Bridgewater - " For February, we got around one inch of snow which is much below normal. We usually get around six inches for this month. My cutoff day for any measurable snow is April 15. What a contrast from last winter's snows. In the past, we have had some big snows in March. There were a number of forest fires in this area during the later part of the month. There was quite a bit of property damage but no injuries . On several days, the conditions were just right for fires with low humidity, a dry ground, and very high winds. One day the humidity was 13% and that is very low. The weather for February was very boring. Maybe March will be more exciting. " - [ + - ] - additional notes from Clayton
