In addition to the information posted Friday night, here is a look at the latest rainfall projections. Some areas may see locally a little more that what the computer model is showing but this gives you an idea of what to expect as rain moves in late tonight and Monday. Right now there is a threat for storms to become severe to our South but we will be keeping an eye on NW Tennessee and the MO Bootheel to see if any of those storms drift northward amidst the axis of greatest warmth and moisture. I've included the severe storm outlook from the Storm Prediction Center below the rainfall totals. Preparedness reminders are also posted below.
Friday PM Update:Moderate drought conditions have plagued the Local 6 area for most of meteorological Fall (Sep-Nov). As we wrap up the month of November we'll also be in the midst of a heavy rain event set to begin late Sunday and Monday and continue through Tuesday. There is also a small chance of rain on Wednesday of next week. While we certainly need rain we don't need it to come in one big dose.
For the first time in many weeks a feed of moisture from the Gulf of Mexico will be readily available for the sub-tropical jet to transport into our region.
Periods of heavy rain are expected to overspread SE Missouri and Southern Illinois as early as Sunday night. This slow moving band of showers and thunderstorms will then push east Monday and early on Tuesday. A secondary push of moisture may bring another quick round of rain on Wednesday.
This weekend is the time to prepare for rain before it moves in especially if you live near large drainage ditches or low-lying landscape. Recently fallen leaves will likely block proper drainage of heavy rain and cause localized flooding. Clearing drainage areas of these leaves and debris will go a long way to preventing any unnecessary water problems.
