Tomorrow, Sunday, is looking much warmer than today. Skies will
be clear to mostly clear and dry again but afternoon temps jump
into the 90s to near 100F. With the hot air, relative humidity
will dip to around 10 to 25%, lowest percentages will be in
northeast Wyoming and southwest South Dakota. Wind speeds in the

chances. While the overall pattern has an upper level high
pressure building over the desert southwest, a ridge riding low
