Weather extremes
How extreme does Mission's weather get?
The hottest, coldest, wettest and snowiest days Mission has recorded — the outer limits of what its weather can do, and how far they sit beyond a normal day.
The four kinds of extreme
The hottest, coldest, wettest and snowiest single days Mission has recorded — each shown against what a normal day that time of year looks like.
That is about 37°F hotter than a normal June afternoon in Mission (typical high near 70°F).
The three most extreme on record
About 29°F colder than a normal December night in Mission (typical low near 32°F).
The three most extreme on record
About 81% of a typical October's rain in a single day (Mission averages roughly 6.7 in across the month).

How hot and cold it gets, month by month
The shaded band is the normal range of daily temperatures for each month. The dots show the most extreme it has ever been — so you can see how far beyond a normal day the records really sit.
Mission's record heat sits well above even a hot day for the season — June's 107°F is about 37°F beyond a normal hot afternoon. Its record cold is just as far below a normal winter night — the dots mark how rare each extreme really is.
