Active In The Middle &What Exactly Is A "Chance"

It will be an active weather weekend for the center of the nation as a storm system with a lot of wind pull out of the west.

It will bring some showers, thunderstorms and even snow (above 8500 feet) to the inter-mountain west and severe thunderstorms from the pandhandles of Texas and Oklahoma all the way to the Great Lakes vicinity.

The hot spot right now looks to be southwest Kansas down into west Texas where very large hail and some tornadoes are anticipated to develop.

So you see all the time in the forecast that there is a "chance" for rain or some type of weather phenomena, right?

So what does that mean exactly?

Precipitation (or "pop", as forecasters routinely call it) is defined as the likelihood of occurrence of a measurable amount of liquid precipitation (or the water equivalent of frozen precipitation) falling during a specified period of time at any given point in the forecast area.

I found a great write-up of this on the weather page for the National Weather Service in Grand Junction, Colorado. Click here to read.

I know we have some bloggers in the CoCoRaHS Community. If you are a blogger, will you send me a link to your blog or your weather homepage?

OSNW3 I have yours.

Dewdrop -- I know you host one but I don't have the link at hand.

Those are the first two that came to mind this early in the morning.

I am packing up for a quick little weekend roadtrip over to the western slope. That is what we call the locations west of the Continental Divide here in Colorado.

Some friends and I are having a relaxing weekend at Glenwood Springs. Home to one of the largest hot springs mineral pools in the world. We are also going to the vapor caves, which are caves that have 100°+ waters flowing though, apparently with a lot of steam.

And the "vapor" relaxes you and is good for the skin with all the natural minerals and such you will absorb.

Maybe I will get my next big brainstorm out there as I relax and chill out over the next 2 days from all the stresses for working 2 jobs and paying off a truckload of high debts. ;-)

As I am sure 99 out of 100 can relate to.

Have a great weekend and for all those in the areas for strong to severe thunderstorms this weeekend -- keep an eye to the sky, have your severe weather action plan in place, and be safe!


  1. Chris, how exciting. Please share photos and the epiphany or two that may come your way while in the caves... :)

    It was down right hot in Oshkosh, WI yesterday. Dewpoints in the lower 60's and temps in the upper 70's lower 80's. I recorded 79.7, just missing the 80 mark!

  2. I am a blogger, and my (weather-related) site is But this requires a bit of explanation.

    The blog is largely aimed at anyone living in the flood plain upon which a good portion of the neighborhood is sitting. It's meant to keep track of heavy rain amounts and correlate them with damage on the ground - I noticed that 8.5"-10" of rain last September might only cause street closures in most areas, but it definitely put up to 1.5 feet of water into the main levels of homes in our neighborhood, and four inches of water in my garage (given that the garage is 99% of the time some 3-4 feet above the creek, this was a bit of a shock.)

    Since then we've had 3.5" and 4.5" events, and the effects of those have been documented fairly well.

  3. Chris,

    I started a blog earlier this year, the link is

    I try to keep track of the weather events at this station...sort of an extention to the "Observation Notes" on my daily report.

  4. Chris:
    I started a blog in January. Here is the link:

    My daily CoCoRaHS observations coupled with my personal weather station are the bulk of the content. There are some unique posting and photos too.
