Area forecast discussion, Nov 21, 11:56 AM CST, 3 hours 20 minutes before
Area Forecast Discussion National Weather Service Memphis TN 1156 AM CST Sun Nov 21 2021 .DISCUSSION... Updated for aviation discussion && .PREV DISCUSSION... /issued 1020 AM CST Sun Nov 21 2021/ UPDATE... Added some thunder to the forecast for today's line of showers. Despite minimal instability, we've still seen a few lightning strikes and rumbles of thunder in the approaching line over eastern AR this morning. Added a slight chance of thunderstorms throughout the day as the system progresses across the Mid-South. Rest of the forecast is on track. CAD DISCUSSION.../issued 329 AM CST Sun Nov 21 2021/ It's 15-20 degrees warmer across the Mid-South this morning than it was 24 hours ago. Most of the area is in the upper 40s to middle 50s. South winds are boosting moisture levels across the area ahead of another cold front approaching the Midsouth. Most of the area should warm into the 60s or even near 70 degrees today, but some of the coldest temperatures of the Fall are on our doorstep. Rain showers will overspread the Midsouth early today. No strong or severe thunderstorms are expected. Most of the area should see around a half of an inch of rain. Rain will come to an end tonight with cooler air filtering into the area. Surface high pressure will build across the Southeastern US Monday with a ridge shifting out of the Plains over the Mississippi river valley Tuesday. As a result, dry and cool conditions are expected Monday through Wednesday. Our coldest temperatures so far this Fall are expected Tuesday morning when all of the Midsouth should drop below freezing. Portions of Northwest Tennessee could drop into the lower 20s. High temperatures should rebound into the low 60s by Wednesday. After midweek, weak southwest flow will set up across the area. Another cold front will usher in a chance of rain showers Thursday resulting in another one-half of an inch or so of rain. Subfreezing morning temperatures are expected again Friday and Saturday with highs in the mid 40s to mid 50s. Next weekend looks dry. 30 && .AVIATION... MVFR conds are widespread across the area in advance of a cold front moving into the region. Expect conds to lower to IFR for a few hours this afternoon into this evening. There is some elevated instability north of I-40 and as a result there have been a few TSRAs. Given latest CAMs will add a VCTS for KMEM and KTUP later this afternoon into this evening. South winds will shift to N at 10 kts late this afternoon into this evening and conds will improve to VFR this evening. VFR with N/NNE winds at 10-12 kts on Monday. SJM && .MEG WATCHES/WARNINGS/ADVISORIES... AR...None. MO...None. MS...None. TN...None. &&
