Severe Weather Signals

Hello all,

We’ve been talking about the severe weather signals for mid-February now off and on.  Here is something that Josh put together from the #RRWT.

What you are looking at are the #RRWT Lifted Index maps for the 21-25 day “outlook” compared to the SPC CFS Dashboard for severe weather.  Right off the bat, I want you to notice that the CFS Dashboard didn’t see the ‘signal’ until the 276hr – 300hr forecast. That’s a mere 11.5 – 12.5 days heads up vs the #RRWT giving a signal by all three depictions starting on January 23rd via the graphics below.

The models are honing in on severe weather even before the CFS dashboard starting on the 17th. So, looking above you can tell that the #RRWT was a good indicator during a “lull” being shown via the dashboard.

Mix that with the Southern Oscillation Index Delta, or #SOID.

Multiple variations in the sine wave above note volatility in the daily SOI numbers. That volatility translates to a volatile pattern in the United States.

Now, put it all together with the BSR depictions from the 15th to the 21st…

 

 

 

 

Bad news for those along the Gulf Coast into the Mid-Mississippi and Tennessee Valley’s.

CarolinaWxGroup Interview and More…

 

Hello everyone!

Be sure to watch my interview with the CarolinaWxGroup on youtube! Dr. Lupo had issues with his camera, but joined in on the phone.

Right now, I’m in the process of gathering data for my January verification post, which will be published in a few days…I promise!  Meeting with Dr. Lupo is at 11:30am today and we plan on discussing quite a few objectives for our future research.

December Verification

Hello everyone!

As promised, I have finally gotten around to looking at December’s #bsr verification.

Here is the BSR depiction, both surface and 500mb, for December 1st.

The surface and 500mb of what actually happened.

It goes without saying that for an 18 day lag time, the #bsr did very well! An occluded system off of Southern New England, three low pressure systems over the desert Southwest, and a clipper coming down the pipe in the Northern Plains.

Fast forward a few days to December 6th.

The BSR depicted a system in the Northern Plains with a dominate trough stretching into the Pacific Northwest aided by a dual upper level low pattern, along with a system moving into the Southeast with ridging in front.

Next is the cold shot for the 12th-20th…

 December 12th

The BSR had ridging pushing up the East coast with a mean trough over the Plains and West. This did very well to start off.

December 13th

The BSR had a strong storm system developing in the Lower Mississippi Valley that never materialized for the CONUS which skewed the next couple of days..

December 14th

 

 

December 15th

 

 

The BSR had a trough focused on the Ohio Valley with ridging off the East Coast and another trough in the West. East coast didn’t do too bad, but the trough for the West was too far East.

December 16th

 

 

The BSR had another strong system moving through the Lower Mississippi Valley to which I was warning about a severe weather event.

December 17th

 

 

The severe weather event that I thought would start on the 16th was delayed by a day. Ridging over the East coast did well, but the trough was too far East on the BSR maps.  I would think that the lag time was a day off.

December 18th

 

 

December 19th

 

Something else that the BSR keyed in on was the ULL in area of the Baja Peninsula.

December 20th

 

Early in December everyone was going nuts over the ridging in the Bering Sea which promoted a -WPO & -EPO combination and allowed the influx of cold air during the above time period. While they were doing so, I kept warning them that they won’t be happy during the week of Christmas because the warmth would return with a vengeance.

 

 

 

 

 

 

 

 

Anyway…off to work I go! If you have any questions email me at kopnfmradiowxATgmail.com!

Also, make sure you tune in tonight for a streaming show that Dr. Lupo and I will be interviewed on regarding the #bsr and #organicforecasting!

What’s All The Hoopla About??!!

Now, those that know me know I’m just poking fun with the above.  Why do you ask?  Well, the Bering Sea Rule gave us a heads up on Veterans Day! Note the key features of an ULL in South Central California, a shortwave in the Mid-Mississippi Valley, and another off Cape Cod.

Here is the WPC 500mb forecast issued yesterday evening. Note the similarities??!!

I see an ULL feature over the Baja, a shortwave in the mid-Plains, and another off New England.

Here is what the future holds in 5 day increments via the 500mb anomalies.

Tropical Tidbits only allows me to use 850mb 5 day averages, but the premise remains.

The strength lies in the West and “bleeds” east ladies and gentlemen, just like the BSR showed!

Here is what the EAR maps showed also, which is part of our “trifecta” of Organic Forecasting.

As you can see from above, strong system from the West comes into the Rockies and ejects into the Great Lakes which brings the cold air behind it.

For good measure, let’s add the SOID metric that we are researching as we speak…

Hmmm…a 33.15 drop in 3 days between November 13th and November 16th.  Coincidence…I think not.

Sad part is I was portrayed by a twitter account out east that I was denying the pattern change was even going to take place and “was wasting your time”.

Umm…yeah…Looks like my research and data was denying that.  He was just upset that I noticed he was calling for a ridge in the EPO/AO region when in reality, it was the WPO region.  Some education of the loading differences for EPO/WPO…
