For the first day of September, near record lows are possible for Tuesday morning. All conditions are favorable for temperatures to plummet. Here is what we look for when we are expecting a cold night:
1. Clear skies: This allows for good radiative cooling (all the heat from the day escapes due to no cloud cover)
2. Light winds: This limits the mixing of air in the atmosphere allowing the lowest layer to cool the most.
3. High Pressure: This brings dry air. Temperatures cool faster when the air is dry verses a higher moisture content.
All three of these ingredients have come together which will result in temperatures to drop into the low and middle 40s during the end of August.
RECORD LOW: 41° degrees set in 1967 at Toledo Express Airport
