Back On The Temperature Rollercoaster

So Long To 30s For Now


After back to back highs in the 30s at O'Hare we will warm up a bit heading into the weekend. Those 30s were the coldest highs we have seen in just over 8 months. The last time we were that chilly for two days in a row was late March.


Today's highs should still be below the average of 58° but it will be an improvement over the past few days. Highs today should climb to near or just above 50°.


Strap in for a somewhat bumpy temperature rollercoaster ride the next several days. A few degrees cooler tomorrow & blustery then we are headed uphill through the start of the weekend. Gusty southwest winds should push our highs well into the 50s Saturday. We will fall back into the lower 40s by Sunday and then recover a bit by Tuesday when highs top 50° again.



Surge Of Tropical Moisture Stays South


The remnants of Hurricane Zeta will stay south of us later this week. Southern Illinois could get between 3 and 4 inches of rain but we will be spared. There could be a few spotty sprinkles Thursday mainly south of the city but most of us will stay dry right through the weekend.


While Zeta's rain will miss us we won't get out unscathed from the storms remnants. It will help to whip up strong northeast winds here tomorrow that could produce some big waves along Lake Michigan's shoreline here. Lakeshore flooding is a possibility. At the very least, those gusty winds combined with highs in the 40s will make it feel more like December than late October.


Back Above Average For November?


The longer range forecasts continue to suggest we will warm back up above average for much of next month. The 6-10 day temperature probability forecast has us outlooked for about near normal temperatures overall from November 2nd through the November 6th. The longer range 8-14 day forecast has outlooked climbing above average overall from November 4th through the 10th.



The even long range experimental multi-ensemble model forecasts keep us outlooked above average through the second and third weeks of November. The forecasts for the week ending November 13th and the week ending November 20th have us outlooked above average too.




Dry Halloween & Well Beyond


There is a chance for a little light rain well south of the city Thursday but overall there seems to be a drier pattern developing both in the short and longer term. After Thursday the the next threat of rain isn't until a week from Friday.



The longer range forecasts keep us drier than average into the middle of next month. The 6-10 day forecast has us outlooked for below average precipitation from November 2nd through the November 6th. The longer range 8-14 day also has us favored for below average precipitation from November 4th through November 10th.




Snow Cover Continues To Pile Up


A comparison of snow cover this year to last shows a remarkable contrast. As of yesterday, 34.5% of the country was reporting snow cover with an average depth of 1.2". Last year at this time just 6.3% of the country had snow cover with an average depth of .2". We have nearly six times mover snow cover now compared to a year ago. That could be good news for snow lovers this winter. More on that and my winter forecast coming up in a special blog post next week.



Here is my 7 day forecast:


Today: Mostly sunny High: 52


Thursday: Mostly cloudy, blustery, spotty sprinkles south Low: 39 High: 48

Friday: Mostly sunny Low: 33 High: 48


Saturday: Mostly sunny Low: 32 High: 55


Sunday: Partly to mostly sunny, windy & colder Low: 36 High: 42

Monday: Mostly sunny Low: 29 High: 50


Tuesday: Mostly sunny Low: 35 High: 59
