Three Progressive Back-to-Back Troughs This Week Featured

The weather will cool off and perhaps even bring rain or snow later this week.


Big Idea

  • Cloudy skies and breezy conditions this week
  • Could have some precipitation towards the end of the week
  • Temps in the mid 50’s dropping to 40’s on Sunday
  •


Forecast Summary:


Periods of partly cloudy to mostly cloudy skies and breezy conditions this week on Tuesday afternoon to Wednesday, then again on Thursday afternoon to Friday, and yet again on Saturday night to Sunday.  A chance of light rain showers on Friday, and a chance of rain or wet snow on Sunday. Snow accumulation, if any, on Sunday will be light, 0-2 inches, with slightly higher amounts possible in the higher elevations around town.


High temperatures will be in the mid 50s to near 60 today through Saturday, dropping into the upper 40s on Sunday. Morning lows in the 30s.

Three progressive back-to-back troughs will move through the area this week, each one progressively stronger. The first trough will bring mainly high clouds and some breezes this afternoon through Wednesday. The second trough will bring more clouds and breezes on Thursday afternoon – Friday, with slightly cooler temperatures and a chance for light rain showers. The third trough for Saturday night – Sunday will tap into sufficient moisture and cool air for more widespread precipitation across the state on Sunday. Snow levels will drop to between 5,000’ and 5,500’ on Sunday, leading to the possibility for some wet snow accumulation, especially in the heavier showers. Snow accumulation, if any, will be light (0-2”), with higher amounts possible in the higher elevations around town.


Total precipitation amounts for the week will range between 0.25” and 0.50” liquid water equivalent through next Monday.


The big weather story for the next week or two will be the abnormally cold weather expected over most of the Central U.S., with temperatures dropping well below 0 F in some places.
