It’s starting to look like the persistent ridge of high pressure that has been giving us the unseasonably dry and warm weather is showing signs of getting weaker. The first wave chipping away at the ridge is moving through today and tonight giving us the clouds and cooler temperatures. However, with the combination of this first wave being weak along with contending with a very dry atmosphere any rain we do see will be very light. However, this will help set the stage for the next storm scheduled to arrive Wednesday into Thursday which is also a lot stronger and will be tapping into sub-tropical moisture. At this point it looks like the valley could pick up between a half of an inch to an inch of rain with more expected in the mountains. This will not get us out of our drought but at least it’s a start.
Another weak wave will move through on Friday giving us a chance for a few isolated showers but the bulk of any rain looks to fall Wednesday night into Thursday morning. Snow levels are expected to be around 5000 feet but could lower to 3500 feet by Friday.
It looks like the ridge of high pressure will try to rebuild next week but it doesn’t look to be as strong as it has been which means a better chance for at least some of the stronger storms to penetrate it. So at this point we’re not seeing much rain heading our way next week but at least the ridge won’t be as strong.
