Winds are being shown as close to 80 mph

on the BWI radar in Queen Anne's county.

A good thing not much is out there beyond

the Centreville area.

Yeah you're right, both of the warnings on the storm have enhanced wording as well. Here is one of the warnings:

Tomorrow def should be more widespread tho today ended up meeting potential generally I think.. DC got kinda screwed but that always happens. If you take Arthur away the 500mb pattern is pretty solid tomorrow. Arthur should add some oomph to the front but not sure if it will be big storms or just big rain.

 

Damaging winds look like primary threat.. don't see any tor risk, esp with hodos being straight lines and no real SRH

Day 1 0600z OTLK is out..  15% hail/15% wind/2% tor

 


..MID-ATLANTIC INTO NEW ENGLAND    RICH BOUNDARY LAYER MOISTURE WILL BE IN PLACE ACROSS THE REGION WITH  SFC DEW POINTS FROM THE UPPER 60S TO LOW 70S ALONG MUCH OF THE  EASTERN SEABOARD. WHILE MIDLEVEL LAPSE RATES ARE EXPECTED TO BE  RATHER POOR /LESS THAN 6.5 DEG C PER KM/...POCKETS OF STRONG SFC  HEATING SHOULD RESULT IN WEAK TO MODERATE INSTABILITY BY MIDDAY  GIVEN THE DEGREE OF BOUNDARY LAYER MOISTURE. THE COLD FRONT AND  NEARLY UNIDIRECTIONAL DEEP-LAYER SHEAR PROFILES WILL TEND TO FAVOR  STORM CLUSTERS OR BROKEN LINES...BUT 30-40 KT OF DEEP-LAYER SHEAR  MAY ALLOW FOR BRIEF SUPERCELL STRUCTURES EARLY IN STORM EVOLUTION.  DAMAGING WINDS WILL BE THE MAIN THREAT...AS AFOREMENTIONED POOR  LAPSE RATES WILL LIMIT LARGE-HAIL POTENTIAL...BUT SOME MARGINALLY  SEVERE HAIL IS POSSIBLE IN STRONGER STORMS.

With todays storms you either got totally annihilated or you got meh. Woodbridge VA got meh. Generally speaking Maryland is a major winnah, both in terms of winter snows and in terms of big storms and rainfall in summer.

 

I need to move to maryland pronto. Otherwise I'll learn to embrace a meh life.

 

Overall, I expect northern Virginia to be drier than normal through late September with an overall warmer than normal July and August and at or 1 degree above normal September. After that, all depends on the Nino - if it develops at all.

Get used to walkin on crackly grass with dust. We will be doing it for the next 11 weeks at least.

 

Ugh! I hate summer with a vengeance. This weather really sucks huge hairy goat balls.

Local models seem to want a train of storms this afternoon... looks good to me.  Severe will be a bonus IMO

Yeah, slow movement etc been a signal for today a while. Could be a good lightning day if there's not 1/8 mi vis rain in the bands.

I could see a damaging wind threat with the hodos... but I don't see a TOR risk.  SRH doesn't really support it... though I guess its non-zero.

LOL, did I hear that corretly on CNN just now?  DC moved their fireworks up to tonight?  WHY the hell would they do that, weather will be worse tonigh than tomorrow.

 

There is a story up on WTOP that they are worried about the stuff that is already set up being blown down, but nothing about moving the whole thing up.
