16.9ºC |
St. John's UaDK |
A southwesterly flow did not allow the overnight low to drop below 16.9ºC which made it the warmest overnight low ever observed in June since records began in 2000. However, by 23:59 NDT, the temperature had fallen to 16.1ºC, and thus 16.9ºC was not the official low temperature for the day. It was 11ºC warmer than the average low temperature. |
25 Feb. 2006 |
50-60cm snow |
St. John's |
An intense low pressure system tracked further west than forecasted bringing intense snow and violent winds to much of eastern Newfoundland. Snowfall totals were close to 60cm and wind gusts were that of hurricane strength. The 57.9cm of snow that fell at St. John's UaDK was a record for a one-day snowfall. The 54.0cm that fell at the airport was 14cm shy of breaking the record set in April 1999.

16 Jan. 2006 |
10.4ºC |
St. John's UaDK |
The same cold front did not reach the Avalon peninsula until 23:30. This kept St. John's in the warm sector of the low and the strong south-westerly winds kept the the temperature above 10ºC overnight, only falling to 9ºC at after 09:00. The overnight low temperature was 20ºC above the normal low of -10ºC. By 23:59, the temperature had fallen to 5.1ºC and thus the 10.4ºC was not the official low temperature for the day. |
15 Jan. 2006 |
15.0ºC |
St. John's UaDK |
This same weather system resulted in a high of 15.0ºC, making it the warmest January day since records began in 2000. The high temperature was 15ºC above the normal high of 0ºC. |
15 Jan. 2006 |
15.7ºC |
St. John's Airport (YYT) |
Ahead of a sharp cold front, strong south-westerly winds helped to push a warm, tropical air mass ahead of the front. This resulted in a high of 15.7ºC, making it the warmest January day since records began in 1942, beating the old record of 15.2ºC set on 09 January 1979. |
