Thanks, Chris Keep in mind that even when assuming a bias, this is the coldest chart late May through early July overall for 80N+ compared to the same charts back to 1958. So, isn’t it an apples to apples comparison if one says it’s the coldest DMI chart for 80N for this period?

93/70 ouch

Wow im just nort of there

Wow im just nort of there

Checked the mesoscale discussion and didn’t realize we are well over 3000 CAPE currently in the region. You can see the best forcing is still out in WV with all the pop up storms before it moves east later. Got LL lapse rates heading to 8+ c/km. Our hodographs are weak but not terrible too. I made a more detailed write up of today last night in the severe thread but we could see something interesting today. Got a severe T-storm parameter of 4 right now as well!

I've always cut those hail estimates in half and it works well for me.

Flash flood emergency alert. Up to .52" now, pouring

Basically what I’ve told my wife for 20 years.

Share with us in the beltway!

Its crazy how this happened last July too only 10-20 miles to the north

I’ve said this in the past but man flash flood watches should not have been discontinued. A flood watch is far too broad of a product that tries to handle widespread synoptic setups that are more river flood based and pop up storms that dump over a small area and cause extreme flash flooding.

Currently it is 97/78. Feels like temp of 114.

It's working out well for our area. A good soaking, but the extremely heavy rain that's causing flooding is missing to the south.

This is such a great storm in Frederick, we have had lightning and thunder for at least 2hrs, really intense in the last 45mins.

I have a very limited view to the east and west. A drone would be fantastic as most of our storms come from the west or southwest.

totals of 6 inches or so near rocky hill

BULLETIN - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Warning National Weather Service Baltimore MD/Washington DC 213 PM EDT Thu Jul 9 2026 The National Weather Service in Sterling Virginia has issued a * Severe Thunderstorm Warning for... Southwestern Carroll County in north central Maryland... Northwestern Howard County in central Maryland... Central Montgomery County in central Maryland... Southeastern Frederick County in north central Maryland... Central Loudoun County in northern Virginia... Northern Fairfax County in northern Virginia... * Until 245 PM EDT. * At 213 PM EDT, severe thunderstorms were located along a line extending from near Linganore-Bartonsville to near Point Of Rocks to 6 miles north of Poolesville to near Leesburg to Purcellville, moving east at 25 mph. HAZARD...60 mph wind gusts and quarter size hail. SOURCE...Radar indicated. IMPACT...Damaging winds will cause some trees and large branches to fall. This could injure those outdoors, as well as damage homes and vehicles. Roadways may become blocked by downed trees. Localized power outages are possible. Unsecured light objects may become projectiles. * Locations impacted include... Germantown, Rockville, Gaithersburg, Leesburg, Olney, Damascus, Lansdowne, Lowes Island, Poolesville, Ashburn, Montgomery Village, North Potomac, Redland, Countryside, Purcellville, Round Hill, Boyds, Green Valley, Clarksburg, and Darnestown. PRECAUTIONARY/PREPAREDNESS ACTIONS... For your protection move to an interior room on the lowest floor of a building. Large hail, damaging wind, and continuous cloud to ground lightning are occurring with these storms. Move indoors immediately. Lightning is one of nature`s leading killers. Remember, if you can hear thunder, you are close enough to be struck by lightning. Torrential rainfall is occurring with these storms, and may lead to flash flooding. Do not drive your vehicle through flooded roadways.

Incredible wind and rain here right now, wow!

"Never assume malice for what is easily explained as stupidity."

Looks like a slight bow near Lucketts

Heavier stuff just clipping me now

Never underestimate stupidity. Now more than ever.

Up to 0.75" here now and really pouring. Very pleased.

Does Radarscope overdo the hail stuff? Says hail 2.75" on the warned storm... is that like max possible hail?

Concerning...Severe potential...Watch likely Valid 091805Z - 092000Z Probability of Watch Issuance...80 percent SUMMARY...Damaging wind gusts are possible as convection continues to intensify and move eastward this afternoon. A watch is likely. DISCUSSION...Convection along a stationary boundary has shown modest intensification over the last hour near the MD/PA border. Additional convection is developing along the Blue Ridge. Sufficiently strong westerly winds across the Ridge will eventually move convection to the east. Furthermore, around 30 kt of effective shear will be present allowing for stronger storm cells and linear structures. Low-level lapse rates will continue to steepen this afternoon, though cloud cover has been greater in the vicinity of the Chesapeake Bay. Given the potential for one or more clusters to evolve this afternoon, a watch is likely to address the threat for damaging wind gusts. ..Wendt/Hart.. 07/09/2026
