Thanksgiving/Thanksgiving Night Rainfall

Here are rainfall amounts from around the city for the 24 hours ending Friday morning, November 25, 2011 at 7am.  Anywhere from a tenth to half an inch.  Thanx to the cooperative observers who report to RainLog.org

Monday’s Chilly Rain

We started out the morning at 47 degrees and cloudy and then the showers moved in.  Light to moderate rain for maybe and hour and it was chilly.  Almost like being back in Oregon!  When the clouds cleared the Catalina’s had a nice coating of snow say down to about 5,500 feet.  Here are the rainfall amounts from the nice rain yesterday morning:

Fall No Matter How You Slice It

I could also subtitle this post, “Fixin’ to be Fall.”

The Autumnal Equinox is upon us.  Striking just after midnight here in Tucson.  Specifically at 2:04 a.m.  This marks the moment that the Sun will be directly over the Equator on it’s journey south.  Of course it’s not the Sun that is doing the journeying so much as the tilt of the Earth as it goes around the Sun etc., etc. etc.  You know.  Stuff you learned in grade school science.  I will mention that “Equinox” is Latin or Greek (I can never remember which.) for “Equal Night.”  Presumably the entire globe has a 12 hour night tomorrow night.  I think it’ll be close.  Your individual equinox may vary however.

I always joke that the moment the Sun is over the Equator that you may feel a little dizzy, dogs may start barking, if you are doing the dishes you may drop one.  Which is of course silly.  I mean, who does dishes at 2:04 a.m.?

Meteorologically (probably not a word) speaking the Northern Hemisphere of our planet (including Tucson presumably) have been in the Fall Season for three weeks now.  September, October and November make up the Meteorological Fall.  The Autumnal Equinox marks the beginning of Astronomical Fall.  So.  No matter how you slice it it’ll be Fall for sure starting tomorrow.  I just hope it’s cooler than 80 degrees at Thanksgiving!

Epic Tucson Rain Not So Much in Other Areas

Here are the reports from cooperative observers from around the area as provided by RainLog.org.  You can see the Epic Rain totals of 1-3″ along the south side of Tucson, but only a few hundredths in Oro Valley.  As usual with thunderstorms and Monsoon rains, your mileage may vary.  Click on the image for a larger look.

 

Almanac for Thursday, September 15, 2011

It was an epic rain that fell on the airport and the south side of town.  4 hours of almost an inch per hour rainfall rate!  Well, almost.  We ended up with 2.84″ for the day which obliterated the old record of 1.18″ set in 1944.  This is now the wettest September on record now sitting at 5.54″ for the month and we still have two weeks to go!  The old record was 5.11″ in September of 1964.  So far for the Monsoon we have had 8.59″ which makes this the 10th wettest Monsoon in Tucson history (so far).  We also made up for the rainfall deficit for the year and are now nearly a half inch above average now!

Like I said.  An epic day for rain yesterday.

Monsoon Delivers! Rainfall Amounts for Friday, September 9, 2011

Here is a screen shot from Rainlog.org.  Just off the screen to the south is Sahaurita with over 3 inches of rain yesterday!  Officially the airport picked up .77″.  You can click the image and get a slightly larger view.

Monsoon Mania! Last Night’s Storm Totals

Widespread rain last night across the Metro.  Anywhere from a 1/4 to a 1/2″ here n southern Oro Valley to over 2″ on the far east side.  It was a wonderful night of glorious rain.  The best we’ve seen so far this season!  Here is a screen grab from RainLog.org

Monsoon Starts Well

Drier air moving into Arizona from the west means the Monsoon is going to take a much deserved break for the rest of this week.  Personally, I’d be happier if it stayed on the job, but Monsoon ain’t over by a long shot.  We have a lot to be thankful for too.  Since the first storm on July 4th, we have had widespread decent rainfall amounts across the greater Tucson area.  Most areas have received a half inch to an inch and a half.  Check it out from RainLog.org

Last Nights Storm in Tucson

A storm marched right through the middle of town last night.  Most areas in the central part of the city received around a half inch of much needed rain.  Meanwhile the northwest and south parts of town got next to nothing or actually nothing.  Well, a nice light show anyway!  Here are the numbers from RainLog.org
