Area forecast discussion, Aug 8, 12:46 PM CDT, 1 hour 35 minutes before
Area Forecast Discussion National Weather Service Memphis TN 1246 PM CDT Sun Aug 8 2021 .DISCUSSION... Updated for aviation discussion && PREV DISCUSSION... /issued 328 AM CDT Sun Aug 8 2021/ Current temperatures across the Midsouth range from the middle 60 near Paris, TN to the middle 70s near Memphis. Morning lows will likely be the coolest temperatures we will see until this time next week. Sunrise temperatures should be in the middle 60s to low 70s. Expect fairly typical August conditions across the Midsouth today through the upcoming work week featuring morning temperatures in the middle 70s and highs in the middle 90s. Surface high pressure and a broad ridge over the Southeastern US and Southern plains will keep us warm and dry. No large scale organized precipitation is expected, but showers and thunderstorms are possible each afternoon. Showers/storms should diminish after sunset each day. Moisture levels will creep up after today resulting in afternoon heat indices between 105 and 109 for most of the Midsouth Monday through at least Thursday. Guidance has been pretty consistent bringing a cold front into the area late in the work week or early in the weekend. The latest guidance is a bit slower with the front, so we may see heat indices near 105 again Friday. Hopefully we will see at least a little relief from the heat next weekend. 30 && .AVIATION... Isolated SHRAs/TSRAs expected this afternoon otrw VFR conds. An upper trough pushing into the mid MS Valley will kick off TSRAs across MO overnight. Some CAMs are pointing to the possibility of this activity sliding south into the region overnight so will need to watch. For now added a VCTS at KJBR/KMKL late tonight. Depending on how that convection evolves will impact how Monday unfolds. For now it looks like activity will diminish early followed by a relatively quiet day. Winds will be generally southerly and a bit gusty during the late morning and afternoon hours across the Delta. SJM && .MEG WATCHES/WARNINGS/ADVISORIES... AR...None. MO...None. MS...None. TN...None. &&
