Crazy supercell. Overall a reminder of the season we're now in. Also pretty concerning that 1000-1500 sb/mlcape verified. It's reasonable to expect that tomorrow, too. The question then will become if cells will exist to take advantage of that.

I feel this supercell has been flirting with the line between PDS warning and tornado emergency. Might be getting close to the latter now. Probably pretty densely populated area because this isn't that far east of Des Moines.

Mesoscale Discussion 0197 NWS Storm Prediction Center Norman OK 0533 PM CST Sat Mar 05 2022 Areas affected...Parts of central and southeastern iowa Concerning...Tornado Watch 27... Valid 052333Z - 060130Z The severe weather threat for Tornado Watch 27 continues. SUMMARY...The tornado threat will be focused in parts of central and southeast Iowa this evening. This threat may extend beyond the WW 27 and an additional downstream tornado watch will likely be considered this evening. DISCUSSION...A strong supercell continues to move through southern suburbs of Des Moines. This storm has had consistent rotational velocities in the 55-70 kt range over the past hour. Other discrete storms are moving out of north-central Missouri into south-central Iowa. At least one tornado was reported in Wayne County, IA, with this activity. These storms are moving into a similar environment and will continue to pose a threat for tornadoes over the next 1-2 hours. To the west of these discrete storms, a more broken line of convection has developed along the cold front. This activity will pose greater threats for large hail and damaging winds than tornadoes. Farther to the north and east, earlier cloud cover and precipitation has limited destabilization. For parts of eastern Iowa and perhaps far northeastern Missouri, an additional downstream tornado watch will need to be considered this evening. ..Wendt.. 03/05/2022
