Is the heatwave over and what is dewpoint anyway?

Written by  Scott LaMar, Director of Radio Smart Talk

Radio Smart Talk for Tuesday, July 26:

It rained throughout the midstate Monday.  Some areas maybe got a little too much rainfall in too short a period of time and that resulted in flash-flooding, but the rain finally provided relief from the week-long heat wave.  Temperatures in the 90s throughout the week and and a few days that approached 100 degrees left us all parched, looking for a cold drink and trying to find a way to stay cool.

Is the heatwave over?  Will this week's weather be more bearable?  The calendar says late July so we know that it will be hot but was last week's weather an extreme -- even for this time of year?  And what is a dew point anyway?

CBS21 Chief Meteorologist Tom Russell will appear on Tuesday's Radio Smart Talk to answer your weather questions.

From barometric pressure to hailstones, what questions do you have for Tom Russell?

Gentleman,

Went to NYC last Thursday through Sunday, specifically to see Central Park. With the heat I was expecting an empty park. Not so, the activity was astounding, including rigorous exercise. We walked 6+ miles. Living in Florida for 6 years trains one to deal with it and live life regardless.

Within the park there were much cooler areas, which were our rest areas. What study has been done on microclimates?

Man, what a pile of politicized horse muffins, that CO2 levels FOLLOW rising temperatures. There are now 100 ppm more CO2 than there was 60 years ago, and we KNOW where it came from. I don't believe that the good weatherman could scientifically support his statements about global warming. It was cute how he pointed out the warmest year on record being in the 30's, but simply failed to note that he was referencing the lower 48 only, and WAS NOT talking about a global average.

Nothing like cherry picking tidbits to support your position without looking at the big picture. And when you are speaking about GLOBAL climate change, how hot (or cold) it was in Paxtang is just one data point among millions. But it's the nature of the medium that he got to put his view out there unchallenged.

Grrr.

Early on Tom speculated that it was certainly Humid during the great heat wave of early July 1966 (104-107-104F). It was not. 1966 was the 5th + final year of a great drought. We were not getting these 80+ low temperatures. I did a lot of running after dark that summer, and it was comfortable.

It should be noted that other very hot summers were very dry. 1936 "began" with the great March Floods, but March thru October was about as dry as ever.

1955 was drier than 36 until August 11 when Hurricane Carol struck, followed a week later by the monster rain producer, Diane.

1999 was the third consecutive drought year (and 6th of the 90's) It was a rare year in which almost all Pa Counties reached Drought Emergency, the worst status. (broken by Hurricane Floyd)

Hot years 1995 + 2005 were also very dry for almost 6 months.

Continuing

But 2010 was only a dry year, not an extremely dry year.

And 2011 was, although dry in July, very wet the 3 prior months.

It is obvious it takes more heat to reach a given extreme high in high humidity than low. Note that the highest world temperatures are in Deserts, not Jungles - even though the Jungles, not the deserts are what dominate the equator. So, in reality, this July seems to be the most hot+humid if not the hottest in Pa history.

David is correct, it is just ridiculous to say heat increases CO2 levels. Burning Fossil fuels obviously replaces atmospheric CO2 that had been gradually placed in the ground between 500M+100M years ago.

Leave us face it, Tom worked for the extremely right wing Clear Channel, and I suspect his present bosses, Nexstar, are just right wing. - Both are Texas companies.

Fortunately, we did get to hear a real climate Scientist, Heidi Cullen, yeserday on Terry Goss's show.
