KEY MESSAGES

* Dry weather and slightly above normal (5-10 degrees) temperatures expected today.

* Near or slightly above normal temperatures expected for much of the week.

* Low chances (5-15%) for rain expected on Monday from the coast to the Cascades as a low shifts south offshore.

* Chances for rain showers increase Wednesday and Thursday for areas from the Cascades east and across Northern California.

DISCUSSION

Mild and dry weather is expected today. Areas of morning low clouds are expected along the coast, in the Umpqua, and in the Grants Pass area. High temperatures will be around 5 to 10 degrees above normal.

Tonight and Monday, a low pressure system moves shifts southward off the coast. However, models continue to show that this low will remain well offshore and will move south of the area on Tuesday, before gradually moving inland late Wednesday over southern California as a cut off low. As it moves inland Wednesday night and Thursday, it will gradually track northeastward into Nevada.

As the low nears the area but remains offshore on Monday, there are only very low chances (10-15%) for light rain (generally amounts of a trace to less than 0.10 inches), mainly along the coast and inland along and near the Cascades, Siskiyous and mountains in western Siskiyou. Otherwise, expect dry but cooler (near normal) conditions on Monday.

As the low moves inland to the south and southeast, models and ensembles are showing wrap around moisture and showers developing across northern California and from the Cascades eastward on Wednesday and Thursday. The National Blend of Models has trended higher with precipitation chances (40-70%) in Modoc and southern Lake counties. For other areas, from Cascades east and into Siskiyou County, expect lower chances (15-40%) for light showers. Current models also indicate weak instability with a low chance (10-15%) for thunderstorms in Modoc on Wednesday afternoon. Rainfall amounts are likely to be light (0.10 inches or less) except in the Modoc and southern Lake counties where rainfall amounts of 0.10 to 0.25 inches are possible Wednesday and Thursday.

Tuesday through late in the week, temperatures will be mild with highs near to slightly above normal.

AVIATION...18/06Z TAFs

Chances for periods of MFR levels remain in the forecast for North Bend, but have so far not materialized. Satellite shows clouds banking against the Umpqua divide, with MVFR levels possible at Roseburg. Any clouds that reach Roseburg would likely clear out by the afternoon. Similar banking is also possible in the Rogue Valley but right now those ceilings do not look to reach the Medford terminal. An approaching low pressure system has additional chances to bring lower ceilings to the Oregon coast towards the end of the TAF period. -TAD
