Great video of the severe storms moving in yesterday from a boat in New York Harbor.
-
Looks like DCA had a low of 84. Canaan nwr had a low of 58. Probably felt cold in comparison.
-
Ensembles are showing a lot of rain as the heat breaks. Would not be surprised to see it go from drought conditions to flooding in a hurry.
-
It’s been hot and humid in northern PA. Had storms move through near midnight that were prolific lightning producers. Good old fashioned storm borne of heat and humidity. You could tell the whole atmosphere was ready to go and has reset back to being unstable overnight.

This time stations like Newark and Harrison had to reach 105°-106° for NYC to finally reach 100°. LGA also made it to 104°. This suggests that NYC would have probably been at least 104° if the ASOS hadn’t become overgrown by the trees since the 1990s. This matches the past times our area experienced 103°+ heat before the tree growth near the castle became an issue.

I guess my question for you is who even has climate change as the preferred narrative anymore? The White House thinks it’s a hoax, all of “mainstream media” have had their owners replaced with people who are at the bare minimum sympathetic to climate denialism, and in general the political zeitgeist has moved on. If anything, the current political climate has denialism as the ideology it would push. Of course, I agree that there are social media accounts trying to hype up all of us dying but they are doing that for their own fame and any commentary on climate change is secondary to their own profit.

Excessive Rainfall Discussion NWS Weather Prediction Center College Park MD 417 AM EDT Sat Jul 4 2026 Day 2 Valid 12Z Sun Jul 05 2026 - 12Z Mon Jul 06 2026 ...THERE IS A SLIGHT RISK OF EXCESSIVE RAINFALL ACROSS PORTIONS OF THE MID-ATLANTIC... An east-west orientated front boundary will be sprawled across the Northeast/northern Mid-Atlantic region during this period. Moderate instability combined with PW values of 2+ inches are expected to overlap near the frontal boundary to produce periods of heavy rainfall. This area historically is more prone to flash flooding due to terrain influences and more sensitive hydrologic schemes thus maintaining the Slight Risk for excessive rainfall for this part of the region. Backbuilding and training of thunderstorms may be possible. Scattered flash flood concerns exist over the central Mid- Atlantic with an increasing risk of heavy convection over portions of Pennsylvania down through the Washington DC- Baltimore- Philadelphia corridor. A broad Marginal Risk area spans from eastern Oklahoma/Kansas eastward to the Mid- Atlantic/southern portions of the Northeast. -
Probably good thing we dont have shear near 40 kts .DISCUSSION... KEY MESSAGE 1...A highly impactful Independence Day lies ahead today with extreme heat and an Enhanced Risk for severe thunderstorms. Anomalous heat and humidity remain a fixture across the area. Based on the latest 07Z/3 AM observational data, temperatures generally range from the mid 70s to mid 80s. This is accompanied by dew points in the 70s which is yielding overnight heat indices between 85 to 95 degrees. Skies remain mostly clear although there is still residual convective debris drifting southward from central Pennsylvania. Before convection enters the picture, it will be another day of record warmth across the Mid-Atlantic region. Using 850-mb temperatures as a proxy, forecast readings should be around 22-23C which dry adiabatic mixing favors another 100 degree day. Adding continued tropical moisture in place will support heat indices pushing into the 105 to 110 degree range. Extreme Heat Warnings are in effect from 10 AM until 9 PM for areas east of the Blue Ridge. Given an uptick in forecast heat indices, have upgraded to warnings over north-central Maryland down across the eastern West Virginia Panhandle into portions of the Shenandoah Valley. Otherwise, outside of mountain locations, Heat Advisories will be in effect until 8 PM this evening. Unlike previous days which were free of convection, a collapsing ridge will lift the subsidence that has persisted the last few days. Although mid/upper heights remain anomalous in nature, forcing from an approaching shortwave will aid in more widespread showers and thunderstorms. One unique aspect to the thermodynamic environment is an elevated mixed layer (EML) which has shown up in the last 4 IAD sounding profiles. Within this layer around 750-600 mb, lapse rates continue to run between 8-9 C/km which is unusually steep for this area. This is contributing to some impressively large amounts of instability, generally in the 3,000 to 4,000 J/kg. Within the deeply mixed boundary layer, substantial downdraft CAPE (DCAPE) is evident with values around 1,300 to 1,700 J/kg. Although vertical shear is only around 20 to 25 knots, any storms able to tap into the robust instability will be capable of damaging winds. Some of this could be locally destructive with gusts up to 60 to 75 mph. With all of the above in mind, and ample high-resolution model support, the Storm Prediction Center has upgraded areas east of the Blue Ridge to an Enhanced Risk today. This upgrade would support a more widespread footprint of severe thunderstorms this afternoon and evening. Looking a bit more closely at today`s setup, convective initiation likely will be more mesoscale in nature. This would include the climatological lee-side trough, bay and river breezes, as well as any remnant outflows from earlier convection. Multiple rounds of thunderstorms are possible given so much instability in the troposphere. The primary signal east of the Blue Ridge is in the 3-9 PM timeframe, slightly earlier to the west. Damaging to locally destructive winds are the main threat, with any chance for large hail being minimal given the summertime freezing levels. Although the convective signal is strongest during the afternoon to early evening hours, residual storms could easily impact those with outdoor plans for fireworks this evening.

2026-2027 Super El Nino
bluewave replied to Stormchaserchuck1's topic in Weather Forecasting and Discussion
We have been experiencing record heat here in the East at times going back to March related to the record breaking subtropical tropical ridges from 30N to 45N. Most times very strong to super El Niños feature more troughs and low pressure at these latitudes at this time of year. The ridges are usually further north on the continent in Canada. This has lead to the mid-latitude Atlantic SSTs joining the very warm mid-latitude Pacific SSTs. This is probably related to the ongoing expansion of the subtropical ridges over the years. Plus we have very extensive drought in the CONUS at this time. Also when forcing shifts back to the IO and MC we tend to see the peak warmth and ridging in the East. The reason the -PDO and +AMO pattern has been so persistent in recent years is due to these strong ridges leading to lighter winds and more sunshine warming the ocean surface below. -

NWS verbatim SPC on today's severe potential. -- Highlight Changed Discussion -- 237 FXUS61 KCTP 040916 AFDCTP Area Forecast Discussion National Weather Service State College PA 516 AM EDT Sat Jul 4 2026 .WHAT HAS CHANGED... * Extreme Heat Warning upgrade for Fulton, Franklin, Perry, and Cumberland Counties && .KEY MESSAGES... 1) Breakdown of early July heat wave promotes an increased risk of damaging thunderstorm wind gusts and potential flash flooding through Independence Day weekend && .DISCUSSION... KEY MESSAGE 1: Breakdown of early July heat wave promotes an increased risk of damaging thunderstorm wind gusts and potential flash flooding through Independence Day weekend Final day of heat headlines with max heat indices reaching 100-110 degrees to the east of the Allegheny Plateau. The breakdown or ending process of heat waves is often marked by bouts of severe weather - and that will likely hold true through the July 4th holiday weekend. Clusters of storms are projected to develop through the weekend in a very moist, unstable, modestly sheared environment and will have the potential to produce localized to perhaps widespread damaging wind gusts - especially of they can grow upscale and sustain strong cold pools. A threat for heavy to excessive rainfall will also be in play given high pwats and efficient rainfall/hourly rates. SPC and WPC outlooks were largely unchanged for this cycle. https://forecast.weather.gov/product.php?site=CTP&issuedby=CTP&product=AFD&format=CI&version=1&glossary=1&highlight=off -

Happy Independence to those who acknowledge the United States is the greatest country in the world ,and all those who serve and have served America. Stay safe out there, especially, you extreme southeastern folk. Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0100 AM CDT Sat Jul 04 2026 Valid 041200Z - 051200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS PORTIONS OF THE MID-ATLANTIC... ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF THE CENTRAL/SOUTHERN PLAINS... ...SUMMARY... Clusters of storms will move across parts of the Allegheny Plateau into Mid Atlantic, with potential for widespread damaging wind. Additional thunderstorms are expected across the Great Plains Saturday afternoon and evening, posing a risk for damaging wind gusts. Large hail is also possible across the Great Plains. ...Synopsis... Height rises will continue across the western US, with more zonal flow across the central US and upper-level troughing across the Northeast and Quebec/Ontario. A modest belt of westerly flow around 30-40 kts will move through the trough in the Northeast/Mid-Atlantic. A compact shortwave trough with enhanced westerly flow will move through the flow across the Central Plains. ...Eastern Ohio Valley into the Mid-Atlantic... Activity will likely be ongoing across some portion of northern PA into northern NJ this morning. This will likely contribute to lingering cloud cover and more muted daytime heating/recovery with northern extent. South of the morning precipitation, strong daytime heating and warming is expected, with temperatures climbing into the 90s to 100s F. A plume of steep mid-level lapse rates is already in place across the region from WV into VA/MD/NJ. With daytime heating, low-level lapse rates are expected to increase with moderate to strong instability by the afternoon. Deep layer shear profiles will be generally weak, with better shear to the north. Nonetheless, several thunderstorm clusters are expected to develop across the Blue Ridge Mountains/Shenandoah Valley moving north and eastward though the afternoon. These will have the potential to produce widespread damaging wind, especially if clusters can grow upscale and develop strong cold pools. https://www.spc.noaa.gov/products/outlook/day1otlk.html -
