SYNOPSIS

The weather will continue to be fairly benign and unchanged from day to day this week with marine layer clouds making an appearance each evening and morning along the coast into far western valleys. Slight cooling may occur by next week as a low pressure system brushes by to the north.

..New Aviation Discussion for the 00z TAF Package

Its a benign, warm day out there today. Temperatures this afternoon away from the immediate coast are anywhere from 1 to 12 degrees warmer than this time yesterday, with 60s to mid 70s along the coast, 70s to low 80s inland and in the mountains, and 90s to 100 in the low deserts. We've seen nearly completely clear skies today following the burn off of marine layer low clouds late this morning.

Today is pretty representative of what the rest of the week will look like. Temperatures will fluctuate only a few degrees up or down each day through Thursday, albeit with slight warming in the deserts through Wednesday. Marine layer low clouds will return to the coasts and western valleys each evening through mid to late morning, followed by mostly clear skies with the occasional cumulus over the mountains or upper level clouds passing over. Afternoon breezes will be mild and seasonably typical.

Broad troughing over the northwest U.S. late week into the following week will likely lead to at least a slight cooling trend locally. The extent of the cooling will depend on trough position, which still differs between models, especially heading into the following week.
