Area forecast discussion, Dec 6, 5:02 AM CST, 9 minutes before
Area Forecast Discussion National Weather Service Memphis TN 502 AM CST Mon Dec 6 2021 .DISCUSSION... /issued 439 AM CST Mon Dec 6 2021/ Cool, dry and seasonal early December weather will prevail across the Midsouth through midweek, following this morning's cold frontal passage. Strong northerly winds will lighten overnight, but probably not go completely calm, as surface high pressure settles into Illinois. These light winds and dry air (lower to mid 20s dewpoints), should preclude fog/freezing fog formation late tonight. Fast zonal flow aloft will prevail until a weak upper trof passage early Wednesday morning. This feature should pass through the area dry, given the lack of return flow moisture in the Midsouth. Main impact would be an increase in midlevel clouds. Zonal flow an low amplitude ridging will prevail Thursday and Friday, with strengthening low level return flow. Milder overnight lows will accompany increased surface dewpoints. A few showers will also be possible, aided by warm advection. A progressive longwave trof remains on track to pass from the plains into the MS River valley on Saturday. This feature will bring our next appreciable rain chances, and perhaps a few strong storms. Dry conditions should for Sunday, with upstream ridging set to move into the Midsouth early next week. PWB && .AVIATION... 12Z TAF Set Convection along and ahead of a cold front will continue to sink southeastward across the Mid-South this morning. IFR/MVFR conditions will occur with the convection. Expect conditions to improve to VFR pretty quickly behind the front. Gusty Northerly winds will occur behind the front as well. Expect speeds sustained at 12-16 KTS with gusts up to 25 KTS. Speeds will begin to diminish around sunset as the direction begins to shift to the NE. KRM && && .MEG WATCHES/WARNINGS/ADVISORIES... AR...None. MO...None. MS...None. TN...None. &&
