Severe Potential Increasing

The Storm Prediction Center has issued an update to its Day 2 Convective Outlook and includes much of Kentucky in a slight risk for severe thunderstorms. Also, hatched areas for central and western KY from I-65 west indicates an increasing potential for significant severe weather.

Of course, as always, a number of parameters need to come together for this severe weather event to unfold. However, the potential does exist. No need to downplay what may not happen.

Strong winds above the ground, mid 50's dewpoint temperatures, warm surface temperatures will foster a healthy environment for storm initiation and propagation.

However, some things to overcome include precipitation potential from earlier in the day. How quickly can the atmosphere recover with a mid-February increasing sun angle? And will there be sufficient clearing for the atmosphere to destabilize? Any additional showers ahead of the squall may preclude severe weather potential for some.

Nevertheless, the SPC is onboard. Plan accordingly.
