Once upon a time, on a long-ago St. Patrick's Day, Gothamist had an early morning meteorology class. The professor, Dr. C, declared his disappointment that so many students are in a 9:30 a.m. class rather than out drinking green beer. He begins lecturing. Unlike his usual lectures this one is rambling and incoherent. The chalkboard illustrations Dr. C took so much pride in drawing are a mess. It soon dawns on the young weather geeks that Dr. C himself has already consumed more than a few Guinness for breakfast.

Irish eyes and a lot of sun are smiling on today's parade. Expect a high in the mid- to upper-60s. An afternoon sea breeze circulation will keep temperatures along the coast in the 50s. The temperature and sunshine pattern will continue through Saturday as a weak high pressure valiantly keeps a couple of cold fronts from advancing too far south.

One of those fronts will finally make progress on Sunday. Clouds will keep Sunday's high to the lower 60s. Rain, potentially heavy, arrives Sunday night or Monday. Daytime temperatures should return to the more seasonable lower 50s next week.
