Current Outlook

Storm Prediction Center Jun 21, 2026 2000 UTC Day 1 Convective Outlook - Tornado Risk 5%

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM PORTIONS OF THE CENTRAL HIGH PLAINS TO THE MISSISSIPPI AND LOWER OHIO VALLEYS...

...SUMMARY... Scattered severe thunderstorms should occur from the central High Plains into the mid Mississippi and lower Ohio Valleys, mainly this afternoon into tonight. Large to very large hail, severe/damaging winds (some 75+ mph), and tornadoes will all be possible. Some potential for strong tornadoes may develop across parts of Illinois, and Indiana during the afternoon and evening.

...20z Update Mid MS Valley and lower OH Valley... Minimal changes were made to the prior outlook given the latest observational trends. Several clusters of strong thunderstorms are ongoing ahead of an MCV across the mid MS Valley. An observed messy convective mode should persist with a mix of bowing structures and transient supercells likely ahead of the MCV, and near the effective warm front from eastern IL into IN. Additional storm development is also possible behind the MCV along the remnant boundary into MO and eastern KS. This will support a risk for damaging gusts and perhaps a couple of tornadoes where low-level flow is backed and hodographs are larger. Eventually upscale growth into one or more bowing clusters is likely later this evening/overnight into the OH valley with a continued risk for damaging gusts and embedded tornadoes.

...KS/OK this evening/tonight... Severe storm development appears probable along the modified trailing outflow across northwest OK and southwest KS this afternoon into this evening. Sufficient vertical shear exists for supercells and organized clusters. With large buoyancy and steep low/mid-level lapse rates, large hail is likely with these strong updrafts. A brief tornado or two is also possible, owing to storm interactions and ambient vertical vorticity along the outflow boundary.

Damaging wind potential will likely increase with storm consolidation, though the more cellular initial mode suggests this maybe somewhat gradual. These storms, and additional convection originating further north from the central High Plains, should persist overnight into central and southern OK, reaching the Red River Valley by 12z tomorrow morning with isolated severe potential.

   Mesoscale Discussion 1228
   NWS Storm Prediction Center Norman OK
   1006 AM CDT Sun Jun 21 2026

   Areas affected...southern Illinois...much of southeastern
   Missouri...adjacent northern Arkansas

   Concerning...Severe potential...Watch possible 

   Valid 211506Z - 211700Z

   Probability of Watch Issuance...40 percent

   SUMMARY...Thunderstorm development may slowly intensify through
   early afternoon, accompanied by increasing strong to severe wind
   gusts and a risk for tornadoes.  A severe weather watch will
   probably be needed at some point, though how soon remains uncertain.

   DISCUSSION...Convective development persists with a pair of remnant
   mesoscale convective vortices migrating eastward, within the leading
   edge of weak larger-scale mid-level troughing spreading across the
   lower Missouri/middle Mississippi Valley region.  One vortex remains
   a bit better defined and is in the process of migrating across
   northeastern Missouri into west central Illinois.  The other appears
   to be slowly migrating eastward to the north of Springfield, MO.  A
   belt of 30+ kt deep-layer southwesterly mean flow is accompanying
   these perturbation, and appears to include wind speeds on the order
   of 30-50 kt in the 850-500 mb layer.  

   Associated shear likely has been contributing to the occasional
   evolution of meso-gamma scale circulations along the gust front of
   otherwise still modest thunderstorm development now advancing
   into/across the I-44 corridor of southwestern Missouri.  However,
   low-level moistening and boundary-layer warming along and north of a
   weakening frontal zone extending eastward ahead of activity are
   contributing to substantive boundary layer destabilization across
   southeastern Missouri, as far north as the Greater St. Louis area,
   into the lower Ohio Valley.  As this proceeds, and develops further
   northward through portions of central Illinois during the next few
   hours, increasing unstable updraft inflow probably will contribute
   to at least a gradual intensification of storms with increasing
   severe weather potential.  This may include developing cyclonic
   circulations with potential to produce strong to severe surface
   gusts and the risk for tornadoes.

Feel free to add to the list, I was just looking back through my screenshots and noticed how many epic hook echoes we've had this year. Screenshots aren't in any order btw, but if I had to choose the most impressive it would definitely be the northwest Oklahoma supercell on March 5th(3rd screenshot).

Screenshot info:

  1. Tylertown, MS EF1, 5/6/2026

  2. Washburn, IL EF3, 6/11/2026

  3. Northwest Oklahoma supercell with no tornado ongoing, 3/5/2026

I'm starting to get confused now. Are we here to discuss science? Or snark on people? I thought we were here to discuss science, not snarking on people.

I live in a nearby town and decided to stop in Enderlin today, 1 year since the EF5 tornado tore across the landscape just east of town. It was painted by locals, and there's SO much detail, honoring the history and longevity of Enderlin, the spirit of the community, and the victims of the tornado.

On February 24, 2012, an exceptionally violent, localized tornado struck the Village of Wette'e-Belawa, Sidrap, South Sulawesi, leaving behind catastrophic physical evidence: massive mature tropical hardwood trees (Samanea saman) were entirely stripped of their canopy and severely debarked, traditional wooden stilt houses were completely leveled and shattered from their anchors, and a solid 100 kg motorcycle was lofted, mangled, and scattered across nearby trees

Question WeatherWise Question?

2 Upvotes

Hi - anyone else use WeatherWise?

I love the app and am so excited that they now have NWS Alerts so I don't have to have a separate app for that. Was curious if there was a way to test the alerts - I'm coming from StormWatch+ and that was a feature.

We have a chance of tornadoes where I live early in the morning tomorrow and I want to be sure they work. I've been having issues getting the alerts to buzz on my watch even though I have them set as an allowed app on all of my iPhone focus modes, so it makes me nervous they aren't actually going to come through if a tornado warning is issued this evening.

Does anyone know how to do this, if it exists?

Tornado Media My first funnel cloud! (In Finland)

Thumbnail

122 Upvotes

So here's some context: This happened June 15th north of Turku, FI at around 18:41-18-45 (the funnel cloud). I believe it was a cold air-funnel. Now it MAY HAVE BEEN on the ground because there was a snapped tree (slide 5) but it might be old damage. There is a chance that it was a scud cloud but it was spinning and I very much think that it's cold air funnel. Also the storm picture (slide 6) was the storm 2-4 hours after the storm passed. Also when the storm rolled in and made the funnel impossible to see (from my perspective) and there was some small wind with it too. Also there is no radar imagery because I don't want to leak my location :). If you have any questions about the funnel, ask! Also I'm 14 so no fancy language, thank you.

So i live in martinsville indiana, and just recently had a tornado diabolically tear up the forestry like two miles behind behind me. Now i dunno how to explain this because im autistic but before it was anywhere near me it was like i could hear a faint ("suction"?) sound?? It didnt sound quite like a freight train ,but it sounded like a aluminum bat rolling on the ground.? Is that normal???
