.SHORT TERM...(This evening through Friday)
Issued at 151 PM CDT Thu Jun 15 2017

Convection is rapidly firing along an old frontal boundary and
area of convergence across north central Kansas this afternoon.
While this activity is mainly limited to a few severe storms just
south of our forecast area...continue to expect additional
development over the next several hours to potentially spread into
our southern tier of Kansas counties...across Rooks...Osborne and
eventually Mitchell counties. While some model data tries to take
this just a bit further north...latest short term solutions from
the HRRR/RAP are tracking storms more eastward...so how far north
things eventually spread is somewhat questionable. Evenso...could
not justify removing chances for thunderstorms through the early
evening hours across portions of south central Nebraska...despite
this area most likely remaining dry this evening.

Expect the threat for severe weather across our Kansas counties
to end fairly rapidly during the early evening hours as this
afternoons activity continues to push further south and east.
Models have been pretty consistent with this...and did trim pops
during the evening hours and removed them for the overnight
periods as a result. With some clouds around overnight...and a
shift in the winds to a more southerly direction...expect a
fairly mild night across the area...and did increase overnight
lows a couple of degrees in spots.

Otherwise...expect thunderstorm chances to return by Friday
afternoon as good surface heating should help to erode the CAP
across the area by late afternoon...with a nice gradient in
dewpoints likely becoming the focus for some strong to severe
thunderstorms late in the day. This dry-line is a bit further east
by peak heating time than it was yesterday at this time...but
continue to think there will be at least a chance of storms across
much of the area during the late afternoon hours...with chances
focused across our southeastern third of counties by early
evening.

.LONG TERM...(Friday night through Thursday)
Issued at 151 PM CDT Thu Jun 15 2017

Expect a fairly strong cold front to race south across the local
area on Saturday...with the timing of this front key to how much
convection we see across the area Saturday. The latest run of the
NAM already has this front to the NE/KS state line by 18Z
Saturday...which could limit severe potential across the local
area late in the day. Evenso...should see some thunderstorm activity
develop across the high plains and advect across portions of the
area during the late afternoon through evening hours.

Expect a return to near normal temps behind the aforementioned
front on Sunday...which combined with steady northerly breezes...
should make for a very nice afternoon. Thereafter...dry weather
is forecast through at least Tuesday afternoon...when a small
chance of thunderstorms returns to the local area with weak
disturbances rolling off the high plains late Tuesday and again
late Wednesday. These look like pretty iffy chances for
thunderstorms at the current time. Temperature wise...with high
pressure spreading its influence across the local area by early
next week...expect above normal temps to return next Monday
through at least Thursday of next week.

.AVIATION...(For the 00Z KGRI/KEAR TAFS through 00Z Friday)
Issued at 554 PM CDT Thu Jun 15 2017

Showers and a few thunderstorms which developed southeast of the
terminals late this afternoon have diminished and dry weather is
forecast through the night. A frontal boundary crossing the
terminals Friday afternoon/evening will bring small chances of
storms however chances do not appear great enough to insert in
TAFS with the better chances southeast of KEAR and KGRI. Wind
speeds will remain light with clouds at VFR levels.
