July 1-8, 2012 Heat & Storms

Recommended Posts

AREAS AFFECTED...CNTRL/SCNTRL PA...NRN MD  

 

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE  

 

VALID 052037Z - 052230Z  

 

PROBABILITY OF WATCH ISSUANCE...40 PERCENT  

 

SUMMARY...THUNDERSTORM DEVELOPMENT EXPECTED NEXT 1 TO 2 HOURS IN  

CNTRL PA. DAMAGING WIND SHOULD BE MAIN THREAT INTO LATE AFTERNOON  

WITH ISOLATED LARGE HAIL.  

 

DISCUSSION...ALTHOUGH SFC WINDS ARE W/NWLY...TEMPERATURE HAVE  

CLIMBED INTO THE MID 90S AND DEWPOINTS ARE IN THE UPPER 60S TO NEAR  

70. MLCAPE IS IN EXCESS OF 3000 J/KG. MODEL FORECASTS THE CAPPING  

INVERSION OVER THE AREA SHOULD CONTINUE TO WEAKEN ALLOWING STORMS TO  

DEVELOP. SATELLITE ALSO INDICATES CU FIELD IS BECOMING MORE  

ENHANCED ON VIS IMAGERY. DAMAGING WINDS AND ISOLATED LARGE HAIL  

COULD BE POSSIBLE ONCE THE STORMS FORM AND A WATCH IS POSSIBLE.

Question for you severe guys. My knowledge is pretty weak but I'm slowly catching on. I was wondering about organized convection in our area and where it initiates. Do we ever get medium to large sized convective systems that originate east of the apps or do all the bigger ones start in the oh valley / midwest first?

Also, unless my memory is getting crappy (and it might be), why does is seem that we get fewer squall lines than we used to? My memory of the 80's seems to remember that it was common to get large lines of storms (stretching from s pa all the way to central va?). Not front related stuff either. Just hot afternoon events. Now it seems like random popcorn seems more common. It might have always been this way. I'm not sure.

Boo-urns.

Us "DCists" should undoubtedly meet up more often than once a year. SNE puts us to shame.

Sorry, I'll definitely be there Saturday. So if you don't gotta help Pops out, I best be seeing you.

I'm not sure how to quantify it but I think the majority of our storms come from the pre-frontal/leeside trough. Though as far as our big MCS+, they probably more often come from west/northwest of the Apps as stuff on the trough doesn't often have enough time to form up in a huge way for most of us. Every now and then we'll get a good line out of the SW too.

For the most part, I would quantify a med-large event as one where over 80% of the area is affected. Not just hit and miss blobs.

I know there are a zillion variables though so it's really tough to answer my question without having really go into detail.

I grew up boating on the Chesapeake almost every weekend from May-Nov. We got caught in alot of tough weather. Many of the lines that came through affected the entire bay. Narrow but long lines of storms. Plenty of wind with them. For the most part, they looked the same while approaching. Really dark line in front with orange or green sky behind. I just don't see that very often anymore. I could be totally off base but it seems like it was more common than it is now. Just like overrunning snow...lol

Maybe somebody can explain the meteorology of it, but I don't remember us getting too many areas of rain and storms like the blob that moved through WV and swVA today. Not only slow moving but also solid, large area of heavy rain.

this has been a really stormy week or so for good chunks of the eastern half of the country.. almost exceptionally so. swva in particular seems to get hit every day lately.
