548 FXUS64 KMEG 012346 AFDMEG Area Forecast Discussion National Weather Service Memphis TN 646 PM CDT Wed May 1 2024 ...New AVIATION... .SYNOPSIS... Issued at 345 PM CDT Wed May 1 2024 Dry and warm conditions will persist through Thursday afternoon. Thereafter, a cold front will move into the region and bring unsettled weather to the Mid-South through this weekend. Expect highs in the 80s with lows in the 60s. Unsettled weather may persist through the middle of next week. && .DISCUSSION... (This evening through next Tuesday) Issued at 345 PM CDT Wed May 1 2024 Near record high temperatures are being reported across the Mid- South at this hour. Readings are generally in the upper 80s to near 90 degrees. The latest GOES East Visible Imagery reveals a weak MCV swirling over north central Arkansas. An area of showers and thunderstorms has formed on the northeast side of this feature and is lifting NE in southern Missouri. Some outflow from this activity could move into eastern Arkansas and the Missouri Bootheel, but coverage should remain below 20 percent through early evening. Dry conditions will persist overnight as weak upper level ridging remains in place. A southern stream shortwave will traverse the ArkLaTex Region tomorrow morning and lift north into the Lower Mississippi Valley in the afternoon hours. A decaying MCS over the ArkLaTex may reemerge as an MCV tomorrow afternoon and lift northeast into the Mid-South by late afternoon. With up to 1500 J/kg of MLCAPE on hand and enhanced low level vorticity, a few strong to severe storms are possible late tomorrow afternoon and evening. In fact, a few SHARPpy RAP soundings suggest a marginal threat of damaging winds. This activity will likely persist through at least Friday morning. By Friday afternoon, a cold front will approach the region from the west and likely stall near the I-40 corridor. Scattered to numerous showers and thunderstorms will accompany the front. Another reinforcing front will push into the region on Saturday and keep 30 to 40 PoPs over the region as a result. Unsettled weather will likely persist Sunday into early next week as a series of shortwaves translate through the Lower Mississippi Valley. Highs will generally be in the 80s with lows in the 60s. AC3 && .AVIATION... (00Z TAFS) Issued at 642 PM CDT Wed May 1 2024 VFR conditions will prevail through tomorrow afternoon/evening when an MCV moves into the Mid-South. This MCV is expected to result in an extended period of SHRA and possible TSRA persisting through the TAF period. MVFR VIS and CIGS also appear possible with this activity, but confidence is not high enough to include these details in this TAF cycle. && .MEG WATCHES/WARNINGS/ADVISORIES... AR...None. MO...None.
