.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 218 AM CDT WED AUG 5 2015
The main forecast challenge for today is areas of dense fog early
this morning and how far west and south into southwestern Kansas.
RAP model in good agreement with NAM supporting areas of dense fog
and low stratus into around 14-15Z this morning from Scott City to
Medicine Lodge and east including Dodge City. Higher dewpoints are
forecast to come into the area as east to northeasterly winds
develop as surface low pressure moves into the Texas Panhandle area.
Will probably need to issue a Dense Fog Advisory shortly. After
areas of dense fog and stratus burns off by mid morning, skies
should be mostly sunny with easterly winds around 8 to 15 mph. Highs
today will range from the mid 90s far west near Liberal to Syracuse
and west, with low 90s to upper 80s elsewhere. The coolest in parts
of north central Kansas.
For tonight, moist easterly upslope winds continue at around 10 mph
with possibly more areas of dense fog or stratus developing after
midnight into the early morning. Lows will be in the upper 60s to
around 70 at Medicine Lodge.
.LONG TERM...(Wednesday NIGHT THROUGH Tuesday)
ISSUED AT 305 PM CDT TUE AUG 4 2015
There is an outside chance for thunderstorms across central Kansas
late Thursday as medium range models indicate an upper level
shortwave tracks eastward across the northern plains early in the
time period. Although the flow aloft will remain fairly weak above
much of southwest and south central Kansas, all models show a
modest upper level jet core streaming eastward eastward across
Nebraska and clipping portions of northern Kansas. As low/mid
level lapse rates steepen in conjunction with the arrival of a
cold front attendant to the shortwave to our north, a few isolated
thunderstorms could develop across central Kansas in the vicinity
of the I-70 corridor during the late Thursday afternoon/early
evening time frame. Otherwise, drier conditions are likely across
central and southwest Kansas through Friday as upper level ridging
across the desert southwest and southern Rockies moves east into
the Western High Plains. Chances for precip may return Friday
night as the GFS and ECMWF both show a weak upper level shortwave
ejecting out of the Colorado Rockies into the high plains of
northeast Colorado, southwest Nebraska, and northwest Kansas.
Plenty of uncertainty remains as to the track and timing of this
system but the best chance for thunderstorms looks to be across
more northern portions of the forecast area, to include west
central and central Kansas, if at all.
Seasonal temperatures can be expected Thursday as a low level
southerly flow re-establishes itself across western Kansas ahead of
an approaching cold front. Widespread 90s(F) are expected for highs
Thursday afternoon. Highs Friday will be dependent on how far south
the frontal boundary mentioned earlier reaches before stalling out.
Regardless, highs should reach the 90s(F) for the most part,
especially further south along the Oklahoma border. Highs could
reach near 100F in some locations Saturday as the aforementioned
upper level ridging moves into the Western High Plains to finish
out the week.
.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z Wednesday NIGHT)
ISSUED AT 1118 PM CDT TUE AUG 4 2015
As a surface low pressure trough in eastern Colorado moves south,
light southeast moist upslope winds become light easterly to
light and variable by dawn. Some stratus and light fog may develop
especially at KHYS after 09z, and is possible in the KDDC and KGCK
areas also, but not confident enough to add to TAF forecast attm.
Expect VFR conditions with some IFR/MVFR cigs/vis at KHYS through
