The front will push through tonight with showers as it exits with dry cloudy weather for Sunday with the next front arriving Sunday night into Monday morning. Precipitation should ease off Monday afternoon with intermittent periods of light precipitation into Tuesday. This pattern will continue into next week with normal temperatures and May showers. Guesstimates: 4-8-? 18 mm by Sunday morning, 2-6 mm by Monday morning, 2-6 mm by Tuesday morning.

Environment Canada Guidelines:

Precipitation in the form of liquid water droplets greater than 0.5 mm. If widely scattered, the drop size may be smaller. The intensity of rain is based on rate of fall. "Very light" means that the scattered drops do not completely wet a surface. "Light" means it is greater than a trace and up to 2.5 mm an hour. "Moderate" means the rate of fall is between 2.6 mm to 7.5 mm per hour. "Heavy" means 7 mm per hour or more.
