SHORT TERM...Through Monday morning (3/31)...A low pressure system lingering over the Pacific Ocean is continuing to bring active to northern California and southern Oregon, although the impacts form this system are decreasing. Southwesterly flow aloft is continuing to bring light to moderate rainfall to the Oregon coast, especially to areas south of Cape Blanco. Storm cells with 40-45 dBZ reflectivity will Probability of Precipitation up occasionally around Brookings, but no lightning strikes have been sensed since this morning and reflectivity drops quickly as these cells move over land. Lighter scattered showers are continuing to stream over inland areas.

While snow showers are continuing to move over the Cascades, western Siskiyou County, and the Mount Shasta area, road webcams and radar imagery are indicating light activity in these areas. So while caution is encouraged while traveling through these areas as active weather continues, there is no need for continuing Winter Weather Advisories. As of the posting of this discussion, these products have been cancelled.

Gusty winds are moving over elevated terrain, especially over areas east of the Cascades. Stations across Lake County and in Weed are reporting wind gusts of 30 to 40 mph. These winds are expected to continue into the afternoon but should calm quickly this evening.

The low pressure system will start to move to the south towards California tonight, and through the day Friday. While this will bring an end to widespread activity, scattered showers will still be possible as moisture wraps around the system and returns to the area from the south and the east. This will bring slight precipitation chances (25-50%) to Siskiyou, Modoc, Lake, and Klamath counties during the day. Showers will have to get past the Cascades to reach west side areas.

The pattern will start to transition from active to stable on Saturday. Northerly flow aloft will help to keep temperatures close to seasonal norms. Gusty winds may develop over elevated terrain Saturday afternoon and persist into the evening, but these winds are not expected to reach advisory thresholds right now. The week will begin with atmospheric stability and above average temperatures across the area. -TAD

Extended Discussion...(Monday through Thursday)...It will remain dry through Tuesday with milder temperatures in the afternoon for most interior locations. The ridge axis shifts east as an upper trough approaches from the west, but the front will remain offshore through Tuesday evening.

The front will reach the coast late Tuesday night and could bring a slight chance of rain to the coastal counties and Douglas County by early Wednesday morning, with dry weather likely elsewhere.

The upper trough will push closer towards the area Wednesday and the operational models show what could be convective feedback with Quantitative Precipitation Forecast fields increasing in northern Cal, Cascades and eastside. The individual ensemble members show a variety of solutions, with the majority of them keeping most of the precipitation along and west of the Cascades Wednesday afternoon and evening.

Beyond next Wednesday, the evidence is still pointing towards troughiness over the Pac NW which could carry over into the start of next weekend, leading to more cool and unsettled weather. -Petrucelli

Marine
Updated 100pm Thursday, March 28, 2024..Moderate to strong southwest winds will persist into the evening, with brief periods of gales possible north of Cape Blanco. A high and steep swell group is moving through the waters this afternoon, peaking around 15 to 18 ft today. Conditions will slowly improve late tonight as winds diminish, and while seas will gradually subside tonight, steep seas are expected for much of the day Friday.

A pattern change is expected Friday with winds becoming northerly Friday evening and increasing on Saturday. These northerly winds are likely to stick around into the first half of next week, resulting in periods of steep to very steep wind driven seas, especially south of Cape Blanco. /BR-y
