Mild Halloween weekend

Patchy Dense Fog is expected throughout SE Wisconsin this morning. A Dense Fog Advisory continues until 9 a.m. A clear and cool morning has allowed patchy fog to develop across SE Wisconsin. Visibility has dropped to as low as ¼ mile in some spots. Fog will clear up by mid-morning. Another beautiful Fall day is in store with highs climbing into the 60s under a mostly sunny sky. Temperatures are expected to fall back into the 40s tonight - with cooler temperatures farther inland. More patchy fog could develop in some spots. A low-pressure system moving through the Mississippi River Valley will spread cloud cover over much of southern Wisconsin Sunday and Monday. Highs will reach into the lower 60s Sunday. A spotty shower/patchy drizzle cannot be completely ruled out for far SE Wisconsin as this low-pressure system passes by. Most areas will stay dry.
