Something called “PNA” or Pacific North American Teleconnection Pattern could have some answers for our current weather pattern that’s kept us in a dry trend over the Bay Area. While we often show the 7 day forecast, we are always looking well beyond that with different forecast models to see any changes in trends. “PNA” is all about the jet stream connection from near Japan to the United States and can help determine our Western weather trends. What we look for in “PNA” is a (+) positive phase, which can bring dry weather or (-) negative phase, which can bring wetter weather.

The good news, “PNA” is now showing signs it would trend more (-) and signal the return of more rain chances that could make it to the Bay Area. While it’s still too early on any totals, it does look like the mid to end of December may be looking up for us on rain chances. We’ll keep you updated in the weeks ahead.
