Well, here in the Central California it's really hot. That's mostly why I'm typing right now instead of doing something constructive.

In as little as 1 1/2 you can be in San Fransisco,Santa Cruz etc and feel a 40 degree temperature drop. I know in a relatively short distance you can get from cold to really freaking cold, but since it's summer, maybe keep it to heat related locations. I don't know much about states outside of California, so enlighten me on some of the biggest temperature differences in the shortest distance between cities where you live or have been.

Phoenix, Arizona is one of the hottest cities in the country and you can drive to Flagstaff, Arizona in a little over 2 hours.
Flagstaff is one of the snowiest cities in the country while Phoenix RARELY ever gets snow.
The temperature difference is probably about 30 degrees, year round.

Well I live in a region with some tallish mountains. (Some would say 6000' is not a mountain)
Anyway, here in the southeast, elevation is the only way to get to a cooler place and every 1000' in elevation gain is roughly 4.5 degrees lower in temp. (Many factors but this is just a general idea)

So you can be driving along and one minute you're at 1500' elevation and it's 90 degrees and the next you're at 5500' elevation and it's 70 degrees.
In fact, just the other day I was on the blue ridge parkway in NC trying to escape the heat and literally went from 90-something to 68 then back up to 90+ all in the span of maybe 20 minutes including the time it took to get out and snap some photos.

Basically any place that is near any sort of abrupt terrain pattern will have microclimates. You can find localized microclimate conditions all over the Western United States because of all the dramatic terrain. Once you add the moderating influence of the ocean or even a larger body of water in in, you get crazy weather shifts in an extremely short distance because a large body of water needs a very specific temperature to heat up or cool down.

In Southern California, you get dramatic weather shifts. From Santa Monica to Palmdale, it is around 62 miles driving and a mere 45 miles as the crow flies. However, here are the average temperature of the some of the places along the way as the crow flies

SANTA MONICA PIER, CALIFORNIA - Climate Summary
CANOGA PARK PIERCE COLL, CALIFORNIA - Climate Summary
MOUNT BALDY NOTCH, CALIFORNIA - Climate Summary
PALMDALE, CALIFORNIA - Climate Summary

Santa Monica Pier (on the coast)
Jan: 64.1/49.2
Jul: 71.0/61.2
Precipitation/year: 12.63 in/yr
Snowfall: 0

Canoga Park (in San Fernando Valley)
Jan: 67.9/39.3
Jul: 94.9/57.0
Precipitation/year: 16.86 in/yr
Snowfall: 0

Mount Baldy (though out of the way, only station in the mountains that has enough data)
Jan: 42.7/26.4
Jul: 75.3/53.2
Precipitation/year: 40.36 in/yr
Snowfall: 131.3 in/yr

Palmdale (in the Mojave Desert)
Jan: 58.5/32.4
Jul: 97.6/65.3
Precipitation: 7.62 in/yr
Snowfall: 1.4 in/yr

Hence, you get weather forecasts in SoCal that contain High Desert, Low Desert, Valleys, Coast, Basin.

I have been to what is generally regarded as the greatest elevation change in the shortest distance in the world. Mt Haleakala on the Island of Maui, rises to 9,740 ft from sea level on it's southern flank just 5 miles away. The temperature swing from the summit at sunrise where temps dip below 40 degrees to the coast can vary by as much as 30 to 40 degrees. Driving to the summit from the coast will take up to 2 hours and require almost 50 miles of driving. All things considered, I would have rather stayed at the hotel and downed a few more Mai Tais.
