This has been bothering me forever and I can't get an actually answer from anyone. So I am asking for the collective wisdom of the board. How/when are low temps determined for the day? Weather.com has the Ames forecast for tomorrow 7 for the high and -1 for the low. If you go to the hourly forecast the temps b/n 4AM and 8AM are -10. It doesn't even get to -1 until 11 AM.

Whatever the highs and lows are in any given 24 hour period. A majority, I would say %99 of the time the low is at night, the high is in the afternoon. In the winter however every so often you hear the local weather personality say the high today was 32....and that occurred at midnight. A few times in the winter the highs happen at night and the lowest temps for the day are in the late afternoon or evening because the colder air doesn't come through until later in the day. Sometimes in the winter the high can also happen a few hours before midnight if the temps rise though out the day. Winter is where the weird stuff happens with temps.

Usually the cutoff is midnight. Love when midnight is the warmest part of the day......

It can also vary depending on the site.

Some places, especially on a 7 day forecast, the low is specifically the overnight low and the high is the daytime high. (they often display these offset to show that)
 
Was watching the TWC just waiting for the "on the 8's" local forecast since that is really all they are good for now, and saw Cantore and I think Carfagno talking about the "polar vortex" and how it's sitting right over Canada spinning. Well.......that's not true. What is sitting over Canada is an cyclonic circulation(low pressure) that moved west from the Greenland area and displace the cold air in Canada and the northwest territories. Being almost stationary it is now funneling more cold air straight into the CUS and until it pivots on the westerlies and moves east in about a week that is what we are stuck with. This isn't the dreaded vortex that moved down from the top of the world to wreak havoc on almost 200 million people. What a bunch of tools.
