Forecast Discussion
- Relatively cool and comfortable, mostly sunny Labor Day Upper-level ridging and sprawling high pressure over the Great Lakes today into Tuesday will provide tranquil weather. A few daytime cumulus clouds may develop, and good mixing to 850 mb where temperatures are around 7 C should yield highs in the lower 70s today, several degrees cooler than normal. Dew points will be dry and comfortable in the 40s to lower 50s. Tuesday will be a few degrees warmer as a southerly component to the wind commences with the center of high pressure moving east of the area. - Warm mid-week period then a late week cool down with showers A mid-week warming trend takes place due to height rises and southerly return flow on the back side of the departing sfc high. High temps of 80-85 are anticipated for Wednesday and Thursday. That warm up is relatively short lived however as a digging upper trough over central Canada drops our way toward the end of the week. Mainly clear conditions eventually giving way to increasing clouds by later Thursday. The sfc cold front preceding the incoming upper trough passes through the state Thursday night and early Friday bringing the likelihood of a period of showers and storms. This is followed by a surge of rather chilly air for next weekend with highs only in the 60s. Considerable clouds and a threat of showers expected for Saturday with the upper low overhead and cold advection over the warm lake waters (Delta Ts as much as 20C). There is some question as to how quickly the upper low departs the region with some indication that warm advection returns for Sunday so its possible we see some improvement by then.
We really lucked out this season. A vast majority of the US was sweltering with at least 12 heat waves and all time hottest summers. The only part of the US that was spared of that misery was the Great Lakes and upper Midwest regions.
This Summer was a breeze I think 5 90 degree days only out at thee YARDOFBRICKS I will take that any Summer as we look back I will I enjoyed this summers cooler temperatures and all the rain it sure was cloudy alot on the weekends to but I’m not complaining let’s burn baby burn it’s Fall …INDY
Put an extra log on the fire and crack open a nice cold sprite and enjoy the chilly nights ahead Indy!! I may have to have a nice fire out back next week.
100+ my friend one of INDY’s favorites months is here let’s Gooo!! Enjoy to INDY
Wonder if we will see any more 90s this year or if they are history? Interesting to note 3 of our 90degree days didn’t even fall in the official summer season. Only 3 90s in the official summer season so far. We shall see if we can squeeze any more out by Sept. 21 before we move to fall on the 22nd. I have enjoyed this summer. Not overall hot (reflected in the near average summer numbers) and ample rains.
Probably not … but that’s okay with me .. INDY
Me too!!
Interesting summaries for August and met Summer. Both ended up above average after endless posts telling us we were stuck in a below average pattern. One or the other appears to be wrong. They should start tracking humidity and dew points, it’s been a very humid couple of months.
