Area Forecast Discussion
National Weather Service Goodland KS
317 PM MST Sat Nov 18 2017

.SHORT TERM...(This evening through Sunday)
Issued at 316 PM MST Sat Nov 18 2017

Surface high pressure moves into the southern high plains with a lee
trough deepening along the Front Range during the day on Sunday. The
upper ridge over the Rockies moves east over the plains early Sunday
with a weak short wave moving through the upper flow across the high
plains by Sunday evening.  With near surface flow turning to a more
west southwesterly downslope direction and the upper ridge moving
east of the Rockies, a dry and warmer short term period is expected.
Highs will warm to around 60 on Sunday with RH values dipping into
the teens across mainly eastern Colorado.

.LONG TERM...(Tuesday through Saturday)
Issued at 156 AM MST Sat Nov 18 2017

Expect dry conditions during the extended period as a upper level
ridge amplify over the Rockies. On Tuesday, a shortwave trough
looks to move over the ridge and across the High Plains; however,
there will not be enough moisture to work with so no precipitation
is expected. Temperatures, on the other hand, will cool down
slightly behind this trough. For the rest of the week, the ridge
continues to amplify and any shortwaves will be shunted eastward.
This will continue to produce dry conditions along with above
normal high Temperatures, lower to middle 60s, for the
Thanksgiving holiday.

The next impact to the local area looks to be next Saturday as the
models show a major front passing through the High Plains.


.AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon)
Issued at 1029 AM MST Sat Nov 18 2017

VFR conditions with clear skies are expected through the TAF
period at MCK and GLD. Gusty northwest post frontal winds this
afternoon should decrease through the afternoon into the early
evening and turn more southwest by Sunday morning.
