Severe Storm Possible for Mississippi this coming Wednesday!!!

The Severe Storms Forecast Center continues to indicate that a regional severe weather threat developing late Tuesday/Tuesday night will carry over into at least early Wednesday. A High likelihood for a pre-frontal tongue of low-level moisture characterized by Mid 50s surface dew points to extend as far north as the Mississippi and Ohio RIver confluence at 12z Wednesday and this may contribute to enough instability to maintain a squall line east of the Mississippi River perhaps as far as the western slopes of the Appalachians ahead of a vigorous short wave trough accelerating through the Ohio Valley during the day. Strongly forced convection will be embedded within a very strong mean environmental flow treater than 50 knots capable of supporting considerable damaging wind gusts even if thermodynamic profiles become decreasingly favorable for lightning activity with eastward progression.

South of the Tennessee Valley storm development ahead of the front may become more discrete in the presence of weaker mid-level forcing/greater inhibition. The pre-frontal deep layer shear is expected to remain favorable for supercells as far south as the central/eastern Gulf Coast.

Upstream waves progressing through the prominent belt of westerlies across the southern tier of the U.S. may support additional risks for severe storm late this coming week into next weekend. At this time the predictability of these systems is too low to confidently delineate additional areas due to the increasingly large spread among model data at this extended range.
