PM Update: A balmy Halloween evening, gusty showers towards morning

* Wind advisory western areas midnight to 8 a.m. *

7 p.m. update: A band of light, hit-or-miss showers is pushing through the region from southwest to northeast. It’s poorly timed for trick-or-treaters (wear a hood or carry an umbrella), but should take about an hour to pass.

From 5:20 p.m.: Trick-or-treating weather is quite enjoyable this evening, with much above normal temperatures and the rain/storminess well to our west. In the pre-dawn hours, winds really whip up and showers enter the region. Friday morning may well be a bit stormy, before gradual clearing Friday afternoon.

Through Tonight: Temperatures hold in the mid-to-upper 60s for much of the evening, meaning trick-or-treaters can leave the heavy coats at home. It’s a bit breezy, but the big winds hold off until after midnight, ramping up towards morning. That’s also when rain chances increase – rising from about 30 percent by 2 a.m. to 60 percent by 6 a.m. Overnight lows are mostly in the low-to-mid 60s. Winds are from the south – initially around 10 mph, but increasing to 15-25 mph towards morning with some gusts in the 30-40 mph range (higher in the mountains). Rainfall amounts are around 0.10, with some higher amounts west of town.

Tomorrow (Friday): Gusty showers, and even the rumble of thunder are likely in the morning…so the commute may be slow. By noon, most of the rain should be east of the region, with sunshine beginning to emerge. Highs range from 70-75, but it’s windy, with breezes out of the southwest at 10-20 mph, sometimes gusting over 30 mph.
