PIECING THE PUZZLE TOGETHER...
After a little hint of spring in our temperatures the past few days it looks as if we are heading into a period where readings will average near to below normal the next 14 days.The EURO has this for highs and lows. Only a couple days above freezing and a bunch more in the 20s.
The downward trend (if it does indeed materialize) would be the direct result of the EPO (eastern Pacific oscillation) trending negative. Notice how since early December that teleconnection has remained largely positive.
Over the past 60 days (2 months) the positive EPO has been associated to temperature departures running 4-8 degrees above normal.
It makes sense when you look at the type of jet stream flow the positive EPO brings. With a strong trough over Alaska it's kept the flow aloft coming consistently off the Pacific. That seeds the U.S. with mild oceanic air mas
