Area forecast discussion, Jun 2, 3:31 AM CDT, 2 hours 32 minutes before
Area Forecast Discussion
National Weather Service Wichita KS
331 AM CDT Sat Jun 2 2018

.SHORT TERM...(Today through Monday night)
Issued at 325 AM CDT Sat Jun 2 2018

Today:
Complex pattern with elevated storms going in warm air advection
and diffluent upper flow over Flint Hills and southeast KS. These
should move out of the area before daybreak. Meanwhile outflow
boundary has pushed well ahead of convection in northern KS with
precipitation dwindling on western edge where capping is stronger.
Still anticipate small pops warranted for northeastern edge of
the forecast area area. Gusty north winds anticipated behind the
front along with cooler temperatures. Winds go light and west
tonight.

Sunday-Monday:
The cooler air will linger into Sunday as surface high pressure
moves across the area. Return flow develops on Monday, with small
chances for precipitation starting early Monday morning and
continuing until daybreak Tuesday as shortwave moves through
northwest flow. ECMWF with a slightly deeper/sharper shortwave is
a bit more generous with precipitation than GFS. Temperatures
will be limited by clouds and precipitation. -Howerton

.LONG TERM...(Tuesday through Friday)
Issued at 325 AM CDT Sat Jun 2 2018

The overall trend during this period is for upper ridge to build
across the plains which suggest warming temperatures throughout
the period. Both ECMWF/GFS suggest potential for mainly nocturnal
MCSs from Wednesday night through end of the period.
Forecastability of these at this time range is difficult. While
confidence is high that storms will develop somewhere on the
plains, timing/location within the forecast area is not. Suspect
both high and low temperatures from Wed-Fri may be a bit low given
thickness, unless significant clouds and/or precipitation occurs
during the day. -Howerton

.AVIATION...(For the 06Z TAFS through 06Z Saturday night)
Issued at 1207 AM CDT Sat Jun 2 2018

LLWS of 19040kt/20050kt are likely across all areas til a cold
front surging ESE across KS causes the LLWS to weaken. As the
front approaches KSLN, (+)TSRA that'll cross NE KS may clip the
terminal. As such have introduced 3SM TSRA to KSLN from 10-12Z
when/where MVFR cigs ~1,500ft now appear possible. The passing
front would then induce a SHARP S/SW-N/NW windshift. The cold
front should reach KRSL & KGBD ~10Z, KSLN, KHUT KICT ~12Z. Prior
to the front's arrival, Sly winds sustained from 17-22kts with
gusts ~25kts are likely across C & SC KS throughout the eve. After
frontal passage, N/NW winds sustained ~22kts with gusts ~30kts
are likely across C & SC KS until early Sat afternoon when some
diminishment may occur.
