T-storm and Wind potential today into tonight
The potential for a major weather event is occurring in the PNW today and tonight. Firstly, a “mini-front” will move through the area around noon, bring scattered spots of heavy precipitation. This will likely be followed by scattered heavy showers and maybe an isolated strike of lightning as we go through that afternoon hours. This is due to a large difference in temperature in the atmosphere.Now best chances for lightning are in the northern Oregon cascades, but we can’t completely rule it out elsewhere. Now, tonight the excitement begins. A large low pressure system will move up our coastline, with a strong pressure gradient on the southern side, so that is where strong winds will be. This could bring potentially damaging winds to the southern Washington and northern Oregon coast, 60-80 mph. It remains to be seen how much of this will track into the Puget Sound region, and Portland metro. Portland metro has decent model agreement of around a 50 mph gust. However, model agreement is less profound in the puget sound region, with great discrepancies showing in the models. Some models include gusts up to 60 and some only have gusts up to 40. Thanks for reading.
