   The severe weather threat for Severe Thunderstorm Watch 403

   SUMMARY...Instances of isolated large hail and locally damaging
   gusts remain possible across portions of Severe Thunderstorm Watch
   403 through around 01Z.

   DISCUSSION...Latest radar data from KJGX and KCLX depict widely
   scattered splitting/discrete thunderstorms with occasional supercell
   structures. This activity is being aided by a long/mostly straight
   hodograph (around 45 kt of 0-6 km shear), sampled by regional VWP.
   Antecedent heating/destabilization of a moist boundary layer (lower
   70s dewpoints) should support the maintenance of these storms
   through around 01Z -- despite the gradual onset of nocturnal
   stabilization. Given the aforementioned hodograph structure (and
   splitting storm mode), isolated large hail generally (1-1.5 inches)
   and locally damaging gusts (45-60 mph) are the main concerns.
   However, isolated hail up to 2 inches cannot be entirely ruled out
   with any longer-lived/organized supercell structures.
