Severe weather tonight?


A line of storms ahead of front moves into the area tonight, does that mean severe weather for us? Well, there is certainly some dynamics for severe weather in place, the heat and humidity of the afternoon are going to add some buoyancy to the atmosphere and a boundary of low pressure will push a squall line of thunderstorms towards the area by late this afternoon and tonight. A strong low level jet will also be present. Here's my thinking, with squall line thunderstorms severe weather is limited by the fast movement of storms. Cumulonimbus cloud tops are cut off by this fast movement making for marginally severe storms. So, while there is a risk of severe weather, and I'm certainly on board with this, dynamics are marginal right now.
