  1. Steep lapse rates with some CAPE surprised me with some pea size hail. It was probably 10% rain 90% hail which was unique.
  2. Gnarly cell coming out of the radar site.
  3. The eye is trying to come back.
  4. Really clear eye now with high clouds all around. Possible mesovortices even?
  5. I can't see this not being officially a storm at 5am EDT. Not sure if I've seen a storm form this quick. I know the east side is pretty clear but the center look intense.
  6. A few storms did form around St Paul. Easy to see way. Sounding might be contaminated by the cold front passing by as the balloon was launched.
  7. One of the most defined cold fronts I've seen. No storms though.
  8. There hasn't been much severe weather to follow as of late. Maybe this weekend will be active. Classic bowling ball on Sunday.
  9. A couple of funnels reported. Nothing on the ground.
  10. Nebraska and Colorado have had tornadoes today with a 0% risk posted. Minnesota to do the same?
  11. Already a day3 enhanced highlighted. Models hint this could be high end event. ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE UPPER MIDWEST... ...SUMMARY... Scattered severe thunderstorms should occur Saturday across parts of the Upper Midwest. A few tornadoes, large to very large hail, and significant damaging winds all appear possible. ...Upper Midwest into the Great Lakes... A notable shortwave trough is forecast to progress from the northern Plains east-southeastward across the Upper Midwest and Great Lakes on Saturday. A belt of enhanced mid/upper-level flow will likely accompany this shortwave trough and act to organize thunderstorms that develop ahead of it through the day. There is reasonably good agreement in model guidance that a very moist low-level airmass will be in place ahead of a front across the Upper Midwest Saturday morning. Steepening mid-level lapse rates and robust heating of this airmass through the early afternoon should foster moderate to strong instability. Deep-layer shear will be more than sufficient for organized updrafts, and supercells with a threat for very large hail appear possible with initial convective development across MN. Most guidance also suggests that quick upscale growth into a MCS will occur Saturday afternoon/evening with eastward extent into western/central WI and northeastern IA. Given the degree of buoyancy available, at least scattered damaging/severe winds appear probable as this mode transition occurs. Some of these winds may be significant. Have included an Enhanced Risk where MCS development and propagation appear most likely. Enough low-level shear associated with a southwesterly low-level jet is also forecast to support a threat for a few tornadoes. This severe threat should continue into the Great Lakes region Saturday night, but lesser instability forecast with eastward extent should keep the overall severe threat fairly isolated.
  12. Day 3 enhanced. One of the most extreme forecast soundings I've seen
  13. Both storms have had CC drop but NWS hasn't called them radar confirmed.
  14. Up to 6 total warnings, 4 different rotations. Maybe a quick spin up.
  15. Several QLCS rotations and 70 mph winds possible.
