  1. If I had to guess our horrible lapse rates are doing something. We are sitting around 5.5 ml lapse rates which nearly puts us to a stable atmosphere.
  2. 3k NAM has a neat cyclonic feature near Kentucky that lasts all Sunday.
  3. That MD cell has some storm rotation. Not tight or anything but I’m sure someone will get a nice storm picture of a sculpted base or something.
  4. 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!
  5. 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.
  6. Jokes aside aren’t we staring down a likely east based strong to very strong El Niño? I take climatology in the fall but my base teleconnections knowledge say that it won’t snow much.
  7. 35 degree 5 inch rainstorm is gonna go so crazy.
  8. Was looking at the models for tomorrow and I think we could be in for a surprise. The setup has 3000+ CAPE on both the NAM and the HRRR (maintains low 70s dewpoints). Additionally, there is a shortwave that nears our region to put us in divergence aloft from 4-6pm west to east. However, this shortwave also appears to draw in a time sensitive increase in our 0-6 shear to 20-30 knots, while that still isn't good for severe storms it opens the door to having some level of organization. To add onto this factor is that the HRRR shows a small lee trough develop during the afternoon hours which causes a decently curved hodograph for the lower levels. To reiterate its nothing insane, but might be a sneaky day for supercellular storms to form and rotate. The HRRR and NAM both show storm relative helicity values for 0-3km of around 100 as well. Typical mid-atl caveats apply (our ML lapse rates suck) and I'm not saying this will be some crazy day, but just that it shouldn't be slept on. @vortex95 would love to know your/any other mets/wannabe mets thoughts. Below is the HRRR and NAM sounding, can see the difference the lee trough makes with the HRRR having that curved hodograph.
  9. Man I should write to my VA state house rep to ask if they could ever make a program like this for my state.
  10. A question I’ve wondered about for a while is if our area always benefits from emls. The tor threat way back in March had a weak one and it kneecapped our cape. It seems that sometimes that temperature increase (or slower rate of decrease) does more harm than it helps.
  11. Under the stratiform rain coming off the cells in southern Fairfax and still get .2+ inch per hour rates.
  12. I think a fun bit of micro climatology played a part in that storm complex. Looking back at radar shows the storm popped up right over Dulles airport around 9pm. In college I learned that the delayed heat release of pavement peaks ~2 hours after the inversion layer sets. Definitely think that the local heat island of Dulles helped make a convective current that finally broke into our high CAPE environment. Now we get to watch the storm spread out through boundaries. Really goes to show how human made heat islands impact the whole area around them.
  13. Was coaching for the IM-meet which is a mile from Dulles and that storm is a crazy lightning producer. Tons of CG strikes with loud thunder.
