AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE DODGE CITY KS
1222 AM CDT Wed Aug 20 2014

...Updated for Aviation...

.SHORT TERM...(This evening through Wednesday)
ISSUED AT 229 PM CDT TUE AUG 19 2014

There is an upper level high pressure ridge working east across the
plains, helping to squash the convection potential this evening.
There have been some mid and high level cumulus-type clouds building
up, they get suppressed downward about as soon as they bubble up.
Will keep a dry forecast going tonight, with winds early from the
south at 12g20kt.  After sundown, or about 03z, winds should settle
from the southeast at 09-12kt.  There is a surface trough near the
Colorado border, and it will only move east and west just a little
over the next 2 days.  I did not change the forecast minimum temps
tonight, as near 70F degrees in our west and around 74F degrees in
our southeast near Kiowa seems reasonable.

On Wednesday, we will have a northwest flow aloft over western
Kansas, with a low pressure trough again near the Kansas/Colorado
border.  There will be some layered moisture riding up through
eastern New Mexico and eastern Colorado, but the south flow over our
CWA should result in some mixing out at the lowest layers and the
dew points drying out a little.  Our far west counties could see dew
points dip into the 40s, the lowest they would have been in quite
awhile.  Surface temperatures should soar into the upper 90s at most
locations, and winds will be pretty windy from the south at 25 mph
gusting to 35 mph.

.LONG TERM...(Wednesday night through Tuesday)
ISSUED AT 300 PM CDT TUE AUG 19 2014

Wednesday night/Thursday:

Somewhat problematic pops for Wednesday evening as confidence in seeing
thunderstorm development is low and activity should remain isolated.
NAM has a few storms developing Wednesday evening across northwest Kansas,
which may drift close to my northwestern zones. Have slight pops here,
but generally shifted the line farther west. Otherwise, the rest of
the area will remain precipitation-free with lows in the 70s. Isolated
convection will be possible again across western Kansas Thursday evening,
near the sfc trough, but a rather dry atmosphere and weak forcing will
limit overall convective potential. Kept pops in the slight range.
Otherwise, highs in the upper 90s to near 100F still looks prudent at
this time.

Friday and beyond:

The rest of the forecast is fairly ho-hum with hot weather and slight
chances for thunderstorms during the afternoons and evenings. An upper
level ridge will remain southeast of the forecast area, while a trough
moves across the northern Rockies through next weekend. Again, there
may be isolated storms and temperatures will be near to slightly above
normal. Change is still possible by Sunday into Monday, when a fairly
strong cold front moves across the Central Plains. With this front stalling
around the region, there may be continued thunderstorm chances and maximums
cooling down. The more seasonal conditions look to continue through
the rest of the forecast period.

.AVIATION...(For the 06Z TAFS through 06Z Wednesday night)
ISSUED AT 1217 AM CDT WED AUG 20 2014

A trough of low pressure will again deepen in the lee of the
Rockies today with light south winds becoming south 15-25kt in the
afternoon. Only some high level cirrus clouds are expected with
VFR conditions prevailing. There may be an outside chance for a
thunderstorm near KHYS tonight.
