Area Forecast Discussion National Weather Service Memphis TN 1222 PM CDT Wed May 25 2022 .DISCUSSION... Updated 18z Aviation Discussion. && PREV DISCUSSION... /issued 349 AM CDT Wed May 25 2022/ DISCUSSION... A wet night across the Mid-South. Latest KNQA radar scan reveals good coverage of showers and thunderstorms across the majority of the Mid-South. Dual-pol radar rainfall rate estimates have been rather light overnight, ranging from 0.5 to 1 inch per hour, with isolated pockets of 2 to 3 inches per hour. Showers have begun to train mainly along and west of Interstate 55 over the past hour. If rain rates do increase in the short term, the flooding potential will increase as we approach sunrise. The current day 1 excessive rainfall outlook still includes a moderate risk along and east of the Mississippi River with a slight risk across the rest of the area. Normally, a moderate risk would trigger a flood watch, but due to more than expected uncertainty, the risk looks more isolated than widespread. Will continue to advertise in the HWO and through our messaging channels. The main closed upper low, currently near the Oklahoma Panhandle, will slowly move east throughout the day today. As it does, several weak shortwaves embedded in southwest flow will translate into the Mid-South. This will result in a few more rounds of moderate to heavy rainfall. PWATs around 1.8 inches, MLCAPE values between 500 and 1500 J/kg, and weak lift will all contribute to a low to medium threat for additional heavy rainfall today. Nonetheless, a few areas could experience flash flooding this afternoon and evening, especially in urban areas. A cold front will move into the Mid-South tonight and serve as a focus for additional rainfall tonight through Thursday afternoon. The main trough will finally lift out of the region on Friday. This will bring a return of dry weather and near normal temperatures. Expect highs in the upper 70s with lows only in the 50s Friday and Saturday morning. A warming trend will begin Sunday and continue through the middle of next week. Expect highs around 90 and lows in the lower 70s. AC3 && .AVIATION... /18z TAF/ Showers and thunderstorms will continue to push through the Mid- South throughout the day today. Expect lower CIGs with gusty south winds. By this evening the intensity of convection should subside a bit but with continued low CIGs. Conditions should finally become VFR by the end of the period. SWB && .MEG WATCHES/WARNINGS/ADVISORIES...
