692 FXUS63 KTOP 121710 AFDTOP Area Forecast Discussion National Weather Service Topeka KS 1110 AM CST Wed Nov 12 2025 .KEY MESSAGES... - Dry and warm weather with above normal temperatures is forecast to continue into the weekend. - A weather system may bring some rain on Monday, but there is high variability in the forecast so things could still change. && .DISCUSSION... Issued at 237 AM CST Wed Nov 12 2025 08Z water vapor showed upper ridging over the western U.S. with an upper trough over New England. This placed the central plains under northwest flow. Surface obs showed weak high pressure over the plains. The next several days are expected to be relatively quite with no significant wave progged to impact the region until early next week. Northwest flow persists into Saturday with only some low level moisture return. Meanwhile continued low level warm air advection looks to keep a cap over the moisture return with only minor perturbations expected. So dry and warm weather is forecast to persist into Saturday. The weak high pressure in place today should delay the stronger warm air advection to Thursday and keep highs generally in the middle 60s. But for Thursday through Saturday, confidence is good we should see highs in the upper 60s and middle 70s. This is supported by small spreads from the ensemble and NBM solutions. The main question in the forecast is what will the upper energy coming out of the southwest look like early next week. Models have struggled to show any consistency and the large spreads seen in the ensembles is reflective of the low predictability of the pattern. The general time line from the 00Z operational solutions is for a wave lifting into the plains is during the day Monday. But models continue to flip between an open and closed wave with various tracks to the system. The timing of the system is captured in the NBM initialization and have no confidence in any individual model run to deviate from the mean at this point. So the forecast has some chance POPs late Sunday night and Monday with temps much closer to normal to start off next week. Until the models get a better grasp on the pattern, the details in timing of precip and temps are probably going to change as the spread between the 25 and 75 percentile is almost 20 degrees. && .AVIATION /18Z TAFS THROUGH 18Z THURSDAY/...
