Thanks...I haven't started a topic in like three years.

I'm trying to extend the dates for this thread since there's slight risk across much of the forum on 6/30 and 7/1...but not sure how to do it. Can an admin update?

Nice couplet south of Springfield.

Going to be a Moderate Risk.

Started a thread for today’s action. Threat seems substantial enough.

The 11z HRRR run tho

NWS Storm Prediction Center Norman OK 0758 AM CDT Thu Jun 29 2023 Areas affected...Portions of northern MO...extreme northeastern KS...and far southern IA Concerning...Severe Thunderstorm Watch 413... Valid 291258Z - 291430Z The severe weather threat for Severe Thunderstorm Watch 413 continues. SUMMARY...The threat for significant damaging winds up to around 80 mph will likely increase this morning across northern Missouri. DISCUSSION...A couple of supercells and bowing clusters are ongoing this morning across far northeastern KS, southwestern IA, and northern MO. The most intense cluster is across northwestern MO, where a recent measured wind gust to 68 kt (78 mph) has been observed. As the boundary layer continues to destabilize with diurnal heating, the very strong instability (MLCAPE 3000+ J/kg) and steep low/mid-level lapse rates will support an increasing threat for significant severe downdraft winds up to around 80 mph. The greatest threat for these substantial damaging winds will likely focus across northern MO where the primary bowing cluster should consolidate. Isolated large hail may also occur with any embedded supercells.

SPC has introduced a 30% hatched area for wind across N MO, Central IL and SE IN. There are already watches out in Missouri. Destructive MCS/possible derecho becoming increasingly likely today.

Ah, yes, breaking news: the sky is blue.

Overcast and hazy here. Weird combo.

Ran into work to help with storm coverage. Ended up with some broad rotation overhead. Pretty good!

The downside to discrete sup’s is some people are going to get split by the cells. I’m afraid I’m going to be some people.

Storms have popped.

It’s got that “feel” to it. Sun out, strong southerly winds (30 mph gusts), warm but not too hot. Initiation will be real close here.

Hoping storms initiate in time tomorrow to see some severe wx. Worried about a miss east.

A fair amount of smoke in the upper levels this morning. It appears to be overcast at first glance but there are no clouds in the sky. The sun is nice and red.

This is my fave weather. 50's and 60's and overcast. Wish it could be like this every day in the summer...save the occasional derecho.

I have no idea how long-range HRRR handles smoke but Friday morning looks like it could be bad particularly in Ohio, but also Southern Michigan and Northern Indiana.

Good video of the Carroll County landspout.

I don't think I've ever seen one of these in our neck of the woods: BLOWING DUST WARNING NWS LINCOLN IL 125 PM CDT MON MAY 1 2023 ILZ051-052-061-020000- /O.NEW.KILX.DU.W.0001.230501T1825Z-230502T0000Z/ 125 PM CDT MON MAY 1 2023 Sangamon-Christian-Shelby- ...BLOWING DUST WARNING IN EFFECT UNTIL 7 PM CDT THIS EVENING... * WHAT...Visibility less than one quarter mile in blowing dust. * WHERE...Sangamon, Christian and Shelby Counties. * WHEN...Until 7 PM CDT this evening. * IMPACTS...Severely limited visibilities are expected.

Turn the lights all the way off and keep your foot off the brake pedal. Remember, Pull Aside, Stay Alive. $$

Meanwhile we're working on setting records here at home:

Nasty dust storm in Central Illinois south of Springfield has caused a massive pileup on I-55. https://www.facebook.com/WICSABC20/videos/1226438338073741

Stood in the garage while the squall line came through. Winds gusted to about 40 mph. Heavy rain. Some good CG's. Nice spring storm.

Pretty lame so far.
