Long Range Forecast: Jet Stream

Here's the week 1 (top) and week 2 (bottom) forecasts from the CFS v2 model for the jet stream. positive anomalies indicate a amplified jet stream, while blues represent a more subtle jet stream. For week 1, the US will be under a pretty de-amplified jet stream as it will be pushed further north into the Canada/US border, which is just out of the picture. The same story goes for week 2.

For week 3 (top) and week 4 (bottom), the colors are less intense as the forecast period and uncertainty grows. However, it is still reasonable to see that the jet stream will remain displaced north per the arrow directions.
