  1. A consensus of
       model forecasts suggests the greatest instability will develop from
       central North Carolina into southern and central Virginia, where
       MLCAPE values appear likely to reach the 2000 to 3000 J/kg range. In
       addition to moderate instability, NAM forecast soundings near
       Richmond, Virginia and Raleigh, North Carolina have steep mid-level
       lapse rates with relatively cool temperatures aloft. This, combined
       with 0-6 km shear in the 30 to 35 knot range will likely support
       supercell development. The potential for supercells will be greatest
       early in the afternoon, before storms merge into a line. Hailstones
       of greater than 2 inches in diameter will be possible with
       supercells that develop in areas that destabilize the most. The
       current thinking is that a relatively quick transition to a line
       will occur. This line is forecast to become organized, moving
       eastward across the Piedmont into the Raleigh/Durham and Richmond
       areas during the late afternoon. Wind-damage will be likely along
       the leading edge of the stronger parts of this line segment.

    With the majority of the rain behind us, time to look ahead to Monday to our next severe threat. Not a particularly high ceiling, but looks like it could be an enhanced type day if the timing is right

    ...DISCUSSION...
    ...Monday/Day 4...
    An upper-level low is forecast to move across the Great Lakes region
    on Monday, as an associated trough moves into the upper Ohio Valley
    and southern Appalachians. A moist airmass, with surface dewpoints
    in the lower 70s F, will likely be in place from the Carolinas
    north-northeastward into the Mid-Atlantic. Moderate instability is
    forecast to develop across much of this moist airmass by afternoon.
    Thunderstorms that form in the higher terrain will move
    east-northeastward into the Appalachian foothills during the
    afternoon. The instability combined with moderate deep-layer shear
    and steep low-level lapse rates will likely result in a some severe
    storms. Wind damage and hail are expected to be the primary threats.

    I will be ready!

    Why does it have to be cloudy?

    Holy shit, I've never seen the Bz at -30

    It is also because I am on a trip to El Salvador and this was the one I needed to see them in NC.

  5. This is one more from yesterday with the first wall cloud I saw near Apex at 3:47pm or so. You can make out the Shearon Harris cooling tower below it (it is actually probably quite a distance from the actual base of the cloud in this shot):
