AUGUST 2019 DID NOT FEATURE ANY EXTREME TEMPERATURES, BUT RATHER A NEAR NORMAL TEMPERATURE MONTH WITH OCCASIONAL WARM AND COOL SPELLS. THERE WERE A FEW HEAVY THUNDERSTORMS THAT PASSED ACROSS THE METRO AREA DURING THE MORNING HOURS...WITH ENOUGH RAIN IN TOTAL FOR THE MONTH TO MAINTAIN GOOD GROWTH ON SUMMER VEGETATION. THE TEMPERATURE AVERAGED 70.3F THIS MONTH WHICH IS ABOUT A HALF A DEGREE ABOVE NORMAL. THERE WERE JUST 6 DAYS THAT STRAYED 5 OR MORE DEGREES FROM NORMAL. THERE WERE 20 DAYS THAT FINISHED ABOVE TEMPERATURE NORMALS, AND 9 THAT FINISHED BELOW NORMAL. THE HIGHEST TEMPERATURE WAS 85F DEGREES THIS MONTH, OCCURING ON BOTH THE 2ND, 5TH AND 6TH. PRECIPITATION WAS 3.62 INCHES FOR AUGUST WHICH IS ABOUT A THIRD OF AN INCH ABOVE NORMAL. THERE WERE 3 DAYS THAT HAD OVER A HALF INCH OF RAINFALL FOR THE MONTH. THE FIRST OCCURRED ON THE 13TH WHEN OVER AN INCH OF RAIN FELL IN AN HOUR (BETWEEN 5 AND 6 AM)...BRINGING THE TOTAL FOR THE DAY TO 1.22 INCHES. LATE MORNING THUNDERSTORMS ON THE 17TH HELPED TO BRING A DAILY TOTAL OF 0.57 INCHES, WHILE EARLY MORNING THUNDERSTORMS ON THE 21ST BROUGHT THE DAILY TOTAL TO 0.74 INCHES. OVERALL THERE WERE 10 DAYS WITH MEASURABLE RAIN, EXACTLY NORMAL FOR THE MONTH. AUGUST STARTED PLEASANT ACROSS WESTERN NEW YORK, WITH HIGH PRESSURE BRINGING COMFORTABLE LEVELS OF HUMIDITY TO GO ALONG WITH SUMMER`S WARMTH. THERE WAS VERY LITTLE WEATHER OF INTEREST THE FIRST WEEK OF THE MONTH. ON THE 8TH, A WIDESPREAD SEVERE THUNDERSTORM EVENT STARTED EARLY, WITH DAMAGING WINDS REACHING THE LAKE ERIE SHORELINE BY LATE MORNING. THESE THUNDERSTORMS, WITH DAMAGING WINDS, REACHED THE GENESEE VALLEY BY THE NOONTIME HOUR. BEHIND THIS EVENT, A COOLER AIRMASS SETTLED ACROSS WESTERN NEW YORK WITH A RETURN TO LOWER HUMIDITY VALUES AND OVERNIGHT LOWS DIPPING INTO THE LOW TO MID 50S ON THE 10TH-11TH. THOUGH NOT SEVERE, HEAVY DOWNPOURS OF RAIN PUSHED ACROSS BUFFALO ON THE 13TH, DROPPING OVER AN INCH OF RAINFALL DURING THE EARLY MORNING HOURS. THERE WAS VERY LITTLE IMPACT FROM THIS HEAVY RAIN EVENT. ON THE 15TH OF THE MONTH A STRETCH OF DAILY SEVERE WEATHER BEGAN ACROSS WESTERN NEW YORK...WITH MULTIPLE SEVERE THUNDERSTORMS EACH AFTERNOON AND EVENING THROUGH THE 18TH. AN UPPER LEVEL TROUGH WAS FOUND OVER THE GREAT LAKES THIS PERIOD, WITH MULTIPLE SHORTWAVES FORCING AFTERNOON AND EVENING CONVECTION ACROSS WESTERN NEW YORK. STORMS ON THE 15TH WERE FOCUSED MORE TOWARDS THE GENESEE VALLEY WHILE ON THE 16TH AND 17TH THE PRIMARY FOCUS FOR SEVERE STORMS WAS UPON A LAKE BREEZE BOUNDARY TO THE NORTH AND EAST OF BUFFALO AND SOUTH OF LAKE ONTARIO. STORMS ON THE 18TH FEATURED A VIVID LIGHTNING DISPLAY AND RAINS NEAR BUFFALO DURING THE SUNRISE PERIOD...AND LATER IN THE DAY DAMAGING CONVECTIVE WIND GUSTS AS WELL AS FLOODING RAINS IN THE GENESEE VALLEY AND FINGER LAKES REGION. ON THE EARLY MORNING OF THE 21ST A SLOW MOVING COMPLEX OF THUNDERSTORMS ROLLED THROUGH BUFFALO, ESPECIALLY THE NORTHTOWNS WHERE SEVERAL INCHES OF RAIN FELL. HARDEST HIT WAS KENMORE WHERE 2 TO 3 INCHES OF RAIN FLOODED NUMEROUS ROADS AND CREATED HAVOC FOR THE MORNING COMMUTE. BY THE 22ND THE WEATHER FINALLY QUIETED DOWN AND ANOTHER PLEASANT STRETCH WITH COOL, BUT COMFORTABLE SUMMER TEMPERATURES ENSUED WITH LOW LEVELS OF HUMIDITY. OVER NIGHT LOWS DIPPED INTO THE LOWER 50S SEVERAL DAYS...HINTING AT A TOUCH OF FALL IN THE AIR. THE END OF THE MONTH FEATURED NEAR NORMAL TEMPERATURES AND A FEW DAYS OF LIGHT RAIN AND MODERATE LEVELS OF HUMIDITY. LAKE ERIE PEAKED AT 75F DEGREES EARLY IN AUGUST, 2 DEGREES ABOVE THE NORMAL PEAK SUMMER TEMPERATURE. WINDS WERE NORMAL FOR THE MONTH AND THE STRONGEST GUST THIS MONTH OCCURRED ON THE 6TH WHEN WINDS GUSTED TO 39 MPH AS A COLD FRONT MOVED THROUGH THE REGION. IN ALL A FAIRLY TYPICAL AUGUST, WITH SEVERAL BOUTS OF SEVERE STORMS AND NO EXTREMES IN TEMPERATURE. && THOMAS $$
