Severe Thunderstorm Warning 8, NWS Detroit, MI

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
414 PM EDT SAT APR 25 2009

.SHORT TERM...THIS AFTERNOON AND TONIGHT

SEVERE THUNDERSTORM WATCH 182 HAS BEEN ISSUED AS A REPLACEMENT...AND
WILL BE IN EFFECT UNTIL 10 PM. THE AWFULLY IMPRESSIVE SURFACE COLD
FRONT...WITH A TEMPERATURE GRADIENT OF ROUGHLY 25 DEGREES...WILL
SLIDE SOUTHWARD THIS EVENING/TONIGHT ARRIVE OVER THE DETROIT METRO
AREA BY TOMORROW MORNING. THIS SOUTHWARD PROGRESSION OF THE LINEAR
FORCING CALLS FOR THE ADDITION OF LENAWEE/MONROE COUNTIES IN THE NEW
WATCH. IT IS A TOUGH CALL IN REGARDS TO THE EXTENT OF THE SEVERE
POTENTIAL MOVING FORWARD AS THE LOW LEVEL ATMOSPHERE ACROSS MUCH OF
THE FORECAST AREA HAS BEEN WORKED OVER. WITH THE DEVELOPED
UNIDIRECTIONAL SOUTHWESTERLY FLOW REGIME...STEEP LAPSE RATES OF THE
ELEVATED MIXED LAYER WILL CONTINUE TO STREAM INTO SOUTHEASTERN
MICHIGAN PROVIDING MUCH NEEDED ENERGY. A MIXED ENVIRONMENT IS IN
PLACE ACROSS SOUTHWESTERN LOWER MICHIGAN/NORTHERN INDIANA...WHICH
WILL SUPPORT THE CONTINUED STORM ORGANIZATION OF LINES AND BOWING
SEGMENTS. DAMAGING WIND GUSTS OF UP TO 70 MPH REMAIN POSSIBLE INTO
THE EVENING. THE CONVECTION CONTINUES TO FIRE ALONG AND AHEAD OF
THE COLD FRONT FROM SAGINAW BAY CLEAR BACK TO CHICAGO...WHICH WILL
TRACK IN DURING THE 22-02Z TIMEFRAME. PERIODS OF SHOWERS AND
THUNDERSTORMS WILL IMPACT THE REGION DURING THE OVERNIGHT. SEVERE
THUNDERSTORMS ARE NOT EXPECTED LATE TONIGHT BUT WILL MONITOR FOR
HEAVY RAINFALL AND THE POTENTIAL FOR FLOODING.

&&

.LONG TERM...TONIGHT THROUGH FRIDAY

THE COLD FRONT HELPING TRIGGER TODAYS CONVECTION IS FORECAST TO
EXTEND ALONG THE SOUTHERN MICHIGAN BORDER BY 12Z SUNDAY. EXPECT
RESIDUAL SHOWERS AND SCATTERED THUNDERSTORMS TO BE ONGOING SUN
MORNING TO THE NORTH OF THE SURFACE BOUNDARY AS STRONG LOW LEVEL
INFLOW CREATES PERSISTENT MOISTURE CONVERGENCE ALONG THE 925-850MB
FRONTAL BOUNDARY DRAPED ACROSS THE NORTHERN AND CENTRAL GREAT LAKES.
THE RATHER ROBUST MID LEVEL WAVE NOW OVER THE GREAT BASIN ON THE
LATEST WATER VAPOR IMAGE IS FORECAST TO LIFT INTO THE NORTHERN
PLAINS ON SUN. AN ASSOCIATED SURFACE LOW WILL TRACK INTO THE UPPER
MISSISSIPPI VALLEY. THIS LOW ALONG WITH STRONG SOUTHERLY LOW LEVEL
FLOW ACROSS THE OHIO VALLEY AND BUILDING MID LEVEL HEIGHTS ACROSS
THE MID ATLANTIC WILL SEND THE FRONT NORTH AS A WARM FRONT DURING
THE COURSE OF THE DAY. THE BETTER 925-850MB MOISTURE
CONVERGENCE/FRONTAL FORCING WILL LIFT NORTH OF THE AREA DURING THE
AFTERNOON. WHILE THE LARGER-SCALE FORCING WILL RESIDE TO THE NORTH
AND NORTHWEST OF THE AREA...CONVERGENCE ALONG THE SURFACE FRONT WILL
WARRANT MAINTAINING A CHANCE OF CONVECTION INTO THE AFTERNOON.
MODELS CONTINUE TO INDICATE A NARROW RIBBON OF MODERATE INSTABILITY
ALONG THE BOUNDARY. GIVEN THE STRONG BAROCLINICITY PRESENT ALONG THE
BOUNDARY...THERE WILL BE A RISK OF LOW TOPPED SUPERCELLS ALONG THE
FRONT AS IT LIFTS NORTH.

MODEL SOUNDINGS INDICATE A SHALLOW YET VERY STRONG POST FRONTAL
INVERSION. WITH THE NORTHEAST SURFACE WINDS OFF LAKE
HURON...TEMPERATURES ACROSS MUCH OF THE FORECAST AREA WILL BE IN THE
40S AND 50S SUN MORNING. DAYTIME HEATING SOUTH OF THE FRONT SHOULD
HOWEVER BOOST TEMPS TO NEAR 80. THIS WARM AIR WILL OVERSPREAD THE
AREA FROM SOUTH TO NORTH DURING THE AFTERNOON AND EVENING WITH THE
PASSAGE OF THE FRONT...CREATING A VERY NOTICEABLE INCREASE IN TEMPS.

SOUTHERN MICHIGAN WILL BE WELL WITHIN THE WARM SECTOR BY MONDAY.
DAYTIME SUNSHINE AND DEEP MIXING WILL CREATE ANOTHER WARM AND BREEZY
DAY. MID LEVEL SHORT WAVE ENERGY WILL TRAVERSE NORTHERN ONTARIO
MON/MON NIGHT...SUPPRESSING THE UPPER LEVEL RIDGE OVER THE MID
ATLANTIC AND DRIVING A COLD FRONT ACROSS LOWER MICHIGAN. THE 12Z
MODEL SUITE CONTINUE TO SUGGEST A TIMING ON THE FRONT ACROSS SE MI
MONDAY NIGHT TO EARLY TUESDAY. AMPLE DEEP LAYER MOISTURE ALONG THE
FRONT COUPLED WITH SOME MID LEVEL FRONTOGENSIS WITHIN THE ENTRANCE
REGION OF THE UPPER JET WILL WARRANT INCREASING POPS TO LIKELY MON
NIGHT. EXPECT SOME PRECIP WILL LINGER INTO TUESDAY BEFORE POST
FRONTAL DRY AIR OVERSPREADS SE MI.

STRONG CANADIAN HIGH PRESSURE BUILDING INTO THE NORTHERN GREAT LAKES
IN THE WAKE OF THE COLD FRONT WILL CONTINUE TO PROVIDE COOL AND DRY
CONDITIONS DURING THE MID WEEK PERIOD. THE MEDIUM RANGE MODEL
SOLUTIONS CONTINUE TO STRUGGLE IN THEIR HANDLING OF ADDITIONAL SHORT
WAVE ENERGY EJECTING OUT OF THE MEAN UPPER TROUGH OVER THE
NORTHWESTERN US LATE IN THE WEEK. LARGE SPREAD AMONG ENSEMBLE
MEMBERS AND POOR RUN TO RUN CONTINUITY LEADS TO A GREATER DEAL OF
UNCERTAINTY TOWARD THE END OF THE LONG TERM. AT THIS TIME...PLAN TO
MAINTAIN THE CHANCE OF PRECIP LATE IN THE WEEK WITH A WARMING TREND
FROM THE COOL MID WEEK TEMPS.

&&

.MARINE...

SMALL CRAFT ADVISORIES WILL BE CONTINUED UNTIL MONDAY NIGHT AS A
DEVELOPED SOUTHWESTERLY FLOW REGIME REMAINS IN PLACE. THE MIXED
LOWER LEVEL ENVIRONMENT WILL ALLOW FOR THE STRONG WINDS TO PUSH OFF
OF LAND AND OUT INTO THE WATERS. SCATTERED SHOWERS/THUNDERSTORMS
WILL BE PREVALENT ACROSS THE AREA THIS WEEKEND AS A STALLING
BOUNDARY REMAIN IN VICINITY OF LOWER MICHIGAN.

&&

.PREV DISCUSSION...ISSUED 155 PM EDT SAT APR 25 2009

AVIATION...

A FAST MOVING BOW ECHO COMPLEX IS ROCKETING THROUGH THE AREA AT
TAF ISSUANCE TIME. THERE HAVE BEEN A FEW REPORTS OF WIND GUSTS IN
EXCESS OF 50 KNOTS. HAVE INCLUDED THE SEVERE WIND GUSTS IN A TEMPO
GROUPING FOR KDET/KPTK/KFNT...BUT LEFT OUT THE SEVERE GUST
MENTION OUT AT KDTW AS THE STRONGEST CONVECTION WILL PASS TO THE
NORTH OF THE SITE. EXPECTATIONS ARE FOR A CONTINUED CHANCE OF
CONVECTION THROUGHOUT THE AFTERNOON AND NIGHT AS A COLD FRONT
STALLS ACROSS THE CWA. IFR CONDITIONS AND NORTHEASTERLY SURFACE
WINDS WILL DEVELOP BEHIND THIS FRONT LATER TONIGHT. PRECIPITATION
WILL CHANGE OVER TO SHOWERS TOWARDS MORNING BEFORE FRONT LIFTS
NORTHWARD.
