Area Forecast Discussion

800pm PDT Tuesday July 5 2022

Showers continue over parts of the forecast area, generally from the Coast Range east to the Cascades. No lightning has occurred with these showers, even with some of them fairly vigorous, and there remains generally a 10 percent chance or less of lightning through the evening in the Cascades, Siskiyous, and foothills. Latest high resolution rapid refresh (HRRR) model data suggests isolated to scattered showers will continue in the same general area through the nighttime hours. Individual showers have produced up to a tenth of an inch of rain thus far and are moving south to north at a good clip, so brief, moderate intensity showers are possible.

Additional showers are possible tomorrow, but coverage and chances will be less (mainly 30 percent chance of showers for only the Umpqua Basin and Cascades north of Crater Lake in the afternoon). Breezy south to southwest winds are expected in the Shasta Valley and areas east of the Cascades Wednesday afternoon. Temperatures will trend warmer by about 5 degrees Wednesday compared to today, but afternoon readings will still be below normal for this time of year. Please see the previous discussion below regarding the continued warming later in the week and into the weekend. Keene

Updated 130pm PDT Tuesday 05 July 2022...An upper level trough will remain over the eastern Pacific Ocean and into the Pacific Northwest through the week. This will result in light winds with seas dominated by a light west swell. Marine stratus will be persistent through the week and fog is expected at times. A thermal trough is expected to return to the southern coast this upcoming weekend with increased north winds, especially south of Cape Blanco. Confidence is increasing that Small Craft Advisory conditions will begin Saturday due to these north winds and steepening seas. Then, gales are possible on Sunday.

With an upper low wobbling well offshore, bringing moisture and short waves up and through the region, expect additional showery and mild weather. Scattered showers are forecast mainly from the Cascades west with some isolated showers east of the Cascades. There is also a slight chance of late afternoon and evening thunderstorms from around Crater Lake and Chemult northward. Breezy to gusty south to southwest winds (gusts to 20 to 30 mph) are also expected in the afternoon/evening in the Shasta Valley and east of the Cascades. A similar pattern is expected on Wednesday, with a showery pattern, although showers are forecast to decrease in coverage. Mild temperatures will persist through Wednesday with highs in the 70s to low 80s across inland valleys.

Thursday and Friday, expect slightly warmer and mainly dry weather. The ECMWF (European Centre for Medium-Range Weather Forecasts) and GFS models/ensembles favor a persistent trough centered along the PacNW coast or just offshore. With this pattern, expect breezy to gusty southwest to west winds, especially for areas east of the Cascades. On Friday, most the ensembles favor dry weather. However, some ensemble members show an upper level shortwave moving into the area with a slight chance for showers and thunderstorms over central and eastern portions of the area. Will need to monitor this portion of the forecast and update if models trend towards the wetter solutions.

Heading into the weekend, models and ensembles show a trend towards warming temperatures as the upper trough shifts eastward and an upper ridge builds into the area. Some guidance suggests that troughing, or at least some weak cyclonic flow, is possible early next week.

AVIATION...05/18Z TAFS...A mix of MVFR (Marginal Visual Flight Rules) and VFR is expected over the coastal waters, along the coast, and into the lower portions of the Umpqua Valley with showers and mountain obscuration at a peak during this afternoon and evening. There is IFR conditions along the southern Oregon coast in the Brookings area that could last through the afternoon.

The remainder of the area will mostly remain VFR except in the presence of showers where conditions will drop to MVFR. Also expected is obscuration of the higher terrain. Showers will be at a maximum this afternoon and evening (mainly between the Cascades and Coast Range). There is also a slight chance of thunderstorms this afternoon and evening in far eastern Douglas and northern Klamath counties. Gusty southerly winds east of the Cascades and in the Shasta Valley are expected this afternoon and early evening. -Miles
