I'm not the biggest severe wx fan, but it's hard not to be interested with how crazy this event is, especially for December.

james1976 Posted December 15, 2021 Report Share Posted December 15, 2021 Its long but if you have a couple mins check out Des Moines afternoon AFD. Crazy stuff. Key Messages: An unprecedented, historic event is just getting started across the area today. There are several facets to this event including extreme environmental winds, high end severe weather, and (of least importance) record breaking heat. Lee cyclogenesis has rapidly increased as the surface cyclone moves out of Colorado and into Nebraska and Kansas this afternoon. Iowa has remained within the warm sector today with temperature soaring into the upper 60s to mid 70s across the area. This shatters high temperature records for the day across most sites in Iowa. Additionally, the all-time, statewide December record high of 74 degrees in Thurman of 74 on Dec. 6, 1939 is broken (preliminarily, this will need to be officially verified). Dewpoints at 1pm were in the upper 50s and low 60s statewide. Significant High Wind... Warm air advection ongoing today has initially limited mixing efficiency as was expected, as the lift from waa works in contrast to deep mixing. Even still, winds by noon had started gusting 40-50+ mph across parts of southern into central Iowa. Convection has begun across Kansas and Nebraska and is expected to swing across Iowa between 22z and 02z. Thunderstorms will enhance background wind gusts, but more on the convective component next. Hi-res models continue to indicate a brief lull in gusts behind the line of convection this evening, however this will only last an hour or so before the synoptic winds ramp up with vigor. As the low pressure center and associated dryline approaches the area the pressure gradient will tighten significantly across the area. Strong cold air advection and subsidence will pull the very strong winds just off the surface down to the ground. It can be practically guaranteed that everyone will see 60 mph gust this evening and many will see 70 mph. Strong decent on the back of the low resulting in a sting jet setup mean that gusts of 80+ mph are possible in pockets across the state. Gusty winds will begin to subside after midnight. Widespread wind damage an power outages are a real possibility. Severe Thunderstorm Threat... This is the first time that SPC has ever issued a Moderate risk for severe storms in the state of Iowa in December, and even in the typical convective season they are fairly uncommon). Thunderstorms will enhance the background strong environmental winds as cold pools drive gusts. Embedded gusts within severe thunderstorms will easily exceed 80 mph and gusts over 100 mph are certainly possible. Wind gusts are easily a concern with every storm that develops. The other concern is the tornado threat. Parameters within the CAMs include 0- 1km MLCAPE ~800 J/kg, 0-1km helicity ~300m2/s2, LCLs ~500m, Sig Tor Parameter ~1-2, and 0-1km lapse rates 6-8 C/km, all contributing to a good tornadic environment. As the previous discussion mentioned, storms will be moving very fast (current storms in Kansas are moving at 70-80 mph) and rotational winds within tornadic storms will be enhanced, easily pushing strength to the significant tornado (EF2+) thresholds. 1 3 Quote Link to comment Share on other sites More sharing options...
