KEY MESSAGE 1
AN UPPER LOW OVER THE AREA THIS MORNING WILL PASS TO THE EAST
TODAY WITH ISOLATED TO SCATTERED SHOWERS. HIGHEST COVERAGE WILL
BE THIS AFTERNOON ACROSS SOUTHERN CT AND EASTERN LI. STEEP LOW-
LEVEL LAPSE RATES, CYCLONIC FLOW, AND LOW-LEVEL MOISTURE SHOULD

W-NW WINDS MAY GUST 15 TO 20 MPH.
HIGHS TODAY ARE FORECAST TO GET UP INTO THE 60S, SLIGHTLY BELOW
NORMAL FOR MOST LOCATIONS.
KEY MESSAGE 2
UPPER LEVEL RIDGING BUILDS IN TONIGHT THROUGH EARLY SATURDAY,
THEN FLATTENS SOME FOR THE REST OF THE WEEKEND BEFORE SIGNIFICANT
HEIGHT RISES WORK INTO THE EASTER THIRD OF THE COUNTRY EARLY
NEXT WEEK. THE LATTER OF WHICH WILL RESULT IN A SIGNIFICANT
WARMUP, WITH HIGHS 15 TO 20 DEGREES ABOVE NORMAL FOR TUESDAY
AND WEDNESDAY. AT THIS TIME, FORECAST HIGHS FALL WELL SHORT OF
RECORD HIGHS, WITH MANY WELL INTO THE 90S.
BEFORE THEN THOUGH, TEMPERATURES WILL STEADILY INCREASE THROUGH
THE WEEKEND, WITH HIGHS IN THE 70S TO LOWER 80S SATURDAY, THEN
INTO THE 80S FOR MOST LOCATIONS ON SUNDAY. HIGHS COULD GET
CLOSE TO 90 ACROSS METRO NE NJ. BDR AND ISP ARE FORECAST TO BE A
FEW DEGREES SHORT OF RECORD HIGHS SUNDAY, WHICH IS 85 SET BACK
IN 1974.
THE HIGH TEMPERATURE FORECAST REMAINS A BIT TRICKY AS THE NBM5.0
CONTINUES TO LOOK TOO WARM, ESPECIALLY NEAR THE COAST. HAVE
GENERALLY ADJUSTED IT DOWNWARD FOR HIGH TEMPS A COUPLE OF DEGREES
SATURDAY AND SUNDAY. MUCH OF THE GUIDANCE IS STILL A BIT COOLER
THAN THESE VALUES AS WELL. WHAT IS INTERESTING, IS THE NBM BOX
AND WHISKER PLOTS SHOW VERY SMALL DIFFERENCES OVER THE WEEKEND
BETWEEN THE 25TH AND 75TH PERCENTILES. THE MEDIAN AND NBM
DETERMINISTIC ARE NEARLY ON TOP OF EACH OTHER. SO THIS TELLS US
THERE IS NOT MUCH SPREAD IN THE GUIDANCE, HOWEVER, THE BIAS
ALGORITHMS MAY BE STILL ADJUSTING HEADING INTO THE WARM SEASON.
TIME WILL TELL.
GLOBAL MODEL GUIDANCE FOR MIDWEEK CONTINUES TO SHOW A BREAK
DOWN OF THE UPPER-LEVEL RIDGE IN RESPONSE TO A CLOSED UPPER-LOW
TRAVERSING CANADA. RAIN CHANCES INCREASE WITH A COOL DOWN FOR
THE END OF THE WEEK.
