...18Z Aviation Update...
.SYNOPSIS...
Issued at 238 AM CDT Wed May 17 2017
A few showers/thunderstorms were developing in an area of elevated
instability and low level jet influence over extreme southeast
Kansas into west central MO ahead of the main band of convection
still out in central KS/OK/TX. 850mb winds were howling around 45
to 55 kts across the western CWA in advance of the low pressure
still out in the high plains. Upper speed max of 100-115 kts was
streaming northeast out of TX and into OK. Focus for early morning
will be with band of convection over OK eventually making it into
the western CWA. Main focus over the 7 day period will be with the
several rounds of convection and heavy rain potential.
&&
.SHORT TERM...(Today and tonight)
Issued at 238 AM CDT Wed May 17 2017
For the early morning, will continue to see the potential of some
scattered development over the western CWA in an area of elevated
instability. In addition, the band of convection out in Oklahoma
will continue to lift northeast towards the area, with timing into
the western CWA towards sunrise. We are still expecting a fairly
quick decay of the strength and coverage of convection in our CWA
after it initially moves in as it gets away from the best
instability and sources of lift. The low, both surface and aloft
will lift to the northeast today and will be the source for
additional strong to severe storms over Iowa and northern
Missouri. A tight pressure gradient will lead to windy conditions
across the area today, with the strongest winds likely approaching
or eclipsing wind advisory criteria from late morning through the
afternoon across the northwest half of the CWA. Will be issuing a
wind advisory for this area. As for the convective potential,
after the early morning convection dissipates could see some
additional later in the day convection develop along instability
axis and possible outflow boundary across the southeast CWA where
there is a marginal risk of severe storms. Very strong shear is
expected with modest CAPE, but best synoptic scale lift will be in
the vicinity of the low pressure well to the north. The main risk
with thunderstorms later in the day would be with hail.
By tonight, any convection that may fire in the southeast CWA will
push out of the area with a generally quiet remainder of the
night.
.LONG TERM...(Thursday through Tuesday)
Issued at 238 AM CDT Wed May 17 2017
The next low will be out in the Rockies as we head into Thursday.
Instability will increase across the CWA during the day as we
remain in the warm sector south of a frontal boundary just north
of the CWA. Not much over our CWA to focus convection over the CWA
during the day other than instability. However strong to severe
convection is expected to develop by late afternoon/evening in the
plains and will likely move into our area during the night.
Depending on how much instability can develop during the day
Friday after the Thursday night/Friday morning convection, we may
have a severe risk Friday afternoon into Friday night and then
again on Saturday into Saturday night as the main front moves
through. There will be remnant boundaries across the area from the
nighttime convection to refire convection during the day should
enough instability redevelop. Several periods of heavy rain are
expected to develop from Thursday night into Sunday morning before
the system exits to the east. We are going with 1.5 to 3.5 inches
of rain across the area with the highest amounts over southeast
Kansas into western Missouri at this time with this system.
There will be a break in the convection from Sunday afternoon
through Monday night, before the next system moves in and brings
additional thunderstorm chances to the region.
While there has been some time to dry out from the previous
flooding event, water tables remain at high levels and it would
not take much heavy rain to cause additional flooding, especially
along creeks, streams, rivers and other flood prone areas.

.AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon)
Issued at 1212 PM CDT Wed May 17 2017
Very windy conditions will continue this afternoon at the
terminals, especially at JLN and SGF, where gusts could approach
or exceed 40 kt. LLWS will be possible for a time tonight as winds
begin to decrease with sunset.
Richer low level moisture will then build into the area overnight
tonight into tomorrow morning. Expect to see low stratus develop
in response, with MVFR most likely at JLN and BBG by daybreak
Thursday.

Weather hazards expected... Limited Hail risk. Limited Thunderstorm wind damage risk. Limited Lightning risk. Elevated to locally Significant Non thunderstorm wind risk. DISCUSSION... There will be a slight chance for thunderstorm development later this afternoon across south central Missouri. Should thunderstorms develop, there will be a conditional risk for marginally severe wind and hail. South winds will gust between 40 and 50 MPH over much of the region, with a few gusts to near 60 MPH across the I-49 corridor. A High Wind Warning is in effect for this area, with a Wind Advisory in effect elsewhere. Gusts will begin to diminish late this afternoon and early this evening. .DAYS TWO THROUGH SEVEN...Thursday through Tuesday. There will be a slight chance for thunderstorms during the day Thursday, with a better chance developing Thursday night as clusters of thunderstorms move northeast into the area from Kansas and Oklahoma. While these storms are expected to be diminishing in intensity as they move into the outlook area, there will be a risk for large hail to the size of quarters and 60 MPH wind gusts across western Missouri and eastern Kansas. Additional thunderstorms are expected Friday and especially Friday night as a cold front begins to move through the area. There will be a risk for severe thunderstorms during this time. In addition, one to three inches of rain will be possible, resulting in a limited risk for flooding. Thunderstorm chances will end later Saturday, before returning during the middle of next week. .SPOTTER INFORMATION STATEMENT...
