The Tulsa area has experienced relatively cool temperatures this October. We have also received above normal amounts of rainfall for both the month and the year. So far for the month of October, we have received 4.39" of rainfall. That is 1.42" of rainfall above normal for this point in October. We have already received 41.91" of rainfall for the year which is 6.47" above normal. The average amount of rainfall for a year is 42.42", and we have almost received that amount in 10 months!

So far this month, October has seen high temperatures mostly in the 60s. Breaking down the high temperatures, Tulsa has had one day with highs in the 80s, five days with highs in the 70s, ten days with highs in the 60s, and six days with highs in the 50s for the month so far. Compare that with high temperatures for 2008 and 2007 and you will notice a big difference. In 2008 Tulsa experienced eight days with high temperatures in the 80s, sixteen days with highs in the 70s, five days with highs in the 60s, and two days with highs in the 50s. In 2007 Tulsa endured one day with high temperatures in the 90s, twelve days with highs in the 80s, ten days with highs in the 70s, seven days with highs in the 60s, and one day with highs in the 50s.

The amount of rainfall that was received during each October plays a role in the temperatures of the month for each year. This October we have received an above normal amount of rain. In 2008, Tulsa only acquired 2.75" of rainfall in October. And in 2007 Tulsa received 3.04" of rain for the month of October.

What do you think the high temperatures will be for the rest of the month? Do you think high temperatures will remain in the 60s, or do you think we could still see some 70 degree days?

The rain keeps pouring down. So far for the month of September, we have experienced more rain than usual. To be exact, we have had 4.48" of rain above the average amount of 4.76". That brings our total rainfall to 8.29" for the month... and the month isn't even over yet! This past Monday, Tulsa was hit with 4.42" of rain! Although a significant number, the record for the most rainfall within a 24 hour period is 6.39" which occurred in 1940. Other days with significant amounts of rainfall this month were September 10th with 1.36" of rain, September 18th with 0.93" of rain, and September 9th with 0.58" of rain. Both September 3rd and 4th experienced rainfall totals around a quarter of an inch. With all this rainfall, our temperatures have been below normal this month. Today, high temperatures only reach 73 degrees in Tulsa which is 8 degrees below normal for the day! As a whole for the month, temperatures on average have been below normal by 4.65 degrees.

September is not the only month this year to experience higher than normal rainfall. February, March, April, May, and August all had rainfall totals above average. For the year so far, Tulsa has received 37.52" of rain which is 6" above normal!

The average amount of rainfall that Tulsa receives in a year is 42.42". If we have already received 37.52" of rain for 2009, do you think we receive more than the yearly average by the end of December? How much excess rainfall do you think we will receive? Only time will tell!

For all of you who tried to guess the number of 100 degree days for the summer... the results are in! And the answer is... there were 14 days with temperatures at or above 100 degrees this summer! That makes Dennis Campbell our winner! Also, the highest temperature recorded this summer was 102 degrees! Unfortunately, no one correctly guessed the hottest temperature.

In June we had five days in a row with temperatures at or above 100 degrees which tied a record. In July we had six days with temperatures at or above 100 degrees. Out of the six days, three of those days had a high temperature of 102 degrees. We only had 3 days where temperatures were at or above 100 degrees in August. Out of the three days, only one day was 102 degrees.

Thank you to everyone who participated. Stay tuned for winter predictions!
