If It's Friday It Must Be Raining

Sometimes the atmosphere gets stuck in a rut. The typical size and speed of high and low pressure systems means they should pass through the northeastern U.S. every few days. The pattern would rarely be noticed should it rain every five days as that would mean rain today, next Wednesday and the Monday after that. But when the repeat button is set for every seven days and the rainy days turn out to be Friday and Saturday people take notice.

Once again this weekend we have the same weather situation as last weekend and the weekend before. A low pressure system moving in from the west is running up against a cold front stalled just to our south to bring us a cool and rainy day today. The high may reach the upper-50s this afternoon, which is nearly 15 degrees below normal.

The rain should end early this evening and tomorrow should start dry. There's a slight chance of showers in the afternoon and the high will be around 70 degrees. Sunday is expected to be a couple of degrees cooler with a continued slight chance of showers. The start of the next work week is, of course, expected to be sunny. And if you are dreading another rainy weekend next week, the Weather Channel's ten-day forecast says next weekend will be mostly sunny with highs in the mid-70s.
