Area Forecast Discussion
National Weather Service Dodge City KS
710 PM CDT Mon May 14 2018

.UPDATE...
Issued at 710 PM CDT Mon May 14 2018

It has been a quiet evening across SW KS with thunderstorms so far
avoiding the SW KS region. This is expected to change over the
next 2-3 hours, as severe thunderstorms approach from the NW,
storms potentially arrive from Oklahoma, and scattered
thunderstorms develop areawide by midnight. Atmosphere over SW KS
is moderately unstable (MLCAPE 1500 J/kg) and sufficiently sheared
(40-50 kts bulk shear) to support severe thunderstorms. The severe
thunderstorm near Sharon Springs has a long history of damaging
wind and hail, and shows no signs of weakening as it approaches the
NW CWA zones. Tracking off of radar, the storm wilbe impacting the
Scott county vicinity by 9 pm. Only minor changes to pops for now,
but should HRRR/NAM evolution trends verify, will need to ramp up to
likely pops soon.

&&

.SHORT TERM...(This afternoon through Tuesday)
Issued at 1200 PM CDT Mon May 14 2018

Frontal boundary that has separated SW KS for days slipped
southward again overnight, with a stable boundary layer and areas
of stratus/fog behind it. Just like yesterday, stratus will
continue to burn off this afternoon. After a decent push
southward overnight/this morning, the boundary has pulled up
stationary again as of midday, essentially biscecting the
SE CWA. SE of this boundary, instability is again mounting rapidly
with MLCAPE already near 3000 J/kg near Medicine Lodge as of
11 AM. Most models develop convection along this convergent axis
over/near Barber county by 4 pm. Vast majority of activity is
expected to remain in Wichita's and Norman's jurisdiction today,
but the environment will again support large damaging hail from
any supercell so will need the monitor the SE zones closely into
this evening. Bulk effective shear is a bit improved in this
initiation area compared to yesterday, in the 30-35 kt range.
Also, have noted once again that 12z NAM spikes 0-1 km EHI in this
zone for several hours centered on 00z (7 pm). So, once again any
discrete supercells that avoid destructive interference will be
capable of large damaging hail as the primary threat. Surface-
based activity will be hard to come by, once again limiting the
tornado threat.

After 7 pm, additional shower/thunderstorm activity is expected to
spread further west deeper into SW KS, in response to weak
shortwaves isentropically lifting moisture over the stalled
frontal boundary. Severe weather is not expected from this
activity, with NAM progging elevated CAPE on the order of only
500-1000 J/kg. Kept scattered pops in the grids; hopefully this
will be some beneficial rainfall for areas that have missed out
recently (eg, Dodge City). Otherwise, light moist north winds will
again spread stratus and/or fog southward after midnight, with
temperatures Tuesday morning mainly in the 50s.

Tuesday...A light NE breeze will be maintained, which will hold
temperatures near normal for mid May, in the mid to upper 70s.
Rainfall opportunities will be limited, with most of the forcing
and instability south of SW KS. Kept some pops along the southern
zones, but this is likely overdone. Most locations Tuesday will be
dry.

.LONG TERM...(Tuesday night through Monday)
Issued at 200 PM CDT Mon May 14 2018

Closed low enters northern California on Wednesday, which forces
upstream ridging over the Rockies and high plains. Temperatures
will warm accordingly into the low to mid 80s. Pop grids from the
forecast builder model blend look overdone, with little forcing
present. 12z ECMWF's representation of more isolated convection
across the western zones appears more realistic.

Closed 566 dm upper low cruises into Nevada on Thursday. Ridge
axis crosses SW KS Thursday morning, phasing east into central
Kansas by afternoon. As such, weak SW flow aloft will resume by
late day, along with associated stronger lee troughing in eastern
Colorado. More isolated late day storms are probable along the lee
trough convergence axis. Coverage will be very limited. The
warming trend will continue, into the upper 80s.

The potential for severe weather is increasing on Friday. 12z
ECMWF displays a much more classic May synoptic setup for dryline
convection Friday afternoon. 566 dm upper low near Salt Lake City
at sunrise Friday ejects NE in a weakening state into Wyoming by
evening. Jet streaks and shortwaves eminating from the base of
this trough will interact with an established dry line, with ECMWF
QPF painting storms along the length of the dryline, from western
Nebraska all the way to Big Bend National Park Texas. ECMWF 0-1 km
EHI progs show severe weather is probable across Nebraska/Kansas
Friday afternoon/evening. Medium range models show moisture return
will be at least capable of supporting higher end severe, with
surface dewpoints in the mid 60s across the eastern CWA.
Temperatures will peak on Friday, at least into the lower 90s,
with the hottest temperatures west of the dryline. Current
forecast is almost certainly not hot enough, with MEX guidance
already suggesting mid 90s. South/SE winds will also increase
strongly Friday afternoon, given ECMWF's depiction of a 994 mb
surface low in Baca county Colorado.

Cold front passage expected Friday night and Saturday, followed by
north winds and cooler temperatures. Afternoon max temperatures
will fall back to the 70s Saturday and Sunday.

&&

.AVIATION...(For the 00Z TAFS through 00Z Tuesday evening)
Issued at 510 PM CDT Mon May 14 2018

Another complicated TAF forecast package with convection and IFR
cigs/vis issues. VFR will prevail for the next few hours, as
thunderstorms remain south, east and west of the terminals.
Short term models (including HRRR and 18z NAM) show convection
currently in Colorado spreading into SW KS this evening. Included
VCTS/CB given uncertainty, but a bow echo may produce locally
strong/severe winds to 50 kts. TAF amendments are likely. Other
convection is either expected to move in from Oklahoma, or develop
after midnight in a scattered fashion. Stationary frontal boundary
draped south of DDC will get another nudge southward through
Tuesday morning, with high confidence that stratus/fog will fill
back into the airports through 12z Tue.
