| Area Forecast Discussion National Weather Service Medford OR 347am PDT Wednesday May 8 2024 Temperatures aren't dropping much this morning as dewpoints stay in the mid 30's across a lot of valleys west of the Cascades. The exception appears to be the Scott Valley with temperatures currently around 32 to 34 with dewpoints in the upper 20's. Other than the patchy freezing conditions across the forecast area this morning, concerns are minimal given the current temperatures. High temperatures will trend about 10 to 15 degrees higher today compared to Tuesday as high pressure continues to build over southern Oregon and northern California. A thermal trough will strengthen along the southern Oregon coastline this morning with some north east flow developing along the coastal range. Brookings and Somes Bar in south western Siskiyou County will be the warm spots later today with both pushing into mid 70's with Somes Bar potentially hitting the 80's. Overall, this is pretty typical for temperatures this time of year as Medford's average high is 72. Temperatures will continue to trend warmer by Thursday as high pressure strengthens off the coast and winds becomes more widespread out of the east. This should result in further bump in temperatures with the most notable jump around Roseburg and North Bend with an anticipated high of 83 and 75 degrees respectively on Thursday. This warm up will push highs well above their normals for this time of year. The thermal trough will move farther inland on Friday with sea level pressure dropping about 10 mb east of the Cascades and the 1000-500 mb thickness' rising over locations farther to the east as well. These days are usually some pretty warm days and the temperature forecast shows this with some highs potentially hitting 90 degrees. The NBM gives Medford a 15% chance of hitting 90 and Roseburg a 40% chance of hitting 90 on Friday. Not much will change on Saturday, although the temperatures might trend down a degree or two. It's worth noting that the NWS' heat risk algorithm is showing an elevated heat risk for populated areas on Saturday, perhaps due to the unusually warm high temperatures for this time of year. Given that low temperatures are falling into the mid 50's, this elevated risk seems overdone. Towards the start of next week, the NBM is predicting a 5% chance of precipitation across sections of northern California as a weak short wave could be moving through around Sunday evening or Monday evening. To elevate the thunderstorm threat, we pushed the probability of precipitation higher for those times. Any shortwave this time of year will have that threat of kicking off thunderstorms around the forecast area. Towards the middle of next week it appears high pressure will still remains in control. Temperatures have a higher probability being warmer than normal versus cooler than normal for the middle of May. -Smith Marine Updated 215am Wednesday, May 8, 2024...A thermal trough will expand strong north winds and steep to very steep seas northward today. Worst conditions are expected south of Cape Blanco with gales and very steep, wind-driven seas this afternoon through early Thursday morning. Gusty north winds and very steep seas are expected north of Cape Blanco. Current models show a high chance (55 to 100%) for north gales from Cape Blanco southward, highest (70 to 100%) beyond 5 nm from shore south of Gold Beach. The thermal trough will weaken Thursday, but lingering steep to very steep seas are possible. Lighter winds and seas expected Friday into the weekend. - Spilde/Hermansen NOAA Medford OR Office: Watches - Warnings - Advisories OR...Freeze Warning until 10am PDT this morning for ORZ024-026.
