Record Broken, Heat To Break
Posted by Chris Lambert
As of this writing (5PM) the highest temp we've reach all day at Logan Airport was 99 degrees. Just shy of the century mark, but hot enough to break a record. The old record of 98 was set back in 1982. Factor in the humidity and heat indices were consistently between 105-108 across the area.
So where do we go from here? Saturday will be another hot and humid day, but not a record breaker. Highs reach the lower to middle 90s before scattered storms move in to end the heat. There is enough instability and energy in the atmosphere to produce locally strong to severe storms, with the main threat locally damaging wind gusts. Frequent cloud to ground lightning and heavy rain will be more widespread than the damaging winds. The timing of the storms favors the most widespread activity between 4-8PM, but a few isolated storms could fire earlier in afternoon ahead of the main batch, especially north and west of Boston. Bottom line, keep an eye to the sky if you're heading to the beach. The lowest risk of storms will be across the Cape and Islands where much of the day is rain-free. A few evening storms are possible for the Cape however.
Sunday morning you'll be able to walk outside and take a deep breath as humidity starts to lower! By the afternoon, dew points fall into the mid 50s and highs max out only in the lower 80s. Quite a refreshing change of pace. We may start the morning in Buzzards Bay and the Cape with a few scattered showers Sunday, but much of the day will be dry.
Keep cool tomorrow!
