FXUS63 KTOP 032320 AFDTOP Area Forecast Discussion National Weather Service Topeka KS 520 PM CST Tue Feb 3 2026 .KEY MESSAGES... - There is a low chance (10-20%) for a very light wintry mix in north central KS overnight into Wednesday morning. - Weather trends warm and dry the rest of the week into early next week. && .DISCUSSION... Issued at 245 PM CST Tue Feb 3 2026 Water vapor imagery at 20Z continues to show northwest flow aloft from the northern Rockies into the High Plains. A ridge is situated upstream and is amplifying over the West Coast. VAD wind profilers at 500mb indicate a subtle perturbation within the the northwest flow pattern in the CO/NE/KS vicinity. At the surface, high pressure centered over MN has been building south into the forecast area and pushing a sfc low southeast towards the lower Mississippi River Valley. This should increase subsidence across the area this afternoon into the evening. For the overnight hours, short-term model guidance has trended towards keeping reflectivity west of the area where the better forcing for ascent appears to be. Further east into our area, there is a shallow saturated layer below the DGZ with perhaps an hour or two of time when there could be just enough lift to squeeze out some freezing drizzle. That narrow time frame has trended later, likely after 09Z if it occurs at all. Notably, the HRRR has shown more reflectivity in our western counties during the afternoon hours Wednesday than at any other point before then. Vertical lift still doesn't look very impressive at that time frame, but might be a little better than the morning. Overall, the forecast appears to be trending toward a dry outcome, as you have to get to the 90th percentile to find any QPF. As such, have kept PoPs low to account for any limited possibility of freezing precip Wednesday morning. If the afternoon time frame does pan out, fortunately temperatures look to warm above freezing by then and would more likely be dealing with drizzle for a brief time. Outside of low precip chances, we transition to meridional flow aloft Wednesday as the upper ridge builds eastward. This sets up a warming trend into Thursday with rising heights and WAA helping to boost temperatures into the 50s and low 60s. Similar highs are forecast through Monday of next week. Spreads in the ensembles become larger by Sunday, but even so, the NBM suggests above average temperatures are favored. The next precip chance may come next Tuesday, but a lack of consistency between models keeps PoPs low for now. && .AVIATION /00Z TAFS THROUGH 00Z THURSDAY/... Issued at 520 PM CST Tue Feb 3 2026 Stratus around VFR/MVFR border looks to dominate this forecast as a damp, cool airmass lingers. Confidence in which side of this border clouds will be is low to moderate. Expect slow cooling to allow for lowering ceiling heights over the next several hours, lowering TOP and FOE to MVFR. Models are rather pessimistic with any improvements, but will continue on the diurnal trend idea with VFR returning late at all sites. && .TOP WATCHES/WARNINGS/ADVISORIES... None. && $$ DISCUSSION...Picha AVIATION...Poage
