KEY MESSAGES

- Patchy frost is expected tonight across parts of northwest Minnesota, with lower chances in northeast North Dakota.

- Our next chance for precipitation will be Wednesday night into Thursday, then once more this weekend.

..Frost Possible Tonight into Tuesday Morning

Low temperatures tonight are expected to fall into the middle 30s to upper 30s, primarily in northwest Minnesota (60 percent chance), with a lower chance (20 percent) in the northern Red River Valley and far northeast North Dakota. Radiational cooling is expected to be efficient as winds go nearly calm tonight across the area. Dew points will generally be in the middle to upper 30s as well, thus limiting the floor of lower temps. Patchy ground fog could form in cooler spots around sunrise.
