Area Forecast Discussion National Weather Service Medford OR 330 AM PDT Mon Apr 21 2025
DISCUSSION
Satellite image shows marine stratus north of the Umpqua Divide and portions of northern Curry and southern Coos County. The marine stratus is likely to last through at least mid morning, then gradually burning off with clear skies by the afternoon. Dry weather will continue through Tuesday afternoon, with above normal afternoon temperatures for interior locations.
An upper trough will approach the area Tuesday evening with the trough axis moving overhead Tuesday night. Instability will be marginal at best. While convective showers are possible in portions of Modoc and southeast Siskiyou County, the chance for storms are next to zero.
The upper trough axis will move south of the area Wednesday afternoon with the best chance for isolated showers and storms also shifting southeast of the forecast area.
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 the Cascades and a slight chance of showers in western Siskiyou County and south coastal mountains. -Petrucelli
AVIATION
21/06Z TAFs...Winds are starting to clam down tonight with most areas seeing northerly winds under 10 kt. Some scattered to broken MVFR ceilings are found tonight at the coast near Coos Bay.
Other areas look to remain at VFR levels through the TAF period, with only diurnal wind changes to address in the forecast. Northerly winds will gust again tomorrow afternoon for the coast and Umpqua Basin, with the stronger winds reaching the Rogue Valley (Medford) later in the afternoon. -TAD/Hermansen
MARINE
Updated 300 AM Monday, April 21th...A thermal trough will remain in place through mid week, bringing moderate to strong north winds. Very steep and hazardous seas continue south of Gold Beach through Monday morning, and steep seas continue between Gold Beach and Cape Blanco.
This afternoon, the thermal trough will strengthen. Gale gusts are expected south of Gold Beach and within 40 nm from the shore. Very steep and hazardous seas are expected for waters south of Ophir not covered by a Gale Warning, with steep seas building in all other area waters. These conditions continue through Tuesday night.
The thermal trough weakens through Wednesday and Thursday, with steady improvement in sea conditions. Below advisory conditions may be possible for all waters by Thursday afternoon. Unsettled seas could return on Friday ahead of active weather. -Petrucelli
