.SYNOPSIS...

Synoptic Analysis:
GOES-R moisture channel imagery along with global numerical model
depictions align well with an amplifying pattern over the country
with a potent upper low over Nevada and into Utah with a narrow
corridor of deepening ridging across much of Texas into eastern
Nebraska while closer to home the upper level troughing has become
enlarged with lower heights present over the central Gulf of
Mexico, associated with Subtropical Storm Alberto. Weaker mid
layer ridging exists near the Bahamas and extends further south
over the western Caribbean Sea.

Toward the surface, high pressure over the southwest Atlantic
continues to support a southeast to easterly flow across the
southeast while the National Hurricane Center analyzes the center
of Alberto over the southeast Gulf of Mexico. To the west, weak
high pressure was present across eastern Plains while multiple
centers of lower pressure were analyzed across the southern and
central Rockies.

Mesoscale Analysis:
GOES-R, NEXRAD and surface analysis data reveals the presence of
three low to mid level boundaries that are drifting northwest
across the forecast area this morning. The first boundary extended
from western Calhoun County and extended southwest into southern
Jefferson County and stretched southwest into northern Hale
County. Another boundary extended from northern Randolph County
southwest into central Dallas County. The third boundary was
located across northern Lee County and extended southwest through
central Montgomery County.

Sounding Discussion:
The 27/12Z BMX sounding contained a fairly uniform profile through
the vertical column that is resulting in a precipitable water
(PWAT) value of 1.77 inches. The absence of any notable dry layers
aloft along with low-level easterlies and gradual veering winds
higher aloft highlights the growing tropical influence the
atmosphere is experiencing with the approach of Alberto. Wind
speeds remain light from the surface aloft to around 350 mb with
values generally at or less than 10 knots. Further aloft winds do
increase to around 35 knots near 250 mb. The modified observed
sounding for afternoon forecast high temperatures yields a surface
based convective available potential energy value near 2300 J/kg
with a lifted index of -6.

tornado was the most destructive of record in the U.S. up until that time.
It pierced a five-eighths inch thick iron sheet with a two by four inch
pine plank. A brilliant display of lightning accompanied the storm. (David
