Forecaster: W Schalk
.Forecast Summary...High pressure will persist over the region into early next week. This will keep our area dry with above normal afternoon temperatures. Breezy northerly winds will also be observed at times through the holiday. The high may weaken just enough towards the end of the forecast period to allow a system to pass through quickly. Currently it looks dry but there will be an increase in clouds and wind with more normal temperatures.
