Intro:

This is the very first Sudoku puzzle I set, I hope you like it :)

Rules:

#1 Normal sudoku rules apply.
#2 Normal thermometer rules apply: Along thermometers digits must strictly increase from the bulb end.

#3 Hailstorm: Each blue square represents a hail chunk. All chunks fall straight down in the column in which they appear (re: they do not move into other columns) and reach row 9 after a whole number of seconds. The digits in the first cell below and to the right of a chunk give the speed (in blocks per second) at which it falls and time (in seconds) it will continute falling before reaching row 9. These two digits may appear in either order.

For example a chunk appearing in R8C3 would cause both R8C4 and R9C3 to contain the digit 1. This would mean that the chunk would move downward for 1 second at 1 block per second and successfully reach row 9 after a whole number of seconds had passed.
