OHweather Posted July 19, 2018 Share Posted July 19, 2018 Did not expect all this today. Over 200 0-1km SRH, strong low-level CAPE and low LCLs...everything sort of maxing its potential thanks to the shear and CAPE being strong in the low levels with low LCLs to boot. Pretty narrow area of good parameters but they are good and stuff is staying discrete. Link to comment Share on other sites More sharing options...

janetjanet998 Posted July 19, 2018 Share Posted July 19, 2018 REAS AFFECTED...EASTERN IOWA INTO FAR NORTHEAST MISSOURI AND NORTHWESTERN ILLINOIS. CONCERNING...TORNADO WATCH 285... VALID 192218Z - 192315Z THE SEVERE WEATHER THREAT FOR TORNADO WATCH 285 CONTINUES. SUMMARY...SEVERAL TORNADOES HAVE BEEN CONFIRMED FROM TWO SUPERCELLS IN EAST CENTRAL IOWA. THE TORNADO THREAT CONTINUES INTO THE EVENING ACROSS THE EASTERN HALF OF TORNADO WATCH 285. DISCUSSION...TWO SUPERCELLS HAVE GENERATED NUMEROUS CONFIRMED TORNADOES ACROSS CENTRAL AND EAST CENTRAL IOWA THIS EVENING. THE TORNADO CONFIRMED IN MARSHALLTOWN, IOWA FORMED AS THE NORTHERN SUPERCELL INTERACTED WITH THE OUTFLOW BOUNDARY FROM THE SOUTHERN SUPERCELL. THIS SUPERCELL HAS NOW WEAKENED SIGNIFICANTLY AS IT MOVED INTO A COOLER AIRMASS EAST OF THIS OUTFLOW BOUNDARY. A TORNADO THREAT CONTINUES ACROSS THE ENTIRE WATCH AREA, BUT THE HIGHEST TORNADO THREAT IS NOW ASSOCIATED WITH THE SUPERCELL MOVING INTO KEOKUK AND WAPELLO COUNTIES WHERE INSTABILITY IS MAXIMIZED WITH MLCAPE AROUND 2500 J/KG.

Really? I think I've seen LSRs labeled as "funnel cloud" that stated funnel cloud halfway to the ground... or something like that. Too bad the building is blocking the view of the ground, but they will be surveying and should find if it really was 2 tornadoes. Link to comment Share on other sites More sharing options...

I dismissed it as a hack vid, but here its the real deal! Once again the significant events are the under-hyped or in this case virtually no hype days. It a rule of thumb. I haven't seen tornado motion like that in July aside from Canadian tornadoes. We can expect more of this strange timing of events because the tornado season wasn't present.

CheeselandSkies Posted July 20, 2018 Share Posted July 20, 2018 Former Pella/Oskaloosa/Ottumwa cell still cranking in the radar hole of west-central IL, about equidistant from DMX, DVN, ILX and LSX. DVN is the closest and still only hitting it at about 10kft. My avatar is from a chase in June 2015 in nearly the same area, starting near Pella/New Sharon. An enhanced risk for hail and wind, 5% tornado probability and tornado watch were in effect, but new updrafts kept going up and disrupting the last one before they could establish strong low-level rotation. It quickly grew upscale into a severe complex as it dove southeast producing wind and hail at/near Oskaloosa and Eddyville. The sunset mammatus on the back side was the highlight of the day.
