The laziest front ever is still slowly approaching the city today, and its languid approach has allowed lots of moisture to gather in the area. The dew point is hovering around 70 degrees and the precipitable water, which is the amount of water that could be condensed from the air above our heads, is approaching two inches. With all that water it won't take much of a disturbance to get some rain falling. Look for an increasing chance of showers and thunderstorms from this afternoon until about midnight. Some of that rainfall is likely to be intense primarily because we forgot to bring an umbrella to the office. The heavy cloud cover will keep this afternoon's high to the lower 80s.

A dry air mass will arrive overnight. Both Saturday and Sunday will be peachy with highs in the mid 80s under mostly sunny skies.

Humidity returns to the picture early next week as the high pressure system moves offshore and the wind swings around to come out of the south. In contrast to the pleasant weekend, Monday and Tuesday are shaping up to be pretty warm and sticky. The next chance of showers will be Tuesday afternoon.
