Wednesday Update - We did indeed get a nice little summer-y break yesterday, but today we'll be filling in parts of the tri-state with the showers. I wanted to thank all of you who sent in "blue moon" pictures-- here's one from Roane County (credit: Amy Whited)...
Now that we're in the 'fog season', it'll be much harder to see the moon toward dawn than it is during the evening. Today we'll amp up the tropical feel to the skies and watch for scattered showers and storms, but over-all it's still a garden-variety thing. No severe weather is expected.
Good Tuesday morning everyone!
Scattered showers and fog came across our region yesterday, followed by a breakout of sunshine for the second-half of the day. Today continues on that theme, trying to shove showers far enough to the south for a dry one. There's still a bunch of near-surface moisture hanging around, so expect some more morning fog to start the day. Here's the scene for the next two afternoons:

By mid-week we'll see a return of scattered showers to a good chunk of the tri-state courtesy of a passing disturbance (vorticity maximum) aloft. They always agitate the air as they move so this result stands to reason.
A "Blue Moon" or Not?
I thought this might be a good time to bring up something I learned recently, in case you find yourself outside doing a little stargazing. When the moon rises tonight, it will be full. It will be the first full moon of the month, but at the same time it still will qualify as a "Blue Moon". Apparently a second (or perhaps the more accurate definition) of a "Blue Moon" is the third full moon of four in a three month season. Most of the time this ends up involving a full moon showing up twice in a month. The last time a "Blue Moon" happened this way was back in November of 2010. For a more detailed (and interesting) explanation about how all of this came about, check out this link. Hint: It invokes the pages of the now defunct Maine Farmer's Almanac more than 75 years ago.
Sunshine will make appearances in each of the next several days, and even though the every-other-day pattern of scattered showers will hold, several hours of each day remains dry. These scattered showers (eg., Wednesday, Friday) will end up being the limiting factor in keeping temperatures below seasonable levels, with the other days making a run at the unusually elusive "above normal" range. We were talking about this yesterday, but the weekend has been coming into better focus with the increasingly favored solution being that of sunshine.
GFS - 700mb Chart - Saturday and Sunday
The models are now aligning in the projection of cloud-level humidity at 10% or less. That, my friends, is a sunny disposition. :-)
As you see in the 7-day below though, anyone lining up those outdoor plans should be ready with the sunscreen and the summer-weather precautions. The 90-degree mark is in range!
Have a great day everyone!
