Tuesday was a little frustrating. The cloud cover lingered for a couple of hours longer than expected, but on balance, the afternoon turned out quite nice.
High pressure is now firmly in control and will remain so over the next couple of days. This is going to be one of the more perfect July Fourth's in terms of weather.
The day could certainly be cooler, but then it wouldn't be a great beach day. It could be hotter, but then it would be too hot to really enjoy the nice weather. I think this year will hit the sweet spot for sunshine, humidity and warmth.
Eventually the high pressure area is going to lose control and a cold front will approach. On Friday the chance of showers begins to increase, and it will peak Saturday into Saturday evening. This will end the longest dry streak since March.
Along with the showers the humidity will also go up. It will be very uncomfortable Saturday. If you're making plans for the weekend, Sunday is going to be the better of the two days. As long as this frontal system keeps moving, showers should end by Sunday and the humidity will also drop.
I expect a mainly sunny Sunday, although there could be some clouds during the first part of the day. The dry and warm weather will continue into early next week, but eventually, once again, the humidity will start to rise as we get into another week.
