DAYS 1-5 (AUGUST 19-23)<\/p>\n\n\n\n
We’re in a northwesterly air flow which is part of a weather pattern that deflects Hurricane Erin away from the Northeast later this week, but also brings us some unsettled and very cool weather for a part of this forecast period – but not all of it! No big changes to yesterday’s overall discussion though. High pressure overhead now provides a chilly start to today. We started to see a lot of high clouds yesterday streaming down from the Great Lakes and Canada in that northwesterly air flow and that continues today. Eventually a more solid mid level cloud deck will overtake the sky tonight into Wednesday, when we can see some occasional light rainfall as well. At the surface, an onshore flow can add some low level moisture and patches of drizzle. After today’s “fair weather cool”, Wednesday will have that more cool and raw feeling to it, a little out of character for late August weather. Hurricane Erin’s impact on our region will be limited to heavy surf and large swells, more on south-facing shores than east-facing ones, but still somewhat significant upon the latter. Weatherwise, we will only see a shield of high clouds in the southeastern sky, maybe up to overhead for a while, during Thursday. The storm itself will remain well offshore as it passes by. Heaviest surf \/ largest swells occur Wednesday through Friday (peak Thursday), and will settle down as we head into Saturday. Erin’s circulation will expand as it passes by, and its interaction with high pressure to the north will create a healthy northeasterly breeze here on Thursday, into Friday when it gradually loses some punch and shifts more to the north. By Saturday, high pressure is in control with tranquil and warmer weather.<\/p>\n\n\n\n

DAYS 6-10 (AUGUST 24-28)<\/p>\n\n\n\n
Warmer and a bit more humid August 24 ahead of an approaching cold front, which brings a chance of showers and thunderstorms later that day, and potential lingering showers and storms into a portion of August 25 as the front may be slow to pass through and exit offshore. Fair, cooler weather follows until the end of the period when there is another expected frontal boundary moving in with a shower and thunderstorm chance.<\/p>\n\n\n\n
DAYS 11-15 (AUGUST 29 \u2013 SEPTEMBER 2)<\/p>\n\n\n\n
Indications are for high pressure dominating into and potentially through the Labor Day Weekend (August 30 – September 1) with fair weather. May have to watch for a frontal passage and brief shower chance September 1 or 2, but timing and details of such features are not really certain this far in advance.<\/p>\n","protected":false},"excerpt":{"rendered":"
