DISCUSSION
KEY MESSAGE 1: SIGNIFICANT WARMING TREND INTO THIS WEEKEND
BEFORE A COLD FRONT MOVES IN EARLY NEXT WEEK.
STRONG RIDGING IS CURRENTLY IN PLACE OVER THE SOUTHWEST. A
REMARKABLY LARGE FOOTPRINT OF EFI GREATER THAN 0.99 FOR MAX
TEMPERATURES FOR MUCH OF THE CONUS WEST OF THE ROCKIES. AS THIS
RIDGE SLOWLY SHIFTS TO THE EAST, A WARMING TREND WILL CONTINUE OVER
THE FORECAST AREA WITH ABOVE AVERAGE TEMPERATURES BY TOMORROW,
CONTINUING INTO EARLY NEXT WEEK. NAEFS MEAN HAS TRENDED A BIT HIGHER
WITH 850MB TEMPERATURES BY THIS WEEKEND, ONCE AGAIN ABOVE THE 90TH
PERCENTILE. THIS WILL LEAD TO HIGH CONFIDENCE OF WELL ABOVE AVERAGE
TEMPERATURES THIS WEEKEND WITH HIGHS IN THE LOW TO MID 80S SATURDAY
TO MID TO UPPER 80S SUNDAY. SURFACE HIGH PRESSURE EXPECTED TO SHIFT
SOUTH OF THE AREA WHICH ALONG WITH A LOW PASSING TO THE NORTH WILL
LEAD TO INCREASING LOW LEVEL MOISTURE. SOME WEAKNESS IN THE RIDGE,
GENERALLY OVER THE NORTHERN PORTION OF THE FORECAST AREA COULD LEAD
TO AN ISOLATED SHOWER THIS WEEKEND BUT BLENDED GUIDANCE KEEPS POPS
AROUND 10 PERCENT. GUIDANCE HAS GENERALLY TRENDED SLOWER WITH A
FRONT EARLY NEXT WEEK AS THE ASSOCIATED TROUGH BEGINS TO DIG SOUTH A
BIT LATER AND FARTHER EAST. THIS HAS LED TO MORE CONFIDENCE IN
TEMPERATURES MONDAY REMAINING WELL ABOVE AVERAGE WITH BLENDED
GUIDANCE ALSO TRENDING DRIER WITH THE FRONT ITSELF WITH SLIGHT
CHANCE OF RAIN SHOWERS OR POSSIBLY AN ISOLATED STORM MONDAY.
AVIATION /18Z THURSDAY THROUGH TUESDAY/
VFR CONDITIONS THROUGH THE PERIOD.
THIN CIRRUS CONTINUES TO PERIODICALLY STREAM OVER THE REGION THIS
AFTERNOON, AND THIS WILL CONTINUE INTO FRIDAY. LIMITED LOW-LEVEL
MOISTURE INCREASE TONIGHT SHOULD CONTINUE TO KEEP VISIBILITIES VFR
AT ALL TERMINALS. WINDS WILL BE LIGHT AND VARIABLE THROUGH SUNSET,
THEN BECOMING CALM OVERNIGHT. AS THE CENTER OF THE SURFACE RIDGE
SHIFTS EAST FRIDAY, WINDS WILL TURN MORE OUT OF THE SOUTH TO
SOUTHWEST BY LATE MORNING, BUT SPEEDS STILL ONLY AROUND 5 KNOTS.
EXTENDED AVIATION OUTLOOK... AS MOISTURE CONTINUES TO SLOWLY
INCREASE OVER THE WEEKEND, THERE WILL BE A SLIGHTLY BETTER CHANCE OF
MORNING STRATUS AND FOG, BUT CHANCES FOR RESTRICTIONS ARE STILL NOT
TOO HIGH. A COLD FRONT WILL APPROACH FROM THE NORTH ON MONDAY,
INCREASING THE CHANCES FOR SOME CLOUDS AND SHOWERS AHEAD OF IT.
