DISCUSSION

The morning there will be showers and thunderstorms moving into Northern California around 10 AM- 12 PM, and this will continue moving north through the afternoon. Forecast afternoon CAPEs are reaching 250- 400 J/kg, and this is concentrated in Siskiyou County and on west side. Most of the thunderstorm activity will be in Siskiyou County and west of the Cascades, with a 30-40% probability at its peak this afternoon. CAMs are supporting this northward movement, and once again this has some of the thunderstorms arriving in Jackson and Josephine counties near the end of the school day (1-3 PM).

Most of the Southern Oregon activity will occur between 1-6 PM, although forecast CAMs show some scattered shower activity between 6- 8 PM in Jackson County to eastern Douglas County. A general thunderstorm risk exists today and tomorrow across the area, and gusty winds and downpours are possible in the strongest storms. Snow levels will fall to 5,500'-6,000' tonight, and the heaviest snow will fall in Northern California. Between 11 PM tonight through 11 PM Saturday, near 8"-12" is forecast to fall in the Marbles and near 2-3 feet at Mt. Shasta. Through the weekend the Cascades are forecast to see mostly 2"-5", and 6"-9" near Crater Lake.

Long Term: Heading into next week, nothing really stood out on the extreme forecast index(EFI). There are some hints at another trough sliding down the north west, which would lead to cooler more unstable air and more showers for the forecast region. The probability of precipitation increases around Tuesday and Wednesday during this time with a 50 to 60 percent chance of precipitation. 10% of the ENS members show the Cascades seeing another 3-6 inches of snow with this northwest flow and cold front around Wednesday. So there is still a chance to get some more snow in the mountains here in early April.

AVIATION...10/12Z TAFs

LIFR ceilings are present in west side valleys. North Bend observations are out, however satellite and nearby observations bring more confidence that there is LIFR conditions there as well. These conditions are expected to improve later this morning, however showers and thunderstorms move in from the south then. Between 2-6 PM is when there will be the most activity in Southern Oregon. Gusty and erratic winds are possible. Thunderstorm activity is forecast to ease around 8 PM, although scattered showers will continue along and east of the Cascades tonight. -Hermansen
