Pattern April Thread

Please enlighten us on how GW has changed spring.

I think it has to do with the much slower jet-stream causing a more amped pattern due to Arctic amplification which is all from AGW. This is happening in the summer too with these "cool" shots in July and snatching up canes pulling them up into the NE.

Flooding is more common too as systems tend to move slower and there is more water vapor in the atmosphere.

Nope but it's interesting to see some folks finally excepting reality as it's right in your face at this point.

I thought we where supose to call it climate change now instead of GW? That way it applies to fire, drought,flood, BN cold, illegal immigration etc
 
Picked up 1.68” of rain today! ☃️?

I know this isn't the place for the whole global warming debate but that obviously has played a major role in our weather that kinda is making up the new norm vs what we have always been used to. It will be interesting to see if these delayed spring and prolong "winter" type patterns are now just the new norm or are we just in a typical 5-10 year funk. I am not for all the frost and freezes because of the agriculture issues, but below normal through spring at least for the highs is nice. I prefer to keep 60's and low dews around for as long as possible for the inevitable 5 months of hell on earth starts.

The new 30-yer averages do give credence to the feeling that the start/end of seasons has shifted forward about 1 month, with April trending cooler and October trending warmer.
 
Models have been showing another decent temperature gradient tomorrow, with low 80s for DFW and mid 50s for Wichita Falls during peak heating.

With the +PNA / -NAO / -AO, that may trend cooler as we get closer in.

What happens to the MJO will be key. If it goes into Phase 6 (which is what the GFS thinks will happen), then all bets are off for a warm pattern.

While a +PNA can still cool us off (and probably still will), wavelengths are much much shorter this time of the year vs winter, a +PNA with a block on top probably favors a cutoff, especially with the deep vortex hanging around Alaska, but if the pacific jet retracts any, we are probably gonna get a very cool longwave trough, the icon solution makes sense because with those wedge boundary setups when they back off, it normally gets really warm for a couple of days

You can have all the 80s and 90s you want! I can’t take that heat anymore! #IOWALIFE?

Planting season facing big delays given the weather this spring and the coming 2-3 weeks up there . Any planting after May 10 yields a diminished yield of 1.5 tons per week for crops such as sugar beets . ….

Yeah, everything is 4-5 weeks behind where we were last year up here! It hit 80 the first week of April and we never had another freezing or below temp until October! This spring has been ridiculously cool/cold! And looks to continue the next 2 weeks and beyond possibly! They tell you to not plant annuals up here until after Mother’s Day, guess I’m hard headed
