27 Storm Track meteorologist Branden Borremans forecasts a nice Tuesday, numerous showers and storms developing Wednesday morning and ending before midnight, showers and storms Thursday evening and night, scattered showers and storms Friday, a few showers later Saturday, and a few showers possible Monday.

We are gearing up for another possible severe weather day in Eastern Iowa and Western Illinois.

On Friday, the risk of severe thunderstorms will pick up where storms leave off from Thursday night. We also have a boundary that has set up between Hwy 20 and Hwy 30 which will serve as focal point for storm formation later if we do get the necessary energy from the sun.

Friday afternoon into the evening may see isolated storms south of I-70. This area will be in the wake of a mid-level trough, with height rises and perhaps subtle subsidence aloft. Large hail and damaging winds will be the primary threat.

According to a broadcast report to the National Weather Service, more than one-thousand customers lost power in Scottsbluff, with several trees snapped in half during strong storms.

A watch means conditions are ripe for a damaging storm to develop - defined as a storm carrying one-inch hail, 57.5 miles per hour winds or a tornado.

There is a tornado threat for a good portion of mid-Missouri, but it remains a low threat.

The Storm Prediction Center has upgraded much of Northwest Arkansas to an "Enhanced" risk of severe storms, and brought parts of the River Valley up to the "Slight" risk. for Friday and Friday night. Highs will be in the mid-upper 80s and slightly more humid on Sunday.
