What: A series of four to five medium to strong strength low pressure systems will affect the region Tuesday night through Sunday, resulting in periods of rain, breezy conditions at times, and snow above 5000-6000'. These are not expected to be very cold systems, but total new mountain snow at the higher elevations could reach […]
La Nina: We've been talking a lot about La Nina lately. The latest data updated just yesterday shows that the atmosphere is now "linked" (responding to) La Nina conditions. La Nina has three different strengths, each of which generally have different impacts across the Pacific Northwest and Western Oregon. The majority of data and models […]
This is time of year when the computer models can get a little goofy, due to the change of seasons and increased contrast between cold air to the north and warm air to the south. To no surprise, this morning's computer model data is all over the place. Therefore, the forecast over the next 7-10 […]
Storm system that's currently affecting the region is the coldest of the season so far. Scattered showers to about midnight with a rumble of thunder possible to about sunset. Isolated showers Monday morning. Snow levels tonight and Monday are expected to dip to around 3500', but by then most of the precipitation will have fallen. […]
Night/morning fog remains possible again tonight and Friday morning, but frost is not expected. There'll be a slow increase of mainly high clouds overnight ahead of the next weak storm system that may bring some light showers to the area later Friday afternoon to early night (but don't hold your breath). Very light winds may […]

Early September started off dry, but we quickly made up for it with last weekend's storm. A couple of low pressure systems will bring periods of rain and showers to the region Sunday through Tuesday. Unlike last weekend's system, these storms will have a little less moisture to work. Therefore, rainfall totals are expected to […]
