Getting out from under the wedge
Posted Mar31, 2008 at 11:31 PM
It might feel as if we've all been under a cold, wet blanket the last couple of days. That is called a "wedge" ... a layer of cool, moist air at the surface that has been shoved by high pressure to the north against the eastern side of the Appalachians. It has slowly modified the last couple of days, rising from near freezing Sunday to the 40s on Monday. During the day Tuesday, the wedge will finally erode, and we'll shoot into the 60s ... just in time for a cold front to bring showers and storms and a slight cooldown. Most of the rest of the week looks fairly normal for early April, though, with highs in the 60s and lows in the 40s.
