DISCUSSION
KEY MESSAGE 1
ANTICIPATING INCREASING HIGH TEMPERATURES EACH DAY THROUGH
WEDNESDAY. AS USUAL FOR THIS TIME OF THE YEAR, HIGHS WILL BE
TEMPERED IN AREAS CLOSER TO THE COAST, BEING AFFECTED BY AN
ONSHORE WIND COMPONENT. MIXING UP TO 900-850MB AWAY FROM THE
MARINE INFLUENCE IS EXPECTED. 900MB TEMPS ARE PROGGED TO REACH
13-15C ON WEDNESDAY, WITH 850MB TEMPS AT 11-13C. THIS COULD
PRODUCE HIGHS IN THE LOWER 80S IN THE TYPICALLY WARMEST SPOTS IN
THE NE NJ URBAN CORRIDOR AND ADJACENT AREAS. THERE IS HOWEVER
SOME UNCERTAINTY WITH THE AMOUNT OF CLOUD COVER AND SHOWERS THAT
MAY ENTER THE AREA BY THE TIME PEAK HEATING WOULD OCCUR.
CURRENT FORECAST IS DETERMINISTIC NBM WITHOUT ANY ADJUSTMENTS,
AND WHILE THIS FALLS BELOW THE 25TH PERCENTILE, IT'S CONSISTENT
WITH CURRENT THINKING. HIGHS NEAR 80 FOR THE TYPICAL WARMEST
SPOTS WITH 60S AND 70S ELSEWHERE. SOME RECORD HIGHS FOR THE DATE
WOULD BE APPROACHED. RECORD HIGH MINIMUM TEMPERATURES MAY ALSO
BE APPROACHED. SEE THE CLIMATE SECTION BELOW FOR DETAILS.
KEY MESSAGE 2
MAIN UPPER LEVEL JET REMAINS NORTH OF THE AREA WEDNESDAY
THROUGH THE REST OF THE FORECAST PERIOD. JET RELATIVELY CLOSER
WEDNESDAY INTO WEDNESDAY NIGHT AS WELL AS FRIDAY AND POTENTIALLY
NEXT SUNDAY. THESE TIME PERIODS ARE ESSENTIALLY WHERE THE 250MB
WIND SPEEDS ARE GREATER ACROSS THE REGION COMPARED TO OTHER
TIME PERIODS. THIS TAKES INTO ACCOUNT THE AVERAGE DEPICTION
AMONGST DIFFERENT LARGE SCALE NUMERICAL WEATHER PREDICTION
MODELS.
AT THE SURFACE, A COLD FRONT MOVES ACROSS WEDNESDAY NIGHT. THE COLD
FRONT THEN SLOWLY MOVES FARTHER SOUTH THURSDAY AND COULD VERY WELL
STALL OUT. ANOTHER AREA OF LOW PRESSURE APPROACHES FROM THE WEST
FRIDAY INTO THE START OF NEXT WEEKEND. THE MODELS APPEAR TO SHOW THE
FRONT PUSHING BACK NORTH AS A WARM FRONT THURSDAY NIGHT INTO FRIDAY.
AN AREA OF LOW PRESSURE MOVES IN FRIDAY NIGHT INTO SATURDAY WITH
ANOTHER FRONTAL SYSTEM POTENTIALLY APPROACHING ON SUNDAY.
CHANCES OF RAIN ARE PRESENT FROM WEDNESDAY NIGHT THROUGH THE REST OF
THE WEEK ACROSS THE REGION. AT TIMES, RAIN IS MORE LIKELY SUCH AS
WITH THE COLD FRONT WEDNESDAY NIGHT WITH A CHANCE OF
THUNDERSTORMS AS WELL. THE THUNDERSTORM CHANCE IS BECAUSE OF THE
HIGHER INSTABILITY THAT WILL BE PRESENT AHEAD OF THE COLD FRONT
IN THE LOW LEVELS DUE TO THE WARMER AIRMASS IN PLACE AND
VERTICAL FORCING WITH THE COLD FRONT. THERE IS ANOTHER HIGHER
LIKELIHOOD OF RAINFALL THURSDAY NIGHT INTO FRIDAY AND THIS IS
WHEN THAT FRONTAL BOUNDARY MAY MOVE BACK NORTH WITHIN THE REGION
AS A WARM FRONT.
AFTER A MUCH COOLER DAY THURSDAY WITH FORECAST HIGH TEMPERATURES
MAINLY IN THE 50S, FORECAST MAX TEMPERATURES TREND SLIGHTLY WARMER
FRIDAY. FORECAST MAX TEMPERATURES SATURDAY ARE NOT TOO MUCH
DIFFERENT THAN THOSE OF THE PREVIOUS DAY AND ARE FORECAST TO BE
SLIGHTLY WARMER FOR NEXT SUNDAY.
FORECAST MIN TEMPERATURES TRENDED WARMER THAN THE PREVIOUS FORECAST.
SO, RAIN IS THE ONLY PRECIPITATION TYPE IN THE FORECAST MID TO LATE
WEEK.
