Wednesday’s high temperature in Hyannis was an unseasonably warm (but certainly welcomed) 80F. Yesterday was actually the warmest day at that airport since September 26th, when the temperature also peaked at 80F. The warm temperatures, low humidity and sunny skies made for a nearly perfect weather day.
While it won’t be quite as toasty today, it’ll still be quite warm with temperatures peaking in the lower and middle 70s across most of the Cape (the average high for this time of year is right around 60F). A southwest wind off the water will keep temperatures a bit cooler in spots, mainly right along Nantucket Sound and Buzzards Bay as is typical for this time of year.
Overall dry weather and partly sunny conditions will prevail through most of the day, though there is a small chance for a shower or even a thunderstorm late in the day and into the evening hours. A disturbance sliding by the region will combine with the summer-like warmth over New England to initiate some shower and thunderstorm activity this afternoon and it’s not out of the question that one or two of these storms sneaks onto the Cape as it weakens later this afternoon.
That said, the best odds for seeing wet weather today are off-Cape where there will be more in the way of fuel to help develop clouds and storms over the second half of the day.
The HRRR model simulated radar tool does show some isolated to scattered shower and thunderstorm activity across the region today.
