| COMMENT |
|
|
|
|
|
|
| An all time RECORD low temperature of minus 9.4 was recorded on
the 3rd. The previous |
|
|
| lowest temperature had been a paltry minus 8.9 recorded twice in
1954. The early part of |
|
|
| the month was characterised by an extended period of cold
weather, which caused pipes |
|
|
| to freeze for 10 days. |
|
|
| Through
the month, the mean wind speed has been well above average (almost verging
on |
|
|
| the
long term July maximum), which is reflected with the Wind Run also being
above |
|
|
| average.
Days of Strong Wind and of Gales almost double respective long term
means |
|
|
|
|
|
|
|
|
|
|
| To summarize, it's been
cold and windy. |
