A Cooler Week Coming? Not so fast.

Public weather briefing

After a warmer than average week, temps will be dropping slightly this evening as cooler air moves into the region from the north.  This evening a slight chance of light rain exists but it is unlikely throughout the night.  The next couple days will be pleasant with mild temperatures and mostly clear skies.  As next week begins, warmer temperatures are expected to return.  There is a slight chance of showers on Monday but nice weather similar to this week will follow.  

Tonight. Slight chance of showers early in the evening.  Lows in lower 50's. 

Friday. Overcast in the morning with gradual breakage in cloud cover later.  High of 58.  

Friday night. Mostly clear skies with lows in the lower 40's.

Saturday. Sunny and warmer with a high of 68.

Sunday. Sunny and warmer with a high of 75.  

Outlook for Monday through Tuesday. Slight chance of rain on Monday with a high of 68.  Tuesday will be slightly cooler but clear with a high of 63.  Lows will be in the mid-40's.[CONFIDENCE: MEDIUM]

Forecast Discussion

A low pressure center situated over northern Wisconsin has moved in from Manitoba forcing cold air advection into the midwest. Accent and moderate rain is being driven east of the low by differential warm air advection from the southwest while some showers may be expected in southern Wisconsin along the cold front.  With the passage of the front, temperatures will quickly drop into the mid-50's with dew points in the upper-40's.   As the cyclone tracks eastward, cooler temps will remain into Saturday morning but with a warming trend beginning in the afternoon as the short wave trough passes and zonal wind advects warm air from the plains.
