NUCAPS Around The Dryline

The NUCAPS profiles did a good job resloving the dryline in southwestern OK. Profiles for an area to the east of the dryline (top) and west of the dryline (bottom) are shown below.

The profile to the east of the dryline had a surface temperature and dewpoint about 10 degrees below surrounding obs. Prehaps unsurprisingly, the profile west of the dryline had temperature and dewpoint at the surface much closer to relaity. I was however surprised at the number of points that passed the QC check, especially to the east of the dryline where clouds were prevelant.

Also of note was the moist layer evident on both soundings around 400mb. This matches a moist layer found on 12z and 18z soundings around the area.

NUCAPS 1850Z ICT

 

NUCAPS sounding from SWRN ICT indicates we had continued very steep lapse rates through the middle and upper portions of the column. Hail threat expected to continue.

Severe Thunderstorm Warning #4 - Oklahoma

The storm that prompted the severe thunderstorm warning #2 continued to show the potential of severe weather. Both radar signatures as well as ProbSevere and the Lightning jump algorithm show this possibility.

-Toki Wartooth

Enhanced Helicities Noted in Vicinity of Outflow Boundary

Helicity values of near 200 M2/S2 were reflected well in the SRSOR visible imagery, particularly for cloud heights that reached into the mid-levels of the atmosphere.

Severe Thunderstorm Warning #2 - Oklahoma

Pulled the trigger on the second severe thunderstorm warning of the day. Radar signatures (60 dBZ to -20C, TBSS) began to indicate hail was possible at roughly the same time that ProbSevere jumped to around 80% and there was a 7-sigma lightning jump. I was ready to pull the trigger when I saw the radar signatures, but the ProbSevere and lightning jump gave me more confidence on the warning.

KICT was down for us, but we relayed with OUN on warning (also pulled up the Topeka radar to help).
