Day 1 Convective Outlook

Valid 062000Z - 071200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM CENTRAL LA
INTO SOUTHWEST AL...
A few strong to severe storms are expected today over parts of
Louisiana, Mississippi, and Alabama. Damaging wind gusts will be
the primary hazard.
...Far Southeast TX into West-Central GA...
The cold front continues to push southeastward, with recent surface
analysis placing it from HOU northeastward to near BTR before
becoming more wavy due to augmentation by convective outflow across
MS and AL. As discussed in MCD #1969, some intensification of
thunderstorm development is still possible late this afternoon,
particularly across parts of south central through southeastern
Alabama. This intensification may be accompanied by the risk of a
few damaging wind gusts and/or a brief tornado, particularly as the
storms along the front interact with any pre-frontal development. A
similar situation is possible farther west across southern LA and
far southern MS.
.PREV DISCUSSION... /ISSUED 1052 AM CST Mon Dec 06 2021/
...TX to GA...
A large upper trough is dominant across much of the eastern US
today, with the associated cold front extending from northeast LA
into middle TN. Widespread thunderstorms are occurring along and
ahead of the cold front, with occasional clusters of storms showing
sufficient intensification for some concern for damaging winds over
the past few hours. Pockets of heating ahead of the line will
maintain deep convection through the day, with storms moving across
the remainder of LA/MS/AL/western GA. However, low and mid level
wind fields will weaken throughout the day. This is expected to
keep the overall severe threat limited and sporadic. Nevertheless,
the strongest cells across the region will pose a risk of damaging
wind gusts or perhaps a tornado or two. Please refer to Mesoscale
Discussion #1968 for further details.
