A rather wet and muggy day is in store for southern and central Maine today as warmer and more humid air to the south attempts to move north and clashes with the cooler marine air now over the region. This is going to be one of those days when it’s just cloudy at times and then you get a downpour and then it’s drizzling and then it’s cloudy again. The amount of rain should generally close to an inch, but if your area sees some heavier downpours those amounts will become higher.

There won’t be any flooding with this rain (except perhaps some street flooding) and while you could hear some thunder over York County no severe weather is part of this system for our region.
The timing on the showers is such that they will increase in coverage during the day and be most numerous this afternoon. The morning is definitely the driest part of the day.

To our south, the Red Sox are playing this evening and with some rain delays they still could get the game played, but I’ll have a better idea on this later this afternoon when we see how far north those showers have actually moved. The rain I am expecting here this afternoon is occurring over Fenway Park the first half of the day.

The weekend is a very tough forecast for two major reasons. First, the front and associated showers moving east tomorrow has the potential to slow enough to keep showers and clouds in the forecast all day. The most likely areas for this to happen would be east of the Maine Turnpike. The further west you live, the better opportunity for sunshine.

Right now, I am forecasting clearing to push into the Portland area during the afternoon. However, there is a chance, let’s give it about 40%, that the clouds linger all day and even the risk of showers. Highs tomorrow will get back into the 70s, but we likely won’t see any 80 degree readings this weekend.

I’ll be updating the forecast @growingwisdom on Twitter.

Second is the forecast for Sunday. As the front does push off the coast a storm, just like a mini nor’easter is forecast to form on the front. The European model has this storm close enough to bring clouds and rain to eastern New England for Sunday. The GFS also has the storm, but keeps it just far enough east to spare us a wet day, and leave us in the sunshine.

Right now I am keeping Sunday a great day with abundant sunshine and highs in the 70s. If other models come in line with the Euro this afternoon, this forecast is going to make a 180 degree turn.
So what should you do? I will update the forecast later this afternoon and evening and give you an idea on what might change for Sunday. I am hoping the rain for Sunday is just a blip on the model cycle, but wishcasting doesn’t work too well.

Not that you’ll see it, but there is a full moon tonight which is of course Friday the 13th. We don’t have another full moon on a Friday the 13th until 2049. I shudder to think how old I’ll be by then!
