A spotty thunderstorm yesterday afternoon and a few sprinkles after midnight have pushed this month's rainfall total to 9.81 inches. As is shown in the graph above, this month is now the third rainiest June on record. Less than half an inch more rain is needed to surpass 2003. For you weather stats geeks, notice that the long-term mean is nearly half an inch greater than the median. That's the nature of convective precipitation. Every once in a while June gets an extra thunderstorm or two and the extra rain from those storms pushes the average higher while not affecting the median. That perhaps accounts for why the last 30 years appears so much wetter than the 145-year average.
No rain is expected today or anytime until early next week. A shortwave passing overhead would love to produce a few clouds, but the Canadian high pressure system that moved in last night is not given the shortwave anything to work with. So, look for a sunny afternoon with a high in the upper 70s. Tomorrow's weather should be pretty much the same except right along the shore where a sea breeze will hold the temperature down a few degrees.
High pressure will remain in control through this first weekend of summer. We should see a slight warming trend, with highs on Friday and Saturday reaching near 80 and Sunday warming into lower 80s. The next significant chance of rain is Monday, and that's not looking all that promising just yet. Will the June rainfall total get stuck just below a new record?
