Local Alert Weather Forecast, Tue., Dec. 1, 2015
A STAGNANT AIR ADVISORY IS IN EFFECT UNTIL WEDNESDAY AT 12PM.
A WINTER WEATHER ADVISORY IS IN EFFECT UNTIL WEDNESDAY AT 7AM.
Due to a passing storm system, there’s a good chance for freezing rain, sleet, light snow, and rain across the High Desert tonight. This is what prompted the winter weather advisory. Please use caution on the roads. Snow accumulation could be up to 1 inch. The biggest threat is related to ice and refreezing slush on the roads. Low temperatures tonight will dip down below freezing, but remain in the lower 20s due to the moisture and overcast skies.
A low pressure storm system is dragging a cold front, with a warm front right behind it. This will allow for us to see a wintry mix, but then remain in the 40s for the rest of the week. Due to warmer temperatures aloft and freezing temperatures at the surface tonight, we will likely see some freezing rain. The chances are much greater north of Redmond. Expect up to 1/10 of an inch total ice accumulation. This storm doesn’t really compare with our winter storm last week, but roads can still be dangerous.
Tomorrow’s high temperatures will be in the upper 30s and lower 40s. We will see light showers in the morning and cloudy conditions until later afternoon. Around sunset we could see some more steady rainfall, but not much in terms of wintry mix due to the fact that our overnight low temperatures will be mostly at or above freezing.
The extended forecast shows 40s and rain in our future. Despite the stagnant air advisory, we will see lots of vertical mixing of the air once the storm passes through. This will certainly bring an end to our stable air mass and improve air quality.
