Hello all & happy Thursday to you.  Not actually a bad day out there today. Pretty gorgeous when one considers the weather we’ve had.  Temperatures are approaching 60 across much of the area with some fair weather cumulus clouds bubbling up.

Sadly….enjoy it because the weather goes down hill tomorrow evening.  See that pink blob in Canada….that’s the tropospheric polar vortex and its headed our direction.

Friday

Overnight Thursday into pre-dawn Friday leftover showers move through the region bringing a sprinkle or two to many spots.

Locally during the day on Friday, the weather is quiet with temperatures reaching into the 50s.  A weak storm system moving through the Ohio River Valley approaches from the southwest late in the day.  This system is riding along the leading edge of the much colder air mass to our north and west.

Friday Night

As the weak system passes over the Cape Friday night it will bring showers and periods of precipitation to the region.  The airmass is so cold that snow may fall on the western edge of the precipitation shield and flakes may even make it to the coast early Saturday morning.

Any accumulations will be confined to the highest elevations.

Saturday

While snow in May is exceedingly rare many of us won’t see it. But that doesn’t mean the weather on Saturday doesn’t have the potential to be wild with the polar vortex over our heads.  In addition to a legit snow storm for northern New England (below), Saturday for the rest of us will be cool (40-45 F), windy (gusts 40-50) with occasional snow squalls.

Sunday

Things slowly return to normal on Sunday with temperatures approaching 50 and wind gusts dying down.  Still going to be brisk though.

The airmass above our heads is still going to be rather chilly through mid-week next week. Any hope of real warmth isn’t until next weekend.
