One other thing tweaks my curiousity though. Its well known that low level atmospheric heating occurs due to the mere fact of the presence of a city. Its all the buildings and pavement, and in winter, the radiative heat from buildings with central heat systems. If the effects he says his pictures show are due to atmospheric heating then I believe that city heat is more likely the culprit.
The video linked in the opening post isn't detecting urban heat islands. And Dutchsinse isn't altering the images. It is a quirk of Intellicasts composite RADAR display.
Intellicast attempts to depict precipitation type by color. Ran is green, yellow, orange, red. Mixed precipitation (sleet, freezing rain, rain mixed with wet snow) is depicted by shades of pink. Snow is shades of blue. The radar itself doesn't measure the temperature. Intellicast integrates data from the RAWS (realtime automated weather station) network to guess at what is actually reaching the ground. RADAR just tells the intensity of the precip. Intellicast is using surface observations to guess at what the RADAR is detecting and coloring the map accordingly. Intellicast has gotten better at this since they introduced it in the late 1990s. Heck, they've encorporated digital elevation models into their algorithm such that they show different p-type in along ridges and valleys (hurricane/nor-easter Sandy produced an elevation dependent rain/snow event over WVA and western PA and the intellicast radar map was very interesting).
Those "warm spots" are around weather stations that are biased warm and are outliers. The RADAR is reporting incorrect p-type there and then extrapolating that to the surroundings.
In the following post (linked in the above Dutchsinse video in which he claims that radio transmitters and weather RADARs are heating the atmosphere by microwaving it) he insists that the transmitters are instead cooling:

This lone spot stood out as odd — the only spot in a rain storm showing as "snow AND ice" at once over a stationary spot — the color coded precipitation, showing as becoming frozen, does NOT move with the rest of the storm as it passes by.
If you look to see what is at the center of the frozen spot — an antenna resides directly there. What are the chances?
Here is the antenna information:

So Dutchsinse is simultaneously claiming that the antennas can produce either cooling or heating in the atmosphere directly over the transmitter. That doesn't make much sense in light of his broader post linked at the beginning of this thread where he insists that all the microwave transmitters out there are accidentally heating the atmosphere like his GE Microwave Oven heats his Hot Pockets. It also makes no sense in that the antennas are not omnidirectional broadcasting up and out over top of themselves.

The chances are pretty high since there is also a RAWS station there. The RADAR isn't measuring a stationary spot of snow. The RADAR is detecting precipitation moving over that spot and the weather station is feeding incorrect temperature data to the RADAR so the RADAR thinks that the p-type there is different. The "frozen spot" doesn't move because the thermometer on the ground doesn't move.
Dutch might want to ask himself, how much energy would an antenna have to beam into the sky to heat 5 cubic kilometers of snow enough to melt it. He might also try to figure out how to heat snow with microwaves since dialelectric heating doesn't work very well on solid water.
I personally would like to know how he hypothesizes that an "antenna produces cooling in the atmosphere" or how a radio wave that passes through air then heats air that does not contain any liquid water (he insists that radars are heating air in advance of weather too).
