Mesoscale Discussion 2168 NWS Storm Prediction Center Norman OK 0618 PM CDT Wed Oct 30 2024 Areas affected...portions of eastern KS and western Missouri Concerning...Tornado Watch 695... Valid 302318Z - 310045Z The severe weather threat for Tornado Watch 695 continues. SUMMARY...A broken squall line continues to slowly mature near the eastward advancing cold front. As these updrafts organize, they will remain capable of damaging wind gusts and a few tornadoes. DISCUSSION...As of 2315 UTC, regional radar imagery showed a long broken band of storms near a cold front stretching from northern MO, into northeast and east-central KS. So far, this line has remained on the cool side of the front, with numerous bursts of likely elevated convection. Over the last hour, composite radar imagery and satellite have shown some intensification of the convection as it has started to overtake the front in spots. The environment across northeastern KS is broadly unstable with 500-1000 J/kg of MLCAPE and 45-50 kt of deep-layer shear. Plenty sufficient for continued storm organization into a QLCS mode, storms should slowly strengthen as they quickly track east northeast this evening. A few more isolated cells have also been noted on a subtle confluence axis ahead of the primary squall line. Intensification of these incipient storms into supercells is possible given favorable thermodynamic/kinematic parameter space, though highly uncertain. Given the primary linear storm mode, the main severe risk is likely damaging winds. Strong mid-level flow will aide in downward transport of strong wind gusts, some potentially as high as 75-80 mph. However, low-level shear is also strong and expected to increase this evening with the intensification of the low-level jet. VAD data and 00-02z RAP forecast soundings show enlargement of hodographs is underway, with 0-1km SRH of 250-300 m2/s2. This will support a risk for a few tornadoes. Despite the messy storm mode, an isolated stronger tornado will also remain possible should a more established supercell develop given the very strong low-level shear. ..Lyons.. 10/30/2024 ...Please see www.spc.noaa.gov for graphic product...
