AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
759 PM EDT SUN MAY 14 2006
.AVIATION...
ONCE AGAIN...THE LONG PREVAILING LOW PRESSURE CIRCULATION WITH ITS
ATTENDANT MOISTURE AND SHOWERS IS THE SYNOPTIC FEATURE OF INTEREST
THROUGH THE TAF PERIOD. MAIN AREA OF LATE AFTERNOON INTO EVENING
CONVECTION IS IN AREA OF LOW TO MID LEVEL THETA E RIDGE WHICH
PIVOTED IN FROM THE EAST. GIVEN RADAR TRENDS...THE DTX RADAR IS OUT
OF SERVICE FOR THE OVERNIGHT...HAVE MENTIONED THUNDER IN THE KDET
AND KDTW TAF SITES UNTIL 01Z. OTHERWISE...TAFS REFLECT NUMEROUS
SHOWER MENTION THIS EVENING...THEN DECREASING TREND THROUGH THE
OVERNIGHT AS DIURNAL BOOST WANES AND SYNOPTIC SCALE LIFT INCLUDING
OMEGA LIFT AND ISENTROPIC LIFT...AS AT 295K...ALSO WANES. SHOWERS
LIKELY TO PICK UP AGAIN BY MONDAY AFTERNOON AS LAPSE RATES STILL
QUITE ROBUST TO SUPPORT DIURNAL DEVELOPMENT. TAFS MOSTLY REFLECT
MVFR CONDITIONS THROUGH MONDAY. SOME IFR CEILINGS POSSIBLE LATE
TONIGHT AND MONDAY IN SOUTHERN TAF SITES...WHERE THE RAIN/MOISTENING
HAS BEEN MOST CONCENTRATED.
&&
.SHORT TERM...ISSUED 314 PM EDT SUN
ALTHOUGH SHOWERS HAVE KEPT TEMPERATURES DOWN IN THE MID TO UPPER
50S ACROSS THE SOUTH THIRD OF THE CWA THUS FAR...STILL EXPECTING
TO SEE ISOLATED TO SCATTERED THUNDERSTORMS ACROSS SOUTHEAST
MICHIGAN BY EARLY THIS EVENING. RADAR TRENDS FROM EASTERN OHIO
SHOWS INCREASING CONVECTIVE ACTIVITY ADVANCING TOWARD SOUTHEAST
MICHIGAN. GOOD 925-850 MB FGEN BAND SETS UP OVER THE SOUTH HALF OF
THE CWA THIS EVENING AS TROUGH AXIS OVER THE OHIO VALLEY BECOMES
MORE W TO E ORIENTATED. 12Z GFS INDICATING THE SHOWALTER INDEX
GOING BELOW ZERO AT 00Z ACROSS THE SOUTH HALF OF THE CWA. GOOD
LIFT AND MOISTURE ADVECTION SHOULD ASSURE WIDESPREAD SHOWERS
THROUGH MUCH OF THE NIGHT BEFORE SFC-850 MB TROUGH AXIS SLOWLY
SAGS SOUTH OVERNIGHT. LOOKING FOR ANOTHER QUARTER TO THREE
QUARTERS OF AN INCH QPF (ISOLATED 1 INCH)...ASSUMING MAIN BAND
SINKS SOUTH AS EXPECTED. OTHERWISE...WE WILL BE LOOKING AT ANOTHER
1 TO 2 INCH RAINFALL WHICH COULD CAUSE SOME MINOR FLOODING PROBLEMS.
6 HR FLOOD GUIDANCE FOR WAYNE/MONROE/LENAWEE COUNTIES IS BELOW 2
INCHES.
500 MB TROUGH AXIS TO BECOME POSITIVELY TILTED TOMORROW WITH THE
CENTER OF THE CIRCULATION MOVING INTO THE EASTERN OHIO VALLEY.
ADDITIONAL SHORTWAVES ROTATING INTO THE CENTRAL GREAT LAKES
FROM THE EAST SHOULD ASSURE ADDITIONAL SHOWERS (SCATTERED TO
NUMEROUS)...AS THE DEEPER MOISTURE (1000 TO 500 MB RH GREATER THAN
85 PERCENT) WILL LINGER ACROSS THE SOUTHEAST PART OF THE CWA.
NORTHEAST FLOW OFF OF LAKE HURON...SOLID OVERCAST...AND WEAK LOW
LEVEL COLD ADVECTION SHOULD KEEP MAXES BELOW 60 DEGREES FOR
THE MOST PART. INSTABILITY LOOKS TO BE CONSIDERABLY LESS TOMORROW.
NONE-THE-LESS...WILL LET THE ISOLATED/SLIGHT CHANCE WORDING CONTINUE
FOR NOW.
&&
.LONG TERM...MONDAY NIGHT THROUGH SUNDAY...ISSUED 314 PM EDT SUN
THE RESIDENT UPPER LOW WILL BE LOCATED OVER THE OH/PA BORDER MONDAY
NIGHT WITH EXCELLENT MODEL AGREEMENT ON THE LOCATION AND GOOD
AGREEMENT ON THE MOISTURE DISTRIBUTION OVER SE MICHIGAN. THE
ATLANTIC MOISTURE SUPPLY COMBINED WITH DEEP CYCLONIC FLOW REMAINS
WORTHY OF LIKELY POPS OVER MOST OF OUR AREA MONDAY NIGHT, OR AT
LEAST MONDAY EVENING. COVERAGE, DURATION, AND QPF WILL BE MODULATED
BY LOBES OF MID LEVEL ENERGY ROTATING AROUND THE NORTH FLANK OF THE
CIRCULATION. EXPECT THE TIMING AND STRENGTH OF THESE SMALLER
FEATURES TO CHANGE FROM RUN TO RUN IN THE MODELS BUT THE OVERALL
LARGE SCALE PATTERN IS LOCKED IN PRETTY GOOD. WITH THIS IN MIND,
PLAN TO KEEP THE RAIN PROSPECTS CONFINED TO CHANCE/SCATTERED ON
TUESDAY FOR A COUPLE OF REASONS. THE FIRST IS THAT EAST COAST LOW
DEVELOPMENT WILL TEND TO INTERCEPT SOME ATLANTIC MOISTURE AND KEEP
IT FROM MAKING THE TRIP THIS FAR WEST. IN ADDITION, UPPER SUPPORT
WILL BE REDUCED AS THE LOW BECOMES MORE ELONGATED WITH THE TROF AXIS
TO OUR SOUTH AND EAST. THESE DEVELOPMENTS WILL WORK AGAINST A
RESPECTABLE DIURNAL COMPONENT THAT WILL BE ABOUT THE ONLY POSITIVE
FACTOR FOR SCATTERED SHOWER COVERAGE.
THERE IS A CHANCE OF SHOWERS LINGERING INTO TUESDAY EVENING, UNTIL
DAYTIME HEATING WEARS OUT, FOLLOWED BY A CLEARING TREND OVERNIGHT.
THE CLEARING TREND WILL BE DUE TO A SHORT WAVE RIDGE THAT IS STILL
ON SCHEDULE TO MOVE QUICKLY THROUGH LOWER MICHIGAN ON WEDNESDAY.
THIS WILL BE IN ADVANCE OF ANOTHER WAVE DIVING THROUGH CENTRAL
CANADA AND INTO OUR AREA WEDNESDAY NIGHT. PREFER TO SIDE WITH THE
GFS SOLUTION FOR FORECAST DETAILS AS THE NAM HAS BEEN CATCHING UP ON
THE WAVE IN CENTRAL CANADA FOR THE LAST FEW RUNS. HOWEVER, TIMING IS
PRETTY CLOSE AMONG ALL THE 12Z MODELS AND SUPPORTS OUR NEXT SHOT OF
RAIN ARRIVING WEDNESDAY NIGHT AND THURSDAY.
THE LOW PRESSURE SYSTEM ON THURSDAY WILL MOVE THROUGH THE AREA AND
REINFORCE THE LONG WAVE TROF IN PLACE OVER THE EASTERN HALF OF NORTH
AMERICA. THIS WILL RETURN SE MICHIGAN TO A BELOW NORMAL TEMPERATURE
PATTERN BUT WITH INDICATIONS OF RELATIVELY DRY CONDITIONS OTHERWISE.
THE LATEST MODEL RUNS CONTINUE TO SHOW CONFLUENT NW FLOW ALOFT OVER
LOWER MICHIGAN WITH A NARROW RIDGE OF SURFACE HIGH PRESSURE SETTING
UP BY FRIDAY. IF THIS SOLUTION CAN HOLD, WE WILL BE ABLE TO CONTINUE
BACKING OFF ON THE CHANCE OF RAIN TOWARD THE END OF THIS WEEK AND
KEEP THINGS DRY THIS WEEKEND.
