Weather: The Right Coast

By Robert Korty
STAFF METEOROLOGIST -- The comedian Lewis Black once quipped that the best job in the world is to be the weatherperson in San Diego. Having just returned from a conference there, I see his point; the five day forecast called for sunshine and mild weather all week. In truth, though, forecasting weather on the west coast can be a difficult job. While we in New England benefit from a continent full of weather observations to our west, scant data are available from the Pacific Ocean either to meteorologists or to the weather models that forecast the evolution of the atmospheric flow. Weather models generally forecast systems over the eastern United States well a few days ahead of their development, though local shifts in wind, such as a sea breeze, still complicate the forecast, especially during spring.

A front pushed offshore last night, sweeping the cloudy weather of yesterday out to sea. Today will be sunny, warm, and windy as a tight pressure gradient will keep westerly winds strong through this evening. Saturday will be pleasant also, but a weak area of low pressure will bring the threat of rain back to southern New England on Sunday.
