KEY MESSAGE 1...
THE 12Z OBJECTIVELY ANALYZED UA CHARTS OBSERVED THAT THE SUBTROPICAL
RIDGE, WHICH IS CURRENTLY CENTERED OVER THE MS RIVER VALLEY, HAS
STRENGTHENED SLIGHTLY COMPARED TO 24 HOURS AGO, WITH GEOPOTENTIAL
HEIGHTS NOW AT 592 DAM AT 500 MB. THE OMEGA BLOCK IS BEGINNING TO
COLLAPSE DUE TO A WELL-DEFINED, POSITIVELY-TILTED SHORTWAVE TROUGH
THAT IS EJECTING OVER THE FOUR CORNERS REGION. HIGH TEMPERATURES FOR
THIS AFTERNOON AND MONDAY WERE MANUALLY RAISED BY A FEW DEGREES, AS
OBSERVATIONS YESTERDAY WERE SLIGHTLY WARMER THAN ANY OF THE NWP
GUIDANCE; AND THIS TREND WILL HOLD AS THE SUBTROPICAL RIDGE BECOMES
CENTERED OVER THE DEEP SOUTH BY MONDAY EVENING. OTHERWISE, DEWPOINTS
WERE ONCE AGAIN LOWERED TO ALIGN CLOSER TO THE DRIER MOS GUIDANCE;
AND PLEASANT FALL WEATHER WILL CONTINUE THROUGHOUT THE UPCOMING WORK
WEEK ACROSS THE ENTIRE CWA. A WEAKENING BACKDOOR COLD FRONT WILL
ALSO SWEEP THROUGH THE REGION DURING THE DAY TUESDAY AND SHIFT WINDS
TOWARDS THE NORTHEAST POST-FROPA. THE PASSAGE OF THIS COLD FRONT
WILL BE RAIN-FREE; HOWEVER, MOISTENING OF THE BOUNDARY-LAYER WILL
OCCUR HEADING INTO WEDNESDAY AS THE MODIFIED MP AIRMASS TRAILING THE
COLD FRONT SETTLES INTO THE REGION. THAT SAID, HIGH-LEVEL CIRROFORM
CLOUDS WILL ADVECT THE REGION LATE MONDAY NIGHT, WITH THE DECK
THICKENING HEADING INTO WEDNESDAY AS A REMNANT SHORTWAVE TROUGH
EJECTS OVER THE CORN BELT. OVERNIGHT LOWS BY THE MIDDLE PART OF THE
WEEK ARE FORECAST TO BE SEVERAL DEGREES WARMER COMPARED TO WHAT HAS
BEEN OBSERVED RECENTLY, AS THE CIRRUS DECK TRAPS OUTGOING LONGWAVE
RADIATION. PROSPECTS FOR RAIN MAY RETURN BY LATE NEXT WEEKEND AS THE
SUBTROPICAL RIDGE DEAMPLIFIES AND RESTORES CYCLONIC FLOW ALOFT.
AVIATION /18Z SUNDAY THROUGH FRIDAY/
VFR WILL CONTINUE INTO EARLY MONDAY MORNING FOR MOST TERMINALS, WITH
VALLEY FOG RETURNING TO KEKN, KPKB, AND BRIEFLY AT KCRW DURING THE
PREDAWN HOURS. WINDS WILL REMAIN LIGHT THROUGH THE TAF PERIOD.
FORECAST CONFIDENCE: HIGH.
ALTERNATE SCENARIOS: THE COVERAGE AND TIMING OF FOG TONIGHT MAY VARY
FROM THE FORECAST.
