    Today (Wednesday): Sunny. Warmer and a touch more humid. Highs mid to upper 80s. Overnight Wednesday Night: Clear. Muggy. Lows in the mid 60s. Thursday: Mostly Sunny. A stray shower or t’storm in western New England. Highs near 90. (Published Wednesday, Aug. 24, 2016)

    Under mostly sunny skies pour afternoon temperature nears 90° for the next few days.

    Then a front from Canada brings an isolated thunderstorm later Thursday and Friday, setting the stage for another beautiful weekend.

    Next week we have a very busy weather map, including the potential for two hurricanes from the Gulf of Mexico and the Atlantic Ocean. 

    Here are the details: 

    High pressure responsible for fair weather and chilly nights the last few days is now pushing off the Mid-Atlantic States to our south. Clockwise circulation around the high now brings in wind from the southwest. This is a warmer and more humid pattern. Highs today get close to 90°, then many us reach into the low 90s tomorrow and Friday. Breezes form the southwest become steady 10-20 mph, gusting to 30 mph with the front on Friday.

    This next weather front from Canada has much less energy than our previous Sunday night front that generated a tornado in Concord Massachusetts.

    This time we have a more subtle transition from near 90° and dew-points in the 60s, to lower 80s Friday, to high in the low 80s with dew-points in the 50s Saturday, even a bit cooler Sunday.

    So after a hit-or-miss storm Friday (no drought relief anticipated), sunshine returns for a comfortable sunny weekend. Wind this weekend is mostly light, but will turn onshore making the beaches just a tad chilly on Sunday.

    Yet another front from Canada is expected next Monday with the possibility of more a more significant period of rain and thunder Monday afternoon into early Tuesday.

    Will upper level wind delivering fresh does of air from Canada, we are somewhat protected from tropical trouble. 

    The tropics are busy: 

    By early next week we are likely monitoring two named tropical cyclones from the Gulf Of Mexico to the Atlantic Ocean.

    Gaston is expected to strengthen into a large and powerful hurricane curving out to sea well east of Bermuda.

    Gaston may generate a groundswell (long period ocean waves) of 10 feet or greater arriving in New England by Sunday and lasting several days next week.

    That surf may create hazardous conditions at the outer beaches of New England, meaning rip currents and high surf. Of course, surfer riders will relish this opportunity.

    Of much greater concern is the possibility of a another tropical cyclone developing east of Florida. By Saturday we may have the 'H' storm, Hermine may intensify from a tropical storm to a hurricane as it moves westward toward Florida this weekend. Not only do the residents of Florida have to keep a heads up, but sod residents along the Gulf of Mexico. The latest thinking for next Tuesday is for two named storms.

    Gaston curving out in the middle of the Atlantic. But Hermine may be a major threat for Louisiana and Texas. 

    Late next week we may get some beneficial rain from the remnant of Gaston merging with yet anther front from Canada nearing New England by next Friday or so. At that time, there may be another new tropical cyclone, perhaps Ian, the 'I' storm nearing the northern Caribbean.

    We could use the rain, but not the wind. Trees are in a weakened state in this drought. High winds would have a greater impact than in an otherwise wetter summer.
