Today's update is presented by Allspeed Cyclery & Snow in Portland. Whether it is late-season deals on ski equipment, time for a new bike, or a tune-up on your current one, check them out at https://www.allspeed.com/  A WINTER WEATHER ADVISORY has been posted for most of the state ahead of the warm front that will move in overnight into Thursday. This is another PITA junk storm similar to what the region experienced over the weekend, bringing minor travel impacts. The boundary features all four precipitation food groups with snow at the onset, flipping to sleet, then to freezing rain, with rain showers as a parting gift.  A QUICK HIT OF SNOW overnight (west) into Thursday morning (north and east) could deliver 1"+/hour accumulation rates, which will be enough to slick up the roads and reduce visibility. COLD AIR DAMMING will again play a role in the outcome, bringing a period of icing to the higher elevations. This system has a track similar to the previous one but has more warm air to work with. The result will likely be SLEET/ICE PELLETS, as warm noses aloft appear more prevalent given the timing. This is where the bust potential is for snow accumulation and why the spread of 2-5" of total frozen precipitation is on the broader end. FREEZING RAIN (ICE) concerns are primarily in the higher elevations in the western mountains to the Central Highlands, where the cold air damming hangs on longer. I can't rule out isolated power outages, but the threat of that is very low. BREEZY conditions out of the south/southeast may gust in the 20-30 mph range, more noticeable for the shorelines and the north and east. THE REGION SITS IN THE WARM SECTOR after the junk passes northeast, and as a result, areas of DENSE FOG are possible in the afternoon into the early evening. A WEAK COLD FRONT passes through in the aftermath of the storm Thursday night. A crisp northwest wind is expected to develop behind the front, which will cause temperatures to drop to around freezing over the mountains and north by daylight Friday morning. Friday's high temperatures may be set around midnight as temperatures are expected to fall through the day. WEEKEND OUTLOOK: Another warm front approaches on Saturday, bringing rain showers to the coastal plain and another round of junk for the west and north starting late afternoon into the overnight. The wintry mix transitions to rain on Sunday morning. A chance of showers persists through Sunday, but it does not appear to be a washout. A cold front slowly passes through overnight into Monday morning. The PTW Weather Wall has the latest information... Your support is greatly appreciated!
