Area Forecast Discussion National Weather Service Medford OR 338 AM PDT Wed Apr 23 2025
DISCUSSION
Satellite image shows the bulk of the cloud cover in northern Cal and in portions of Klamath and Lake County. Radar is showing returns in northern Cal and portions of Klamath County.
Mount Shasta is reporting light rain. Based on the radar returns, most of the precipitation is confined to central and eastern Siskiyou county early this morning. During the course of the morning, light precipitation will migrate northeast into southern Lake, southeast Klamath and portions of Modoc County.
Instability is marginal at best in southeast Siskiyou and Modoc County late this afternoon into early this evening, and we'll keep a slight chance of storms there.
Weak upper ridging builds in Wednesday evening into Thursday morning, then an upper trough will approach from the west resulting in a chance for showers and isolated storms along and west of the Cascades. The CAMS (convective allowing models) which shows radar reflectivity shows convective showers and thunderstorms developing from late Thursday morning and lasting into Thursday afternoon with most of the action along and west of the Cascades. Given the upper pattern with the upper trough still offshore Thursday afternoon typically results in increasing instability east of the upper low.
Additionally, the HRRR calibrated thunderstorms also shows the highest vales along and west of the Cascades mid to late Thursday afternoon, with storms shifting over the Cascades Thursday evening.
Friday and Saturday are shaping up to be cool and unsettled with isolated to scattered showers, with showers most frequent in the afternoon and early evening hours due to daytime heating.
The upper trough will begin to shift east Sunday with showers diminishing and becoming more isolated.
Evidence is pointing towards dry and mild weather for most of next week. -Petrucelli
AVIATION
Northerly winds have increased at most terminals this afternoon, with the strongest winds along the coast.
Wind gusts through the evening will peak at 30-35kt at North Bend, while inland sites will generally see wind gusts in the 15-25kt range.
VFR conditions will remain for inland areas tonight. MVFR ceilings have been toggling around Coos Bay and Bandon and will continue tonight. An upper level short wave will amplify as it moves across the area tonight. This will cause clouds to develop across SE sections (NE California into southern Klamath/Lake counties).
Overall, conditions likely remain VFR, though local MVFR and terrain obscurations are possible in any showers that develop, especially near the Warner Mtns. These clouds persist and showers remain possible through Wednesday morning. A slightly uptick in winds near the coast are possible tomorrow afternoon as well. -Spilde/Hermansen
MARINE
Updated 300 AM Wednesday, April 23rd...Moderate north winds will continue today, but they will be gradually diminishing during the afternoon and evening.
Winds should drop below small Craft Thursday, but seas will remain just elevated enough for Small Craft conditions to continue into Thursday afternoon.
Calmer conditions are likely Friday and Saturday with weak low pressure moving into the waters Friday and remaining there into Saturday with scattered showers. Seas are expected to remain on the low side with no marine hazards. -Petrucelli
