Discussion

In the wake of Monday night’s frontal passage, a comfortable air mass pushed into the Mid-Atlantic region on Tuesday and it'll stay very pleasant around here for the next couple of days following the passage of a secondary cool front. Temperatures during the next couple of nights will drop well down in the 50’s in most suburban locations and afternoon highs will remain in the comfortable 70’s until Friday. At the same time we’re enjoying comfortable weather conditions in the Northeast US, much of the western US is suffering through some excessive heat as intense upper-level high pressure dominates that part of the nation. For example, Phoenix, AZ may experience high temperatures near the 120 degree mark later in the week and Death Valley, CA could reach 125 degrees. Elsewhere, it looks like the Gulf of Mexico will feature a tropical system by the end of the work week and this system should move northward towards the central Gulf coast by the late weekend. After that, there is a chance that the leftover rains of the tropical system move to the northeast and potentially all the way into the Mid-Atlantic/Northeast US during the early part of next week.
