Start with the place, day, period and units. Compare temperature and rain chance separately: the warmest period need not have the greatest chance of rain. A rain chance is for measurable rain at a point during the stated period, not a number of rainy minutes. A forecast is a prediction, not a record of what already happened.
Worked example
At a different practice place, Park Gate, the morning forecast is 9 C with a 10% rain chance and the afternoon is 15 C with 40%. Afternoon is warmer and has the higher chance there. Neither percentage says how many minutes rain will last.
Harbor Gate: An Invented Forecast for Monday
Morning (8 a.m.-noon): 16 C, 60% rain chance. Afternoon (noon-6 p.m.): 23 C, 30%. Evening (6 p.m.-midnight): 18 C, 80%. Each chance applies at Harbor Gate during its listed period. These are predictions, not observed temperatures or rain totals. Use current official local information and adult guidance for real weather decisions, not this practice table.
