GFS and Nogaps weather models


The following links are worthy of a bookmarking. The GFS model shows another possible drenching on Tuesday.


NoGaps weather model




GFS weather model


They go out to a 180 hour forecast, and are darn accurate to about 48 hours.

Hope these are of use. If anyone else has similar or better links, please share.

Drenching might be overstatement. Everything I've read and heard indicates that what's upcoming will be nowhere near as powerful as what we just experienced. I'm hoping they're right.

I hope it is an overstatement. The GFS model having the dark green and light blue is similar to what it was predicting last week, but forecast to be only one event of shorer duration versus 4 events over 5 days of last week.

If the GFS is right it looks like another fairly big storm. Aimed right at SoCal and Baja Norte

The Two Links Appear to Be Identical


Please help out a confused viewer and explain the difference between the two (pretend that you are talking to a child).

Thanks, the links are awesome and I say that in the true meaning of the word.

More Weather Commentary


"The jet stream that is going to hit Southern California is as powerful as has ever been recorded on this planet before, over 230 mph. The jet is at an extremely unusually low altitude, not 30,000 to 60,000 feet, but coming as low as 8,000 feet. This jet will be traveling over the unusually warm El Nino waters of the eastern pacific, and will be carrying freakish amounts of energy and moisture. A huge series of storms is going to slam into Los Angeles and the surrounding areas just one after another for day after day for up to two weeks.

The initial storms will be very cold, with snow levels as low as 3,000 feet. Heavy rain and snow will be hitting California from San Diego to Eureka. Next week, the driest places will see at least 3 inches of rain, the Los Angeles basin and northern parts of the county andVentura will see 6 to 10 inches. The wettest areas and cells within the system will hit with up to 20 inches of rain. Snowfall in the Sierras will be measured in the TENS of feet. Powerful winds will be associated with this storm--like a powerful Santa Ana but blowing in the opposite direction, west to east. Gusts up to 80 mph are forecast. But it gets worse. For the first time that I'm aware of, ALL of the various models are in agreement about the second week of the storm. Normally, beyond a week, the models diverge. But due to the extreme strength of the weather producing factors, this time all of the models produce the same results for the 8-14 day period. For the week of the 24th, we will be hit with a powerful and WARM series of storms, as strong as any we've seen. This heavy warm rainfall will fall onto the newly laid snowpack and what will be totally saturated ground, especially in the burn areas of LA and will produce tremendous melting and runoff, and the potential for record flooding. Due to the low altitude of the jet stream, 200+ mph winds will slam directly into the Sierras, producing tornado strength winds over a 200 mile wide front. DON'T head to Mammoth for skiing when you hear about the huge snow fall in the first week. A friend of Scott's is a Navy weather forecaster and he told Scott that the military is moving assets east out of the way ahead of this storm. Planes and helicopters are migrating out of the coastal bases and into the interior bases of Arizona and Nevada. They're taking this very seriously. This may sound alarmist, but websites I check related to weather modeling are using the word "Biblical" for this system."

The links are computer model forecasts. The more similar they are, the higher likelyhood that they are right. They start out very similar but diverge as the hours and days play out. To see a difference between the two, look at Tuesday 18:00 on the Nogaps, then Tuesday 18:00 on the GFS model . You will then notice a difference.
The GFS has a pretty potent storm over the area, the Nogaps disagrees.

Thanks For the Info


Does anyone have a biblical connection to Noah?

Or a lifeline?

Gypsy Jan, have a link to the quote above? Interested to learn more.

Also, the 10 day forecast only lists 1 day of rain, and thats not until Feb 1st.

The NoGaps still says the rain if any will stay north of the border on Wednesday.
The GFS is not quite so optimistic.

Jan,
What is your source for this forecast? That's the scariest forecast I have ever seen. I'm trying to decide whether to stay home, go to Mulege or just sit in my boat and wait for the Prophesy to materialize. :?:

I must apologize for having not noticed that the clickys that I recommended be bookmarked by those interested in computer forcast models do not update frequently.

Today is Thursday, and the Nogaps model has not been updated since Monday. Unacceptable. The GFS model is now over 24 hours old as well.

Here is a link to a GFS model that appears to update 4 times a day from Noaa. It is not quite as clear as the UW links, and is a Mercator map which removes the curvature of the earth.



It is claiming a rain event for S. Cal and Baja Norte on the day before Superbowl Sunday. It will be interesting to see the accuracy of a 10 day computer model forecast.
