Area Forecast Discussion National Weather Service Memphis TN 353 PM CDT Wed May 10 2023 ...New SYNOPSIS, DISCUSSION... .SYNOPSIS... Issued at 317 PM CDT Wed May 10 2023 Wet and unsettled weather will continue through this weekend. Loosely organized storms are possible on Thursday as an upper level low lifts across the region. A couple of storms may produce gusty winds and small hail. Hot and humid conditions will persist through Mother's Day with a pattern change anticipated early next week. Drier and cooler air will persist across the Mid-South through late next week. && .DISCUSSION... (This evening through next Tuesday) Issued at 317 PM CDT Wed May 10 2023 Storms have easily exceeded expectations this afternoon. With over 2500 J/kg of MLCAPE available and less than 15 knots of shear, storms have pulsed to severe limits across much of the region. Several microbursts have occurred across the region today and have mainly caused damage to trees and power poles. A couple instances of large hail have also occurred. Additional instances of damaging winds and large hail are possible through early evening along with isolated flooding reports. Intensity of storms should subside by sunset with the loss of daytime heating. Another band of showers will lift across the region overnight, but should not be a cause for concern. The next round of showers and thunderstorms will arrive tomorrow afternoon as an upper level low lifts across the region. A few strong storms are possible as MLCAPE values approach 2000 J/kg once again. Convection becomes a bit more scattered Friday through the weekend as no appreciable forcing mechanisms will be in place across the region. The main story will be heat and humidity. Highs will be approaching 90 each day with overnight lows around 70F. By early next week, the upper level pattern will shift as the ridge sinks south and a large upper low invades the eastern half of the U.S. This will help push a cold front through the region on Monday. As a result, cooler and drier air will filter into the region Tuesday through late week. Expect highs in the lower 80s and lows in the lower 60s. The next chance of rainfall will arrive next weekend as a cold front moves into the region. AC3 && .AVIATION... (18Z TAFS) Issued at 1259 PM CDT Wed May 10 2023 Showers and thunderstorms will continue along an outflow boundary this afternoon into the evening hours. Generally VFR conditions will prevail through tonight outside of convection, but IFR ceilings and gusty winds are possible with any storms. This activity will diminish this evening, though scattered showers will be possible overnight, mainly over eastern AR. A lull in precipitation is anticipated on Thursday morning but we do expect low clouds to fill in across the Mid-South during this period. Wind speeds will generally remain below 10 kts.
