Area forecast discussion, May 4, 12:17 PM CDT, 1 hour 45 minutes before
Area Forecast Discussion National Weather Service Memphis TN 1217 PM CDT Tue May 4 2021 .UPDATE... Updated 18z Aviation Discussion. && .PREV DISCUSSION... /issued 426 AM CDT Tue May 4 2021/ DISCUSSION... A busy night across northern portions of the Mid-South at this hour. A line of severe thunderstorms, currently along the Mississippi River, has begun to quickly accelerate and weaken across west Tennessee. Instances of severe wind gusts are still possible, but storm structure looks less impressive now. After this area of storms moves east of the area, we should see a break in convection through late morning. The atmosphere is expected to recover through late morning as temperatures climb to near 80F and dewpoints remain in the 70s. The next round of storms will approach the region from the southwest, as another shortwave lifts out of Texas. Instability will surge to 3500 MLCAPE over north Mississippi and may creep into west Tennessee as well. Latest Hi-Res Convective Allowing Models (CAMs) show storms firing up near the Delta around noon and lifting ENE across north Mississippi and portions of west Tennessee. Bulk Shear will increase to 50 kts, SRH will approach 250 m2/s2, and LCLs will be quite low. The combination of all three will support a healthy tornado risk as well as large hail and damaging winds. Storm mode may start as multi-cellular with embedded supercells and then morph into a loosely organized QLCS or bow echo. All modes of severe weather will be in play this afternoon and SPC's outlined Enhanced Risk covers our area quite well. The threat will diminish by late afternoon as storms push east of the area. A cold front will then approach the area from the northwest around sundown. A few showers and thunderstorms will form along the front, but are not anticipated to be severe as upper level forcing will be rather weak. Behind the front, the Mid-South will see several a nice string of nearly perfect weather days. Expect plenty of sunshine and low humidity. Highs will only top out around 70F for both Wednesday and Thursday. Low temperatures will be quite cool with readings in the upper 40s and lower 50s. A reinforcing front will move through the region Thursday night. With limited moisture in place and weak forcing, just a low chance of rain was carried across the north. Friday will feature abundant sunshine and highs in the lower 70s once again. Return flow will setup across the Mid-South on Saturday, as a large surface low organizes to the lee of the Rockies. A warm front is expected to lift north across the region and a few showers or thunderstorms may accompany the front in the afternoon and evening hours. A weak shortwave is expected to move through the region on Sunday with a chance of scattered storms expected across much of the region for Mother's Day. Unsettled weather will remain over the Mid-South through early next week as a series of shortwaves rotate through the region. AC3 && .AVIATION... /18z TAFs/ Showers and thunderstorms will continue across north Mississippi through this evening. Areas north should have a brief chance of thunderstorm development but TUP has the greatest chance. Winds will remain elevated through the TAF period. CIGs will eventually improve by the end of the TAF period at JBR, MEM and MKL. SWB && .MEG WATCHES/WARNINGS/ADVISORIES... AR...None. MO...None. MS...None. TN...None. &&
