The Weather Set-up

For severe storms to develop, the atmosphere needs to have moisture, heat, something to lift the air, storm fuel, and higher winds above the surface.


We will have plenty of moisture in the atmosphere, as humidity increases.  

Once Dew points rise to at least 55°,  the environment is ripe for storms and heavy rain.


Temperatures will warm well into the 60s and low 70s on Friday afternoon. 

Warm air creates buoyancy in the atmosphere and provides energy for storms to tap into. 

Severe Weather

A key ingredient for severe weather is fast-moving air at 5000 feet above the surface; this is called the low-level jet!  The forecast overnight shows winds of 60 to 80 mph over central Arkansas at this level. 


Wind changing direction and speed as you go up in the atmosphere produces “SHEAR”. When shear is in place storms could rotate and produce tornadoes.
