Summary- Strong upper high pressure will continue over the central north Pacific, with a stationary trough in the subtropical central Pacific. This supports a transition to colder conditions during April 27-30th and May 1-2.
Summary- We have been in an abnormally cool pattern for most of California. We appear to transition into a warmer and drier pattern for April 28-30 and May 1-3. Support continues in the mid-latitude Pacific sea surface temperature field for troughing to return near the N and central California coast, and about normal precipitation.
Summary- Most rains focus on the SierraNV (rain and snow), and N California as far S as the Bay Area. Troughs and fronts alternate with periods of warm dry upper high pressure from April 13th through the 26th. Our CFSDailyAI system suggests some showers in the central and N SierraNV from April 28-30th, then into S California on May 1-2. Another rain with some TSTMS is suggested in the SierraNV...
Summary- Fronts come through with significant rains on April 5-7th, rains on 10th, showers in N California on 12th, and some more showers in the N SierraNV and N California on the 15th and 18th. Support continues in the mid-latitude Pacific sea surface temperature field, for high pressure near 145-160W 37-43N, a trough near 135-128W with a shift of active westerlies further north to focus on NW...
Summary- Mostly dry and somewhat inactive period through April 3, with a minor cold front on the 27th. Unusually warm and dry.
