Well here we are at the end of the first weekend of August. Summer’s rolling along and whether you like heat or not, I bet you are wondering why we haven’t had any prolonged spells of heat. It’s just not the pattern this year. The various atmospheric indices have combined and conspired to produce a southward-displaced jet stream and frequent troughs dropping from Canada into the Upper Midwest, Great Lakes, or Northeast. This has kept heat in check. This same general pattern will continue into the middle of August. But pulling back a bit it’s time to look at the upcoming 7 days for the weather systems and resultant weather during this time.
We’ll continue to have that old frontal boundary sitting offshore early in the week, and a broad but weak trough of low pressure traversing the Northeast from west to east. It will take 4 days (through Thursday) to do this, so there will be daily opportunities for showers and thunderstorms, though it certainly will not rain much of the time, and some nice weather will also take place. By the time we get to Friday, the trough should be exiting to the east and a push of dry, cooler air will arrive. This sets up what looks at this time to be a great weekend as high pressure dominates. Again there is no major heat in sight.
Also, Tropical Storm Bertha will be taking a track between the US East Coast and Bermuda, passing well southeast of New England about midweek. The only impact will be some increased surf and rip current risks later in the week.
