The Earth will pass between the Sun and Moon early Monday morning creating a partial penumbral eclipse. Penumbral because the Moon will be passing through the lighter penumbral shadow. Partial because a small part of the Moon will be outside that shadow.
The eclipse begins at 2:32 am and ends as dawn is breaking at 6:53 am. It will be at its greatest around 4:44 am.
Penumbral eclipses like this one aren't as spectacular as those where the Moon passes through the darker umbral shadow. Also overnight clouds will make seen the eclipse difficult. But if you are up and catch a glimpse of the Moon through breaks in the clouds, you may notice a slightly redder color.
That color comes from the way our atmosphere scatters shorter wavelengths of light (like blue) leaving longer wavelengths (like oranges and reds) to pass through and be cast onto the lunar surface.
