DISCUSSION
KEY MESSAGE 1...SHOWERS AND THUNDERSTORMS POSSIBLE TODAY, SOME OF
WHICH MAY PRODUCE STRONG GUSTY WINDS AND HEAVY RAINFALL.
THE POTENTIAL FOR SHOWERS AND THUNDERSTORMS WILL INCREASE TODAY AS
THE LOW OVER THE NORTHERN ONTARIO PROVINCE DIRECTS A COLD FRONT
TOWARDS THE LOWER LAKES.
SEVERE WEATHER AND EXCESSIVE RAINFALL POTENTIAL...
LITTLE OVERALL CHANGE WITH PREVIOUS THINKING AS GUIDANCE STILL SHOWS
A LOW CAPE/HIGH SHEAR (+40) ENVIRONMENT. IT STILL LOOKS LIKE SOME
MEASURE OF SHOWERS OR STORMS DEVELOP OUT AHEAD OF THE APPROACHING
STRONG COLD FRONT AROUND 15Z. AFTER THAT...A LINE OF STORMS IS
ADVERTISED TO THEN COMES MARCHING IN BETWEEN 18Z-21Z THIS AFTERNOON
WITH THE FRONT. CAPE VALUES STILL ARE 'NOT' ALL THAT IMPRESSIVE WITH
BETWEEN 900-1200 J/KG AWAY FROM THE LAKES. SPEAKING OF WHICH, IT
REMAINS TO BE SEEN HOW MUCH THE LAKES WILL EVEN INFLUENCING THE
EVOLUTION OF CONVECTION. EVEN SO...GIVEN THE DECENT SHEAR
STORMS WILL HAVE THE POTENTIAL TO BECOME STRONG TO SEVERE WITH
THE PRIMARY RISK DAMAGING WIND GUSTS. SPC HAS CONTINUED TO
HIGHLIGHT OUR REGION IN A MARGINAL-SLIGHT RISK FOR SEVERE
STORMS. ADDITIONALLY...PWATS WILL BE FOUND IN THE 1.5-1.75"
RANGE AHEAD OF THE COLD FRONT. THE MAIN CONCERN WOULD BE IF
STORMS WERE TO TRAIN OVER THE SAME LOCATION. THERE CONTINUES TO
BE A MARGINAL RISK FOR EXCESSIVE RAINFALL, WITH AN EXPANSION OF
THE SLIGHT RISK ACROSS JEFFERSON AND FAR NORTHERN LEWIS COUNTY.
KEY MESSAGE 2...DRY WEATHER RETURNS MONDAY AND NOTABLY COOLER.
SHOWERS AND STORMS WILL END FROM NW TO SE SUNDAY NIGHT BEHIND THE
FRONT, WITH A MUCH COOLER AIR MASS SPILLING IN ACROSS THE LOWER
LAKES. WITH HIGH PRESSURE BUILDING IN MONDAY EXPECT DRY WEATHER BUT
COOL CONDITIONS AS H850 T'S DIP INTO THE SINGLE DIGITS.
AVIATION /06Z SUNDAY THROUGH THURSDAY/
VFR CONDITIONS WILL CONTINUE THROUGH 12Z THIS MORNING. SHOWERS AND
THUNDERSTORMS WILL BE POSSIBLE TODAY AS A COLD FRONT NEARS AND THEN
CROSSES THE REGION. THESE SHOWERS AND THUNDERSTORMS WILL BRING ABOUT
LOCALIZED IFR-LIFR CONDITIONS AT TIMES TO AREA TERMINALS.
WITH THE PASSAGE OF THE FRONT LINGERING MVFR-IFR CIGS WILL BEGIN TO
SLOWLY IMPROVE SUNDAY NIGHT, WITH A RETURN TO VFR OVERNIGHT.
OUTLOOK...
MONDAY...VFR.
TUESDAY...MAINLY VFR. A SLIGHT CHANCE OF A SHOWER OR THUNDERSTORM.
WEDNESDAY AND THURSDAY...MAINLY VFR. INCREASING CHANCES FOR SHOWERS
AND THUNDERSTORMS.
MARINE
ELEVATED SOUTHWEST WINDS AHEAD OF A COLD FRONT WILL MAKE FOR
CHOPPY CONDITIONS ON AREA LAKES. SHOWERS AND THUNDERSTORMS WILL
BE POSSIBLE AHEAD AND ALONG OF THE APPROACHING COLD FRONT, SOME
OF WHICH MAY PRODUCE STRONG GUSTY WINDS AND HIGHER WAVE ACTION.
WINDS WILL TURN WESTERLY BEHIND THE COLD FRONT THIS EVENING AND
TONIGHT, WHICH MAY BRING A BRIEF PERIOD OF SMALL CRAFT
CONDITIONS TO THE LAKES. LIGHTER WINDS AND WAVE ACTIONS EXPECTED
MONDAY AS HIGH PRESSURE BUILDS OVER THE LOWER LAKES.
