Showers mark the end of our latest stretch of nice weather

The Maine Forecast — Tracking Maine’s weather patterns

There are lots of superlatives to use for the weather the past several days. Since late last week conditions have been nearly ideal. We all know this stretch had to come to an end, but need rain so it’s a good thing.

There are lots of clouds around the region today and there have been plenty of showers up along the New Hampshire border in the western part of the state. These showers have been on and off with a few heavy downpours.

As the afternoon progresses the rain area will move south and eventually Portland will see some rain and even thunder. While the weather was certainly comfortable this weekend and the first two days of the work week, it’s now turned a bit more humid.


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

Dew points, a measure of the amount of moisture in the air have been running very low the past 5 days. Now, they have crept back near 60F. This means you can feel the moisture in the air. Remember, there is always moisture in the air even at 10 below zero, there’s just not enough for us to feel it.

Since there is so much moisture in the air, eventually, when we do get showers, they could cause some street flooding and localized driving issues for a time.

Overnight this rain area is going to creep south and east. The image below shows where the showers are forecast, according to one model, around 6 AM. This shows it pouring across much of Maine with a tremendous amount of rain in places and the rumble of thunder.

As the day progresses tomorrow the rain will shift south and east. The morning commute will be very wet, but the evening should be much better. Let’s look at where the rain will be early in the afternoon. According to this model there will be some rain over eastern areas, but the rest of the state should be drying out.

Late in the afternoon tomorrow the risk of showers will have gone down enough to remove them from the forecast. Are you fortunate to be heading to Boston for the Billy Joel concert tomorrow evening at Fenway Park? The good news is it should be good to go. It will be more humid than southern Maine, but not oppressive.

Another concert Friday and Saturday at Fenway, plus scores of other events around the region should take place without the worry of showers. It won’t be cloud free Friday and Saturday. The cool air over us will act as a catalyst for some puffy cumulus clouds. I suppose there could be a quick shower over inland areas, but in general you’ll notice the dry and comfortable conditions.

High tides are going to be about noon both days this weekend and as the water temperatures continue to increase, it might be time for a swim in the ocean. It’s amazing how fast the lakes are warming now with many running into the mid-60s. Hard to believe they were all frozen 12 weeks ago.

Next week could turn very warm to hot with more humidity. This is going to be the first really significant stretch of summertime weather when we have several days in a row close to 90F inland and in the 80s at the coast with higher humidity. Welcome to July.
