NO SIGNIFICANT CHANGES TO THE FORECAST.
KEY MESSAGES

WEDNESDAY ALONG A COLD FRONTAL PASSAGE.

WARMING UP FRIDAY AND MORESO THIS COMING WEEKEND.
DISCUSSION
KEY MESSAGE 1)
A DIGGING UPPER LEVEL TROUGH WILL CROSS THE REGION WED MORNING.
AHEAD OF THIS, SURFACE LOW PRESSURE OVER LOWER MI WILL EXTEND A COLD
FRONT TO THE SOUTHWEST. SOUTHERLY FLOW AHEAD OF THIS FRONT WILL BRING
IN MORE MOIST AIR, ESPECIALLY ALONG A NARROW, SHORT- LIVED LLJET
AROUND 50KT. THE FRONT UNDERCUTS THE MOIST AIR AND A SW- NE ORIENTED
LINE OF SHOWERS AND THUNDERSTORMS ARE EXPECTED TO MOVE EAST THROUGH
THE REGION OVERNIGHT. THE ACTUAL FRONT WILL TAKE ITS TIME TO WORK
THROUGH THE REGION EARLY WEDNESDAY, POSSIBLY WITH SOME LINGERING
SHOWERS ALONG AND EAST OF THE SCIOTO RIVER THROUGH EARLY AFTERNOON.
BY DAYBREAK, THIS LINE SHOULD BE EAST OF THE I-71 CORRIDOR. AS THE
FRONT CROSSES, COOLER AIR IN CENTRAL OH MAY HOLD ON TO LINGERING
SHOWERS THROUGH THE MORNING, BUT DEEPER CONVECTION WILL HAVE MOVED
EAST. THE TRANSIENT LINE OF STORMS SHOULD NOT POSE ANY FLOODING RISK.
SHEAR PROFILES WEAKEN AS THE FRONT MOVES FROM IN INTO OH DURING A
TIME OF THE DIURNAL MINIMUM, DIMINISHING THE POTENTIAL FOR SEVERE
WEATHER FROM THIS LINE OF STORMS. MODELS ARE BULLISH PRODUCING
THUNDER FOR MUCH OF THE OVERNIGHT HOURS, BUT A WELL-DEFINED LINE
TELLS ME THAT AT LEAST SOME THUNDER WILL OCCUR THROUGHOUT ITS
PASSAGE.
KEY MESSAGE 2)
AFTER A WEAK COLD FRONT CROSSES TODAY, TEMPERATURES WILL BE MUTED
WITH HIGHS IN THE 60S. SOUTHERLY FLOW AHEAD OF THE NEXT, STRONGER
FRONT WILL SEE A SLIGHT BUMP TUESDAY WITH HIGHS IN THE 70S. THEN,
EXPECT A COOLDOWN FOR THE MIDDLE OF THE WEEK, FOLLOWED BY WARMER AIR
ON FRIDAY AND MORESO FOR THE COMING WEEKEND. TEMPS THIS COMING
WEEKEND SHOULD REACH INTO THE 80S.
AVIATION /12Z MONDAY THROUGH FRIDAY/
VERY LITTLE IF ANY VARIABILITY ACROSS THE TERMINALS FOR TODAY. 1-2
HOUR DIFFERENCES IN PRIMARY WIND DIRECTIONS AND THE OCCASION OF A
BKN VFR DECK IN THE AFTERNOON BREAKING UP IN THE LATE DAY/EARLY
EVENING ARE HARDLY WORTH THE MENTION. A WEAK SFC LOW SHOULD BE FOUND
ALONG THE OHIO RIVER TOWARDS EVENING, BRINGING CVG/LUK MORE OF A
VARIABLE DIRECTION VERSUS THE BACKING NE DIRECTION FOUND FOR THE
REMAINING TAF SITES DURING THIS TIME.
OUTLOOK...MVFR CEILINGS AND VISIBILITIES POSSIBLE TUESDAY NIGHT INTO
WEDNESDAY.
