Forecast Discussion
A shortwave thermal ridge sits over Wisconsin on Monday which is advecting warm temperatures into the area for a few days. Confluence of northwesterly winds causes a weak low pressure system to form Tuesday night over Wisconsin which is the cause of the slight chance of rain during the night. A small thermal trough then propagates eastward on Wednesday causing a slight drop in temperatures. Another thermal ridge propagates over Wisconsin bringing warmer temperatures and slightly stronger winds on Thursday. No strong jets can be found over Wisconsin over the week which corresponds to the lack of strong, organized low pressure systems during the week.
