Hello all.
As all of you may be aware.... some minor snow accumulations may be possible for pre-dawn Thursday and into early morning daylight hours.
The attached model is for 4pm Thurs showing the 24hr totals. Have also attached the 925mb map showing the weak low at 10pm Wed just off the NW WA coast.
This possible snow fall, though not so wide spread as for what is shown, will be due and area of low pressure swinging SW out of southern BC and over the WA coast by late tomorrow night. This low then appears to drop farther south and land over Oregon for
later Thurs as it weakens even more.
So the low should quickly fill in as it
comes inland. So while the snow chance may be possible, hard to say who will and wont get snow due to the nature of the low as it`ll be showery in nature. And if you notice in the 24hr totals, it gives a big ol` snow shadow across a swath of the Puget sound region. So between the 00zUW-NAM and UW WRF, you`ll have to take it for it`s worth as it gives different ideas on how it`ll play out. But any rate, it dose show colder air dropping over us LATE tomorrow into Thursday.
And despite a rather cold and near -40c lobe of area of cold air at 500mb moving down over Western WA by late in the day, I don`t see any surface or mid-level support for convection, but with cold air aloft, there could
be the ''one or two-hit'' wonder clap of thunder with quick
flash of lightning. Maybe even some ice pellets. But again,
no noticable support showing up for convetion.
So to sum up.....and if snows, it should be short lived as it appears we
warm back up the next day with highs probably near 50. So keep checking
those models!
Thanks Andy. It looks as if Olympia could get some snow.What do you think?
ReplyDeleteWell Brett...would say you have at least a chance, maybe a better chance as the low will be sinking southward as it moves down the WA coast. But again as I mentioned, it likely wont be wide spread and more scattered in nature.
