AREA FORECAST DISCUSSION
National Weather Service Kansas City/Pleasant Hill MO
315 PM CDT Thu Jul 30 2020

.Discussion...
Issued at 315 PM CDT THU JUL 30 2020

A mid to upper level low paired with a couple of surface
boundaries all within the presence of ample moisture has yielded
another active weather day with showers producing moderate to
heavy rain across portions of the region. The heaviest rain is
currently falling across eastern Kansas where 1 to 3 inches of
rain has already fallen and a couple of flash flood warnings are
in effect. Moderate to heavy showers (with a few thunderstorms)
will likely persist through the afternoon and evening hours with
the focus continuing to be across eastern Kansas as the complex
slowly shifts southeastward tonight. Showers should come to an end
from north to south by Friday morning, with drier air filtering
into the region and clouds finally clearing from north to south by
late afternoon.

North northwesterly flow on the back side of the mid to upper
level trough will continue through the weekend. This will keep
temperatures well below seasonal normals. A shortwave trough and
cold front will push into the area from the north Saturday night
into Sunday, bringing chances for a few showers and storms back
into the forecast. Very pleasant weather is expected for Monday
and Tuesday as northerly flow and high pressure build into the
region with highs in the 70s and overnight lows in the upper 50s
with very low humidity. As the longwave trough finally shifts east
on Wednesday a ridge and warm air advection returns back to the
area. This should lead to a slight increase in moisture and
temperatures as well as reintroduce some slight PoP chances as we
head towards the end of next week.

Issued at 113 PM CDT THU JUL 30 2020

Showers continue across much of the region, with the heaviest
showers currently located across NW Missouri near STJ and south
and west of IXD. Showers will continue through the afternoon hours
with thunderstorms possible later this afternoon as instability
increases. All terminals will likely be impacted by at least SHRA
and perhaps TSRA between now and late evening. It is possible that
a heavy shower or storm could impact the terminals, which could
be accompanied by lowered VSBYs and CIGs. Showers and storms
should exit the region to the south by Friday morning. CIGs are
expected to lower to MVFR shortly after midnight tonight. Brief
periods of IFR CIGs will be possible, but confidence was not high
enough at this time to include in the 18z TAF. CIGs should improve
to VFR once more by mid to late Friday morning.
