MOSQUITOES
Mosquitoes rise when the snows melt.
Mosquitoes are typically THICK right now.
A dry year? Then less skeeters. A wet year? Then more.
2015 was a good model for dry years, being the driest on record.
2017 provides a good model for wet years, as it recorded the most snow ever measured.

Heat threat dissapated
into warm temps-not cool, but warm. Heat to increase again this weekend, so be heat and fire aware.
Tropical Power Marching North
A unique configuration of factors has formed up a "storm generation machine" (news) in the waters off of Central America for the past couple of weeks. A line of storms aimed at Hawaii have been deflected, swatted away to the Southwest and disrupted by the rotation of the powerful, persistant High covering the NE Pacific.
Now these big tropical storms are marching far enough North that remnants of their massive moisture plumes could be swept East on prevailing winds, and across the Sierra during the next week-weeks.
This means that the chances of tropical thunderstorms and downpours are increasing.
