The higher the dew point, the more moisture there is in the air. It will be a dramatic rise during the two-day period.  (Data: RPM Model, The Weather Company/ Graphics: Storm Team 4)

This map is the computer model future radar for midday Wednesday. The cold front will be marching across the country, but most of the thunderstorms along it will be concentrated north of our latitude. By the time the front gets here Wednesday night/Thursday morning, a lot of the storms may be falling apart and it may not rain here at all.  (Data: RPM Model, The Weather Company/ Graphics: Storm Team 4)

A quick look at the feel of the week ahead. It’s interesting in that the temperatures and the humidity levels will basically be rising and falling hand-in-hand ahead of and behind the midweek cold front.  (WTOP/Storm Team 4)

WASHINGTON — The workweek’s weather will be mostly dry and uneventful. The week is already off to a very pleasant start, thanks to the cold front that passed through early Sunday morning, breaking last week’s heat wave.

The weather looks perfect for the Washington Redskins’ home and season opener Monday evening. A sprawling area of high pressure dominating the better part of the eastern half of the country will provide dry, comfortable weather before sliding out to sea, allowing some warmer and more humid air to return.

But it won’t be another heat wave.

This pattern will be fairly progressive, and another strong, fall-like cold front will pass through in the Wednesday/Thursday time frame. It’s unclear at this point if that front will have any precipitation with its passage. But it will definitely be followed by some actual cooler-than-average temperatures and much less humidity for Thursday and Friday.
