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.
