The familiar “cooler near the lake” will certainly be the key to the Chicago metro area weather over the next few days. Each day for the next three, a lake breeze (see graphic on left) will play a role in the temperature forecast.
High pressure will be nosing down over lake MI Saturday to produce a light east wind. This will result in highs ranging from only the upper 40s north shore to the mid 60s far south and west portions of the metro area. For Sunday and Monday I am looking for highs in the 50s lakeside but around 80 south and west as a warm front bobs around the metro area. A 25+ degree temperature spread over the metro area. Summer south and west to warm jacket east. For those areas that reach highs around 80, there will be a noticeable jump in the humidity levels as dew points jump well into the 50s to produce the real summer feel to the air. This front “may” touch off some storm late Saturday night/Sunday morning.
Our recent record breaking warm weather has certainly brought an extremely early start to all the plants developing into their seasonal growth patterns. It is still early, we are still likely to have some freezing weather. There is an excellent article available here from the Midwest Regional Climate Center that details the expected last dates of freezing weather in the area. There should be no rush to bring out plants that are susceptible to frosts or freezing.
