With high pressure still expected to be the driving force behind our weather today and tomorrow, expect plenty of sunshine and low humidity… While it’ll be warm, the temperatures today will be near or slightly BELOW the seasonal averages today and it should be very close to normal for tomorrow, the first day of July.

The holiday weekend will bring with it a couple of forecasting challenges… First of all, the leading edge of some hot and more humid air will probably be reaching the Great Lakes and eastern parts of the Ohio Valley tomorrow night before it moves into the mid-Atlantic states on Saturday… A slow-moving weather front dropping out of the north and west Saturday night and Sunday will be a catalyst for causing some widely-separated thunderstorms… In a “best case  scenario”, we would only need to worry about these impacting Baltimore’s weather (as well as at the Shore) on Sunday, <<<IF>>> the boundary were to keep pressing to the south on Sunday afternoon and evening… That would allow for some drier (but not necessarily “cooler”) air to filter in for the Fourth of July.
On the “flip side”, a slower-moving front would lead to a few additional showers and a thunderstorm on Monday, the Fourth of July… Right now, we should be cautiously optimistic about the holiday itself, but we want to stress that Saturday and Sunday are probably the “most active” days when it comes to showers and thunderstorms.
