Merry March 16th!   Do something to warm somebody's heart today. Don't just think about it........do it. Then think about it.............and how you just made somebody's world a tiny bit better. 


Our local chess tournament last Saturday got some great coverage. I'm extraordinarily proud of the kids and also the adults that helped run this event:

Currently, there is 0%  of the Cornbelt/Midwest with drought. There is no place even slightly dry there or east of the Rockies, other than in TX and coastal SC. 

I am pretty sure that this has never happened since records have been kept.

And we are being told that climate change is increasing drought.

The top map is the Canadian ensemble average, the maps below are the individual members that make up the average

+++++++++++++++++++++++++++++++++++++++++

Each member is like the parent, Canadian model operational model.......with a slight tweek/variation in parameters. Since we know the equations to represent the physics of the atmosphere in the models are not perfect, its useful to vary some of the equations that are uncertain(can make a difference) to see if it effects the outcome and how.

The average of all these variations(ensembles) often yields a better tool for forecasting. It's always more consistent. The individual operational model, like each individual ensemble member can vary greatly from run to run.........and represent an extreme end of the spectrum at times. The ensemble average of all the members, because it averages the extremes.............from opposite ends of the spectrum.........changes much less from run to run.

End of week 2....................12z ensembles from SATURDAY:
Analysis starting from a week ago, ending with today:


Last

Friday: The ridge west/trough east(downstream) couplet that was least apparent on the Canadian models shows up better today in Canada, which is where its capable of generating cold air.  However, this is offset by several solutions with an undercutting, milder flow. Today's overnight solution is a bit colder than yesterday's.

Sunday:  Much milder, west to east,  Pacific flow has overwhelmed and is undercutting any northern stream influence. The ridge/west, trough east couplet is barely seen on a small minority. 

Monday: Same much milder, west to east, Pacific flow as yesterday. 

Tuesday: Similar to the last 2 days. Very mild mean. 

Wednesday: The much milder, new pattern featuring mild Pacific flow that spreads from west to east across the country keeps looking impressive.

Thursday: No changes........very mild using updated 12z model run.

Friday: Still very mild but the southern stream(El Nino?) looks like its going to become more active and turn wet again after a week+ of dry weather.  Upper level trough seen from the Southwest to S.Plains area.

Saturday: Less uniform solutions with more uncertainty with regards to temperatures and precip. Most solutions have a very amplified upper level low/trough, mostly from southern stream origins with the tropical Pacific/El Nino in a state to provide contributions. However, the northern stream and flow pattern in Canada is a bit more favorable to deliver some cold into that system.

0Z GFS Ensembles at 2 weeks:

Analysis,  starting with a week ago:


Last Friday: The 12z solution yesterday amplified the ridge west/trough east feature and this continued early last night on the 0z solutions seen below..........which is much colder than 24 hours ago. The solutions below are are dominated by the Northern Stream , some are very cold in the Midwest/East. However, the 06z run early this morning was not quite as cold.

Sunday:  The trough with any ridge/west, trough east northern stream influence is way up in Central to Northeast Canada, leaving the US in mild Pacific air.

Monday: Similar to yesterday.

Tuesday: Still very mild

Wenesday: Still very mild but with a couple of outliers that want to over amplify a northern stream low/trough and drive it into Southeast Canada from the ridge/west, trough/east couplet in the higher latitudes.

Thursday: Very mild. Pretty uniform agreement.

Friday: Similar to yesterday. Not quite as wet as the Canadian model but wetter than yesterday and turning wetter after the dry period leading up to this. El Nino southern stream could get pretty active.........aimed at S.Plains.

Saturday: Deep upper level trough on all solutions. Ridging in Canada and down stream troughing could provide the set up for some higher latitude cold to drop south.

Ensemble mean(average of all the individual solutions above)


Last Sunday: Weak ridging west and troughing in Eastern/Northeastern Canada(where cold will be, just north of Northeast US.

Monday: Far Western North American ridge anomaly is more impressive today, however the down stream trough is in Northeastern Canada as much of the US has positive anomolies, all the way to the East Coast................so the Pacific warmth will likely be widespread. 

Tuesday: Still very mild in the US with Pacific flow, with a ridge/west, trough/east couplet way up in Canada that will be much too far north to bring northern stream flow or cold this far south..........but something to watch.

Wednesday: The big upper level ridge in Western North America builds all the way north........to Siberia but the downstream trough is waaaay to far north for any northern stream derived dynamics to get as far south as the US. This may just represent a seasonal migration northward of the jet stream and position of the main weather features. Mild Pacific flow dominates here. 

Thursday: Ridge west also extends farther east with positive upper level height anomalies into the Plains and eastward.  Very mild Pacific air spreads across the country.

Friday: Similar to Thursday.

Saturday: The upper level ridge anomaly centered by Alaska will have to be watched to see if enough northern stream energy digs southeast to couple with any troughing much farther east.

Latest, updated graph/forecast for AO and NAO here, including an explanation of how to interpret them. 

Previous analysis, with the latest day at the bottom for late week 2 period.


Last Monday: AO drops faster in week 2, now with numerous solutions solidly negative..........increasing chances for cold in the high latitudes to be transported towards the mid latitudes during the 2nd part of March. However, the very wide spread indicated uncertainty/low confidence. NAO has increasing spread and uncertainty on both sides of zero. PNA too but the trend for the PNA is up and most solutions are now positive at the end of 2 weeks vs previously around zero. This has also elevated the chances for cold to penetrate south vs the last few days using these indices.

Tuesday: AO continues to look more favorable for cold to move from high latitudes to mid latitudes in late March. Going from positive in week 1 and plunging in week 2, to negative by the end. NAO around zero. PNA increasing to positive which enhances the chance of cold penetrating into the US, east of the Rockies. 

Wednesday:  AO only drops to zero now at the end of week 2..............less favorable for frigid air to travel from high to mid latitudes. NAO stays a bit positive............also less favorable for cold. PNA is a bit positive, which still favors cold. None of the indices are very powerful forecast tools right today.

Thursday: AO which is positive, drops but only close to zero. NAO stays a bit positive, PNA also positive.........favorable for a ridge and warmth in the West. Other than that, nothing profound.

Friday: AO goes from positive to near zero. NAO is a tad positive. PNA is enough positive to favor a ridge West.

Sunday: AO stays positive, NAO positive...........NOT favorable for cold to travel from high to mid latitudes. PNA is positive, favorable for warmth/ridging in the West.

Monday: AO positive, NAO positive..........unfavorable to cold to move southward into the US from higher latitudes. PNA does get solidly positive because of the ridging in the West.

Tuesday: Indices today are becoming volatile at the end of week 2. AO positive but drops to near zero at the end of 2 weeks. NAO also falling but still a bit positive. The wide spread means a bit more uncertainty and a slight increase that cold could return at the end of March(but still unlikely). PNA positive but falling. It's getting too late in the heating season for cold to make a big difference.

Wednesday: Positive AO and NAO make cold air intrusions unlikely. Positive PNA means ridging and warmth in the West.

Thursday: Positive AO and NAO still make very cold air intrusions unlikely. Positive PNA because of the ridge in the West..........which expands eastward.

Friday: Positive AO and NAO. Positive PNA is dropping fast late in week 2 as the upper level ridge in the Soutwest breaks down from an El Nino induced Pacific stream?  Mainly to the south.

Saturday: Some noteworthy changes today for the first time in a long while. Both the AO and NAO are not as positive and drop fast towards the end of week 2, with several members actually in negative territory then. Unlike previous days that made very cold air intrusions very unlikely with the indices at those values, today, the door is open for that POSSIBILITY...........just need to be watched. PNA stays positive, a sign of the upper level ridging in the Northwest US to all of W. Canada. Upper level troughing and Tropical Pacific moisture/energy will be a factor farther south.

Another horse dies at Santa Anita, one day after the main track reopens   ....

March 14, 2019 10:49 A.M.

https://www.sandiegouniontribune.com/news/california/114443340-132.html



Santa Anita Park suffered a 22nd horse fatality since Dec. 22 on Thursday morning just one day after the main track was reopened for training. The horse suffered a severe injury and was euthanized. A track spokesman said a “major corporate announcement” is expected before noon.

Princess Lili B broke both front legs at the conclusion of a half-mile workout, as first reported by Brad Free of the Daily Racing Form and confirmed by The Times. Training will continue on the track, Free reported.

It was only the second day of training on the main track after Santa Anita suspended racing last week in response to the previous deaths.

No definitive reason for the rash of horse fatalities has been identified. After repeated inspections and dirt sampling, the rehiring of track consultant Dennis Moore and enhanced safety protocols, Santa Anita has been trying to move toward a resumption of racing on March 22.

In all, 196 horses safely worked out at the track on Wednesday, according to a Santa Anita spokesman — 112 on the main track and 84 on the training track, a softer course where there has yet to be a fatal injury during the winter/spring meet.

Changes instituted by Santa Anita in response to the deaths included a requirement that trainers give 24-hour notice on workout requests so that veterinarians can review horses in advance and spot possible concerns.

Santa Anita continued to conduct training workouts after the injury Thursday. The track is expected to announce additional safety protocols to horsemen this afternoon.

The injuries, though, have many long-time horsemen voicing concerns.

“It’s mind-boggling to me,” said trainer Art Sherman, who trained Kentucky Derby winner California Chrome. “I’ve never seen this as long as I’ve been around. In horse racing, you’re always going to have accidents. I don’t know what to make of it. I’m at Los Alamitos, and we haven’t had any problem at all. It’s scary seeing all these breakdowns.”
