Record Heat to close Out April

What a Monday we had. After a few early morning showers, skies cleared and we had full sunshine. That boosted the temperature at Dulles to a record tying 86. No doubt that the winds helped warm things up. You see, as the winds, which were from the west-northwest, come down from the mountains into the lower elevations, they warm up. The amount they warm up depends on how much elevation change there is, which compresses the air, along with the dryness in the air.

A front will bring the threat for some showers tonight into Wednesday morning. As we head toward the rest of the week, we'll see some cooler weather with highs in the 60s and 70s. Next weekend should be very nice with sunshine and highs in the 70 - 75 range.
