WASHINGTON (WUSA9) -- Here are five things you need to know on Tuesday, April 15:
5. After a beautiful weekend, get ready for heavy rain and plummeting temperatures. We'll see showers Tuesday morning with pockets of heavy rain later in the day. Storms are possible as a cold front moves through and we'll have much colder Tuesday night and Wednesday.
4. Tuesday, April 15, is the deadline for taxpayers to file their 2013 returns, but unless you expect to owe the government money, you have all the time in the world. "If you have a refund coming, there's actually no penalty for filing after April 15," said Stanley Veliotis, associate professor at the Fordham University School of Business.
3. When hundreds of survivors and first responders gather Tuesday in Boston, there will be tears. But there also will be much to celebrate. A city's resilience. The courage of so many. The strength of those who lost limbs and loved ones. Three people were killed and more than 250 injured in the twin April 15, 2013, blasts. Dzhokhar Tsarnaev's trial is set for November.
2. A Tyrannosaurus rex skeleton is arriving at The National Museum of Natural History. Officials say the skeleton will make its way from Montana to Washington on April 15 to be featured in the museum's new 31,000-square-foot national fossil hall. The hall will open in 2019. The current hall will be closed on April 28 for renovations.
1. A simple noise complaint has lead to a police stand-off at a Tysons Corner apartment complex, forcing several residents from their homes. When officers spoke to a man who was accused of playing loud music, he threatened to shoot them if they came inside.
