More Spring Snow for PNW and Northern Rockies
An active pattern continues in the Pacific Northwest as more waves of energy move ashore this weekend. This will keep snow in the forecast for higher elevations, while slowly reducing drought conditions in the western United States. A few winter warnings remain in Montana and Wyoming as the snow eases through the day today.
Today we will see rain and snow in the Rocky Mountains with precipitation approaching the Pacific Coast.
Our next cycle of energy arrives Friday evening and carries us through Saturday with heavy rains along the Washington and Oregon coast.
The rain spreads inland overnight, with some snowfall at higher elevations. However, this system is warm in nature, so we don’t expect too much snow to accumulate outside of the highest peaks.
Saturday morning will see a drying trend in the I-5 corridor with rain and snow showers pushing inland for Washington, Oregon and Idaho.
A few trailing rain showers can be seen behind the front Saturday afternoon with high altitude snowfall concentrated in Idaho.
Things finish Saturday evening with only a few showers surviving late into the day.
Our forecast models point to the possibility of a foot more of new snow in the Rocky Mountains, mostly from Friday’s wetness. Additional light snow up to 2″ may be possible for the Cascades through Saturday afternoon and evening. Late season snowfall is critical to the success of our spring water.
Precipitation totals will approach an inch in some areas. This would be great news for the ongoing drought.
Speaking of drought, here’s an update. We are looking at most of the west with 90% MORE drought coverage. Washington State is the only region that does not experience such high levels of drought thanks to an active fall and winter regime. Yet even with our active rainy and snowy season, we are considering the long-term implications of the drought extending into summer.
We’ve seen our fair share of moisture in areas shaded blue over the past month, indicating soils are saturated. Accordingly, we will monitor the threat of flooding, especially for rivers, streams and streams.
