Area forecast discussion, May 12, 4:00 PM EDT, 2 hours 29 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GAYLORD MI
400 PM EDT FRI MAY 12 2000

ACTIVE AFTERNOON ACROSS MI WITH TOR WATCH STILL IN TACT THRU 6
PM...WITH ANOTHER TOR WATCH TO THE W OVER ERN WI. ELEVATED
CONVECTION CONTINUES TO FIRE N OF THE SFC LOW AND WARM FRONT IN ERN
WI AND LOWER MI IN AND CLOSE TO THE WATCH BOXES. SHORT TERM CONCERNS
ARE TIMING THE END OF CONVECTION TONIGHT. ATTENTION THEN TURNS TO
POPS AND TEMPS THRU SUNDAY ON THE BACKSIDE OF THE SFC SYSTEM.

MODELS INITIALIZED WELL WITH RESPECT TO THE REMNANTS OF THE MCS OVER
FAR SE LOWER MI AT 12Z THIS AM. ETA AND AVN THEN DO A GOOD JOB OF
CARRYING THIS ENERGY INTO WRN NY...BUT NGM WEAKENS THE UPPER SUPPORT
FOR THE MCS TOO QUICKLY. ETA ALSO SEEMS TO HAVE PROGGED THE
DEVELOPMENT OF THE CONVECTION OVER WI BETTER THAN THE NGM...AND HAS
THUS FAR MATCHED WELL WITH REALITY...TAKING THE UPPER SUPPORT AND
SFC MOISTURE CONVERGENCE INTO CENTRAL LOWER MI THIS AFTERNOON.

TONIGHT...EXPECT CONVECTION WILL CONTINUE THRU AT LEAST THE EVENING
AND LIKELY NOT END ACROSS ERN UPR AND NE LOWER MI UNTIL AROUND 2 AM
AS THE SFC LOW REACHES LAKE HURON BY 06Z. HIGH THETA E AIR WILL
CONTINUE TO ADVECT INTO SRN SECTIONS OF THE CWA...WITH MUCAPES
REMAINING AROUND 2000 J/KG. STRONG 75 KT 500 MB JET MAX PUNCHING
INTO WI AND WRN LOWER MI...500-300 MB DIVERGENCE AND GOOD SPEED
SHEAR THRU THE COLUMN WILL CONTINUE TO PROVIDE UPPER SUPPORTED
NEEDED TO SUSTAIN ORGANIZED CONVECTION. WITH LITTLE DIRECTIONAL
SHEAR...WILL HAVE TO WATCH FOR TRAINING ECHOES AND THUS POSSIBLE
FLOODING LATER IN THE EVENING.

SATURDAY...GOOD CYCLONIC FLOW THRU THE COLUMN...WRAP-AROUND MOISTURE
ON THE BACKSIDE OF THE SYSTEM AND AN ELONGATED VORT MAX BEHIND THE
COLD FRONT WILL PROVIDE ENOUGH SUPPORT FOR GENERATION OF SCT SHRA
FOR THE ENTIRE CWA. CAA WILL TAKE PLACE FROM THE SFC THRU 700 MB AND
WITH LITTLE SOLAR HEATING TO DESTABLIZE LOW LEVELS...DO NOT EXPECT
THUNDER TO DEVELOP. TIGHT GRADIENT ON THE BACKSIDE OF THE STRONG LOW
AND 850 MB WINDS PROGGED TO BE AROUND 40 KTS WILL LIKELY INCREASE
SFC WINDS TO 20 TO 30 MPH IN THE AFTERNOON. WILL WORD ACCORDINGLY.

SATURDAY NIGHT AND SUNDAY...UPPER TROFF REMAINS IN PLACE ACROSS THE
GREAT LAKES. WEAK SHOTS OF ENERY WILL CONTINUE TO DROP SE THRU THE
UPPER TROFF...CYCLONIC FLOW AND SFC THRU 700 MB RH REMAINING AROUND
80 PCT WILL CONTINUE TO GENERATE SCT SHRA. WILL KEEP CHANCE POPS AND
COOL TEMPS (BELOW FWC GUIDANCE) IN THE FORECAST THRU SUNDAY.

EXTENDED FORECAST...MRF...ECMWF AND UKMET ARE ALL VERY SIMILAR IN
OVERALL LONG WAVE PATTERN THRU THU OF NEXT WEEK...THEN DIVERGE A BIT
IN SPEED OF THE CUT OFF SW UPPER LOW AS IT GETS EJECTED OUT OF THE
SW US TOWARD THE CENTRAL PLAINS ON FRIDAY. UKMET IS THE FASTEST...
ECMWF THE SLOWEST WITH THE MRF FALLING IN BETWEEN. CANADIAN IS THE
ODD MODEL OUT...KEEPING THE UPPER WAVE OPEN AND DRIVING IT QUICKLY E
INTO THE UPPER MISSISSIPPI VALLEY BY FRI. TENDING TO BUY THE MORE
AMPLIFIED...SLOWER SOLUTIONS. UPPER LOW REMAINS NEARLY STATIONARY
OVER THE NE US THRU TUE. A SERIES OF SHORT WAVES WILL ROTATE AROUND
THE UPPER TROFF...KEEPING A CHANCE OF PRECIP IN THE FORECAST THROUGH
TUE AND HOLDING TEMPS SOME 10 DEGREES BELOW NORMAL. CRITICAL
THICKNESSES AND 850 TEMPS DROPPING TO AROUND -5 C SUGGEST THE
POSSIBLITY OF FROZEN PRECIP MAINLY ACROSS ERN UPR MI SUNDAY
NIGHT...SO WILL HAVE TO BREAK DOWN AND MENTION THE S-WORD. SW LOW
FINALLY PUSHES NE INTO THE CENTRAL ROCKIES...KICKING AN UPPER RIDGE
TOWARD THE WRN GREAT LAKES AND BRINGING TEMPS BACK UP TO NORMAL FOR
THE LAST HALF OF THE WORK WEEK.

.APX...TORNADO WATCH MIZ025>036-041-042-LMZ345-LHZ362 TIL 6 PM EDT.
