Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0654 PM CST Mon Mar 06 2017

Valid 070100Z - 071200Z

...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FROM EASTERN
PORTIONS OF KANSAS AND OKLAHOMA INTO THE MIDDLE MISSISSIPPI VALLEY
REGION...

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM EASTERN
KANSAS AND OKLAHOMA THROUGH A PORTION OF THE LOWER THROUGH UPPER
MISSISSIPPI VALLEY...

...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM EASTERN
KANSAS AND OKLAHOMA THROUGH A LARGE PART OF THE MISSISSIPPI
VALLEY...

...SUMMARY...
Severe storms are expected until mid evening over the upper
Mississippi Valley area. Other severe storms will persist into the
overnight across the middle to lower Mississippi Valley region and a
portion of eastern Kansas into Oklahoma. Damaging wind, large hail
and a few tornadoes are expected, but the dominant threat should
transition to damaging wind later tonight.

...Eastern Kansas and Oklahoma into the Mississippi Valley region...


Squall line currently western WI through IA into northeast KS will
continue to pose a threat for severe weather as it continues east
tonight including large hail, damaging wind and a few tornadoes.
Instability corridor is narrow over the upper MS Valley region, and
storms will likely weaken toward mid evening as they move farther
into WI.

Farther south, the severe threat will likely persist into the
overnight and early morning. Storms should continue to backbuild
along southeastward-advancing cold front through the remainder of
eastern KS into eastern OK. A strong mid-level jet rotating through
the base of a northeastward-ejecting upper trough coupled with an
intensifying southwesterly low-level jet is contributing to very
favorable vertical shear profiles and large 0-1 km hodographs
supportive of organized storms. Embedded supercell and bowing
structures are likely as the line develops through eastern Kansas
and Oklahoma and eventually into MO and AR, and this activity will
pose a threat for mainly damaging wind and large hail, with a few
tornadoes also possible. Additional more discrete storms may develop
within the low-level confluent flow regime across northern AR into
MO this evening. Some of these storms may evolve into supercells
with a threat for large hail and a few tornadoes.

29 reported tornadoes yesterday, 253 wind reports, 93 hail reports; Total 375 severe wx reports. Most tornadoes in March since 3/2 2012

Possible tornado destroys Greasy building, damages homes.

ADAIR COUNTY, Okla. (KTUL) — Several buildings were damaged and at least one was destroyed after storms and a possible tornado ripped through the small town of Greasy last night.
The storm appears to have leveled a community building. Police tell us the building is used mainly for events and is not occupied every day.
Police say crews responded to a report of a gas leak in the town, but the incident involved a propane tank and it's not clear exactly what happened. Roads were closed while crews responded to the incident.
