Area Forecast Discussion
National Weather Service Dodge City KS
200 PM CDT Tue Jun 6 2017

...Updated Long Term...

.SHORT TERM...(This evening through Wednesday)
Issued at 1225 PM CDT Tue Jun 6 2017

Instability is increasing across SW KS as of midday, with SPC
mesoanalysis showing ML CAPE near 1000 J/kg and lifted index of
near -4. Strong heating into the upper 80s will remove what is
left of the convective inhibition, with scattered showers and
thunderstorms developing this afternoon. Initial activity already
developing near Hays. HRRR has been very aggressive with
convective coverage this afternoon for several runs, and earlier
increased pop grids for the northern zones this afternoon. Storms
will propogate generally S/SE once formed, given the NWly flow
aloft. The threat of severe weather is marginal. Deep layer shear
is weak, but easterly upslope surface winds will help encourage
storm relative inflow and some updraft strength. Strong to
marginally severe storms are possible through this evening, with
wind gusts of 50-60 mph the primary threat. Have high confidence
that scattered thunderstorms will exist, but very low confidence
on exact coverage and placement. All models have their own ideas,
typical in nebulously forced summer-like environments. With
precipitable water near one inch, locally heavy rainfall is
likely. Pops generally favor the northern zones through tonight,
as most models are suggestive of some flavor of MCS impacting at
least the NE zones tonight. 12z GFS shows this scenario nicely,
with a thunderstorm complex affecting the Hays vicinity after 7
pm. Outside of convection, winds will trend east/NE behind a
combined cold front and outflow boundary. Lows tonight will be
held within a few degrees of 60 given a moist boundary layer and
thick cloud cover. Lower stratus clouds are expected to develop in
the moist upslope post-frontal airmass by sunrise Wednesday.

Noticeably cooler/miider on Wednesday, as 850 mb temperatures drop
back to the mid teens C. Many locations expected to hold in the
upper 70s. Boundary layer remains plentiful Wednesday, but
instability will be much weaker in the expected post-frontal
airmass. Therefore, Wednesday afternoon will be dry for most
locales. Only a slight chance mention was maintained for the
western zones late Wednesday, to account for any activity
directed into far western Kansas by the NW flow aloft.

.LONG TERM...(Wednesday night through Tuesday)
Issued at 200 PM CDT Tue Jun 6 2017

Thursday through Sunday...Heating up and drying out will be the
general theme through the weekend.

Ridge axis remains across the Four Corners on Thursday, keeping
modest NW flow locked in over Kansas. As such, will continue to
carry chance pops for showers and thunderstorms rolling off the
higher terrain Thursday evening/night. 12z ECMWF continues to
hint at nocturnal thunderstorm potential in SW KS through sunrise
Friday. Temperatures Thursday begin the warming trend, into the
80s.

Friday...Dry and warmer. Ridge axis begins phasing east, near the
Colorado/Kansas border by 7 pm. Rain chances dwindle away, with
subsidence taking over. Grids are dry (pops < 15%). The heating
trend continues, with upper 80s east to lower 90s west.

Saturday and Sunday...Hot. As flat ridge axis spreads into the
central plains, intensely hot plume at 850 mb spreads into SW KS
under weak SW flow aloft. 12z ECMWF warms 850 mb temperatures well
above 30C across the western CWA. Grids have the first 100 degrees
ratings of the season for various western/SW locales Saturday
afternoon. Just about as hot on Sunday, with little temperature
change noted at 850 mb. Kansas will be sandwiched between a 590 dm
upper ridge near Tennessee, and a strong trough in Alberta. With
the SW flow aloft, the dryline will establish. Capping will be
strong, but so will heating and instability, and there may be a
late day storm or two such as ECMWF suggests.

Cold front is expected at some point early next week, offering a
chance at a thunderstorm and cooler temperatures by Tuesday.

&&

.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 1200 PM CDT Tue Jun 6 2017

VFR will prevail the majority of the time through this TAF period.
Winds will be light and variable this afternoon along with a
developing cumulus field. High confidence in scattered showers and
thunderstorms this afternoon through tonight, but have low
confidence on exact timing and placement, and any direct impacts
on the terminals. For now, blanketed the TAFs with VCTS/VCSH/CB
through 12z Wed. TAF amendments will be required with TEMPOs as
storms approach airports. Several model solutions (including the
12z GFS) have shown consistency with a thunderstorm complex (MCS)
impacting the HYS vicinity this evening, after 00z Wed. Outflow
wind gusts as high as 50 kts will be the primary severe weather
concern. Outside of convection, winds will trend E/NE near 10 kts
overnight, as a combined cold front/outflow boundary passes south
through the terminals. Consensus of short term models is for lower
stratus cigs to arrive by 12z Wed, in the post-frontal moist
upslope. Kept cigs near 4k ft AGL (low end VFR) for now, but MVFR
cigs are possible Wednesday morning.
