Temperatures will rise steadily over the next several days, starting with highs of 86 today, 93 tomorrow, and 98 on Friday, then break the 100-degree mark for the first time this year on Saturday. If Monday sees 103 and Tuesday 104 as predicted, both will set new high-temperature records and could lead to Extreme Heat Watches and/or Warnings, as the highs are 10-20 degrees above normal for this early in May.
