Two Severe Thunderstorm Watches; Air Travel Mess

By -
Here are the two severe thunderstorm watches (primary threat = damaging winds) in effect until 8pm EDT.

There are already significant or major delays at O'Hare, Newark, JFK, LaGuardia, Philadelphia, and San Francisco (due to low clouds and fog). There were earlier significant delays at Minneapolis and Detroit and may still be reverberating because of those delays.

Additional delays are likely.

Here is the AccuWeather Regional Radar form 12:50pm EDT. More thunderstorms are developing at this time.

A couple of tornadoes, hail and wind gusts to 65 mph are possible with these storms. This includes NYC and Philadelphia.  1:05pm. The tornado risk has been extended northward into New York. The brown area has a significant risk of tornadoes. Remember: if a tornado warning is issued, go to your basement and get under heavy furniture like a pool table. Of, if your basement is finished, get into the bathroom. Go ahead an put a couple of water bottles and, if appropriate, diapers in your shelter area.

Children should be put in the bathtub.  I'll update later today.

Pink is a winter storm warning for significant icing. Deep green is a winter storm watch. I don't know why this is still a watch.
