Yeh.
8:53 PM. Quickly checked the weather. Remembered to, this evening!
Earlier I had viewed the Fingal Clear Sky Chart, prompted by several email notifications from Clear Sky Alarm Sky.
Clear in the early part of the evening.
Off to EC, Environment Canada for St Thomas.
The current conditions, observed at the London Int'l Airport, as of 8:00 PM EST Saturday 26 November 2022, were noted as:
- Partly Cloudy
- 6°C
- Condition: Partly Cloudy
- Pressure: 101.4 kPa
- Tendency: Falling
- Temperature: 5.7°C
- Dew point: -2.0°C
- Humidity: 58%
- Wind: SSW 21 gust 31 km/h
- Visibility: 24 km
I copied today's and tomorrow's information from the day-by-day predictions. The forecast had been issued at 3:30 PM EST Saturday 26 November 2022:
Detailed Forecast
Tonight - Clear. Becoming partly cloudy overnight. Wind southwest 20 km/h becoming light early this evening. Low plus 4.
I often tell people to pay attention to the indicator circles from the Environment Canada weather web site—they are accurately used. Moon, stars, and a cloud... Hmm.
Sun, 27 Nov - Cloudy. Periods of rain beginning in the morning. Amount 10 to 20 mm. Wind east 20 km/h becoming north 20 late in the afternoon. High 6. UV index 1 or low.
Sun Night - Periods of rain ending in the evening then cloudy. 40 percent chance of showers overnight. Wind northwest 20 km/h gusting to 40 becoming light in the evening. Wind becoming northwest 20 after midnight. Low plus 1.
The high barometric pressure I had also noted on my (new) barometer.
Checked Clear Outside, CO:
It was showing red everywhere. Triggered by 100% high cloud. But I was not seeing that...
GTS:
It too was showing lots of cloud... But I could see stars naked eye. No obvious cloud to the east or south.
I adjusted the criteria options. Clouds remained the constraining factor.
Visited Astrospheric. Been a while...
The chart from Astrospheric was quite similar to the CSC. Clear early in the evening.
I examined the temperature line graphs. The air was within a couple of degrees of the dew point later on. Would need the dew heaters running, particularly with the large glass...
Could not figure out how to switch to Metric.

Wasn't paying close attention at the time.
Missed the rain forecast for Sunday...
Missed the poor seeing indicator...
