ST. LOUIS, MO (KTVI) - Saturday continues to be a day to remain "weather aware." Heavy rain, flash flooding and some severe weather will be possible at times.

The heavy rain event continues as rain with thunderstorms are slowly shifting north/northeast with a warm front Saturday morning. Overnight, the heaviest rain has been near and 20 miles either side of a line from Salem, MO over to near Carbondale, IL. Within our viewing area amounts range from 1" to 4" so far with the highest amounts south of metro St. Louis.

The pattern is slowly modulating a bit with the warm front trying to refocus heavy rain and storms more to the west and northwest. While showers and storms are tapering off to the southeast they will continue for much of the day along and north of I-70 in Illinois and along, northwest of I-44 in MO.

A lull in the precipitation may develop late Saturday morning in many areas. It may not end completely, but it should ease up and become somewhat more scattered vs the widespread coverage we've seen since last night. The lull will be short-lived as new storms should rapidly develop by mid-afternoon over central and southwest Missouri and spread northeast across the entire region. These storms may be severe with large hail and damaging winds and a threat for tornadoes exists as well...especially from metro St. Louis to the south and southeast. It will all depend on the how far north the warm front can get and that remains very uncertain at this time.
