Showers precede weekend cool-down
The Institute’s relatively rainy autumn continues today, as a low pressure system will develop and pass from west to east over southern New England. This storm will likely bring light to moderate rain showers to the Boston area throughout this afternoon and evening. Depending on its exact track, the frontal system could also bring another spike in temperatures: areas to the south of the center of the low will see temperatures in the upper 60s, while those to the north will remain in the 50s (°F). If the storm does pass to the north, a warmer afternoon with significantly less rain is possible.
This afternoon’s storm system could bring up to a half-inch of rainfall, continuing a relatively rainy trend that began around a month ago. The weather monitoring station atop the Green Building has measured 7.30 inches of rain since September 30th, compared to just 6.56
inches in the four months prior. The fall and winter months generally feature more precipitation than those in the summer, so more rainy weather will be needed to alleviate the current drought in Massachusetts.
After tomorrow’s storm moves out to sea, the sun will return for the weekend. However, temperatures will be kept a few degrees below normal by a brisk northerly wind on Friday, and by the presence of an upper-level trough on Saturday and Sunday.
