The Rain Train Rolls On…
The winter of 2010/2011 is just about over according to the calendar. However, looking at the next seven days it appears as though mother nature is going to keep the weather around here wet and windy. Although this past winter’s La Nina continues, it has weakened some. The PDO (Pacific Decadal Oscillation) figure for February was released today. It is still in the negative “zone.” This is about where I would expect to see it at this time of the year, coming off of a La Nina and considering the jet stream pattern over the past 3-4 months. This is all typical of the current ENSO (El Nino / La Nina) cycle. Seasonal forecast models are showing that we will likely stay in the La Nina to Neutral “zone” over the next 6-9 months. Thus, there is a greater than normal chance that we will see cooler and wetter than normal conditions continue this spring. But not all of the spring’s in the past (that fit this year’s mold) have been cold and wet. However, the odds are leaning that way for now. Wet is the word of the day! Such has been the case for the better part of the last 9-10 months, minus the typically dry summer months of July and August.
Speaking of “wet,” it looks like one system after another will be sliding through the Pacific northwest every few days over the coming week. The system on tap for mid week looks pretty juicy as well as windy along the coast. Another system will slide in through the area near the end of the of the week and yet another over the weekend. Normal daytime high temperatures for this time of the year are in the lower to mid 50’s. We will be lucky if we reach “normal” over the coming week. I certainly do not see any big ridge of high pressure in the coming week either. Don’t forget that this coming weekend is when we move our clocks ahead by one hour. I always enjoy this time of the year because I can actually get the lawn mowed after dinner, if need be. By the way, I have noticed that many of the area trees appear to be behind schedule with their budding this year. Perhaps the past 10 months being cold and wet, a record cold summer last year, an early season November freeze and late season snowfalls and freezes in February are all part of the equation? I suspect that to be the case.
Well, that is the latest for now. Stay dry and stay warm. Summer will be here before you know it. For some folks, it can’t come soon enough.
