MD 0744 CONCERNING SEVERE THUNDERSTORM WATCH 211... FOR NORTH-CENTRAL INTO NORTHEAST KANSAS AND SOUTH-CENTRAL INTO SOUTHEAST NEBRASKA
Mesoscale Discussion 0744
NWS Storm Prediction Center Norman OK
1015 PM CDT Sat May 16 2026
Areas affected...north-central into northeast Kansas and
south-central into southeast Nebraska
Concerning...Severe Thunderstorm Watch 211...
Valid 170315Z - 170515Z
The severe weather threat for Severe Thunderstorm Watch 211
continues.
SUMMARY...The threat for significant damaging gusts of 70-85 mph
persist this evening.
DISCUSSION...A relatively compact but intense bow echo continues to
produce significant severe gusts as it moves across northern KS and
southern NE. Multiple gusts of 70-80+ mph have been measured over
the past few hours, most recently 82 mph at Holdrege NE. Notably,
these gusts have occurred even after cool northeast surface winds
were seen at these stations. As such, at least the leading edge of
the southward-moving outflow ahead of this bow does not appear to be
mitigating severe potential.
With a 50 kt low-level jet ahead of this activity and ample
instability, the damaging wind threat is expected to persist across
WW 211, possibly reaching the MO River later this evening.

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0800 PM CDT Sat May 16 2026
Valid 170100Z - 171200Z
...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS NORTHERN
KANSAS AND SOUTHERN NEBRASKA...
...SUMMARY...
Severe thunderstorms capable of producing large hail,
severe/damaging winds (some 75+ mph), and a couple tornadoes remain
possible tonight, especially across southern Nebraska and northern
Kansas.
...01z Update - Central Plains/Missouri Valley...
Primary scenario this evening will be an upscale-growing/organizing
cluster of storms across northern Kansas and southern Nebraska. A
bit more spatial room has been given (southward adjusted) across
northern Kansas (mostly north of I-70) for what may still be a
post-01z increasing damaging wind potential, including
significant-caliber wind gusts across northern Kansas and far
southern Nebraska, aside from a lingering broad regional potential
for some large hail as well. Measured 85 mph gusts have recently
been reported near Colby, Kansas.
