Spring 2026 Pattern Discussion Thread


 Share

Recommended Posts

I hope you enjoyed the Skywarn talk! I'm down in Chatty so I was not there. However, I attended an NWS emergency manager talk in Chatty on Monday that covers the new SPC products. 

As for the rest of March seems like we might get into a couple cooler weeks starting mid-month. That's more valid East or upper half of the Tennessee Valley. Mid-South could remain warmer. Such a pattern leaves the door open for Mountain snow showers. First we have to get through the mid-term blowtorch.

I don't see a reason to forecast a cool depressing spring though. Some back and forth like Carvers mentions seems reasonable. Warm weeks, I'd like to add side orders of southwest flow aloft and CAPE.

You got it! I think of the Mid-South starting with the MEM CWA, then add West Kentucky. Might some add to the halfway point of KY/TN. Sometimes for chasing I'll fudge it to northwest Alabama. Vague boundaries help hedge forecasts, to be honest haha.

Note that all of Mississippi and all of all of Alabama are considered Deep South too.

East Tennessee into northeast Alabama I'll often refer to as the Tennessee Valley. Of course the River goes on downstream curling north into the Ohio River, but at that point I'm talking Mid-South.

Speaking of all this.. Mid-month cold could start Mid-South. However it should eventually have a little longer stay in the Valley. Keep in mind cold in March is nothing like cold in Feb. Shouldn't be too bad. At the same time, Mountains could get late season snow showers a couple times.

The 6z GFS was interesting for Thursday.  Both the 0z GEM and 0z Euro are still showing 1-2 amplification events incoming around mid-month and just after.  This could be a WILD swing given the temps we have seen during the past few days.  Highs could be 40-45 degrees colder at TRI than what we are seeing and will see this weekend.  Wind chills in the mid-upper teens would not surprise me at some point between d5-16.

Man, these are some cold operational runs.  To be clear so there isn't confusion.  The cold I am looking at begins around mid-month, say roughly around 200 hours. 12z models are quite cold w/ snow chances embedded - both the 12z GEM and GFS.  I don't see any big storms(potential is probably embedded within ensembles as Knox has shown), but snow could be in the air on more than one occasion.  The second half of March is not looking warm IMHO.  Again, this looks like a continuation of the pattern.....cold -> record or near record warmth -> small cold shot -> more warmth -> big cold shot.  We have cycled through that pattern already twice.  I think the chances of that occurring a third time are increasing, but w/ a Spring twist.

52 & 49 next Monday & Tuesday going to hurt.  Thankful it appears to be a quick shot that does not last long.  Guess it’s time for the folk lore winters.  Is it locust up first? 

There's a pretty good chance you see colder reading's than that as some very cold air lurks to our North in Canada.

I think around here anyway , the first is called something like Sarvis.?. After a type of Tree I think. Second, redbud, third Dogwood then Blackberry.

Nothing to tat really of course. I've witnessed years with more than that many cold snaps and some less. The Dogwood one "may" have some merit; if you tie in a Spiritual Component.
