• After witnessing the continued decrease of involvement in the SpotterNetwork staff in serving SN members with troubleshooting issues recently, I have unilaterally decided to terminate the relationship between SpotterNetwork's support and Stormtrack. I have witnessed multiple users unable to receive support weeks after initiating help threads on the forum. I find this lack of response from SpotterNetwork officials disappointing and a failure to hold up their end of the agreement that was made years ago, before I took over management of this site. In my opinion, having Stormtrack users sit and wait for so long to receive help on SpotterNetwork issues on the Stormtrack forums reflects poorly not only on SpotterNetwork, but on Stormtrack and (by association) me as well. Since the issue has not been satisfactorily addressed, I no longer wish for the Stormtrack forum to be associated with SpotterNetwork.

    I apologize to those who continue to have issues with the service and continue to see their issues left unaddressed. Please understand that the connection between ST and SN was put in place long before I had any say over it. But now that I am the "captain of this ship," it is within my right (nay, duty) to make adjustments as I see necessary. Ending this relationship is such an adjustment.

    For those who continue to need help, I recommend navigating a web browswer to SpotterNetwork's About page, and seeking the individuals listed on that page for all further inquiries about SpotterNetwork.

    From this moment forward, the SpotterNetwork sub-forum has been hidden/deleted and there will be no assurance that any SpotterNetwork issues brought up in any of Stormtrack's other sub-forums will be addressed. Do not rely on Stormtrack for help with SpotterNetwork issues.

    Sincerely, Jeff D.

Threat still looks decent...

Unmodified 12Z ETA soundings for 03Z TUE at LAN does indicate some good low level directional shear, but this looks more like a bow echo sounding than tornado... Typically, tornado soundings would yield good directioanl shear all the way through the 0-6KM layer (usually)... Where-as bow echoes usually have the best directional shear located in the 0-3KM layer, with little directional shear above that. Still, supercells often develop in these environments, then transition/morph into bow echoes.

The sounding also shows CAPE values of 2000J/KK, which would definately support severe thunderstorms...
 
That's closer to the track of the upper-level system which is where yesterday's tornadoes were associated.
 
Dewpoints seem to be rising nicely across the region... OBS already show low to mid 60's across lower MI, with mid to upper 60's across WI. The moisture across WI should advect into the region later on this afternoon...

15Z RUC is looking decent, though directional shear is not as good as the ETA was showing (helicity below 100m2/s2), speed shear is still good. Modified the LAN sounding for a parcel of 77F/64F at 00Z, which yields close to 2500J/KG...
 
We got some action in Canada. Chasers in Nova Scotia are reporting isolated severe weather and funnel clouds. Environment Canada has only put some watches up, but it looks like things are going to develop pretty fast. Might want a NOW thread with Canada included.
 
National Weather Service Grand Rapids in their latest HWO at 453 PM EDT still mentions:
AN ISOLATED TORNADO IS ALSO POSSIBLE.
