Issued at 158 AM CDT Mon Sep 14 2026 Forecast for a a round or two of heavy rain this afternoon through Tuesday morning remains on track. A strong low pressure system is evident on WV imagery over the northern Rockies early this morning. This system will progress east into the northern Plains today with strengthening southerly flow ahead of the low drawing seasonally high moisture into the region. Expect rain to initially push into central WI during the early afternoon, however, the exact timing for the onset of precipitation remains somewhat uncertain as forecast soundings do show dry air in the low-levels that will need to be overcome. This initial round will likely be light to moderate widespread rain that spreads across the area by afternoon. A second round of rain is then expected beginning this evenings over central WI as a strong LLJ pushes noises into the region. This second round is expected to bring a more focused area of moderate to heavy rain to central and east- central WI late this evening and overnight. Between these two rounds of rain HREF LPMM 24hr rainfall totals show a corridor of 2-3" totals south of a line from Wausau to Sturgeon Bay with 0.5 to 1" north of that line. The exact placement of this higher end corridor may still shift north or south slightly. A few embedded thunderstorms are possible with this system, but weak instability keeps the severe threat low. Rain will come to an end from west to east Tuesday morning high pressure them bringing dry conditions for the remains of Tuesday and much of Wednesday. For the remainder of the week a baroclinic zone is expected set up over or just south of the forecast area. This will keep a 40-70% chance for showers and occasional thunderstorms Wednesday afternoon through next weekend, however, it will likely not rain that entire period. Temperatures will hover near to slightly below normal next week depending on where the boundary sets up each day. && .AVIATION...for 06Z TAF Issuance Issued at 1106 PM CDT Sun Sep 13 2026 VFR conditions persist through Monday afternoon, before conditions deteriorate Monday evening into early Tuesday.
