|June 28 2017|
|High wind levels have the potential to suspend particulate matter into the air. High levels of PM10 may pose an impact to public health. It is recommended that active children and adults, and people with respiratory disease, such as asthma, limit their outdoor activities.
Potential increases in PM10 concentrations may increase to moderate or unhealthy level.
|Imperial County Weather Synopsis|
|SYNOPSIS FROM THE SAN DIEGO OFFICE
Stronger onshore flow and weakening high pressure aloft will bring a cooling trend today and Thursday. Low clouds and fog will spread farther into the valleys each day. Slightly warmer Friday and Saturday under weak high pressure aloft, then minor cooling Sunday and Monday. Although Tuesday was still quite hot, the heat wave is finally coming to an end. The center of the upper high that brought all the heat has been forced southward into central Baja by a trough moving across the Great Basin. Lower heights and stronger onshore will result in about 5 degrees of cooling compared to Tuesday. Highs Thursday will be similar with temperatures about where they should be for late June.
SYNOPSIS FROM THE PHOENIX OFFICE
A dry airmass will remain over the region through the rest of the week with temperatures moderating closer to average. Though high temperatures will finally drop below 110 degrees, readings will still end up in a slightly above normal range through early next week. Skies will remain mostly clear as the monsoon wind pattern has yet to be established and storm activity will stay well south across Mexico.
