Area Forecast Discussion
National Weather Service Goodland KS
1100 PM MDT TUE MAY 24 2016

.SHORT TERM...(Today through Thursday night)
Issued at 249 AM MDT Tue May 24 2016

Due to current ongoing storms and severe weather will wait to issue
the morning forecast until severe watch 202 is cancelled.

Southwest flow will persist across the central plains from today
through Thursday night.  A surface trough will exist over eastern
Colorado today and tonight.  The trough will move into northwest
Kansas Wednesday and Wednesday night and then align itself along the
Colorado/Kansas border Thursday night.

a shortwave is advertised to come through the flow this afternoon
and evening. The surface wind field suggests convergence to support
thunderstorm initiation across the northern fa. There is good
instability and shear to produce severe thunderstorms.  Subsidence
moves into the fa Wednesdays morning behind the exiting shortwave.
Even through there is an apparent weak disturbance in the flow
WEDNESDAY afternoon, dynamics and instability are weak so will make
pops nil until late evening when some lift is shown mainly across
the far north fa.  Subsidence follows Thursday morning so pops will
be nil.  A strong shortwave comes into the area Thursday afternoon
and night.  Good dynamics with this feature warrant higher chance
pops.

Max temperatures today through Thursday should range from the upper
70s in eastern Colorado to the lower 80s across northwest Kansas.
Min temperatures tonight should cool to the 50s.

.LONG TERM...(Wednesday night through Tuesday)
Issued at 146 PM MDT Tue May 24 2016

Going into Wednesday night...weak surface low out over the Central
Plains ahead of slow moving upper low/trough over the Rockies...will
combine with a boundary over the Kansas/Nebraska border to bring
some light rw/trw activity to mainly northern areas thru the
overnight period. By Thursday as upper trough/low begins to shift
eastward into the plains and exits the area slowly by late Friday.
some mid level ridging will allow for periods of dry conditions
going into the first half of the weekend...do expect increase in
areal coverage of rw/trw late Saturday night on through the
beginning of next week as a couple of shortwave move around the base
of approaching upper low from the Pacific NW/Northern Rockies.

The entire Tri State region will have chances for trw/rw for much of
the extended period. Lowest probability will occur on Saturday as
weak ridging occurs. Best chances for precip will occur Thursday
and Thursday night with the arrival of the enhanced dynamics of
the upper low combining with remnants of surface low/frontal
boundary. SPC currently has a slight risk for severe wx for the
entire cwa w/ focus on eastern/northern areas ahead and north of
low where best moisture/lift will occur...aided in part along the
remnants frontal boundary. Blocking h5 ridge over the eastern
portion of the country will stall the exit of this
system...allowing for wrap-around moisture to keep chances for
trw/rw into Friday before tapering off.

For temps...looking for mainly near to above normal numbers for the
extended period with mainly mid to upper 70s for daytime highs. Some
locales in eastern/southeastern zones could reach the lower 80s. The
slow passage of the upper low Thursday/Friday will provide enough
caa into nw zones to keep upper 60s for some areas. Overnight lowswill
range in the 50s with some upper 40s in ne Colorado.

.AVIATION...(For the 06Z TAFS through 06Z Wednesday night)
Issued at 1100 PM MDT Tue May 24 2016

For KGLD...vfr conditions expected through 8z with winds from the
southeast at 10 mph quickly shifting to the southwest. From 9z
through 14z stratus expected with visibilities possibly down to
2sm creating mvfr conditions with winds from the west then
northwest under 10 mph. Cigs improve to vfr by 15z with only a few
clouds at best for the rest of the taf period. Winds expected from
the north 5-10kts around 18z then back all the way around to the
east-southeast for the remainder of the taf period.

For KMCK...vfr conditions expected through 7z with cigs and vis
lowering to mvfr/ifr range through 13z with winds light from the
east. As winds switch around to the northwest cigs improve to vfr
and continue through the rest of the period. Surface winds
generally variable at speeds around 5kts or so.
