From MTR AFD:
.LONG TERM... (Monday through Saturday) Issued at 248 AM PST Sun Feb 2 2025 Light showers continue Sunday into Monday with the next round of higher intensity rain returning late Monday morning/Monday afternoon. Taking a look at the synoptic pattern, an upper level trough off of the PNW and an upper level ridge over southern CA have in part kept our moisture plume tighter and pushed farther north this weekend. By Monday, the upper level trough will deepen over the PNW, pushing farther into northern CA, and ridging over southern CA will start to shift eastward. This will allow for the moisture plume to widen and shift southwards again late Monday morning/Monday afternoon with precipitable water values generally increasing to greater than 1" across the region. At the same time, the stationary front over the North Bay will give way to a more progressive cold front that will move through the Bay Area Monday into Tuesday. Rain will start to pick up in intensity by mid to late Monday morning with the initial heaviest rain located in the North Bay. High resolution models are starting to show precipitation lingering over the Bay Area (south of the North Bay) and Santa Cruz Mountains overnight Monday through Tuesday morning. Totals have trended upwards Monday into Tuesday with an additional 3"-4" possible across the North Bay, 2"-3" across the rest of the Bay Area, and 1"-3" across the Central Coast. Locally higher totals (4"+) are possible in areas where upsloping is favored (North Bay and coastal mountains). A slight chance (<10%) of thunderstorms continues to be monitored for Tuesday morning but the probability has been trending downwards recently. Wet weather will then continue Wednesday through the end of the week as troughing persists over the West Coast. Late week rain totals will be lower, however, with most areas seeing less than 1" of additional rain. The exception, again, will be where upsloping is favored within the coastal mountains where totals will be between 1"- 2". This second system will be colder with morning lows expected to drop into the mid 30s to low 40s across the region. The combination of damp weather and cooler temperatures may create conditions that are particularly hazardous for people without access to adequate heat or shelter. It is worth noting that the WPC maintains a slight to marginal risk of excessive rainfall for the Bay Area and portions of the Central Coast through Tuesday and again on Thursday. Flooding concerns will remain elevated through the week as our initial rainfall from Friday to Saturday have caused soils to saturate. This will lead to increased surface runoff and is likely to lead to additional flood related products as we move through our next two rounds of wet weather. In addition, gusty winds are likely to persist for coastal areas and elevated terrain Monday through Wednesday with the strongest gusts likely to develop ahead of/around the time of cold frontal passage Monday into Tuesday. This may result in a few trees being knocked over and increased potential for power outages to occur. Make sure to have multiple ways to receive warnings and stay up to date on the forecast as we move through the upcoming week.
