    2018 Short to Medium Range Severe Thread

    Chased two different times yesterday being so close to home. Initially went WNW after the first storm to move NE through Kane county that was outflow dominate the entire time I was on it from about NW of Kaneville to east of Burlington. Then ended up going back home only to go back out when new storms were developing south of ARR/I-88 coming northward. Let that ARR storm continue northward to Elburn, letting that go with eyes on the two smaller storms SW of ARR/hwy 30. Positioned SW of Big Rock, a little south of hwy 30 and lapsed the organizing low topped supercell (the southern storm of the two was the one to eventually take off.) It had a lot of good rising motion and inflow feeders into the updraft region and what looked like a little meso hand off early on as a new base and eventual lowering/wall cloud developed to the NNE of where I was, more so along the forward flank almost. I finally stopped lapsing and got back in my car as the left side of the wall cloud really began to spin. Hauling back north across hwy 30 and on a few gravel roads, the area of interest was a big bowl shape wall and the entire thing was spinning. I really believe if surface temperatures were a little warmer/steeper low level lapse rates, this storm would've put down a really sizable tornado as it had the look like it wanted to (the Manhattan storm I believe had slightly warmer surface temps and had better low level structure/clear slot and that was even closer to a really nice large cone tornado.) Anyways, I eventually got back to a north/south road (Dauberman rd) and continued north as really nice funnel formed as the meso hit the boundary and stretched that thing as much as it could. I was looking NW when I took the picture below, on Dauberman rd just south of Kaneville, IL. Another chaser was quite close and had video of ground contact/swirl circulations in a field next to him to confirm that it was a brief/weak tornado. All in all a cool little day and my first tornado in my home county.

    2018 Short to Medium Range Severe Thread

    The parameter space on the NAM is still impressive, more so than previous few runs while the nest has a different solution but given its at its end range I would toss that until we get closer. The potential Tuesday is probably the best we've seen across northern Illinois this year, as we should have plenty of flow with the upper low around...but a lot of ways for things to not work out. See if that makes it to Twitter

    The 18z NAM is interesting and fairly impressive from DVN-ORD on Tuesday

    Short-Term Severe/Flooding Discussion

    Victor Gensini and myself will be out tomorrow in probably northeast KS as it looks now. We are leaving tonight for DSM. Synoptically, it looks like a really nice setup but the CAM's aren't really having it and seem to be really struggling with storm mode/morphology. The 18z NAM came in even stronger with the mid-level streak owing to even better bulk shear values coupled with big CAPE, dew points in the upper 60's, backed surface flow and very steep mid-level lapse rates.

    Central/Western Medium-Long Range Discussion

    Victor Gensini and I have 5/14-5/25 blocked off for a trip to the plains, dependent on the pattern of course.
  9. #TeamJoe Today being %15 hatched is lol worthy. Let's be honest. Save those for sure fire tornado setups and possible tornado outbreaks. Not this crap lol

    February 8th-11th Overrunning Event

    Finished with 4.0" at my house for this round. 11.1" for the weekend event. 30.3" on the winter with 17" of that in the last nine days.

    3.0" here at MDW

    February 8th-11th Overrunning Event

    1.0" in last hour here at MDW for a total of 2" in little over 3 hours. ASOS had 0.05" liquid in that last hour as well so a 20:1 ratio in that time period.

    February 8th-11th Overrunning Event

    Finished with 6.2" total for the first event. Kinda screw hole potential with bigger totals in every other direction. Puts me over 25" for the winter total and over 12" since Sunday.
