Area Forecast Discussion National Weather Service Memphis TN 633 PM CDT Mon Apr 20 2020 .UPDATE... Quick update to account on radar trends and short term guidance. Thunderstorms moving into Northeast Arkansas are likely producing small hail and 25 to 35 mph wind. Increased pops through much of the night to account for ongoing convection and possible additional development. 30 && .PREV DISCUSSION... /issued 624 PM CDT Mon Apr 20 2020/ A weak shortwave within the northwest flow will track across the northern part of the forecast area tonight. This will provide a low chance of showers and thunderstorms well north of I-40 this evening with some hail possible. A stronger system as a surface low and associated upper level progressive trough will move through the forecast area late Wednesday night into Thursday morning. Showers and thunderstorms will likely occur late Wednesday into early Thursday from this system as warm moist advection will fuel elevated convection Wednesday followed by frontal dynamics early Thursday. There is a potential for severe weather Wednesday night into early Thursday with wind and hail the biggest threats and the southern part of the forecast area having a higher threat than the north. Another cold front will provide a chance of showers and thunderstorms Friday afternoon into Friday night followed some showers over the weekend as a cool trough pattern prevails with weak shortwaves moving through the region. SWC && .AVIATION...00Z TAF cycle VFR conditions will continue for the entire forecast period. An area of thunderstorms is currently over northwest sections of the Mid-South.
