brettjrob Posted June 15, 2013 Share Posted June 15, 2013 Thunder_road, is your chase group still in Colorado? Just curious. I might chase storms for 30 miles (ish) today. The HRRR has been adamant since early this morning that a supercell will evolve roughly from CYS-IMP this evening. Should be an easy, close chase for you if it verifies. I was half tempted to haul it down I-80 toward that area after yesterday's chase, but didn't like the straight-line hodographs, so opted to head home. This probably guarantees amazing structure and/or a Campo-like fluke tornado. Upslope convection beginning to develop along the Laramie Range the past 20 minutes or so.

Chinook Posted June 15, 2013 Share Posted June 15, 2013 Before all of this happened, I was thinking of driving to one of those gas stations at one of those exits on I-80 (maybe by Burns), right next to where that cell is. I just didn't want to drive that much. I had enough driving on Thursday when I chased a pretty small storm, and then hit the Greeley US 34 traffic at rush hour. On that day, I think I discovered the cattle yard that makes Greeley stink so much. It is a big cattle yard. I almost gagged. Link to comment Share on other sites More sharing options...

It got really dark outside, much like the day of the tornado, so some people were pretty freaked out. In the end it poured down a ton of rain with visibility only a few hundred feet at that. Lots of flash flooding and a few water rescues. I still don't understand why people try to drive through floodwater. Link to comment Share on other sites More sharing options...
Thunder Road Posted June 16, 2013 Share Posted June 16, 2013 Thunder_road, is your chase group still in Colorado? Just curious. I might chase storms for 30 miles (ish) today. We were out in Weld County today with about 50 other chasers (it felt like) including one tour company that had absolutely no chase etiquette. Goodland, KS now. I have almost absolutely no feel on tomorrow. And after a check of the 4 km NAM, NMM, ARW, SPC WRF and NSSL WRF...neither do the hi-res models.

Chinook Posted June 18, 2013 Share Posted June 18, 2013 this is a tornado warned storm with a very high-reflectivity RFD and pretty obvious rotation near Brush, Colorado. There might be a tornado debris signature on the CC. (not sure.) Link to comment Share on other sites More sharing options...
Thunder Road Posted June 18, 2013 Share Posted June 18, 2013 Tornado in Kit Carson Co. Bogus. We had a completely unimpeded view of the base when the warning was issued, and we saw nothing. SPC report is a rain-wrapped landspout, which doesn't even make sense. However...still quite the picturesque storm! Link to comment Share on other sites More sharing options...

jojo762 Posted June 27, 2013 Share Posted June 27, 2013 Tomorrow looks fairly interesting... appears that a significant severe threat could develop over Central/ Eastern KS in the afternoon and evening hours possibly continuing overnight across SE KS/ NE OK/ SW MO... Per the SPC D2 1730Z Outlook looks like a few semi-discrete to possibly discrete cells will develop, and eventually merge into a severe mcs and be capable of producing very-large hail, and significant damaging wind gusts, forecast soundings across the area are supportive of this idea, showing a very dry air column with the classic summertime Inverted-V which is typically indicative of very strong thunderstorm related winds... All WFO's (TOP/ICT/EAX) appear to be on board with this threat. Tornado threat would appear rather low ATTM given Surface LCL's AOA 2000 AGL and Temp/DP spreads in the 30 to 40 degree range would generally expect storms to be high-based, however should storms become surface based a tornado or two could be possible given the environment with 40-55kts of Bulk Shear, and CAPE values of 4000-5000 J/KG, capping shouldn't be an issue either with models trending cooler at 850 hPa... Main issue ATTM would appear to be the lack of any strong forcing mechanism... Also FWIW the NAM is showing 0-3KM EHI values to be in the 3 to 7 range across Eastern Kansas, and on this occasion the NAM is not an outlier and is in decent agreement with other models... Seem like an upgrade to a Moderate Risk could be warranted eventually as exact details become more obvious given the expected damaging wind threat-- which could be potentially widespread, as well as the initial threat for very-large hail, and a tornado or two.
