NATIONAL WEATHER SERVICE BUFFALO NY
214 PM EDT MON MAY 11 2015
.SYNOPSIS...
A STALLED FRONTAL BOUNDARY WILL REMAIN NEAR THE AREA THROUGH TONIGHT

&&
.NEAR TERM /THROUGH TUESDAY/...
SEVERAL LINES OF CONVECTION FORMING THIS AFTERNOON...TWO WELL
INLAND ALONG SUBTLE BOUNDARIES TOWARD THE FINGER LAKES REGION BUT
WELL EAST OF ANY LAKE BOUNDARIES. A SINGLE CELL HAS FORMED ALONG
THE LAKE ERIE BOUNDARY NEAR 18Z. THESE LINES SHOULD CONTINUE TO
MOVE STEADILY EAST THIS AFTERNOON. WIND SHEAR IS MARGINAL FOR
SEVERE WEATHER WITH WINDS ALOFT NEAR 20-30KT.
AS THIS AREA OF CONVECTION MOVES EAST OF THE EASTERN LAKE ONTARIO
REGION AROUND OR BEFORE SUNSET...THE NEXT AREA OF CONVECTION
ASSOCIATED WITH A PREFRONTAL TROUGH AHEAD OF THE MAIN COLD FRONT
SHOULD BE QUICKLY APPROACHING THE REGION. TIMING FOR THIS EVENT
SHOULD BE DURING THE EVENING IN WESTERN NY...AND MIDNIGHT OR
SO/LATER EAST OF THE GENESEE VALLEY WITH STEADILY DECREASING
INTENSITY WITH TIME.
ON TUESDAY...THE DAY SHOULD START OFF DRY WITH COLD AIR ADVECTION
CONTINUING THROUGHOUT THE DAY. WITH LEFT OVER MOISTURE AND JUST
ENOUGH JUST ENOUGH INSTABILITY IN THE AFTERNOON...SOME BRIEF LOW
TOPPED SHOWERS MAY DEVELOP ALONG LAKE BREEZE BOUNDARIES...BUT
THESE WILL BE SHORT-LIVED WITH MOSTLY TRACE AMOUNTS.
THE MAIN CONCERN WILL BE WINDS. LOW LEVEL WINDS SHOULD EASILY MIX
DOWN ALONG THE LAKE PLAINS...WITH GUSTS TO 50MPH IN THE AFTERNOON.

THE STRONG MAY SUNSHINE. WINDS SHOULD SLACKEN WITH ANOTHER CHANCE
OF INLAND DIURNAL SHOWERS IF ENOUGH SYNOPTIC MOISTURE REMAINS.
TEMPERATURES WEDNESDAY NIGHT WILL SLIP INTO THE 30S AND LOW 40S SO
FROST MAY BECOME A CONCERN WITH CLEAR SKIES AND LIGHT
