Spread out over two days may help, but this increasingly looks like it has high end potential somewhere.

Someone is getting destroyed by flash flooding. It won’t be that widespread, but that signal means damage.

Steady light to moderate rain in Falmouth the past half hour. Can definitely use it down here.

this is a thread about the current heat and storms impacting the DMV. Are you lost?

Understood. Not trying to cause issues. So many topics in wx are inexorably tied together, it's not always easy to parse things out neatly. And sometimes discrete topics discussed together are relevant and provide value. Yes, I know that is subjective, but that's par for the course.

lmao this dude just comes in here - and completely unprompted - starts an argument about climate change.

Had a 41 MPH gust with the storms, but still haven't cracked 0.10" of rain. Temp is down to 72.3F.

inside the beltway has been heavily urbanized since the mid 20th Century - so, not really sure UHI explains it (particularly the immediate area around DCA). Maybe if you're looking at a graph of IAD or something, sure. But the location around DCA has been built up for a long, long time. That's like saying UHI explains recent changes in Central Park.

ICON has some big numbers too.

Not at all. Not implying anything in this case. I am big into wx reporting stations around the globe and keep track of all METAR/TAF/SYNOP/BUOY.

Missing flooding rains by 15 miles

Thanks for posting the graph! You can see the big years clearly. 1980, 1988, and 2012 show up well. I agree the long-term trend is up, but it's not strongly. IMHO, the biggest factor is the UHI. I'm originally from the BOS area. Logan Airport has a bunch of issues w/ temp, precip, and snowfall. For temp, once the airport was built, the obs were moved from the downtown. Through the late 70s, the wx equipment was next to the building that housed the NWS at the airport. Then the wx equipment was moved to the center of the runways. Makes sense from an aviation standpoint. But this actually made things *cooler* in the summer b/c the runways are surrounded by water on 3 sides (landfill). So BOS hit 102 on July 21, 1977, and then did not hit 100 again until July 14, 1995. It hit 100 many, many times before 1977. It took 18 years for the UHI effect to get BOS to 100 again, and it has no problem hitting that since. Just shows how even minor changes to wx equipment location can make a sig difference!

Ah, listening to the summertime hum of neighborhood generators while sipping room-temperature vodka. 72F

Dodging drops in Henniker (NH) at sunset.

Just say what you want to say.

I seem to recall a few sites got the ceilometer upgrade going back several years, but I haven't heard much since. AWOS-4 does not mention it has this upgrade.

Not as crazy as last night but a bit more rain at a little over 1/2”.

Man times flies. I know most AWOS’s were upgraded to 3PT for precip ID and temp remarks (LCI and EEN got it up here), but I thought it was more recent than that. But now that you mention it I do remember the old 20 minute obs that used to come out of there with the original AWOS. BTW, whatever happened with the 25k ceilometer rollout? I thought that was happening 10-15 yrs ago and instead only some of the manned sites report/augment it in. There’s nothing more stupid in weather reporting than reporting an overcast layer at 13kft as “CLR”

Storms rolled through and cooled it down nicely for the Great Falls fireworks. 72 degrees. Happy 250th!

see if you can spot the trend!!!

Barely a drop

And I just came across this. An AWOS was just commissioned at the Pier 7 Heliport in Baltimore. https://www.airnav.com/airport/4MD So a site to compete w/ the furnace that KDMH is? LOL. The site METARs are not on the WMSCR/NCEP feeds currently. Not sure if they will be, but if they are added, I will let the forum know. No AWOS phone number was listed in the NFDD entry (see attachment).

4th Of July Weekend thunderstorms and fireworks. Looking to add to this over the next couple days... Hopefully.

That looked like a different cell that developed right over you guys
