DISCUSSION
The forecast for today through Tuesday night is straightforward with this morning's trough passage as the main precipitation producer. Conditions look to be dry tonight through Monday, with another weaker, very weak shortwave trough that could produce a few mainly East Side flurries
The trough now extends from the Coast Range along the Umpqua Divide to the southern Oregon Cascades and could produce up to 3 inches of snow on the higher terrain of southwest Oregon, with snow levels now around 800 feet rising to 2000 feet by this afternoon. Amounts will be highest north of Lake of the Woods, especially from eastern Douglas County northward. Meantime, up to an inch of snow is expected for southern Douglas County into far northern Josephine County, including the I-5 passes between Canyonville and Grants Pass. Snow showers will taper off after 10 AM, with the last flurry expected around 5 PM.
Otherwise, the main weather story is well below normal temperatures through Tuesday night, including frigid sub-zero overnight readings for much of the East Side. This includes a current reading of minus 8 degrees in Lakeview. The Cold Weather Advisory in effect is well deserved. East side temperatures will be 15 to 30 degrees below normal readings for early February.
Meanwhile, valleys on the West Side have readings mostly 10 to 20 degrees below normal. This includes freezing low temperatures at the coast tonight through Tuesday night. This likely will be our coldest airmass of the winter, and it is notable for its length.
Also of interest, the Pit River near Canby has fallen below flood stage as of a couple of hours ago, which allowed the Flood Warning to be cancelled.
Uncertainty in the forecast quickly increases with an expected change in the weather at mid-week. The probability of stormy weather is highest for California, particularly south of our area.
But, the timing and track of individual disturbances shows a wide variation leading to differences in the extent to which our area will receive impactful precipitation. With a more southward track/focus, our snow levels will be lower, but precipitation amounts would also be lower. The blended model solution was utilized with precipitation as early as Wednesday, but the highest probability for wet, stormy conditions from Thursday into Friday. Snow levels are forecast to be around 2500 to 4000 feet.
Late in the week, at least a diminishment of activity, or possibly a full break in the pattern is expected for Saturday/day 7. But, further disturbances are likely for day 8 to 10.
AVIATION
08/12Z TAFs...A weak front is moving onshore this morning, and will push across the area through today, producing periods of MVFR/IFR conditions in showers and low ceilings along and west of the Cascades. Freezing levels will be low, with snow showers inland above 1000 feet. Even some wet snow could mix in at elevations down to around 500 feet at times (Roseburg), but little to no accumulations are expected for West Side valleys. Meanwhile, patchy freezing fog has developed in areas where the sky has cleared, including in the Klamath Basin, and there is the potential for fog development in other valleys before cloud dover associated with the front arrives. Confidence is higher for more persistent fog in the Klamath Basin as the incoming front could destabilize the atmosphere enough to limit fog development in West Side valleys.
Regardless, any lower conditions due to fog are expected to improve by late morning, but lower flight conditions due to the front will linger into the evening. Clearing skies tonight are likely to result in IFR/LIFR conditions in many area valleys tonight due to fog and low stratus clouds. -BPN/BR-y
MARINE
Updated 200 AM Saturday, February 8, 2025...A brief period of gusty winds and steep seas is expected this morning as a weak front passes. West winds in advance of the front will shift to northwest and gradually diminish once the front passes later this morning. Conditions improve very briefly tonight, then north winds and steep wind-driven seas increase through Sunday and persist into Tuesday, with the strongest winds and steepest seas south of Cape Blanco. After a period of lighter winds and lower seas Wednesday, a more significant storm is possible with strong south winds and very steep seas late Wednesday into Thursday. -BPN/Spilde
