📸The only shot I was able to get today, a tilted updraft exiting over Sandbridge that did have modest rotation on radar, but not very evident on the surface.

Lets talk failure mode!

Early morning convection destroyed CAPE levels, and the surface low to our NW never really got going, this lead to no clear slot forming. That clear slot would have provided enhanced backed surface winds, as well as cleared out the “crapvection” we had allowing for CAPE values to climb back to values needed for severe storms/tornado supporting updrafts. Furthermore, the lack of capping in the environment had me especially puzzled when considering todays threat, when you have no capping (temperature inversion that allows for CAPE to essentially build and simmer until enough energy can break through it leading to robust updrafts), you get a bunch of slowly rising updrafts competing for the same moisture content, exactly what we saw today.

Looking back at Skew T’s I knew such a water bogged and low CAPE environment would have resulted in exactly what we got, which is is why I referred to failure modes as often as I did, but when you have the professionals at the SPC sounding the alarms, you would be foolish to down play such an event on a public forum, that could potentially result in loss of life or property in a worst case scenario.

Going forward I will provide my exact synoptic breakdown, then link to official resources such as the SPC, who you should always refer to before following the advice of any social media page. All in all, an SPC 4/5 not verifying is a huge blessing as widespread damage is nothing anyone wants. Although I am hearing some eye-witness account of a possible quick spin up in the London Bridge area that caused localized damage such as several snapped trees and some structural damage.

Failure mode wins here. Makes total sense too, no cap means everything will loosely rise, limits lapse rates, and paired with the the water bogged moisture profile, today’s crapvection actually saved us from a much more impactful scenario, keep a watchful eye throughout the evening!

📈⛈️🌪️Looking at the the 00z Nam and HRRR, both show a window from 4pm-7pm where the surface low in NW VA seems to bottom out in the mid 990’s ahead of the first of potentially 2 QLCS systems.

If modeled correctly, this would be the bulk of our tornado threat as both CAPE, and wind shear will be maximized around this time. If the low were to come together, it would enhance our surface winds just enough out of the S/SSE for potentially multiple quick spin ups.

Most CAM’s have been actually downtrending on the widespread discrete supercell threat that was really driving this risk to the moderate level. However, I don’t buy this as a solution, if anything it just adds to the uncertainty. Even if correct, the widespread wind impact tomorrow will still cause plentiful damage. Will be interesting to see how this afternoon plays out.

🚨⏰ We are just about 12-14 hours from nowcasting potential dangerous to life-threatening severe weather tomorrow. The tornado threat looks maximized still from I-95 East to Suffolk, however, the reality is that with a developing surface low, winds could become backed over a wider region very quickly, keeping the entire region under the gun.

What to expect: multiple rounds of strong to severe thunderstorms capable of all hazards beginning around 11:00 am. Storm mode initially could be a few widespread supercells before potentially becoming linear in the early afternoon. Then, a powerful QLCS as the cold front sweeps through in the evening, posing a severe wind risk as well as potentially a few embedded tornadoes.

A lot of this forecasting is hinging on the development of a surface low providing enhanced backed winds, as well as a bump in instability, if that surface low does not form, or the cold front pushes through quicker than the low can deepen as some CAM’s show, that would be best case scenario as the damaging severe threat would be mostly limited to strong winds, however, this is not the likely scenario currently.

Make sure you have a way to receive warnings, secure any loose items in your yard, or they are as good as gone regardless tomorrow once the QLCS pushes through, and make sure you have a plan for the worst scenario, such as finding yourself in a tornado warning tomorrow. Stay safe, Hampton Roads!

🚨Latest SPC outlook for day 3 attached below

Day three probabilistic outlook has now been bumped up to a 45% with CIG 1 intensity (New SPC feature added about 2 weeks ago demonstrating potential intensity of severe impacts such as wind, hail, and tornado potential).

I must say it’s been some time since Hampton Roads has been this close to the bullseye for severe weather, we typically see 1, maybe 2 outlooks like this a year. I would not be at all surprised to see a Moderate (4/5) go up next out look for areas between I-95 East to Suffolk.

Like any severe weather scenario, the days leading up and adjacent posts are not meant to spread fear/panic but to remind you to stay weather aware, and make sure you have multiple ways to receive warnings.

🚨💨🌪️Latest SPC outlook regarding our Severe Threat in Hampton Roads on Monday 3/16

The SPC has gone with a day 3 Enhanced risk (3/5) Keynotes being, hail, damaging winds, and a few tornadoes possible with the most likely timeframe for severe potential being in the afternoon, through the evening as the cold front moves through.

As I stated earlier, thermodynamics and kinematics are there, some disagreement on the speed of the cold front remains, however many models show the cold front moving through in the evening still, meaning that day time heating and the deepening low may synchronize for a robust supercell threat. On the contrary, some models show a faster cold front which would minimize our severe risk as not much destabilization ahead of it will take place, however this is currently the more unlikely scenario.

“Depending on the degree of destabilization, a strong
tornado or two may occur especially over parts of the Carolinas and Virginia during the late afternoon”

🚨⛈️🌪️ Rare Severe Weather Setup Likely Monday
The SPC has issued a Day 4, 30% chance of severe weather for Monday for our area along and east of I-95, with a specific mention of “a few tornadoes possible.” This will likely lead to a "Slight" or possibly "Enhanced" risk once we get within the 3-day outlook range.

This is a rare event for us here in coastal Virginia; it isn’t often that we see supportive thermodynamics and kinematics align over our region at the same time.
What does this mean? Ahead of a strong line of thunderstorms (QLCS event) on Monday, any storms that root to the surface will have ample shear to organize into supercells, creating a potential tornado threat. The hodograph below shows a broad area of inflow which—when paired with shear, low-to-modest CAPE, and decent lapse rates—makes this threat very real.

The shear profile alone is more than enough for this to be a realistic possibility. Additionally, the LCL/LFC heights in the low levels indicate that any cell formation should be surface rooted with enough shear to support robust, spinning thunderstorms. Even after the initial cells pass, a tornado threat remains as the QLCS moves through, potentially producing multiple quick, "spin-up" tornadoes.

Stay tuned to the SPC and local updates!
