ST. LOUIS, MO — The dry weather of the past few days will come to a fast end starting Thursday as the moisture associated with Tropical Storm Gordon surges north into the region. One of our more reliable long-range forecast models is predicting from 2" to 5" of rain across the entire region starting Thursday and ending Sunday morning. These numbers look very reasonable considering how much moisture is already available.
There will be a few scattered storms around Thursday but the "big event" will be Friday and Saturday. The rain should wrap up late Saturday night.
Heavy rain and flooding is possible late this week into the weekend as the remnants of tropical storm Gordon interact with a stalled front over the region. Stay tuned for updates. #mowx #ilwx #midmowx #stlwx pic.twitter.com/cy5MTB2pjd
