Area Forecast Discussion National Weather Service Medford OR 933pm PST Monday Dec 2 2024 It managed to clear out across most of the forecast area this afternoon giving us the opportunity to witness our closest star! The exception was the Illinois Valley near Cave Junction which held the clouds again all day. After several days without any precipitation and a dry air mass overhead, soil moisture values are decreasing and so is the low-level moisture in the valleys. So, the low clouds/fog have a bit less staying power than they did the past few days. The added hours of sunshine sent the temperature up to 46F here at the airport, a veritable heat wave given the last few days of temperatures stuck in the upper 20s and low 30s. Looking at satellite this evening, the sky is clear across a large portion of the forecast area as upper ridging rebuilds. We can also see, however, the low clouds and fog redeveloping in the west side valleys. Expect the fog/low clouds to continue to form in the valleys overnight into Tuesday morning resulting in reduced visibility and possible freezing fog for the morning rush. So, please be careful during the morning commute. The low visibility in areas of dense freezing fog could make driving conditions hazardous. Most valley areas will radiate and turn cold again overnight with lows in the upper 20s and low 30s west of the Cascades. Coastal Coos, Douglas and northern Curry counties are in another Frost Advisory. East side areas will have lows largely in the teens and 20s, but some single digits are possible in the Klamath Marsh area north of Chiloquin. -Spilde Marine Updated 800pm PST Monday, December 02, 2024...Light to moderate north winds and relatively calm swell dominated seas will persist into Wednesday. Longer period west swell height and period diminishes slightly today into Tuesday, while winds increase slightly this afternoon. But, both winds and swell remain below advisory levels. A warm front is expected to approach the waters Wednesday night into Thursday, with winds shifting to southerly. The front will likely move through Thursday night into early Friday with the highest winds and seas north of Cape Blanco...possibly approaching advisory levels. Winds and seas may similarly nudge higher again with the trailing cold front Friday night into early Saturday. -BPN/Spilde /Issued 220pm PST Monday Dec 2 2024/ Dry weather will continue through Wednesday. Satellite image shows the low clouds and fog burning off in areas that remain socked in the last few days. The one area that may not break out will be in the Grants Pass area and Illinois Valley, otherwise the evening will start out clear. The pattern overall is not going to change, therefore we'll see fog and low clouds return later this evening and lasting into most, if not all of Tuesday morning. It's not out of the question fog and low clouds could carry over into the afternoon, especially in the Illinois Valley and Grants Pass area. However, confidence on this is not high. We'll likely see a repeat scenario of the fog and low clouds in similar areas Tuesday night through at least Wednesday morning. The duration of low clouds and fog in the valleys will also result in cooler afternoon temperatures than what guidance is indicating. -Petrucelli Long Term12Z Thursday into Tuesday the 10th The persistent high pressure over the region will come to an end around the Thursday time period. Ensembles showing an upper level low moving into the state of Washington with a warm front pushing into the region between Thursday and Friday. Models are generally hinting at some precipitation along the coast and in the higher terrain. The probability of precipitation is about 30 percent in those locations. This upper level wave will help get us out of the pattern of persistent freezing fog in the morning. Another ridge will build in briefly Friday afternoon with some warmer tropical air. Temperatures could push into the upper 50's in some of our west side valleys if the fog doesn't linger around too long. That will change by Saturday as models are in pretty good agreement a cold front will push through the forecast area. It's not guaranteed we'll see wetting rain as about 60% of the models bring precipitation to southern Oregon, while the other 40% keep southern Oregon dry with most of the rain and snow falling to our north. Overall, the weather moving into the region on Saturday will produce minimal impacts, even in the wettest solutions out there right now. Beyond the front on Saturday, there is not eye catching in the extended forecast. There are a few ensemble members that are predicting a weak atmospheric river hitting areas to our north with little to no precipitation moving into southern oregon Monday and Tuesday. -Smith anchored in many of the valleys based on the latest satellite imagery and surface observations. We were looking to see if the edges of the fog might start burning off this late morning, but the chances of that are low given the low sun angle. If we do clear out, it will be a brief period in the afternoon. The last few days we have seen some improvement in visibilities and guidance suggests that is possible closer to 0Z here in Medford(MFR). The freezing fog will build back into the valleys tonight with more LIFR conditions. An upper level shortwave could weaken the strength of the inversion, although the freezing fog should still fill in the valleys. -Smith Marine Updated 200pm PST Monday, December 02, 2024...Light to moderate north winds and relatively calm swell dominated seas will persist into Wednesday. Longer period west swell height and period diminishes slightly today into Tuesday, while winds increase slightly this afternoon. But, both winds and swell remain below advisory levels. A warm front is expected to approach the waters Wednesday night into Thursday, with winds shifting to southerly. The front will likely move through Thursday night into early Friday with the highest winds and seas north of Cape Blanco...possibly approaching advisory levels. Winds and seas may similarly nudge higher again with the trailing cold front Friday night into early Saturday. -DW/BPN NOAA Medford OR Office: Watches - Warnings - Advisories OR...Frost Advisory until 9am PST Tuesday for ORZ021.
