The cold front responsible for ending our heat wave stalled out close enough to keep us socked in with clouds much of the day, though we are seeing a few breaks this afternoon. Highs are reaching mainly into the mid-80s with an upper 80 or two. Still warm and humid, but not too bad compared to recent days. Many spots have stayed dry with just a few showers making it in so far. As we head into evening, more showers and storms are possible.

Through Tonight: Showers or storms -- a few possibly strong -- should be most numerous in the evening (mainly between 6 and 11 p.m.), but I can't rule out a passing shower through the overnight. Evening readings dropping through the 80s should bottom out in the upper 60s and lower 70s.

Tomorrow (Thursday): An upper-level system should slowly track along the front to our south and this may give us a period or periods of rain showers through much of the day - starting in the morning and tapering during the afternoon or evening. We'll cool it down another notch on Thursday as highs range from 80 to 85 across the area.

Warm July Globally: AccuWeather's Brett Anderson examines NASA's Goddard Institute of Space Studies determination that July 2009 was the second warmest on record. The global anomaly was +.6C (+1.08F), ranking only behind the strong El Nino year of 1998. One of the few "cool spots" happened to be across the northeast U.S., but warm areas far outnumbered the chilly ones.

The NWS has upped the second tropical wave off of Africa's potential for development from low (>30%) to medium (30%-50%)!

Areas north AND south of us are getting some decent precipitation, except us. Will be a shame with all this cloud and stalling front for nothing. Last August we had 1 in. we may get less this August the way it's going.

Is there a storm moving in on us from the northwest?

No 90s at the Big Boys, perhaps, but some of the robo-observers were telling a different tale:
Baltimore/Martin Airport was reporting 90 at 4:45, and College Park was likewise at 3:50. Leesburg started the party at 3:20.

Will the DC area be able to view the Perseids meteor shower this year?? If so, when and where's the best place to see it?(Thanks google!)

Some friends saw a few through light cloud cover here in Rockville last night/this morning. I didn't see any. :'(

Another rainless evening in Montgomery County. Things looked so promising earlier.

CapitalClimate, I don't know as much about College Park (which seems OK usually), and Baltimore/Martin is technically outside our area I believe, but Leesburg (KJYO) is almost always a warm outlier which draws it into question as a reliable source in my opinion.

Sorry, I didn't get the memo that says Gangsta opinion is more accurate than everyone else's data.

I'm pretty sure the thoughts on JYO are fairly widespread, on some days it is almost funny the difference between the temperature there and personal stations surrounding it -- and I don't necessarily discount the College Park number, had not seen it. Automatic stations are more questionable as a whole than ones that are manned... maybe why they are not kept in the official NWS records. Either way, I guess I should have known better than to try to have a real conversation with you here.
