90° Facts

August 19, 2014

It’s been a cool summer with only a handful of locations hitting 90° or warmer. Take a look at these 90° weather facts:

Latest date for 90° or warmer to first be hit in a year:

  • Waterloo: 8/3/1958 (2014: 7/22)
  • Dubuque: 8/31/2001 (No 90s yet this year)
  • Cedar Rapids: 8/5/1979 (No 90s yet this year; data based on COOP observer)
  • Iowa City: 8/29/1951 (2014: 6/1; data based on Waste Water Treatment Plant)

# of years with no 90 or warmer days:

  • Waterloo: 0
  • Dubuque: 6 years (1915, 1979, 1992, 1993, 2004, 2008)
  • Cedar Rapids: 0

  • Waterloo: 21(1 this year)
  • Dubuque: 14 (none this year)
  • Cedar Rapids: 23 (none this year)
  • Iowa City: 27 (only once at the airport)

But we still have time to hit some 90s. We’ll have a chance this Thursday and Friday. Data does show that 90s have been hit as far back as October.

Is The Weather Difficult to Predict?

August 6, 2014

Consider a rotating spherical envelope of a
mixture of gases – occasionally murky and
always somewhat viscous.

          Place it around an astronomical object nearly
8,000 miles in diameter.

          Tilt the whole system back and forth with
respect to its source of heat and light.

          Freeze it at the poles of its axis of rotation
and intensely heat it in the middle.

          Cover most of the surface of the sphere with
a liquid that continually feeds moisture into
the atmosphere.

          Subject the whole to tidal forces induced by
the sun and a captive satellite.

          Then try and predict the conditions of one
small portion of the atmosphere for a period of
one to several days in advance.
