AREA FORECAST DISCUSSION National Weather Service Sioux Falls SD 240 PM CDT Sat Jul 22 2023 .SHORT TERM...(This Evening through Sunday) Issued at 240 PM CDT Sat Jul 22 2023 A relatively weak wave will continue to drop south through MN into IA late this afternoon and evening. With some weak low to mid level warm advection and a weaker cap late this afternoon isolated thunderstorms will be possible. With CAPE values generally 1000 J/kg or lower and fairly weak shear severe weather is not expected to be very widespread. However, with a very dry sub cloud layer leading to DCAPE values around 1200 J/kg there could be some gusty winds with the stronger storms, possibly as high as 65 mph. Hail could reach dime size. The better chances for this will be mostly near and east of I-29. This activity should be mostly diurnally driven so not much activity expected after sunset. There is some potential for an isolated thunderstorm near the Missouri River in central SD as well as a few locations have heated out. Lows will be mild in the upper 50s to lower 60s. Northwest flow aloft with building heights should lead to a dry and increasingly warm Sunday. Model soundings show a very strong cap in place in most locations, weakest in central SD, so not expecting storms to develop. Highs from the mid 80s in southwest MN to the mid 90s in central SD. .LONG TERM...(Sunday Night through Saturday) Issued at 240 PM CDT Sat Jul 22 2023 Sunday night into Monday morning a wave will drop south into the area and increase the mid level warm air advection. This should allow for isolated to scattered thunderstorms to develop, with the better chances near and east of I-29. While isolated severe storms will be possible the overall threat should be on the lower end. Monday afternoon and night looks dry for now but if the wave is a little slower or if any boundaries are left behind additional activity will be possible. Temperatures start to climb on Monday with highs from the mid and upper 80s east of I-29 to the mid 90s in central SD. Tuesday into Saturday will see upper level ridging try to build into the area but some weak energy may occasionally beat the ridge down a bit. One potentially better piece of energy looks to be from about Wednesday night into Thursday night, but still far enough out not to worry too much about details. Otherwise very warm with lows from the mid 60s to lower 70s and highs in the 90s. && .AVIATION...(For the 18Z TAFS through 18Z Sunday Afternoon) Issued at 1225 PM CDT Sat Jul 22 2023 Isolated showers and thunderstorms will be possible this afternoon into the evening, but most activity should diminish pretty quickly after sunset. The better chances will be near and east of I-29. The stronger storms later in the afternoon may produce strong wind gusts to 65 mph. Outside of any showers and thunderstorms VFR conditions are expected. && .FSD WATCHES/WARNINGS/ADVISORIES... SD...None. MN...None. IA...None. NE...None. && SHORT TERM...08 LONG TERM...08 AVIATION...08
