Lots of interesting facts. I didn't know Tampa ranked so high when it comes to pollen. That explains my allergies!

Worst cities for allergies
Based on pollen counts from 1999-20002
3. Tampa/St. Pete, Florida

Small sample though.

We be warm here in Tampa...

10 hottest cities
Average annual temperature, F
10. Tampa, Florida  72.0

And mother nature loves to provide fireworks...

Top 10 Thunderstorm cities
Avg annual number of thunderstorms
2. Tampa, Florida  87

But this one surprised me...

Top 10 Tornado  states
Avg number of tornadoes per 10,000 square miles, occurring from 1953-2004
1. Florida  9.4

Perhaps that is skewed by weak tornadoes in landfalling tropical systems. We certainly don't see the strongest of course.

At first I though it was odd that some of the most humid places were in Washington until I remembered how rainy it usually is.
Quillayute, Washington, rains, 210 days a year and is the most humid and has the second most cloud cover. I'd take that compared to the dry heat of Vegas though.

And while I had seen some of the fastest warmings before, the cold ones, yikes:

Fastest Cooling
24 hour chill:  100 degrees. From 44 to -54 below zero in Browning, Montana on January 23-24, 1916.
12 hour chill:  84 degrees. From 63 to -21 below zero in Fairfield, Montana on December 24, 1924.
2 hour chill:  62 degrees. From 49 at 6:00am to -13 at 8:00am in Rapid City, South Dakota on January 10, 1911
15 minute chill:  47 degrees. From 55 at 7:00am to 8 at 7:15am in Rapid City, South Dakota on January 10, 1911

I usually leave the jacket at home when the temp is above 53 degrees. If I ever visit Rapid City, I'll have to rethink that or keep a good eye on the weather.

Some of the other facts I found interesting:

The longest rain-free period in the United States was 767 days (2 years, 37 days), from October 3, 1912 to November 8, 1914 at Bagdad, California.

A world record rainfall occurred at Holt, Missouri on June 22, 1947 when it rained 12 inches in just 42 minutes. This averages to over 1/4 of an inch of rainfall per minute. On July 4th, 1956 In Unionville, Maryland 1.23 inches of rain fell in 1 minute.

Is Chicago really "The Windy City?"  Of the 262 major weather reporting stations in the United States, 27% or 72 stations average higher annual wind speeds than Chicago, which averages 10.3 mph. For example, New York City's annual wind speed is 12.2 mph.

Due to Florida's proximity to the equator, the state receives more than a hundred times the UV exposure that Maine does.
I'm never going outside again, lol.
