.SHORT TERM...(Today and tonight)
Issued at 333 AM CDT Fri Apr 20 2018
A strong upper level disturbance was approaching from the west.
This system will be coming out into the plains in two major
pieces. The first vorticity lobe will rotate across the high
plains today and then the next system is expected to move across
the southern plains on Saturday. Most of our rain will be with the
lead system, but south central Kansas will also see some rain
with the second system. Low level moisture inflow into this system
is marginal since low level trajectories are from the east and
southeast around cool high pressure system instead of out of the
Gulf. Lapse rates do not support much in the way of thunderstorm
activity; but a couple of rumbles can`t be ruled our along the
Oklahoma state line. Upped rain chances to 100% much of the area
for this afternoon and evening. Widespread rain amounts to a half
inch can be expected by Saturday, with locally higher amounts over
three quarters of an inch in west central and south central
Kansas. Highs today will be held down by clouds and afternoon rain
in far western Kansas. Highs in Dodge City will be in the early
afternoon before the rain starts. The warmest readings will be in
central and south central Kansas with highs in the lower 60s
there. Temperatures tonight will be held up by cloud cover with
mainly lower 40s for lows.

through the TAF sites between 19 and 00z and then persisting
through the period. CIGS will gradually lower from VFR to low MVFR
