A massive arctic cold wave is heading for the midwest and east. It has
already hit the prairies with record cold and blizzard conditions with
three dead so far. A front of this strength can affect radio reception
so it might be worthwhile to tune through the bands for the next four
days.

How will this front affect the ionosphere?

It doesn't. It can cause ducting, however.

Which will affect SW how?

Not shortwave. Nice try.

It was a nice plesant warm (about 74 degrees here this afternoon,suppose
to get to about 74 degrees again tomorrow,then cooler weather for the
next few days with predictions of some rain) mostly sunshiny day here
today.I did a bunch of work in my back yard,rounding up some scrap metal
and junk I don't want to hang onto anymore.Getting it ready to haul to
the scrap metal yard on Monday,and Tuesday,and Wednesday,untill I have
it all hauled off.Really a nice day.I have 17 big trash bags full of
empty beer cans I am going to haul off too,I will use that beer can
money to buy more beer.

It's 24 degrees here. About 1 to 1.5 inches of ice has fell over the past 30
hours. Expecting another inch over the next 24 hours. Cable TV and lights
have started to flicker this afternoon, so the wires are starting to feel
the stress.

Southern California has several seasonally persistent inversion layer
situations. Besides, we're in uncharted territory regarding the
atmosphere in general; never say never.
