ENERGY   


The WxRisk Energy Page is a new product that I recently have started since WxRisk is doing so much ENERGY business  these days. This PAGE IS A SAMPLE PAGE.   To reach the WXRISK DAILY ENERGY/...  you will have to email me  at energy@wxrisk.com  and ask for site access.  

At the Bottom of the page is the Rgional Map  of the North American Electric Reliability Council.  It shows the 10 area   regional breakdown of the Power Grid across North America.

The 8 day Temperature forecasts are based on a variety of sources and is far superior to anything similar product out there. Most temperature forecasts, which  as so important to large and small Utilities, Traders, Brokers and Planners, are based either exclusively on the MRF -MOS product (which is a wretched and nearly useless temperature product) or the new and improved MAV.   

WxRisk Temperature forecast also temperatures derived from the ECMWF Model (wxrisk may be the only source in America that uses the ECMWF model  is this manner),  as well extrapolated Korean Model and the MRF ensemble mean Temp forecast. This product is updated by 8 AM   Monday through Friday  and Sunday evening.

WEATHER HEADLINES....   APRIL 4   2001  issue
 

  • OPMRF DEVELOPS +PNA PATTERN DAY 9-10   WANTS TO BRING BACK WINTER....  NOT!!

  • MEAN TROUGH TO REMAIN  OVER WESTERN US THROUGH APRIL 15....

  • SOUTHERN PLAINS ...LOWER MISSISSIPPI VALLEY AND SOUTHEAST US TO STAY MUCH ABOVE NORMAL THRU APRIL 10 PERHAPS LONGER

  • POSSIBLE INTENSE WESTERN PLAINS LOW  APRIL 6 -8   MAY BE SIGNIFICANT SEVERE WEATHER PRODUCER.

  • STORM TRACK TO BRING EXCESSIVE RAINFALL NORTH OF I-70  ...ACROSS THE OHIO VALLEY ... AND PERHAPS INTO THE NORTHEAST US  THROUGH APRIL  14

MODEL INSIGHT  -- FOR METEOROLOGISTS

The April 4 OPMRF is useless  beyond Day 7. 100% bogus. If you use it   you will get burned.

How do I know this?  For one the OPMRF has a known bias of overdoing the phasing of the streams and overwhelming the eastern US with cold air.  It is the primary reason why the OPMRF does so badly with East coast Lows and Noreasters--- that model is almost always forcing Low off the SE coast of the US and out to seas and rarely catches on until 4 -5 days before the event --if then. In this particular case  the OPMRF develops a deep 500 low in the Gulf of Alaska  Day 8 thru Day 10 which drives the ridge into western Canada  where a split flow  +PNA pattern develops and cold air-- indeed arctic cold pours southward.  

Second there is NO support for this scenario at all.  NONE 17 Canadian models offer this solution and only 2 of the 12 MRF ensembles have the big trough in the eastern US idea nor  does the Day 10 Ecmwf  support the Big trough in the East idea in any way  shape for form.  Don't' use  the APRIL 4   OPMRF.!

BOTTOM LINE  Do not use the Operational MRF..it is an "outlier" when compared   with vast majority of the other MR (Medium range)  models.
OPMRF warning_.gif (236 bytes) DAY  8-10     too Dry
ECMWF check3.gif (144 bytes)
GGEM q_mark2.gif (992 bytes) Western Trough depicted too shallow
UKMET looks reasonbale
MRFX   still has western US trough too shallow
ETAXX      April  3 ETA - XX   did not run
NOGAPS looks much better  than the OPMRF
MM5 Not available today beyond  120 hrs

***    SAMPLE  ***

8  DAY TEMP     FORECAST TABLE  

MB= MUCH BELOW -5 or more Degrees Below Normal
B =  BELOW -2 to -5 Degrees below Normal
N= NORMAL +2Degrees Above to -2  Degrees Below Normal
A= ABOVE +2 to +5 Degrees Above Normal
MA = MUCH ABOVE +5 or More Degrees Above Normal

Some of the temperature forecast below have various levels of certainly or confidence in them. This is important especially in the colder months from November 1 to April 15  when the position of various weather features can cause a wide swing in temperatures within a small area.  To communicate this uncertainty WXRISK uses 3 levels.

RISKY NORMAL CONFIDENT

RISKY...   NORMAL   and  CONFIDENT. Thus a "B"  forecast (for Below Normal)  for a particular location   may have a Yellow Background in that cell if there is a good deal of model/data uncertainty--perhaps there is a front or large weather system near the location.
