Organized severe storms are not forecast on Tuesday.


A weak shortwave impulse, embedded within larger scale upper
troughing across much of the CONUS, will spread eastward across the
Southeast and into the Atlantic waters offshore from the Carolinas
on Tuesday. At the same time, another shortwave trough will dig
southward across the western U.S., resulting in weak lee
trough/surface low development over the southern High Plains. This
will keep persistent south/southwesterly low/midlevel flow over the
Gulf coast vicinity from TX through northern FL. Strong surface high
pressure over the northern Plains and Midwest will preclude the
northward advance of a stationary boundary just offshore from the
central Gulf coast into northern FL. Nevertheless, showers and
isolated elevated thunderstorms are possible in isentropic ascent
from the mouth of the MS River eastward along the central Gulf coast
and northern FL. Modest midlevel lapse rates and moderate shear will
reside over the region, perhaps resulting in a couple of stronger
storms. However, upper forcing will remain weak and instability
limited as richer moisture remains offshore over the Gulf. As such,
severe storms are not expected.
