🇺🇸DC⚡️Storms @DCstorms

Near Burke @capitalweather

Immense storm damage in Fairfax County, Va just south of George Mason University. Fire officials on scene tell me, as far as they know, everyone here in the Chatham Towne community is uninjured. Power remains out.

Major tree damage from storms reported in Burke. NWS says probably straight line winds, not a tornado. Many trees, wires were toppled. Even some damage to siding/shingles. Here's some more info and pics: capitalweather.com/major-tree-dam… Were there storms bad for you? Thanks for any reports.

Here are some estimated outages across the DMV. The greatest concentration is in Fairfax and Stafford counties, with 20K + without power. @ScottSumnerWX

@wx_garcia Downburst can easily have tornado level winds. They’re nasty and super dangerous

A severe thunderstorm watch has been issued for parts of DE, DC, MD, NJ, PA, VA, WV until 9 PM EDT

A corridor of brief tornadoes are becoming increasingly possible across the Mid-Atlantic indicated by live sfc. analysis and satellite and imagery.

MONDAY, June 22 – portions of southern Pennsylvania, northern Maryland, New Jersey and the northern Delmarva Peninsula are at risk of an isolated tornado today. Low pressure forming along a frontal boundary will enhance vorticity (spin), and we also have some helicity (twist) along a warm front lifting north. It's unclear how far north that warm front will get. If it struggles to advance north, a sneaky tornado risk may exist near Washington D.C. or Baltimore too.

Warm front has just passed through DC, with winds turning to the SE at the surface. With continued southerly flow, expect dew points to rise to near 70 this afternoon and with filtered sun, instability will be quite high.

There is your watch. Up for our entire region until 9pm.

A severe thunderstorm watch will be issued for our region in the next hour or so. ⛈️ As expected, SPC notes in their discussion they are most concerned with damaging wind potential, but note that an isolated tornado or two can't be rules out with the shear profiles. 🌪️ We'll be tracking storms as they shift east!

Closely monitoring potential for some strong to severe storms today (Monday). * Most likely timing: 3-8p, prob 4-7p Beltway area * Expect heavy rain, lightning, + poss damaging wind gusts in strongest storm * Brief tornado poss in region; maybe highest chance toward N Md, Pa Briefing at this link: capitalweather.com/scattered-stor…

Kicking the week off on a bit of a busy note with severe weather possible this afternoon and early evening. Showing latest RRFS & HRRR modeling with 1pm-12am time frame. Similar to more recent setups, the best forcing an most unstable environment today appears to be mostly around the I-95 and in our eastern zones. Storms probably start more hit & miss in our western areas and then congregate as they shift east. Damaging winds the primary concern. Isolated tornado threat is there as well however, with the early afternoon mesoanalysis data highlighting two zones that appear to have the best shot for an isolated tornado bring (1) northeast MD, southeast PA, southern NJ and (2) Southern MD, Northern Neck VA. We have world cup coverage but we'll be scanning all day of course and keeping folks updated!

STORM UPDATE: 1:23 PM Mon June 22 🌡️Temps have reached near 90℉ around Baltimore and southward... while sill the upper 70s to the north. While the front is trying to push north, the places in the heat now will have the great chance for Severe Weather. 👍 Storms will form and track for most areas.. with highest risk for severe weather near I-70 and Southward. This includes Southern Maryland and Eastern Shore by evening. 👀 This is the Warm Front and Focus for added spin with storms later. 💻⛈️ Computer Guidance still points towards storms developing with multiple rounds. I am showing the HRRR Model as it still appears to have initialized best. ⏰4 PM to 10 PM ⚠️ I suspect A 'Watch' will be issued for POTENTIAL Severe Thunderstorms and maybe tornadoes. 💨🌪️ Damaging Wind The greatest Risk. A Tornado is possible but odds are low. 💦 Flash Flooding may also result from 1"/Hr+ Rainfall Rates... and some places getting multiple cells.

After a quiet finish to the weekend, hazardous weather returns to the area on Monday with the potential for strong/severe t'storms as well as some flash flooding. Highs also return to the low 90s. Ensure you have multiple ways to receive weather alerts. #MDwx #DCwx #WVwx #WVwx

Looking at the 18z data, I am thinking northern and northeastern MD into southeast PA will have the best chance for tornadoes, and I would be shocked to not see a 5% risk included. Supercells moving along the WF will be capable of producing isolated tornadoes.

⚠️⛈️ Strong to severe thunderstorms will be possible tomorrow afternoon and evening across the region with a level 2 out of 5 risk in place. Damaging winds look to be the primary threat but a few tornadoes cannot also be ruled out. The highest tornado threat will depend on where the warm from sets up across the area. We could also see two separate rounds of storms tomorrow which would increase the threat for scattered areas of flash flooding in the heaviest storms. Make sure to stay weather aware and have ways to get alerts! #vawx #mdwx #dcwx #wvwx

Has it felt less humid than normal to you this month? From New York to D.C., there have been pockets of below-average humidity! Humidity, as measured by the average dew point, has generally been near average along the East Coast and across the Midwest, with a few exceptions. That's a big change from last June, which was very humid. Areas from the Southwest to the Deep South have been most unusually humid. Extra heat and moisture is flowing into some of this stretch from a marine heat wave in the eastern Pacific. Here's how humid each state has been compared to average: Texas: +5.1˚F New Mexico: +4.8˚F Arizona: +4.0˚F Louisiana: +3.9˚F Arkansas: +3.8˚F Maine: +3.5˚F Oklahoma: +3.4˚F Mississippi: +3.4˚F California: +3.2˚F Vermont: +2.8˚F Alabama: +2.7˚F New Hampshire: +2.7˚F Missouri: +2.3˚F Minnesota: +2.2˚F Kansas: +1.5˚F Tennessee: +1.4˚F Florida: +1.3˚F North Dakota: +1.0˚F Michigan: +0.9˚F Georgia: +0.9˚F Iowa: +0.9˚F Wisconsin: +0.9˚F Illinois: +0.8˚F Massachusetts: +0.6˚F Indiana: +0.4˚F Kentucky: +0.2˚F Rhode Island: +0.2˚F New York: +0.2˚F South Carolina: -0.1˚F West Virginia: -0.2˚F Connecticut: -0.4˚F Ohio: -0.4˚F South Dakota: -0.5˚F New Jersey: -1.1˚F Pennsylvania: -1.1˚F North Carolina: -1.2˚F Nebraska: -1.3˚F Montana: -1.4˚F Maryland: -1.6˚F Washington: -1.9˚F Delaware: -2.1˚F Virginia: -2.3˚F District of Columbia: -2.4˚F Colorado: -2.7˚F Oregon: -3.6˚F Nevada: -3.7˚F Utah: -4.0˚F Idaho: -4.4˚F Wyoming: -4.7˚F

Here is the latest RRFS simulation for tomorrow's system... from 12pm Monday - 12pm Tuesday. Heaviest storms will likely be from 3pm-midnight tomorrow.
