What a difference a month makes!

One month ago the 7th biggest snowstorm on record in Baltimore was blanketing the area with over 20″ of snow (21.1″ officially at BWI-Marshall).  Today, afternoon temperatures were flirting with 60°.  What a difference a month makes!  So, what changed over the last 30 days?  Simply put, the jet stream has flattened.  Typical of an El Nino pattern, the southern branch of the jet stream has flooded the continental U.S. with mild Pacific air.  Embedded in the southern branch of the jet a series of wet storms has been tracking from southern California to Texas to the gulf coast.  For snow lovers there is always the chance of a brief shot of cold air coinciding with one of the wet storms chugging east in the southern branch of the jet, but the key word is “patience”.  Long range forecasts from the global models indicate the pattern “may” change back to a colder set up around the beginning of February.  Stay tuned.
