   Concerning...Severe Thunderstorm Watch 86...

   Valid 080753Z - 080930Z

   The severe weather threat for Severe Thunderstorm Watch 86
   continues.

   SUMMARY...Overall severe threat across western MD and far northern
   VA appears to be diminishing. Although strong/gusty winds remain
   possible in the short term, additional downstream watch issuance
   appears unlikely.

   DISCUSSION...A line of storms is exiting the eastern portions of
   Severe Thunderstorm Watch 86 as of 0745Z. The airmass downstream of
   this ongoing convection is relatively cool/stable, with surface air
   temperatures generally in the low to mid 50s. Strong mid-level
   westerly flow is noted in recent VWPs from KLWX, but there will
   probably be a tendency for storms to remain slightly elevated above
   a near-surface stable layer as they move into central MD and
   northern VA. Although isolated strong/gusty downdraft winds cannot
   be ruled out, the overall severe potential appears increasingly
   marginal with eastward extent. Accordingly, additional downstream
   watch issuance appears unlikely at this time.
