   The severe weather threat for Tornado Watch 119 continues.

   SUMMARY...The severe weather threat continues through the afternoon
   across portions of the mid-Atlantic.

   DISCUSSION...Storms have developed along a cold front currently
   moving through far western Maryland, southern Pennsylvania, and
   northern Virginia. These storms have already produced near severe
   wind gusts of 44 kts in Hagerstown, MD. Temperatures have warmed
   into the low 70s and dewpoints have increased into the mid 60s F. At
   least partial clearing ahead of these storms should promote further
   destabilization with MLCAPE increasing to around 1000 J/kg in the
   next 1 to 2 hours. Therefore, damaging straight line winds appear
   likely in a swath across Maryland and southern Pennsylvania and
   eventually into New Jersey and Delaware with these storms along the
   cold front. 

   In addition, cells have developed ahead of the front across eastern
   Maryland, and southeast Pennslylvania. These storms will pose the
   best threat for a few tornadoes given the better storm mode
   (mini-supercell), and stronger low-level jet per DOX/DIX VWP. This
   low-level jet is expected to shift eastward by later this afternoon.
   This weakening, in addition to low-level veering, should lead to a
   somewhat reduced tornado threat when the line of storms along the
   cold front arrives. However, a QLCS tornado or two cannot be ruled
   out.
