As with any severe weather threat this one has it's uncertainties. The models have been speeding up the timing with each new run. As of this (Thursday) evening Steve Templeton and I have narrowed the severe threat timing down to between 10 am and 5 pm on Friday. We may see a few isolated showers and storms earlier Friday morning but the instablility seems to peak from 10-5. The threat will move from west to east across the viewing area so the threat is highest in western counties like Gasconade, Lincoln and Warren in the morning and in Illinois counties like Clinton, Fayette and Marion in the afternoon.
After that we will be getting a shot of cooler air that will carry us through the weekend with highs in the 60s on Saturday and Sunday.
If a watch is issued for our area or if the Storm Team thinks it's appropriate we will launch into Storm Mode. That means we will have multiple meteorologists on duty in the Storm Center tracking the severe storms and bringing you live, streaming updates on KMOV.com and on channel 4. If you keep KMOV.com/weather open on your desk top you'll have immediate access to the very latest severe weather threats.
