[Widespread area of eyewitness accounts from last night's meteor according to the American Meteor Society]

Discussion

A very bright meteor was seen streaking across the skies throughout the Mid-Atlantic region on Sunday night according to dozens and dozens of eyewitnesses. The fireball flashed over the Mid-Atlantic region around 11pm according to numerous reports and turned night into day for a few seconds as captured on video in State College, PA. The American Meteor Society (AMS) tracks fireballs and they have received more than 150 reports from Virginia to New Hampshire and as far west as central Ohio (Google map above shows range of reports; Google map available at http://www.amsmeteors.org/fireball_event/2014/2187; courtesy AMS). The meteor was so bright in fact that numerous reports have poured in from the highly populated areas of DC, Philly and New York City. Jesse Ferrell of Accu Weather (State College, PA) recorded video on “dropcam” webcams in State College, PA and posted this to YouTube (http://youtu.be/Q3Mu5bFKjHY) which captures the lighting up of the sky as the meteor passed overhead.

Discussion

The coolest air mass of the season so far has dropped early morning temperatures into the lower 50's across many suburban locations and afternoon highs will stay at below-normal levels for this time of year despite plenty of sunshine. High pressure controls our weather today, but a weak cool front could generate shower activity in the region late tonight and early tomorrow before high pressure regains control and dry, cool weather returns to the area.

Discussion

A strong cool front passed through the region late yesterday ushering in a chilly air mass for this time of year that had its origins in western Canada. As a result, the Mid-Atlantic region will feature below normal temperatures not only through the weekend, but also through the early and middle parts of next week. This early season Canadian cold air outbreak has had its biggest impact relative-to-normal across the northern Plains and northern Rockies where snow has accompanied the plunge in temperatures. Some spots such as in Rapid City, South Dakota have seen their earliest snowfall on record and nearly a foot of snow has fallen in higher elevation localities across the northern Rockies. High pressure centered over the middle of the country this morning will extend into the Northeast US protecting us from any rainfall, but a disturbance to our southwest will produce occasional rain around here on Saturday. The combination of the entrenched chilly air mass and thick clouds on Saturday will make it a struggle for temperatures to surpass the 70 degree mark - way below the seasonal norms for this time of year. While some sunshine will return on Sunday and Monday, temperatures will stay at below normal levels as mid-September approaches.

An update on the recent solar activity...the first of two CMEs expected to hit Earth's magnetic field on Sept. 12th has indeed arrived, and a minor (G1-class) geomagnetic storm is underway as a result of the impact. The second and potentially more powerful CME is still en route. NOAA forecasters say geomagnetic storming could become strong (G3-class) during the late hours of Sept. 12th and Sept 13th after the second CME arrives.

Discussion

A strong cool front will approach the region later today generating scattered showers and thunderstorms during the afternoon and evening hours. Temperatures ahead of the front will climb to the highest levels of the week and the humidity will become quite noticeable by this afternoon. The cool frontal system passes through the area by early tomorrow ushering in another cool air mass just in time for the weekend. In fact, temperatures will hold at below normal levels on both weekend days and there is likely to be occasional rain on Saturday in much of the Mid-Atlantic region adding to the chill in the air.
