2026-2027 Super El Nino
PhiEaglesfan712 replied to Stormchaserchuck1's topic in Weather Forecasting and Discussion
94-95 was really skewed by February. The rest of that winter (November-January and March) absolutely torched in the Eastern US and was actually cool in the West. I'd say 14-15 was the best match for 25-26. -
Central PA Summer 2026 Discussion/Obs Thread
mahantango#1 replied to Voyager's topic in Upstate New York/Pennsylvania
US National Weather Service State College PA Favorites ·oSnesoprtdah6a1lm6h2himht63569uagm0ct73u14i7tf9gt2c1i2tff16i · A strong low pressure system is expected to bring scattered severe thunderstorms on Tuesday, July 21st. Damaging winds are the primary threat, though all severe weather hazards may be possible. Remember that central Pennsylvania only sees around 5-6 Enhance risks a year. Confidence continues to increase for severe weather on Tuesday. -
50 for the low here, I see 48 up the road at KMGJ, I nice break from the warmth.

52 here; lovely morning.

"In terms of rainfall, it looks like areas along the southern CT, south coast and the Cape and Islands stand to see the most rain, at the expense of interior Southern New England. Ensemble 24-hr QPFprobs paint moderately high (40-70%) probs of rain totals AOA 1 inch along the southern/southeast coast, and lower (< 40%) to the north and west. These areas have been getting quite a bit of rain lately, especially out over Cape Cod. " Rinse and repeat.

Down to 56. Feels chilly out

Chester County PA - Analytical Battle of Actual vs. Altered Climate Data
chubbs replied to ChescoWx's topic in Climate Change
Nope. The Chesco COOPs cool significantly relative to the SE PA Division data from the PA climatologist. Regression isn't a good tool because the station changes are sudden not gradual and you picked an interval that started after the initial Coatesville move and ended before the West Chester move took full effect. If you widen the interval to 1941-1975, the difference in slope is large. Per table below, comparing the five years before the first move and the five years after the last move, the Chesco COOPs cool by 1.7F relative to the SE Pa Division. Note that the Pa SE Division includes the Chesco Coops so the two items compared are not independent. For that reason it is not surprising that the delta for the SE PA is slighly smaller than ABE. Funny seeing you try to try one dead end after the other to discredit what the the raw data from Chester County clearly shows. The 3 stations each cooled significantly after the 1945-1970 moves: first Coatesville cooled relative to Phoenixville and West Chester; then Phoenixville cooled relative to Coatesville and West Chester; and finally West Chester cools relative to Coatesville and Phoenixville. You aren't going to change what the data clearly shows. -
Absolutely comical split to basically whiff our area - light rain for 45 minutes. That has happened so much this spring and summer - not sure why but it has been happening a lot.

It would be different in here if something exciting happened occasionally but it just doesn’t anymore. Straight up boredom around these parts for the last decade. I agree with you that the vast majority of people want yesterday’s weather, but the people in here at least want excitement. It’s been so boring that we have been left to post about rain and smoke. Occasionally a blizzard impacts southeast Mass but that’s about it.

2026-2027 Super El Nino
bluewave replied to Stormchaserchuck1's topic in Weather Forecasting and Discussion
I am wondering if the reason that the standard 2020s summer -PDO/+AMO atmospheric state pattern has dominated the first half of summer rather than an El Niño type is due to the standing wave centered more in the Southern Hemisphere? El Niño has garnered a lot of attention, and this looks to be a large event for the reminder of the year. El Niño is related to cooler, wetter than normal summers in the US while La Niña warmer drier summers. I think the summer of 1988 cemented the impression that La Niñas support continental heat domes, heat and drought for the US. But looking at the temperature pattern across the US this summer so far it seems to be just the pattern that recent summers have settled in to regardless of the phase of ENSO. So far, in my opinion it is hard to observe the impact of El Niño on US weather just yet. - Today

Little taste of fall this morning. . -
Beautiful outside. 57F

Upper 50's morning of July 20th not too bad.

While there is typically relatively high uncertainty for nascent, not well defined systems, I agree with NHC and posters here that the uncertainty here is unusually high due to the forecast coast-parallel track and the strong dependence of the track later this week on how quickly future Bertha gets organized in the next day or two. I go into the potential scenarios and all of the details here: https://hurricanehacker.substack.com/p/tropical-storm-bertha-likely-to-form?r=etzas

E PA/NJ/DE Summer 2026 Obs/Discussion
LVblizzard replied to PhiEaglesfan712's topic in Philadelphia Region
The NAM and HRRR look drastically different for Tuesday. The NAM has widely scattered storms in eastern PA while the main line stays in western PA and dissipates as it reaches this area. The HRRR plows a strong line of storms through the region on Tuesday evening. It’s a decent setup without as many fail modes as Saturday…but we still need things to come together the right way. It’s not easy to get a severe outbreak around here. -

Yeah July hasn't been bad other than that incredible heat wave to start the month. Pretty good that we're gonna end up with a near normal month despite that record early heat. I'm glad that we've gotten much more rain this month too.
