Connection Between Siberian Strat Warming & Eastern Cold Next Weekend?

Written by on October 26, 2014 in United States of America with 0 Comments

Before we get to the potential fun and games of next weekend and threats of a frost, freeze and even snowstorm, we have MAJOR end of October heat over the Plains currently and it’s thanks to a strong storm driving into the Pacific Northwest.

The initial 500mb chart shows the trough deepening over the West Coast where it’s wet and wild but in turn it’s pumping the ridge further east.

Yep, the West Coast storm is pumping the ridge and temps to record levels on the Plains. Chilly over the Northeast but nowhere near on par with this time next weekend…

It’s that storm pushing into the Pacific Northwest now bringing it’s inches of rain, feet of snow and 100 mph winds and another piece of energy of the Bering Sea which the models have phasing, DEEPENING THE TROUGH IN THE EAST.

Check out the surface/upper charts for late week into next weekend.

Notice in the 500mb height anomaly charts how the PNW system crosses the northern tier and then suddenly deepens the trough in the East by 144 hrs.

Yep, model has 30 above normal on the Central Plains today but near 30 below normal next Sunday AM over parts of the Southeast.

ECMWF still shows interior East snow. A little more realistic compared with last night’s run!

The question I’m asking, is there a connection between the stratospheric warming in recent days over Siberia with this first winter blast into the Eastern US. Afterall the strat warming we did se last winter was over the same region and the coldest air was driven into the Midwest and East.
