Forecast: Freezing fog follows frosty front

A Cold front is expected to bring freezing fog to the region, before a warm up this weekend and chances for accumulations Sunday night

  • The first part of Thursday should be relatively sunny and cool, temperatures reaching the 30s and possibly 40s.
  • Before we can reach our full potential for the day, a cold front will push through something late this morning into the late afternoon and bring the chance for freezing fog this evening.

  • Most of this fog will be prevalent in the Northern and Eastern foothills, with a cool northerly breeze to follow as well.
  • A slight freezing drizzle could be possible as well, but not noticeable precipitation is expected with this front.

  • Fog and freezing fog will begin to creep into the higher elevations of the Black Hills and areas out in the Great plains as well.
  • Visibility could drop to less than 1/4 of a mile, and roads could become slick – particularly on bridges and overpasses.

  • Friday morning will feature lingering areas of freezing fog in the Northern and Eastern Foothills, and possible on the lee side of the Western Hills in Newcastle and Sundance, Wyoming.
  • By late morning and afternoon most fog will have mixed out, bringing temperatures back into the low 40s and 30s across the region.

  • Friday night is expected to be clear and cool, with some slightly warmer temperatures on Saturday – possibly creeping to the 50° mark with downslope westerly winds along the Northern and Eastern foothills.
  • First part of Sunday also looks pretty good, with increasing clouds and a cold front eventually crossing the region in the afternoon and evening hours.

  • So far, long range models have light accumulations possible across the region Sunday night into Monday.
  • Some moderate bands may be possible, but most should only see a couple inches of snow, perhaps even less.

  • A polar air mass is expected to plunge into the Northern Plains, clipping the Black Hills.
  • Although we will see colder temperatures, most of the colder air will be East of the Black Hills, particularly East River and going into Minnesota and Wisconsin.

DISCUSSION

Other than tonight’s foggy weather and the chance for light snow Sunday night, rather quite weather is expected this next week. Colder temperatures do look likely next week, before recovering back into the 30s and 40s by late next week. Travel plans towards Minnesota and Iowa should be watched carefully this weekend going into next week, as a fiarly decent system could cause a few travel delays. Stay warm today, as a brisk northerly wind will cross our area soon! – Brant
