This past weekend was beautiful. Even the temperature was wonderful. It was in the range were you could wear either shorts or pants and not feel cold or hot. This week and into end of the school year should be almost perfect as temps rise into the 70s and higher. This weekend looks to be bringing with it some rain but it shouldn't be anything like last week. 

Above is the current pattern of the jet streams at 250 hPa. It looks like this may be the beginning of an omega pattern for the US. If the jet streams move the way I anticipate and follow he arrows I drew in we should expect to see perfect weather for a very long time. For tomorrow expect more clouds and wind accompanied by higher temps and less humidity.
