Today's Forecast

Updated Wednesday 3:50 p.m.

The rain today ended what might be considered the wettest 5-day dry streak you'll ever see around here, with two days before now with a trace of rain and other showers roaming around that happened to miss the airport. Everyone, including the airport rain gauge, will be busy counting rain drops soon as a wetter pattern takes shape for a few days.

A few scattered showers will be around this evening, then generally dry overnight with lows around 40.

Thursday will start mainly dry -- some isolated showers, but steadier rains will be developing in the afternoon and evening, with light rain continuing overnight and into about midday Friday and then scattered showers for the rest of the day. Highs both days will be around 50. This system will bring about 3-6" of snow to the mountains, which would be a good start except...

A much wetter storm rolls in on Saturday that will linger into Sunday for a rainy and warm weekend. It'll be breezy at times as well but nothing significant. The heaviest band of rain will fluctuate north and south along the state like an out of control fire hose so there could be a few hours' dry time but just count on rain with highs in the low 50s. That also means rain for much of the mountains, washing away the snow that falls Friday.

We'll see scattered showers on Monday and then perhaps a brief break Tuesday with isolated showers before light rain returns for Christmas Eve.

Long range models suggest a bit of a cooling trend for the Christmas weekend -- nothing major, but enough to knock highs down into the low-mid 40s with lows in the mid 30s. Christmas Day looks dry so far.
