DAYS 1-5 (SEPTEMBER 17-21)<\/p>\n\n\n\n
Discussion\u2026<\/p>\n\n\n\n
The western US wildfire smoke plume continues over our area through tonight, with one difference from the preceding couple of days in that there will be some actual clouds sharing the sky with it, first from the outer reaches of TD Sally which is now accelerating northeastward across the US Southeast and will pass offshore and south of New England during Friday. In addition, we’ll see an increase in mid level cloudiness from an approaching cold front from Canada by tonight. This front is likely to come through rain-free but will put an end to a brief warm up, bringing in a fresh Canadian air mass for Friday and the weekend. The dip in the jet stream helping to push this new air in will also serve to push the smoke plume out, and our sky, starting with cloudiness and still some lingering smoke aloft on Friday should end up turning much more blue before the end of that day. This will set up a bright weekend with crisp and cool air, so we will observe the last weekend of summer feeling very much like autumn. Meanwhile, Hurricane Teddy, the strongest of what is left active in the Atlantic, will be making its way northwestward in the general direction of Bermuda over the next few days. My early take on this system is that its center will pass east of the island, sparing them a hit as hard as Paulette gave them, however that’s no final call. Regardless of its track with respect to Bermuda, the jet stream may try to capture it as it loses tropical characteristics and pull it westward far enough to keep our air flow mainly from the north into the start of next week, prolonging our shot of cool air as we reach the final full day of summer on Monday.<\/p>\n\n\n\n

DAYS 6-10 (SEPTEMBER 22-26)<\/p>\n\n\n\n
High pressure centered to the northwest and offshore low pressure (Teddy) brings a cool northerly air flow to the region but with dry weather September 22, then high pressure sinks to the south and the low pulls away and we get a warmer westerly air flow with continued dry weather September 23. A cold front and a trough may pass by with some cloudiness and a risk of a brief shower during the September 24-25 period and should be replaced with another cool air mass. The only caveat this far in advance as we’ll need to watch Gulf of Mexico moisture for a potential trip into the eastern US near the end of this period, but odds favor a drier scenario.<\/p>\n\n\n\n
DAYS 11-15 (SEPTEMBER 27 – OCTOBER 1)<\/p>\n\n\n\n
This 11-15 day segment now includes the first of October, and a day that will be the first of 2 full moons in October 2020 – something we’ll talk about later along with some other significant celestial happenings for the month. As far as the weather pattern for the final days of September and to start October, still looking dry to me as high pressure remains the main player. This will continue to contribute to a worsening drought and higher fire danger.<\/p>\n","protected":false},"excerpt":{"rendered":"
