TORRID HEAT- A DANGEROUS SITUATION
It has been extremely hot on Wednesday. The high temperatures across our region have ranged from 107° to 111°. This is dangerous heat with discomfort indices in the "moderate heat stress" category.
Please respect the heat during hot weather episodes such as Heat Wave #4. Your life could be endangered with the high heat and high ozone combination in the south valley. This heat is expected to increase a bit with overnight lows in the low 80s and a persistent southeasterly mid level wind. I'm forecasting the hottest weather to be on Friday with some moderation thereafter. Over the weekend a weak trough of low pressure will drift across northern California helping to reduce the temperatures in the San Joaquin Valley a little. Highs peak on Friday near 111° with locally higher values.
By Sunday we're down to 104°. Triple digits continue into next week with a trend toward slightly cooler weather again by the end on the 10-day forecast period. The following weekend should see a return to the 90s. I've included a minor chance for afternoon thunderstorms over the Kern County mountains this weekend, due to increase precipitable water in the atmosphere. But only isolated thunderstorms are expected, while the bulk of any convection stays to our north in the high Sierra through the period.
