Jet Stream To Remain Zonal; Warm Spells To Come

The 12z 8-10 day 500mb height anomalies appear to be forming a consensus that would involve warm weather to affect much of the eastern US.

The tight lines drawn together on the Canada/US line appear to indicate the jet stream pattern and how it appears to be flowing zonally (on the US/Canada border). This zonal flow would keep the coldest air to the north and let the warm air flow freely down in the US.
However, this also does mean that any storm systems that come through into the southern Plains would remain there for a while, as there are no intense upper level winds to shift it away.

More to come.
