Here in Houston, Texas, we've had tomato blossoms for about 3 weeks,
now.. but no tomatoes.
Maybe it's too-early in the season? However, this is a big change for
the better compared to last year -
when the days were so hot the blossoms would drop about a two or two
after opening!

Need night time temps above 55F and daytime temp under 90F.

You can improve their chances in a couple of simple ways.
1) If your tomatoes are caged, trellised or staked, grasp the cage,
trellis material or stake, and gently shake the plant. This can loosen
up clumping pollen and cause it to move around in/on the flower and
pollinate. This works best if you do it during cooler early morning
temperatures, or cooler evening temperatures, especially shortly after
sunrise or shortly before/after sunset. Doing this a couple of times a
day really does help improve fruit set. Some people will just reach out
and stroke their plants, like they were petting a cat.

I looked at your weather, and, presently, it looks ideal in Houston. So
that doesn't seem to be your problem.

2.) If your temperatures are on the borderline of those that allow
pollination--max. temp. of about 92 to 95 and min. temp. lower than 75
(but higher than 55), shaking alone may not be enough but you can
improve the odds by "cooling" down the pollen and flowers with a brief
spray of water from the hose during the hottest part of the day (or
night). You don't want to hit the plant with such a hard stream of water
that the flowers fall off, obviously, though! Do this at least twice
daily when temperatures are right at the threshold of being "too hot"
and it can cool the flowers just enough that they will set fruit.
