Chicago WX Posted October 30, 2011 Share Posted October 30, 2011 Not sure about elsewhere but it's unreal how this month is mirroring October 2008 in terms of temp departures. Below average the first few days, then about 2 weeks above average, then about a week below average, then a few days above and a few days below. First week of this November looks like a blowtorch too, just like Nov 2008. Well, maybe this one won't be as warm. Link to comment Share on other sites More sharing options...
Chicago Storm Posted October 30, 2011 Author Share Posted October 30, 2011 Thanks...that's crazy. I guess UHI existed back then too...or at a minium, the Fall was very mild up to that point and kept the lake water temp above normal. That was back when the official OBS site was on the near south side, at Rosenwald Hall (University of Chicago)...so the UHI and lake likely played a role.

I've been thinking the same thing...I'm glad you had the guts to say it Link to comment Share on other sites More sharing options...

Right...this is when you wish there was a consistent "official" site for Chicago...but I know that has been discussed many times already. Regardless, it's hard to believe it took until Nov. 24 to hit freezing at that site. Of course 1930 could have been similar to what's happening at ORD this Fall, i.e. many nights close to freezing but never quite making it. Link to comment Share on other sites More sharing options...
turtlehurricane Posted October 31, 2011 Share Posted October 31, 2011 The center of the longwave trough is coming directly overhead southern Wisconsin now, -28° C at 500 hPa. Coldest 500 hPa temperatures in the USA (besides AK probably) for the moment. Link to comment Share on other sites More sharing options...

cyclone77 Posted November 1, 2011 Share Posted November 1, 2011 Less than 3/4" of precip here for the month of October. Can't remember the last time we had such a dry month. We've had a lot of very wet months over the past few years though, so we were long overdue. Definitely the best time of the year to have a dry month too lol.

BowMeHunter Posted November 1, 2011 Share Posted November 1, 2011 Torching high temps month.. at least the night time lows the second half of the month made for good sleeping weather and could put the endless ac weather to bed for another 7+ months. Still a shat load of leaves to come down for the usual late droppers. need a good freeze close to the lake and they will drop like prom dresses.

on_wx Posted November 4, 2011 Share Posted November 4, 2011 University of Waterloo Weather Station Summary - October 2011 A hot month that was the third wettest October ever seen After a really hot start to the month where the temperature was over 10 degrees higher than average for 3 days, it came down to more of what we would expect for the rest of the month. The overall temperature was one and half degrees warmer than average which means we have to go all the way back to March to find a colder than average month. On the morning of October 23rd at 4:45 am the temperature went below zero for the first time since the spring and thus the frost free season went from May 1st to October 22nd this year which is a total of 175 days. This is the longest frost free season since records began in the region in 1915, just beating out 1941 when they had a stretch of 174 days above zero. Even with a dry start to the month, the 114 mm in the next 8 days got us on the way to the third wettest October since records began in the region. The 141.9 mm we saw this month was only a little behind the 151.4 mm in 1955, but way back of the 195.4 mm in 1954. With June and July coming in as the only two drier than average months and a really wet October we are back talking about how wet 2011 has been. In fact at 941.0 mm for the year so far, it is the fourth wettest first 10 months on record. Summary for October 2011: Maximum Temperature 26.7°C Minimum Temperature -3.3°C Average Daily High Temperature 14.1°C (Long term average 13.2°C) Average Daily Low Temperature 5.0°C (Long term average 2.9°C) Total Precipitation 141.9 mm (Long term average 67.1 mm) (Long term averages based on 1971-2000 data for the Waterloo Wellington Airport) Link to comment Share on other sites More sharing options...
