Realistically only three of the next seven days will be nice, BUT it appears it will be the three that matter most; Saturday, Sunday and the 4th of July. (Granted at 6 days away the 4th isn't a lock yet, but still. Also of note, this pattern adheres to my life motto: You don't have to be consistently good, just awesome when it matters most).
That stubborn, pesky, annoying slow moving, notably unattractive (too much?) upper level low that's been around since Monday is still spinning to the northeast of Caribou. That's the bad news. The good news is that the low has become what we called "vertically stacked," which basically means the dynamics of the low are gone and it is rapidly weakening. As a result there will be substantially less shower activity today when compared to the past few days.
Look for a mixture of sun and clouds over much of the state with the most sunshine over southern Maine and New Hampshire and the least sunshine across northern Maine (closer to the low). Isolated showers will develop this afternoon with about a 10% chance of showers over southern Maine, 25% chance over central Maine and a 50% chance over northern and Downeast Maine. Any showers should be light and short lived. Meanwhile temperatures bounce into the upper 70s in most spots, with some low 80s in the sunnier locations.
Sprinkles fizzle with the setting sun (great name for a rock band) and give way to a partly cloudy evening. It should be pretty quiet and temperatures drop only into the upper 50s to low 60s.
Friday starts off with a good deal of sunshine but a cold front swings through in the afternoon producing a line of thunderstorms. The dynamics on this front look marginal so I'll keep an eye out for a few stronger storms, but my gut says it won't be an issue. Temperatures warm up into the low to mid 80s by the afternoon.
After that front pushes offshore on Friday night, the heat is on for the weekend.
A strong westerly wind will pump in warm air and allow most of the state to reach the upper 80s to low 90s. I'm going with a mixture of sun and clouds on both days because I'd LIKE to see a stronger sign of riding in the models. As it stands there is a weak trough signal along the coastline, which in the past, has led to some cloud development via weak instability. Computer models even indicate an isolated afternoon shower in the mountains Saturday afternoon...I buy that. All that said, it will be a great day for most of Maine and an awesome beach day with the west wind fighting back the sea breeze. (Chalk another one up to the "the day after a cold front is the best beach day" theory)
Sunday looks similar to Saturday in terms of setup. It should be a TAD cooler overall as the westerly wind settles down. Still warm though, upper 80s for most.
Looks like some showers for late Monday afternoon through Tuesday but I have high hopes that we will clear out in time for the 4th. Then again, I had high hopes I could bring back the term "tubular" ala 1990s Teenage Mutant Ninja Turtles and that hasn't worked out for me yet....
