SPC MD 761MD 0761 CONCERNING TORNADO WATCH 213...214... FOR PORTIONS OF EASTERN NEBRASKA INTO NORTHERN KANSAS AND WESTERN IOWA 
Mesoscale Discussion 0761
NWS Storm Prediction Center Norman OK
0653 PM CDT Sun May 17 2026
Areas affected...portions of eastern Nebraska into northern Kansas
and western Iowa
Concerning...Tornado Watch 213...214...
Valid 172353Z - 180100Z
The severe weather threat for Tornado Watch 213, 214 continues.
SUMMARY...Severe wind and hail remain a concern with ongoing storms
over eastern NE into western IA and northern KS. Focused corridors
of severe wind, with isolated QLCS tornadoes, may accompany mature
bowing segments.
DISCUSSION...The cold front continues to surge southward and merge
with the dryline, which may be at least partially contributing to
the rapid upscale growth of ongoing multicells and supercells into
line segments. Should this trend continue, then severe wind will
become the main threat in a couple of hours, with a secondary risk
of hail and isolated QLCS tornadoes. Bowing segments may be capable
of producing focused corridors of 50+ kt gusts, with some exceeding
65 kts in magnitude. QLCS tornadoes are also most likely with the
bowing segments.
Supercell tornado potential seems more conditional given the
prominent mixed/linear storm modes. One storm in Thayer County, NE
is attempting to maintain supercell structure and currently contains
a tornado. Given strong instability and vertical wind shear in
place, any discrete supercell that can sustain itself will have a
conditional potential to produce a strong tornado.

SPC MD 762MD 0762 CONCERNING SEVERE POTENTIAL...TORNADO WATCH LIKELY FOR PORTIONS OF CENTRAL AND SOUTHERN IOWA 
Mesoscale Discussion 0762
NWS Storm Prediction Center Norman OK
0740 PM CDT Sun May 17 2026
Areas affected...portions of central and southern Iowa
Concerning...Severe potential...Tornado Watch likely
Valid 180040Z - 180145Z
Probability of Watch Issuance...80 percent
SUMMARY...A severe threat will accompany an approaching QLCS. Severe
wind and hail will be the most predominant threats, but isolated
line-embedded tornadoes may also occur. A Tornado Watch will be
needed soon to address the impending threat.
DISCUSSION...An elongated persistent convective system with a
history of severe wind and hail is approaching the NE/IA border, and
is poised to exit the ongoing Tornado Watches in the next few hours
as the line advances further into IA. Across IA, which resides south
of the warm front and ahead of a surface trough, a highly buoyant
and sheared warm sector exists. Roughly 80 F/70 F surface
temperatures/dewpoints overspread by 8+ C/km mid-level lapse rates
is contributing up to 3000 J/kg MLCAPE per 00Z mesoanalysis.
Meanwhile, mesoanalysis also shows a LLJ increasing to 40 kts over
IA. These analyses roughly matches the 00Z OAX observed sounding,
which shows near 8 C/km mid-level lapse rates and nearly 3000 J/kg
MLCAPE, as well as a curved low-level hodograph with over 300 m2/s2
effective SRH.
Given the aforementioned environment, the current thinking is that a
QLCS will progress across central IA, accompanied by a severe
wind/hail threat. Isolated QLCS tornadoes are possible with any
mesovortices that materialize, and focused corridors of severe wind
will accompany any bowing segments. A couple of gusts over 75 mph
cannot be ruled out. A Tornado Watch will be needed in the next
couple of hours.

SPC Tornado Watch 214WW 214 TORNADO IA KS NE 172010Z - 180400Z
URGENT - IMMEDIATE BROADCAST REQUESTED
Tornado Watch Number 214
NWS Storm Prediction Center Norman OK
310 PM CDT Sun May 17 2026
The NWS Storm Prediction Center has issued a
* Tornado Watch for portions of
Far Southwest Iowa
North-Central and Northeast Kansas
Southeast Nebraska
* Effective this Sunday afternoon and evening from 310 PM until
1100 PM CDT.
* Primary threats include...
A few tornadoes likely with a couple intense tornadoes possible
Scattered damaging winds likely with isolated significant gusts
to 75 mph possible
Scattered large hail likely with isolated very large hail events
to 3 inches in diameter possible
SUMMARY...The airmass ahead of the approaching cold front from
southeast Nebraska into north-central/northeast Kansas continues to
destabilize amid strong heating and low-level moisture advection.
Discrete thunderstorm development is possible in the warm sector
ahead of this cold front, with the environmental conditions
supportive of supercells capable of all hazards, including very
large hail to 3" in diameter and strong tornadoes. Thunderstorm
development is possible along the front as well, with large hail and
damaging gusts as the primary hazards with these storms.
The tornado watch area is approximately along and 95 statute miles
east and west of a line from 10 miles north northeast of Columbus NE
to 25 miles south of Concordia KS. For a complete depiction of the
watch see the associated watch outline update (WOUS64 KWNS WOU4).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
REMEMBER...A Tornado Watch means conditions are favorable for
tornadoes and 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.
&&
OTHER WATCH INFORMATION...CONTINUE...WW 213...
AVIATION...Tornadoes and a few severe thunderstorms with hail
surface and aloft to 3 inches. Extreme turbulence and surface wind
gusts to 65 knots. A few cumulonimbi with maximum tops to 550. Mean
storm motion vector 24035.

shear strengthens this evening.
