Forecasted temperature time period definitions

[tetraquarkneutrino]

What is time period definition for daily forecasted temperatures - Day, Night, Hi, Lo, Evening, Overnight?  What is the time period for these temperatures for a given "day"? 

For instance at my location in Michigan, the low temperature for the 24 hour period from 12am to 12am defined as that official "day" usually occurs around 6am of that "day".  Is the "Low" forecasted temperature the temperature from 6am of the 12am to 12am period defined for that official day?  Or is the "Low" forecasted temperature actually the lowest temperature from the morning of the next official "day" typically around 6am ("overnight low??").   

I have been using Weather.com so I would like to know what their definitions are but also want to know how all the major reporting channels define these.

Typically the low will occur just before sunrise and the high will occur in the afternoon. Weather conditions of course change this up but to simplify it if you were to have for example 83/62 as your forecasted high and low. The high will occur around 2-5pm (depending on the season) and the low will usually occur 3am-6am.

The low temp is usually going into not coming from. So if you happen to have a low of 58 in the morning when hitting that 83 forecast that same day the low going forward is forecast to be 62 for the next morning. So the day before the forecast would have maybe looked like 78/58 going into the 83/62.

When the low or high hits it may just be for a brief moment and not a multi hour situation.

Hope this helps.
