Here is how much it is supposed to rain in Vancouver this week

If you've been enjoying the summery weather in the Lower Mainland, the weekend forecast will likely disappoint you.

While the Vancouver weather forecast calls for a couple more days of warm temperatures and sunshine, the weekend could bring rain or showers every day. 

Starting on Wednesday (April 21), however, the forecast calls for mainly sunshine and a high of 16°C near the water with an inland high of 21°C; the evening is expected to be windy with an overnight low of 7°C.

Thursday's forecast calls for a mix of sun and cloud and a high of 16°C except 20°C inland. On Friday, the forecast calls for some showers during the day followed by rain overnight. 

Saturday is expected to see rain during the day and showers at night, while Sunday's forecast calls for a chance of showers throughout the day. 

Heading into next week, both Monday and Tuesday's forecasts call for a chance of showers.

While summer might start off with a bang in Metro Vancouver, the first half of April saw cooler than average temperatures in the region. 

Environment Canada Meteorologist Armel Castellan tells Vancouver Is Awesome that April's forecast looks cooler than average this year. What's more, he says it looks like the month will see temperatures up to 2°C below seasonal averages. 

"I think we're going to see a higher probability of seeing that continued northwesterly flow giving lower normals," he explains. 

"We don't see anomalous warmth. That's kind of why the April forecast seems pretty consistent."

Following April, however, Castellan says the south of B.C. is expected to see above-average temperatures for May and June. That said, he notes that the forecast is still showing the weaker "end of the probabilities," such as 40 to 50 per cent.
