WASHINGTON — On Memorial Day, the showers from Saturday and Sunday have headed out, and a drying trend starts with westerly winds kicking in and sloping down the mountains. Monday ends up being the driest day of the extended holiday weekend, complete with a break in the sticky humidity levels in the D.C. area.

But by the time most start heading back to work Tuesday, the humidity will return with only a slight chance for a few showers and thunderstorms as a weak disturbance moves through. It will send a weak cold front through the area, which will get another break in the humidity temporarily for Tuesday night and early Wednesday.

The humidity will return briefly again Wednesday with yet another cold front moving through with a slight chance of a thunderstorm.

Then, high pressure from central Canada will dominate Thursday and Friday with much lower humidity levels.

With high temperatures likely to be so close to each other this week, a better way to gauge changes in the weather day-to-day would be by examining the dew points. The dew point is a type of temperature, and all you need to remember is that the higher it is, the more moisture there is in the air, and the higher the amount of moisture there is, it can feel downright tropical.(Data: The Weather Company | Graphics: Storm Team 4)
