More September Rain Saturday Then Fabulous Fall Weather
Superb September Weather Soon
What a difference a month makes. September has seen rain eight out of the first eleven days so far for nearly two and a half inches total. All of August saw rain of more than just a trace only 5 times for a total of .80". Yesterday was the fifth day in a row with rain. We haven't seen five days in a row with rain since the middle of May.
Some showers and a few rumbles of thunder today then get set for a stretch of superb September weather starting Sunday afternoon and at least through Thursday.
A shift to southwest winds today should warm us up back into the lower 70s.
So after four days in a row with below average temperatures we can say so long to the 60s for highs at least through next week. Forecast models have highs in the 70s or warmer through next Saturday.
Cooler Pattern Coming
Models are advertising a shift towards cooler weather from the middle of the month through early October. The 6-10 temperature probability forecast has Chicago near or about average overall from September 16th through the 20th. The 8-14 forecast has us outlooked for below average temperatures overall from September 18th through the 24th.
The even longer range forecast has the midwest and eastern half of the country cooler than average for the last week of September and first few days of October.
Drier Pattern Developing
On and off showers are likely today with a few scattered thunderstorms. After today there is very little chance of rain until a week from this Monday. The cloud cover forecast on the meteogram below has plenty of blue. There will be abundant September sunshine beginning Sunday afternoon and through most of next weekend.
Looking longer range this dry pattern could continue through the end of this Month. Both the 6-10 and 8-14 day precipitation probability forecast has Chicago outlooked for below average precipitation overall from September 17th through the 25th.
