Central States Weather: "Slight Risk" of Severe Thunderstorms- Tornadoes Later Today- Friday


A
strong low pressure center and it's attendant frontal systems will bring an increase in shower and thunderstorm activity later today and tomorrow across the Central States- and a few of those thunderstorms could become severe later this Thursday afternoon and evening into Friday.


Note that the low pressure center located this morning in northeastern Nebraska is almost as strong as the storm that produced last Saturday's long-track tornado in Mississippi.


According to the NWS' Storm Prediction Center (SPC)  and the graphic- today's "slight risk" of severe weather comes generally across parts of the northern and western Central States: Iowa- Kansas and Nebraska.


Forming first could be individual- "supercell" thunderstorms that could produce large hail and perhaps a tornado or three.

The risks for the various types of severe weather are shown in these SPC graphics- tornadoes- severe hail and wind probabilities.

The storms that do develop are forecast to gather into clusters or short line segements overnight into Friday morning- the latter being the best time for storms in the Metro Kansas City area.

Friday's SPC severe risk area is larger- including the Metro as well as taking in the rest of Iowa- Missouri- eastern Kansas- Oklahoma and Arkansas.


As always- any watches issued will be posted here at CSW.
