Public weather briefingAfter a very nice Monday, the great weather continues for most of the week. Warm temperatures will be continue throughout the week. Temperatures will stay in the low 70's for the middle of the week and rise to the mid to high 70's for the end of the week and start of the weekend. Lows will be in the low to mid 50's throughout the week as well. It should be, for the most part, a clear and sunny week due to the high pressure system located over the area. However, with a system to the west-southwest, the outlook for rain is now possible for Wednesday night into Thursday morning's forecast. Along with early morning fog for the middle of the week, these should be the only threats to what should be an overall excellent week and weekend outlook.
Tonight. Clear skies with light wind from the south. Low around 50.
Wednesday. Clear morning with clouds increasing throughout the day becoming mostly cloudy. Possibility of showers in the evening. High around 70.
Wednesday night. Cloudy with light southerly winds. Lows in the lower 50's. Chance of showers into Thursday morning.

Outlook for Saturday through Monday. Mostly sunny all weekend into the early week. Temperature highs in the low to mid 70's with lows in the 50's throughout the weekend. [CONFIDENCE: MEDIUM-HIGH]
Temperatures will continue to slowly rise throughout the week, going from the low 70's in the middle of the week to the mid to high 70's later in the week. This is due to the warm air advection coming from the south carried north to the upper midwest region. Low's will be consistently in low 50's bringing on the chance of condensation at the low levels of the atmosphere. This could pose a threat for fog into Friday morning's forecast.
Yesterday's forecast showed a low pressure trough that looked to be dying out before reaching the Madison area. However, models now show that this system will continue to move northeast into the area giving the chance for precipitation in the central and northern regions of Wisconsin stretching into Madison for Wednesday night and into Thursday morning before finally dying out shortly after. This is due to the severe curvature of the cyclone in Minnesota-South Dakota-Iowa region creating divergence in the upper atmosphere to the east causing lifting, which leads to precipitation in this western region.
