.SYNOPSIS...
Issued at 232 AM CDT Sat Mar 25 2017

Larger band of showers and storms has shifted eastward into
eastern MO this morning with another area of storms developing
over northeast OK / southeast KS underneath the cutoff low
pressure system affecting the region. Stronger storms developed
further to the south over central AR / Northern LA in the vicinity
of a 50 knot low level jet and low level moist axis over the lower
Miss Valley.

Rainfall totals so far averaged around three quarters of an inch
over eastern and central portions of the forecast area, with
higher amounts around one and a half to two inches along an axis
from Gravois Mills to Bolivar to Cassville.

.SHORT TERM...(Today and tonight)
Issued at 232 AM CDT Sat Mar 25 2017

Precipitation chances and coverage have been the main focus for
the short term forecast. As the upper low moves along the
Interstate 44 corridor, cooler mid level temperatures will
destabilize the region, especially during the afternoon. Even
though drier air will be advecting in from the southwest, it looks
like there will still be enough moisture around to warrant mainly
30-50% chances for showers with isolated thunderstorms through the
afternoon.

Will taper precipitation chances from southwest to northeast
through the evening as the system exits the region.

.LONG TERM...(Sunday through Friday)
Issued at 232 AM CDT Sat Mar 25 2017

Model output has been consistent with storm system movement across
the region during the upcoming work week, so will keep
precipitation chances going pretty much as they have been for the
past few days. Late Sunday into Monday, on open upper wave and
surface trough will move across the region. Dynamics and
instability look pretty meager so don`t think we`ll see much in
the way of severe storms.

The following system looks deeper with better instability so will
need to watch this one closely, not just for severe potential but
also persistent heavy rainfall as it moves slowly eastward,
allowing a longer moisture access period.

Temperatures through much of next week will remain near to
slightly below normal with lower diurnal temperature changes due
to increased cloud cover.

.AVIATION...(For the 06Z TAFS through 06Z Saturday night)
Issued at 1124 PM CDT Fri Mar 24 2017

Storm system currently over Oklahoma is progged to move into
eastern Missouri by the end of the forecast period. Conditions
range from VFR out west in the dry slot to occasional IFR where
rain is still falling or has just ended.

With just scattered showers and isolated thunder overnight...will
expect mainly VFR with occasional MVFR ceilings. Winds have been
rather erratic during the evening and if they go light or
calm...could have issues with fog forming locally.

As the low passes through on Saturday and wrap around moisture
moves in...will see ceilings drop to MVFR in the afternoon and IFR
after sundown.
