Special Weather Statement, NWS Buffalo, NY

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BUFFALO NY
1148 AM EST SAT JAN 10 2015

.SYNOPSIS...
LAKE SNOWS WILL WEAKEN SOME TODAY BUT STILL CONTINUE EAST OF THE
LAKES BEFORE TAPERING OFF TONIGHT. HIGH PRESSURE WILL THEN BUILD
INTO THE REGION FOR THE END OF THE WEEKEND WITH DRY WEATHER AND
MORE SEASONABLE TEMPERATURES FOR SUNDAY. WEAK LOW PRESSURE WILL
BRING SOME LIGHT SNOW SUNDAY NIGHT AND MONDAY...WHICH WILL BE
FOLLOWED BY A PERIOD OF FAIR AND SEASONABLE WEATHER MID- WEEK.

&&

.NEAR TERM /THROUGH TONIGHT/...
REGIONAL RADARS SHOWING THE LAKE EFFECT SNOW PLUMES SHIFTING TO THE
NORTH OFF BOTH LAKES AS LOW LEVEL FLOW BACKS TO SOUTHWEST.

OFF LAKE ERIE...THE LAKE BAND HAS SHIFTED RATHER QUICKLY TO THE
NORTH THIS MORNING AND IS NOW PRIMARILY CONFINED TO NORTHERN ERIE
COUNTY...WITH THE HEAVIEST PORTION OF THE BAND FOCUS ON THE METRO
BUFFALO AREA. SNOWFALL RATES OF 1 TO 2 INCHES PER WILL OCCUR
WITHIN THIS BAND. LATEST MESO SCALE MODELS CONTINUING TO SUGGEST
THAT THE BAND WILL CONTINUE ITS STEADY NORTHWARD TREK AND WEAKEN
DURING THE COURSE OF THE AFTERNOON.

THE CURRENT MOVEMENT AND ORIENTATION OF THE BAND HAS ALLOWED THE
LAKE HEADLINES TO BE DROPPED FOR ALL AREAS...EXCEPT FOR NORTHERN
ERIE COUNTY...WHERE A LAKE EFFECT SNOW ADVISORY REMAINS IN THE
PLACE THROUGH THE AFTERNOON.

OFF LAKE ONTARIO...A STRONG LAKE EFFECT BAND REMAINS IN PLACE WITH
THE FOCUS OF THE HEAVIEST SNOW ACROSS THE WATERTOWN AREA AND THE
NORTHERN TUG HILL REGION. EQUILIBRIUM LEVELS STILL RATHER HIGH AT
AROUND 8K FEET. BEST LIFT ALSO CONTINUES TO LINE UP WELL WITH A
FAVORABLE DENDRITIC SNOW GROWTH ZONE. THIS SHOULD ALLOW THE LAKE
EFFECT BAND TO MAINTAIN SNOWFALL RATES OF UP TO 3 INCHES AN HOUR FOR
MOST OF THE DAY.

IN ADDITION TO THE LAKE SNOWS...GUSTY WINDS WILL CREATE BLOWING
SNOW ISSUES AND CONTINUE BITTER WINDS CHILLS BELOW ZERO THROUGH THE
AFTERNOON.

WARMER AIR ALOFT WILL CONTINUE TO MOVE IN TONIGHT FROM SW-NE. THIS
WILL BRING GENERAL CLOUDS AND PERHAPS A FLURRY BUT ALSO FINALLY
BRING AN END TO THE LAKE EFFECT SNOW.

&&

.SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/...
SUNDAY AN AREA OF HIGH PRESSURE WILL BE ANCHORED OVER THE SOUTHEAST
STATES...WITH SOUTHERLY FLOW ACROSS THE EASTERN GREAT LAKES REGION.
THIS FLOW WILL TAKE MORNING LAKE EFFECT SNOW SHOWERS OVER THE FAR
NORTHERN PORTIONS OF THE NORTH COUNTRY AND PUSH THEM INTO
CANADA...LEAVING OUR REGION DRY. A FEW BREAKS OF SUNSHINE IN THE
CLOUDS WILL AID IN AFTERNOON TEMPERATURES CLIMBING INTO THE MID TO
UPPER 20S.

LATER SUNDAY AND SUNDAY EVENING MOISTURE POOLING IN AN INVERTED
SURFACE TROUGH OVER THE LOWER MISSISSIPPI VALLEY WILL RISE
ISENTROPICALLY ACROSS THE OHIO VALLEY AND NORTHEAST...WITH A LIGHT
GENERAL SNOWFALL. SNOWFALL ACCUMULATIONS WILL BE LIGHT...WITH ONE TO
THREE INCHES FOR MUCH OF THE REGION...AND SLIGHTLY HIGHER TOTALS
ACROSS HIGHER ELEVATIONS OF SW NYS AND EAST OF LAKE ONTARIO WHERE
OROGRAPHIC UPLIFT SQUEEZES OUT AN EXTRA INCH OR SO OF SNOWFALL.

A COLD FRONT WILL THEN SWEEP ACROSS THE REGION MONDAY...PUSHED
EASTWARD BY A SHARP UPPER LEVEL SHORTWAVE. MOISTURE WILL LINGER
THROUGH THE DAY AND THIS WILL BRING OCCASIONAL SNOW SHOWERS...AGAIN
MAINLY ACROSS HIGHER ELEVATIONS. AS WINDS VEER AROUND TO NORTHERLY
BEHIND THIS COLD FRONT...A LIGHT NORTHERLY FLOW ACROSS LAKE ONTARIO
WILL LIKELY KEEP MULTI BANDED LIGHT LAKE EFFECT SNOW SHOWERS ALONG
THE SOUTHERN LAKE ONTARIO SHORELINE THROUGH MONDAY NIGHT.

A SHALLOW...BUT COLD AIRMASS FOLLOWING THIS COLD FRONT WILL BEGIN TO
LOWER AIR TEMPERATURES MONDAY AFTERNOON...AND THEN SEND TEMPERATURES
DOWN INTO THE SINGLE DIGITS MONDAY EVENING AND OVERNIGHT. ACROSS
INTERIOR SW NYS AND THE NORTH COUNTRY BELOW ZERO READINGS ARE
LIKELY...WITH POTENTIALLY NEGATIVE TEENS IN THE NORTH COUNTRY WITH
GOOD RADIATIONAL COOLING EFFECTS.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
SHALLOW COLD AIR MASS WILL SETTLE ACROSS THE REGION TUESDAY BEHIND
THE MONDAY NIGHT SHORTWAVE PASSAGE...WITH A SURFACE HIGH PRESSURE
CENTERED OVER UPSTATE NEW YORK BY TUESDAY AFTERNOON AND EVENING.
HAVE LOWERED TEMPERATURES CONSIDERABLY FOR TUESDAY / TUESDAY NIGHT
WITH THIS FORECAST UPDATE. HIGH TEMPERATURES ON TUESDAY MAY STRUGGLE
TO GET OUT OF THE SINGLE DIGITS...AND LOWS TEMPERATURES TUESDAY
NIGHT IN THE NORTH COUNTRY WILL LIKELY DIP INTO THE TEENS BELOW
ZERO. THIS CONSIDERABLE COOL DOWN ON TUESDAY WILL THANKFULLY BE
SHORT LIVED...AS HIGH TEMPERATURES CLIMB BACK TO AROUND THE FREEZING
MARK BY THE END OF THE WEEK. FROM TUESDAY ON...THE WEATHER WILL BE
FAIRLY QUIET WITH NOT MUCH TO SPEAK OF IN TERMS OF PRECIPITATION
CHANCES...AS BENIGN FLOW AND DRIER AIR REMAIN IN PLACE.

&&

.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
OUTSIDE OF LAKE EFFECT SNOW...EXPECT VFR CONDITIONS THROUGH THE
PERIOD. LAKE EFFECT BANDS OFF LAKE ERIE WILL MOVE NORTHWARD AND
BRING A PERIOD OF IFR OR LOWER CONDITIONS TO THE KBUF AIRFIELD
THROUGH 21Z. THIS BAND SHOULD DISSIPATE THIS EVENING...WITH VFR
CONDITIONS OVERNIGHT AT BUF/IAG/ROC/JHW.

A STRONGER BAND OF LAKE SNOW WILL IMPACT THE KART AIRFIELD THROUGH
THIS AFTERNOON. EXPECT MODERATE TO HEAVY SNOW IN THE LAKE EFFECT
BAND WITH VSBY 1/2SM OR LESS. CONDITIONS WILL IMPROVE LATE TONIGHT
AS THE BAND FINALLY WEAKENS AND LIFTS NORTH OF WATERTOWN.

OUTLOOK...
SUNDAY...MAINLY VFR WITH A CHANCE OF SNOW SHOWERS EAST OF LAKE
ONTARIO AND LOCAL MVFR.
MONDAY...MVFR WITH A CHANCE OF SNOW.
TUESDAY THROUGH THURSDAY...VFR.

&&

.MARINE...
WINDS ON THE LAKES WILL VARY TODAY DUE WITH CONVERGENT BANDS
EXPECTED DOWN EACH LAKE. STRONGEST WINDS SHOULD BE FROM THE WNW
AND LOCATED ACROSS NORTHERN (MAINLY CANADIAN) WATERS...WITH A
WEAKER SW FLOW SOUTH OF THE LAKE CONVERGENCE. THE BRISK FLOW WILL
DIMINISHING TONIGHT AND SUNDAY. LIGHTER WINDS SHOULD RESULT IN A BIT LESS
WAVE ACTION AND FREEZING SPRAY. LOOKING AHEAD...SEE A RELATIVELY
QUIET PERIOD FOR THE WEEK...WITH HIGH PRESSURE INFLUENCING OUR
WEATHER MID-WEEK.

...INTENSE LAKE EFFECT SNOW THIS MORNING...

AT 700 AM A BAND OF INTENSE LAKE EFFECT SNOW CONTINUES ACROSS THE
NORTH COUNTRY.

THE NORTHERN EDGE OF THIS SNOW BAND IS FROM NEAR STONY

THE SNOW BAND WAS ALONG THE SOUTHERN JEFFERSON COUNTY BORDER TO
WORTH...BARNES CORNERS AND NORTHERN LOWVILLE.

WITHIN THE SNOW BAND EXPECT SNOWFALL RATES UP TO 4 INCHES PER
HOUR...NEAR ZERO VISIBILITIES AND DEEP SNOW COVERED ROADS. THIS
WILL MAKE TRAVEL EXTREMELY DIFFICULT AND NEARLY IMPOSSIBLE THROUGH

VALLEY OF LEWIS COUNTY AND TOWARDS THE NORTHERN PORTION OF
LEWIS...THE SNOW BAND RAPIDLY WEAKENS WITH MUCH LIGHTER SNOWFALL
RATES.

GUSTY WESTERLY WINDS WILL CREATE BLOWING AND DRIFTING OF SNOW THIS

EXPECT THIS SNOW BAND TO SLOWLY LIFT NORTHWARD THROUGH THE MORNING
