Summary:
- A cooler than average March in California and the southwest, while the PNW and central to northern Rockies experienced a warmer than average month.
- A wet March was had over northern California, most of Oregon and Washington, and the intermountain west.
- Drought conditions heading into spring either stayed roughly the same (southern California and the southwest) or improved (Oregon, Washington, and the northern Rockies). April 1 snow water equivalents made significant jumps in Oregon, northern California, and Nevada, while rising closer to average for most regions except the northern Cascades, Four Corners, and Front Range watersheds where very little moisture is carrying over into spring and summer.
- A typical spring seesaw over the next 10 days with very nice days interspersed with fronts and clouds carrying precipitation for many. Wetter conditions are likely from northern California into the PNW, drier likely in more southern regions of the west. No extremely cold air in the short term but clearing skies behind the fronts will bring inversions and scattered frost to inland valleys.
- The overall April forecast is holding equal chances of above to below temperatures and precipitation for most of the west. If I am reading things right there will likely be some colder and wetter conditions later in the month.
- The 90-day forecast is pointing to a warmer and drier California into the southwest and Rockies, while the PNW does not have a clear trajectory at this time. Trying to break these signals into individual months, my read on it is for cool to average in April, average to slightly warmer than average in May, then warm and dry into June.
