Area Forecast Discussion National Weather Service Memphis TN 502 AM CST Sun Jan 9 2022 .DISCUSSION... /issued 447 AM CST Sun Jan 9 2022/ Southwesterly flow aloft prevailed over the Midsouth early this morning, in advance of a partially-phased deepening neutral-tilt northern branch and a positively-tilted southern branch trofs. West/southwest upper level flow overspread modified tropical maritime airmass over the Midsouth, characterized by precipitable water values near 1.4 inches, and modest elevated instability rooted between 900mb and 850mb. The northern and southern branches likely to consolidate into a deepening longwave trof over the eastern CONUS on Monday. In the interim, the positive tilt nature of the southern branch trof will dictate a relatively slow cold front passage through the Midsouth into early afternoon. As mentioned in the 0911 UTC WPC mesoscale precipitation discussion, there is some concern than storms will being to train along and ahead of the front, with convergence focused ahead of a frontal wave lifting into north MS through midday. After this wave passes to the east, the cold front will pick up speed through the afternoon, with stronger winds driving south through the delta. Deterministic and probabilistic 90th percentile QPF suggest flooding threat will remain localized. For Monday, it's back to cold and dry midwinter weather, under northwest flow aloft. The pattern will deamplify through Tuesday, as the eastern US trof lifts offshore. After a quick transition to zonal flow aloft, additional upper level energy will dive southeast out of the central high plains, carving out another transitory longwave trof over the eastern CONUS. This compact wave likely will pass through the Midsouth with little other than increased cloudiness on Wednesday. For the late week periods, 00Z medium range guidance exhibited wider than expected spread, limiting forecast confidence. It appears that a southern branch cut-off low over the desert southwest will be less of a factor, while the models indicate to varying degrees, a stronger northern branch shortwave dropping south into the plains and MS River valley, representative of a colder pattern for the Midsouth by next weekend. PWB && .AVIATION... 12Z TAF Set Showers and thunderstorms will continue to spread into the Mid-South this morning. Expect IFR conditions with the convection. The convection will gradually shift toward the southeast over the course of the day. Behind the convection and the passing cold front, conditions will improve to MVFR and eventually VFR. Gusty southerly winds will switch around to the North behind the front. Speeds will remain around 15 KTS sustained with gusts up to around 25 KTS. Speeds will gradually diminish during the overnight hours. Low level wind shear will continue to occur ahead of the front. KRM && && .MEG WATCHES/WARNINGS/ADVISORIES... AR...None. MO...None.
