The main player in our weather over the next 5-7 days of weather will be a large, cool dome of high pressure slowly drifting southeast out of the Ontario region. With it comes a large modified, Canadian airmass that will bring a spectacular feel to the air, shoving the high humidity values well south. With the approach of the Canadian High pressure comes a northwesterly wind, advecting cool autumn-like weather into the region.

Weather in the DC area can be summed up fairly quickly with highs near 80 and lows dipping into the upper 60s to near 70 pretty much through next week! There will likely be very little worth-while to talk about weather wise in the Mid Atlantic region for the next few days as the high slowly creeps along to the east.

Yet another Tropical Storm forms in the central Atlantic Ocean the 13th named storm of the season (Maria), and we've barely started September. This month is climatologically the most active portion of the Atlantic Hurricane Season with 2-5 named systems developing within the month. Maria doesn't look all that great on satellite with sporadic bursts of convection around its assumed center of circulation.


Don't expect Maria to be any threat to land, with the only impacts being to mariners in the central Atlantic Ocean.

Relief efforts finally showing up in New Orleans after being all but absent from the city for the past 4 days. Some are thinking this may be too little, too late for the devastated community of Louisiana, but at least help is there.


The National Guard and other Agencies like FEMA have been pouring into the city through the evening hours beginning what will be an excruciatingly long and tiring recovery process.
