June Bugs

June bugs me sometimes---the heavy storms of summer almost always are slower to arrive than I'd like, and the tropicas are (usually) quiet. However this year may be an exception---some of the model forecasts for the Caribbean from June 5th on are quite rambunctious! June is a warm month here, although not usually very hot. However, last year we had our highest temperature in 8 years of records at my home station on June 14th! So you never know!

Usually, rainfall increases during June as the atmosphere begins to moisten and the seabreezes that push showers inland weakens (slightly). However, this year may be an exception, as last year was. Our drought is of such long duration, and I see nothing in the patterns that wants to break it.

May was hot and dry, with an official rainfall of 0.58", 2.11" below normal for the month. Our yearly deficit started at 5.00" below normal at the beginning of May, and deepened to 7.11" below normal at the end of May. Our rainfall deficit has been more than 60" since January 1, 2006. Last year was our driest on record, going back to 1948. We had rainfall of 24.27" in 2010, exactly 24" below normal. This year rainfall has been 9.67" so far, which is 1.37" less than last year on this date. Will we have a new driest year on record? It's beginning to be a serious possibility.

May was warmer than normal, although the departure was not as great as in April. May had an average temp of of 75.3 at KSSI, which is 1.6 degrees above normal. The highest temperature was 92 on May 21st and the lowest was 54 on May 5th and 18th. Two records were tied, none were broken.
