Area forecast discussion, Aug 27, 6:58 PM CDT, 22 minutes before

Area Forecast Discussion
National Weather Service Dodge City KS
658 PM CDT Sun Aug 27 2017

.UPDATE...
Issued at 658 PM CDT Sun Aug 27 2017

Cancelled severe thunderstorm watch 472 for most zones. Complex of
storms from Johnson City to Hugoton is organizing, and will
produce heavy rain and marginally severe hail through 8 pm.
Expect storms to exit into Oklahoma by 830 pm. Otherwise, cold
front will progress through SW KS this evening with winds trending
NE and briefly gusty. Removed all pops after midnight, and
maintained a mention of patchy fog toward Monday morning and short
term models suggest.

&&

.SHORT TERM...(This evening through Monday)
Issued at 140 PM CDT Sun Aug 27 2017

Precip chances this evening will be reliant on how quickly
conditions can recover in wake of the outflow passage from this
morning's convection. Short range models continue to show a weak
frontal boundary attendant to the upper level shortwave trough in
the Upper Midwest, moving southward across southwest and south
central Kansas early this evening. Albeit delayed due to extended
recovery time, thunderstorms are still expected to trigger in an
axis of increased forcing in the vicinity of the front as it
pushes slowly southward across the area. Although possibly further
south due to timing, the best chance for thunderstorms will be
across south central Kansas and into southern portions of southwest
Kansas. Surface dewpoints in the 60s(F) and steepening low/mid
level lapse rates will lead to MLCAPE values upward of 1500 to
2000 J/kg ahead of the boundary. Although the flow aloft will
remain fairly weak, sufficient instability combined with a
reasonable amount of shear will increase the potential for strong
to severe thunderstorms into the early evening time period. The
strongest storms will be capable of producing quarter to golf
ball size hail and damaging winds in excess of 60 mph.

Somewhat cooler air will filter southward into western Kansas
behind the boundary tonight dropping lows well down into the
60s(F) across the area. A few upper 50s(F) will be possible in
west central Kansas and in the vicinity of the I-70 corridor in
central Kansas. Expect highs only up into the 80s(F) Monday
afternoon.

.LONG TERM...(Monday night through Sunday)
Issued at 153 PM CDT Sun Aug 27 2017

A generally dry pattern is expected across much of western Kansas
through the middle part of the week as medium range models show
upper level ridging building across the Great Basin and the Four
Corners Region during the period. Drier air filtering into the high
plains and a weak northerly flow aloft will limit precip chances
across the region through at least Thursday. As for temperatures,
little change is expected to the air mass settling in across the
high plains through much of the period. Look for highs generally in
the 80s(F) to near 90F each day through the end of the week.

&&

.AVIATION...(For the 00Z TAFS through 00Z Monday evening)
Issued at 600 PM CDT Sun Aug 27 2017

Scattered convection near GCK/DDC early this evening will
propogate due south through 03z, likely with impacts at/near
LBL. Cold front passage will follow this evening, with winds
become NE and gusting near 25 kts. NE winds will diminish
quickly through midnight. Consensus of short term models and
NAM solutions indicate at least patchy fog and areas of
reduced vis in BR/FG by 12z Mon, especially at/near DDC/GCK.
Any fog burns off by 15z Mon, with VFR and good flying weather
through Monday afternoon. Expect NE winds of 5-15 kts to prevail
Monday, courtesy of surface high in eastern Nebraska.
