DISCUSSION
KEY MESSAGE 1)
THE ONSET OF THE UPCOMING WARM PERIOD HAS BEGUN THIS AFTERNOON WITH
MID TO UPPER 70S AND LOWER 80S OBSERVED ACROSS THE AREA. OVERNIGHT, A
WEAK SYSTEM QUICKLY MOVES INTO THE AREA. STRONG LOW LEVEL WINDS
PRESENT AN OPPORTUNITY FOR STRONG WIND GUSTS BEFORE DAYBREAK, BUT
THIS WILL BE DEPENDENT ON IF THE WINDS CAN REACH THE SURFACE. THIS
WEAK SYSTEM MOVING THROUGH THE LOWER GREAT LAKES INTERRUPTS THE
SUNSHINE ON MONDAY, WITH SCATTERED SHOWERS AND A FEW THUNDERSTORMS
POSSIBLE DURING THE MORNING AND EARLY AFTERNOON HOURS.
THEN, THE MID-LEVEL RIDGE BECOMES MORE ESTABLISHED INTO MID-WEEK AS A FEW
WEAK DISTURBANCES RESULT IN INCREASED CHANCES FOR SHOWERS AND
THUNDERSTORMS PRIMARILY NORTHWEST OF THE LOCAL AREA. GIVEN SOME OF
THE UNCERTAINTY, NBM POPS WERE A BIT HIGHER THAN DESIRED AND WERE
THEREFORE LOWERED AFTER COLLABORATION WITH SURROUNDING OFFICES NORTH
OF THE AREA.
DESPITE THE LOWER POTENTIAL FOR WIDESPREAD RAINFALL, SOUTHWESTERLY
FLOW CONTINUES TO SUPPORT WARM AND MOIST SOUTHWESTERLY FLOW.
HOWEVER, A MOIST AND WARM SOUTHWESTERLY FLOW WILL SUPPORT SCATTERED
SHOWER AND THUNDERSTORM DEVELOPMENT DURING THE AFTERNOON AND EVENING
HOURS. WEDNESDAY NIGHT INTO THURSDAY IS WHEN THE BETTER CHANCE FOR
SHOWERS AND THUNDERSTORMS ARRIVES, DUE TO A STRONG TROUGH MOVING
THROUGH THE GREAT LAKES.
THE MID-LEVEL RIDGE QUICKLY BUILDS BACK INTO PLACE, WITH ATTENTION
SHIFTING TO A STRONGER COLD FRONT SET TO MOVE THROUGH NEXT WEEKEND.
AVIATION /18Z SUNDAY THROUGH FRIDAY/
PREVAILING VFR CONDITIONS THROUGH THE REST OF THE AFTERNOON AND
EVENING WITH GUSTS RANGING FROM 20 TO 25 KNOTS. A PERIOD OF LLWS
DEVELOPS DURING THE OVERNIGHT AS A SYSTEM APPROACHES THE AREA.
CHANCES FOR SHOWERS INCREASE AFTER 06Z, BUT MAINTAINED THE PROB30
THRESHOLDS GIVEN THE LACK OF COVERAGE. THUNDERSTORM CHANCES ALSO
REMAIN QUITE LOW. MVFR CIGS WILL ACCOMPANY PERIODS OF RAIN SHOWERS.
AS THE SYSTEM MOVES THROUGH TOWARD 12Z, THERE IS SOME POTENTIAL FOR
STRONGER WINDS. FOR NOW, WIND GUSTS IN THE 20 TO 25 KNOT RANGE ARE
ADVERTISED, HOWEVER, SOME STRONGER WIND GUSTS OVER 30 KNOTS CANNOT BE
RULED OUT.
THE BETTER CHANCE FOR MORE FREQUENT WIND GUSTS NEAR 30 KNOTS ARRIVES
AFTER 13Z, BECOMING LESS FREQUENT AND LOWER IN STRENGTH TOWARD THE
END OF THE TAF PERIOD.
OUTLOOK...MVFR CONDITIONS AND THUNDERSTORMS POSSIBLE AT TIMES MONDAY
THROUGH WEDNESDAY.
