Potential increases in PM10 concentrations may increase to moderate or unhealthy level.

Imperial County Weather Synopsis
SYNOPSIS FROM THE SAN DIEGO OFFICE
High pressure aloft will bring much warmer high temperatures through Wednesday with slight cooling for Thursday. Surface high pressure over the western plains into New Mexico will bring periods of gusty winds near the coastal foothills and inland valleys into Thursday...strongest on Wednesday. High pressure aloft will weaken for Friday into early next week. This will bring cooling...but with high temperatures remaining above average

High pressure aloft will bring much warmer high temperatures for today and Wednesday with slight cooling for Thursday. Combined with weak to locally moderate offshore flow...this will push warmest high temperatures for inland coastal and western valley areas into the lower to mid 90s on Wednesday with high temperatures well into the 80s toward the coast. Surface high pressure over the western plains into New Mexico will bring periods of gusty east winds near the coastal foothills of the mountains into the valleys of San Diego and Riverside Counties and inland Orange County with the strongest and most widespread winds on Wednesday

SYNOPSIS FROM THE PHOENIX OFFICE
Dry conditions with well above normal temperatures can be expected today under strong high pressure over the desert southwest. Somewhat cooler temperatures can then be expected from Wednesday onward into next weekend as a low pressure system develops over northern Mexico. Breezy to locally windy conditions can be expected today and Wednesday...mainly east of the Lower Colorado River Valley
