Massive Storm Will Affect Our Weather

The remnants of Typhoon Megi are going to get caught up in the westerly flow, cross the Pacific Ocean and Slam the coast of Washington State. This is a very large storm packing extremely high winds and lots of moisture. Here is a look at the storm as it approaches the Pacific Northwest on Saturday evening:



If you have not seen these weather maps that I post, you can make out the Northern West Coast of the US on the right side of the image. Northern California is in the lower right corner.

This storm will impact our weather this weekend. The NWS is calling for 1.5-3.0 inches of rain along the north shore of Lake Tahoe. Some of this rain will spill into the valley adding to our already record amount for October. Here is the GFS precipitation forecast. GFS is calling for lesser amounts in our area. The NWS gets there information mostly from the EC model:


GFS has about 1/2 to 3/4 of inch of rain for Lake Tahoe and perhaps a 1/4 inch for Reno. Any snow associated with this very warm storm, will be confined to very high elevations, 10,000 feet or so.

Looking ahead, which is what this blog does, look for much cooler, unstable weather for at least the next couple of weeks. A series of storms appears to be headed our way. We could see some significant precipitation with a much cooler storm Halloween weekend. For Halloween day, expect a high in the upper 40's under party cloudy skies.

I will keep an eye on the next storm which should come in Thursday the 28th and last through the 30th. Right now GFS has that storm hitting us. The final graphic is a weather forecast for early Saturday morning, October 30th:



Stay Tuned ...
