April 2019 Forecasts and Discussions

[AbbyJr]

Yep. Almost October or November like with SW flow.

Rain shadow effect in Abby with SW flow?

Fake news...just ask the Tampa bay lightning

Both the Pens and Lightning have now won just as many playoff games this year as the Canucks. Brutal for them.

It appears that the Lightning knocked out the power in Tampa. Fork in the cup and the transformer blew. Lights went off and now they are golfing.

I meant to say when was the last time the valley had 0c in April? maybe it wasn't that long ago.

Last year. April used to have freezes every year, often more than once. I don't quite know when it started to become less common, but it's definitely not as common nowadays.

Yeah, most likely.

As usual, areas along the mountains will see the brunt of the precip.

Long range 18z still advertising a warm start to May. An extended warm spell in early May will definitely ensure those pesky cotton balls will be flying by mid month.

Could be sometime around when the global climate started shifting more rapidly, aka the mid to late eighties. Several years were the warmest on record at the time. Vancouver is part of that shift. We see less of anything to do with cold - snow, frost, summer rain, and on. The statistics clearly bear this out. One day we might all agree this is happening but I dont believe that day is here yet.

We're well overdue for an April snowfall too. Last one was back in 2011 I believe.

Eye catching headline: Winters are only going to get worse. Not sure where they're getting their info.

probably from solar scientists. from what I've read previous models for future climate predictions have ascribes 0.1% of climate change to solar forcing but we've only been able to really study the sun for the past 50 years. so it's likely those models of past climate were a bit off.

Some of the solar scientists are predicting that the current relative lack of sunspots could continue into the next cycle and we'd have a Dalton-like or Maunder-like solar minimum which means global cooling and more snow.

granted this is a cr@p shoot at this point half the solar scientists think the opposite but there are enough out there to provide for those types of articles.
while I wouldn't want a true Maunder minimum and it's associated reduction in viable farming areas, all that snow would make for some fun times on the forum

Rainfall warning for the Fraser Valley but nothing for Metro Van. Very unusual to have a rain warning in Abbotsford without one in Coquitlam.

Must just be that trajectory of the low favours the Fraser Valley.

24.5mm recorded so far today at the rain gauge in North Coquitlam.

Hasn't been too impressive over here yet but it's coming down steadily. Could possibly hit 50mm by day's end if it keeps up.

15.4 mm here so far and I'm the one with the rainfall warning. Had stopped raining for a bit but its pouring again.

For the western Fraser valley the warning does specify higher amounts near the mountains, such as Mission. Amounts will likely be lighter, possibly below warning criteria closer to Abbotsford

Fair enough. I usually do a bit better then the S sections of Abby though being a bit farther north.

Yes read all the details carefully boy before you judge
