Severe storms are not expected. - Will need to watch precipitation trends this weekend. A few storms are possible Saturday and Sunday. - Trends continue to be monitored for the excessive heat potential early next week with highs in the 90s at some locations. && .DISCUSSION... Issued at 145 AM CDT Thu Jul 9 2026 Scattered showers continued early this morning near Rhinelander and Merrill eastward into northern Door County ahead of a weak cold front that is expected to sag southward today. As the front sags southward, rain chances return to central and east-central WI this morning which will continue into the afternoon. Bufkit soundings indicated 500 to 800 J/KG of CAPE and shear values around 20 knots, thus not expecting severe weather today. The showers and storms will end from north to south this afternoon. Tranquil conditions are expected on Friday. A new wrinkle to the forecast for the weekend. High pressure is expected to set up across the state. Return flow/850mb warm advection sets up Friday night, which should result in scattered thunderstorms developing across Minnesota and western WI. Some of the activity may spill into far north-central WI towards 12z Saturday. The combination of daytime heating and possibly an outflow boundary from the overnight convection is expected to bring a chance of showers and storms across the north Saturday afternoon. Confidence is low on a dry forecast for Sunday as the Canadian/ECMWF are bringing a weak impulse across the area at 500mb. The ECMWF is more bullish than the Canadian model on the QPF output for Sunday. Will continue to monitor to see if rain will need to be added for this period. 500mb ridge builds early next week, resulting increasing heat and humidity later this weekend through the middle of next week. 850mb temperatures are pretty toasty off the ECMWF/Canadian/GFS that would support highs in the lower to middle 90s at our typical hot spots. Current forecast is a little bit lower that what the max values would be each day. None the less, it will be hot. && .AVIATION...for 06Z TAF Issuance Issued at 1050 PM CDT Wed Jul 8 2026 Isolated to scattered showers and a couple storms will continue overnight into Thursday morning as a cold front sags south across the area. Main hazards will be heavy rain and lightning. Ceilings and visibilities will drop through the night as low clouds and fog spread in/develop, with IFR/LIFR conditions for much of the area. Some VLIFR conditions are possible, especially across northern WI. The fog will lift Thursday morning, with clearing skies expected in the afternoon. Patchy/areas of fog is again expected Thursday evening/night. Winds will remain under 10 kts. && .GRB WATCHES/WARNINGS/ADVISORIES... None. && $$ DISCUSSION.....Eckberg AVIATION.......Bersch
