6/16-6/18 Severe Weather

[nvck]

Looking like another impactful stretch of weather coming up, with Wednesday, as of now, having the highest ceiling. StormNet, CSU-MLP, and other ML products have all had very "hot" runs lately, pretty eyecatching stuff, especially as the northern bound of the highest prob area is over the same area that saw several tornadoes on Thursday. The GEFS has been consistent in showing an area of high P[SCP>1] over portions of Missouri and Illinois, even back into Kansas, for multiple runs now, while other models expand the risk further east towards Ohio. Regardless, very strong flow for this time of the year will overlap an area of ample moisture. Should be an interesting couple days.

As of right now, this looks like an outbreak over potentially a large expanse of real estate, with both strong tornadoes and a derecho possible. I’m amazed at how strong the LLJ is across many models right now.

Miss south for mby, glad to see IL staying hot tho

[nvck]

hoping we get some more of an east trend, am pretty tired of getting 2am weakening MCSs, would at least like to see some lightning in the daytime

More of a march/april look here than anything else, but loving the shear profile

Nice baroclinic support so far into June with the GEFS, EPS, and AIFS ensemble means all showing a 992-995mb low traversing southern Lake Michigan late Wednesday.  Looks like most likely a cool rain for MBY.

I couldn't chase last Thursday due to being in Cleveland on a family trip (probably would have ended up on the still-tornadic relative junk in western IL anyway), but it'd be nice to have the target not be south of I-80 for once since I rarely can take PTO on short notice from my job.

Multiple models are showing a large MCS traversing Iowa again the morning of the event.  Will be interesting to see how the evolution of that affects the development later in the day.  

Very impressed by the synoptics of this.  Powerful upper jet knifing in with very impressive shear profiles over a wide area on the nose of that.

The 12z Euro… holy moly.

Wagons north?

 

[Chicago916]

When all is said and done, Peoria to NWI gonna be the hot spot again. 

[nvck]

gonna go ahead and call a miss north/west here, and will hopefully be proven wrong

Yep.  Might as well head towards Pontiac to Kankakee and camp out there until the event lol.

18Z NAM and RRFS-A (I know, I know, but they're the only mesoscale models that go out that far) edged a little bit north with the warm sector for Wednesday evening.

I'm not even really sure how to process this potential day-4 threat (Wednesday.) The 500mb jet streak is much stronger than average, surface low pressure is lower than most pressure I've seen in June, other than hurricanes.

GFS seems to want to bring the WF into the Metro.

The low starts off as 995mb near Alberta then deepens and stays <990mb for the rest of its trek zonally across the continent. I take it that is highly unusual.

3 day 30% hatched right along the I70 corridor...

06z RRFS suggests that this may be more of a Thursday event for us, blowing up a cell right over the metro by midday. will be interesting to see what the 12z suite thinks, but I could see the d4 risk being shifted back west some
