Weather Overview
Western Wisconsin can expect above normal temperatures for the remainder of the week, influenced by a strong upper-level ridge keeping conditions mostly stable. However, tonight will bring a potential for dense valley fog.
According to the National Weather Service, fog development is anticipated due to clear skies and calm winds. The probabilities for visibility dropping below one mile are between 30-40% in various valleys. Expect the fog to linger through the morning before dissipating around 10-11 AM.
Looking Ahead: Weekend Rain Chances
As we move toward the weekend, an upper-level disturbance will approach the area. While the upper ridge begins to break down late Saturday, a cold front may bring some light rain possibilities.
At this stage, the forecast indicates a 10-20% chance of precipitation late Saturday into Sunday morning. The specifics of rainfall amounts and exact positioning of the front remain uncertain, with the potential for conditions to improve or worsen depending on the front’s movement.
Early Next Week: Cooler and Wetter
Moving into early next week, indications suggest a trend toward cooler and wetter conditions. A shortwave moving through the region could lead to precipitation chances increasing to about 30-50% for Monday and Tuesday. While more clarity is needed, be prepared for changing weather patterns.
