NWS Memphis, TN wrote its last area forecast discussion before the first event at Aug 5, 2:27 PM CST, 2 hours 3 minutes earlier.
Area Forecast Discussion National Weather Service Memphis TN 327 PM CDT Fri Aug 5 2022 .DISCUSSION... Showers and storms have diminished over the area this afternoon. Heavy rainfall fell across portions of the area this morning and continued into the afternoon hours in spots. Some places picked up over 3 inches of rain as rain and storms were training and backbuilding over the same areas. The good news is that rain chances will remain in the forecast, but coverage over the next few days will be more limited. Expect a little bit drier day for Saturday and Sunday with highs in the low 90s. We will remain on the outskirts of the Bermuda high allowing moisture to remain abundant in the atmosphere helping those afternoon shower chances. Guidance still points to a front approaching the area by Wednesday or Thursday next week. This would bring another shot of showers and storms to the Mid South. This will bring temperatures down into the 80s and give us more rain to catch up on yearly totals. && .AVIATION... Scattered showers and a few embedded thunderstorms (VCTS) may persist at least into mid afternoon at MEM/MKL/JBR with diminishing chances later this afternoon into this evening. MVFR conditions should also improve later this afternoon into this evening. Patchy fog may develop again at MKL late tonight. Otherwise, VFR conditions expected for the remainder of the period. S/SSW winds 8-10 kts will become light tonight and increase to 7-10 kts on Saturday. CJC && .MEG WATCHES/WARNINGS/ADVISORIES... AR...None. MO...None. MS...None. TN...None. &&
