Area Forecast Discussion National Weather Service Medford OR 234 PM PDT Sat May 4 2024

SHORT TERM
Through Tuesday morning...A low pressure system continues to bring activity across northern California and southern Oregon. Reports have indicated 2 to 3 inches of rain along the Oregon coast in the past 24 hours, as well as 4 inches of snow in areas around Mount Shasta. The main band of rainfall is moving across Klamath and Lake counties while scattered showers continue west of the Cascades. Existing daytime hazards have all expired, as elevated winds over east side areas have slowed and the heaviest snowfall over western Siskiyou County and the Cascades has passed.

Other hazards will continue through the night. Instability from the low pressure system brings the possibility of thunderstorms through the night tonight. Current chances are at 20-25% across areas west of the Cascades, with lower 10-20% chances to the east. These chances will remain into the last hours of Saturday before decreasing through Sunday morning.

Additionally, a Freeze Watch has been elevated into a Freeze Warning for the Shasta and Scott Valleys in Siskiyou County. Temperatures in these valleys are forecast to be in the high 20s to low 30s tonight into early Sunday morning. The Freeze Warning will be in place from 2 AM until 8 AM on Sunday morning. Other areas, including the Illinois Valley and the southern Rogue Valley, may see temperatures at or near freezing. But the possibility of substantial periods of freezing temperatures are low (10-20%), so warnings were not issued for these areas. Near-freezing temperatures in the mid-30s are forecast, so extra care for sensitive plants and animals may still be beneficial.

The low pressure system will follow the Oregon-California border through Sunday, keeping cooler temperatures and precipitation in the Forecast for Sunday. Snow levels are expected to rise to about 4000 feet, limiting snowfall to the Cascades and the highest terrain to the east. Thunderstorm chances are not in the forecast.

A warm front will follow behind the low pressure system on Monday, bringing another round of precipitation across the area. This front looks to be non-impactful, with some limited thunderstorm chances over Klamath and Lake counties on Monday evening. Precipitation will be highest over the Cascades, with 3 to 6 inches of snow forecast over the Cascades and unremarkable rainfall amounts over lower elevations.

Long Term
Tuesday (05/07) through Saturday (05/11)...The extended period starts as "third winter" comes to an end, and a familiar pattern of high pressure builds in. During this period of high pressure strong, gusty north winds will be present along the coast and east winds will develop inland. The warm bubble around Brookings due to the Chetco effect is expected to be on display at the end of the work week.

This diurnal pattern of wind flow will bring in drier air to the region, but the magnitude of the warmth will be limited. The current forecast calls for the heat to peak either Friday or Saturday in the low to mid 80s and overnight lows barely scraping into the upper 40s or low 50s. The reason for this low peak in high temperatures appears to be a retrograding low pressure center, which is expected to undercut the ridge as it moves in from around Utah.

AVIATION
04/18Z TAFs...Unfavorable flying conditions this morning are expected to gradually improve through the afternoon and evening as the potent frontal system passes through and out of the area. Widespread MVFR ceilings, terrain obscurations and periods of moderate rain and mountain snow can be expected. Local IFR/LIFR can occur as well, especially in times of heavier precip.
Precipitation behind the front will become more showery late this afternoon and evening, but we still expect plenty of MVFR along with areas of higher terrain obscured through this evening. Some improvement to VFR tonight, though areas of MVFR will remain. Rain showers will transition to snow east of the Cascades later this afternoon and evening as freezing levels lower to around 3000 feet MSL. -BPN/Spilde

MARINE
Updated 200 PM Saturday, May 4, 2024...Showers will dissipate through this evening, with a very low chance for a thunderstorm before sunset. Moderate west winds and steep fresh short period west swell will continue through tonight, then southwest winds increase Sunday ahead of another front that will move through late Sunday night into Monday. Seas are likely to remain elevated Monday night into Tuesday with building west- northwest swell. After that, we expect high pressure to build in mid- late next week with a thermal trough strengthening along the coast.
This will bring a return of stronger north winds and steep seas, highest south of Cape Blanco. -BPN
