Currently, mostly clear skies across western and central North Dakota. A weak, dry cold front has pushed through all but the far southeast portion of the state. Temperatures behind the front were in the lower 30s to mid 40s. A few areas of patchy fog were noted where temperature/dew point spread were close.

For today, high pressure slides east across the state. Generally light winds from the north will shift east to southeast through the day. Western ND will see some stronger southeast winds (around 15-20 mph) mid to late afternoon. Highs today will be just a bit cooler than Tuesday for most areas, but still well above normal. Lows tonight will range from the mid 30s to mid 40s.

Thursday and Friday will see the warmest temperatures of the week. Highs each day will range from the mid 70s to lower 80s, with warmest temperatures each day in the southwest.
