| Area Forecast Discussion National Weather Service Seattle WA 311am PDT Wednesday April 24 2024 Synopsis Weak front moving inland today. This will mark the beginning of a cool and wet last week of April with an upper level trough over the area and a couple of systems moving through over the weekend and Monday. Snow levels will lower over the weekend to near 2500 feet Monday for possible snow on all the mountain passes the first part of next week. Short Term - Today through Friday A pattern change brings cooler and wetter weather back to western WA starting today. This is due to an upper low moving through B.C. while dragging a weak front over the region. KLGX is picking up on light rain along the coast this morning. Rain will spread into the interior this afternoon with light amounts expected - trace to 0.05" along I-5. With onshore flow and cloudier conditions temperatures will track closer to average and in the 50s. Wet weather continues on Thursday with an upper level trough crossing the area. Precipitation totals, overall, are greater compared to Wednesday with measurable rain expected across all lowlands. Showers linger into Friday with a deep trough across the West. Widespread measurable rain is expected again across the area. Three-day rainfall totals are around 0.50-1" in the interior with 1-2" along the coast. Snow levels are around 4500' for mainly rain at the Cascade highway passes. 33 Long Term - Saturday Through Tuesday Upper level troughing over the Pac NW continues into this weekend for more rain and (high elevation) mountain snow. There's little break in the action with a pair of frontal systems pushing inland, thus maintaining moist S/SW flow over the area. A deep upper low wobbles overhead as we move into next week, keeping the air mass cool and showery. Lows will track cooler than average and in the mid to upper 30s to lower 40s. The cool spots will be over the south sound. Highs will also be a few degrees below average and in the mid 50s. Snow levels will lower to around 2500' on Monday and the mountain highway passes may see a few inches of snow. Overall, a cool and wet end to the month. 33 Marine A weak frontal system is approaching the area from the northwest. Winds through Strait of Juan de Fuca are still at SCA (Small Craft Advisory) levels but should weaken later in the morning as onshore flow diminishes. A more substantial system will move through the area waters on Thursday. Some uncertainty remains in the extent of its wind field but decided to issue a SCA (Small Craft Advisory) for the southern most zones of the outer and inner coastal waters where gusts will meet thresholds at the very minimum. A weak surface ridge will momentarily ease wind speeds for Saturday before an active pattern re-emerges Sunday. Seas look to remain 4 to 6 feet at about 10 seconds through the rest of the week and into Saturday. McMillian Hydrology No river flooding expected in the next 7 days.
