DISCUSSION
Moist onshore flow from the southwest is keeping some precipitation going in the orographically favored areas of Curry County this morning. And, some showers are moving through the Cascades north of Highway 140 and toward NW Lake County.
Overall, though, compared to this past weekend, our forecast area is in a relative break between systems. This is good because all the rain over the weekend (5-10 inches in many areas along the coast) has led to significant rises on rivers, streams, creeks just about everywhere west of the Cascades. And, there is a flood warning currently in effect for the Coquille River at Coquille.
Other rivers have peaked and should come down a bit today through tonight.
If you've been outside, you can feel the difference in air mass compared to last week with subtropical air and dewpoints west of the Cascades in the 50s getting into the mix. This surge of moist air sent snow levels up above 9000 feet. We'll keep this air mass in place the rest of the today and into tomorrow, but satellite imagery is showing the next atmospheric river offshore. This system will approach the coast tonight with another round of significant rainfall at the coast Tuesday/Tuesday night. Given all the recent rainfall, there will be a renewed risk of flooding for areas in Curry, Coos, western Josephine and western Douglas counties. We are maintaining the Area Flood Watch for this reason, which is up through Wednesday afternoon. Some ponding of water on roadways is likely with this next rain event, along with flooding in areas of poor drainage. Rivers, streams and creeks could see a second bump upward. The good news is this front/AR will be moving inland and the heavy rainfall shouldn't last as long as it did this past weekend. Gusty winds will develop over the east side in advance of the front on Wednesday. We'll be looking into the potential for a wind advisory for then. The last element will be the drop in snow levels expected as the front passes Wednesday night into Thursday. Right now, it looks like snow levels will get down to around 5000 feet Wednesday afternoon, eventually reaching as low as 3500-4000 feet Thursday morning. This will bring some snow impacts for the Cascades and Siskiyous above 4000 feet. Most likely amounts right now Thursday-Thursday night are in the 6-12 inch range north of Highway 66, and in the Siskiyous west of I-5; 1-3 inches up at Siskiyou Summit and along Highway 97 from Chiloquin northward .

04/18Z TAFs...Along the coast and just offshore, MVFR and occasional IFR ceilings are expected to persist through the TAF period. However, could not rule out brief periods of VFR conditions, south of Cape Blanco this afternoon and early this evening. A frontal boundary is close by and this will result in increasing south winds, including north Bend this afternoon. Until then low level wind shear will be a concern at North Bend until the stronger south winds develop.
Elsewhere, VFR ceilings are expected to be the predominate condition. However could not rule out partial mountain obscurations into this evening. Low level wind shear will be a concern at Roseburg this evening until the end of the TAF period, but were not expecting it to be a concern at Medford and Klamath Falls.

Updated 845 AM Monday December 4, 2023...An active period of weather will continue this week over the waters. Gusty south to southwest winds will be common, along with southerly wind waves and long period west swell.
Winds will increase through the morning hours today, and seas will remain steep once again through Tuesday morning. Gales are expected again north of Gold Beach today through Tuesday morning. In addition, seas are expected to become very high later today around 15 to 19 ft and will continue to build to a peak around 16 to 22 ft Tuesday into early Wednesday morning. During this same time period, wind speeds are forecast to come down relatively speaking. However, since seas are still expected to remain very high, this will result in the need for a Hazardous Seas Warning across all the waters Tuesday through Wednesday morning. Additional disturbances Wednesday and Thursday will not be as strong, with high and steep seas slowly diminishing into Friday.

DISCUSSION...We're in a relative break between atmospheric river systems today, with limited precipitation in the region. Good mid- level moisture and westerly flow is creating conditions that support enhanced (orographic) shower activity over the south OR Cascades and Curry County mountains, but elsewhere occasional light rain is all you can expect through at least Tuesday morning.
Low temperatures this morning will be a couple degrees warmer than yesterday's for most inland areas due to continued low-level southwesterly flow bringing warmer (relatively) air into the area.
Similarly, afternoon high temperatures will be similar to if not a couple degrees warmer than yesterday's. This warm flow will also continue to raise snow levels to above 9,000 feet by late this morning, so besides OVER the peak of Mt. Shasta all of our precipitation today will fall as rain.
Heavy rainfall in the last few days have led to rapid rises in small streams and creeks. As rain has ended, most of these streams will drop briefly today before the next system rolls in, with the exception of the Coquille River at Coquille, which has reached full capacity/bankfull as of writing this and is forecast to reach minor flood stage today, and our flood warning for this remains in effect.
Another atmospheric river will slowly move onshore Tuesday, moving inland late Tuesday through Wednesday. This will bring widespread moderate to heavy precipitation to the region, with rain starting along the Coos County coast and northwards Tuesday morning, then gradually spreading southward to include the Curry coast and coastal mountains Tuesday afternoon into Tuesday night. Areas further inland can expect to see precipitation late Tuesday into mid- Wednesday. Areas along the coast can expect to see another 2-5" of rain out of this, with about 1-2" forecast further inland in western Josephine and west/central Douglas counties. This heavy rainfall will lead to additional rises in streams and rivers in this area, and a flood watch remains in effect for Coos, Curry, western Douglas and western Josephine counties through Wednesday for potential flooding of rivers, creeks, streams, and other low-lying and flood-prone locations.
Winds will pick up again as the atmospheric river moves in, especially Wednesday morning and afternoon, as it brings a 45-55 kt 700 mb jet into the area. This will result in gusty southwest winds over ridges, especially over the Klamath/Curry County Mountains and typically windy areas east of the Cascades such as the Summer Lake/Winter Rim area and the Warner Mountains.
Snow levels will once again drop through the day Wednesday as the stream of more tropical moisture cuts off and a trough moves in aloft, bringing a cooler air mass. Snow will return to the mountains (Cascade, N. CA Siskiyou, and Warner ranges) by early Wednesday afternoon. The progressive pattern continues into the end of the work week, as another trough and associated frontal system moves through the area Thursday.

04/12Z TAFs
Terminals are precipitation free for the time being, but we are still seeing low ceilings across the terminals. This has resulted in areas of MVFR conditions (or close to at least) and this will be the case for most of this cycle.
Medford could see visibilities drop to IFR later this morning and once again Tuesday morning. Precipitation will return to the area again today, but should be less coverage today/tonight (compared to the last couple days) and hence the omission of any prevailing rain at the terminals outside of Klamath Falls (KLMT). Even then, confidence is on the lower side for KLMT to see rain showers actually impact the terminal.

BEACH HAZARDS...Active weather continues this week. A series of fronts will move through the region during this time along with multiple moderate to high swell trains. An extended period of sustained wave action is expected through Tuesday. Breaking waves of 15 to 20 ft will coincide with higher than normal ocean levels, leading to an increased risk of beach erosion. Additionally, there is a minor risk of sneaker waves as these swell trains build into the waters. Confidence is low, however, considering wind wave interference is likely to limit, but not completely negate the sneaker threat.
Late Tuesday afternoon into Wednesday morning, very large breaking waves of 20 to 30 ft are expected due to large long period west swell. In addition, another moderate risk for sneaker waves will also be present Tuesday evening. If venturing to area beaches during this time, use caution when visiting and remember to never turn your back on the ocean! -BPN
