Wednesday the 20th marks the last day of Spring with naturally summer beginning Thursday. We'll have 14 1/2 to 15 hours of sunlight Thursday with the sunrise at 6:07 am and the sunset occurring at 8:44 pm. The solstice is when the northern hemisphere faces the sun and that will be the case for the next few months. With that angle to the sun, we'll have more very warm to hot temperatures.
Spring was pretty quiet weather-wise considering there were only 2 tornadoes in eastern Oklahoma and those were in Osage County on May 19th. Only 16 tornadoes were observed across central and western Oklahoma, which is way low for state averages. 15 of those twisters were on May 2nd with 1 in the morning of May 3rd.
In terms of heat, it really warmed up during the 2nd portion of spring. The 1st small part of late March it was cooler and then it was a mix of warm and cold in April. Then it really heated up in early May with the high reaching 90° for the first time on May 6th. In fact, May had an average high of 87° with the average high being 79° for the whole month. May ended up with 13 days of 90°+ highs.
When we arrived at June, it was full blown summer already with hot temperatures and endless humidity. So far, we have had 14 days of 90°+ highs with the highest afternoon high being 97° on June 14th.
Looking at the long range data for the entire summer into September, it appears that temperatures will be above average with equal chances for precipitation to be below average, at average, or above the average.
