019 FXUS63 KTOP 021727 AFDTOP Area Forecast Discussion National Weather Service Topeka KS 1227 PM CDT Wed Jul 2 2025 .KEY MESSAGES... - Seasonably warm with increasing humidity into the holiday weekend. - Chances for storms return for the 4th of July and linger into early next week. Highest chances (35-55%) come Friday evening into early Saturday and again Saturday evening into early Sunday. && .DISCUSSION... Issued at 237 AM CDT Wed Jul 2 2025 Early this morning an MCV was moving across eastern Nebraska. Its current track, model guidance, and the lack of any instability over our area all indicate it will weaken and remain north and east of our area this morning. A slightly warmer and more humid couple of days are ahead as more moist southerly flow returns. Thursday, a lee trough begins to develop to our west as the upper-level ridge moves overhead. The ridge slowly gets shunted off to our south and east as the trough deepens on Friday. Models are in good agreement with showers and thunderstorms developing over central and eastern Kansas Friday evening as an upper-level wave ejects into the central Plains. Shear is favored to be nearly non-existent, but with several thousand joules of CAPE and pwats near the max expected for this time of the year, very heavy rain (rain rates over two inches an hour) and some downburst winds would be possible in stronger storms that develop. This wave exits Saturday morning, but another one moves in quickly by Saturday evening, bringing another chance of thunderstorms to the area. There will be daily chances for storms through early next week with quasi zonal flow aloft and southerly, moist flow at the surface in place. Summer temperatures and humidity will likely hold on through next week as well. && .AVIATION /18Z TAFS THROUGH 18Z THURSDAY/... Issued at 1227 PM CDT Wed Jul 2 2025 VFR conditions continue. Some diurnal cu has started to show up on satellite. Otherwise, expect southerly winds just under 10 kts to become lighter through this evening and overnight. && .TOP WATCHES/WARNINGS/ADVISORIES... None. && $$ DISCUSSION...Jones AVIATION...Picha
