Heat Advisory 7, NWS Wichita, KS

Area Forecast Discussion
National Weather Service Wichita KS
1225 PM CDT Sat Aug 19 2017

.SHORT TERM...(Today through Monday Night)
Issued at 335 AM CDT Sat Aug 19 2017

Today:
Mostly sunny & hot weather is slated for all areas as a broad but
strong mid-upper ridge covers the Great Plains.

Tonight:
A few thunderstorms are scheduled to arrive primarily central KS
late tonight then spread east across about the northern half of KS
thru Sun morning as a weak & compact mid-level shortwave scoots
east along the Nebraska/KS border. Lift is feeble, as such most if
not all of the thunderstorms should behave.

Sunday & Sunday Night:
With STRONG mid-upper high covering the southeastern fourth of the
U.S. a broad mid-level trof covering most of the western U.S. will
remain nearly stationary. Such feeble dynamics would keep thunder-
storms in check on Sun but come Sunday night a subtle impulse will
eject NE from the southwestern plains that may reach western KS.
There may be enough lift to produce isolated thunderstorms late
Sunday Night.

Mon & Mon Night:
Thunderstorm potential will begin to increase Mon afternoon then
increase considerably Mon night as a strengthening mid-upper trof
ventures SE from the Manitoba/Ontario border into the Northern
Plains. This would bring a cold front SE that should reach Central
KS late Mon night.

.LONG TERM...(Tuesday through Friday)
Issued at 335 AM CDT Sat Aug 19 2017

Tue & Tue Night:
The mid-upper trof moving SE from the Northern Plains to generally
the Ohio Valley should provide enough of a kick to force the cold
front to the Red River early Wed morning. As such, thunderstorms
would likewise shift S/SE & would likely be confined to southern
KS early Tue morning.

Wed-Fri:
Cooler weather will spread across KS as high pressure spreads SE
from the Northern Plains to the Great Lakes. A much drier airmass
would keep any chance of thunderstorms in check.

.AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon)
Issued at 1220 PM CDT Sat Aug 19 2017

VFR conditions at all locations with this forecast package. High
pressure will slide east ahead of an approaching low. This will
pack down the gradients beginning this evening and on Sunday.
Hence, I have brought back gusty southerly winds. I have added
VCTS to KRSL and KSLN as an upper pva pocket slides out of NE and
into NC KS. This should usher shra and tsra into the vicinity. I
don't anticipate much converage. This will also bring in a thicker
mid and uppler level cloud deck.
