A weak disturbance moving through the Northwest is bringing isolated showers to the area today. With snow levels at 2,000′ this is mostly snow showers. Webcams this morning have shown light snow covering some of the higher elevation roads from overnight and Tripcheck is reporting 2″ of new snow at Crater Lake and Diamond Lake.
The radar has been overshooting a lot of this shower activity so the showers can not be seen on the sat/rad but they are out there. Butte Falls also had a light dusting this morning. Another disturbance will bring more shower activity later today so spotty rain/snow is in the forecast all day long for all areas. Most locations will stay dry though with a mix of sun and clouds.
Temperatures will be gradually cooling throughout the week. Wednesday through Friday a very cold air mass, similar to the arctic blast in December, will settle into the Northwest. This is going to bring morning lows into the single digits Friday in the Basin (subzero temps aren’t out of the question) and teens for West Side Valleys. This has the potential to bring a hard freeze again to the area so pipes may need to be protected prior to the week’s end. Even the Coast will be facing morning temperatures in the 20′s.
Into the weekend two potent waves of wet weather will move right into Southern Oregon & Northern California. Right now, this weekend is looking beautiful in every way. The computer models are bringing in widespread moderate to heavy rain. The only thing I have noticed is that snow levels are rising significantly with the arrival of the moisture both Saturday and Sunday (when prior to Saturday they are extremely low). This may limit the amount of snow the high terrain picks up. Either way, we are still four/five days out and this could change. For now, lets keep our fingers crossed for some active weather!
