Mesoscale Discussion 0731

Areas affected...parts of sern MS...swrn AL...wrn FL PNHDL

Concerning...Severe potential...Watch possible 

Valid 070322Z - 070515Z

Probability of Watch Issuance...40 percent

SUMMARY...There still appears potential for convection to beco*e
better organized and intensify through Midnight-2 AM CDT,
acco*panied by an increase in potential for strong to severe surface
gusts.

DISCUSSION...Vigorous thunderstorm development is generally being
maintained within a broader area of convection, which continues to
spread eastward with large-forcing for ascent across the lower
Mississippi Valley.  One relatively broad cyclonic mesoscale
circulation remains evident near a clustering of persistent strong
convection, now near a remnant weak baroclinic zone east of Natchez
MS.  There still appears potential for this circulation to
strengthen along the thermal gradient, particularly as long as
south/southeasterly updraft inflow continues to emanate from a moist
low-level environment characterized by sizable CAPE.  This appears
to extend as far east as the Florida Panhandle.  03Z surface
observations suggest that convection may be contributing to a
notable surface pressure perturbation, with 3-4+ mb 2-hourly surface
pressure rises sampled at Greenwood, Jackson, Brookhaven County
Airport MS and Baton Rouge LA, and much weaker rises to weak falls
downstream.
