Cloudscapes in the morning
While we are sleeping tight
Are rolling by like thunder now …
18th January @ 02:46. This spell runs to around the 26th January. However it not all that different from the next one, which is @ 07:55.
By that I mean the next one is for tornadoes whilst this incoming is part way between tornadic and thunderous. All in all, three quite closely related spells so more earthquakes or tropical storms to see them out, no doubt. But that's for February.
A fine spell breaks the chain, so you'll have to wait for the nod on that one.
2:30 and presumably 8:30 am and pm, are more like tornadoes and maybe derechos than thunder. But in Britain if the resultant declinations are anything like 60 degrees south of the North Sea, it's a bad (good if like me you enjoy fireworks) time for thunder.
I believe that the recent earthquakes in and around Japan have broken the chain of tremors in the USA. Though looking at the NEIC Rat Islands is responding the east coast highs. I have the feeling that's good news unless you are a Kansas farmer.
Whatever the case, this series has now had time to settle into the normality for its spell. On the Atlantic sea level pressure chart, the occluded fronts look set for more multiple earthquakes so no tropical storms just yet.
All in all it's going to be an very interesting few days. Take great care.
And good luck. May god be with you.
