It’s notable that temperatures might drop below freezing Tuesday nigh; it’s still too early to plant some spring plants and flowers.

Temperatures moderate Thursday into Friday.

Another front moves through Saturday, but the showers associated with this front may not have upper air support, so little in the way of precipitation expected.

There appears to be a significant warm-up for the following week.
