DISCUSSION FOR ORANGE ECC DISPATCH
554 AM PDT TUE SEP 19 2017

A TROUGH OF LOW PRESSURE OVER THE WESTERN STATES WILL MAINTAIN
STRONGER ONSHORE FLOW AND BELOW AVERAGE HIGH TEMPERATURES THROUGH
FRIDAY WITH THURSDAY AND FRIDAY THE COOLEST DAYS. A MARINE LAYER
NEAR 3500 FEET DEEP WILL BECOME DEEPER THURSDAY AND FRIDAY WITH
SMALL CHANCES FOR LIGHT PRECIPITATION THURSDAY. STRONGER ONSHORE
FLOW WILL BRING PERIODS OF STRONG GUSTY WEST WINDS FOR THE MOUNTAINS
AND DESERTS WEDNESDAY AFTERNOON THROUGH THURSDAY NIGHT. HIGH
PRESSURE ALOFT WILL STRENGTHEN OFF THE WEST COAST THIS WEEKEND WITH
SURFACE HIGH PRESSURE DEVELOPING OVER THE GREAT BASIN EARLY NEXT
WEEK. THIS WILL BRING A WARMING TREND WITH MUCH LOWER INLAND
HUMIDITIES POSSIBLE EARLY NEXT WEEK. THOSE LOW HUMIDITIES COMBINED
WITH LOCALLY GUSTY NORTHEAST WINDS NEAR THE COASTAL FOOTHILLS AND
BELOW PASSES AND CANYONS WOULD INCREASE THE POTENTIAL FOR MORE RAPID
FIRE SPREAD.
