Key Seven-Day Weather Information

If your app is not receiving notifications, then please email me at beaudodsonweather@gmail.com

No changes to the going forecast.

It will be hot all week.  Humidity levels won’t be as high as recent heat events.  However, the actual air temperature will be hotter.

Widespread 90s are likely into the weekend.  Expect numerous days in the mid-to-upper 90s.  I can’t rule out a few stations hitting 100 degrees.

Yesterday, some locations hit their highest temperatures of the year, thus far.  The same could happen again today.

Heat index values will range from 102  to 108 degrees.  Remember, the heat index is more important to the body than the actual air temperature.

Use care if you must work outdoors.  Check on the elderly.  Make sure your outdoor pets have water and shade.

The only relief could come from a few showers and thunderstorms on Saturday and Sunday.  For now, we will stick with 20% to 30% chances.  I have removed Friday’s chances.

Not everyone will see rain.  But where rain and clouds thicken, it will be several degrees cooler.

A weak cold front will push across the region on Sunday.  Temperatures could be slightly lower on Monday and Tuesday.  For now, it still looks like widespread upper 80s to mid-90s will be the norm.

Hopefully, the data trends a tad cooler.

Let’s Look At The Rainfall Totals Forecast

⚠️ This won’t be exact because the graphic is trying to predict where summer storms will form.

⚠️ Some areas will receive higher totals.  Some areas could miss out on the rain, as well.  Summer thunderstorms can produce a wide range of totals.

NOTES:

Let’s look at the rain probability maps.   What is the % chance of rain?

These maps are broken down into 12-hour time periods.

* Remember, a 20% chance of rain during the summer months does not mean that it will not rain.  It means there will be a few thunderstorms on the radar.

* Future-cast radars are rarely exactly right.  Take the general idea from this animation.  These models do their best to forecast where precipitation will develop and move.  In the end, they are a model.

The timestamp (upper left) is in Zulu.  12z=7 AM. 18z=1 PM. 00z=7 PM.

Green is rain.  Yellow is moderate rain. Orange and red indicate locally heavy rain.

** NEW SERVICE **  I have partnered with WeatherCall to bring you an added layer of protection.
.
More information on the WeatherCall subscription service at the link below or use the QR code.

.
We have a new service to complement your www.weathertalk.com subscription.  This does NOT replace www.weathertalk.com It is simply another tool for you to receive severe weather information.

I use it myself. I encourage everyone to have 3 to 5 ways to receive severe weather information. All sources can fail, and the more sources you have, the better prepared you will be in the event of severe weather warnings.
.
WeatherCall will call your cell phone or home number if your home is under a tornado or severe thunderstorm warning.  It only calls you if your home is inside the warning box/polygon. If you are outside the warning box/polygon, it will not disturb you.
Here is a video with more information and a demonstration of how it works.
