March 2013 General Disco

With the next week looking to be very cold for March standards, I decided to look through MKE's climate data and see how many times there has been a sub 20° high and sub 10° low between March 15th-31st. As you can see this is pretty rare especially if you take out the pre - 1900's data. Sorry for the bad data plot.

Wow! I never even thought of this! Nice work! Looks like Wednesday will come close.

Snow Depth in the U.P. right now ranges from 10 to 60 inches. yes, there is an incredible reported depth of 58" in Marquette county somewhere (19" in downtown Marquette but 43" at the NWS in Negaunee)...and over 50" in Ishpheming. Outside of those high (60") and low (10") areas, Id say the average depth for most of the UP is 2-3 feet. It is heavy and waterlogged and there is no warmth in sight. Im thinking the may see a record late melt.

 

Meanwhile here the 2nd straight colder than normal month is all but a lock. If all the snow doesnt melt tomorrow (depending how warm it gets) we will have at least a T  on the ground all week.

Someone may have mentioned it earlier, but it's not very often that you get to March 17th with only one tornado reported for the month. (EF1 in Glascock Co. GA 3/5). If the deep South doesn't get an isolated one tomorrow, the streak could be extended for a few more days.

Incredible when you really think about it.

Looks like the storm track is going to stay suppressed way to the south the whole rest of the month.  This winter is just cruel. 

 

It's cruel, but fwiw, the 18z GFS Ensembles generally flipped to a potentially interesting look of a GLC for many next weekend.  Will Angrysummons post in the med/long range discussion be right that the constant suppression the models are showing will be wrong?

I noticed that about the 18z. The models are never right, so I don't know why some get so bothered by the long range. i look at it like this. Colder than normal temps likely? That means better than average chance of late season snow. It could be suppressed or it could cut or anything in between.

 

You know what would be a good test/study next winter? Take the 00z 16-day GFS forecast for a given city every 3rd day or so and document it, then follow it up with the actual weather conditions. I can 100% guarentee you you will have periods the LR GFS said bone dry that are snowy, and very stormy periods that end up quite dry, etc. We already know the models are bad, but i would be willing to bet actual raw model data compared to surface weather obs would be even more dreadful than most realize (outside of 3-4 days out).

lol 0z GFS for next Sunday. Would be nice of course, for those of us here who like that sort of thing...in late March.

 

That being said, as I said a couple of pages back, I think this is something to watch for portions of the sub-forum.

 

Watch the blocking be slower to break down and it ends up being a whiff to the south....on March 31.... :axe:

I was looking for CPC's March outlook, and found their original one made on Feb 21. What a failure. At least their last update at the end of Feb was better.

 

They factor AGW into every forecast according to the site. So since the world is 0.8C warmer...all long range outlooks are warmer than average. Look at the next year of outlooks.... All above normal.

Comparing the March 6-18th time period between 2012 and 2013 is absolutely astounding.  The mean temp last year on the 17th and 18th was 68!  Our HIGH will be 30 degrees less than the mean temp last year at this time.  Incredible.

 

Here's a comparison between last year and this year for that time period from my weather station...

This month has a good chance of finishing below normal at YYZ for the first time since March 2011. That's 23 consecutive months of above normal temperatures for Toronto.

The month will make 5 out of the last 8 months being at or below normal for my location.

February 2013, November 2012, September 2012, April 2012 and April 2011 were also below-average at YYZ by at least 0.3C if you go by daily mean temps. There were a few more months in that time span that were technically below-average, but only by a tenth of a degree. Though clearly the trend has been overwhelmingly warm since winter 2010-2011 with positive temp departures blowing any negative ones out of the water.

Looks like the 12z GFS follows it up with a nice hit for us.
