April 27 2002: Heavy snow falls over the Twin Cities and central Minnesota. Chanhassen receives 6 inches, and vivid lightning is seen with the snow during the evening. 1996: Embarrass records a low of 9 degrees. Some central, and most northern, Minnesota lakes are still ice-covered. 1921: A late season blizzard hits Hibbing. The temperature was 75 degrees three days earlier. For Monday, April 27, 2026 1899 - A tornado struck Kirksville, MO, killing 34 persons and destroying 300 buildings. (David Ludlum) 1931 - The temperature at Pahala, located on the main island of Hawaii, soared to 100 degrees to establish a state record. (The Weather Channel) 1942 - A destructive tornado swept across Rogers County and Mayes County in Oklahoma. The tornado struck the town of Pryor killing 52 persons and causing two million dollars damage. (David Ludlum) 1987 - Forty-two cities in the western and south central U.S. reported record high temperatures for the date. The afternoon high of 87 degrees at Olympia WA was an April record, and highs of 92 degrees at Boise ID, 95 degrees at Monroe LA, and 96 degrees at Sacramento CA tied April records. (The National Weather Summary) More than 300 daily temperature records fell by the wayside during a two week long heat wave across thirty-four states in the southern and western U.S. Thirteen cities established records for the month of April. (Sandra and TI Richard Sanders - 1987) 1988 - Mount Washington NH reported seven feet of snow in ten days, pushing their snowfall total for the month past the previous record of 89.3 inches set in 1975. (The National Weather Summary) 1989 - Thunderstorms produced severe weather from the Lower and Middle Mississippi Valley to Virginia and the Carolinas. Hail up to four and a half inches in diameter caused five million dollars damage around Omaha NE. Thunderstorms spawned eleven tornadoes, and there were 160 other reports of large hail and damaging winds. (The National Weather Summary) (Storm Data) 1990 - Thunderstorms produced severe weather in eastern Texas and the Lower Mississippi Valley. Severe thunderstorms spawned thirteen tornadoes in Texas and twelve in Louisiana. A tornado southwest of Coolidge TX injured eight persons and caused more than five million dollars damage. There were also eighty-five reports of large hail and damaging winds, with baseball size hail reported at Mexia TX and Shreveport LA. (The National Weather Summary) (Storm Data) Forty-three cities in the eastern U.S. reported record high temperatures for the date. Records highs included 94 degrees at Charleston WV, 95 degrees at Baltimore MD and96 degrees at Richmond VA. (The National Weather Summary) 2011 - An estimated 305 tornados between the 27th and 28th sets a record for the largest outbreak ever recorded, including two EF-5s, four EF-4s and 21 EF-3s. Arkansas through Mississippi, Alabama, Georgia, southern Tennessee, Virginia to Pennsylvania and New York were all affected. An estimated 300 died including 210 in Alabama alone. This brought the April total past 600, the most in any month in recorded US weather history.

Slight risk today has been stretched SW into NE Texas. Last few runs of the HRRR is showing some storms late this afternoon/evening forming near Dallas and points east. There's also potential for isolated storms south/west. Hail/wind is probably the biggest threat, with isolated tornadoes still a possibility. Tomorrow will have another threat for severe weather with storms potentially initiating near Sherman and headed south/east from there.

Well, since the 90 degree day a week and a half ago.

Rainy, chilly morning with temps in the upper 30's. Flood watch out for NE MN.

My ornamental grasses starting growing in the heat of two weeks ago only to be shocked by the hard freeze last week. As a result it all looks like shit currently. The lawn is coming along decently though.

The most exciting part of this event up here might be the wake low behind the rain this afternoon.

Nice to see the ground not completely dried out for once. Been awhile. Now if we can string together a few 70 and sunny days maybe itll feel like a real spring lol

Are you all leaf out all trees?

OHC peaks - strong/super el ninos 1982-83: 2.07 (October) 1986-88: 1.22 (January 1987) 1991-92: 1.98 (February) 1997-98: 2.56 (October) 2009-10: 1.75 (November) 2015-16: 1.97 (August) 2023-24: 1.45 (November)

shame about missing the bangers, glad for more consolation prize rain

If there's more sun than cloud in late April, the max will probably be AN at least 90% of the time. Last 2 days' max here averaged 61, which is 4° AN. The minima averaged 26, or 6° BN. The sun is mid-August strong.

The latest BoA relative was just released. As expected, it cooled way down from the April Nino 3.4 prog of +0.6 as it is now a much more realistic -0.2 (that actually will likely end up slightly too cool as I expect it verify -0.1 to 0.0). However, despite that marked cooling of April, it warmed for its Sept prog from ~+2.35 to +2.6. Also, this is the first run with Oct, which it has at ~+2.85. On the one hand, one should keep in mind how much it overdid ONI in 2023. OTOH, this latest has RONI near the level it had ONI in 2023. So, although we should be aware of a quite possible warm bias at play here thus causing the RONI prog to be overstated, we should also be aware that it is currently implicitly progging ~0.5C warmer RONI vs 2023. Keep in mind that RONI peaked at only ~+1.5 in 2023-4. We’re very likely headed to a significantly warmer RONI peak in 2026-7: BoA RONI prog from 2 weeks ago: a ridiculous +0.6 April and a +2.35 Sept: Today’s BoA RONI prog: much more realistic cooler -0.2 April but Sept a warmer +2.6; first run with Oct (+2.85):

Got 0.12" in ATL metro Saturday. FFC mentions multiple rounds of rain coming this week but also said models may be underrepresenting dry conditions and most won't see much more than an inch.

Hmm - this implies annual oscillation of the Earth's temperature, does it not? I didn't think that was a thing. I know there are oscillations, but they tend to be correlated with ENSO cycles and such, do they not? IOW - seems to me this is just a subset of global mean temperature - e.g. the northern hemisphere only, is it not?

Nah. Old chasing friend of mine was trying to talk me into going with him last night. We've been talking about this setup, the potential mess it could be most of the weekend. That's the area, IMO, I'd be IF I were chasing. I decided not to go. He left last night is in a hotel just S of Springfield. I'll be playing base camp for him lol. Do believe for any lone sups its gonna be highest chance in that area. Could be a lot of embedded sups and MCV spin ups but chasing those just sux. Think kind of like the last system, Tail End Charlies will be best isolated sup options when you get bows and shrimps like this setup could be full of. Like you said that area just got elevated to MOD so yeah, thats a good call IMO if your going. Anything isolated East into IL/IN is probably going to be close to or after dark. Another reason I'm not going. Good chance for a late night MCS/MCV rolling through here. I've got a donkey, 2 goats and 2 dogs. They get quite upset when there's big thunder dragons outside lol. Good luck to anyone who dares and be safe. Idiots IPhones and storms don't mix lol.

Mother's day was always the hope. Looks like some are still trying to put lipstick on the pig, even though the models have been consistent about this for about 2 weeks now.

You need to suffer another 15 years of it and then you'll be as iron-hulled to it as the ships Labrador never claimed. You'll limp into port every spring surviving by the notion that 70 in May is actually a motherfucking bargain and you'll be happy. ha! If it is 70 and with more sun than cloud days ...? Shiiiii I'm calling that a relative win and a day. But yeah.. looks like in 2 weeks when the April/NASA numbers are out, the graph will again register that whether we are above normal for April or not, we will in comparison to everywhere else, be below ... every where else. Since October, 2025 we've be winning that distinction, save for one or two weak argument months. Altho... heh at any time NASA may cease to exist because of the creepy "operation silence the consilience" going on.

Today is a stunner though. Went into work late so I could sit in the sun with my coffee and listen to the birds.

61 / 48 off a low of 35. Nicest day of the week coming up. Not bad Tuesday but clouds build in ahead of the next batch of rain on Wed/Thu. Continued cool and possibly wet one or the whole weekend. Moderation betwen May 5 - 9th and next shot at 70s or warmer then but it may take till mid month to push heights / riding east for any persistent tineframe.

Losing May is like losing December in the winter.

Hopefully things shift by mid May.

Pattern blows. Getting 70 in may is meh. Constant troughing with shit settling in later this week.

The relative weeklies centered on last week were released this morning. They as expected based on following the dailies show a slowdown in the rate of warming in 3.4 and 3 (from 0.4 the prior week to 0.1 last week). Also, note that Nino 4 cooled 0.1. Nino 1+2, which is more volatile since it covers a much smaller area, cooled 0.3. I expect that this cooling there is just a blip that will reverse soon: Date………………...1+2………3………3.4……..4 08APR2026 1.1 -0.2 -0.3 0.2 15APR2026 1.2 0.2 0.1 0.6 22APR2026 0.9 0.3 0.2 0.5 https://www.cpc.ncep.noaa.gov/data/indices/rel_wksst9120.txt

Not a great or warm AN pattern by any means but as long as sun comes out it’s warm inland

yep acatt way overblown with those death sentence calls and charts last week
