.UPDATE...
Issued at 525 PM CDT Fri Jul 1 2016

Updated rainfall/thunderstorm coverage in the grids, along with
QPF/wx/sky grids, to align with radar/satellite trends, the
neighboring WFOs, and the HRRR forecasts through tonight. Radar
trends show strong to severe convection west of Lamar and
approaching Elkhart. In the short term, there will be a limited
threat of severe weather across far SW Kansas, where the
instability axis resides, with ML CAPE near 2000 J/kg. Later
tonight, agree with previous forecaster that another MCS will
track mainly across the northern zones. 18z GFS and HRRR strongly
suggest this evolution, as such increased pops into the
likely/definite category north of Dodge City. Primary threat
through tonight will be excessive rainfall and localized flooding,
with an exceptionally moist atmosphere with precipitable water
ranging from 1.6 inches NW to 1.8 inches SE as of 5 pm mesoanalysis.
Will need to consider a flash flood watch over the next few hours.

.SHORT TERM...(This evening through Saturday)
Issued at 249 PM CDT Fri Jul 1 2016

A stronger upper level shortwave trough will move from Four Corners
region and into western Kansas tonight. Another MCS (Mesoscale
Convective Complex) will likely move out of Colorado and and across
much of western Kansas tonight with several upper level waves.
Current models however forecast the best QPF and best heavy rain
chances north of Dodge City with the area from around Syracuse to
near Garden City and LaCrosse and north. Will graduate rainfall
chances with that in mind. Severe chances look minimal tonight with
maybe some small hail and strong winds to 40 to 50 mph. Very heavy
rainfall is expected wherever the MCS tracks with precipitable water
values from 1.5 to near 2 inches. Lows tonight will range in the mid
to upper 60s.

For Saturday, the strong shortwave will continue to move across
western Kansas with an attendant cold front. The cold front is
forecast to be near Hays to Dodge City and Meade by mid afternoon
with the best chances for storms near and east of the front.
Strong to severe storms are possible mainly along and east of the
cold front with 2000 to 3000 J/kg CAPE and strong mid level
shear. Highs will be around 90 east of the front and low to mid
80s west.

.LONG TERM...(Saturday night through Friday)
Issued at 307 PM CDT Fri Jul 1 2016

For Saturday night, a cold front will continue to move east into
central Kansas with lingering strong to severe thunderstorms mainly
east of Dodge City into parts of south central Kansas.

Then for Sunday into next Friday, a mainly dry period is forecast
with a warming trend. Highs warm from the 80s Sunday and around 90
for Monday, the 4th of July, into the mid to upper 90s from
Tuesday into next Friday, as warmer upper level ridging builds
into the Central Plains. Overnight lows will gradually warm also
from 60s into the 70s.

.AVIATION...(For the 00Z TAFS through 00Z Saturday evening)
Issued at 600 PM CDT Fri Jul 1 2016

Scattered, mainly nocturnal, convection will continue to impact
aviation and be the main challenge in the 00z TAFs. Highest
confidence that convective TEMPO groups will be needed at GCK
later this evening and HYS overnight. Model consensus is for
another MCS complex to track across western Kansas tonight, with
TAF amendments likely. Severe risk will be limited to outflow wind
gusts to near 50 kts. Excessively heavy rain is likely from any
storm, with brief IFR likely. Consensus of short term models
places the lowest (MVFR/IFR) stratus cigs near HYS beginning
around 09z Sat. SE winds will persist outside of convection.
Another brief break of dry weather around 15-18z Sat, before
scattered TSRA redevelop by 21z Sat.
