The autumnal equinox -- the official end of summer, or better said, the official start of the fall season -- occurs at 9:49AM on Saturday. We don’t know about you, but we are more than ready for the coming weather changes!
Our forecast remains dry for the final official hours of summer; in fact, our current 7-day outlook is essentially rain-free for the entire period!
The winds are coming around, and we can expect flow off the Gulf with a slight increase in dewpoints over the next couple of days. We will warm things up a bit over the next two days as well, with highs on Friday and Saturday in the upper 80°s to around 90°. But the humidity levels will remain sufficiently low so as not to generate an “August” feel to the afternoons.
Our next front is still scheduled to arrive on Sunday morning and we still believe that it will be a “dry” front. Sunday’s front may be a few hours slower than what we thought yesterday, but we still expect the front to push out into the coastal waters by Sunday afternoon. Behind the front, we’ll enjoy another dose of cooler and less humid Canadian air. We keep highs in the mid to upper 80°s for Sunday through Thursday, with morning lows in the upper 50°s to mid 60°s.
T.S. Nadine is still hanging around just south of the Azores! The National Hurricane Center (NHC) suggests that Nadine will be losing her tropical characteristics in the next day or so, but the ‘post-tropical’ remains of the system could still be identifiable for another five days. Meanwhile, the broad low between Nadine and Bermuda that we mentioned on Wednesday has started coming together, and the NHC now thinks that tropical or sub-tropical is likely in the coming days. More problematic is the fact that the preliminary “spaghetti plots” have the system moving to the northwest over the next two to three days, and that could lead to a potential landfall threat for the Canadian Maritimes.
