Area Forecast Discussion National Weather Service Memphis TN 236 PM CDT Sat Aug 24 2019 .DISCUSSION... The moist and unsettled pattern will continue over the Mid-South into the middle of next week. Periods of showers and thunderstorms are expected. A cold front will move through the area mid to late next week, bringing drier and somewhat cooler air and reducing POPs. Tonight through Tuesday: Primary focusing mechanisms for precip will be stalled surface front across northern MS/eastern AR, and upper level impulses moving across. Guidance is in agreement moving a weak system across the area tonight. Expect diurnal showers/storms to persist into evening, with another round of precip developing or moving NE into the area by daybreak Sunday. A more substantial upper system will approach the Mid-South Sunday into Sunday night. Support from this upper system will lead to a more widespread round of precip. Severe weather threat is low, but locally heavy rain with very moist airmass (PW greater than 2 inches) may occur. Will include in Haz Weather Outlook for Sunday and Sunday night. Guidance is a little slower to take upper system out of our area, so will nudge higher POPs farther west on Monday. Monday night should be quieter, with cold front due to arrive on Tuesday. GFS seems a little quick with the front, so will trend toward the NAM timing but bring higher POPs to our NW counties by 12Z Tue. POPs increase areawide on Tuesday, with environment more supportive of organized storms along/ahead of front. Will keep "strong" wording in HWO. Will keep lingering POPs Tuesday night as the front and storms exit the area. Wednesday through Saturday: Mainly dry conditions expected behind front, with drier and somewhat cooler air settling in. GFS and ECMWF suggest a reinforcing front toward the end of forecast period, with GFS again faster. GW && .AVIATION... 18Z TAFs A slow-approaching upper disturbance over AR, a tropical airmass and numerous surface boundaries will provide chances for TSRA through early evening. Initial cluster of TSRA will likely develop along an NW-SE boundary extending from south of MEM to south of TUP at midday. This activity should lift north, possibly followed by additional SHRA/TSRA clusters lifting north through north MS into early evening. Despite loss of surface heating this evening, SHRA chances will continue this evening and overnight, ahead of upper level trof that will drop into the Midsouth on Sunday. TS cannot be ruled out during any portion of the next 30 hours, but will favor warmer periods of the day, from 15Z through 23Z Sunday. PWB && .MEG WATCHES/WARNINGS/ADVISORIES... AR...None. MO...None.
