DISCUSSION
KEY MESSAGE 1...
THERE IS HIGH CONFIDENCE IN THE UPPER AIR PATTERN FEATURING
SOUTHEAST CONUS RIDGING THAT EXTENDS INTO THE OHIO RIVER VALLEY
SUNDAY INTO NEXT WEEK. THE COMBINATION OF THE HEIGHT RISES AND
WARM ADVECTION WITHIN SOUTHWEST NEAR SURFACE FLOW PUSHES RETURNS
AREA TEMPERATURE CONSISTENTLY IN THE UPPER 70S TO 80S FOR HIGHS
AND UPPER 50S TO 60S FOR LOWS. FOR REFERENCE, THE AVERAGE
HIGH/LOW AT PITTSBURGH DURING THIS PERIOD IS 62/40, RESPECTIVELY.
THIS EARLY SPRING HEAT WILL PUT NUMEROUS HIGH MAXIMUM
TEMPERATURE AND HIGH MINIMUM TEMPERATURE RECORDS AT THREAT OF
BEING TIED OR BROKEN; NBM PROJECTIONS SUGGEST ANYWHERE FROM
20-70 PERCENT CHANCE OF PIT TYING/BREAKING MAX T RECORDS BETWEEN
TUESDAY-FRIDAY. POTENTIAL FOR AFTERNOON CONVECTION AND ANY
RESULTANT CLOUD COVER (PLUS SOME HEIGHT VARIANCES) APPEARS TO BE
THE MOST LIKELY FACTOR FOR HIGH TEMPERATURE READINGS TO FALL
SHORT OF CURRENT FORECASTED VALUES.
KEY MESSAGE 2...
INCOMING SHORTWAVE AND SURFACE COLD FRONT WILL BRIEFLY END FIRE
WEATHER CONCERNS AS RAIN OVERSPREADS THE REGION TONIGHT INTO
SATURDAY MORNING. ENOUGH DRY AIR AND RISING TEMPERATURE COULD
RESULT IN MARGINAL FIRE CONCERNS SATURDAY AFTERNOON INTO MONDAY,
BUT THE SIGNAL IS NOT AS STRONG.
THE LONG RANGE OUTLOOK IS THE BIGGER STORY AS THE COMBINATION OF
NEAR RECORD HIGH TEMPERATURE WITH INCREASING MOISTURE AND
PERIODIC SHORTWAVE MOVEMENT OVER THE RIDGE AXIS CREATES PERIODIC
THUNDERSTORM CHANCES STARTING MONDAY AND THROUGHOUT THE UPCOMING
WEEK. EARLY WEEK CONVECTION IS FAVORED TO BE MORE ISOLATED TO
SCATTERED POP-UP STORMS IN MEAGER (LESS THAN 1000 J/KG CAPE)
STORM ENVIRONMENTS SUGGESTING LIMITED SEVERE CONCERNS. BETTER
UPPER DYNAMICS AND IMPROVED STORM ENVIRONMENTS MAY DEVELOP
DURING THE LATTER HALF OF THE WEEK THAT BEARS MONITORING IN THE
COMING 3-5 DAYS FOR THEIR SEVERE POTENTIAL.
AVIATION /00Z SATURDAY THROUGH WEDNESDAY/
A COLD FRONT WILL CONTINUE TO DROP SOUTHWARD ACROSS THE REGION
THIS EVENING, WITH SHOWERS, MAINLY BEHIND THE FRONT. EXPECT A
DETERIORATION TO IFR OR LOW MVFR FOR ALL AIRPORTS AS LOW LEVEL
MOISTURE INCREASES AFTER FROPA. IFR/LOW MVFR CIGS SHOULD
CONTINUE THROUGH SATURDAY MORNING BEFORE BUILDING HIGH PRESSURE
RESULTS IN DECREASING CLOUDS AND A RETURN TO VFR.
OUTLOOK...
VFR IS EXPECTED SUNDAY AS HIGH PRESSURE MOVES ACROSS THE REGION.
THE POTENTIAL FOR PERIODIC RESTRICTIONS AND
SHOWERS/THUNDERSTORMS RETURN MONDAY THROUGH WEDNESDAY AS A COLD
FRONT APPROACHES THE AREA, AND THEN STALLS.
