Hi <<First Name>>,

Road Weatherlogics Beta Testing

Beta testing of Road Weatherlogics has been ongoing for just over a month. Over that time we have been able to add a number of new features based on user feedback. Here are just a few of the changes:
  • More rural roads
  • Additional graph options
  • Ability to submit driver reports
  • Improvements to the road weather forecast model
  • Additional highway cameras
  • User interface improvements
Thanks to your feedback, we are now close to being able to announce an official release date for Road Weatherlogics. Stay tuned for an announcement later this month!

If you're still interested in getting the beta version of Road Weatherlogics, just click the link below (Apple devices only). If you are an Android user, you can reply to this message with your gmail account to get a private beta test download link.

Climate Service

Frequent readers of our newsletter know that the previous month's climate summary is a regular feature. What you may not know is that the data we use to produce our climate summaries undergoes extensive quality-control before it is used to calculate monthly averages and totals. In Canada, the National Climate Archives store data collected by approximately 1000 weather stations across the country. These stations are considered to be of high quality and follow World Meteorological Organization standard. However, sometimes issues arise that cause faulty readings to be reported, or data to be missing due to communication failures. Unfortunately, this can cause erroneous values to be entered into the National Climate Archive, or even cause the data to not be reported at all.

Due to changes in practices at the National Climate Archives, only limited quality-control is now used. At Weatherlogics, we have developed a proprietary system to fully quality-control and repair this data, so it can be used by decision-makers. The graph below shows the number of temperature and precipitation values were have repaired for some major Canadian cities, this is in addition to the limited quality-control from the National Climate Archives. Repairs can include retrieving missing values, correcting erroneous values, confirming estimated values, or re-calculating incorrect averages or totals (this is not a complete list of qc procedures).



As you can see by the graphed values, we have correctly over 300 values for all six cities. Since these are daily counts, 365 values repaired would be equivalent to one full year of data. In some cases, like Saskatoon and Regina, we have repaired over 1600 values, which is equivalent to nearly 5 full years of data.

One particularly significant case we encountered was the town of Gretna, Manitoba. The National Climate Archives contains 13,163 daily values for Gretna since 1885, out of a possible 23,071 values. After Weatherlogics' quality-control and repair procedures were used, nearly 6,000 missing or erroneous values were repaired, increasing the total number of observations at Gretna from 13,163 to 19,033. This increased the percentage of available data from 57.1% to 82.5%. While this is a particularly extreme case, large improvements have also been made to the climate records of other Canadian cities, as shown by the graph above.

If you require climate data for Canadian locations, don't hesitate to contact us. We'd be happy to discuss how our quality-control procedures can improve the Canadian climate data you need.
 

October Climate Summary

It was an abnormally cold October across the Prairies, with all major cities being colder than normal. Precipitation was more variable, with some locations being wetter than normal, while others were drier than normal.
The most significant monthly value was Calgary's October precipitation total, which was the 6th wettest on record. This included 48.4 cm of snow, which is (unofficially) the snowiest October on record in Calgary. If this was indeed the snowiest October on record, it broke the previous record of 47.5 cm in 1961. At this time we remain hesitant to confirm the record due to changes in measurement techniques and missing data in previous years. We will investigate further in an attempt to confirm this record. Regardless, it was a very snowy month in Calgary!

Winter Outlook Update

The latest projections show a slight increase in the probability of an El Nino event occurring this winter. In our last update, the probability of El Nino was approximately 65%. It has now increased to approximately 70%, with a corresponding decrease in the chance of neutral conditions down to 25% (no El Nino or La Nina). The chart below shows the latest model projections for El Nino from the Climate Prediction Center. An El Nino Watch remains in effect due to the possibility of these conditions developing this winter.
