This article would make sense in that respect since it would be logical for more marine influence to contribute to a low of 14 at Logan during an arctic outbreak, as opposed to what would have been 12 40 years ago. 1 Link to comment Share on other sites More sharing options...

While I agree that our warming is contributed to warmer overnight lows there is actually strong influence by a warming ocean on this. If you think about it, a warmer ocean yields greater low-level moisture. This is one reason why I think we've seen an increase in cool season severe events (especially closer to the coast) the past several years. The warmer waters are yielding greater low-level moisture which in turn is yielding greater low-level instability. And with the warmer oceans and higher concentration of low-level moisture you're decreasing the efficiency of radiation. H20 is a stronger heat trapping gas than CO2. But yeah...this process will have a much stronger influence on nighttime as opposed to daytime. This is because H20/CO2 does not absorb shortwave radiation emitted by the Sun that well, but they do absorb longwave radiation emitted by the Earth very well. (Note: I know CO2 does...not sure if this is true for H20 as well. Don't remember). Link to comment Share on other sites More sharing options...
CoastalWx Posted July 20, 2022 Share Posted July 20, 2022 Warmer summers have been brought to us by dews and its effect on night lows I think. Part of that is likely due to warmer waters off the east coast. But it’s also been a favorable pattern over the last several summers to bring the warmth and humidity up the coast. 1 Link to comment Share on other sites More sharing options...

It’s also not necessarily the lack of snowfall. That has increased. I think they meant snowpack. I’ll have to dig into the data to see for myself.

Might be a shot in the dark but I wonder if the Gulf of Mexico has influenced this as well. Waters in the Gulf of Mexico have been above-average and also warming even earlier. This could explain why we've seen some stretches the past decade where we're getting some relatively high dews earlier on in the season. It might not be that far-fetched of a thought...the Gulf of Mexico has a significant influence east of the Mississippi. 1 Link to comment Share on other sites More sharing options...

40/70 Benchmark Posted July 20, 2022 Share Posted July 20, 2022 I may be wrong on this, but I feel like global warming would have more dire consequences faster if it were not so heavily weighted in nighttime mins. This is why I feel like sometimes there is a contingent of folks that overstate and catastrophize the impact. I understand that eventually it will matter more, but this is probably why our snowfall hasn't suffered to this point (well, everyone's except mine)....the fact that it radiates to 15 instead of 10 on a clear night isn't exactly a deal-breaker. However, the increased insolation that is not emitted does in fact result in less snow cover via a larger window of time for melting. Link to comment Share on other sites More sharing options...
