95 to 106 are acceptable values
95.0 and 106.0 are valid inputs along with all floats within range
95 and 106.0 are also valid inputs

Regular Expressions aren't the right tool for this. https://stackoverflow.com/a/1377937/1247512 answers a similar question thoughtfully. — David, May 07 '20 at 01:54
@rebusB, allowing floats as well as integers complicates things, depending on the amount of verification desired (rejecting `101.1.3`, for example). — Cary Swoveland, May 07 '20 at 04:25

Assuming that temperatures are representations of integers or floats having a digit after the decimal point, you could use the following regular expression.

Demo

The regex engine engine performs the following operations.

\b             match a word break
(?<!\.)        the following character is not preceded by '.'
(?:            begin a non-capture group
  (?:          begin a non-capture group
    9[5-9]     match '9' followed by '5', '6', '7', '8' or '9'
    |          or
    10[0-5]    match '10' followed by '0', '1', '2', '3', '4' or '5'
  )            end a non-capture group
  (?:\.\d)?    optionally match a decimal and one digit
  |            or
  106          match '106'
  (\.0)?       optionally match '.0'
)              end non-capture group
(?!\.)         the previous character is not to be followed by '.'
\b             match a word break
