A cold front is bringing widespread wetting rain across the area

this afternoon and evening. After the front moves through overnight

the rain will transition to showers. There is a 20-30% chance for

thunderstorms Tuesday, although any lightning  strikes will be

accompanied with strong showers. All told we are  expecting around

1-2" of rain between Monday and Tuesday.

A stalled low will bring steady rain through mid week. Widespread 

coverage and bountiful rainfall expected for mountainous terrain.

Wet conditions forecasted  through Thursday morning. A drying trend

to returns late next week.
