If you were hoping to get the perfect Instagram photo of Manhattanhenge this week, the weather may ruin your plans.
Manhattanhenge -- the alignment of the sunset with Manhattan's grid, a sight that's inspired photographers and Instagrammers from near and far -- happens on four days each year, according to the American Museum of Natural History.
The full sun is slated to align with the grid at 8:20 p.m. on Wednesday, July 12, and half the sun will align at 8:21 p.m. on Thursday, July 13. But a 40 to 50 percent chance of thunderstorms on Wednesday and a 30 percent chance on Thursday could ruin your view of the sunset.
Cloudy skies also blocked the sun when it aligned on May 29 and 30.
If the storms hold off, New Yorkers can see Manhattanhenge at major streets like 14th, 23rd, 34th, 42nd and 57th streets. The American Museum of Natural History recommends standing on the east side, but keeping a clear view of the west so you can still see New Jersey.
Plan to get to your viewing spot about a half hour before the sun is expected to align.
