Poor weather conditions could ruin a clear view of the total solar eclipse in parts of the United States on Monday afternoon.

The path of totality, when the moon fully blocks the sun, will occur along a 100-mile-wide stretch from Texas to Maine, giving people in Dallas, Indianapolis, Cleveland and Buffalo, N.Y., prime seats. It will be the last total eclipse over the United States for 20 years.

But some of the southern areas, including Texas, could face clouds or storms. NOAA's Storm Prediction Center puts Dallas on a very high risk of thunderstorms.

San Antonio, Austin and Waco also face a threat of storms on Monday afternoon.

The National Weather Service says northern New England remains the best location for clear viewing of the total solar eclipse on Monday afternoon.

Southern Texas is expected to have fair conditions in the morning, but will likely see a rapid untimely increase of clouds into the afternoon, prior to the arrival of the solar eclipse.

Best place to watch total solar eclipse

Northern New England appears to be the best bet for a clear view.

That region is where cloud cover will likely be minimized along the path of totality, as a swirling nor'easter moves farther out into the Atlantic.

It appears that other locations in between will have a fair chance of cloud cover at various levels, although locations across Arkansas to the Midwest could see breaks in the clouds or high thin clouds during the time of totality.
