After a chilly start to your Halloween, expect cool high temperatures in the low 60s. I think the morning clouds that have arrived will back off this afternoon, then they will stream back toward evening. Regardless of clouds, no rain is expected. Trick-Or-Treating conditions should be dry and a bit cool. By 5:00 PM, we'll be in the upper 50s to around 60°. Temperatures will fall into the upper 40s by 9:00 PM.
Your Halloween weekend forecast does get a bit tricky if you're headed to the mountains this weekend. A strong system will dive into the mountains from the northwest. At the same time, coastal storm is developing and strengthening. The most significant impacts from the storm will be felt along the coastline with winds and waves. A gale warning is up for the bay Saturday afternoon through Sunday morning. It's NOT going to be a good boating weekend!
In Richmond, we can expect a cloudy, breezy Saturday. Highs will only climb into the low 50s. Periods of mainly light rain are possible, especially later in the day. But most areas will be either dry or only getting LIGHT rain.
As the coastal storm pulls away, conditions will improve for Sunday. Expect a mostly sunny, windy, and cool day. Highs will be in the low 50s.
Not only will our high temperatures be cooler-than-average through the weekend, we're looking at a series of very cool mornings. Sunday morning's temperatures will be in the mid 30s. By the time we wake up on Monday morning, we'll be near 30. Traditionally cooler spots may make it into the upper 20s.
A modest warming trend will kick off Monday afternoon.
