...AVIATION UPDATE...

.SHORT TERM...(Today and tonight)
Issued at 346 AM CDT Fri Jul 5 2019

Early this morning low level water vapor and profilers show mid
level trough over western Missouri with a ridge across central and
eastern Kansas. Thunderstorms in Nebraska were moving in two
different directions. Convection over central and north central
Nebraska was moving northeast on the west side of the ridge along
the 700 mb mean flow. Thunderstorms over south central Nebraska were
moving southeast along the 850 mb moisture gradient/theta-e ridge
and along the MUCAPE gradient also. RAP forecast over the next 4 to
6 hours suggests that the moisture gradient will shift to the
northeast, but still remain over parts of northeast Kansas. Other
storms that had developed from Kansas City northwest to Republic
county were dissipating within an area of subsidence within the mid
level ridge over eastern Kansas. Given precipitable water from 1.6
to near 2 inches across the area the storms will have the potential
for heavy rainfall this morning. Convective allowing models have
differed amongst solutions regarding convection this morning, but
recent runs of the HRRR and the ARW and to some extent the RAP would
move the convection across northeast Kansas closer to the Nebraska
border this morning which looks probable given latest trends on
radar at 08Z. Thermal ridge builds into central Kansas this
afternoon resulting in high temperatures reaching the lower 90s.

Late this afternoon and evening storms may develop along a frontal
boundary from southwest Kansas into south central Nebraska then move
southeast. Other storms developing across Nebraska and far northern
Kansas may build south into the low level jet tonight across central
into northeast Kansas. Storms may produce strong winds and some
large hail into the overnight hours as well as locally heavy
rainfall. Transient waves will move out into the Plains into
Saturday night, Frontal boundary could be suppressed south of the
forecast area in southern Kansas come saturday evening so will just
maintain precipitation chances of 50 percent or less.

.LONG TERM...(Saturday through Thursday)
Issued at 346 AM CDT Fri Jul 5 2019

From Sunday onward periodic chance for showers and storms will
continue as the upper high is suppressed southward and periodic mid
level waves move though the central Plains. Also models suggest a
frontal boundary may lay across the area which will aid in the
development of convection. Sunday into Monday could see some locally
heavy rainfall with an east to west baroclinic zone near the I-70
corridor and energy is forecast to move out into the Kansas Sunday
night along with an increase in the low level jet. Models differ
with the placement of the 850 mb theta-s ridge, think it will lay
across the forecast area. Once again high precipitable water values
approaching 2 inches in some areas will keep the potential for heavy
rainfall. By mid week ridging into the central Plains will bring some
drier weather for the last half of the week going into next weekend.

.AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon)
Issued at 1155 AM CDT Fri Jul 5 2019

Confidence in TS activity is low given the high variability in the
model solutions. The general expectation is for the outflow from
this morning's storms will remain across the area as the low level
jet redevelops tonight. Storms could develop along this boundary
this evening and storms off the high plains this afternoon may
track along the periphery of the upper ridge through the
overnight. So think TS are likely tonight. It's hard to be
specific about timing however. VFR conditions should prevail until
storms move in. There could be brief periods of MVFR CIGS and IFR
VSBY.
