Local Alert Weather Forecast, Mon., Nov. 30, 2015, 7:45 AM
AIR STAGNATION ADVISORY IN EFFECT UNTIL WEDNESDAY AT NOON
Hello and happy Monday everyone! We are finally starting to get above freezing for our daytime high temperatures. There are some concerns, however, regarding our air quality. Due to our stable air and lack of winds, we have an Air Stagnation Advisory until December 2nd of this week. This means that our air quality will start to deteriorate as air pollution stays at the lower levels due to our stable air mass hovering above us.
A low pressure storm system is getting ready to hit Central Oregon. This will arrive mostly likely by late tomorrow night. This would absolutely improve our air quality because it would provide a lot of vertical mixing of the air. It would also bring rain showers to our region, with the possibility of some light freezing rain early Wednesday morning. I’m tracking the greatest chance of freezing rain to be south of Redmond. We will continue to track this and update you as we see any changes.
Tomorrow’s high temperatures will be in the lower to mid 40s with increasing clouds throughout the day. The best chance for showers tomorrow appears to be after 10PM, so most of the day will be dry. Showers will continue through Wednesday and into Thursday morning.
The extended forecast reveals a chance of showers throughout the week. We will see temperatures in the 40s for the entire week and into the weekend. My concern is with slosh on the roads causing driving conditions to be slippery. There’s a chance some of the slush could refreeze, but I expect black top roads to be a little warmer to prevent a lot of that from happening.
