The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS New York, NY wrote its last area forecast discussion before the first event at Mar 3, 12:45 PM EST, 2 hours 30 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE UPTON NY 1245 PM EST SAT MAR 3 2007 .NEAR TERM (THIS AFTERNOON AND TONIGHT)... 12Z RUNS INDICATE SLIGHTLY SLOWER PASSAGE OF THE COLD FRONT THAN PREVIOUSLY THOUGHT. IT NOW APPEARS AFTER FURTHER ANALYSIS THAT ALL THAT PASSES THIS AFTERNOON IS A PRE-FRONTAL TROUGH WITH SOME SUPPORT FROM A 70+ KT 500MB JET. THE MAIN COLD FRONT DOES NOT COME THROUGH UNTIL TOWARDS MIDNIGHT TONIGHT...SO HAVE REDUCED POPS THIS AFTERNOON TO SLIGHT CHANCE AND INCREASED POPS THIS EVENING TO CHANCE. ALSO HAVE REMOVED MENTION OF THUNDER IN THE ZONES AS WELL. DO STILL HAVE (AFTER MORNING INVERSION IS ELIMINATED) AN INVERTED V SOUNDING AT BOTH OKX AND ALY WITH 50-60KT OF WIND NEAR THE NOTCH OF THE V (AROUND 650MB)...SO STILL COULD GET SOME GUSTY WINDS WITH ANY SHOWERS ASSOCIATED WITH THE FRONTS PASSAGE. TEMPERATURES WERE ALREADY APPROACHING FORECAST HIGHS...SO RAISED BY A CATEGORY...HOWEVER THIS STILL HAS THEM BELOW THE TRIGGER TEMPERATURE OF 61-62 DEGREES FOR DEEP CONVECTION IN THIS MORNINGS SOUNDINGS. BEHIND THE FRONT THINGS WILL TURN COLDER (COMPARED TO LAST NIGHT)...LOWS SEEMED ON TRACK SO MADE NO CHANGES THERE. && .SHORT TERM (SUNDAY THROUGH MONDAY)... GENERAL TROUGH WILL REMAIN OVER THE AREA ON SUNDAY. THIS MAY LEAD TO A FEW MORE CLOUDS...AS WELL AS COLDER TEMPERATURES FOLLOWING THE COLD FRONTAL PASSAGE LATE SATURDAY. AN ARCTIC FRONT WILL DROP DOWN FROM CANADA ON MONDAY...AND SHOULD PUSH THROUGH THE REGION EITHER DURING THE LATE AFTERNOON OR EARLY EVENING. BUFKIT SHOWED A SIMILAR INVERTED V PROFILE ON MONDAY AS IT DOES FOR LATER THIS AFTERNOON. THAT COMBINED WITH A MID LEVEL SHORTWAVE AND THE PROXIMITY OF THE MID AND UPPER LEVEL TROUGH OVER NEW ENGLAND PROMPTED THE ADDITION OF SLIGHT CHANCE POPS FOR MONDAY AFTERNOON AND EVENING. MOISTURE MAY BE LIMITED AT LOW LEVELS...SO CONFIDENCE IN THIS EVENT REMAINS LOW. && .LONG TERM (MONDAY NIGHT THROUGH FRIDAY)... FOLLOWED HPC GRAPHICS/GUIDANCE CLOSELY FOR LONG TERM PERIOD. MOST INTERESTING WEATHER CONCERN THIS PERIOD IS THE COLD THAT MOVES ON BACK SIDE OF DEEP TROUGH. H8 HPA TEMPS < -20C...AND MEX AND HPC NUMBERS QUITE COLD IN THE 20S...WITH SINGLE DIGITS/TEENS MONDAY NIGHT. OTHERWISE...DRY FOR THE MOST PART WITH LACK OF ANY SIGNIFICANT STORM APPARENT. COLDER THAN NORMAL MONDAY THROUGH WEDNESDAY...WITH A WARM-UP ON THURSDAY ON BACK SIDE OF SURFACE HIGH...ALONG WITH FLATTENING OF UPPER FLOW. NEXT WEAK FRONT APPROACHES THURSDAY NIGHT AND FRIDAY...AND THAT WOULD BE OUR BEST CHANCE FOR ANY PRECIP. && .AVIATION... VFR CONDITIONS EXPECTED FOR MOST OF THE TAF PERIOD. A COLD FRONT WILL CROSS THE AREA LATE THIS AFTERNOON AND COULD BE ACCOMPANIED BY GUSTY SHOWERS BRINGING BRIEF MVFR CONDITIONS. CONFIDENCE IN THUNDER IS SHRINKING AND IF NO LIGHTENING OBSERVED SHORTLY...WILL REMOVE CB REFERENCE FROM 18Z TAFS. STILL ON TRACK FOR GUSTY SW WINDS (25-35KT) WITH PASSAGE OF PRE-FRONTAL TROUGH THIS AFTERNOON MAINLY 20-23Z WINDOW WEST AND 22-01Z WINDOW EAST. OTHERWISE VARIABLE WINDS AT 5-10KT UNTIL WINDS STEADY UP OUT OF THE WEST AT AROUND 10KT (A LITTLE HIGHER AT CITY TERMINALS) BEHIND THE FRONT LATE TONIGHT. && .MARINE... MAIN CHANGE WITH THE UPDATE THIS MORNING WAS TO CONVERT SCA FOR HAZARDOUS SEAS TO JUST AN SCA AS EXPECT GUSTS TO SCA FORCE TO DEVELOP THIS EVENING WITH CAA BEHIND THE FRONT. SEAS REMAIN HIGH ON THE OCEAN WATERS...WELL ABOVE SMALL CRAFT LEVELS...THIS MORNING. SEAS WILL GRADUALLY SUBSIDE THROUGHOUT THE WEEKEND...HOWEVER THEY MAY NOT COME DOWN BELOW 5 FT ON THE OCEAN WATERS UNTIL LATE SUNDAY. OTHERWISE...QUIET CONDITIONS CAN BE EXPECTED ON THE SOUND/HARBOR THROUGH SUN MORNING. SCA MAY BE NEEDED ON THE SOUNDS AND HARBOR SUNDAY AFTERNOON AS A TROUGH IS FORECASTED TO MOVE ACROSS THE AREA...BRINGING GUSTY CONDITIONS AND SOME COLDER AIR. A COLD FRONT WILL MOVE ACROSS THE REGION MONDAY...THIS WILL RESULT IN SUSTAINED WINDS AND GUSTS LIKELY REMAINING AT OR ABOVE SMALL CRAFT LEVELS. HIGH PRESSURE WILL BUILD INTO THE REGION LATE TUESDAY NIGHT AND WEDNESDAY ALLOWING WINDS TO SUBSIDE BELOW SCA. && .HYDROLOGY...RIVERS AND STREAMS HAVE NOW FALLEN BACK BELOW FLOOD STAGE. PRECIPITATION THIS AFTERNOON WILL NOT BE HEAVY OR WIDESPREAD ENOUGH TO SIGNIFICANTLY REVERSE THE TREND OF FALLING WATER LEVELS. DO NOT FORESEE ANY SIGNIFICANT RAINFALL OVER THE NEXT SEVERAL DAYS WHICH SHOULD GIVE AREA RIVERS AND STREAMS AMPLE TIME TO SETTLE TO NORMAL LEVELS. && .OKX WATCHES/WARNINGS/ADVISORIES... CT...DENSE FOG ADVISORY...CTZ006>008-010>012...UNTIL 9AM SAT. NY...NONE. NJ...NONE. MARINE...SCA UNTIL 6 PM SUN FOR ANZ350-353-355. && NEAR TERM/AVIATION/HYDRO AND MARINE UPDATE...MALOIT
