DAYS 1-5 (APRIL 15-19)
Temperature antics early this morning: upper 40s to middle 50s just after sunrise in most of the region while Logan sits at 67 with a west wind blowing “heat island” air across the harbor to the airport. This spot won’t rise too much today before it goes the other way, while most other areas do rise notably before the back-door front that chills the coast first eventually starts to penetrate inland somewhat, particularly from the MA South Shore northward to the NH Seacoast. The cooler side of the air battling air masses will reside over most of our region then through tomorrow, with a quick attempted warm-up that evening into Friday before another push from the north and east sends us to the cooler side once again. A series of disturbances from the northwest also brings us shower and thunderstorm chances at times later today as well as Thursday and Friday. Most times will be rain-free, but several opportunities for wet weather exist. Any rainfall is good for ongoing abnormally dry / drought conditions and also in keeping fire danger in check as we are in prime brush fire season now. One adjustment to the forecast is for Saturday which appears it may have more northeast to east wind instead of north to northwest. This leads me to believe that cloudiness will be more dominant than it would otherwise have been. After that, low pressure moving through the Great Lakes will shift our wind to southerly on Sunday, pulling warmer air back in, but its approaching cold front also brings a shower and thunderstorm threat before that day ends – more precise timing TBD.
TODAY: Variably cloudy. A chance of a pop up shower and slight chance of an inland thunderstorm. Highs 57-64 South Coast, 65-72 MA South Shore and Cape Ann to NH Seacoast, 73-80 elsewhere, but likely turning sharply cooler at least NH Seacoast and eastern MA during the day. Wind SW 5-15 MPH likely shifting to NE and E at least NH Seacoast and eastern MA during the day.
