There are a number of parts to looking at this summer. First we have a new tool available from NOAA (National Oceanic and Atmospheric Administration). This tool provides a local 3-month outlook by individual NWS weather station. This particular tool, which I have linked to from my main website, is showing an better chance at the summer being warm. This isn’t an unusual forecast for NOAA. They tend to be on the “everything is getting warmer” band wagon. However, their Climate Prediction Center is showing a chance for a wetter than average summer:

However, keep in mind my post from April 28, 2009 and the associated Intellicast article on the summer outlook. The Intellicast article takes into account several factors in analog years to predict the summer. Their prediction is towards a cooler summer. Unfortunately they level out a prediction for precipitation.

Usually, I like to look at the sea surface temperature anomaly in the waters that affect our precipitation. These would be the waters off the Baja Coast and the Gulf of Mexico. The Gulf of Mexico is fairly mild this year, so far. There is a body of warmer than normal water off the Baja, but there also appears to be a boundary of cooler water between us and there. In all, a wash for warm water driving more moisture to us.

So, in my mind, I think if we have cooler this summer, it could be wetter. If it is hotter, we could be drier.

I’ll be doing more about the Monsoon in the near future.
