An upper-level ridge of high pressure has been primarily centered over the middle of the nation in recent days and an occasional push to the northeast into the eastern Great Lakes.  This kind of pattern has allowed for a fairly consistent north-to-northwesterly flow of air in the upper part of the atmosphere over the northeastern states.  The result of this has been two-fold. First, it has kept the weather on the active side with numerous batches of showers and thunderstorms in recent weeks rotating around the outer periphery of the strong upper-level ridge from a NW-to-SE direction around here or even N-to-S. In fact, showers and thunderstorms are likely to move in this kind of direction from later today into Thursday in the Mid-Atlantic region with heavy rainfall on the table.  Another impact on the persistent northwest flow aloft has been as an inhibiting factor in the sustainability of in places like Washington, D.C., Philly, New York City and Boston.  As a matter of fact, there has been only one time this spring season with “back-to-back” days of 90 degrees or more in DC and Philadelphia and no such consecutive days in New York City. Boston has officially not even reached 90 degrees on a single occasion during the months of April, May or June.

The next several days are likely to see a continuation of this overall active weather pattern in this part of the nation with little chance of sustained heat. In fact, it appears as though another strong cold front will drop from northwest-to-southeast early next week paving the way for yet another cooler-than-normal air mass in the northeastern states as we end the month of June and a reinforcing shot is possible as we turn the calendar to July….perhaps around the for the 4th of July holiday weekend.
