11:47 a.m. - National Weather Service issues a particularly dangerous situation tornado watch for portions of northern and central Missouri and western Illinois until 8 p.m. Friday.

RELATED: Here's what to do if you hear a tornado siren

A potent area of low pressure is making its way into the Great Plains Friday morning. It has produced heavy rain, gusty winds and mountain snow since it moved in from California.

That system is heading our direction. 

The first round of showers moved through early Friday morning. Those storms were not severe, but now that they have moved on, we'll have a dry rest of the morning. With sunshine getting through the clouds Friday morning, that could mean thunderstorms reach their full potential later Friday afternoon and evening.

The storms that form this afternoon have the potential of putting down large hail, the size of golf balls. Even gusts over 70 mph are possible along with a tornado or two. The greatest threat is from 2 p.m. until 8 p.m.

Alert Day Friday

Early Friday morning the Storm Prediction Center upgraded the St. Louis area into a moderate risk of severe weather Friday afternoon and evening. The confidence is increasing that we could have several storms in the 5 On Your Side viewing area possible of producing dangerous, life-threatening weather through the afternoon and evening.

The first storms should form around lunchtime and thereafter. Thunderstorms should become more widespread as the afternoon rolls along.

These storms will be moving fast and could drop a tornado or two very quickly. If any tornadoes do form, they have the potential of becoming long-tracked, large tornadoes. At the onset of the storm development large hail is also possible.

As the storms push eastward, they should form into a line and that line will have the potential of producing damaging, gusty winds over 70 mph, especially in Illinois.

The fast-moving storms will be racing northeast during the evening and should be out of our area by 10 p.m. at the latest.

As this weather system pulls away, gusty winds will turn to the northwest. The strongest winds will be overnight Friday into early Saturday.
