AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BINGHAMTON NY 804 PM EDT THU MAR 20 2014 .SYNOPSIS... LAKE EFFECT SNOW SHOWERS WILL MOVE THROUGH NORTHERN NY OVERNIGHT, THEN ANOTHER STORM SYSTEM WILL CROSS THE GREAT LAKES FRIDAY NIGHT INTO SATURDAY. THIS STORM WILL BRING A WINTRY MIX OF LIGHT PRECIPITATION. && .NEAR TERM /THROUGH FRIDAY/... UPGRADED POPS THROUGH THE LATE AFTERNOON TO ACCOUNT FOR STRONGER THAN EXPECTED THERMALS PRODUCING BRIEF SQUALLS. TEMPERATURES WILL REMAIN HIGHLY VARIABLE, FLUCTUATING BETWEEN THE UPPER 30S AND UPPER 40S BASED ON SUNSHINE AND PRECIPITATION. A LAKE BAND WILL SET UP MAINLY NORTH OF OUR FA OVERNIGHT. THE PERIPHERY COULD BRING 2 TO 3 INCHES OF NEW SNOW TO FAR NORTHERN ONEIDA COUNTY, AND LIGHTER AMOUNTS ACROSS THE NORTHERN FA. && .SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/... 800 PM EDT UPDATE... SCATTERED LAKE EFFECT SNOW SHOWERS CONTINUE ACROSS THE CWA THIS EVENING. EXPECT THESE TO SLOWLY DIMINISH TOWARDS SUNRISE TOMORROW. MADE MINOR ADJUSTMENTS TO THE FORECAST ON TEMPS TO ADJUST TO REALITY. PREVIOUS FORECAST LOOKS GOOD. PREVIOUS FORECAST... BRIEF HIGH PRESSURE BUILDS IN FRIDAY MORNING, BEFORE A CYCLONE TREKS ACROSS THE GREAT LAKES TO NEAR LAKE ONTARIO LATE FRIDAY NIGHT. UTILIZED THICKNESS TOOL, COMBINED WITH MODEL SOUNDING ANALYSES, AND CAME UP WITH A MAINLY RAIN TO SNOW MIX, AND SOME BRIEF EMBEDDED FREEZING RAIN. THE KEY WITH THIS SYSTEM IS THAT MOISTURE IS VERY LIMITED. THEREFOR BELIEVE THE EFFECTS OF THE WINTRY MIX WILL BE MINIMAL, AND SNOW TOTALS WILL BE WELL UNDER AN INCH. LAKE EFFECT WILL SET UP BRIEFLY BEHIND THE CYCLONE BEFORE A BUILDING RIDGE SHEARS THE LOW LEVEL WIND PROFILE. ANOTHER ARCTIC SHOT MOVES INTO ONTARIO PROVINCE, WITH COLD AIR BLEEDING INTO NY/PA AND BRINGING MUCH BELOW NORMAL TEMPS FOR SUNDAY. && .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... EXTENDED PERIOD WILL BE DOMINATED BY AN UPPER LEVEL TROF THAT WILL EXTEND OVER EASTERN CANADA AND THE EASTERN UNITED STATES. TEMPERATURES MONDAY THROUGH WEDNESDAY WILL RUN ABOUT 15 DEGREES BELOW NORMAL. LATE IN THE PERIOD THERE ARE SIGNS OF H5 HEIGHTS RISING AS JAMES BAY VORTEX STARTS LIFTING NORTH RESULTING IN SOME MODIFICATION ON THURSDAY. SUNDAY NIGHT, COLD NORTHWEST FLOW MAY PRODUCE SOME SCATTERED LAKE EFFECT SNOW SHOWERS PRIMARILY IN THE FINGER LAKES REGION. MONDAY THROUGH MONDAY NIGHT, LOOKS DRY WITH SFC HIGH PRES IN VCNTY. TUESDAY THROUGH TUESDAY NIGHT, WILL CONTINUE WITH CHC POPS AS MODELS SHOW SFC LOW PRES TRACKING FROM THE CAROLINAS NORTHEAST TO COASTAL NEW ENGLAND. AREA MAY GET BRUSHED BY THIS SYSTEM BUT FOR NOW THE BRUNT OF SENSIBLE WEATHER ASSOCIATED WITH COASTAL WILL BE WELL EAST OF FA. BEHIND FEATURE ON WEDNESDAY MORE LAKE EFFECT SNOW SHOWERS ARE POSSIBLE UNDER COLD NORTHWEST FLOW. THURSDAY WITH SFC HIGH PRES IN THE MID ATLANTIC, DRY AND MILDER WEATHER IS EXPECTED. && .AVIATION /00Z FRIDAY THROUGH TUESDAY/... KBGM RADAR SHOWS WIND FROM AROUND A 270-280 DEGREES ABT 25 KTS JUST OFF THE DECK TO 50 KNOTS AT AROUND 12 KFT. THE FLOW WILL GRADUALLY VEER MORE TO ARND 280-290 DEGREES BY 6Z OR SO AS AN UPPER LEVEL WAVE TRACKS E-SE ACRS THE REGION BY 6Z. THIS WILL INCREASE THE MOISTURE AND LAKE ENHANCED SNOW SHOWERS FOR THE REST OF THE C NY TERMINALS BY 6Z EXCEPT KRME. FOR KRME I EXPECT IFR TO LIFR BTWN 00Z AND 02Z AND THEN IFR-MVFR BETWEEN 2Z AND 6Z...THEN PATCHY MVFR SHSN BTWN 6 AND 10Z. AT KSYR I EXPECT VFR TO IFR IN SHSN 00Z TO 04Z AND MVFR-IFR SNSH BTWN 04Z AND 06Z AS MOISTURE PEAKS. FARTHER S...I THINK THE VSBYS WILL DROP TO IFR A BIT LATER WITH THE VEERING FLOW AS THIS WAVE PASSES. SO FOR KITH I HAVE A TEMPO IFR GROUP FOR SHSN BTWN 01Z AND 05Z AND 02Z AND 06Z AT KBGM. AT KELM...I HAVE MAINLY VFR WITH TEMPO FOR MVFR SHSN UNTIL 4Z. AS FOR KAVP I SEE JUST VFR IN MAINLY BKN-OVC SC THRU THE NGT WITH A FEW FLURRIES UNTIL 4Z. AFTER THIS WAVE PASSES ARND 6Z...SUBSC WILL LOWER THE INVERSION AND I EXPECT MAINLY VFR IN BKN-OVC SC UNTIL LATE MORNING ALL TAFS. THE SC WILL CLR FIRST TO THE W AND S AT KELM AND KAVP AND LAST IN KRME AS SUBSDC AND HIGH PRESSURE BUILDS IN DURG THE DAY FRIDAY FROM SW-NE. WINDS WILL BE WEST AT 10-15 KNOTS WITH GUSTS AROUND 25 KNOTS OR SO THROUGH 6Z. THEN WINDS WILL BE WEST TO NORTHWEST AROUND 10 KNOTS THRU FRIDAY. OUTLOOK...
