July is number 2
(Clinton) -- July was historically HOT and DRY
July 2012 will be in the weather record book as the second hottest and second driest in Clinton weather history back to the late 1870’s.
Clinton area official weather observer Jim Blaess says the overall average for the month was 81.4 degrees. He says that is ‘a half a degree’ below July 1936. The normal average for July is about 75 degrees.
There were five days with temperatures at 100 or above. Blaess says that is the most 100 or above days since August 1936 when there were six.
Two of those days set records. Blaess says the 103 on July 7th tied the record from 1936. He says that was also the highest temperature since July 25 in 1940 when it was 105. The 101 on July 18th broke the record of 100 set on the date in 1936.
There were 19 days with temperatures at 90 or above – and that includes the five 100 degree days – and the most in a July since 1936 when there were 22. The normal is six days. Blaess says in the May through July period there have been 30 days at 90 or above and that compares to the normal May through September period with 15 days.
The last significant rain was in early May according to Blaess. He says since May 7th the total precipitation is about 2.2 inches (over the 86 days to Wednesday).
Precipitation for the month was .33 inches or a third of an inch of rain. Blaess says that is second on the list dating to 1878. The driest is July 1991 when there was just over a tenth of an inch of rain. The normal rain fall in July is nearly 3.7 inches.
For the year-to-date precipitation, Blaess says there has been about 13.6 inches and that is about 6.3 inches behind the normal for the first seven months of year.
In August the normal rain fall is about 4.6 inches, but Blaess says it would take nearly eleven inches of rain to get the normal for the year.
There are typically four days with 90 or above temperatures in August. Blaess did say the average temperature does drop in August from a high of 85 and low of 64 on the first to averages of 81 and 59 by August 31st.
