The low temperatures are a result of a high pressure system bringing drier and cooler weather, the NWS said. The high pressure will move east of the area on Saturday.
That frost is expected to clear again by 9 a.m. on Saturday, and skies will again be partly sunny, with clouds starting to build back up as the day goes on. Temperatures will rise to a high near 63 degrees.
Saturday night will be mostly cloudy and still cold, though not quite as cold as the previous two nights, with a low of around 47 degrees.
For Sunday, the NWS forecast partly cloudy skies, with a chance of rain beginning in the early afternoon and carrying on through the night. Temperatures will rise to around 65 degrees during the day before falling to around 43 degrees at night.
As the new week kicks off things could get wet as multiple rounds of showers are possible during the first half of the week.
