Lower solar wind speed perhaps?
Carl, K9LA has an interesting article linking solar dynamic pressure/solar wind
speed to 160M propagation predictions.
It is found here: https://k9la.us/Predicting_160m_Propagation.pdf
Based on the historical data for the last 7 days found on the NOAA Space
Weather Center site it appears that the wind speed numbers have been trending
down, with the exception of a cluster of short spikes, over the last few days
of reported improved propagation.
The historical data can be viewed here:

As someone commented, maybe we should complain about poor conditions more
often, as the band was in good shape for DX last night!
I came on for a while from around 0300Z, and worked 22 NA stations in 18
different States . . . best DX was Texas.
Good to hear so many stations on 160m, both sides of the pond.
I'm still suffering with a high noise level, so apologies if you were one of
the stations calling me that I couldn't quite copy. OFCOM have shut down one of
my local noise sources . . . they are coming back up here tomorrow to hopefully
shut down the other one. (they have located the source, but the offending
business was closed)
