What is a good weather prediction site for CONUS for 3 months out?

[newbury]

In a thread last summer, https://www.tractorbynet.com/forums/rural-living/396885-what-good-long-term-weather.html, I asked for radar prediction sites and TBN turned up two I like and use frequently (Ventusky - Wind, Rain and Temperature Maps and Interactive Future Radar Forecast Next 12 to 72 Hours).

Now I'm asking for what is presently the best for general predictions of temp and precip for a few months in the future.

I had been relying on NWS CPC but it seems to be a bit off.

The map on the left is what was predicted on Dec 20th, and is still active in the above link. The map on the right is the prediction made Dec 31.


A fairly big change, where I had been looking at cooler than normal in the Southeast US it's now predicting normal.

At this writing, (0745 1/1/1991) it's 62 degrees out in DC, "normal" high for the day is 42. Thus when I had planned on relaxing in front of the TV for a "below normal temp" "holiday" my boss (me) will require me to go out and do vehicle maintenance.

So what are people using for weather prediction sites for CONUS for 3 months out?

thanks in advance

For 3 months out, I think these will be as accurate as anything else. Heck, in most cases they'd probably be better than the "forecasters" 3 days out...

They only do precipitation though, not temp.

Weather.com puts out a 3 month forecast periodically. It is usually about 80% wrong.

Beyond 72 hours is basically fantasy land stuff.

CPC uses certain indicators combined with data from past years.

I agree about "Fantasy Land" beyond 72 hours. Some models go out 240 Hours reflecting the statistical assumptions per model.

For the weather minded: Weather Links especially the resource section, and Weather Discussion and Discovery - WX Disco

So far this Winter season it appears that all the weather models are having difficulties with this highly energized Pacific with a split jet stream flow over the CONUS with no blocking Atlantic weather system pattern.

I enjoy reading the Old Farmer's Almanac.

Let's make a deal.

I will make a roulette wheel with entries like "above average temperatures," "below average temperatures," "above average rainfall," "below average rainfall," etc. We will periodically spin the wheel for me as a predictor of future weather in three months. You can consult whatever system you can find to predict weather 3 months out.

How much do you want to wager?
