A Lovely Labor Day Then Some Soggy September Weather

We put a dent in the drought. Sunday's rainfall varied from around a quarter of an inch in the city to nearly two inches well west of Chicago. O'Hare picked up .6" while West Chicago saw 1.33" of rain. There's more where that came from. A more active pattern is shaping up for this week beginning late tonight into early Tuesday.


The best chances for rain will be late tonight into early Tuesday and then late Tuesday night into early Wednesday. Another round of scattered showers and possible thunderstorms is also possible on Saturday.


The GFS model is forecasting between three quarters of an inch and an inch of rain between tonight through Thursday afternoon.



We need to grab all the rain we can get this week because the long range outlook drys us out for the middle of the month. Both the 6-10 day and 8-14 day precipitation probability forecasts have us outlooked for below average rainfall overall. This covers the period from September 12th through the 20th.



Today's highs will in the lower to middle 70s. If we don't get above 74° it will be the coolest day in almost six weeks. Wind will pick up off the lake later today so watch for temperatures to cool late in the afternoon.



We can say so long to the 80s and 90s at least through this weekend. The flip to a more wet pattern comes with a cooler pattern kicking in at the same time. It should be cooler than average all this week (average high is in the upper 70s). That cooler air could keep on coming right through the middle of the month. Both the 6-10 day and 8-14 day temperature probability forecasts have us outlooked for cooler than average temperatures overall covering the period of September 12th through the 20th.



Winds off the lake later on Labor Day and into Tuesday will not only cool us off but they will also whip up some big waves along our shoreline. A beach hazards statement is in effect from Monday afternoon through Tuesday evening. 3 to 5 foot waves are possible along with strong rip currents.

Here is my 7 day forecast:
