This time of year, often New England and Miami feel quite different weather-wise.  This Saturday, not so much. 

As the Pats prepare to take on the Dolphins both Miami and Boston will near 90 with high humidity this afternoon.  The difference however, is that Miami’s heat and humid sticks around, ours won’t.

As a cold front plows into the hot and humid air this afternoon, thunderstorms break out across New England from northwest to southeast.  Outside 495, as early as 3-4pm, storms fire.  Inside 495, including the Boston area and North Shore, the start time for storms is likely in the 4-6pm time frame, and even later than that for Southeast Mass and the Cape and Islands.   There is a slight risk a few of these storms become severe with powerful wind gusts, but the more widespread aspect of these storms will be the locally heavy rain.  The atmosphere is loaded with water so any slow moving storm will be capable of producing standing water on the roads/parking lots/poor drainage areas, so localized flash flooding is possible as well.  We need the water on the lawn, we just don’t want too much to fast.

Storms taper off this evening, with the Cape and Islands the last to see them end.  It may take until midnight there.  Once the front passes, lower humidity starts filtering on in, and you certainly note the difference on Sunday with highs in the upper 70s and dew points falling toward 50 or lower! 

Monday looks great before clouds increase Monday night as a wave of low pressure approaches from the south.  We’ll watch to see how this develops, but right now it looks like the bulk of the rain stays out to sea Tuesday with just a few showers possible across Southeast Mass.

Enjoy the weekend and go Pats!
