Per FFC for Atlanta for April 4th: FRIDAY MOSTLY SUNNY. HIGHS AROUND 90. If this verifies at KATL, it would be the earliest in the season 90 on record by a whopping 19 days!

Here are the coldest of today’s 12Z GFS and Euro for the upper SE overall: both are during the morning of April 9th: GFS: Euro:

1. Thanks for posting this! That’s noteworthy news for sure. So, 3/31/25 is the first day the WCS daily was positive since way back in late Oct of 2022 at the very least (as far back as I can look per my files). It’s possible that the last WCS daily positive was in August of 2021, but I have no way to know. This is the furthest back map I have: 2. But don’t forget that whereas it is a +PDO per this WCS map, NOAA runs significantly lower and thus is still -PDO.

Unfortunately my area had severe wx yesterday ~6PM when the line came through despite no actual severe thunderstorm warning (though there was a SWS for strong thunderstorms as I posted as well as nearby warnings): 0547 PM TSTM WND DMG 1 NW MEINHARD 32.19N 81.22W 03/31/2025 CHATHAM GA EMERGENCY MNGR TREE DOWN AT BENTON BLVD AND STATE HWY 30.

Are you aware there was a severe wx thread for this? I posted on it for my area:
-
Further update: There continues to be no indication of a “killing freeze” outside of the mountains. “Killing freeze” is the wording you had first used and is what I was responding to. You had said: “Yay a killing freeze...”

The forecasting problem with CANSIPS is that its runs had been predicting a Modoki El Niño emerging by late summer back in runs going back to late last summer. But the model has since been gradually delaying more and more with each subsequent run the C equatorial Pacific warming, which tells me it is lost: 8/31/24 Cansips for August of 2025 had suggested Modoki El Niño already starting: But new CANSIPS for same month has backed off considerably and now delays Nino by 6 months til way out in Feb of 2026: Thus I’d take CANSIPS maps for winter 2025-6 with a huge grain just like would normally be the case when looking so far ahead on a seasonal forecasting model, which y’all normally would do: @Stormchaserchuck1 @40/70 Benchmark

That’s always great news to me.

The effect of SSWs down here (which in the current case will end up as a final warming similar to that of 2016 in that the reversal looks to remain through the warm season) often start with warmth followed by BN temps. The upcoming week will be an absolute torch before the cooldown. 0Z GEFS NAO forecast:
-
There’s been and continues to be no indication of a killing freeze (outside of the mountains, of course). Also, the last few GFS runs haven’t been as chilly. But I’m still looking forward to a reprieve from this week’s heat.
-
It’s now in the low 80s here with PC skies. Any potential severe thunderstorms here would be in the early evening most likely.
-
The latest GFS (6Z) isn’t as cold in the second week of April.
-
Do y’all realize that RDU has had measurable snow twice after April 9th? They got 0.3” on 4/11/1989 and 1.8” on 4/18/1983!
-
I’d admittedly enjoy a nice cooldown that week, especially since it would be following a four week long mild period. Also, I’m a chilly wx fan in general. Even if folks don’t want it, I feel it’s important to discuss the potential and not be caught off-guard.
-
If this cold verifies, which is growing in likelihood, I will forever remember this as the Tony @dsaurcold wave since he’s been warning us about this potential around Masters time:
-
Barney is even threatening to make an appearance….in April! No, you’re not seeing things. 12Z Goofy for 8PM on April 8th:
-
12Z GEFS still has some although not the operational outside of the mtns. Op gfs is still cold during this period, regardless:
-
Even though it is also on the 6Z Goofy, I realize that with this being out 9 days that this is so highly unlikely based on climo:
-
Tony, Get a load of the 0Z Goofy! Holy cow, I think Goofy had a little …no, a lot…too much: And snow on April 8th, Tue of Masters Week! Is this real? Is this because of the current very strong stratospheric reversal?
-
The chill is intensifying for Masters week
-
And now today’s Euro Weeklies for 4/7-13 have cooled a lot due to a stronger -NAO…chilly Masters may be ahead: Yesterday’s run: Today’s run:
-
As a result of this strengthening -NAO, today’s Euro Weeklies have cooled a lot just since yesterday’s run for 4/7-13 (Masters Week): Yesterday’s run for 4/7-13 Today run for 4/7-13
-
Is there going to be a chilly snap during the upcoming Masters just as has occurred in some past Masters? Be ready to break out the coats one last time then just in case? @dsauror others have an opinion?

I just watched the Thursday daily Joe Bastardi video (he’s now at Weather Bell for those who don’t know). Even he, who himself has hyped at times in the past, said that this Daily Mail headline was hype to get extra clicks. He thinks Accuweather should respond with a complaint that this is not what they forecasted, which was a range of 3-6 TSs or stronger. That’s far from forecasting 6 Hs smashing the US! When even JB is complaining about hype…. @cleetussnow
