Potential increases in PM10 concentrations may increase to moderate or unhealthy level.
|Imperial County Weather Synopsis
|SYNOPSIS FROM THE SAN DIEGO OFFICE
Slightly warmer for inland areas today under strengthening high pressure. Slightly cooler Tuesday...then greater cooling for Wednesday and Thursday as a low pressure trough moves inland across California. Strong and gusty winds will accompany this system, along with much cooler weather. There may even be a few brief showers Wednesday evening. Then, warmer and dry into the weekend
High pressure aloft will strengthen slightly today with slight inland warming...with slight cooling near the coast as weak onshore flow returns. Onshore flow will begin to strengthen on Tuesday in a advance of a trough of low pressure that will move inland through California on Wednesday. The non-GFS solutions are favored which are a little faster and less-amplified with the trough passage. Some patchy stratus may return near the San Diego County coast late tonight into Tuesday morning...with a greater return expected for Tuesday night into Wednesday morning... extending into the western valleys. Gusty southwest to west winds will strengthen to near advisory strength near mountain ridge tops and along desert mountain slopes into adjacent desert areas on Wednesday afternoon
SYNOPSIS FROM THE PHOENIX OFFICE
High pressure building over the region today and Tuesday will cause additional warming which will lead to much above normal temperatures by Tuesday...near records at some locations. A low pressure system will then move through the western states midweek. As a result, a dry cold front will move through the area Wednesday night and Thursday for breezy to windy conditions. Much cooler temperatures can be expected Thursday and Friday...dropping several degrees below normal. High pressure and warmer temperatures can be expected over the weekend
