Although there are some heat-tolerant varieties, tomatoes in general do not like temperatures over 90F. They may drop flowers or have other pollination/fruiting problems. It helps to relieve the stress of the plant by providing some shade during the hottest part of the day, such as with shade cloth. It is good that you have kept up with the watering—they need extra water to help them survive the heat. However, it is very important that the water is draining properly, or it will encourage rot. Avoid high-nitrogen fertilizer. Picking fruit can also help the plant redirect its energies to maintaining itself. Heat stress can make the plants more susceptible to disease, signs of which can sometimes be wilting. Check for spots on the leaves, discoloration within the stem, etc. If it is not a disease, it is possible that your plant might recover for a fall crop, but it is hard to predict. Good luck!
