Areas affected...portions of southeastern Texas into the lower
Mississippi River Valley
Concerning...Severe potential...Watch unlikely=20
Valid 042240Z - 050045Z
Probability of Watch Issuance...5 percent
SUMMARY...Scattered to numerous thunderstorms are expected to
continue across much of southeastern Texas and the lower Mississippi
River Valley over the next few hours. A strong wind gust or two is
possible.
DISCUSSION...Regional radar imagery depicts scattered to numerous
thunderstorms ongoing from southeastern Texas into northern/central
Louisiana and much of western Mississippi. Surface temperatures in
the upper-70s to lower-80s and dewpoints in the mid-60s to near 70 F
are supporting moderate buoyancy of 1000-1500 J/kg MLCAPE. Moderate mid/upper-level flow is supporting only 20-30 kts of effective bulk
shear, which is expected to limit storm organization through this
evening. Given only modest low-level lapse rates of 6.5-7.0 C/km,
the potential for strong wind gusts appears low, yet an isolated
wind gust or two in the 45-55 mph range is possible. The greatest
area of potential for a strong gust or two appears to be from
northeastern Louisiana into central Mississippi where a weak
mid-level disturbance is supporting locally greater effective shear
(up to 35 kts per latest mesoanalysis), which promotes marginal
storm organization. Given the limited nature of severe potential,
watch issuance is unlikely.
