The Fourth of July is a day usually reserved for parades, cookouts and fireworks, but the weather doesn't always cooperate.

Rain showers and thunderstorms — and even a lack there-of — are putting a damper on some celebrations across the U.S.

The heaviest rain on the actual holiday are most likely across the Ohio Valley, stretching across southern Illinois, southern Indiana, southern Ohio, West Virginia and Kentucky.

All of this rain is because of a stationary front setting up shot across the region, and depending on the timing of these rain showers and thunderstorms, it could postpone or cancel some fireworks in those states.

At the other side of the spectrum, some cities in the western United States and a few places in the Midwest have banned fireworks because of drought and increased fire risk.

Pop-up thunderstorms in the eastern half of the country and drier conditions across most of the West are fairly common for early July.
