.SHORT TERM...(Today and tonight)
ISSUED AT 122 AM CDT MON JUL 7 2014

Short range models indicate an upper level shortwave exiting the
Northern Rockies and pushing east-southeast into the Northern
Plains today bringing the possibility for precip from the Dakotas
this afternoon southward into Nebraska and potentially portions of
Western Kansas tonight. As the shortwave approaches, an attendant
cold front will push southward into western Kansas this evening.
Low level moisture will continue to pool ahead of the front with
H85 dewpoints in excess of 10C across central and southwest Kansas.
Meanwhile, an upper level jet core associated with the shortwave
is projected to dive southeast across the Dakotas this afternoon
and into Nebraska toward this evening. As a result, thunderstorm
development is likely across Nebraska this afternoon with storms
migrating into northern Kansas tonight. The better chance for
storms is expected across central Kansas in the vicinity of the
I-70 corridor where proximity to the upper level jet will be
closest. Any convection is likely to be high based with the
primary threat being gusty outflow winds.

Very warm temperatures will continue today as a lee side trough
re-establishes itself by this afternoon strengthening a southerly
flow into western Kansas. This will draw slightly warmer air into
the area today pushing highs near to slightly above 100F this
afternoon. Look for lows down into the 60s(F) across west central
Kansas tonight in wake of a cold front pushing through western
Kansas overnight. Lows are still expected in the lower 70s(F)
across south central Kansas.

.LONG TERM...(Tuesday through Sunday)
ISSUED AT 335 AM CDT MON JUL 7 2014

This extended period will begin with Tuesday night.  A small short
wave in the upper atmosphere will be coming northeast from  the
southwest, with low and mid-level moisture overriding a front which
will be across New Mexico and Oklahoma.  Just slight chances for
storms at first in our southwest corner, followed by a brief period
of 30 percent Pops.  A warm front will then get pushed northeastward
late Tuesday night, and the small 20 percent thunderstorm chances
will advance northeast with the front, in the form of a NW to SE
oriented 20 to 40 mile wide band.  Precip chances will diminish
toward Wednesday morning, as the front out races the upper level
support.  Late Wednesday, a lee side trough will trigger a few
thunderstorms in our west and southwest zones, with another upper
short wave trough traveling southwest through Western Kansas
Wednesday night.  Since plenty of low level moisture will be in
place when the upper trough moves through, 30 to 40 percent chances
for thunderstorms seems appropriate, especially in our eastern zones
Wednesday night.  There could be some good rainfall amounts in the
Hays to St. John areas Wednesday night. Then the upper high pressure
ridge will build in across the western parts of the southern
plains Thursday, and cut off our chances for widespread rain. Each
afternoon a lee side trough will form, and on Friday evening and
night, as well as on both Saturday and Sunday evenings, and there
will be slight chances for thunderstorms in our west. On Monday, a
small upper low pressure wave forms in far western Kansas and
moves across Kansas. This will help aid storms form north of the
I-70 corridor Sunday night, and in our northeast and east zones
Monday.

Wednesday will start out relatively mild, with maximum temperatures
around 90 degrees.  Then the warm air advances back into Western
Kansas.  850 mb temps near 30C in our west Thursday, ranging down to
25C in our east zones will yield highs Thursday in the upper 90s
west to the lower 90s east.  Max Temperatures will be very similar
Friday through Sunday.  When that upper low moves across Monday,
plenty of clouds will be present, and highs will be considerably
lower in the mid to upper 80s.

Minimum temperatures will average in the middle 60s on Thursday and
again on Monday.  For the Friday through Sunday stretch, minimums
will be the lower to mid 70s.

.AVIATION...(For the 06Z TAFS through 06Z Monday night)
ISSUED AT 1200 AM CDT MON JUL 7 2014

VFR conditions will prevail at all TAF sites through early Monday
evening. Winds will remain light and variable through late this
morning as a weak cold front pushing southward across northwest
Kansas moves further south before washing out across southwest
Kansas. A surface low will develop across eastern Colorado this
afternoon turning winds south to southwesterly 15 to 25kt.
