National Weather Service guidance shows a cold front arriving in Atlanta on April 5, poised to end a warm spell under high pressure and drop highs to near climatological norms of 69-73°F, aligning trader-implied probabilities heavily toward those bins at over 88% combined. Persistent ridging has driven above-normal temperatures into the low-to-mid 80s through April 4 amid isolated afternoon showers, but Sunday's front introduces cooler air masses, increased cloudiness, and 40-60% shower chances that cap peak heating. Model consensus from recent GFS and NAM runs supports this cooldown, though exact frontal timing introduces uncertainty—new evening updates could refine odds as resolution nears. Early April historical highs average 70°F, reinforcing the market's positioning.
