Boston Weather: 41.0°F | A Few Clouds

Weather: A Chilly All Hallow’s Eve

By Greg Lawson
STAFF METEOROLOGIST

As October nears its end, the National Weather Service is publicizing that this will be the sixth driest October on record for Boston. The statistics are likewise for other New England cities. With less than an inch of rain for the month, it is has been so dry in fact that there is talk of a threat of brush fires, especially now that the foliage season is over and dry leaves are beginning to fall. Other October notables include the first snow of the season (a trace received on October 8) and still no temperatures below freezing yet, 35°F (2°C) is as cold as we’ve gotten.

Looking ahead, it does not seem that we will get any more precipitation nor any temps below freezing within October. We are currently under the shield of a large high pressure system which is slowly drifting eastward. Such systems disallow precipitation but tend to bring cooler air. Therefore, if you are planning on trick-or-treating tomorrow night, you should know that it will be fairly cold, expect temps in the low 40s F (5°-7°C). The high will then drift out to sea which will bring us southerly winds and a slow warming. Some models are calling for rain Thursday and possibly Friday, but I think it should remain dry. Expect wind and clouds though.
