2018 Spring/Summer Outlook


Tom

Recommended Posts

As we enter the final stretch of met Winter, who's ready for Spring???  I'm sure there are a few on here itching for spring time thunderstorms, warm sunny days...but will this year be a fast start to Spring or delayed???  The latest data coming in is suggesting a slow start to Spring the farther west you are in our sub forum.  Polar Blocking and the PV Split is conducive for a delayed start to Spring which may delay the chances for severe weather depending on how much influence the blocking will have on the storm track in March.

Let's dive in and discuss....

 

 

Here is the latest temp/precip outlooks from the CFSv2...

I really like the wet look out in the Plains and 4 corners which would certainly be a site for sore eyes for those out there who have been very dry this winter.  Just like last year, I believe the blocking and the slowing of the jet stream will allow for storm systems to slow down and deliver moisture where they need it most.

FWIW, most analogs suggest that after a cool/wet Spring, Summer turns hot and dry which is something most climate models are showing for Summer.  For instance, the JAMSTEC has a widespread hot/dry summer...

It sucks but I'm probably going to be moving on to this thread over the next few weeks. With the exception of one last holdout for a significant March cold wave, I'm moving on to spring. My early takes on spring, long and turbulent storm season and long hot miserable summer over the center of the country. It sucks but I'm going to check my mower out here in a week too. It seems like that thing has had 3 10+ month long growing seasons in a row. I just hate that I agree with the models to a T. Makes me want to leave Oklahoma til November. Lol.

I really feel for ya OKwx!  Back in the Fall, the pattern looked pretty awesome across your area but that pesky ridge kept popping in the southern plains and east.  I sure hope you score the moisture over the next couple months so that the drought conditions don't come on quickly in the Spring.  Severe wx threat is probably going to be big down in the southern plains as I'm seeing a pretty wild clash of air masses next month into April.  The LRC pattern suggests this is probably on the table as we move along.

 

Besides that, how have you been?

I've been doing ok. I think a combination of working second shift hours and this snowlessness for the last 3 years is just taking it's toll a bit worse than usual this year. Always in the wrong place at the wrong times I guess. Story of my life. :lol:

Streaks are meant to be broken and we certainly hope that your streak will be broken soon!  Hey, the Cub's did it a couple years ago so I'd imagine your next bud!  

 

Meantime, here is the latest IRI Spring and Summer outlooks....

I'll get a winter back here one day.

 

Looks like a summer heat dome pattern. That's about what I'd expect out of the core of this summer.

I'm starting to see trends that are rather similar to what happened last Spring when all of a sudden it turned real wet and cool across the south/central Plains and of course into the MW.  The CFSv2 has been showing this trend and it's a really good thing for those that are experiencing drought conditions.  It's always better to have wetter soils as you creep closer to Summer to mitigate any severe droughts or excessive heat waves.

Furthermore, I would take another repeat summer like we did last year as these maps look ideal to me...pockets of warmth and wet signals are common in the summer so I wouldn't take this verbatim.  Trends have been cooler also for summer across the central CONUS.  I'm expecting to see a lot of frontal boundaries and as we get deeper into summer the "ring of fire" pattern might be really active this year.

Dry trends continue to show up across the ag belt region of the central Plains next month if you are to believe the CFSv2.  Not looking good for NE/KS posters.  My gut tells me you guys out west will be complaining from the heat and dry weather late Spring into summer.  Unless things change soon, I'm not convinced that a wetter pattern sets up like it did later in Spring last year.

You know it's bad when Tom is pessimistic.

 

Not a good way to start the week. I’ve had my fears that this pattern was coming. Would not be good for agricultural interests for sure.

Ya guys, thus far this pattern early on in March is not delivering the much needed precip even with all the blocking that is in place.  My fear is the SW ridge, which has been a common theme in this year's LRC, will show its ugly face early and often this Spring.  It's going to be a hot and dry summer near the TX Panhandle and that's not a good thing for your neck of the woods.  I'm sure there will be bouts of precip here and there but I believe the soaking rains will end up being farther east into the MW/GL's/OV.  Let's see if these trends are going to continue.

You’re right Tom. Most times in this pattern we have huge March storms that deliver a wide variety and plenty of precipitation including blizzards. We are fortunate around here that we sit on top of the Ogallala Aquifer so irrigation is the lifeblood of this region but it is expensive. I come from a farming background, my father In law and brother in law farm 2500 acres of corn and soybeans along with raising several hundred head of cattle. They tell me the coffee shop talk of a hot dry summer is real and they are concerned. Unfortunately, we all pay for it in higher grocery bills down the road.

Unfortunately, I think the “Garden of Eden” ride your area has had over the last couple years will end this growing season. I hope I’m wrong.

Sadly, I'm in agreement with you all. Somewhere in our subforum is in for a tough summer. I thought I was the most likely candidate at one time but now appears that threat is looking more likely to my north and west. My ground is fully saturated for the first time in over 8 months.

Spring around the corner. Looking forward w the time going one hr ahead this Sunday as well.  Barbeques will get going soon as well. Spring cleaning will be underway also and boy, do I have some Spring cleaning to do in my house. I believe by April, some nice weather will arrive. Knowing SEMI has a snow magnet this Winter, who knows. We will see. If we end up getting a snowstorm in April, then, I will get pissed.

So far, April is looking a little better than March, although, still a bit nippy.

If there was a mod/strong El Nino present or forecast to build, then I'd agree to the overall warmth across the globe.  However, just look back to the pre-winter ideas all the dynamic models suggested and they obviously did NOT see the Eurasian cold and North American cold.  You can refer to Dr. Cohen's blog https://www.aer.com/science-research/climate-weather/arctic-oscillation/

In the midst of the "Spring Barrier" season, there is an obvious battle among the various dynamic models where we may be heading in terms of the ENSO pattern across the equatorial PAC.  Like last year, the CFSv2 is indeed holding steadfast on the idea that waters remain cooler than normal throughout the Spring/Summer months and hold onto the idea of a weak La Nina.  Not surprisingly, like last year, the Euro wants to bring on a weak Nino by the end of Summer.  I don't have any faith in the Euro as it has not shown any confidence in predicting ENSO events.  IMO, the CFSv2 has been much better in terms of forecasting the ENSO SST pattern compared to any of the global models.  The JAMSTEC comes out next week and I'm curious if it sticks to ENSO neutral conditions throughout the summer months and into next Fall.  Last year, both the JAMSTEC/EURO were predicting a moderate Nino by summer which was a big FAIL.

 

Here is the latest CFSv2 trends...

Yuck, the latest JMA monthlies advertising a stout -NAO in April and its looking similar to the latest trends of the CFSv2 for a cool to cold April.  Similar look continues into May, but interestingly, June turns hot which is rather similar to what happened last year.

I find it rather interesting to see the CFSv2 is actually holding onto the idea of a weak La Nina throughout the summer months.  Not only that, but like last year, it is predicting a cooler summer over the Arctic regions and signs of a weak vortex across the Archipelago regions in Aug/Sept.  If this is to happen, the idea of less arctic ice melt this summer season would provide some evidence that we are in fact turning the corner in terms of ice growth.

Colorful, but am I the only one who feels that perhaps they got the color scheme reversed? Logically speaking, you'd have the blue shades on the wettest end of the scale, and reds/pinks/browns for less moist and/or dry conditions. Maybe I'm just too logical

The JAMSTEC's latest run seems to be the most consistent global model suggesting ENSO neutral conditions to persist through the entire year.  IMO, like last year, models were to bullish on predicting a possible El Nino.

Unfortunately, that looks like it could verify.  Not much worse than hot and dry.  Around here with all of the irrigation, center pivots, and corn putting water back into the sky, it just adds to the humidity (dew point), and can make it unbearable at times.  Detasseling corn in my youth might have been one of the hardest jobs I've ever had.  Being in the middle of a tall corn field with no breeze and stifling humidity made up my mind very quickly that I needed to get a college degree.  When I see people working out in the elements, farming, construction, roads, etc. I am very appreciative of the work they do.

Ditto to the Bolded!  I will add that there is support that it might not get as bad in NE as it could get.  We really need to see good moisture April-May to see how things progress into Summer.

 

On another note, something quite odd transpired on the latest CPC equatorial sub surface anomalies on the very last frame between 160-180W...it's like a knife of cold waters split up the warm pools below...
