Area Forecast Discussion
National Weather Service Dodge City KS
324 AM CDT Mon Jul 24 2017

...Updated short and long term discussions...

.SHORT TERM...(Today and tonight)
Issued at 324 AM CDT Mon Jul 24 2017

Upper level high pressure centered over Colorado into the Great Basin
will build east into the central and southern Plains through tonight.
The associated increase in thickness values along with plenty of
sunshine due to a fairly dry airmass over the region will result in
daytime high temperatures some 2 to 5 degrees warmer than on Sunday.
While I couldn`t totally rule out a stray thunderstorm approaching
southwest Kansas late this afternoon, think that we should remain dry
through tonight as instability is weak and no appreciable forcing
mechanisms are present across the forecast area.

.LONG TERM...(Tuesday through Sunday)
Issued at 324 AM CDT Mon Jul 24 2017

On Tuesday, a strong upper level low pressure system will move
east across southern Canada while a trailing shortwave trough
extending from the low moves east over the northern and central
Plains. This will force the lee side trough out of the eastern
slopes of the Rockies and into west central and northwest Kansas
Tuesday night along with a chance for thunderstorms to central and
west central Kansas. The upper level flow over the central High
Plains into the central Rockies becomes more northwesterly behind
this wave. This will help push a cool front south from the
northern Plains across Kansas Wednesday afternoon and evening
along with increasing chances for thunderstorms. There is some
uncertainty as to how far south the front will progress with the
GEM and GFS a little more aggressive than the ECMWF. All the models
have it south of the forecast area by Thursday evening so precipitation
chances should also be diminishing. Forecast builder POPs may be a
little high Thursday afternoon and evening.

The models tend to agree that the upper ridge will retrograde
westward into the Rockies later in the week with northwesterly
flow aloft setting up over the central High Plains. With decent
low level moisture in place across western Kansas, weak
disturbances in the northwest flow could help generate widely
scattered to scattered thunderstorms across western Kansas
especially Friday night into Saturday. This flow pattern holds on
into early next week and should help keep temperatures at more
seasonal levels in the upper 80s and lower 90s through the period.

.AVIATION...(For the 06Z TAFS through 06Z Monday night)
Issued at 1155 PM CDT Sun Jul 23 2017

High pressure building east over the central and southern Plains
will keep VFR conditions prevailing through this period. A
strengthening lee side trough over the northern High Plains will
result in an increase in southerly winds to around 10-15 knots
through the midday and afternoon hours.
