Area forecast discussion, May 1, 4:17 PM EDT, 56 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
417 PM EDT TUE MAY 1 2007

.SHORT TERM...TONIGHT AND WEDNESDAY...

SEVERE THUNDERSTORM WATCH 205 REMAINS IN EFFECT FOR TWO SOUTHERN
TIERS OF COUNTIES UNTIL 00Z. STRONG TEMPERATURE GRADIENT IS IN
PLACE ACROSS THE REGION WITH SOUTH BEND AT 84F AND PONTIAC AT 50F.
AS THE SURFACE LOW CONTINUES TO TRACK TO THE EAST...THIS FRONT
WILL VERY SLOWLY LIFT NORTH INTO LOWER MICHIGAN BEFORE RETREATING
BACK TO THE SOUTH AS THE SURFACE LOW PASSES TO OUR EAST.
THUNDERSTORMS NORTH OF THE WARM FRONT ARE EXPECTED TO REMAIN
ELEVATED WITH SOME MARGINALLY SEVERE SIZE HAIL POSSIBLE. THE
ATMOSPHERE SOUTH OF THE WARM FRONT IS BECOMING INCREASING UNSTABLE
WITH MSAS ANALYSIS SHOWING AROUND 2500 J/KG OVER NORTHWEST INDIANA
WHERE DEWPOINTS HAVE RISEN INTO THE LOW 60S. STORMS ARE STARTING
TO DEVELOP ALONG THE SURFACE WARM FRONT OVER SOUTHWEST LOWER
MICHIGAN AND WILL FILL IN AND BECOME SURFACE BASED THIS AFTERNOON.
MID LEVEL CAP IN PLACE AROUND 750-600MB HAS KEPT THE ENVIRONMENT
PRETTY SUBDUED TO OUR SOUTHWEST...BUT AS WE CONTINUE TO
DESTABILIZE...STORMS ARE STARTING TO BREAK THROUGH THE CAP. 0-6KM
SHEAR WILL BE ON THE ORDER OF 45-50 KNOTS WITH FLOW BACKED TO THE
EAST NORTH OF THE FRONT. IN ADDITION...A SHORTWAVE IS GOING TO
BRUSH NORTHERN LOWER MICHIGAN WITH STRONG UPPER LEVEL DIVERGENCE
AS THE RIGHT ENTRANCE REGION TO THE UPPER JET IS OVERHEAD. THE
STRONG SHEAR AND INSTABILITY SHOULD BE SUFFICIENT FOR SOME
SUPERCELLS TO DEVELOP...TRACKING TO THE EAST AT 25 MPH THIS
EVENING. STORMS WILL BE CAPABLE OF PRODUCING STRONG WINDS AND HAIL
TO ONE INCH IN DIAMETER WITH THE POTENTIAL FOR EVEN AN ISOLATED
TORNADO.

BY LATE EVENING...SHORTWAVE WILL PASS TO OUR EAST AND THE UPPER
LEVEL RIDGE WILL START TO BUILD AGAIN. SHOWERS WILL SUBSIDE WITH
SUBSIDENCE TAKING OVER BEHIND THE COLD FRONT. MODELS INDICATE THAT
THE SURFACE TROUGH WILL LINGER BACK ACROSS SOUTHEAST MICHIGAN INTO
EARLY WEDNESDAY AND WILL EXPECT LOW CLOUDS TO LINGER THROUGH THE
NIGHT. WILL LIKELY SEE CLOUDS STARTING TO SCATTER OUT BY MORNING
BUT WILL EXPECT TO SEE STRATOCU RE-DEVELOP WITH DAYTIME HEATING.
GUIDANCE TEMPS LOOK GOOD ON WEDNESDAY AND HAVE JUST LOWERED ALONG
THE EDGE OF THE THUMB A COUPLE DEGREES WITH COOL NORTHEASTERLY
FLOW OFF THE LAKE HELPING TO SUPPRESS THEM.

&&

.LONG TERM...A LONG STRETCH OF DRY WEATHER ANTICIPATED WITH LARGE DIURNAL
TEMPERATURE SWINGS AS A MORE AMPLIFIED/BLOCKING PATTERN SETS UP OVER
NORTH AMERICA. NORTHERN STREAM SHORTWAVE TROUGH TO SWING THROUGH THE
CENTRAL GREAT LAKES TONIGHT WITH NORTHWEST CONFLUENT FLOW SETTING UP
WEDNESDAY AND THURSDAY. GENERAL SUBSIDENCE AND GOOD SURFACE RIDGING
ORIGINATING FROM A COOL HIGH OVER ONTARIO WILL PROVIDE MOSTLY CLEAR
SKIES WITH BELOW NORMAL TEMPERATURES THROUGH FRIDAY AS EASTERLY LOW
LEVEL FLOW SETS UP. LATEST GUIDANCE SUPPORTS MINS IN THE MID TO
UPPER 30S ACROSS THE NORTH HALF OF THE CWA WEDNESDAY NIGHT AND
THURSDAY NIGHT...THUS FROST REMAINS A DISTANT POSSIBILITY...BUT WILL
BE DEPENDENT ON WINDS BECOMING LIGHT AND SURFACE DEW POINTS DROPPING
OFF INTO THE UPPER 20S (ALLOWING SURFACE SKIN WET BULBS TO REACH
FREEZING)...WHICH IS NOT A GIVEN WITH THE FLOW COMING OFF OF LAKE
HURON.

UPPER LEVEL RIDGE MOVING OVERHEAD FRIDAY-SUNDAY IS EXPECTED TO
KEEP CLOUDS AND PRECIPITATION ASSOCIATED WITH WEAKENING/SHEARING OUT
UPPER WAVES OVER CENTRAL PLAINS/SOUTHERN CALIFORNIA FROM IMPACTING
SOUTHEAST MICHIGAN...BUT THIS IS WHERE THE FORECAST COULD GO ASTRAY.
12Z GFS ENSEMBLE MEAN SHOWS AIRMASS CONTINUING TO MODIFY THROUGH THE
WEEKEND....AS 850 MB TEMPS WARM TO HIGH SINGLE NUMBERS TO AROUND 10
DEGREES C LATE SUNDAY...SUPPORTIVE OF MAXES IN THE LOWER TO POSSIBLY
MID 70S. EVEN WARMER ON MONDAY WITH MAXES EXPECTED TO PEAK OUT
AROUND 80 DEGREES BASED ON 850 MB TEMPS IN THE LOWER TEENS.

THE UPPER LEVEL RIDGE IS FORECASTED TO FLATTEN AND HEAD OFF TO THE
EAST LATE MONDAY-TUESDAY...WHICH LOOKS TO ALLOW A WEAK FRONTAL
BOUNDARY TO SLIDE INTO NORTHERN LOWER MICHIGAN...SUPPORTIVE OF LOW
CHANCE POPS.

&&

.PREV DISCUSSION...ISSUED 209 PM EDT TUE MAY 1 2007

AVIATION...

SHOWERS AND THUNDERSTORMS WILL CONTINUE TO MOVE THROUGH LOWER
MICHIGAN THIS AFTERNOON AS A LOW PRESSURE SYSTEM TRACKS ACROSS
EXTREME LOWER MICHIGAN. THUNDERSTORMS WILL INCREASE IN STRENGTH AS A
WARM FRONT EXTENDING FROM LAKE MICHIGAN TO NORTHERN OHIO SLOWLY
LIFTS NORTH INTO THE STATE. THE STRONGEST STORMS MAY BE CAPABLE OF
PRODUCING WINDS TO 60 MPH AND SMALL HAIL...WITH SOME POTENTIAL TO
AFFECT THE DETROIT AIRPORTS. TAFS WILL BE UPDATED AS NEEDED TO
INDICATE THE APPROACH OF ANY STRONG STORMS.

THUNDERSTORMS SHOULD MOVE SOUTHEAST INTO OHIO BY MID EVENING AS A
COLD FRONT PUSHES SOUTH ACROSS LOWER MICHIGAN. MODELS INDICATE AN
MVFR DECK OF CLOUDS TO PERSIST THROUGH THE NIGHT...LIFTING INTO A
STRATOCU DECK ON MONDAY.
