Discussion\u2026<\/p>\n\n\n\n
On yesterday’s discussion I mentioned that we’d see more cloudiness, starting with a shield of high cloudiness from the remains of Hurricane Sally. That indeed came along and combined with the smoke to limit the sunshine, which did not disappear as dramatically as it had in the smoke-only sky of the previous 2 days. The cloudiness thickened up overnight across southern areas, enough to produce a little bit of light, non-beneficial rainfall across the Cape Cod region first thing this morning. But in “blink-and-you’ll-miss-it” fashion, it will be gone soon, like it never even happened. Meanwhile, I spoke of a deck of cloudiness at mid levels heading toward the region in association with a cold front coming from Canada, and that deck of clouds is crossing the region now and will take all morning to do so. It even has retained enough moisture for a few sprinkles of rain, which may or may not be reaching the ground, parts of south central NH – another exceedingly non-beneficial “rain event” as our drought continues to worsen. What will change is the 2 warmer days we had will be a memory, as we head into a period of below normal temperatures today into early next week. I must also mention Hurricane Teddy, the second major hurricane of the season-to-date. This hurricane, while threatening Bermuda, will probably end up having less impact on the island than Paulette did, as it is likely to track just far enough east to keep the island out of the worst of it. For New England, it will produce another period of large ocean swells and rough surf, as is typical for a hurricane over the western Atlantic. This will likely impact our coastline at least through the weekend. So maybe it is a good thing that our final weekend of summer will feel more like early October, as going into the ocean water on a final beach weekend get-away will be very risky and is not recommended. If you chose to observe the rough surf, please do so safely. And in case somewhere you may have seen “alternate scenario” maps (I did), having the storm come much closer to New England, close enough impact for wind\/rain impact no, Teddy is not going to come close enough for direct impact on this area. It will serve to keep a northerly air flow going into early next week, prolonging our cool spell, along with causing the rough surf. The land mass in North America that should be on the look out for a possible direct impact is Nova Scotia. One final note, we will finally see the western US wildfire smoke plume pushed out of our area during the course of the day today as a Canadian air mass arrives, and it will stay away at least through early next week. But those fires will be burning for a while, so we probably have not seen the last of it…<\/p>\n\n\n\n

DAYS 6-10 (SEPTEMBER 23-27)<\/p>\n\n\n\n
A warmer westerly air flow takes over for the start of the period with dry weather September 23-24. A disturbance may bring a few showers September 25 and an air mass change to cooler again for the September 26-27 weekend. <\/p>\n\n\n\n
DAYS 11-15 (SEPTEMBER 28 \u2013 OCTOBER 2)<\/p>\n\n\n\n
Overall pattern looks fairly zonal with west to east air flow, a warm-up to end September and a cool-down to start October, based on current timing, and probably only a risk of brief wet weather with air mass change as the long term dry pattern continues.<\/p>\n","protected":false},"excerpt":{"rendered":"
