Area Forecast Discussion National Weather Service Medford OR 859 AM PDT Tue Apr 30 2024

UPDATE
The weak front and upper level trough are passing onshore this morning, with very light showers along the coats and into the Umpqua Basin. The rest of the area remains mostly dry, although a few light sprinkles are not out of the question anywhere along and west of the Cascades. Meanwhile, cooler temperatures did result in some areas of freeze in the Illinois and Applegate valleys this morning, but increased clouds and sunrise have brought these temperatures up, so the Freeze Warning has been ended early. A few other updates were made to the forecast to bring it in line with the current observations, but no major changes were necessary. See the previous discussion below for more details on this and the rest of the forecast. -BPN

AVIATION
30/06Z TAFs......

For the most part, expecting VFR conditions at the terminals through this cycle. There may be times when ceilings approach MVFR but generally expecting this to be the outlier. Perhaps the biggest uncertainty will be whether rainfall occurs at any of the terminals.
Showers will be around today, but confidence is low on when (or if)
this may occur. Otherwise, this afternoon will be breezy, especially on the eastside where Klamath Falls could see wind gusts around 25 knots.

MARINE
Updated 800 AM Monday, April 30, 2024...Seas will be hazardous to small craft through this evening with a combination of wind-driven seas and northwest swell. A surface low pressure will move inland today with high seas building to a peak this evening. A weak surface high will move in over the waters Wednesday with moderate north winds, highest south of Cape Blanco. Then, another front will move through the waters Wednesday night and onshore Thursday with winds and wind wave dominated seas likely reaching small craft advisory levels. A break with calmer conditions is expected Thursday night into early Friday. A series of fronts is likely to follow Friday into early next week with stronger winds and building seas with multiple chances for rainfall.



PREV DISCUSSION... /Issued 315 AM PDT Tue Apr 30 2024/

DISCUSSION...Spring continues to be spring-like this week, with persistent northwest flow and a progressive pattern leading to changing conditions each day. A series of fronts will move through the region, bringing wet and cool conditions with drier, warmer breaks in between each system.

The first trough in this series will slide north of us through WA State/northern OR today. We're on the far south end of this, so as far as precipitation goes we're expecting light, on-and-off again stuff in Coos, Curry, and Douglas counties as well as the south OR Cascades. Snow levels are in the 2,500-3,500 foot range, but snowfall will be light overall, with light snow in the southern OR Cascades (generally under an inch up to 2-3 inches over the peaks) and a dusting possible in the Klamath Mtns. in east Curry/west Josephine. With plenty of breaks in the clouds allowing heat to escape from the lower levels, especially in the southern and eastern portions of the region, lows this morning will be chilly. The Freeze Warning in the Illinois Valley (Josephine County) looks to be on track, as both the temperature and dewpoint have dropped into the mid-to-low 30s at the airport as of writing this, with further cooling to the low 30s expected a little later this morning.

As the shortwave exits to the east later today, showers will quickly taper off late this evening, and cloud cover will further break up and clear overnight. This will result in another chilly morning Wednesday followed by a warmer (compared to today's highs)
afternoon. The next system will already be approaching by late Wednesday afternoon/evening, however, so high clouds will begin moving in and preventing the day from being completely clear.
Light precipitation looks to start at the coast Wednesday night, spreading ESE overnight into the morning, with light lingering showers into the afternoon. This system will be slightly stronger and dip further south than today's, resulting in more areas seeing precipitation in southwest OR. Precipitation will remain on lighter side for the most part, with more moderate rates over the Cascades and Curry County mountains. Another couple of inches of snow are expected over the Cascades, and light snow above 4,500 feet or so is possible (30-50% chance) in Lake and Klamath counties Thursday morning, including along Hwy 97 north of Chiloquin or so. Light amounts combined with warmer roads and marginal temperatures (high 20s to low 30s) will make it unlikely for snow to accumulate on roadways for the most part, however.

Another transient ridge builds into the area late Thursday into early Friday, resulting in another brief dry period. Another, stronger, system quickly dives down from the Gulf of Alaska Friday morning and resumes wet weather in the region as it moves eastward into early Saturday. Ensemble tools indicate much more moisture available to this system, with widespread, moderate precipitation through large portions of the region. On-and-off again precipitation looks to continue through the weekend, and odds are wetter, cooler weather will continue next week. -CSP
