A strong, slow moving storm system will move through Missouri this weekend bringing a chance of severe storms and heavy rain which could lead to flash flooding. Waves of rain and storms will move across Mid-Missouri from late Friday night through Sunday afternoon.
The first round of storms will move north from near I-44 to I-70 from 1 to 6 AM Saturday. There is a severe threat mainly south of HWY 50 with these storms for possible large hail the size of quarters or greater. These will also produce pockets of heavy rain. These will weaken by sunrise and rain will decrease.
Rain will increase from mid-morning Saturday through mid-afternoon with steady periods of moderate to heavy rainfall before tapering off toward evening. A warm front will lift north to near HWY 54 Saturday evening and storms will likely form along this boundary. These could become severe with main threats large hail and damaging wind. An isolated tornado is also possible Saturday evening in the slight risk area which is mainly along and south of HWY 54.
Periods of rain continue from Saturday night through Sunday afternoon. Storms are possible Sunday afternoon, mainly along and east of HWY 63. There is a marginal severe storm threat for areas east of HWY 63 for isolated large hail or damaging wind.
Flooding is likely this weekend as rainfall amounts increase. The ground is saturated and high rainfall rates will cause runoff into creeks, streams and rivers, causing rivers to rise. Smaller tributaries will quickly flood. Also, low lying areas and roads will flood where heavy rain occurs. Remember not to drive through flooded roads and be aware of rising rivers.
