After the rain and snow that fell in the region Friday and Saturday, high pressure is building in. This will promote a very different weather pattern for the entire week. A very strong ridge is moving in from offshore which will keep low level clouds from forming and will promote very warm temperatures. Temperatures Sunday afternoon were already 10-20 degrees warmer than the afternoon highs on Saturday.
Even so, warming will continue further through the week. Highs on Monday will be in the 80s for the Rogue Valley and Northern California. The coast and the Basin will see temperatures in the 70s, and some mountain locations will reach the mid to upper 60s. Warming will only continue further from there. Wednesday will be the warmest of the week as the middle axis of the high pressure ridge moves overhead. It’s looking like mid 90s for the Rogue Valley and Northern California, 80s for the coast and Basin, and mid to upper 70s for the Cascades. Some record temperatures will be in jeopardy come Wednesday afternoon. The closer we get to the middle of the week, the higher the temperatures seem to be climbing. Happy Camp, CA is looking to be the warmest area Wednesday with a high in the upper 90s!
In the long term, it seems as if the temperatures will begin coming down on Thursday. Clouds will start moving in to the region on Friday as the ridge begins breaking down. Moisture will show up along the coast by Saturday. A low pressure system will swing a cold front through the area on Saturday. Went with a slight chance of isolated showers for the coast and the Cascades Saturday and Sunday. The closer we get to the weekend, we’ll have a better idea of how much precipitation we can expect with this system.
