High & Low Pressure Circulation

“Why do low pressure and high pressure rotate in opposite directions?” Dave Wilson Central Point Because the sun heats the earth’s surface unevenly it causes air to expand and contract at different places across the globe. As a result, air pressure is different at all points on the earth. It’s these pressure differences that cause … Continue reading »

Isolated Showers This Evening

Most of the activity was in the morning with a gradual diminish through the afternoon. Showers … Continue reading »

Getting Off to a Great Start This Week!

Winds have shifted to the Northwest now so some clouds have come in from our North. Partly cloudy skies this evening will keep us warmer than the past several nights.
