Mainly clear skies across the region early this morning other than a few high clouds along the upper level front as it moves slowly south and some subtropical high cloudiness moves up from the southwest. Current temperatures range from the 40s in the mountain valleys to the mid 60s to lower 70s across the Central Valley.
Persistent weak trough along the West Coast will help to keep temperatures close to average today and the Fourth of July before temperatures gradually warm by the end of the week as the trough weakens.
Short-wave pivoting across the northern portion of the state later today may be enough to pop an isolated shower or thunderstorm near Mt Lassen in the afternoon, otherwise dry weather is expected to continue.
Extended Discussion (Sunday through Wednesday)
Ensembles remain in good agreement that a dry shortwave will pass through Sunday and Monday, with high temperatures dipping below normal. Temperatures trend upwards starting Tuesday, though, as the trough shifts eastward and upper level ridging develops. Forecast highs reach into the triple digits over the northern Sacramento Valley, leaning on NBM guidance.
