Area Forecast Discussion National Weather Service Wichita KS 330 PM CDT Mon Sep 18 2017 .SHORT TERM...(This evening through Wednesday) Issued at 329 PM CDT Mon Sep 18 2017 Water vapor imagery shows a shortwave exiting eastern KS and heading into the Mid Mississippi Valley. Meanwhile, more robust upper energy will dig over the Pacific NW into the the Northern Intermountain. Main question for storm chances overnight will how much subsidence behind the departing wave will lower chances for storms. Current thinking is that there is still a small chance for a storm this evening and tonight due to increasing mid level moisture transport and mid level theta-e advection due to a fairly decent mid level baroclinic zone. In addition, capping will be minimal once you get above 850mb. So while confidence is high we are not looking at widespread or even scattered activity tonight, hard to rule out a couple storms. Strong return flow will setup over the Plains on Tue as lee troughing strengthens in response to shortwave continuing to dig over the northwest CONUS. South winds will be close to advisory criteria Tue afternoon with sustained speeds in the 25 to 30 mph range. However, confidence isn't high enough to run with one at this point, mainly because even though we mix high, wind speeds at the top of the mixing layer aren't that impressive. Bigger story Tue afternoon maybe the fire danger potential, which looks to be very high for areas along and west of I-135. See fire weather section below for additional details. Pacific cold front is expected to slide into the area on Wed which will bring slightly cooler air to much of the area, but still with highs a degree or two above normal. Airmass looks fairly capped, so not expecting storms to develop along along the front Wed afternoon. Additional upper energy will track out of northern Pacific and reinforce the trough over the northwest CONUS. This will allow return flow to once again increase, pumping up afternoon highs Wed. .LONG TERM...(Thursday through Monday) Issued at 329 PM CDT Mon Sep 18 2017 Both ECMWF and GFS agree on a sharp upper trough anchored over the western CONUS to start this period, which will keep return flow and above normal temps in place over the Plains. Through Fri, precip chances are expected to remain north of the forecast area with storm chances increasing slowly from northwest to southeast Sat through Mon. Our central KS counties look to have better rain chances this weekend due to being closer to the front. && .AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon) Issued at 1239 PM CDT Mon Sep 18 2017 VFR conditions expected to prevail thru the forecast valid period. Clearing will continue to progress eastward from central to eastern Kansas this afternoon, although some cumulus are expected to develop with diurnal heating. Isolated convection is possible this evening and tonight, though too remote to mention in the terminals for now. South winds will increase markedly during Tuesday morning, becoming strong and gusty across central Kansas just beyond the forecast valid time. KED && .FIRE WEATHER... Issued at 329 PM CDT Mon Sep 18 2017 Grassland fire danger will be elevated into the very high category Tuesday afternoon for areas along and especially west o I-135. South winds will increase Tue afternoon to sustained speeds around 25-30 mph with gusts around 35 mph. Areas west of I-135 will have the best chance for some of the higher gusts. Lowest RH's Tue afternoon will be around 20% for areas along and west of highway 14 with around 35-40% for areas along I-135. The only two counties we considered for a red flag warning was Russell and Barton, but after talking to DDC and with marginal GFDI values, will hold off for now. && .PRELIMINARY POINT TEMPS/POPS...

Hail to quarter size and 60 mph winds will be possible. Meanwhile, a couple storms will be possible tonight, mainly along and east of a Salina to Lyons line. If a storm can develop, it will have a chance to produce small hail and gusty winds. .DAYS TWO THROUGH SEVEN...Tuesday through Sunday Tuesday, strong south winds and low relative humidities will result in very high grassland fire danger for areas generally along and west of Interstate 135. Outdoor burning is strongly discouraged Tuesday. Wednesday, there is a chance for some isolated thunderstorms east of I-35 during the evening hours. Strong storms can't be ruled out with this activity. Chances for thunderstorms should gradually increase from the west through the weekend and into early next week. Current indications suggest the potential for multiple rounds of storms, with an accompanying risk of severe weather, heavy rain and flooding. There remains quite a bit of uncertainty, so stay tuned. .SPOTTER INFORMATION STATEMENT... Spotter activation is not anticipated this tonight. && For a graphical version of this information, see our webpage at: http://weather.gov/wichita/hwo/ Lawson
