Cold Rain Maybe Snowflakes Ahead

March 10, 10 PM
After a cloudy start and only .10" rain overnight, the day cleared mostly out and we had a nice early spring day. Today was the first day that seemed to feel in sync with the calendar to me. Something about the sky - scattered puffy, benign cumulus covering over half the sky mixed with patches of blue, and the feel and look of the air really felt like a typical early spring day around here. The high was 53.

Now we are awaiting the next system and it is closing in on us, coming in from the NW. A deep low pressure associated with this is moving into SE Alaska, but the cold front is sliding south our way, with steep pressure gradients which will bring up the winds along the coast and north interior. We have a little breeze at the moment and the barometer is just beginning to fall, but ever so slightly. Tomorrow should be a rainy day for us, snow below the passes, and breezy. The front will move south and stall over western Washington and an interesting feature will be a wave forming over the front that will then move back north along the coast on Friday, causing an increase in rain and wind all over again. It appears to me to be something like being in a car wash where the wash mechanism moves from front to back over the car, then reverses and moves again from back to front over the same car. Looking forward to seeing how this all plays out.

A beautiful start to the day today as brief high pressure cleared the skies out overnight and this morning. Later clouds again gradually increased through the day, although they didn't seem very threatening and were slow to change. The low this morning dropped to a frosty 28 here and again the high was 51, but the majority of the day was spent in the 40's. Currently it is 39 at 8:00 PM.

A front is moving inland, but slowly and supposedly later tonight rain will push in this far. Heavier showers could mix snow down to the surface but no accumulation is expected outside of perhaps Hood Canal area. The front will pass before dawn tomorrow and then any idea of snow will just turn to cold rain showers until another brief ridge partially clears the skies for a few hours. I'm not expecting too much rain tonight. The next stronger system is heading in Wednesday night and lingering through Friday and again heavier showers could produce a rain/snow mix, or brief snow as the precipitation begins. The mountains could get a good dump of snow from this system and gusty winds could also be in the mix, as a deep low pressure is moving by offshore later this week. So, a cool and more active rest of the week seems to be shaping up for us.

We just heard from cousins in Bellingham and they are bracing for possible snow (they live to the east a ways). Sounds as if you are in to your typical spring pattern, huh? It has been snowing in SE AK, which is unusual this late in the year for them. Cold and dry for our area, but there have been some perdigious snows since last friday. Whittier in PWS has seen over 60" in that span. Hope you have a great weekend, anyway!
