Discussion

There are two big weather stories unfolding for the week and weekend in the Mid-Atlantic region with the potential of some heavy rainfall from later tomorrow into Thursday from the remains of tropical system Barry and then the hottest weather of the summer so far for the Friday, Saturday, Sunday time frame and perhaps even lasting into the early part of next week. Showers and thunderstorms are likely from later Wednesday into Thursday in the DC-to-Philly-to-NYC corridor mainly as a result of the remains of what was once Hurricane Barry and some of this rain can be heavy at times. Once this large tropical moisture field pushes away, the excessive heat will become the main story with upper 90’s possible for highs on Friday, Saturday and Sunday and triple digit highs are certainly on the table.
