My guess is either:
1) First Outlook will step in an hour early at 3AM ET, in the same format as the 4AM hour.
2) A reprise of the 12AM/2AM ET hour of EEWC will air, or
3) Rich and Sharon will give a live update at 3AM ET.
I'm aiming towards the third choice, though I wouldn't be suprised if long-form airs at 3AM.
