Area Forecast Discussion National Weather Service Topeka KS 350 PM CDT Tue Jun 9 2020 .SHORT TERM...(This evening through tonight) Issued at 350 PM CDT Tue Jun 9 2020 As of 20z this afternoon, remnants of Cristobal continued to move to the north across the Mississippi Valley with a second mid-level wave ejecting over the central Plains. Surface low pressure in central Kansas has deepened to 994mb on the lee of the Rockies with a strong pressure gradient present behind the low over western Kansas. A dry line was observed extending from the low to the southeast along a line from Salina to just south of Emporia extending south from there. Ahead of the boundary, cumulus has developed in an environment favorable for strong to severe storms as the 19z TOP sounding shows approx. 2500 J/KG of surface based CAPE with 45-50 kts of bulk shear. Over the next few hours, expecting convective initiation to develop along and north of the aforementioned boundary with all severe hazards possible (including a few tornadoes). The best chance for storms and tornadoes is near the KS/NE border where ESE surface winds will increase low-level storm relative helicity. These storms should move across the area fairly quickly with the severe threat ending by 8-9pm tonight. Additional showers and thunderstorms are possible in the deformation zone of the surface low overnight before the mid-level wave ejects east of the forecast area by early to mid-morning on Wednesday. Only minor concerns for flooding at this point given the progressive nature of the storms this afternoon and only light to moderate rainfall overnight; will continue to monitor the flooding threat as precip builds in. Lows fall into the 50s tonight behind the surface cold front. The pressure gradient increases on the back side of the surface low leading to strong and damaging winds overnight. 50-60kt 925mb winds and 850mb winds approaching 70kt will move across the CWA, allowing for sustained northwest winds of 30 to 40 mph with gusts up to 60 mph in the western half of the CWA where the High Wind Warning is in place tonight through early Wednesday morning. Will keep the Wind Advisory for the eastern half of the CWA through tomorrow morning; still thinking winds will fall short of wind warning criteria with gusts up to 50 mph possible. .LONG TERM...(Wednesday through Tuesday) Issued at 350 PM CDT Tue Jun 9 2020 A few lingering showers may be around to start the day Wednesday before the system departs to the east. Winds begin to relax during the afternoon Wednesday with highs much cooler than they have been for the past week, only reaching into the upper 70s. For the rest of the week and into the weekend, ridging builds into the Plains keeping conditions dry with temperatures climbing back to near 90 degrees by the weekend. && .AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon) Issued at 1243 PM CDT Tue Jun 9 2020 VFR conditions will continue through at least the first half of the period. There is low confidence in TS impacting terminals this afternoon, so have left VCTS with VFR conditions through this evening. MVFR cigs and precip build in overnight with winds becoming strong and remaining so through the period. Precip is expected to end by mid-morning. && .TOP WATCHES/WARNINGS/ADVISORIES... Wind Advisory from 1 AM to noon CDT Wednesday for KSZ011-012-023- 024-026-038>040-054>056-058-059.
