6-Day Temperature Outlook Minor HeatRisk 6-10 CPC Outlook First 90° Day Stats
The average first 90° for all three of our climate sites occurs in mid to late March. However, the earliest 90° for all of the climate sites has already passed. So even though we're forecasting for all three sites to reach 90°+ by the end of the week it won't be the earliest occurrence.
