I usually go in July every year.. It actually doesn't bother me when I'm there. but hate when dews get 70 plus at Home.. I guess its a different vibe or I'm on vacation and don't care

Hmmm Mesoscale Precipitation Discussion 0402 NWS Weather Prediction Center College Park MD 1211 PM EDT Sun Jun 08 2025 Areas affected...Portions of the Central Appalachians and Northern Mid-Atlantic Concerning...Heavy rainfall...Flash flooding likely Valid 081610Z - 082210Z SUMMARY...Areas of moderate to heavy rainfall will continue through this afternoon with an expectation that scattered thunderstorms will develop and produce heavier rates. Given the moist and sensitive antecedent conditions, the additional rainfall is likely to result in some runoff problems and flash flooding. DISCUSSION...The midday GOES-E visible satellite imagery along with regional radar data shows areas of moderate to locally heavy rain falling over portions of western and southwest PA down through the MD/WV Panhandles and into northern VA. This rainfall is being driven by the arrival of a shortwave trough from the OH Valley which is promoting a northwest to southeast corridor of isentropic ascent and frontogenetical forcing along and just poleward of a warm front lifting gradually northeastward into the region. Meanwhile, solar insolation is seen taking place farther west across central and northern WV and western VA which is allowing for some CU/TCU development over the higher terrain. Surface-based instability is expected to continue to increase going through the afternoon hours, and with convergent flow along the front and orographic forcing over the higher terrain, there should be the development and gradual expansion of some heavier shower and thunderstorm activity over the next few hours. It should be noted that moist low-level southeast flow is expected to become better established into the Blue Ridge this afternoon as well, and this may yield some locally more concentrated areas of convection in these areas. The environment is pretty moist and the 12Z RAOBs at KPIT and KIAD showed 1.42 inch and 1.62 inch PWs respectfully which are at or just above the 90th percentile of daily climatology. This overall environment should favor at least above average rainfall efficiency across the region and especially with some of the forcing that will be occurring this afternoon in the warm layer of the column. Rainfall rates with the instability driven convective elements this afternoon from southwest PA down through northern VA will likely be quite high and capable of reaching 1.5 to 2 inches/hour. The 12Z CAM guidance suggests that some localized rainfall totals by this evening may reach as high as 2 to 3+ inches where some of the slower moving cells evolve. Given the wet antecedent conditions and high rainfall rates, isolated to scattered areas of flash flooding are likely. Orrison ATTN...WFO...AKQ...CLE...CTP...LWX...PBZ...RLX...

June 8 Southern Plains Severe Outbreak

Yesterday was a significant (derecho?) severe weather day for AL/GA/SC. There were late night supercells producing wind damage in MS/AR, long after the squall line exited the area.

We're still holding onto mostly sunny here although I do see clouds building to my south.

73/51 Back in the sweet spot for temps/dews.

June 8 Southern Plains Severe Outbreak
Powerball replied to Powerball's topic in Central/Western States
In addition to the squall line itself, CAMs have hinted at some discrete supercells ahead of it impacting the northern DFW suburbs. That will have to be watched closely as well. -
I still don't know what to make of this setup. Few CAMs have a handle on the band of showers currently pushing southwest to northeast across the area. The ones that do have these showers don't really do a whole with convection lot later today. The HRRR looks more interesting, but it isn't handling the current stuff well, and while its reflectivity looks good later, there isn't much instability. The shear (both deep layer and low level) is intriguing for sure, but I wonder if it's just going to be too stable for much of the area to really have a threat. My best guess is that any severe threat stays south and west of a Winchester to Culpeper to Quantico line, but we'll see how temperatures evolve for the DC-Baltimore corridor.

June 8 Southern Plains Severe Outbreak
Chinook replied to Powerball's topic in Central/Western States
The latest HRRR has a large heavy squall line heading towards Fort Worth tonight. I think these could be storms with a higher chance of wind damage. Parameters are going to be very high for supercells in the area where storm-relative helicity gets locally higer. -

This made me laugh (I think it was their delivery)... https://x.com/TheShawnHendrix/status/1931718406912311314?t=DexunR-LH_Bybk9Bix1nMQ&s=19 -
Clouds won out here CNJ 80% cloudy but no rain temp dropped from 76 to 72.
-
That Euro run yesterday was on the right track with the best chance of rain today being during the late morning / early afternoon along the warm front boundary. That area of rain is there, but it's fairly splotchy and progressive, so while some localized areas will get soaked, it doesn't appear that widespread big totals are likely.
-
Light rain showers moving in. Heavier band rolling through now. I will take it!

0.63" of rain last night. Smoky skies today with another round of stms possible. Pretty seasonable June so far. Had one hot day on the 2nd, but other than that, pretty decent. Precip is most welcome. Forecast looks good.
-
Maybe once we complete the switch back to -AMO we will have summers like 1993 and 1999 and 2002 and 2010 again.
-
Did you see the temperatures I posted from 2010? WOW, we just need a summer as dry as that to get some nice dry heat.... 101 degrees with a dew point of 45 is some of the cleanest air we can ever get around here. High water vapor in our air is a recipe for air pollution in the summer.

Radar not looking good for flooding rains today. Have picked up .40" since overnight, though.

It’s just too wet in this new climate to ever see the reservoirs run a low as they did back in 2001-2002 leading to water rationing in NYC. We’ll have to monitor this pattern as the summer progresses. Since more Gulf Hurricane activity riding north inland along the APPS like recent years could create major flood concerns heading through the summer and fall. https://www.nyc.gov/site/dep/water/reservoir-levels.page

"Multiple rounds of scattered severe thunderstorms look to push across the region this afternoon and evening (between 2-9pm) as a warm front lifts through. The primary threat with storms will be damaging winds and locally heavy rainfall. An isolated tornado or two is possible mainly south & east of DC. Have a way to get warning via phone, tv, or computer. #MDwx #VAwx #WVwx #DCwx" From LWX Facebook page posted an hour ago

and a high of 101 with a dew point of 45 wunderground lists the temp as 99 on this fateful day but in between hours JFK hit 101 as shown in the records July 4th 2010 was my favorite July 4th of all time, in a stretch of 3 out of 4 days at or above 100 degrees and a nice dry heat!! https://www.wunderground.com/history/daily/us/ny/new-york-city/KJFK/date/2010-7-4 Summary Temperature (°F) Actual Historic Avg.

Legitimately got surprised overnight, probably the best thunderstorm in a year or 2 here ... 1.25

I'm so glad it's not here.
