No Rain

It’s been a long time since things seemed so dry outside. And the current extended range forecasts keep thing dry for us over the next two weeks!

Yes, there will be two cold fronts moving through this week. The first one will result in a familiar pattern of having any rain shear off to the far north and west of the city—

Today’s ECMWF shows showers only far north of the city. (Click on image for a larger view.)

Another cold front moves through Saturday. The models had been forecasting some light showers for us, but those have all but disappeared in the forecast—

Today’s GFS forecast for Saturday. Grey black is cloud cover. Essentially no rain with this front. (Click on image for a larger view.)

I’m still playing with the highly experimental AI-Machine Learning version of the GFS. It still seems to show the first chance of any substantial rain here is November 3rd!

All I can say is “Wow”.
