Temperatures will also be alignment with the dry pattern. Meaning, we'll break the below normal trend and warm back up. In fact, i'm pretty sure the rest of the months high temperatures will be above normal, which is above 84°. We'll say goodbye to the 70s and see more mid to upper 80s and yes, just maybe even a 90 to wrap up the month. Summer is back. By the way, it still is summer too folks.
The latest 100° day was recorded September 15, 1939 of 100°. We recorded 100° last year on September 4th.

METEOROLOGICAL SUMMER (JUNE-JULY-AUGUST)
Its been a warm summer, but with the recent cool off this has dropped us down the list from being the #1. We now only have 2 weeks left of meteorological summer and 5 weeks left of astronomical summer. About 78% (62 days) out of the past 79 days have been above normal. The average high for this season is 89.5° with an avg low of 66.5°. This puts the avg temperature this summer (Since June 1) at 78° which is about 5° above normal. This season is currently the 5th warmest summer on record. Here's the Top Five list:
2) 1936---78.5°
3) 1934---78.2°
4) 2010---78.1°
2012---78°
5) 2011---77.6°
We usually don't talk about it much in the summer but over the past 2 days some record lows have been challenged. On Friday, in Kauai County, Hawaii, they set a new record low of 44°. This was 21° chillier than the previous record of 65° set in1975. Also in Sioux County, Iowa, they broke an 11 yr old record low by 10° from 49° set in 2001 to a new record low of 39° Friday.
On Saturday, in Hartley County, Texas they set a new record low of 42°. This was 13° cooler than the record set 4 yrs ago of 55°. We tied a record low here in Marion County yesterday on the Southeast side of Indianapolis. Yesterdays low of 50° is shared with the record low set in 1963. The same temperature was also tied in Vermillion County Indiana shared with a record low set in 1992 there.
According to the National Climatic Data Center, of around 7,000 possible records, there was 263 record lows tied or broken on Friday and Saturday combined. Most of these records were recorded in the upper midwest & midwest in Illinois, Iowa, Kansas, Missouri, Nebraska Minnesota, and South Dakota. Here's a handy link for those that want to look through some of the records set in the U.S. These date back to 1850 and not only go for just lows but for record highs, rainfall, and snowfall.
A very weak disturbance could bring a stray shower this afternoon and Monday but this isn't a very good chance and will likely not bring a drop to much of the state. The majority of the state should stay dry with some sunshine for this Sunday and Monday Afternoon. It will be a pleasant and dry week ahead. High should top out at or around 80° today and tomorrow before we begin a warming trend to possibly 90s on Friday. I made a note in my 7 day below there will be a chance for some thunderstorms this next weekend but right now Saturday looks drier than Sunday. These again, are low chances but it looks greater than today and tomorrow so likely, some areas in the state could actually record a few raindrops. Just a little heads up if your in the process of making any outdoor plans.

UPCOMING......
I expect temperatures to remain at or above normal for the next few weeks. There is an indication however that possibly by the second week of September around the 10th a weak block will form in Greenland. This could put the North Atlantic Oscillation (NAO) back into negative phases but isn't entirely clear. When the NOA goes into negative phases this means cooler air is sent southbound and our temperatures will fall back. I expect temperatures if not to be near normal, to go below normal. We could go back to thermometer readings into the mid to low 70s for highs. Typically we do have a strong Jet Stream mid to late September. What does that mean? Well I wouldn't be surprised if we saw some high temperature readings in the 60s and lows in the 40s around this time. I took a look back over the past 5 years and compiled a list of our first 60° highs and 40° lows, if any, in September. In 2008 & 2009 there wasn't a low in the 40s. The lowest was 50° in 2009 and 51° in 2008.
September 15th-Low of 46°
2) 2010: September 26th-High of 65°
September 4th-Low of 48°
3) 2009: September 25th-High of 67°
4) 2008: September 15th-High of 67°
5) 2007: September 15th-High of 64°
September 12th-Low of 49°
