February 21 Potential Severe Weather Event

The Storm Prediction Center has outlined an area of severe weather for Day 6, or February 21st.

Prognosis... Strong storm system will be ejecting from the Rockies on the 20th-21st. As the storm system moves east, the subtropical jet stream and Pacific jet stream will merge into a single, powerful jet stream that will be centered over the outlined region. Current thinking is that the abundance of moisture and strength (albeit weakening) of the storm system will provide a base for severe weather on the 21st. Tornadoes and damaging winds would certainly be possible, but model uncertainty forbids me from making any definitive conclusions on threats for this day.

I will have more updates in coming days.
