Large-Scale Weather Pattern Change Expected Next Week over the U.S. (Credit: Weather.com)

DISCUSSION: The south and central U.S. has experienced a relatively mild winter.  But that pattern broke last week when the central and eastern parts of the country experienced a cool down, culminating in the Nor’easter that impacted the northeast part of the country.  Next week, conditions are expected to go back to the way they have been most of the last couple months.  The graphic above shows the expected pattern of the jet stream (representative of the storm track).  A trough is expected over the west, while a ridge builds back over the central U.S.  This pattern will bring cooler and stormier weather back to the west coast, but these storms aren’t expected to be as intense as some of the January/February storms were.  This jet stream pattern will bring spring-like conditions back to the central U.S., including warmer temperatures and the chance of thunderstorms.
