  1. I'm going to start a discussion for a slight risk 5% tor for the above area Tues 16th June.

    09Z HRRR confirms earlier RAP in developing one or two decent looking discrete supercells in far NW NE and far E WY at 21Z.
    I like the area between Harrison NE and Lusk WY for shear as the LLJ cranks things up later. Could be a residual boundary to look out for.

     

    Edit: GPS puts you in Lamar now. You could get to far NW NE by initiation but it might be breakfast on the go. An alternative would be to chase upslope in SE WY, but IMO tor risk is lower here.

     

    This begins a three day play in roughly the same region.

  2. Because they have massive ********  :D

     

    The more lightbars the more impotent they are maybe ?

    There is certainly a correlation between ego and the number of antenna (in theory of course).

    I can understand maybe two long antenna (one mifi signal booster and one shortwave radio), but some of the vehicles I saw had over half a dozen of various lengths and floppiness.

    I also wonder at the validity of hazard light gantries. One team (Minuteman disaster response) had blue emergency service lights which may or may not be official.

    If their primary purpose is to follow a tornado damage path and assist if necessary then I could understand it. Although the vast majority of chasers would stop and assist, I fear not all do and of course very few tornados actually impact populated areas anyway.

  3. A sort of 'rest day' then - well deserved!

     

    I know you're not in northeast NE, but the return has been impressive there this afternoon with 80/67 in the Norfolk region just west of the loose boundary.
    I suspect that there will be some interesting weather in the NE corner of NE n the next few hours.

  4. Chaser convergence aside the formation of supercells is somewhat conditional and will rely on regions of clearing in the current blanket. Having said that WV indicates one of the troughs swinging in from the mountains should arrive on cue and overriding any clear slots that heat and destabilise will easily promote towers.

    Note to self - chase next year late May early June as I'd love to see a classic upslope day.

  5. UPSLOPE!

    This should go MDT for both hail and tornados IMO. The RAP has some of the best superimposed EHI and SRH values so far this season, with up to 60kns of speed shear already over the region at 21Z.

    Somewhere between Sterling CO and Osallala NE would be my primary target for lunch reccy

    Update: 9Z models. Maybe further west towards Greeley CO required where initiation likely. The veering profile with height is amazing on the top NE corner of CO later but the LLJ is maximised SW NE.

    Recurrent risk next three days in same area.

  6. Are you guys mobile yet today? The GPS is not showing any movement yet.

    Some towers popping now on the ND/SD line and also down in SW SD - the two areas already highlighted.

    Visibility looks amazing today (maybe 80 miles plus on flat terrain) so no problem spotting the initiation.

  7. 14Z RAP and HRRR:
    I like the WF play but that is way up in ND. I also like the area just east of the lee low/trough pretty much dead centre SD (Murdo, SD) at 22Z where HRRR plops a nice lone sup into a sheared environment. Will it be enough though?
    The south/SW SD region would be better for tomorrow as others have mentioned.

  8. Thanks Nick. The area between Sturgis and Vale, SD again looks favoured this afternoon with the combination of moisture and shear maximised here, especially from 22Z.

    Wide open panoramas make for great viewing, but dirt roads likely.
