A strong cold front will pass through the area Saturday afternoon into Saturday evening. Ahead of the front, high temperatures will surpass 80°. After the cold front moves east of the region, a reservoir of colder air will surge into the area Saturday night into Sunday.
After morning lows in the lower 50s (with some 40s in the mountains), temperatures will not rise much the rest of the day. Early afternoon temperatures will range from the mid/upper 40s in the mountains to about 50° to 55° for most other locations. A northerly breeze up to 15 or 20 mph will also make it feel a little colder.
The last time we saw a high temperature in the 50s was back in April. The record “cool” high for Sunday is 56° from 1935. The chances of tying or breaking it are not very high. The daily records are based from midnight to 11:59 p.m., and temperatures just after midnight Sunday morning will be in the upper 50s. However, we will see a temperature drop of 30° or more between Saturday afternoon and Sunday afternoon.
