Area forecast discussion, Apr 10, 7:26 PM CDT, 3 hours 17 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE Tulsa OK
726 PM CDT SUN APR 10 2016

.DISCUSSION...
Storms have erupted over northeast Oklahoma this evening from
Pawnee county into northern Washington county. This is in advance
of the Cold front that is currently across northwest Oklahoma into
southeast Kansas. This is in area where the cap has eroded with
cape in the 2000 J/KG range. These storms will likely produce large
hail to the size of limes and wind gusts to around 70 mph. There is
also the potential for these storms to gain some rotation. Additional
storms are expected to move into the region from western Oklahoma later
this evening and from the northwest along the cold front. In addition
to the severe potential, heavy rain is possible with localized flooding.
