Break from the extreme heat Wednesday; widespread showers and storms Wednesday PM

(Posted Tuesday 6/16 9pm)

The Shenandoah Valley Regional Airport (KSHD) made it to 94 today...this marks 6-straight days of 90+ heat which is the longest in the Shenandoah Valley since 11 in a row occurring June 28th -July 8th of 2012 (the derecho week).  Today's severe storm potential was a bit of a dud with most stronger activity dodging us to the south.  Convection was also limited by westerly, down-sloping winds...the all-too-common thunderstorm killer this time of year.
Shortwave riding along front Wednesday PM
Our 90+ streak should finally come to an end Wednesday with the front sagging just south of the area tonight before slowly lifting back north during the day tomorrow...Shenandoah Valley highs will top out in the low to mid 80s. We will stay dry until a shortwave swings through tomorrow evening bringing with it a large area of shower and thunderstorm activity.
18z NAM-Wednesday evening

Additional Notes

  • Enjoy the bit of a break from the heat because the southeast ridge will rear its ugly head again this weekend into the first part of next week (more 90s).
  • Tropical Storm Bill made landfall near in Matagorda, Texas around 12:35pm (11:35 CT) with max sustained winds of 60 mph
  • We may deal with some of this moisture this weekend (nothing major)
