Low Level Jet

The Low Level Jet is comprised of strong winds that are concentrated in relatively narrow bands in the lower part of the atmosphere. It is often amplified at night. The southerly wind over the US Plains states during spring and summer is an example.

In the local region, the low level jet occurs in spring and fall when we get westerly upper level winds at 18,000 feet and southerly winds at 5000 feet from the gulf. This shearing adds moisture that is a key factor in thunderstorms in the midwest. These storms must be watched as they may enter the Gulf region.
