AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
1221 PM EDT WED JUN 18 2014

.AVIATION...

//DISCUSSION...

VARIABLE, BUT PREDOMINANTLY VFR, CONDITIONS AND LIGHT SOUTH WINDS
WILL BE THE RULE IN THE VERY NEAR TERM AS A CONVECTIVE COMPLEX
GATHERS OVER THE WEST SIDE OF THE STATE. THUNDERSTORMS PRESENTLY
OVER EASTERN LAKE MICHIGAN ARE EXPECTED TO HOLD TOGETHER AND REACH
SOUTHEAST MICHIGAN AROUND 19Z, SUPPORTING A PREVAILING MENTION OF
TSRA AT ALL TAF SITES DURING THE MID/LATE AFTERNOON. WILL ATTEMPT TO
DEFINE THE FORECAST PEAK INTENSITY PERIOD WITH A BRIEF TEMPO GROUP
FEATURING FURTHER REDUCED VSBY/GUSTS. THE STORMS MAY CARRY A SEVERE
POTENTIAL BY THIS TIME...MAINLY FOR THE DETROIT AREA TAF SITES. HIGH
PRESSURE WILL BRING TRANQUIL CONDITIONS BY TONIGHT, BUT MOIST
NORTHEAST FLOW OFF OF LAKE HURON COMBINED WITH REMNANT MOISTURE FROM
TODAY'S RAINFALL WILL PRESENT POTENTIAL FOR LIGHT FOG/MVFR CLOUD
COVER TOWARD MORNING.

FOR DTW...THUNDERSTORMS WILL APPROACH FROM THE WEST DURING THE
18Z-19Z PERIOD AND ARE FORECAST TO DIRECTLY IMPACT THE AIRFIELD
DURING THE 19Z-20Z

//DTW THRESHOLD THREATS...

* HIGH CONFIDENCE THAT THUNDERSTORMS WILL IMPACT KDTW AIRSPACE AFTER
19Z.

* MEDIUM CONFIDENCE IN CEILINGS AOB 5KFT OUTSIDE OF T-STORMS

&&

.PREV DISCUSSION...ISSUED 1149 AM EDT WED JUN 18 2014

UPDATE...

CONVECTIVE COMPLEX OVER LAKE MICHIGAN REMAINS IN TACT AND STRONGLY
TIED TO MCV FORCING AS IT FEEDS OFF OF AN ELEVATED UNSTABLE LAYER
EVIDENT IN REGIONAL SOUNDINGS THIS MORNING. UPPER AIR DATA VOID
BETWEEN THE QUAD CITIES AND CINCINNATI LEAVES THE QUAD CITIES AS THE
BEST, BUT LESS-THAN-IDEAL, APPROXIMATION FOR THE THERMODYNAMIC
ENVIRONMENT UPON WHICH THIS ACTIVITY HAS BEEN FEEDING. REINFORCING
THE ELEVATED NATURE OF INSTABILITY IS, ATTM, COLD AIR OVER LAKE
MICHIGAN, WHICH WILL CEASE TO BE AN ISSUE ONCE THIS ACTIVITY MOVES
ONSHORE IN WESTERN LOWER MICHIGAN. COMBINED WITH SOME DEGREE OF
DIURNAL RECOVERY OF THE BOUNDARY LAYER, EXPECTATIONS ARE FOR THIS
ACTIVITY TO HOLD TOGETHER WITH REASONABLY GOOD ODDS TO BECOME
INCREASINGLY ROOTED IN THE BOUNDARY LAYER AS IT ROLLS EAST INTO
SOUTHEAST MICHIGAN DURING THE MID-AFTERNOON HOURS. IN ADDITION, WEAK
RIDGING EVIDENT JUST IN ADVANCE OF THE COMPLEX MAY BE HELPFUL IN
TERMS OF ALLOWING THE MODERATELY UNSTABLE AIRMASS OVER NORTHERN
INDIANA/OHIO TO BUBBLE NORTHWARD AND PRESENT A MORE ORGANIZED SEVERE
THREAT ALONG/SOUTH OF THE I-94 CORRIDOR. AT THIS TIME, THE PRIMARY
THREAT REMAINS WIND WITH SECONDARY THREAT OF HAIL. AN ISOLATED
TORNADO IS NOT OUT OF THE QUESTION. GRIDS/ZONES HAVE BEEN UPDATED TO
INCLUDE LIKELY POPS DURING THE 18Z-00Z PERIOD.

PREV DISCUSSION...ISSUED 259 AM EDT WED JUN 18 2014

SHORT TERM...TODAY AND TONIGHT

A STRONG MID LEVEL SUBSIDENCE BUBBLE/CAPPING INVERSION OVERSPREAD SE
MI MON AFTERNOON IN THE WAKE OF THE CONVECTIVE COMPLEX WHICH ROLLED
ACROSS THE NRN GREAT LAKES. THIS SUBSIDENCE NOT ONLY INHIBITED
CONVECTION LAST EVENING BUT HAS HELD STEADFAST INTO THE OVERNIGHT.
UPSTREAM SATELLITE/RADAR COMPOSITE HOWEVER SHOW A SERIES OF
CONVECTIVE CLUSTERS EXTENDING FROM SW LOWER MI TO THE NORTHERN
PLAINS. THESE STORMS HAVE DEVELOPED NORTH OF A SFC WARM FRONT WITHIN
A BROAD REGION OF LOW LEVEL WARM AIR ADVECTION/ISENTROPIC ASCENT.
THE SOUTHERLY INFLOW HAS BEEN TRANSPORTING A HIGHLY UNSTABLE AIR
MASS NORTH OF THE SFC WARM FRONT. 00Z RAOBS FROM ACROSS THE REGION
SHOW A PLUME OF STEEP MID LEVEL LAPSE RATES FROM THE UPPER MIDWEST
ACROSS THE GREAT LAKES.

THE UPSTREAM WATER VAPOR SHOWS SEVERAL CONVECTIVELY INDUCED MID
LEVEL IMPULSES...THE STRONGEST OF WHICH IS NOW SLIDING ACROSS THE
MN/IA BORDER. THESE WAVES WILL TRACK ACROSS LOWER MI THIS MORNING
INTO THE AFTERNOON AND WILL AID IN ERODING THE CAP OVER SE MI THIS
MORNING. THIS WILL PROVIDE AN OPPORTUNITY FOR AT LEAST SCATTERED
CONVECTION LASTING THROUGH THE AFTERNOON. MEANWHILE...THE SFC WARM
FRONT /EXTENDING FROM KBEH TO KTOL AS OF 07Z/ WILL ATTEMPT TO LIFT
NORTHWARD TODAY UNDER DAYTIME HEATING AND S-SW FLOW IN THE WARM
SECTOR. CONVECTIVE OUTFLOW MAY HOWEVER SLOW ITS NORTHWARD PROGRESS
AND LEADS TO A GOOD DEAL OF UNCERTAINTY AS TO HOW FAR NORTH THIS
BOUNDARY WILL MAKE IT TODAY. THE STEEP MID LEVEL LAPSE RATES ARE
SUPPORTING GOOD CAPE DENSITY WITH 0-3KM MU CAPE OF 1500 TO 3000
J/KG. GIVEN 0-6KM BULK SHEAR VALUES WILL BE UP AROUND 40 KNOTS AND
CONSIDERING THE DEGREE OF ELEVATED INSTABILITY...THERE IS AGAIN A
CHANCE OF DAMAGING WINDS AND LARGE HAIL WITH ANY THUNDERSTORM.
MODERATE TO HIGH INSTABILITY IS EXPECTED TO DEVELOP WITHIN THE MOIST
AIR MASS ALONG/SOUTH OF THE SFC WARM FRONT. ANY STORM THAT BECOMES
ROOTED IN THE BOUNDARY LAYER ALONG THIS FRONT WILL HAVE THE
POTENTIAL TO DEVELOP INTO SUPERCELLS. THE CHANCES FOR SEVERE WEATHER
WILL BE HIGHER SOUTH OF A SAGINAW TO SANDUSKY LINE /CLOSER TO THE
BETTER INSTABILITY/.

THE APPROACH OF THE UPPER LOW INTO THE NRN PLAINS TONIGHT WILL BUILD
THE MID LEVEL RIDGE ACROSS THE MS VALLEY AND WRN GREAT LAKES. THIS
WILL HELP NUDGE STRONG SFC HIGH PRESSURE OVER NRN ONTARIO TOWARD
LAKE HURON...WHICH IN TURN WILL STRENGTHEN THE LOW LEVEL NE FLOW
OVER SE MI. THIS WILL FORCE THE SFC FRONT BACK TO THE SOUTH...
BRINGING MUCH MORE STABLE AIR /MODIFIED BY THE MARINE LAYER/ INTO SE
MI. THIS ALONG WITH BUILDING MID LEVEL HEIGHTS WILL SIGNIFICANTLY
LOWER THE CHANCES FOR ADDITIONAL CONVECTION DURING THE COURSE OF THE
NIGHT.

LONG TERM...THURSDAY THROUGH TUESDAY

STRONG SURFACE HIGH PRESSURE WILL SETTLE INTO HUDSON BAY AND
NORTHERN ONTARIO TOMORROW...WHILE UPPER SHORTWAVE RIDGING AMPLIFIES
OVERHEAD. TREND IN THE MODELS HAS BEEN MORE AGGRESSIVE WITH
EXPANDING THE SURFACE RIDGE INTO THE CENTRAL GREAT LAKES...RESULTING
IN A FORECAST THAT PUSHES THE FRONTAL BOUNDARY CURRENTLY DRAPED OVER
SOUTHERN MICHIGAN FURTHER SOUTH INTO FAR SOUTHWEST MICHIGAN AND
OHIO. POPS WERE THEREFORE DECREASED FOR THURSDAY AND THURSDAY
EVENING...LEAVING ONLY SMALL CHANCES SOUTH AND WEST OF A LINE FROM
OWOSSO TO DETROIT. SEVERE WEATHER IS NOT EXPECTED IF ANY STORMS DO
FORM...WITH A VERY LIGHT WIND FIELD IN PLACE AND ONLY WEAK ELEVATED
INSTABILITY EXPECTED TO BE OVERHEAD. ANY THUNDERSTORM OR SHOWER THAT
DOES DEVELOP WILL BE CAPABLE OF PRODUCING VERY HEAVY RAINFALL...AS
PW VALUES OVER THE SOUTHERN PORTION OF THE FORECAST AREA REMAIN
BETWEEN 1.5 AND 1.75 INCHES AND STORM MOTION IS EXPECTED TO BE ONLY
A MEAGER 5-10 KNOTS. TEMPERATURES WILL COOL A FEW MORE DEGREES ON
THE NORTH SIDE OF THE FRONT THURSDAY...ESPECIALLY WITH EASTERLY FLOW
OFF THE GREAT LAKES. TEMPERATURES SHOULD RANGE FROM NEAR 80 WELL
INLAND TO NEAR 70 CLOSER TO THE LAKESHORES.

UPPER/SURFACE LOW PRESSURE MOVING INTO MANITOBA BY FRIDAY WILL THEN
ALLOW THE FRONT TO LIFT BACK NORTHWARD THROUGH THE AREA LATE
THURSDAY NIGHT THROUGH FRIDAY NIGHT. THIS SHOULD PROVIDE A GOOD
CHANCE FOR SHOWERS AND THUNDERSTORMS ACROSS THE AREA AGAIN...WITH
MODELS SHOWING GOOD ISENTROPIC ASCENT ALONG THE 300K SURFACE AND
GOOD THETA-E ADVECTION BACK INTO LOWER MICHIGAN.

MEDIUM RANGE MODELS THEN STRUGGLE WITH THE EVOLUTION AND EASTWARD
MOVEMENT OF THE UPPER LOW NOW SEEN ON WATER VAPOR NEAR THE NORTHERN
ROCKIES. 00Z GFS IS NOW A FAST OUTLIER WITH BRINGING THE LOW AND A
COLD FRONT ACROSS MICHIGAN LATE SUNDAY INTO MONDAY. LATEST EURO HAS
TRENDED SLOWER...BRINGING THE LOW AND FRONT THROUGH STARTING ON
TUESDAY. EURO SOLUTION...WHILE IT IS A FULL DAY SLOWER THAN ITS
PREVIOUS RUN HAS SOME SUPPORT FROM THE UKMET AT 144 HOURS (00Z TUE)
AND THE GEM. A SLOWER SOLUTION COULD OPEN THE DOOR TO A DRIER
FORECAST FOR THE WEEKEND AND A MORE ACTIVE PERIOD OF WEATHER MONDAY
INTO TUESDAY. WILL HAVE TO WATCH TRENDS TO SEE IF LARGER ADJUSTMENTS
TO THE FORECAST ARE NEEDED.

MARINE...

LOW PRESSURE LIFTING UP THROUGH THE MIDWEST WILL STRENGTHEN A
FRONTAL BOUNDARY LYING OVER SOUTHERN LOWER MICHIGAN. THIS WILL BRING
ROUNDS OF SHOWERS AND THUNDERSTORMS TO THE CENTRAL GREAT LAKES
TODAY...WITH THE EXCEPTION OF NORTHERN LAKE HURON WHICH WILL REMAIN
UNDER THE INFLUENCE OF HIGH PRESSURE CENTERED OVER ST JAMES BAY. THE
HIGH WILL EXPAND SOUTHWARD TONIGHT AND THURSDAY...PUSHING THE
FRONTAL BOUNDARY SOUTH AND WEST OF THE AREA...AND ALLOWING FOR A
QUIETER DAY. THE FRONT WILL EVENTUALLY LIFT BACK NORTHWARD LATE
THURSDAY NIGHT INTO FRIDAY AS ANOTHER LOW PRESSURE SYSTEM MOVES INTO
MANITOBA...SPREADING SHOWERS AND THUNDERSTORMS BACK INTO THE AREA.
WIND SPEEDS LOOK TO REMAIN UNDER 20 KNOTS THOUGH THE MID-WEEK
PERIOD...WITH A DIRECTION PRIMARILY FROM THE NORTHEAST. THE
STRONGEST WINDS AND LARGEST WAVES WILL BE OVER SAGINAW BAY...WHERE A
FUNNELING EFFECT WILL HAVE AN IMPACT ON WINDS AND WAVES.
