Weather Eye: July 4 weather worth celebrating, but handle fireworks with care

Pleasant temperatures for the next several days are on tap as we see our brief heat wave in the rear-view mirror. A typical summer day today with morning clouds and afternoon sunshine with highs in the 70s — can't beat that! I think around fireworks time it will be cool and breezy.

Still no rain or thunderstorms in sight so the dry weather continues and boy the ground and vegetation is drying out quickly, so be careful with those fireworks.

I always like to look back on holidays and see what I was writing about. Ten years ago today I wrote this: "Happy Fourth of July! It should be a great day weather-wise for the festivities, near perfect I would say. A weak weather front was on tap for later tonight for cooling and some clouds. Hopefully that northwest wind will remain somewhat calm for the big show tonight. It is still a good idea to carry a sweater or light jacket." I say ditto for today.

With all the high-tech electronic ways of measuring the outside temperature now, it wasn't always that easy. Measuring temperatures before the year of 1600 was a challenge as there were no thermometers. Galileo made the first air thermometer in 1592. Inventors knew that liquids would rise in a glass tube, but to what scale was the problem.

Athanasius Kircher in 1620 used the first thermometer with mercury. The first scale or division was used by Sebastiano Bartold in 1679.

We have come a long way for sure!
