A Short Heat Wave Coming?

As we've been talking about for the last four days, some very hot weather is on its way to the Stateline. Friday looks to be the hottest day at this point with a high of 95 degrees. A ridge of high pressure will build over the central US creating subsidence; a condition where air sinks from aloft to the surface, thereby reducing cloud cover and causing the atmosphere to warm by compression. A southerly flow at the surface will also create uncomfortably high humidity levels, and the combination of heat and humidity could cause heat indices to climb to advisory levels on Friday.

The 6 to 10 day outlook produced by the Climate Prediction Center (CPC, above-left) suggests this heat wave will be short-lived. After only slight cooling with more cloud cover Saturday and Sunday, a cold front will come through sometime on the 4th of July. This will signal a cooling trend that will bring our 6 to 10 day average to near-normal levels.
