Area forecast discussion, Jun 2, 3:00 PM CDT, 1 hour 54 minutes before
Area Forecast Discussion National Weather Service Memphis TN 300 PM CDT Wed Jun 2 2021 .DISCUSSION... Midafternoon GOES water vapor imagery showed a nearly closed upper circulation centered near Oklahoma City. Warm sector destabilization had increased the coverage east of a surface pressure trof oriented along the MS River. For this evening, expect coverage of showers and thunderstorms to slowly decrease, focused mainly east of the weak surface pressure trof lifting through west TN. Additional showers and perhaps an elevated thunderstorm or two will be possible overnight ahead of a 700 mb trof axis rotating through. Additional showers will likely develop to the north and east of Memphis Thursday, aided by diurnal heating and cooler temps aloft, near the base of the upper trof. To the south, a midlevel dry slot should result in lower coverage of showers and thunderstorms, relative to today. Upper ridging will prevail Friday behind the exiting trof. An elevated mixed layer (EML) based around 750mb should cap most if not all deep convection, in the absence of any significant bulk shear. Temps Friday should warm to seasonal values, under scattered cumulus, and with light winds. For the weekend, attention turns to the a closed upper low over south TX. If mid and high level clouds downstream of the upper low aren't too thick, the erosion of the EML should allow for the return of diurnally-enhanced isolated showers and thunderstorms. Rain chances should progressively pick up a Sunday and Monday, as the upstream upper low lifts into the north TX, and the western Ozarks, respectively. Storm coverage will continue the diurnal trend each day, peaking in coverage from midafternoon through early evening. Embedded in the upper ridge and surrounded by weak steering flow, the upper low will become nearly stationary while gradually weakening through the middle of next week. At this early time, it's a bit unclear where the remnant energy will end up. But it does appear it will provide sufficient weakness in the upper ridge for diurnally-enhanced showers and thunderstorms over the Midsouth. Temps should average near normal, with areas of brief local cool-down near thunderstorm outflows. PWB && .AVIATION... /18z TAFs/ Showers and thunderstorms will persist through the evening. CIGs will slowly deteriorate from MVFR to IFR. Coverage is low at this time so confidence is too low to put TEMPOs. Later tonight into tomorrow morning, fog will be a threat to the TAF sites. CIGs will improve by tomorrow afternoon. SWB && .MEG WATCHES/WARNINGS/ADVISORIES... AR...None. MO...None. MS...None. TN...None. &&
