Indoor Temperature Graph During Rolling Power Outages

Monday, February 22nd, 2021 6:44pm CST
Inside Temperature 2-15 to 2-16

This is a graph of the temperature inside our house from 2/15 12:00AM to 2/16 6:00PM. It was recorded by a piece of equipment in an upstairs closet, which is normally closed. The temperature inside of the closet is typically about 5°F to 7°F warmer than the rest of the house. It showed ~49°F the morning of 2/16, when our downstairs thermostat showed 44°F.

Some notes:

Inside of the equipment closet, our backup battery/UPS kicked in at the first loss of power and generated some extra heat for about 45 minutes until the battery drained. It recharged for an hour the next morning once power returned and ran for another 45 minutes when we lost power again, which slightly slowed the closets heat loss. We gave up and turned it off after that.

Our hot water heater (in the attic) burst shortly after power returned around midnight on 2/16 when the closet temperature was showing 51°F.

After noon on 2/16, the doors were opened and closed to the room and closet, which skewed the graph a bit when the outages were shorter and we started to build heat again.

February 2011

Monday, February 28th, 2011 9:07pm CST

For the shortest month of the year, the second month of 2011 certainly brought some diverse weather conditions to Plano:

  • A 44mph wind gust on 2/1
  • A wind chill of -5 degrees on 2/1
  • 101 hours 10 minutes continually below freezing (2/1 4:26am – 2/5 9:36am)
  • A low temperature of 12 degrees on 2/2
  • 9 inches total snowfall (2/1, 2/4, 2/9)
  • A high temperature of 82 degrees on 2/18

The one area lacking from the above list is measurable precipitation/snow melt, which amounted to only 1 inch.

UPDATE – Due to time requirements, we have stopped publishing these forecasts.

PlanoWeather.com will soon be providing forecasts created with WXSIM – Interactive Local Atmospheric Modeling System. WXSIM is a very unique software package – over 25 years in the making – for modeling, forecasting, or simply studying weather. Multiple forecasts will be generated daily and displayed on PlanoWeather.com alongside NWS forecasts. A comparison page will also be added for determining accuracy between WXSIM forecasts, NWS forecasts, and actual observed temperatures.

Here is the text version of the first forecast generated by PlanoWeather.com:
