After two days in the 40s, a highly advertised warm up arrives this weekend. Sun returns tomorrow with a northwest wind at 10 to 20 mph. Clouds will lower and thicken up on Friday as the leading edge of some mild air tries to move in. Showers develop late in the afternoon and at night. Clouds break for sun on Saturday as temperatures soar into the 50s both days this weekend. A cold front on Monday brings a few additional showers followed by a return to winter cold (30s) by this time next week. Snow is possible Wednesday. The forecast rarely remains the same looking out to day 7. But a couple of inches are possible if everything pans out just right.
