I have no idea at this point, I learned today that my beliefs in how the atmosphere works was WRONG. The se ridge+polar vortex in Maine actually does the opposite of what I thought, it does not create a boundary for cyclogenesis, but it shreds storms.  Also we are in a fast flow pattern which makes bombogenesis more difficult to occur. La Niña also apparently doesn’t cool off the oceans like I thought, meteorology is complicated and not intuitive at all. My forecast could still be right, but if it is it will be because of the wrong reasons. I have a confession to make, I don’t really know anything whatsoever about meteorology, but I am trying to learn by making forecasts and when they bust doing a post Mortem to figure out where I went wrong. Regardless it was fun to track this storm and the post mortem analysis will be interesting.

One things that gives me hope though is often the bands push farther west than expected, which may help my forecast not turn into a total bust.

I'm riveted, waiting for your forecast

A good man, just a bad wizard.

This morning I saw you saying that yes.. but all the TV forecasts last night and this morning said very light stuff today with main action tonight and tomorrow. So there’s no way they can claim they forecast that . 

Yea I don’t think anyone had the 2 per hour quick burst. That was supposed to be over LI from what I heard this morning on TV. But we called it here with that 800-600 band sitting on LI you knew just north was getting it

They didn’t . They’re claiming that was included in their forecasts but it wasn’t . They all were saying light non road issues today with meat tonight and tomorrow

I'm afraid we have no choice but to revoke your "double O" status for the time being. Tough break, chum.

La Nina's are called such because they are the cold phase of the El Nino Southern Oscillation index.  Basically the ENSO is simply a way of determining a warm or cool phase of the Pacific Ocean equatorial coverage of thunderstorm development due to the forcing caused by warming or cooling of the equator in the Pacific Ocean.  You have different regions in which the ENSO is measured, the NINO has different locations that mean different things.  A cooling of the equator west of Mexico is a La Nina (cold phase), a warming is a El Nino (warm phase).  There are research graphics you can look up on google just for simply verifications.  Also, a La Nina favors a Southeast Ridge.  Now, while the flow does become compressed as a SE Ridge flexes against the northern stream troughs, it does not mean the flow has to remain progressive, or that bombogenesis does not occur, it just means it occurs too late for the NE CONUS.  A large boundary does develop along the NC and SC coastlines but not because of the SE Ridge but because of the natural baroclinic (difference in temperature over a short distance) develops from the presence of the Gulf Stream which is still over 65F.  Oceans do not warm or cool quickly, instead their minimums and maximums are offset compared to atmospheric climates.  Because the ocean absorbs heat or cooler air, it cools and warms at a much larger rate than the atmosphere does.  ENSO phases have nothing to do with Atlantic Ocean temperatures warm or cold.  OH the PV is not in Maine, but instead in Canada, it is rather rare the vortex even comes as far south as International Falls, Minnesota.  What has been happening in the TEXAS and OK regions is quite rare.

Why can’t we get soundings like this?

Getting off track here (as usual for me), but this image is from the UMass radar back on Feb 1, 2011, pointed vertically and rotating underneath (birdbath scan)... spectral width is plotted... notice it's very low all the way to like 7km, indicative of snowfall throughout the entire column... We got like a foot in that event, and it was puking snow.

Down at Gillette again for my wife’s turn while I wait in the car. Hit some light snow as soon as I left the house with wisps blowing across the road.  Still snow grainy very light here at Gillette 

The wife and I had our first shot yesterday at Wegman's.  Was surprised when they called Tuesday saying they still had a small supply left.  Probably many are refusing to get the shot.  Both of us had a sore arm last night, but it is slowly feeling better today.  Tender to the touch in the shot area.  Second one March 17.

I was 14 when I started to learn vigorously on my own about the weather, it was the summer of 2004, man I cannot believe that was 17 years ago, and I am 31.  I self taught everything I know about the weather, over seventeen years worth of learning.

That’s pretty cool because while I was obsessed with storms as early as age 4, I became self-fluent with NWS products and weather by age 14-15 too. Believe it or not, it seems it’s much cooler and in Vogue to be into weather in the Midwest and East than out west....
