NWS Memphis, TN wrote its last area forecast discussion before the first event at Jun 2, 10:40 PM CST, 1 hour 35 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Memphis TN 1140 PM CDT Sat Jun 2 2018 .UPDATE... Updated for 06Z Aviation Forecast Discussion below. && .PREV DISCUSSION... /issued 943 PM CDT Sat Jun 2 2018/ UPDATE... Have updated to extend the Severe Thunderstorm Watch through midnight for most of the E Arkansas counties. The storms currently in NE Arkansas continue to pose a large hail and damaging wind threat as they move to the SE. Still anticipated to begin weakening over the next couple of hours. ZDM PREV DISCUSSION... /issued 755 PM CDT Sat Jun 2 2018/ UPDATE... Currently, showers and thunderstorms are ongoing to the NW of the CWA in association with a surface cold front. The front currently extends roughly from NW Arkansas northeastward through S Illinois. These storms are currently discrete out ahead of the front, but are expected to congeal into a line as they progress further SE. Latest mesoanalysis places a tight instability gradient roughly along the MS River, with much more stable air present over W TN, with much lower 850 hPa RH values there indicating the presence of dry air contributing to a more stable atmosphere. This coincides well with the latest runs of the HRRR, which bring a line of storms SSE through the CWA, a cold pool propagating along the instability gradient. The latest HRRR run brings the storms through the Memphis metro between 11 PM and midnight. The storms will be capable of producing large hail, with damaging winds a secondary threat. Latest thinking is NE Arkansas and the Missouri Bootheel stand the best odds of severe storms, as the storms will likely wane in intensity as they move to the SE. Have updated POPs to account for the latest timing. Confidence in timing and strength of the line of storms remains limited at this time. The Severe Thunderstorm Watch remains in effect for E Arkansas and the Missouri Bootheel through 10 PM. ZDM PREV DISCUSSION... /issued 244 PM CDT Sat Jun 2 2018/ DISCUSSION...Surface analysis this afternoon places a cold front from Northwest Missouri back through Eastern Kansas and West Texas. A hot and humid airmass is in place across the Lower Mississippi Valley this afternoon with temperatures as of 2 PM CDT in the upper 80s to lower 90s with surface dewpoints in the 70s. Severe thunderstorm potential for the remainder of the afternoon into the evening will be the primary focus in this afternoon's forecast issuance. Regional WSR-88D radar trends have indicated the development of a scattered line of showers and thunderstorms just ahead of a cold front. A Mesoscale Convective Vortex (MCV) over Missouri is providing additional lift over the region. The lift produced by this feature and the cold front combined with a very warm, moist, and unstable airmass will support the development of showers and thunderstorms across the Mid-South into tonight. Short term models including Convective Allowing Models (CAMs) indicate showers and thunderstorms will continue to develop and push across Arkansas for the remainder of the afternoon and affecting portions of East/Northeast Arkansas and the Missouri Bootheel until early evening. This convective activity is anticipated to reach the Mississippi River between early to evening, and across the remainder of the Mid-South late evening into the overnight hours. Some uncertainty remains between the models on timing and coverage and will be closely monitored as the event unfolds. Surface based CAPE values in excess of 3000 J/kg, steep 700-500 mb layer mid- level lapse rates around 7 C/km, and 0-6 km Bulk Shear values around 40 kts support the potential of some strong to severe thunderstorms across the region late this afternoon into tonight. Damaging winds is expected to be the predominant threat along with a secondary threat of large hail. Localized heavy rainfall may also be possible with these thunderstorms. Slightly cooler and drier air will filter into the Lower Mississippi Valley into early next week. Long term models indicate an upper level ridge will attempt to build across the region into much of next week. However, much of the region will remain on the eastern periphery of the upper level ridge axis placing the Mid- South within northwest flow aloft. Confidence in shower and thunderstorm chances next week remains low as models differ on timing of individual mid-level shortwave troughs and the strength of the ridge. Consequently, have leaned toward isolated rain chances until models come into better agreement.
