115 of 90

2 PM Friday Update... We did it!  We are now tied for the most 90 degree days in a single year in Little Rock weather history. We will approach 90 through Monday and Tuesday which should put us well into 1st place.

We fell short of the record a few weeks ago and thought it probably wouldn't happen.  Now we have an October heat wave which could put us over the top.  If we hit 90 today, we will tie 1954 and 1980 for most 90 degree days in a single year.

Both computer models have us at 89 for a high Friday so it's going to be close, but I think there's a very good chance for hitting 90.  The airport is basically in a desert right now with a mix of a very dry ground and hot concrete.  The models have underestimated temperatures time and time again so why would today be different?  Dewpoints may come up a few degrees, but I don't think it's enough to have a real impact.

The two major models show a high Saturday of 90 and 91 which would put 2010 over the top.  Stay tuned today and Saturday for updates here and on twitter.

Todd-I think we will break the record. I still wonder how many days of 90 degree highs would of happened in 1954 and 1980 if we would of had the volume of concrete in structures that we have today. I think it made a great difference in breaking the record overall of highest average temp for a summer, because of those structures and runways holding the heat at night and causing the low temps to be higher.

Todd-I should have said 1954 and 1998. Saw Ninja's post under Arkansas Weather Bloggers.
