...Gusty Thunderstorms with Small Hail and Cold Air Funnel Clouds
through Early Tonight...
Gusty thunderstorms capable of producing cold air funnel clouds
and small hail are forecast through early tonight. These cold air
funnels are developing underneath thunderstorms that are moving
across the area. Underneath these showers...spinning columns of
air that look like tornadoes may continue to develop. These
funnels usually are very brief and rarely touch the ground. If
these funnels do touch down...they most likely will not cause
damage to life or property.
Cold air funnels are due to very cool air aloft...warm moist air
near the ground...and are usually in association with a strong
area of low pressure in the upper levels of the atmosphere. Due to
little or no wind shear...they are usually weak and very brief.
