The product label for Celsius WG does state: For maximum weed control with broadcast applications, add non-ionic surfactant (NIS) at recommended rate to the spray solution. For difficult-to-control weeds, add methylated seed oil (MSO) at a rate of 0.5-1% v/v to the spray solution.
As long as the temperature during the application of the Celsius WG Herbicide is not 85 degrees or above, then it does not matter what temperature it reaches mid day. The best time to apply herbicides is either early morning when dew is still fresh on the ground or late afternoon when the lawn and weeds are under less stress from the environment. Temperatures over 85 degrees will cause extra stress on your desirable turf, possibly causing damage.
Celsius WG Herbicide should not be kept in the refridgerator, it should be kept in a cool dry place out of direct sunlight.

As with most herbicides the exact volume of water is not very important, you just need to be sure you are getting the correct amount of product on a specific area. Celsius may be applied at three different rates depending on the weeds to be controlled. For the appropriate rate and species consult USE RATES FOR WEED CONTROL section on the Celsius product label. For spot applications, add the specified product rate of 0.057-0.113 oz (1.6-3.2g) to enough water to create approximately 1 gallon spray solution. One gallon of spray solution will treat up to 1,000 sq ft. For maximum weed control with broadcast applications, add non-ionic surfactant.

Celsius WG Herbicide is not labeled for eradication of Poa Annua. Depending on your lawn type Certainty would be a better option.
Celsius WG Herbicide is a selective herbicide with multiple modes of action that provide a broad spectrum of weed control. Celsius WG Herbicide controls weeds after they have germinated (post) and also has some residual activity that prevents new weed germination, depending on the specific weed. Per the product label: Weed growth ceases within hours after application. Symptoms progress from yellowing to necrosis resulting in plant death within 1-4 weeks after application. The speed of symptom development varies with temperature and will be faster at warmer temperatures. Two of the three active ingredients in Celsius WG Herbicide (thiencarbazone-methyl and iodosulfuron-methyl-sodium) inhibit acetolactate synthase (ALS). ALS is responsible for the synthesis of essential amino acids that are essential for plant growth. Inhibition of these amino acids stops weed growth. Celsius WG Herbicide also contains dicamba, a benzoic acid herbicide that acts on the same biochemical site as the natural plant auxin, indole acetic acid (IAA)
