While the overall forecast calls for mostly clear skies across the region, smoke and haze from a few California fires could settle into the valleys periodically, especially in the late night/early morning hours. An exiting British Columbia trough and an approaching Pacific trough will balance each other out a bit and keep our temperatures within a few degrees of average.
Winds are always at the forefront of many of our minds on the 4th of July. While criteria will vary depending on where the fireworks displays are occurring, generally most pyrotechnicians want the winds to drop to 10 mph or less. Wednesday evening’s winds will likely be in excess of that prior to the sun setting, after which they should ease steadily through the night. While some delays could occur, it’s likely that the displays should be able to eventually get underway.
Temperatures will remain near seasonable through Friday, after which the ridge builds back in, sending the mercury soaring to well above average levels, giving triple digits a scare by the end of the weekend.
