The National Weather Service has us under a Freeze Warning Monday night into Tuesday morning. With clearing skies tonight expect widespread frost. High pressure will continue to dominate leading to clear skies and below average temperatures for the remainder of the week.
Forecaster:  Johnston, Danaher, Brown, Hirsch and Market

Technical Discussion (The nerdy stuff we are discussing in class!)
High pressure will move in and dominate our weather for the remaining portion of the forecast period. This will cause cold dry air to move in which has lead to a freeze warning for tonight.   The high pressure hanging near us is sitting at 1030+ mb, keeping skies clear and the atmosphere stable. The precipitable water values were minimal, with values less than .25 inches. Coupled with high pressure, there is low moisture in the atmosphere as the 700-1000 mb mean RH has 60% on Tuesday, so we don't expect much in the way of cloud coverage.  The GFS model was the main choice we used because of its accuracy along with the European models. With high pressure still influincing the area on Wednesday and Thursday, expect modifying temperatures. High temperatures on both days will still be below average with a cold air advection regime remaining prevalent. Warm air advection in the way of returning southerly flow on Friday should lead to increasing moisture and later shifts should watch for the potential for clouds and precipitaion.
