Thursday Severe Storm Risk


Wednesday Afternoon Update:

The entire Local 6 area is now included in the outlook for an ENHANCED RISK for severe weather for Thursday - Thursday night. This is an upgrade from what the Storm Prediction Center had earlier today. You can also see just below the map what the different risk categories mean to you. See below for timing and additional details.

Wednesday Update:

An active weather pattern continues to bring strong storms to the region this week with a greater risk arriving on Thursday and Thursday night. A strong cold front will move in from the Central Plains and Upper Midwest during the day on Thursday. Ahead of the front, very warm, moist and unstable air will lead to thunderstorm development rapidly Thursday evening. 

The images to the left show the forecast radar imagery for different time periods starting at 6PM on Thursday evening.

The cold front should clear the Local 6 area around Midnight and take the severe weather threat along with it. Damaging winds will be the primary threat with the line of storms but hail and an isolated tornado or two cannot be ruled out, especially associated with storms that develop out ahead of the main line along the cold front. 

Preparedness is important and severe weather safety should be reviewed before storms develop late tomorrow afternoon. Be alert to quickly changing weather conditions throughout the day tomorrow and make sure your weather radio has fresh batteries and is programmed ready to go. 

The Storm Prediction Center has most of our area outlined in a SLIGHT RISK and parts of the area (IL/MO) in an ENHANCED RISK. See the map below:

1AM Thursday Update
: The Storm Prediction Center has upgraded most of the Local 6 area to an ENHANCED RISK for severe weather for Thursday and Thursday Night. The highest likelihood of severe storms remains for Thursday overnight but severe storms are possible dayside as well, just not as widespread. 

Wednesday Evening Update: A stormy weather pattern will set up across our region from Wednesday night into Friday bringing the threat of severe weather and possible flooding. 

A moisture boundary will lift through our area overnight kicking off the first round of storms across the area. Most of these storms will remain below severe limits but will bring heavy rain, gusty winds, and even some small hail. By tomorrow afternoon, scattered storms will re-develop area-wide with a small chance of them becoming severe. 

As a cold front sits nearly stationary near I-64, warm and humid conditions will set the stage for a more organized threat for storms to become severe by late Thursday night. This threat will then continue through Friday morning and afternoon. Damaging winds, large hail, and even an isolated tornado are possible from Thursday night and Friday.

The Storm Prediction Center has outlined all of Southern Illinois, Southeast Missouri, and most of Western Kentucky in the SLIGHT RISK for severe storms on THURSDAY NIGHT and then all of Western Kentucky and NW Tennessee on Friday.

Be alert to quickly changing weather conditions starting Wednesday night. Several rounds of showers and storms will also bring with it higher than normal rainfall totals for parts of the area. Here is forecast look at what will accumulate over a 48-hour period from Wed night into Friday.
