Upper level low pressure will drop into the Great Lakes and spin around for a few days before lifting out into Canada late in the weekend. High pressure will hold strong in the western Atlantic. A cold front will settle across southern New England Friday then try to come back as a warm front Saturday, with a final front arriving from the west Saturday night into Sunday. The movement of this final front will determine Sunday’s weather, but suffice it to say that the next 3 days will feature unsettled weather with episodes of showers and thunderstorms and tropical humidity. The question is how much dry air from the west arrives during Sunday.
Perseid Meteor Shower: Meteors are visible, weather-permitting, during the overnight hours this weekend, with Saturday night being the peak and Sunday night a close second. The problem may be cloud cover. If we get lucky, some clear sky areas will work in at just the right time, so that some of the meteors will be visible. The best time to view, if the sky cooperates, will be between midnight and dawn Saturday night/Sunday morning and again Sunday night/Monday morning. Let’s hope for a few breaks.
