URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 21
NWS Storm Prediction Center Norman OK
1025 PM CST Fri Mar 6 2026
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
West-Central Illinois
East-Central Missouri
* Effective this Friday night and Saturday morning from 1025 PM
until 600 AM CST.
* Primary threats include...
Scattered damaging wind gusts to 70 mph likely
Scattered large hail events to 1.5 inches in diameter possible
A tornado or two possible
SUMMARY...Squall line is slowly maturing across central Missouri.
Damaging winds may become more common with this line of storms as it
surges across east-central Missouri early this morning. A tornado or
two can not be ruled out, though damaging winds are the primary
concern.
The severe thunderstorm watch area is approximately along and 60
statute miles east and west of a line from 55 miles south southwest
of Scott Afb IL to 60 miles northwest of Saint Louis MO. For a
complete depiction of the watch see the associated watch outline
update (WOUS64 KWNS WOU1).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
REMEMBER...A Severe Thunderstorm Watch means conditions are
favorable for severe thunderstorms in and close to the watch area.
Persons in these areas should be on the lookout for threatening
weather conditions and listen for later statements and possible
warnings. Severe thunderstorms can and occasionally do produce
tornadoes.
&&
OTHER WATCH INFORMATION...CONTINUE...WW 18...WW 19...WW 20...
AVIATION...A few severe thunderstorms with hail surface and aloft to
1.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A
few cumulonimbi with maximum tops to 500. Mean storm motion vector

MD 0158 CONCERNING TORNADO WATCH 16...19... FOR NORTHEAST KANSAS INTO NORTHERN MISSOURI AND EASTERN IOWA

Mesoscale Discussion 0158
NWS Storm Prediction Center Norman OK
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.

SPC 0100Z Day 1 Outlook

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 more information about KS into IA, see mesoscale discussion
0152.
For information on northeast OK, see mesoscale discussion 0153.
For information on northern IN into southern Lower MI, see mesoscale
discussion 0154.
