Area Forecast Discussion
National Weather Service Wichita KS
322 AM CDT Wed Sep 13 2017

.SHORT TERM...(Today through Friday Night)
Issued at 322 AM CDT Wed Sep 13 2017

Remnants of Irma have continued to drift NE toward the Western OH
Valley during the night. A strong upper-deck ridge, that extends
from Baja CA almost of the Wrn Dakotas, will force the remnants NE
as it gets forced in a general ely manner across the Great Plains
by a strong, positively-tilted upper-deck trof that`ll dig almost
due S from the Pacific NW to the Great Basin from today thru Fri.
The upper deck ridge should deamplify as it approaches, then
crosses, the Great Lakes Thu afternoon. The ridge, though
deamplifying, will keep us high & dry throughout these periods. A
deepening mid-level shortwave that`ll eject E from the previously
mentioned upper wave will induce weak sfc cyclogenesis across the
Western Plains. This would cause southerly flow to increase. This
warrants pressing a harder on the wind throttle, especially Thu &
Fri afternoons, from the initialization guidance.

.LONG TERM...(Saturday through Tuesday)
Issued at 322 AM CDT Wed Sep 13 2017

The "stars of the show" continue to be the western U.S. upper-deck
wave & its attendant cold front. With broad & STRONG mid-upper
deck ridging nearly covering the southeastern half of the U.S. the
upper-deck wave would still be expected to surge NE across the
Northern Plains over the weekend. The upper-deck wave may undergo
cyclogenesis as it continues to lift NE across the
Manitoba/Ontario border Sun afternoon & evening. This would cause
the attendant SE- moving cold front, progged to enter NW KS Sat
afternoon, to begin decelerating as it ventures further into KS
Sat Night. The upper- deck wave`s behavior would likely cause the
front stall in an E/W manner through KS on Sun with the front
weakening Sunday Night & Mon. With richer moisture no doubt
pooling along the decelerating front scattered thunderstorms would
be expected from Sat afternoon thru Tue. With feeble mid- upper
dynamics, the thunderstorms should behave.

.AVIATION...(For the 06Z TAFS through 06Z Wednesday night)
Issued at 1118 PM CDT Tue Sep 12 2017

VFR conditions are expected for the next 24 hours.  Expect to see
lots of high cloudiness from Irma remnants continue to swirl over the
ern half of KS.  Influence of Irma in the wind fields will slowly
wane late tonight into early on Wed, with surface winds gradually
returning to the south.
