The states that Obama won over the weekend had a total of 185 pledged delegates. Tomorrow's primary states have 168. That's a total of 353 delegates. Ohio and Texas, meanwhile, combine for 224 delegates. (That's my back of the envelope calculation from the numbers at wikipedia.)
And Obama won enormous blowout victories over the weekend, and is up by double digits Tuesday. So even if Clinton wins Texas and Ohio, it will be impossible for her to make up just the delegate advantage Obama has won and should win over these few days.
