July 3rd Sunday Severe Storm Risk

Please be sure to have a way to receive severe weather alerts for the holiday weekend, especially Sunday and Monday.

Sunday Afternoon Update: A Tornado Watch
has been issued for most of the Local 6 area until 10PM. A warm front sits across Southern Illinois and Indiana allowing for a more unstable air mass across IL/KY this afternoon. The Storm Prediction Center has been watching our region for the past couple of day for the threat of severe storms this afternoon and evening. An isolated tornado is also possible. Damaging winds will be the primary threat with storms that develop. Here is the latest map the Storm Prediction Center put out mid-afternoon. Be alert that conditions will change quickly this afternoon and evening and those who are spending time outdoors or on area lakes should be especially vigilant.

Friday PM Update:
Unfortunate timing with the holiday weekend finally here but a chance of severe storms has crept into the forecast for Sunday the 3rd and Monday the 4th. The Local 6 region is also one of the only areas in the US under the risk of these storms as outlined in the graphic to the right from the Storm Prediction Center.
Damaging winds, large hail, and even an isolated tornado is possible with storms that become severe on Sunday. 
Heavy rain across MO/IL will set in by Saturday night and lift to the NE along a warm front. This warm front will put the Local 6 area in the warm, unstable sector of the storms system moving in from the Central Plains on Sunday. Throughout the morning hours temperatures will grow warmer and the humidity higher. By early to mid afternoon, showers and thunderstorms will develop well ahead of the cold front to our west. These storms will possibly become severe pretty quickly with the heating of the day. The cold front itself will loom back to our west and slowly advance our way Sunday night and Monday the 4th. Scattered showers and storms will continue on and off and some could be strong. The highest risk for severe storms at this point appears to be Sunday afternoon and evening. Flash flooding could also become a risk as storms slowly trek our way along the cold front Sunday night and Monday. A FLASH FLOOD WATCH is in effect for the St. Louis area this weekend if you happen to be traveling there for the holiday.
