Water Vapor Flux Analyses and Forecasts

These plots show wind at various levels colored by speed, freezing layer (black dots/dashed line), integrated water vapor (cyan line), upslope wind speed (purple or brown bars), upslope integrated water vapor flux (blue line), and hourly precipitation (green or red bars) with time moving from right to left.

Radar and Disdrometer Precipitation Analysis

This plot shows a comparison between S-band radar at multiple sites and the 0.5° elevation scan from the Sacramento, Ca WSR-88D scanning radar, as well as disdrometer and tipping bucket rain gauge data. Data shown for the previous 24 hours with time moving from left to right. Place mouse over site name or point on map to show most recent data plot or click to open in a new tab.

Snow Level Radars

The following images show data from various snow level radars. Each plot shows color shading of vertical radial velocity and circles depicting the snow level indicated by a radar bright band when bright band precipitation is present. Each plot shows the previous 48 hours of data with time moving from left to right. Place mouse over site name or point on map to show most recent data plot or click to open in a new tab.
