NOAA, who operates our weather satellites, recently announced that one of our polar-orbiting weather satellites will be shut down.  Such satellites usually have an average life span of 3 to 5 years, but this one has lasted more than 13 years.  During that time it has helped us track winter storms, severe thunderstorms, hurricanes and much more.  It has orbited 70,655 times, amounting to a total of 2.1 billion miles.  There are still weather satellites up there, so we’re covered, but losing one is never good.

Here is an excellent link explaining how important a role weather played in the execution of D-Day.

Here is the expected position of a cold front tomorrow afternoon-evening.  Ahead of this front, thunderstorms and rain will develop.  Behind the front, the air is about 20° colder than it was on Monday.  We can expect the cooler air to hang around for a few days, along with the possibility of scattered showers and perhaps a thundershower.  The temperature will gradually rise as we head toward the weekend.

February 22nd  is historically the day George Washington was born.  Except in 1731, when he was born, it was actually February 11th!  What? It all boils down to the fact that, in some years, February has 29 days. That’s using the current Gregorian calendar, which was put into effect in 1752, twenty years after Mr. Washington was born.  The Gregorian calendar was adopted because the previous Julian calendar, under which Mr. Washington was born, had become completely distorted in regard to seasons and Easter.  As a result, September 2, 1752 was followed immediately by September 14!!  The new calendar added 11 days and one year to George Washington’s birthday, making it February 22nd, 1732! Confusing?  You bet!  I’m still not sure which day should officially be Washington’s birthday.  Some history I’ve read about Mr. Washington suggests he continued to regard February 11th as his real birthday.

I’m still getting lots of reports about those mystery booms.  I really appreciate everyone’s input.  One possible answer is that they could be CRYOSEISMS.  A cryoseism can occur when water in the ground freezes, then expands with force.  The result can be a booming sound and shaking of the surrounding ground.  Certainly, temperatures have been cold, but I’m not sure it’s been cold enough to freeze deeply enough to freeze water under the ground.  Still, in many parts of the area, one doesn’t have to go very far underground to reach water.  Also, it’s possible the ground itself, saturated with water, is expanding and cracking.  Research has indicated that CRYOSEISMS make a booming sound and produce similar effects to regular earthquakes, but sometimes don’t register on seismographs.  Recently, some officials have gone on record saying that the booms we’re hearing might be CRYOSEISMS.

People are undoubtedly hearing something. Maybe CRYOSEISMS account for some of the mysterious booms we’re hearing, but I’m not totally convinced they account for all the booms.  The best test will be to keep listening and if the booms continue as the temperature warms, we’ll have to turn our attention to another possibility.

In the meantime, please keep your reports coming.

Stay tuned!
