352 FXUS63 KTOP 120730 AFDTOP Area Forecast Discussion National Weather Service Topeka KS 230 AM CDT Mon May 12 2025 .KEY MESSAGES... - Warm conditions continue through the week. Wednesday will be the warmest day with highs in the low 90s. - There is a low chance (15%) for rain across far northern Kansas Wednesday night with better chances coming over the weekend. && .DISCUSSION... Issued at 230 AM CDT Mon May 12 2025 Little change to the synoptic pattern has occurred across the region over the last 12-24 hours with the closed upper low spinning near the Gulf Coast and surface ridging in control of the Central Plains. The upper low does make some progress northeast today, but will track far enough east to keep any precipitation and the majority of cloud cover away from the local area. A very similar day to yesterday is expected with mostly sunny skies and highs in the low to mid 80s. The closed low continues its eastward propagation, allowing for mid-level ridging to build across the Central Plains for Tuesday and Wednesday. Increasing southerly winds will gradually warm temperatures through Wednesday, when the warmth will peak as 850mb temperatures warm to 20-22 degrees C. This will translate to highs approaching record values in the mid 80s to near 90 degrees on Tuesday and in the 90s for most locales on Wednesday. A longwave trough and associated cold front will sweep across the Plains Wednesday evening into Thursday. A lack of deep moisture and the northern displacement of the strongest forcing favors a mainly dry passage of this system, although there could (10-15%) be a few showers near the KS/NE stateline. Temperatures behind the front are slightly cooler, but highs will still be in the low to mid 80s through the end of the week. A shortwave ejects across the Plains on Friday, although uncertainty in the location of the surface boundary and overall moisture quality leads to low confidence in precipitation chances with this wave. Only about 10% of members from both the GEFS and ENS generate measurable precipitation on Friday with the higher chances remaining to our south and east. Model variability remains high for the weekend into early next week with models offering a variety of different depictions in regards to location of the surface boundary as it lifts back north and the favored timing of ejecting waves and associated precipitation chances. Nonetheless, a more active pattern with chances for showers and storms begins late Saturday and continues into Monday of next week. && .AVIATION /06Z TAFS THROUGH 06Z TUESDAY/...
