✔️Summary…
•As a storm system moves through the region, a cold front will sweep across the state between Sunday morning and Sunday night. Accompanying this front will be a forced squall line/QLCS, which will traverse the state. This setup is a high shear/kinematic and low instability/thermodynamic type of setup, one that often favors limited lightning production from activity. Severe t’storms will be possible with this activity, some significant, with damaging winds and a few tornadoes being the main threats.
