0943 PM CST Fri Mar 06 2026
Areas affected...Northeast Kansas into northern Missouri and eastern
Iowa
Concerning...Tornado Watch 16...19...
Valid 070343Z - 070545Z
The severe weather threat for Tornado Watch 16, 19 continues.
SUMMARY...Some threat for severe hail, wind, and perhaps a tornado,
persists across portions of WW 16 and WW 19 from northeast Kansas
into northern Missouri and portions of eastern Iowa.
DISCUSSION...Latest regional radar imagery depicts most of the
ongoing convection across northeast KS and into western IA being
undercut by a strong cold front. Despite this, GOES IR imagery has
shown a few stronger updrafts developing over the past 30 minutes
along the post-frontal convective line, and cooling cloud-top
temperatures are noted with pre-frontal convection across
central/eastern IA as well. While much of this activity is elevated
in nature, it remains in a conditionally favorable environment for
severe convection with MUCAPE remaining near 1500 J/kg and effective
bulk shear near 50 knots. This will continue to support some
potential for organized deep convection capable of producing
sporadic large hail and perhaps damaging winds. Latest guidance
hints that ongoing warm advection ahead of the front may support
additional thunderstorms in the coming hours - particularly from
northern MO into southern IA. If such convection emerges, the
favorably sheared environment may support some tornado threat,
though this potential is uncertain given no signs of imminent
surface-based development within the pre-frontal regime.

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0706 PM CST Fri Mar 06 2026 Valid 070100Z - 071200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS PRIMARILY FROM EASTERN OKLAHOMA AND KANSAS INTO WESTERN MISSOURI AND NORTHWEST ARKANSAS... ...SUMMARY... Scattered severe storms remain possible primarily from northeast Oklahoma into Kansas, Missouri and Iowa, with isolated severe storms extending from central Texas to Lower Michigan. Scattered hail, damaging winds, and a few tornadoes remain possible. ...Discussion... The most active area of tornado threat is currently with a cluster of storms over northeast OK. This activity may continue to evolve this evening as the low-level jet increases, and shear remains favorable into eastern KS and southwest MO. The TOP and SGF 00Z soundings continue to show wind profiles favorable for tornadic cells. To the north along the cold front, an unstable air mass remains ahead of it, although the front will quickly undercut much of the area as it continues south. However, brief supercells may occur along the boundary, with wind and tornado threat, and, elevated hail will remain possible well behind the front.

For information on northern IN into southern Lower MI, see mesoscale discussion 0154. ..Jewell.. 03/07/2026Read more
