Area Forecast Discussion National Weather Service Medford OR 1004 AM PST Thu Jan 20 2022

DISCUSSION. No updates are necessary this morning.

A weak frontal system will continue to push through the area today. While a few light showers did pass through Jackson County and into the Cascades earlier this morning, additional showers are most likely to remain along and near the coastal ranges, in the Oregon Cascades, and from the Umpqua Divide northward. However, a few mostly non-measurable rogue showers could make it as far south as the Siskiyous late this afternoon into early this evening. ~BTL

AVIATION. 20/18Z TAFs . A weak cold front will produce some lower to mid clouds over the area today. Expect continued areas or MVFR cigs and local IFR cigs along with scattered light showers over northwest portions of the area, mainly across Coos and Douglas counties and into the Southern Oregon Cascades. Local MVFR cigs are possible for other areas west of the Cascades. East of the Cascades, some mountain obscuration is expected but terminals should remain VFR through early evening. Once the front passes by this evening, clearing skies are likely to allow valley low clouds and fog to develop overnight. Areas of IFR/LIFR are expected to develop tonight into Friday morning in the valleys west of the Cascades in low clouds and fog. For valleys east of the Cascades, local IFR conditions are expected in patchy freezing fog tonight into Friday morning. -CC

MARINE. Updated 800 AM PST Thursday 20 January 2022 . Conditions will remain relatively calm under high pressure through this morning. A thermal trough will develop later this afternoon. This will result in gusty north winds and steep to very steep seas, especially south of Cape Blanco, tonight through Saturday afternoon. Lighter winds should return by late this weekend, but a longer period swell will also build on Sunday. Another round of gusty north winds and Small Craft Advisory conditions is possible by Monday when the thermal trough redevelops. -BPN/CC

PREV DISCUSSION. /Issued 329 AM PST Thu Jan 20 2022/

DISCUSSION . Yesterday's warm front has lifted well to the north of the area early this morning with a weak upper ridge axis near or just east of the Cascades. The ridge will shift to the east, allowing an upper trough and cold front to swing through the area today. Moisture with the front is limited, but some light showers are possible, especially across the northern tier counties, north of the Umpqua Divide and also north of Highway 140 in the Cascades. Rain amounts will be generally only a few hundredths, but a few places in the eastern Douglas County Foothills to the Cascades north of Crater Lake NP could exceed 0.10 of an inch. Farther south, patchy fog this morning will give way to partial sunshine and high temperatures about 5-10F above average. Mid 50s to near 60F will be common over the west side valleys with upper 40s to low 50s over the East Side.

A slight chance of showers lingers near the Cascades north of Crater Lake into this evening, but the air mass dries out rapidly overnight into Friday on rather brisk north through northeast mid-level (700mb) winds. Strong surface high pressure will build in Friday with strong upper ridging setting up offshore. This will induce a period of rather strong offshore east winds, primarily at upper slope and ridge level from the Cascades westward Friday through Saturday morning. Wind gusts up there will be 40 mph at times. Valley locations, however, will likely be sheltered from these strong winds due to a strengthening temperature inversion. Valley fog is most likely Friday morning. There could be some fog both mornings of the weekend too, but it probably won't be as widespread as the air mass dries out. Overall, expect large diurnal temperature swings with chilly mornings (cold East Side) and sunny, milder afternoons -- much like we had last weekend. Winds aloft will gradually ease Saturday into Sunday and this could result in stagnant conditions for the valleys. Day shift will take a closer look today to see if any air stagnation products are necessary.

A shortwave trough will swing through the area Sunday night and may provide better mixing into Monday, but the upper ridge (while not as strong as over the weekend) gets re-established Tuesday to Thursday next week. As a result, the dry pattern will continue with daytime temperatures several degrees above normal and nighttime lows near normal.

Ensemble systems continue to indicate a retrogression of the eastern Pacific upper ridge to near the Aleutians toward the end of January into early February, with a gradual lowering of heights over the western U.S. Largest positive height anomalies during this time period are indicated over the Gulf of AK northward, which favors a trough downstream over the NW or Intermountain West. It doesn't look overly wet, though, since in this type of pattern, we mostly end up with Pacific systems that ride over the top of the Pacific ridge and down into the NW. This makes atmospheric river systems, the ones that truly deliver significant precipitation to our area, less likely. Overall, though, this pattern favors a shift in temperatures (downward) and precipitation (upward) closer to the seasonal normals. -Spilde

AVIATION . 20/12Z TAFs . A cold front will continue to produce low to mid level cloudiness over much of the area today, with light showers possible, mainly north of a line from Cape Blanco through Crater Lake. IFR/MVFR ceilings and mountain obscurations will be common for most areas west of the Cascades, with fog and low clouds possible in area valleys where higher clouds clear. Once the front passes this evening, clearing skies are likely to allow valley fog to develop late in the TAF period. East of the Cascades, some mountain obscuration is expected but terminals should remain VFR throughout the TAF period. -BPN

MARINE . Updated 200 AM PST Thursday 20 January 2022 . Conditions will remain relatively calm under high pressure through Thursday morning. A thermal trough will develop Thursday afternoon, producing gusty north winds and steep to very steep seas, especially south of Cape Blanco. Lighter winds should return by late this weekend, but a longer period swell will also build on Sunday. Another round of gusty north winds and Small Craft Advisory conditions is possible by Monday when the thermal trough redevelops. -BPN
