(The Weather Channel) 1966 - The 1.6 inch snow at Chicago, IL, was their latest measurable snow of record. Previously the record was 3.7 inches on the 1st and 2nd of May set in 1940. (The Weather Channel) 1970 - A very powerful tornado struck the city of Lubbock, TX, killing 26 persons, injuring more than 500 others, and causing 135 million dollars damage. It was the most destructive tornado of record up until that time, and came on the 17th anniversary of the twister which struck Waco TX killing 114 persons. A second tornado killed two others persons in Lubbock, and the two tornadoes damaged or destroyed nearly a quarter of the city. (David Ludlum) (The Weather Channel) 1982: The second of three severe weather episodes occurred on this date through the 12th across parts of Oklahoma. On this date, severe thunderstorms produced 18 tornadoes across the western part of the state. One tornado touched down southeast of Altus and moved across Altus Air Force Base. In Altus, almost every roof in town was damaged by large hail. At the base, 70 buildings were damaged or destroyed, 30 airplanes were damaged, and 6,000 vehicles suffered hail or tornado damage. Overall, two people were killed, 60 others injured, and the total damage from this particular storm was more than $200 million dollars. (Ref. Wilson Wx. History) 1983: A late spring snowstorm hit the western third of South Dakota on this date through the 12th. Snow amounts ranged from 3 to 10 inches and in some areas the snow was accompanied by thunder, lightning, sleet, and hail making for an interesting mix of weather. The heaviest snow amounts fell in the northern Black Hills although some areas in the plains had strong winds creating drifts high enough to make roads impassable. (Ref. Wilson Wx. History) 1987 - Early morning thunderstorms produced up to four inches of rain in southern Texas, with flooding reported from Maverick County to Eagle Pass. Evening thunderstorms in northern Illinois produced golf ball size hail and wind gusts to 70 mph. (Storm Data) (The National Weather Summary) 1988 - Unseasonably warm weather prevailed in the southwestern U.S. Reno, NV, reported a record high of 89 degrees. (The National Weather Summary) 1989 - Afternoon and evening thunderstorms produced severe weather in the High Plains Region. Thunderstorm winds gusted to 71 mph at Gillette WY, and baseball size hail was reported at Pecos TX and Fort Stockton TX. Fort Stockton TX was deluged with 7.75 inches of rain in less than two hours. (The National Weather Summary) (Storm Data) 1990 - Unseasonably cold weather followed in the wake of a spring storm in the north central U.S. Seven cities reported record low temperatures for the date, including Madison WI with a reading of 29 degrees. Thunderstorms produced severe weather in Kansas, Oklahoma and the northern half of Texas. Severe thunderstorms spawned four tornadoes in Texas, and produced high winds which overturned four mobile homes northwest of Abilene TX injuring ten persons. (The National Weather Summary) (Storm Data) 2005 - Strong thunderstorms affected parts of the U.S. Great Plains. In the Hastings, Nebraska area, significant severe weather occurred, including very large hail, damaging winds and widespread flooding. Radar estimated rainfall accumulation locally exceeded 10 inches. 2005: Grand Island, NE set new 6, 12, and 24 hour rainfall records with 6.38 inches in 6 hours, 7.16 inches in 12 hours and 7.21 inches in 24 hours. Very heavy rain also fell in parts of northern Montana. Red Lodge and the surrounding foothills received 4.5 to 7 inches washing out some roads. (Ref. Wilson Wx. History)

Spring is coming, and some needed rains Board should liven up a bit with stm potential.

It's been 82 a small handful of early afternoons since early April... perhaps 3 with a smattering of 78s. The vast majority of time it has been less than 62. Not sure what the nocturnal biases have knocked out, but as Scott and I had noticed actually back in late March ( and still looks to be the case when cursory running down the numbers), we tend to be negative for 8 or so days back to back, then we get two 20+'s ...skewing the whole month positive. Figuratively speaking It's been a bullshit liar spring. Cold and shitty, despite sun at times and fleeting bombastic warm days. The small handful of 80 days we've seen thus far also had DPs less than 50... They were rad bleeders by the time old sol tickled the western tree tops. By an hour or so post the passage of the astronomical dusk boundary it was plummeted to 60, and 38 by dawn. This is no way to run a real warm up and is, sorry to admit using this word which I hate ... fake. We haven't had the metallic warm feel to the atmosphere. Where the wind is warm during the glome light period before the twilight. You know... pithy warmth. Doesn't even have to be hot for f'sake. Just confident your not radiating back to aching knuckles and stunted foliage. I think that changes soon enough. As I've advertised above and wasn't seemingly read by anyone heh it appears this week's the last of the gaslight pattern bs

Although super jealous, im happy for those getting rain today. Total .08” from yesterday.

Got a gut feeling we won't see the sun in July. At some point it has to reverse course right?

logic ? LOL !

Upper 10's-20's (30's along the Lake) this morning. Record/near record lows again across the area.

We did finally get another 1012+ mb today at Darwin though only barely (1012.15) helping to bring today’s SOI down to -9.25, lowest in a week though still not a strong -SOI. However, Darwin is forecasted to rise back very shortly. Looking ahead, the GFS not surprisingly (being that no other model had it) took away that tiny sfc low near Tahiti from its 5/12-13 maps and thus there won’t be those very strong -SOIs that an actual low would have generated. However, all of the models have general notably low pressure at Tahiti 5/14-6. That should result in notable -SOIs for those days. But because Darwin SLPs are also then progged to be somewhat BN, these won’t be as low as they could have been. Although Tahiti SLPs have been El Ninoish (- SLP anomalies) and will continue to be overall, Darwin SLPs still aren’t progged to be notably El Ninoish (+ anomalies). To get that, the N portion of the cold sfc highs coming from the cold regions to the south needs to extend more strongly further N into N Australia to get Darwin SLPs to go AN. They are forecast to rise back up modestly mid to late next week in N Australia on the N end of chilly high pressure, but it remains to be seen if they’ll rise that much at Darwin to result in a notably -SOI period then.

80s in May happen most years here - only 4 of 28 failed to reach 80 and the median for May's warmest is 85. As for this week, highs 50s-60s and frost advisory the next 2 mornings.

That’s one of the most beautiful maps I’ve ever seen.

Got down to 32 yesterday morning and 30 this morning at the house. Feeling more confident this will be our last freeze of the season

Low of 45 with .04" of rain. Mostly a delightful spring week ahead.

Thanks

Yesterday that looked more plausible. Today's indicators more tamed to seasonal+ But you're putting up charts that are upper 80s... as a support for your 90+ Do you see the logical problem there?

Looking at some significantly warmer periods coming up but should be active with the fropas too. However, the theme should be much different than we've seen with cool dominating. Should be warmer days winning out with a day or two of cooler temps post fropas

Agreed. Considering that is only the forecast through October and it will still be strengthening/warming at that point (the models have it peaking in November/December), with the added warming, it would almost certainly tie if not beat the all time RONI record since 1950, which was 1982-83, with 1997-98 being the 2nd. And it would also beat the record traditional ONI since 1950

SNE and a neighborhood near you

Euro shows Philadelphia flirting with the century mark this weekend.

55 / 32 after a high of 80 yesterday. Cool next 5 days with clouds / showers the theme. Upper cutof low moves through Thu - Fri. Brunt of rain 0.5 - 1.00 in the wettest case is Wed - Thu and Fri. By Saturday moderation to a warmer period is beginning. Much above in the 5 /17 - 5/24 >80 / next 90s with peristent ridge/warmth beyond there.

Maybe in the lower Ohio Valley…

Still winter until ~ the 13.5th to the 15.3rd ... Just beyond, obvious wholesale changes to this side/continental hemisphere would likely change the correction vectors from defaulting cooler to defaulting warmer - more of a behavior argument. The actual outlook itself moves temperature needle from averaging these 64/33s, to 76/51s ish (with option for more or less depending on alpine vs lower els) in the dailies. As an afterthought ... we have enjoyed some 8 consecutive months of suppressing warmth over our local Meteorological/geography. Really since last autumn, this has been an amazing sabbatical from the responsibility to objective awareness ( LOL ). A time in which we've been enabled to forget certain tendencies ... one of which, if the pattern is 'warm', the warmth always overperforms - at least to some degree. Suppression of that specific behavior. A hint to that being the case? We've put up modest positive anomalies, despite cool pattern persistent complexions. Another interesting observation (for me) that betrays that "lie", our monthly means are less than the 2nd to 3rd warmest 8 months in Global climate history the world has enjoyed, spanning the last half year: we've been in a persistent offset region. It all goes away when the cooler hemispheric curvature biases finally decays... With the advent/onset of an aggressive ENSO guard change coinciding with seasonal change, this at least intuitively would be a good time to see that happen, and to at last escape this winter's instilled recency bias. So, with this pattern that appears to be higher confidence ( post the 15th)... that will yield warmer than the current mere seasonal look - trust me. How much so? ... yesterday there was a bit of a heat wave signal. That appears to less so for that moment - unless you're a GEPs fan, which I'm not. But life outside the resonant cool pattern of the recent year appears favored.
