Weather Risks In the Eclipse Zone: Now Until 3pm Monday

By -
Let's talk about the entire weather situation near and along the path of the eclipse tomorrow. 

Path of the eclipse pertinent to these forecasts.
There are going to be multiple hazards and given the reports of impromptu camping, etc., all of this becomes pertinent.

Severe Thunderstorms

Keep in mind that a "severe thunderstorm" is one with 1" or larger hail and/or wind gusts of 50 knots (which is 58 mph) or higher. The Storm Prediction Center uses a 5-level system for conveying these risks. 

For this afternoon and tonight, there is marginal chance (a 1 on the scale of 5) of severe thunderstorms in the dark green area.

Tomorrow -- the day of the eclipse -- the risk of severe thunderstorms increases. 
The yellow is a 2 on the scale of 5 with the darker green area still a 1. 

So, even though clouds are a problem, there is a safety issue with lightning, high winds and hail while caught in rural areas where there are few buildings for shelter. A car is adequate protection from lightning, high winds and hail (although the latter can ruin your windshield). If intense lightning is in the area, I recommend not touching the car's interior. 

And, there is yet another hazard. The NWS is forecasting a "slight" (level 2 on a 4 level scale) risk of flash flooding in the yellow area Monday.

Since so many people will be driving in unfamiliar areas, I highly recommend the AccuWeather app for your smartphone. When you install it, "allow" it to use location services. That way, it will follow you and provide storm warnings wherever you happen to be (provided there is a cell signal). 

I'll have a separate cloud forecast later this morning.

Midnight: The East Coast Threat for Tornadoes and Severe  Thunderstorms Has Ended 3:50pm. Tornado watch for the Middle Atlantic Region. 2:30pm Tornadoes are also forecast in the South. 2:20pm. 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. Wear shoes.  If you don't have a basement or safe room, go to the lowest floor and get into a bath or closet in the middle of your home. Children should be put in the bathtub.  I'll update later today.

Note: An Updated Forecast is Available HERE Freezing Rain The National Weather Service has now issued winter weather advisories, two warnings and a watch. It may be a bit too large but, when it comes to freezing rain and slick roads, caution is usually the better course of action.  Here's a color code: Deep purple is an ice storm warning; serious condition where power outages are possible. 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. If I were on the forecast desk I would have a winter storm warning for icing.  Dark blue is a winter weather advisory, a lesser condition, for icing.  Here is a view of the entire watch/warning/advisory area. The small area of green in Illinois is for flooding and, in Nebraska, for snow.  Here is a forecast of freezing rain amounts; totals to 6am Tuesday.  Color codes: Yellow is 0.25 to 0.50 inches. Power outages may occur in this areas. Deep blue i...
