Chance of Thundershowers Sunday – Gradually returning to Hot and Dry

“Most of the heavy showers have moved out of the region.” Special weather statement ended.

I’m back! :)

Tons of unstable air and moisture out there has prompted a special weather statement from Environment Canada.

10:52 AM PDT Sunday 26 July 2015
Special weather statement in effect for:

  • Inland Vancouver Island

Brief heavy downpours and small hail likely today.

A cool upper trough has descended upon the South Coast early this morning. This unstable weather system will generate local heavy downpours of 15 to 25 mm per hour throughout the day. Isolated thunderstorms producing small (pea sized) hail are also possible this afternoon.

The public is advised to monitor future forecasts as warnings may be required

The activity is all over the place on the models, so it is hard to pin down where these thundershowers will be.  So you will simply have to be prepared for all or nothing through the morning and early afternoon.

Here is the lightning/thunder map from the model showing chances all over the Island for thundering. :)

The chances for rain fades and pulls back to the hills by evening.

Focused on us on Monday.

It will mostly dry out Monday, however, there is a strange little patch of rain right on top of us Monday afternoon.

This might be thundershower type activity but there is no such chance on the model so probably just spotty rain.

We should be completely dry by Tuesday and warming into the mid-to-high twenties again and higher through the end of the week.

Wildfire ratings knocked down for now.

The good news is that even though we are still at High, the fire danger rating for the whole province has taken a much different tone at least at this moment.

Long range looking dry and hot again.

The super long range forecasts have us returning to a dry and hot pattern through the first week of August.

Have a great Sunday!

 

Special: very localized downpour on Tuesday

Even though I am on the shore of the Columbia River in Oregon (near Hood River), I have been hearing sbout the downpour yesterday in Port Alberni!

Sounds quite dramatic including videos posted on facebook.

it sounded to me like a localized thundershower type of event and the data bears that out thanks to our multiple stations in the Valley.

Here are the three graphs from the Islandweather stations for Alberniweather, Alberni Elementary and Maquinna Elementary.  Alberni obviously “got it”.  Note the scales are different so the bars are not proportional.

The official reading at the airport is only 0.8m.  This kind of thing is not unusual at this time of year, but it is always a bit of a surprise.

Love this kind of stuff.  Even when I am 2000km away. :)  feel free to post youtube video in the comments and Ill repost them in this post.  Ill be back Sunday.
