Another gorgeous spring-like day with abundant sunshine and temperatures this afternoon just above normal for March, but it all ends today as a strong cold front will bring heavy rain, snow and gusty winds to the area tomorrow. Tonight we’ll see rain begin at the coast with moderate to heavy rain through Tuesday evening, moving inland with heaviest rain tomorrow afternoon through Wednesday morning and snow levels starting off around 4,500 feet then dropping to 3,000 feet with the passing of the front tomorrow afternoon and down to 2,500 feet by Wednesday morning. With dropping snow levels and temperatures snow will not immediately accumulate on roads tomorrow afternoon but tomorrow evening through Wednesday snow will begin to accumulate and may cause hazardous travel at times for many roads including I-5, Lake of the Woods and Diamond Lake Summit. A Winter Storm Watch is in effect for Siskiyou county above 4,000 feet for this system with the potential of 6″-12″ of new snow and gusts to 50 mph. What else to expect:
Coast: Tonight through Tuesday night moderate to heavy rain and gusty winds up to 40 mph, with lighter rain continuing Wednesday and a chance for thunderstorms and potentially small hail.
West Side: Moderate to heavy rain Tuesday and breezy. Potential for snow in the foothills overnight Tuesday and a better chance for some lower elevation snow Wednesday night into Thursday morning. This is the tail end of this system though so it will be light for any snow showers that form.
Cascades: Heavy snow Tuesday late afternoon through Wednesday morning and gusts up to 50 mph. Could see new snow 4 to 8 inches with this system making pass travel hazardous at times.
East Side: Light rain tomorrow afternoon turning to snow Tuesday evening with heaviest snow Tuesday night into Wednesday morning with 1 to 4 inches of accumulation possible. Windy Tuesday with gusts up to 50 mph and gusts to 35 on Wednesday.
Northern California: The heaviest snow will fall here with up to a foot of new snow in the Siskiyou’s and with gusts up to 50 mph visibility may be low with blizzard like conditions at times. The Mt. Shasta City area and I-5 look to get hit hard with this system so be sure to check road conditions if heading out and avoid travel if possible.
I’ll be updating my Facebook with weather and road reports, especially with this strong winter storm. Thanks for logging on and enjoy this beautiful Monday!
