This is still an experimental article (we are working to be sure all the images update)
Here is what we are paying attention to this evening and the next two days from this afternoon’s NWS Forecast:
...Showers and thunderstorms with excessive rainfall and severe weather possible through midweek from the Northern Rockies and High Plains to the Mid Atlantic and Southeast... ...Dangerous heat and humidity to continue from parts of the central and southern Plains to the Mid Atlantic and Southeast...
Outlook for the Week
An ongoing severe thunderstorm complex, producing widespread damaging winds across South Dakota will likely persist, with severe weather continuing into southwest Minnesota and northern Iowa this evening before diminishing overnight. This system developed along a slow-moving frontal boundary that is expected to drift south from the northern Plains and Great Lakes into the central Plains, Ohio Valley, and Mid Atlantic over the next couple of days. This front will likely remain a focus for unsettled weather through midweek, with showers and storms developing along it each day. Some of these storms may become strong to severe, with damaging winds, large hail, and flooding rains possible.
Severe storms are also likely to develop both tomorrow and Thursday over the northern Rockies and High Plains, where large hail and damaging winds are possible. While cooler temperatures are expected across the northern Plains and Upper Midwest tomorrow, dangerous heat and humidity is expected to persist south of the front. With overnight lows forecast to remain in the 70s in most locations, before heat indices reach into the triple digits once again tomorrow, Heat Advisories and Excessive Heat Warnings cover a broad portion of the central and southern Plains, the mid and lower Mississippi Valley, the lower Ohio and Tennessee valleys, as well as parts of the coastal Mid Atlantic and Southeast.
While much of the central and eastern U.S. remains hot, seasonal to below-average temperatures are forecast along the West Coast and into the Great Basin, Southwest, and the central to southern Rockies. Some afternoon and evening showers and storms are possible from eastern Arizona and New Mexico into the southern and central Rockies, continuing the anomalously wet start to the summer across that region.

This should play out something like shown in this 60 Hour Forecast Animation
Here is a national animation of weather fronts and precipitation forecasts with four 6-hour projections of the conditions that will apply covering the next 24 hours and a second day of two 12-hour projections the second of which is the forecast for 48 hours out and to the extent it applies for 12 hours, this animation is intended to provide coverage out to 60 hours. Beyond 60 hours, additional maps are available at links provided below. The explanation for the coding used in these maps, i.e. the full legend, can be found here although it includes some symbols that are no longer shown in the graphic because they are implemented by color-coding.

Now the Day 3 – 7 Hazards Outlook Maps
The orange and red outlined areas are what is most concerning of the forecasted Day 3 – 7 Hazards. This graphic does not update during the weekend. There is a discussion that goes with this graphic and you can access that discussion here.

I have not figured out how to have these maps update. So you will have to click on the links provided. You will get the updated forecasts plus a lot of additional information. Once a week I will provide those maps either in this article or more likely in a separate article. They are here for you right now you just have to click the link.

Now to our More Detailed Weather Report
500 MB Mid-Atmosphere View
The map below is the mid-atmosphere 3-Day chart rather than the surface highs and lows and weather features. In some cases, it provides a clearer less confusing picture as it shows only the major pressure gradients. This graphic auto-updates so when you look at it you will see NOAA’s latest thinking. The speed at which these troughs and ridges travel across the nation will determine the timing of weather impacts. This graphic auto-updates I think every six hours and it changes a lot. Thinking about clockwise movements around High-Pressure Systems and counterclockwise movements around Low-Pressure Systems provides a lot of information.

This graphic is about Atmospheric Rivers i.e. thick concentrated movements of water moisture. More explanation on Atmospheric Rivers can be found by clicking here or if you want more theoretical information by clicking here. The idea is that we have now concluded that moisture often moves via narrow but deep channels in the atmosphere (especially when the source of the moisture is over water) rather than being very spread out. This raises the potential for extreme precipitation events.

World Forecast
Forecast for Day 6 (Currently Set for Day 6 but the reader can change that)
World Weather Forecast produced by the Australian Bureau of Meteorology. Unfortunately, I do not know how to extract the control panel and embed it into my report so that you could use the tool within my report. But if you visit it Click Here and you will be able to use the tool to view temperature or many other things for THE WORLD. It can forecast out for a week. Pretty cool. Return to this report by using the “Back Arrow” usually found top left corner of your screen to the left of the URL Box. It may require hitting it a few times depending on how deep you are into the BOM tool.
Below are the current worldwide precipitation and temperature forecasts for six days out. They will auto-update and be current for Day 6 whenever you view them. If you want the forecast for a different day Click Here
Again, please remember this graphic updates every six hours so the diurnal pattern can confuse the reader.
