@ThierryGooseBC @lumby2vernon @environmentca There’s trees surrounding the compound. Sounds like wind flow may be impacted in certain areas. That can cause a degree or two difference in the right conditions.

[Cape Breton Mesonet @CBmesonet]

@ThierryGooseBC @lumby2vernon @environmentca This is a tough one. Lytton RCS has triplicated temp sensors, and they are all within about 0.1C. You have to consider that different areas of the compound may heat up more than others. Also, the NAV can station uses a different type of sensor

[Cape Breton Mesonet @CBmesonet]

@ThierryGooseBC @lumby2vernon @environmentca Hope there isn’t a mouse nest in the Lytton RCS Stevenson’s screen 😛

@mattdagley No need for power to be cut to the entire feeder of 5,000+ customers. Outage could be isolated using one of many switches along Oxford St, or a recloser if any were installed. @nspowerinc why does feeder 104H-413 not have any reclosers along the expanse of this very large grid?

[Cape Breton Mesonet @CBmesonet]

@mattdagley Terrible to have 5,151 customers on a single feeder (104H-413). Typically a feeder only has 1000-2000 customers. This is one of the most unreliable grids on peninsular Halifax. It’s too large. @nspowerinc why is it so large? What’s being done to improve reliability of 104H-413?

[Cape Breton Mesonet @CBmesonet]

@nspowerinc still waiting for a response on this. The Oxford street distribution line is out once again

[Cape Breton Mesonet @CBmesonet]

@mattdagley This particular distribution line (Oxford Street) has serious reliability problems. By far the worst in peninsular Halifax. @nspowerinc what is being done to address this? Why are there no reclosers on this line?

Another historic day: this time in eastern Nova Scotia. Sydney set a new October record of 27.4°C, breaking the old record of 27.2°C in 1881. Records began 1870!

Ingonish Beach also set a new October record with 29.6°C, breaking previous record of 28.5°C in 2010 #nswx

[Cape Breton Mesonet @CBmesonet]

Widespread temperatures above 30°C in Nova Scotia New Brunswick today

Windsor unofficially broke the October Nova Scotia record with 31.8°C. Previous record 31.1°C at Halifax in 1930

The Oct 1930 heat event was historic, which makes today’s temps all the more impressive! #nswx

@Pat_wx @ThierryGooseBC An important note: the Maritime provinces saw a well above normal mean maximum temps, but the air was so exceptionally dry all month that nights were some of the coldest in more than a century. Very rare for the modern climate.

‼️HISTORIC HEAT IN EASTERN CANADA‼️

🌡️38.6°C Miramichi, NB, only 0.8°C from the NB all-time record!

🌡️38.1°C Maple Plains, PE = ALL-TIME RECORD for PE!

🌡️36.7°C Badger, NL = ALL-TIME RECORD for NEWFOUNDLAND.

More data with help of @Pat_wx, @CBmesonet & @rcbstormpost. #NBstorm

[Thierry Goose @ThierryGooseBC]

🌡️35.3°C Goose Bay, NL, monthly record tied.

It ties the August Labrador record set at the same station in 1996.

The August provincial record remains at 36.7°C, set in Botwood and Wooddale Bishop's Falls in 1976.

Monthly record also in Mary's Harbour with 34.5°C.

[Cape Breton Mesonet @CBmesonet]

@ThierryGooseBC @Pat_wx The current airport station and the original downtown location are quite close. That’s what makes this station such a good RCS

[Cape Breton Mesonet @CBmesonet]

@ThierryGooseBC @Pat_wx All time record at Miramichi is 38.9°C in 1935. The community was called Chatham (Chatham downtown, then Airport) before amalgamation.

[Cape Breton Mesonet @CBmesonet]

@NSWeatherCentre Yes, that’s accurate. The station is located inland a few km’s, and the sea breeze takes longer to get there. The ECCC station at Ingonish Beach reached 36.2°C just before the sea breeze came in.

[Cape Breton Mesonet @CBmesonet]

@NSWeatherCentre That 38.1 reading from MacKay Siding is an error. Station has been removed from the website until NS agriculture can determine the issue.

Textbook example of Sydney meso-low today. Hourly animation 10am—6pm as easterly marine layer holds steady on E side of CB Highlands (Ingonish Beach). Meanwhile, Sydney area enjoys hottest day of the summer thus far in W flow on S side of low, reaching 32.3°C (90°F) at AQY #nswx
