Summer today, spring tomorrow. Temperatures jumped above 80 degrees today for only the third time this month. That warmth is short-lived, though, as a backdoor cold front sweeps through the region tonight, possibly triggering a few stray showers. But it mostly ensures we stay cloudy and cool on Sunday.
