Area forecast discussion, Sep 7, 6:20 PM CDT, 35 minutes before
Area Forecast Discussion National Weather Service Wichita KS 620 PM CDT Tue Sep 7 2021 .SHORT TERM...(This evening through Friday night) Issued at 245 PM CDT Tue Sep 7 2021 After the slight chances for late day convection as mentioned above along the cold front in southeast Kansas, much drier and somewhat cooler air will advect south across Kansas tonight through Wednesday. Surface high pressure drifting south from the northern Plains into mid-America will influence our weather thru Thursday. Much warmer southerly low level return flow by Thursday afternoon will support temperatures closer to 90F again across central Kansas. The upper ridge over the western conus will slide eastward across the Rockies into the high Plains during Friday. This will support much warmer temperatures well into the 90s across central and southeast Kansas. Darmofal .LONG TERM...(Saturday through Tuesday) Issued at 245 PM CDT Tue Sep 7 2021 An upper trof moving from the Pacific Northwest eastward along the northern tier of states looks to flatten the upper ridge over the weekend. This may allow a weak cold front to slip as far south as northern Kansas, before retreating north again by early Monday. There is still enough spread among the medium range operational models and ensemble solutions into early next week with the regard to the mean flow and any potential for a significant cool down or precip chances, which looks doubtful at this time. So will keep the forecast dry with temperatures above climo. KED && .AVIATION...(For the 00Z TAFS through 00Z Wednesday evening) Issued at 619 PM CDT Tue Sep 7 2021 VFR conditions are expected for the most locations over the next 24 hours. The only exception will be along a sharp cold front currently moving across southern and southeast KS. Isolated convection may develop along the front primarily for areas east of the KS Turnpike along a pre-frontal trough. If a storm can get going and affect the KCNU taf sight, some MVFR vsbys may occur with the TSRA. For now, uncertainty on KCNU being affected by a storm is high, so will only mention a VCTS at KCNU for a few hours this evening. The cold frontal boundary will push into nrn OK in the next few hours bringing the storm chances to an end, with north winds dominating the pattern into Wed.
