A fast moving storm will drop in from the northwest overnight. It is not a big storm. But, it still has the potential to bring a wintry mix of rain or snow to the Treasure Valley just in time for the morning commute. Otherwise, look for a mixture of clouds and sun Wednesday. This front will generate snow in the mountains. We could see accumulations of 2-5” with up to 10” of snow possible in some areas by the end of the day at the higher elevations.
After the front moves through, high pressure will begin to build into the area on Thursday. Another fast moving disturbance could bring a few clouds to the region on Friday. But, after that, the pattern looks really dry Saturday, Sunday and through the first of next week. We’ll see mostly sunny skies this weekend with highs in the 40’s! Yes, that is warmer than normal by a few degrees.
Please note the WINTER WEATHER ADVISORY below for our northern mountains:
...SNOWFALL EXPECTED IN THE IDAHO CENTRAL MOUNTAINS TONIGHT
.A warm front with an ample moisture tap is expected to move
through tonight through tomorrow. This will cause a roughly 24
hour period of snowfall in the Idaho Central Mountains, impacting
travel and roads. Snow ratios are expected to decrease as
Wednesday wears on, so a lighter fluffy snow will be replaced with
a wet and heavier snowfall by mid day Wednesday.
...WINTER WEATHER ADVISORY IN EFFECT FROM 5 PM THIS AFTERNOON TO
5 PM WEDNESDAY...
* WHAT...Snow expected. Total accumulations of 2 to 5 inches,
with localized amounts up to 11 inches, are expected. Plan on
slippery road conditions.
* WHERE...West Central Mountains and Upper Weiser River zones.
This includes the towns of Cascade, McCall, New Meadows,
Council, Cambridge, and surrounding areas. Roads impacted
include Highways 55 and 95.
* WHEN...From 5 PM this afternoon to 5 PM MST Wednesday.
* ADDITIONAL DETAILS...Be prepared for reduced visibilities and
difficult travel at times.
A Winter Weather Advisory for snow means periods of snow will
cause primarily travel difficulties. Be prepared for snow covered
roads and limited visibilities, and use caution while driving.
The latest road conditions can be obtained by calling 5 1 1.
