Severe Thunderstorm Warning 161, NWS Wichita, KS

Area Forecast Discussion
National Weather Service Wichita KS
715 AM CDT Tue May 28 2019

...Updated for Aviation Discussion...

.SHORT TERM...(Today through Thursday night)
Issued at 205 AM CDT Tue May 28 2019

A mid/upper trough over the Central Great Basin area tonight will
lift northeast across the Central Rockies before emerging over
the Central High Plains late in the day today. At the surface, an
area of low pressure over eastern Colorado will move east across
north central Kansas this afternoon. This will allow a dryline to
sharpen across central Kansas providing a focus for showers and
thunderstorms. The thermodynamic environment will be supportive
of very large hail of 2+ inches in diameter across portions of
south central KS with MUCAPE of 3000-4000+ J/KG, 0-6km bulk shear
of 50-60 knots and steep mid-lvl lapse rates. One change from the
previous forecast was to increase pops west of I-35 as the initial
updrafts are expected along the highway 14 corridor around or
shortly after 3 PM. The better large-scale forcing for ascent is
expected to remain north of the area and given the north-south
orientation of the dryline with respect to the deep layer shear
vectors, some discrete or semi-discrete supercell thunderstorms
are expected late this afternoon and into the evening hours across
south central KS. Very large hail, damaging winds and a tornado
or two will be possible before activity moves east of the area
during the late evening or early morning hours. As the previous
shift noted, anomalously high precipitable water values will be
conducive for efficient rainfall rates and possible flash flooding
concerns.

The diffuse frontal boundary is progged to lie across the southeast
corner of KS on Wed and we could see another round of storms,
especially during the afternoon & evening hours as a pv anomaly
lifts over the area on Wed afternoon-evening. Maintained some pops
weighted across southeast KS, although better chances for deep
moist convection will remain south and east of our area across
eastern OK and northwest AR.

Thu...A mid/upper trough across the Northern/Central Plains region
will slowly fill as it drifts eastward on Thu leaving a stable
post-frontal regime in place across Kansas. Drier air will advect
into the region with seasonable highs anticipated. There may be
some widely scattered storms during the peak of afternoon heating
but organized severe storms are not anticipated.

.LONG TERM...(Friday through Monday)
Issued at 205 AM CDT Tue May 28 2019

Northwest mid/upper flow will become established as we move
through the weekend and into early next week with rising
heights/increasing thickness over the Rockies and weaker mid/upper
flow across the Central Plains states. It'll be hard to rule out
some diurnal showers and storms through the period with seasonable
temperatures and continued chances for showers and storms.

&&

.AVIATION...(For the 12Z TAFS through 12Z Wednesday morning)
Issued at 709 AM CDT Tue May 28 2019

MVFR ceilings should gradually fill in this morning due to a moist
boundary layer and daytime heating. Otherwise, widely scattered
thunderstorms are likely by around mid-afternoon from generally
SLN-HUT-ICT on east, as a dryline sharpens and upper forcing
approaches from the southwest. Inserted VCTS to cover this
threat. This activity should linger well through the evening.
