Good late eveningto all.
As you can see by the current inferred satellite imagery, a frontal system is not to far off shore and the thinner clouds ahead of this system should be reaching the coast over the next few hours. This is the system that will be moving through during the day tomorrow(see attached 3hr precip chart for 11am) giving us rain and then showers at times once this system passes by tomorrow evening as a cold front. So expect another day with highs in the 40`s to around 50. Though as mentioned, rain will be added to the mix, so it will feel a bit cool.
Once this cold front slides on by tomorrow evening, this will usher in a brief but also a cooler/colder airmass into our region as a trough clips our region. And with flow aloft switching to the NW-NNW, could see a bit of the white stuff flying around the lowlands early Tue morning as both 850 and 925mb temps dip several degrees below freezing. But other wise, Tue should be a cool and showery day, but with possible sun breaks with unstable airmass in place Then for Wed, conditions look to dry out and flow becomes more NNWLY and showers appearing to decrease Wed morning from North to south. So Wed is looking to be a day of improving weather with what looks to be a dry day on Thurs under NNWLY flow along with weak surface and upper level ridging.
Hey Andy. What is the chance that on Wednesday morning we could get a little snow in Olympia. I know that it looks like it might be cold enough but could there be some showers rolling in that morning? Thanks.
ReplyDeleteBrett... hard to say what the chances are for you in terms of snow, but I would go with a small chance as the cold front with trough + NWLY flow, works through Western Wa during the day Wed. So could see a little snow, but right now, the area you mentioned looks to be mainly precip free. Airmass not even all that cold for Wed morning with 850mb temps showing -6, -7c and 925mb of -1, -2c over the lowlands. So if I had to take a take a stab at seeing snow, would for now say best chance would from central sound and points north as that cooler filters in.
ReplyDeleteBut also, the air/ moisture starts to dry up pretty fast and pretty much done with by early afternoon hours as precip ends from North to south. So keep checking the models. :o)
