Area forecast discussion, Jul 7, 2:47 PM CDT, 1 hour 42 minutes before
Area Forecast Discussion National Weather Service Wichita KS 247 PM CDT Fri Jul 7 2017 .SHORT TERM...(This evening through Sunday night) Issued at 247 PM CDT Fri Jul 7 2017 Forecast highlights...Thunderstorm chances through Saturday morning, hot and mostly dry thru the upcoming week. This afternoon-tonight...Hit-or-miss showers/thunderstorms will impact the region this afternoon, as a subtle upper level impulse approaches from the northwest, and a weak cold frontal zone moves slowly south over southern KS. Thinking widely scattered storms that can develop over southern KS will have the greatest potential to be surface-based, and thus have a higher likelihood of being strong/severe. Organized severe weather is not expected, although ample instability with weak deep layer shear could promote dime- quarter size hail, 50-60 mph winds and torrential downpours with the strongest activity. Meanwhile, severe weather appears unlikely with activity further north across central and east-central Kansas, as it is rooted around 700mb. After midnight, thunderstorm chances may increase from the west, as a loosely organized thunderstorm complex or two rolls southeast off the High Plains, amidst favorable moist/unstable low-level inflow. Most hi- resolution short-term models target primarily southern portions of central KS and south-central KS with this activity. Organized severe weather appears unlikely. Saturday-Sunday...Thinking a few morning showers/thunderstorms may linger across south-central KS Saturday. Otherwise, the rest of the day should remain dry for most areas, with highs climbing into the upper 80s to low 90s. There are some hints for a few showers/thunderstorms across mainly central and northern KS Saturday night, as afternoon Nebraska thunderstorm activity possibly moves south along eastern edge of warmer mid-level temperatures. This could linger into Sunday morning over eastern/southeast KS. Otherwise, warmer temperatures will start to creep in for Sunday, with highs reaching the upper 90s west of I-135. .LONG TERM...(Monday through Friday) Issued at 247 PM CDT Fri Jul 7 2017 Monday-Friday...Medium range model consensus supports above normal temperatures and mostly dry weather this upcoming week, as upper level high pressure builds in from the west. High temperatures will be well into the 90s, and some locations across portions of central/north-central KS reaching the low 100s per progged low-level thickness values. This will also shift the storm track north, supporting low to nil precipitation chances for most areas. If anyone is going to experience a shower or thunderstorm, it would be portions of central and northern KS Wednesday night, and again later in the week. However, the ECMWF is not nearly as optimistic with this scenario, keeping the ridge firmly in place, compared to the GFS which attempts to retrograde the ridge some by late week, resulting in increased storm chances. && .AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon) Issued at 1241 PM CDT Fri Jul 7 2017 Main concern is potential for storms throughout the period. Surface front is expected to meander near the KS-OK border for much of the forecast. Storms possible this afternoon in the vicinity of the front - and should remain just south of both KICT/KCNU. Better chances appear to be later tonight as low level jet overruns surface boundary, with best chances at KRSL/KGBD/KHUT and KICT. Slightly less chance at KSLN/KCNU. -Howerton && .PRELIMINARY POINT TEMPS/POPS...

This activity should tend to dissipate during the evening, with shower and thunderstorm chances increasing again after midnight over mainly south-central Kansas, although this activity should be below severe levels. .DAYS TWO THROUGH SEVEN...Saturday through Thursday A few showers and storms may linger across the area Saturday morning, with slight chances over central Kansas Saturday night and southeast Kansas Sunday morning.
