AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
331 PM EDT THU MAY 25 2006

.SHORT TERM...TONIGHT AND FRIDAY

12Z RAOBS/WATER VAPOR LOOP SHOW AN UPPER LOW OVER WISCONSIN...WITH A
SHORTWAVE SWINGING AROUND IT THROUGH ILLINOIS. SURFACE ANALYSIS
SHOWS LOW OVER WISCONSIN...WITH A WARM FRONT EXTENDING INTO CENTRAL
LOWER AND A COLD FRONT DOWN ACROSS ILLINOIS. REGIONAL RADARS SHOW A
COUPLE AREAS OF CONVECTION DEVELOPING...ACROSS INDIANA/OHIO AND
FARTHER NORTH ACROSS LOWER MICHIGAN.

MORNING STRATUS HAS MIXED OUT ACROSS MUCH OF THE CWA...WITH
TEMPERATURES CLIMBING INTO THE MID/UPPER 70S AND DEWPOINTS HOLDING
IN THE LOW 60S. THIS HAS LED TO MIXED LAYER CAPES OF OVER 1500J/KG
ACROSS MUCH OF THE CWA...WITH RAPIDLY DECREASING CIN. SPECIAL 18Z
DTX SOUNDING SHOWS A DECENT LOW-LEVEL CAP IN PLACE...WITH A SURFACE
TEMP OF 82 OR SO NEEDED TO GET AROUND IT. AREAS ACROSS THE THUMB
HAVE RECEIVED THE MOST INSOLATION TODAY WITH UP TO CFS 81F...AND
WITH EXTRA PUSH ALONG THE WARM FRONT STORMS HAVE ALREADY DEVELOPED.
EXPECT THIS DEVELOPMENT TO CONTINUE...INITIALLY ALONG THE WARM FRONT
IN THE NORTH AND EVENTUALLY ALONG THE COLD FRONT MOVING IN FROM THE
WEST. THEREFORE WILL STICK WITH NUMEROUS TSRA THROUGH MID EVENING...
THEN WITH SHOWERS CONTINUING OVERNIGHT BUT THUNDER POTENTIAL
DIMINISHING BEHIND THE COLD FRONT. WHILE THE BEST DEEP LAYER SHEAR
WILL BE SOUTH OF THE CWA WITH THE THE CORE OF THE MID-LEVEL JET
PASSING THROUGH THE OHIO VALLEY... THERE IS PRETTY GOOD LOW-LEVEL
SHEAR/HELICITY WITH A BACKED SOUTHEASTERLY SURFACE FLOW ACROSS
PORTIONS OF THE CWA. THEREFORE THERE IS A TORNADO POTENTIAL IN
ADDITION TO WIND/HAIL WITH STORMS THAT DEVELOP.

&&

.LONG TERM...FRIDAY NIGHT THROUGH THURSDAY

SUMMER LIKE CONDITIONS STILL ON TAP FOR THE LABOR DAY WEEKEND WITH
GFS/NAM/ECMWF ALL IN GENERAL AGREEMENT WITH POSITION AND STRENGTH OF
BUILDING RIDGE OVER THE EASTERN U.S. AND GREAT LAKES REGION. AT THIS
TIME WILL REMOVE MENTION OF LINGERING SHOWERS FRIDAY EVENING AS
STABILIZING NORTH FLOW...SUBSIDENCE AND DRYING MID LEVELS PLUNGING
THROUGH THE CWA BY 00Z SATURDAY.

RIDGE AXIS TO RAPIDLY AMPLIFY SATURDAY AND SUNDAY AS STRONG TROF
DIGS INTO THE PACIFIC NORTHWEST. THIS WILL RESULT IN 850 MB TEMPS
WARMING TO 18C BY SUNDAY AND SOUTHERN EDGE OF THE WESTERLIES WORKING
NORTH OF LAKE SUPERIOR. AS A RESULT ANTICIPATE MCS DEVELOPMENT AND
CONVECTION TO REMAIN NORTH AND WEST OF THE REGION AS WELL. STILL
ANTICIPATE DRY CONDTIONS THROUGH MONDAY WITH TEMPS IN THE MID 80S
THROUGH MONDAY AS WELL. COULD SEE SOME ISOLATED CONVECTION ON MONDAY
AFTERNOON AS MODELS DIMINISH STRENGTH OF MID LEVEL CAP...BUT BELIEVE
MODELS ARE UNDER DONE. STRENGTH OF CAP WILL DEPEND SOMEWHAT ON
POSITION OF TRAPPED/CLOSED LOW ALONG THE EASTERN SEABOARD. IF LOW
REMAINS NEAR THE COAST OR INLAND...THEN SIGNIFICANT LATENT HEAT
RELEASE UNDERNEATH THE RIDGE WILL RESULT IN STRENGTHENING THE RIDGE
EVEN MORE. IF THIS SOLUTION VERIFIES...THEN TEMPS COULD EASILY CLIMB
INTO THE UPPER 80S AND PRECIPITATION HOLDING OFF UNTIL TUESDAY AND
WEDNESDAY. AT THIS TIME THOUGH MODELS INDICATE RIDGE FLATTENING OUT
ON TUESDAY AND WEDNESDAY AS COLD FRONT APPROACHES THE NORTHERN GREAT
LAKES. FRONT ALSO BECOMING MORE PARALLEL TO MID LEVEL FLOW AND AS A
RESULT WILL BE SLOW TO MOVE THROUGH THE CENTRAL GREAT LAKES. SO WILL
LINGER PRECIP INTO THURSDAY MORNING. SLOW MOVING CONVECTION WITH
PRECIPITABLE WATER APPROACHING TWO INCHES...WILL ALSO CREATE A HEAVY
RAIN POTENTIAL TUESDAY AND WEDNESDAY.

AVIATION...ISSUED 132 PM EDT THU MAY 25 2006

SURFACE LOW OVER WISCONSIN WILL TRACK ACROSS LOWER MICHIGAN
OVERNIGHT. MVFR STRATUS AHEAD OF IT HAS QUICKLY BEGUN TO MIX OUT
ACROSS SOUTHEAST MICHIGAN...LEAVING VFR CLOUDS GENERALLY 6-10KFT
AHEAD OF THE COLD FRONT. REGIONAL RADARS SHOW STRONGER CONVECTION
DEVELOPING ACROSS WESTERN LOWER ALONG THE WARM FRONT...WHICH LOOKS
TO HAVE QUICKLY JUMPED NORTHWARD WITH BETTER INSOLATION AS CLOUDS
MIX OUT. THIS ACTIVITY LOOKS TO CONTINUE TO DEVELOP SOUTHEASTWARD
ALONG THE FRONT...BUT SHOULD REMAIN NORTH OF MBS GIVEN CONTINUED
NORTHWARD MOVEMENT TO THE BOUNDARY. STILL LOOKING FOR THUNDER
CHANCES ALONG THE COLD FRONT. SIMILAR TIMING IN TAFS WITH TSRA
MENTIONED FOR A TWO HOUR WINDOW BETWEEN 20-24Z. PLENTY OF LOW-LEVEL
MOISTURE UPSTREAM BEHIND THE LOW...WITH MVFR/IFR CLOUDS RETURNING
OVERNIGHT...LOWEST CIGS FARTHER NORTH AT FNT/MBS CLOSER TO THE LOW
TRACK. WILL ALSO STICK WITH THE LONGER/STRONGER MENTION OF RAIN
SHOWERS FARTHER NORTH NEAR THE LOW.
