Area Forecast Discussion National Weather Service Medford OR 201pm PDT Sunday Mar 23 2025 Dry weather is likely the rest of the afternoon through at least Tuesday afternoon. An upper ridge will build into the area this afternoon and will amplify Monday night into Tuesday in response to an upper trough digging in the eastern Pacific. It will be warmer weather Monday and Tuesday, with Tuesday being the warmer day of the two. Afternoon temperatures will be warmest Monday and Tuesday. The forecast high in Medford will be in the mid 70s Monday, low to mid 70s for most interior westside valleys, and 60- 70F over the East Side, which is 10-15 degrees above normal. Tuesday, however, the core of a thermal trough will be moving inland and these are usually the warmest days. Model guidance shows H85 temps peaking out around +15C. NBM is showing 78F currently, but the multi-model ensemble is showing a 75% chance of 80F or higher. So, we have gone with 80F for the official NWS forecast, which would tie the March 25 record of 80F set in 1997. Other records that will be challenged Tuesday will be 73F at Klamath Falls (1960), 78F in Montague (1960), 73F in Roseburg (2015), 74F in Mt Shasta City (1997). There's good agreement, we'll head back into an active pattern by the middle of next week as an strengthening upper trough and a front marches towards the coast. This will follow a couple of days of dry and warm weather. Of some concern is there could be a significant change in the air mass following the brief period of warm weather, and there are some signs of convective feed back being depicted by the models along the Cascades Wednesday morning, then migrating northeast Wednesday afternoon due to a southwest steering flow. Also convect feedback is also showing up west of the Cascades, but away from the coast. Additionally The ECMWF (European Centre for Medium-Range Weather Forecasts) EFI (extreme Forecast Index) is also a bit concerning. If the pattern being forecasted was in the summer, it would result in thunderstorms. Therefore we'll keep a slight chance of thunderstorms in the forecast. In addition, winds will increase along the coast. Shasta Valley and eastside Wednesday. Right now, winds st the coast should remain below high wind warning, but they could get approach advisory criteria in the Shasta Valley and east of the Cascades Wednesday afternoon and evening. One thing to note: Models are showing a weak shortwave disturbance skimming the coast and western portions of our CWA (County Warning Area) Tuesday evening and night, and the deterministic GFS (Global Forecast System) shows some showers breaking out in western Siskiyou County and portions of SW Oregon. Models suggest instability will be marginal at best, therefore the chance for thunder is low, but not zero. We can't completely rule out a shower or two over there after 5pm Tuesday into Tuesday night. The rest of next week into next weekend looks cooler and unsettled, but there's nothing to suggest there will be any impactful weather. The upper trough is expected to be centered off the Washington/B.C. coast with a series of shortwaves rotating around the base of the upper trough and moving in from the southwest into our area. Therefore it's likely we'll have showers over a good portion of the forecast area, with most centered along and west of the Cascades. We could catch a break in the weather Saturday as weak ridging builds in, but that won't last long with another front pushing into the area Saturday night through Sunday. Ensembles are still showing an active, wet period during the first week of April. We'll be keeping a close on that since river levels will be running high with some spring snow melt and additional rainfall. -Petrucelli Marine Updated 130pm Sunday, March 23, 2025...A weak front is resulting in steep seas for most areas this afternoon, with advisory level winds occurring north of Bandon. Conditions will gradually improve from south to north through this evening. A weak thermal trough develops tonight and winds will veer to northerly tonight into Monday. Seas will build some south of Cape Blanco in response. North winds may reach Advisory strength from Cape Blanco to Gold Beach during Monday afternoon and evening. Winds ease on Tuesday, then quickly ramp up on Wednesday ahead of a strong cold front. Hazardous conditions are likely to return Wednesday into Thursday with southerly gales and very high seas possible. The outlook is for another similarly strong front in the latter portion of next weekend. -DW/BR-y .BEACH HAZARDS...Updated 200pm Sunday, March 23, 2025...Beaches along the southern Oregon coast will have a moderate risk for sneaker waves starting late Monday afternoon and going through Tuesday morning. The highest risk will be for west facing beaches, especially during early to mid-morning on Tuesday. During this time, a west-northwest swell of 5 to 6 ft at 11 to 13 seconds is expected to combine with a long period west-northwest swell of 2 ft at 20 seconds building to 6 ft at 17 seconds. During Tuesday afternoon, the threat is anticipated to diminish with a decreasing swell period. Sneaker waves run up significantly farther on beaches than normal, including over rocks and jetties. These waves can suddenly knock people off of their feet and quickly pull them into the cold ocean waters, resulting in serious injury or death. Waves may also lift driftwood logs, trapping anyone caught underneath. NEVER turn your back on the ocean! NOAA Medford OR Office: Watches - Warnings - Advisories OR...Beach Hazards Statement from Monday afternoon through Tuesday morning for ORZ021-022. CA...None. PACIFIC COASTAL WATERS...Small Craft Advisory until 5pm PDT this afternoon for PZZ350-356-370-376. |
