\n\n

DAYS 6-10 (SEPTEMBER 21-25)<\/p>\n\n\n\n
One thing to watch early in the period is offshore tropical activity as it starts to transition into post-tropical low pressure. There may be a brief period of retrogression allowing a broad low pressure circulation to get a little closer to the coast – probably not close enough for rainfall as it stands now, but potentially close enough for some wind and ocean wave impact. By mid period we should be back into a warmer and more tranquil westerly air flow before a cold front approaches with a shower September 24 or 25.<\/p>\n\n\n\n
DAYS 11-15 (SEPTEMBER 26-30)<\/p>\n\n\n\n
Overall pattern remains dry, governed by high pressure. Temperatures variable, averaging near to slightly above normal.<\/p>\n","protected":false},"excerpt":{"rendered":"
