Area Forecast Discussion National Weather Service Wichita KS 647 PM CDT Wed Jul 29 2020 ...UPDATED AVIATION DISCUSSION... .SHORT TERM...(This evening through Saturday night) Issued at 257PM CDT Wed Jul 29 2020 Tonight: 24 hours later, models still showing considerable variation in 850MB flow tonight, with NAM still the most agressive with inflow, which results in well organized MCS moving quickly southeast, affecting about the southwest half of forecast area. ARW/NMM are weaker with 850MB flow, turning corfidi vectors more eastward, resulting in less organized/more widespread area of storms moving across the northern half of forecast area. HRRR/RAP are not really organized, and likely underplay western KS convection. Their solutions show more development over the area rather than storms moving into the area. Plan is to not stray too far from going forecast, and mention conditional strong/severe chances in far west. Flooding rainfall is a distinct possibility given copious low level moisture, but lack of a specific focus, inability to refine area and likely isolated locations precludes a flood watch. Thursday-Friday: Guidance continue to show relatively high chances for rain on Thursday, gradually waning from northwest to southeast on Friday. This is plausible given rich moisture and 300MB trough slowly moving across the area during the day. Precipitation chances should wane Thursday night with loss of heating and passage of trough, but a trailing trough will approach on Friday, which should enhance lift Friday-Friday night. End of precipitation Friday-Friday night will be a race between drier air filtering in and the timing of the trailing trough. On Thursday, temperatures will likely be suppressed in the north with extensive clouds and rain, but some breaks and warmer air (sans MCS) will tentatively go warmer in the south. Cooler air will keep temperatures near 80 areawide on Friday. Saturday: Will linger a chance of rain in southeast KS during the day, although this is highly dependent on timing of the second upper trough and dry air. A third upper trough will be approaching from the northwest Saturday afternoon-evening, leading to small chances of storms in central KS. -Howerton .LONG TERM...(Sunday through Wednesday) Issued at 257 PM CDT Wed Jul 29 2020 No significant changes to initialization grids. Will keep a small chance of storms in southeast KS on Sunday as upper trough swings through and a small chance for elevated storms in northwest sections Tuesday night given northwest flow and some return moisture. Otherwise dry and much cooler normal temperatures are expected. -Howerton && .AVIATION...(For the 00Z TAFS through 00Z Thursday evening) Issued at 642 PM CDT Wed Jul 29 2020 A complex of thunderstorms over northwest Kansas may grow upscale impacting much of central and south central Kansas later this evening. Other development appears likely as we move through the overnight and into the day tomorrow ahead of a shortwave trough impacting the area. A cold front will arrive late tonight/early on Thu ushering in northerly winds with continued chances for post- frontal storm activity. Very heavy rain may drive flight categories to MVFR or IFR at times with efficient rainfall anticipated. The better severe threat may remain west of our forecast area but a few strong or marginally severe storms cannot be ruled out, especially along and west of I-135 this evening. MVFR may linger into the day on Thu with some more transient low ceilings possible through the early morning hours. && .PRELIMINARY POINT TEMPS/POPS...
