A few strong or severe storms are possible. - Building heat and humidity early next week will bring a period of heat-related impacts, with heat index values forecast to rise into the middle 90s to around 100F on Monday and Tuesday. && .DISCUSSION... Issued at 206 AM CDT Sat Jul 11 2026 A repeat of yesterday afternoon with isolated showers and storms across north-central and far northeast WI. Highs will be in the 80s. Tranquil conditions expected Saturday night. Meanwhile on Sunday, there is a chance of thunderstorms during the afternoon across the north. The latest Day 2 Outlook from SPC has a Marginal Risk over much of northeast WI. 0-6 km shear and enough CAPE to bring the potential for a strong/severe storms. Still a lot of uncertainty if/when convection breaks out and if its expands across the area. Later shifts may need to expand chances of storms into Sunday night. Temperatures will continue to warm over the weekend as 850mb temps climb to +22C to +24C on Monday. High temperatures will reach into the 90s at most places on Monday and Tuesday. The warmest 850mb temperatures are across the north, thus some of the warmest temperatures may be found up towards Marinette and Iron Mountain. The latest MET/MAV guidance at Iron Mountain indicated 100 on Monday. These values will probably be close to what portions of northern Marinette County will see, especially at our typical hot spots. The latest guidance values indicated dewpoints in the 60s to around 70. These values combined with air temps in the 90s support heat index values of middle 90s to around 100F. A degree or two difference in dewpoint temperatures could make a difference Heat related headlines. The latest numerical guidance for Wednesday would support another hot day. High temperatures will likely go up a few degrees in the coming days. Beyond Wednesday, the details are murky when the next chance of storms arrive across the area, but the latest model run would indicate Friday, compared to Thursday yesterday. Temperatures should trend slightly downward late in the week, but remain well above normal. && .AVIATION...for 06Z TAF Issuance Issued at 1100 PM CDT Fri Jul 10 2026 Scattered mid and high clouds occur overnight. Fog should develop 08z-12z at RHI (LIFR-IFR) where rain this afternoon added moisture to otherwise drying boundary layer. Due to the drying boundary layer and min temps mainly staying above the crossover temps, continue to leave fog out elsewhere overnight. On Saturday, VFR cu (040-060) should blossom, especially northern WI late morning through the afternoon. A stray shower (15-20% coverage) is possible central to northern WI in the afternoon, but with pops low, did not included a mention of rain at RHI. If it would occur, 18z-23z would be most favored time. && .GRB WATCHES/WARNINGS/ADVISORIES... None. && $$ DISCUSSION.....Eckberg AVIATION.......JLA
