Today is in line to be similar to yesterday. We do have some morning fog to contend with but that should dissipate before noon. We'll have quite a bit of sunshine but with that comes continued dryness for much of KELOLAND. Highs will largely be in the middle 80s, but will break 90 far west and south.
The setup brings east winds for the next couple of days. We have a strong surface high in southern Canada and a weak low just to our south. Tonight there is a slim chance that storms developing in western Nebraska will travel northwards to the southern Black Hills.
Tomorrow morning could have some more patchy fog just due to the setup. We'll have high dew points and mainly lighter overnight winds. Sioux Falls and Aberdeen should be about the same but warmth spills out of the Rockies soon.
We'll build on warmth, peaking Tuesday West River and Wednesday/Thursday farther to the east. Tuesday, some of us could hit 100. We don't get that a lot, but with dry ground and an overhead ridge, it's within the realm of possibility. Some indicators want to go even hotter but I am not convinced of that yet. There is a slight cooldown following but it will still be hot. East River Wednesday morning looks like the most humid on the way to the hottest day of the coming seven. While it will be tougher to break into the lower 90s, it doesn't seem like a big challenge at this point.
Thursday, the ridge breaks down slightly and we get a few isolated storm chances.
