Here is my weekly weather quiz question for the last time “What is “Snotel?” Here is the correct answer. SnotelSNOw TELemetry – is an automated network of snowpack data collection sites. The Natural Resources Conservation Service (NRCS), formerly the Soil Conservation Service (SCS), has operated the Federal-State-Private Cooperative Snow Survey Program in the western United States since 1935. A standard SNOTEL site consists of a snow pillow, a storage type precipitation gauge, air temperature sensor and a small shelter for housing electronics.

An Upper Level Low Pressure Area will be ushering in marine moisture which means we’ll get weekend rain chances. The graphics for days 1-3 show a frontal system moving into Northern California and headed our way today as it continues moving to the northeast. The graphics for days 3-7 Tuesday through Saturday show a frontal system pushing into California and Oregon between Wednesday and Thursday.
