Area Forecast Discussion National Weather Service Des Moines IA 616 AM CDT Tue Jun 21 2022 ...Updated for the 12z Aviation Discussion... .DISCUSSION.../Today through Monday/ Issued at 354 AM CDT Tue Jun 21 2022 Key Messages: - Heat Advisory southeast today. - Isolated to Scattered storm chances south this afternoon. A strong storm is possible. - Storms possible Thursday night and Friday. Strong storms and heavy rainfall are possible. Surface boundary has entered northwest Iowa with convective outflow preceding the front. Some convection has initiated along the outflow over north central and back into west central Iowa. This convection is well elevated above the current elevated mixed layer in place. This convection should diminish over the next few hours though it is possible it will continue to bubble in vicinity of the boundary into the mid-morning hours. The main cold advection is still lagging and will remain in vicinity of far northwest Iowa then will move slowly into the northwest half of Iowa including central Iowa into this afternoon. The main forecast challenges are temperatures and heat index values today and storm chances. How far south the impacts of the outflow have and the potential for mostly cloudy conditions in vicinity of the boundary leave some uncertainty on the heat especially over the Des Moines metro area. That said, with the warm start and pooling dew points along the boundary, good confidence in location of the current heat headlines with the Des Moines metro currently out of it. Cooler conditions over the northwest where the higher heat has been the past two days. Convective chances by this afternoon are still a bit hazy. Strong instability will develop over the southeast with MUCAPEs in excess of 3000 J/kg are expected. Still the EML a loft will be slow to erode and with the lack strong forcing outside of the slow moving boundary, it may be difficult for more than isolated initiation to occur near the boundary. Meager deep layer shear will be in place with limited speed shear and no directional shear so the potential for organized activity is low. Still any storms will have a damaging wind threat with collapsing cells and higher 0-3 km theta-e differences in the 25-30K range, suggesting the potential for cold pool development. The hail threat could develop with accelerating updrafts through a deep layer but will be limited due to higher melting levels. Trends for convection overnight are shifting southward but still possible additional storms reach far southern Iowa as the 850 mb boundary arrives along with the short wave rounding the upper high just to the south. More pleasant and mostly dry conditions are expected for Wednesday and Thursday. Still monitoring storm potential for Thursday night and into Friday though at this time, it appears the main area of activity will be north of the state early then a better chance late Thursday night and into Friday as a stronger short wave and increasing instability arrive. Strong storms and perhaps heavy rain will be possible with this activity. A long wave trough will enter the Northern Plains Saturday/Saturday night along with an attendant cold front. This will bring another chance for thunderstorms and again strong storms and heavy rainfall could occur. This will be followed by a seasonably cool Sunday then gradual warming and mostly dry into early next week. && .AVIATION.../For the 12Z TAFS through 12Z Wednesday morning/ Issued at 613 AM CDT Tue Jun 21 2022 A boundary will move through the area today and bring a gradual switch to northwest winds. The wind will be gusty at times, especially this morning over the northern sites. There are thunderstorm chances late this afternoon and evening, mainly near KOTM. Otherwise, VFR conditions will prevail. && .DMX WATCHES/WARNINGS/ADVISORIES...
