SHORT TERM
(Today through Saturday night)...Showers will be numerous today through tonight, with snow levels around 3000 to 3500 feet, and highest amounts for the southwest facing slopes of the higher terrain from the Coast Range to the Cascades. Snowfall amounts will have a higher than normal degree of variability due to the showery nature of today's conditions. But, the greatest potential impact will be in the Crater Lake/Diamond Lake area, with 3 to 7 inches of new snow likely through this evening. A Winter Weather Advisory remains in effect through this evening for the Cascades and higher terrain of Siskiyou County.
There will also be isolated thunderstorms, with the highest probability near the coast of Coos and Douglas counties northward.
Precipitation amounts are expected to be highest in southwest Oregon to the west of Interstate 5, and western Siskiyou County.
A closed upper low is centered offshore from Washington and will move relatively little through this evening. With the cloud cover, precipitation, and close proximity of the low, today will likely be the coldest day out of the next 10 days. Highs this afternoon will generally be around 10 to 15 degrees below normal, approaching 50 at the coast, mid 40s to lower 50s on the west side, lower 30s to lower 40s in the mountains, and lower to mid 40s on the east side.
Showers will occur mainly through this evening, but linger into early Friday morning at the coast. The next trough is farther offshore from Washington, but will deepen/strengthen as it tracks southeast toward northern California. The impacts from this system look to occur largely south of our area Friday afternoon into the weekend. But, southerly upslope flow should bring very light or light shower activity into southern portions of Siskiyou and Modoc counties. Elsewhere, the main effect will be copious amounts of mid level and upper level clouds and the start of a warming trend, with high temperatures returning to near normal for Saturday.
LONG TERM
(Sunday through Tuesday)...There's sufficient evidence supporting dry and milder weather Sunday through Tuesday of next week.
Most locations will be dry Sunday. However, residual wraparound moisture from a departing upper low southeast of our area could bring a few showers in portions of southeast Modoc County Sunday morning. Also, a weak shortwave may produce a few drizzly late Saturday night into early Sunday morning coastal showers. Sunday afternoon will be dry for all areas.
An upper ridge will build in on Monday with the upper ridge axis over our area Monday afternoon. This will lead to dry and milder weather. Skies will be clear, although could not rule out low clouds in portions of the Umpqua Basin, Illinois Valley and Grants Pass area due ample ground moisture from the active weather today through Friday.
Dry weather will continue into Tuesday with the ridge axis shifting east and at the same time flattening out as an upper trough approaches from the west. There are some differences among the operational models regarding the strength and timing of the upper trough. The GFS is showing a stronger upper trough, but the ensemble mean shows a solution that resembles the operational ECMWF which is weaker. The majority of the ECMWF individual ensemble means lean towards dry, but some members show very light precipitation amounts. The individual GFS ensemble means show a mixed bag of dry and wet.
For now, from late Tuesday through Wednesday, we'll keep a slight chance to chance of precipitation. The probability will be highest along the coast, and across Douglas County to the Cascades, and especially on Wednesday.
Beyond next Wednesday, the evidence is pointing towards troughiness over the Pac NW the latter part of next week, leading to more cool and unsettled weather. Stay tuned.

.AVIATION (28/12Z TAFs)...More of the same today with MVFR ceilings along the coast and over inland valleys. In addition, there is a chance for thunderstorms west of the Cascades through the TAF period, although the best chances will be during the late afternoon and evening hours. East of the Cascades, wind gusts will be around 30 knots during the late morning hours and could approach 35 knots pretty easily if a heavy shower moves overhead. VFR ceilings are more likely east of the cascades.

MARINE
Updated 500 AM Wednesday, March 27, 2024..Gusty southwest winds and brief periods of gales will persist today with a high and steep swell group moving through the waters. These seas will peak at about 18 feet this afternoon. The conditions will slowly improve late tonight, although remain hazardous to smaller crafts.
By Friday night, seas will bottom out at about 7 to 8 feet before rising under the stronger northerly flow. There could be pockets of gales again in the outer waters beyond 30 nm from shore Saturday evening into Sunday under the thermal trough.
