Weather Alert Day: Overnight storms bring flash flooding, wind threat

The ABC 17 Stormtrack Weather Team has issued a Weather Alert Day for the threat of severe storms through Thursday morning.

MIDNIGHT UPDATE:

Strong storms have been training across the eastern half of Mid-Missouri this evening, bringing anywhere from 2-4"+ rainfall to parts of Audrain, Callaway, Boone, Monroe, and Randolph counties. These storms will continue to slowly drift west overnight, bringing the threat of 40 mph winds and heavy rain.

Another complex across far eastern Nebraska and Kansas will move in between 3-4 AM and intersect with ongoing storms. This round of storms will bring the threat of more rainfall and damaging winds through the early hours of Thursday.

This storm system as a whole is moving fairly slow and will dump a lot of heavy rainfall. Localized amounts of 2-4" of rain over a very short period of time could lead to flash flooding issues through Thursday morning.

Synopsis:

Warm, humid air will continue to filter into Mid-Missouri on Wednesday as temperatures rise into the upper 80s to low 90s. Dew points creep past 70 degrees, allowing heat index values to get into the upper 90s by afternoon. There will be plenty of atmospheric fuel available to get storms going, and a cold front sliding in from the north will trigger development likely after 3:00 or 4:00 PM.

Timing/Impacts:

The main threats will be damaging winds between 60-70 mph and heavy rain up to 1" and the potential for flash flooding on roadways. Storms will exit by 11am Thursday.
