What Does Winter Have Left…
A record cold storm has been bringing snow to Oregon today bringing record amounts for this time of year down to sea level in Eugene. That cold front will weaken as it approaches us tonight and we will be lucky to get a shower or two into Thursday.It does look like we could see a dusting to an inch or two up along the crest but nothing to really pay attention to.
The next trough will dig down off the coast by Friday and the low will spin off the coast slowly pushing inland. The models are still struggling with the timing of the precip making it into the basin. We may see the moisture streaming up from the South over CA to our West all day Saturday without pushing East. Eventually the front will push through by Sunday into Monday.
The Southerly direction of the winds will limit the orographic affects of the mountains and the precip will not be all that heavy. It looks like as the core of the low comes through Sunday night into Monday it may come through to our South. Right now snowfall amounts look to be around 3-6 inches Sunday into Monday at lake level with 6-9 inches above 7000 ft. and maybe up to a foot on the crest. Temperatures will be much colder with highs only in the 30′s on the mountains.
The next system will by diving in by next Wednesday but the Eastern Pacific ridge may be all the way out near 170w West of Hawaii. That may cause the ridge to try and build over Southern CA or just of the SoCal coast. The storm for Wednesday may stay mostly to our North with just some light snow. Some of the models suggest the storm crushes the ridge enough to get a moderate storm with amounts in the 6-12 inch range.
The ridge may shift East closer to 150w by the end of next week which would be a more favorable pattern for the next trough to dig further down the West Coast. We could see another moderate sized snow the weekend of the 31st. After that the ridge may start to build in off the coast. We’ll take another look at the weekend storm tomorrow night…BA
