Summer Outlook

First of all, congratulations and best wishes to all the graduates. The weather will fortunately allow for outdoor celebrations today. Although it will be cloudy, rain should remain to our south until the evening hours. A coastal storm will scrape us tonight, but pleasant conditions for the weekend will follow.

Many of you will be traveling to other parts of the country this summer, and you might be wondering what to expect weather-wise. Over the last few weeks, a pattern has developed over the eastern Pacific Ocean, known by meteorologists as a Rex block. This Rex block consists of a high pressure system located directly poleward of low pressure. The two act together to “block” the normal eastward migration of weather systems, causing the flow to break into two branches that move around either side of the block. This general pattern is forecasted to hold over the next month or two, and will lead to a wet and cool California, anomalous warmth stretching from Arizona eastward to the Carolinas, and cool conditions over the northern Plains and Great Lakes states. Enjoy the summer!
