869 FXUS63 KICT 050914 AFDICT Area Forecast Discussion National Weather Service Wichita KS 314 AM CST Wed Feb 5 2025 .KEY MESSAGES... - Freezing drizzle this morning and associated travel impacts, especially during the morning rush. - Fog likely tonight for areas along and east of the KS Turnpike. - Below normal temps starting Sunday and continuing through most of next week. && .DISCUSSION... Issued at 314 AM CST Wed Feb 5 2025 Cold front currently stretches from the Arklatex region through Central TX with a shallow cold airmass still in place across the Plains. In the upper levels, water vapor imagery shows a couple different impulses. One lifting across the Pacific Northwest, with another piece of energy tracking across eastern WY/western Nebraska. Most of south central and southeast KS are still getting a mix of drizzle and BR with visibilities generally in the 3 to 6sm range. Isentropic upglide in the low level saturated layer has been a good indicator of where the drizzle has been occurring and it has been fairly persistent over the last few hours. There has been some consistency with the models in ramping up isentropic lift/low level theta-e advection in the 12-15z time frame with models also increasing the saturated layer by around 2,000 ft. Feel this will lead to more intense drizzle and freezing drizzle this morning, possibly during the morning rush. Previous forecaster mentioned ground temps in the mid/upper 30s where freezing drizzle has been occurring, and this has likely helped roads from getting too bad. However, we have seen an uptick in accidents on overpasses here in Wichita overnight and would expect this to continue, especially during the morning rush. Upper impulse is expected to move into western KS by this afternoon and will veer the low level flow and push the better moisture transport east as the day continues. So by around 18z, feel mainly eastern KS will be seeing drizzle/light rain. The good news is that most of that area should be above freezing by then. Did go ahead and insert some fog for tonight as we really never get rid of the low level moisture until the front comes through early Thu morning. Very progressive pattern will remain in place and there is good model agreement that a fast moving upper perturbation will track out of the Northern Intermountain and across the Northern Plains by Sat morning. Ahead of this wave we are looking for return flow starting back up for Fri and Fri night, with a cold front moving through on Sat. This will bring a return to below normal temps for Sun with below normal temps expected to continue through at least Tue and possibly longer. && .AVIATION /06Z TAFS THROUGH 06Z THURSDAY/... Issued at 1156 PM CST Tue Feb 4 2025 IFR to near-LIFR cigs are expected for a majority of the period as drizzle and freezing drizzle persist through the morning hours. Best chances for freezing drizzle remain in central and south central KS, while precip should remain liquid in southeast KS. Current guidance suggests cigs should lift from west to east by late afternoon and early evening as temperatures gradually creep above freezing. && .ICT WATCHES/WARNINGS/ADVISORIES... Winter Weather Advisory until noon CST today for KSZ050>053- 067>071-082-083-091>094. && $$ DISCUSSION...RBL AVIATION...JWK
