Area forecast discussion, Jun 7, 6:51 PM CDT, 38 minutes before
Area Forecast Discussion National Weather Service Memphis TN 651 PM CDT Mon Jun 7 2021 .DISCUSSION... Updated for aviation discussion && .PREV DISCUSSION... /issued 344 PM CDT Mon Jun 7 2021/ Showers and sub-severe thunderstorms are ongoing across much of the Midsouth with the greatest concentration and strongest storms over north Mississippi. Cloud cover and showers have kept temperatures in check across portions of the Midsouth, though brief breaks in clouds have resulted in quick spikes of temperatures into the low 80s. Storms should weaken after sunset but due the presence of a weak upper level low at least showers should continue through the night. Tomorrow, the Storm Prediction Center has included much of the Midsouth in a marginal risk for severe thunderstorms. Storms will likely be diurnally enhanced during the afternoon hours and could result in localized damaging wind. The upper low will begin to shift away from the area late tomorrow, but much of the Midsouth will remain on the east side of a broad trough. As a result more rain and thunderstorms will continue through midweek, and possibly through Friday. The risk of strong or severe storms looks low. Portions of the Midsouth may see 2-3 inches of rainfall over the next several days. Since the rain is spread over multiple days we do not plan to issue a watch immediately, but depending on where storms track, one may eventually be needed. Temperatures are expected to remain seasonably mild through the work week, but may trend a degree or two warmer by Friday. Expect highs in the low to mid 80s through Thursday and in the mid to upper 80s Friday. Next weekend, guidance shows a ridge trying to build in from the west. As a result, expect afternoon highs back in the upper 80s to near 90 degrees and less rainfall. 30 && .AVIATION... In the short term expect a line of SHRAs/TSRAs to track north into KTUP and KMEM this evening with ocnl IFR conds and some potentially gusty winds. CAMs have line weakening as it moves toward KJBR and KMKL so went with VCTS for now. Expect low clouds to redevelop area-wide late tonight with more SHRAs/TSRAS pushing into the area late tonight into early Tuesday. Expect cigs to gradually lift to VFR once again by tomorrow afternoon with scattered SHRAs/TSRAs continuing. Since morning precip seems focused in the MEM-MKL corridor seems probable that the afternoon might be quiet vs more activity across the KJBR/KTUP areas. At least that is the thinking for now. South winds 5-10 kts tonight...higher in TSRAs...becoming a little stronger tomorrow at 10-12 kts with higher gusts. SJM && .MEG WATCHES/WARNINGS/ADVISORIES... AR...None. MO...None. MS...None.
