Alan Abramowitz looks to November:
Democrats are in a stronger position to defend their majority in the House of Representatives today than they were in 1994 because a larger proportion of their seats are in strongly Democratic districts and they have fewer open seats to defend. However, if the national GOP tide turns out to be as strong this year as it was in 1994, Republicans would have a reasonable chance of regaining control of the House with a very narrow majority.
Chait's reflections on this here. It's still a long way off.
