Issued at 158 PM CDT Fri Apr 4 2025 Scattered rain showers continue to stream across the region this Friday afternoon as a short wave trough lifts northeast out ahead of the deep larger scale trough currently over AZ. Another storm system was moving over the top of the deep trough, across the far northern Plains. This system will give a push to the cold front which as of 3 PM was on the doorstep of Knox county. As expected, today`s rain showers are associated with the frontal zone to the northwest and the better elevated forcing and frontogenesis from the southern system in our southern areas. The rain in far southeast NE and southwest IA has been light but pretty persistent, while the northwestern frontal zone is a bit more showery. Expect the overall coverage in the southeast to lessen in the coming hours while the advancing frontal zone will continue to support rain showers and some post-frontal drizzle through the evening. There is a pretty good push of post-frontal cold and dry advection incoming, so while there will be an uptick in showers or drizzle for a few hours tonight, it will be pretty short lived and overtaken by drier air, cooler temps, and gusty northwest winds by Saturday. This will make for a pretty raw Saturday with temperatures mainly in the 40s through the afternoon and wind chills ranging from around 20 in the morning to around 40 by mid afternoon. Sunday on the other hand, looks much nicer with a high around 60 and much lighter winds. Model agreement is quite strong in another shot of cold air making a glancing blow on the local area Sunday night into Monday, but then transitioning into a more zonal pattern for the middle of the week with warmer temperatures and a couple of chances for light precipitation with the passage of weak fast- moving moisture- starved short wave troughs late Tuesday into Wednesday night. Then a stronger upper level ridge builds in, bringing even warmer temperatures by late in the week into next weekend. && .AVIATION /06Z TAFS THROUGH 06Z SUNDAY/...
