Cloudy and Cool

I know that winter is getting old for many of us, so I thought I’d take another look at the Coupled Forecast System model forecast for the summer weather across the United States, which is something that I did back in January (Early Summer 2010 Forecast–Very Early).

The general forecast for June through August is similar to the original, with cooler- and wetter-than-normal weather predicted for much of the United States.

Remember, this is no forecast by a meteorologist; this is merely one of the tools that government (and private) meteorologists will use to create their official long-range forecasts.

Temperatures

The exceptions to the below-average temperature forecast remain New England, southern Florida, South Texas, and the West Coast, with the coolest air (relative to average) being forecast in the middle of the country.

Precipitation

The wettest weather (compared to average) is forecast in the Midwest and parts of the Deep South, with the exception of South Texas. While western areas are forecast for more precipitation than normal, this may not mean much–so little precipitation falls in this region during the summer that the actual amount of rain will most likely still be negligible.
