Central PA Spring 2026 Discussion/Obs Thread
Yardstickgozinya replied to Voyager's topic in Upstate New York/Pennsylvania
I only included discussion specifically regarding localized threats. The full discussion is in the link below. No science to it, just a roll of the dice and some twisted intuition. I sense a convactive over achiever coming on today. Not that it will translate to today, but cpa had some decently, elevated parameters that went the waste yesterday . The cap fully eroded over most of the area by mid-afternoon, but a lack of forcing and meager mid-level's hindered any convective development. Although simple details, I think frontal timing and orientation are conducive to localize overachievement, especially if the sun can get that surface baked for us cpa southernish. SPC AC 010548 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1248 AM CDT Wed Apr 01 2026 Valid 011200Z - 021200Z ...Ohio Valley/Mid-Atlantic... West-southwesterly mid-level flow will be in place over much of the eastern U.S. today. At the surface, a quasi-stationary front will be located in the Ohio Valley from southern Indiana east-northeastward into far southern Pennsylvania. Surface dewpoints in the upper 50s and lower 60s F to the south of the front will contribute to weak instability by early afternoon. Increasing low-level convergence near the front and warming surface temperatures will result in scattered thunderstorms during the afternoon. Several short line segments are expected to form and move eastward across the Ohio Valley into the central Appalachians. 0-6 km shear in the 25 to 35 knot range and steep low-level lapse rates will support isolated severe storms with potential for damaging wind gusts. A low-end tornado threat will also be possible. https://www.spc.noaa.gov/products/outlook/day1otlk.html -

Mountain West Discussion

It has been absurdly snowy this month in Juneau, Alaska (upwards of 6 feet of snow in March), in fact they have now set a new record for snowiest winter! https://www.ktoo.org/2026/03/23/juneau-breaks-march-snowfall-record-but-not-the-winter-record-yet/ -
71 out at 12:30am. Struggling to fall asleep as we are not wanting to turn the air on.

Exciting day for space enthusiasts tomorrow!Live updates: Will Artemis II launch tomorrow? Florida's weather outlook and mission status updatesLIVE UPDATES Last Update May 1, 2026 at 10:44 PM EDT NASA is targeting an April 1 launch for the historic Artemis II mission, with meteorologists currently tracking a favorable 80% "Go" weather forecast at Florida's Kennedy Space Center. Follow our live coverage for real-time radar analysis, countdown milestones, and the latest mission status as four astronauts prepare for humanity's first crewed journey to the Moon in over 50 years. https://www.foxweather.com/live-news/live-updates-will-artemis-ii-launch-tomorrow-florida-s-weather-outlook-and-mission-status-updates#google_vignette

Happy June-like start to April, Weather family.

May 21, 2026 3:56PM EDT Tornadic supercell over Winchester, VA already responsible for at least two confirmed tornadoes in eastern WV continues to move just south of due east into a more favorable environment characterized by extreme instability (5000+ J/kg MLCAPE), strong effective SRH (300-450 m2/s2) and strong effective bulk-shear (60+kts). With low LCLs owing to surface temps around 90F with dewpoints around 80F, the environment is set for cyclical potentially strong to violent tornadoes as this supercell or any others that manage to form through the cap (warm-layer aloft) near the warm front move E to ESE. This an unusually dangerous situation for the Greater DC metro region as this is where the warm front is slowly lifting through from southwest to northeast. Take any tornado warnings or potential tornado emergencies issued this afternoon and evening especially seriously. The greatest potential of any particularly intense tornadoes will be between now and about 8-9pm when the subtle shortwave responsible for this supercellular storm activity exits to the east. Outside of the tornado threat any storms this afternoon and evening will be capable of dropping up to 4 inch diameter hail as well as producing significantly severe wind gusts (80+ mph) thanks to the steep 8+C MLLRs and fairly large downdraft CAPE available. There will be a lull in severe activity by the late evening hours before another round of more widespread storms, possibly in the form of an MCS or to move in from the west as a result of a stronger shortwave moving around the crest of the ridge of high pressure draped over the southeastern US. Despite the late night/ pre-dawn timing of these storms (midnight-6am) there could still be a decent severe wind threat as well as a risk of severe hail and a couple tornadoes owing to MLCAPE still around 2500-3000+ J/kg, 50-60kt effective bulk-shear and still strong low-level shear (Effective SRH in excess of 250m2/s2). Friday will introduce a still hot but less humid day with only a slight chance of isolated afternoon storms, mainly in the mountains.

A lot of hype on social media over Thursday.
-
It's getting crunchy here.
-
Another stormy night on the way!
-
Full PT by evening? Bordering on priapism I bet! LOL.
-
Awesome shot. Don't get many without leaves on the trees.

Just a weird weather day all around in NE. WWA in NNE, 80 on the sound, a big backdoor pushing hard in EMA, and now some big bangers/downpours. Better than a ULL cutoff with misery I suppose.

Left Worcester a bit after 8 and it was a chilly mid 40s, back in the valley it's a nice 66/55F.

40° +RA 0.93”

And that they did!

Was hoping for a storm but another miss north and south lol. At least this time around we had one full nice day before the bust.

You can see drifting up to 8 inches tall from 2-3 inches of accumulation already off the Woolly Lot cam as of 6.30pm Mammoth local time! https://www.mammothmountain.com/on-the-mountain/mammoth-webcam/woolly-cam Winds are setting up; temps have fallen 3-4 degrees in past hour; road surfaces caved fully about 90 minutes ago. Snow will continue into the evening. Modeling indicates possibly a couple inches of water equivalent. My thinking is they pick up 12-18 inches by late tomorrow; Tahoe will get 20-34 inches by same timeframe.

Well, that was some of the hardest rainfall I’ve ever seen. About .80” in 20 minutes.

Oh yes, winter is in the rear view…it was very good, but let’s do Spring now. No desire or need for cold and damp now.
