...FLASH FLOOD WARNING CONTINUES UNTIL 4 AM EDT FOR LENAWEE AND 
MONROE COUNTIES...


AT 1250 AM EDT...NATIONAL WEATHER SERVICE DOPPLER RADAR INDICATED
SCATTERED LIGHT TO MODERATE SHOWERS MOVING THROUGH MOST OF THE 
DETROIT METROPOLITAN AREA. THE THREAT OF FLASH FLOODING HAS CEASED 
FOR THE TIME BEING. ALTHOUGH SOME AREAS MAY STILL BE EXPERIENCING 
LOCAL FLOODING.

HEAVIER SHOWERS AND THUNDERSTORMS CONTINUE TO MOVE EAST ACROSS 
LENAWEE AND MONROE COUNTIES.  THESE STORMS COULD STILL PRODUCE FLASH 
FLOODING THROUGH 4 AM. 

ANOTHER THUNDERSTORM COMPLEX OVER WISCONSIN WILL LIKELY AFFECT 
SOUTHEAST LOWER MICHIGAN AROUND SUNRISE.  THIS SYSTEM COULD 
AGGRAVATE EXISTING FLOODING OR PRODUCE NEW FLOODING ACROSS THE AREA.  
THEREFORE A FLOOD WATCH STILL REMAINS IN EFFECT.

BE ESPECIALLY CAUTIOUS AT NIGHT WHEN IT IS HARDER TO RECOGNIZE THE 
DANGERS OF FLASH FLOODING. IF FLASH FLOODING IS OBSERVED ACT 
QUICKLY. MOVE UP TO HIGHER GROUND TO ESCAPE FLOOD WATERS. DO NOT

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
815 PM EDT FRI MAY 21 2004

.UPDATE...
CONVECTIVE POTENTIAL RECOVERING RAPIDLY AT THE END OF DAYTIME
HEATING. STORMS DEVELOPING OVER SW LOWER FOCUSED ON THE SURFACE TROF
FROM ABOUT PORT HURON TO LANSING. MID LEVEL LAPSE RATES ARE MODEST
IN THE SAGINAW VALLEY AND THUMB BUT CLOSE TO 7.5 C/KM NEAR THE OHIO
BORDER, ENOUGH TO HELP SUSTAIN THE MCS AS IT MOVES THROUGH LOWER
MICHIGAN THIS EVENING. EXPECT CONVECTION TO BE NEAR SEVERE LIMITS
ALONG AND SOUTH OF THE SURFACE TROF/INTERSTATE 69 THROUGH THE
EVENING AND EARLY OVERNIGHT HOURS. RAIN WILL BE WIDESPREAD OVER THE
SAGINAW VALLEY BUT STORMS LESS INTENSE. STILL HAVE A SHOT AT A LATE
NIGHT ROUND OF STORMS AS CONVECTION CONTINUES TO FORM OVER IOWA.

FORECAST UPDATE WILL REFLECT A TREND TOWARD INCREASING AREAL
COVERAGE DURING THE EVENING. FLOOD WATCH MESSAGE WILL BE UPDATED TO
REFLECT LATEST CONVECTIVE TRENDS.

BT

.PREV DISCUSSION... ISSUED AT 300 PM TODAY
WE WILL EXTEND/HOIST FLOOD WATCH TO COVER ALL OF THE CWA THROUGH 6
PM SATURDAY (FOR NOW).  VERY ACTIVE WEATHER PERIOD SO THIS WILL BE
BRIEF.

SEVERE MCS/BOW ECHO PROGRESSING EAST WITH THE BOW APEX ACROSS
EXTREME SOUTHEAST LOWER MICHIGAN.  SEVERE WEATHER, FOR THE MOMENT,
WILL CLEAR THE REGION BY 20Z AS WE WILL BE ON THE SUBSIDENCE SIDE OF
THIS DEPARTING SYSTEM WITH RAIN GRADUALLY COMING TO AN END.  COLD
POOL ACROSS WISCONSIN HAS SENT THE OUTFLOW BOUNDARY ACROSS NORTHERN
ILLINOIS INTO CENTRAL IOWA.  NEW CONVECTION IS ALREADY DEVELOPING,
LIKELY INTO ANOTHER MCS, IN NORTHERN IOWA WHERE LOW LEVEL JET PER
PROFILERS IS FEEDING MOIST AIR NORTH ALONG THE BAROCLINIC BOUNDARY.
LATEST MODELS SUGGEST UPSTREAM MCS WILL TRACK INITIALLY NORTHEAST
THEN TURN EAST PER CORFIDI VECTORS AND THICKNESSES.  HOWEVER, THE
WARM FRONT WILL BE DISPLACED A BIT FURTHER SOUTH SO AT LEAST FOR NOW
THE THREAT FROM SEVERE WEATHER (HAIL/WIND) WILL BE LIMITED.  THE
MAIN CONCERN WILL BE FLOODING AS THE GROUND IS QUITE SATURATED AND
FLOOD GUIDANCE NUMBERS ARE LOWERING WITH TIME.

THE LOW LEVEL JET WILL STRENGTHEN OVERNIGHT (>50KTS) ACROSS THE
PLAINS AS TROF DIGS ACROSS THE ROCKIES.  THIS WILL BE SURE TO KEEP
ADDITIONAL THUNDERSTORMS DEVELOPING ALONG AND NORTH OF INTERSTATE 80
OVERNIGHT ACROSS THE PLAINS AND TRACK EAST ACROSS THE GREAT LAKES.
PWATS REMAIN WELL ABOVE 1.50 SO HEAVY RAINFALL A REAL CONCERN.

SEVERE WEATHER POTENTIAL PICKS UP ONCE AGAIN SATURDAY NIGHT INTO
SUNDAY AS IMPRESSIVE SURFACE WAVE DEEPENS A BIT AS IT TRACKS TOWARD
THE GREAT LAKES.  STRONG LOW LEVEL JET COMBINING WITH FRONTAL
BOUNDARY DRAPED ACROSS THE CWA COULD PROVE TO BE VERY INTERESTING.
EHI/S CLIMB OVER 2 WITH HELICITIES IN EXCESS OF 200
M2/S2...PRIMARILY ALONG AND NORTH OF INTERSTATE 69 WITH CAPES AROUND
2K J/KG.  OF COURSE, WITH ALL OF THIS CONVECTION IN THE MODELS, IT
WILL BE VERY DIFFICULT TO PIN DOWN FRONTAL PLACEMENT AND SEVERE
POTENTIAL.  WE ARE CERTAIN THAT WE WILL REMAIN IN THE MCS TRACK FOR
HEAVY RAINFALL AND FLOODING INTO THE WEEKEND.

LOOKS LIKE A BREAK ARRIVES FOR EARLY NEXT WEEK AS UPSTREAM TROF
RELOADS ACROSS THE PLAINS.  THIS WILL SEND ANOTHER COLD FRONT ACROSS
THE LAKES NEXT WEEK AS IT STILL LOOKS COOL AND WET FOR LATE WEEK
INTO THE HOLIDAY WEEKEND.
