SPC Mesoscale Discussion: Severe Potential… Watch Possible

| May 9, 2019 @ 12:04 pm

SUMMARY…Locally damaging winds will remain possible over the next couple of hours across the northern and central Alabama vicinity. A new WW is being considered.

DISCUSSION…Latest radar loop shows a continuous/arcing band of thunderstorms moving east-northeastward across northern and central Alabama at around 25 kt. Within this fairly well-organized band, locally damaging winds remain possible — particularly near smaller-scale bowing/rotating segments. Over the past hour, a reports of some wind damage have been received from within the line. Though limited instability (500 J/kg mixed-layer CAPE) is indicated, and with extensive cloud cover ahead of the storms likely to impede additional/appreciable CAPE development, the band of storms appears to be well-organized enough, with just enough thermodynamic support, to continue posing some risk for damaging winds over the next couple of hours, as storms cross Alabama and eventually approach the Alabama/Georgia border. A severe thunderstorm watch is being considered for this area.
