.DISCUSSION...
Issued at 344 AM CDT THU JUN 12 2014

Thunderstorm activity off the front range of the Rockies from
yesterday has held together and crossed much of Kansas as of this
writing; with storms pushing into the far northwest corner of
Missouri before 3 AM. However, as had been previously forecast, the
low level jet feeding the broader convective band of precipitation is
pointing its nose across southern Kansas, which is taking the more
active portion of the line of storms to our south this morning into
Oklahoma. Continuing activity pushing into northwest Missouri looks
to be supported by the upper level --850mb to 700mb-- trough and
associated cold front moving east through Kansas this morning,
keeping enough juice focused in eastern Kansas to help maintain the
storms farther north despite the active southern portion of the line
intersecting the low level jet. Available CAPE early this morning is
not great, but may be sufficient to keep some of the stronger storms
percolating across northern Missouri through sunrise and into the
mid-morning hours. Have sped up the progress of the storms across our
forecast area today based on latest hi-res model runs and radar
trends. Currently, models advertise the cold front --currently nosing
into the far northwest corner of Missouri-- to sweep southeast
through the forecast area by mid-afternoon. Chance POPs that have
been kept for the afternoon are there to reflect any cast off storms
from continuing activity across southern Missouri, though this
potential is starting to look questionable.

Friday and Saturday a shortwave ridge will transit the Plains
States. This will make Friday really quite pleasant --dry with highs
in the 70s-- and Saturday --dry during the day with highs in the
80s-- really nice for early summer. However, the warm temperatures
Saturday will come as the result of warm front lifting north through
the region ahead of the next significant trough to move through the
Rockies over the weekend. This will likely provide focus for storms
Saturday night across eastern Nebraska and Iowa with activity
settling south into far eastern Kansas and northern Missouri
Saturday night. The resulting cold pool form the convection, and the
advancing cold front from the shortwave trough, will likely keep
convection going across the larger region through much of the day
Sunday. In fact, the front is expected to wallow around our section
of the country for a few days into the work week. The presents of
the nebulous boundary, and the broad troughing to our north, will
likely keep an active weather pattern in place across our section
country through at least the middle of next work week.
