Summary: The secondary coastal low pressure system developing along the passing cold front is tracking closer to Berkshire County than originally anticipated. Therefore, rainfall will be heavier this evening and rainfall totals will likely reach or exceed 0.50 inches. There may be a few lingering light showers overnight and again in the early morning as the upper-level low tracks over the region. High pressure will then build into the region for Tuesday through Thursday and we will experience dry and fairly clear weather for that period. It will be cooler on Tuesday as the winds blow from the northwest in advance of the high and it will then warm up on Wednesday and Thursday as the high tracks to our east and the return flow around the high brings milder air in from the southwest (note: wind flows clockwise around high pressure in the Northern Hemisphere). The next cold front will approach the region with another round of rain or showers for Thursday night into Friday.

Monday Night

Rain, moderate to heavy at times through the evening hours. The steadiest rain should end by midnight. There is the chance of a few lingering light showers after midnight. Probability of precipitation 100%. Total rainfall for this event will likely reach or exceed 0.50 inches. It will be overcast for most of the night but there may be some partial clearing toward daybreak.

Temperatures and dewpoints will drop significantly after the cold front passes with low temperatures reaching the low to mid 40s countywide by morning.

South-southwesterly winds will shift to northwesterly after midnight as the front passes. Wind speeds will average 8-12 mph.

Tuesday

Mostly cloudy during the morning with a chance of scattered light rain showers. There may be some snowflakes mixed in, particularly at the higher elevations. Probability of precipitation 30%. Precipitation totals less than 0.05 inches. Skies will clear during the afternoon, becoming mostly sunny by mid afternoon. It will be very breezy and cooler.
