AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
718 AM EDT WED APR 10 2013
.AVIATION...
//DISCUSSION...
DEEP PLUME OF MOISTURE IN PLACE THROUGHOUT SE MICHIGAN WILL MAINTAIN
AN EXTENSIVE LOW STRATUS DECK TODAY. A WIDESPREAD IFR CONDITION
WILL EXIST AT ALL TERMINALS INTO THE MIDDAY PERIOD. THERE IS THE
POTENTIAL FOR ONE OR MORE LOCATIONS TO BRIEFLY LIFT ABOVE 1000 FT
DURING THE LATTER HALF OF THE DAY. HOWEVER AN EXPANDING AREA OF
RAIN CONTAINING EMBEDDED THUNDERSTORMS IS FORECAST TO TRACK THROUGH
DURING THIS TIME. LOW CONFIDENCE IN TIMING AND COVERAGE OF
THUNDERSTORMS WILL PRECLUDE A SPECIFIC MENTION.
FOR DTW...EXISTING IFR CEILING LOOKS TO REMAIN IN PLACE THROUGH A
GOOD PART OF THE DAY UNDER MOIST LOW LEVEL NORTHEAST FLOW. LOW
PROBABILITY FOR A THUNDERSTORM TO MOVE ACROSS THE TERMINAL THIS
AFTERNOON.
//DTW THRESHOLD THREATS...
* HIGH CONFIDENCE IN CEILINGS BELOW 5000 FT THROUGH THE TAF PERIOD.
* LOW CONFIDENCE IN THUNDERSTORMS IMPACTING THE AIRPORT THIS
AFTERNOON.
&&
.PREV DISCUSSION...ISSUED 356 AM EDT WED APR 10 2013
SHORT TERM...TODAY AND TONIGHT
REGIONAL ENVIRONMENT OVER NEXT 24 HOURS WILL BE A VIRTUAL CARBON
COPY OF THAT NOTED YESTERDAY...AS SLIGHTLY CONFLUENT WEST-SOUTHWEST
MID LEVEL FLOW DOWNSTREAM OF A SLOWLY EVOLVING HIGHER AMPLITUDE
TROUGH STRUCTURE LEAVES A WELL DEFINED FRONTAL BOUNDARY OSCILLATING
ACROSS THE NORTHERN OHIO VALLEY/SOUTHERN GREAT LAKES. STEADY
925-850 MB MOISTURE TRANSPORT EMBEDDED WITHIN THE DEEPER SOUTHWEST
FLOW RESIDING THROUGHOUT THE WARM SECTOR WILL SUSTAIN A DEEP
MOISTURE PLUME /PW 1-1.5"/ ACROSS SE MICHIGAN DURING THIS TIME.
THIS ADVECTIVE PROCESS WILL CONTINUE TO PROMOTE AT LEAST WEAK
ISENTROPIC UPGLIDE ALONG THE 850-925 MB ELEVATED FRONTAL SLAB PARKED
ACROSS THE REGION. SUSTAINED FRONTAL CONVERGENCE WILL ALSO MAINTAIN
A DEFINED STRIP OF ENHANCED FGEN FORCING IN THAT LAYER...TOPPED BY A
WEAKLY UNSTABLE PROFILE. THE COLLECTION OF SCATTERED RADAR RETURNS
STILL DEVELOPING EARLY THIS MORNING...SOME CONTAINING EMBEDDED
THUNDER...CERTAINLY SUPPORT THE EXPECTATION FOR AN ACTIVE FRONTAL
ZONE TODAY INTO TONIGHT.
THIS BACKGROUND FORCING WILL LIKELY BE SUPPLEMENTED BY THE ARRIVAL
OF ONE OR MORE SHORTWAVES SHEARING OFF THE PRIMARY SOUTHWEST CONUS
LOW AND ANCHORING ALONG THE BAROCLINIC ZONE. FIRST WAVE NOW LIFTING
OUT OF NORTHERN MISSOURI PER RECENT WATER VAPOR. VIRTUALLY ALL
MODEL GUIDANCE GLIDE THIS IMPULSE INTO LOWER MICHIGAN BY MIDDAY.
MODEST HEIGHT FALLS WILL ALSO ALLOW A WEAK SURFACE REFLECTION TO
ALIGN EASTWARD ALONG THE FRONT. A PERIOD OF DEEP ASCENT CONTAINED
WITH THIS WAVE WILL SUPPORT THE EXPANSION OF A MORE ORGANIZED
CLUSTER OF RAIN CARRYING ELEVATED THUNDER ACROSS A PORTION OF THE
AREA. THE HIGH MOISTURE QUALITY INTO THIS DEGREE OF FORCING WOULD
TRANSLATE INTO TO SOME HEALTHY RAINFALL RATES...WITH ANOTHER SWATH
OF 1"+ QPF NOT OUT OF THE QUESTION. WHILE THE WEAK SUBSIDENCE IN
THE WAKE OF THIS WAVE MAY TEND TO DIMINISH THE COVERAGE FOR A TIME
EARLY TONIGHT...THE OVERALL PATTERN LOOKS TO REPEAT ITSELF AGAIN
OVERNIGHT WITH SOME RENEWED NOCTURNAL FORCING ANCHORED BY ANOTHER
MID LEVEL IMPULSE. THIS SETUP BRINGS GROWING CONCERN FOR THE
POTENTIAL OF FLOODING...CONSIDERING THE ADDITIVE IMPACT WITH TIME
THESE WAVES OF PRECIPITATION WILL BEGIN TO HAVE ON AREA WATERWAYS
AND INCREASINGLY SATURATED SOILS. ALTHOUGH STILL IN THE EARLY
STAGES OF THIS PROCESS TODAY...GIVEN THE EXPECTATION FOR ADDITIONAL
HEAVY RAINFALL TO ARRIVE THURSDAY AND THURSDAY NIGHT /SEE LONG TERM
SECTION FOR DETAILS/...WILL GO AHEAD AND PROVIDE A LONGER FUSED
FLOOD WATCH TO HIGHLIGHT THE INCREMENTAL INCREASE IN FLOOD POTENTIAL
OVER THE NEXT 48 HOURS.
THE COOL NORTHEAST FLOW...LIMITED INSOLATION AND INCREASING
PRECIPITATION COVERAGE WILL MUTE THE DIURNAL TEMPERATURE RESPONSE
FOR TODAY. HIGHS MAINLY IN THE 40S. SLIGHT LOW LEVEL COLD AIR
ADVECTION WILL BEGIN TO WORK INTO NORTHERN SECTIONS TONIGHT AS THE
THERMAL GRADIENT TIGHTENS...EASING BOUNDARY LAYER TEMPERATURES TO
WITHIN A DEGREE OR TWO OF FREEZING. A NARROW SUB-FREEZING LAYER OFF
ABOVE THE BOUNDARY LAYER DOES EMERGE OVERNIGHT BENEATH THE WARM
LAYER...BUT ADEQUATE DEPTH AND WARMTH /4-6C/ TO THE WARM LAYER WILL
YIELD ONLY A LIMITED OPPORTUNITY FOR SOME SLEET PELLETS TO MIX IN
ACROSS THE NORTHERN SAGINAW VALLEY/THUMB OVERNIGHT.
LONG TERM...THURSDAY THROUGH TUESDAY
THURSDAY NIGHT WILL MARK THE END OF THE SOAKING PATTERN AS THE SFC
LOW PRESSURE SYSTEM TRACKS ACROSS SOUTHERN MI. THE CUTOFF UPPER LOW
WILL LAG BEHIND A BIT SLOWLY MOVING THROUGH THE GREAT LAKES THROUGH
THE WEEKEND. RIDGE WILL BUILD OVER THE MIDWEST AND INTO SE MI ON
SUNDAY IN BETWEEN THIS PASSING SYSTEM AND THE NEXT SYSTEM FORMING AT
THE NOSE OF A +120 KNOT JET ENTERING THE PACIFIC NW FRIDAY NIGHT.
THIS WILL ALLOW TEMPERATURES TO MODERATE INTO THE BEGINNING OF NEXT
WEEK AS MODELS AGAIN ADVERTISE ANOTHER NEARLY STATIONARY FRONTAL
BOUNDARY POSSIBLY SETTING UP THROUGH LOWER MI.
THURSDAY WILL BE MUCH THE SAME AS THE DAY OR TWO PRIOR. THE WELL
ADVERTISED STATIONARY FRONT WILL REMAIN RIGHT AROUND THE SOUTHERN MI
STATELINE AS THE STILL STRENGTHENING SFC LOW TRACKS RIGHT ALONG IT.
A LEAD VORT MAX IS SHOWN TO WORK THROUGH EARLY THURSDAY WHICH
PERSISTENCE FORECASTING WOULD SUGGEST AN AREA OF HEAVY RAIN AND
THUNDERSTORMS. MID LEVEL DIFFLUENCE WILL WORK INTO THE REGION IN
ADDITION TO THE STRONG 850 TO 925MB FGEN AND ISENTROPIC ACCENT THAT
HAVE BEEN IN PLACE FOR DAYS NOW. THE CENTER OF THE LOW WILL PASS
SOUTH OF DETROIT THURSDAY EVENING/NIGHT WITH A MIDLEVEL SHORTWAVE
ROTATING AROUND THE UPPER LEVEL FEATURE. EXTREMELY MOISTURE RICH
AIRMASS WITH PWATS AROUND 1.5 INCHES WILL KEEP RAIN OVER THE AREA
UNTIL THE COLD FRONT PASSES LATER THAT NIGHT/FRIDAY MORNING.
NORTHERLY FLOW AND CAA ON THE NORTH/WEST SIDE OF THE LOW WILL KEEP
PTYPES IN QUESTION. LATEST MODELS HAVE BEEN TRENDING ON THE WARMER
SIDE FURTHER NORTH SO SOME ADJUSTMENTS WERE MADE TO TAKE MENTION OF
SNOW OUT ON THURSDAY INTO THURSDAY NIGHT. SOME SNOW MAY START TO MIX
IN EARLY FRIDAY MORNING. SLEET HAS BEEN LEFT IN THE FORECAST ACROSS
THE NORTH AS FORECAST SOUNDINGS STILL ADVERTISE A COLD LAYER AT THE
SFC THAT MAY ALLOW PRECIP TO FREEZE UP BEFORE HITTING THE GROUND.
CONFIDENCE IS NOT OVERWHELMING WITH THIS SETUP THOUGH AS WELL MIXED
ENVIRONMENT AND 900MB TEMPS AROUND 10C WILL MAKE IT HARD FOR
DROPLETS TO REFREEZE BEFORE HITTING. WITH MODELS FLUCTUATING THE WAY
THEY HAVE WILL LEAVE IN FOR THE TIME BEING.
IN THE WAKE OF THE COLD FRONT ON FRIDAY MORNING...DRY SLOTTING WILL
SURGE NORTHWARD OVER SE MI. WITH MOISTURE DEPTH SEVERELY SUPPRESSED
TO 800MB AND BELOW...LOOKS LIKE DRIZZLE OR LIGHT SNOW WILL BE THE
PTYPE OF CHOICE. WILL WAIT AND SEE HOW FAST THE UPPER LOW INTRODUCES
THE COLD AIR INTO THE REGION.
BROAD TROUGH SETTING UP OVER THE WEST COAST WITH RIDGING OVER THE
EAST COAST WILL PRODUCE SOUTHWESTERLY FLOW ALONG A REORIENTED
BAROCLINIC ZONE FOR THE START OF THE NEW WEEK. WILL COVER WITH BROAD
BRUSH CHANCE POPS FOR NOW UNTIL INDIVIDUAL FEATURES BEGIN TO DENOTE
WET/DRY PERIODS. WE SHOULD SEE TEMPS RECOVER BACK TO NEAR NORMAL
DURING THIS STRETCH THOUGH.
MARINE...
NORTHEAST WINDS WILL GRADUALLY INCREASE THROUGH THURSDAY AS A LOW
PRESSURE SYSTEM APPROACHES FROM THE PLAINS. SPEEDS WILL BE STRONGEST
OVER LAKE HURON...NORTH OF A FRONTAL BOUNDARY...REMAINING BELOW 20
KNOTS TODAY THEN INCREASING FURTHER WEDNESDAY NIGHT AND THURSDAY.
PERSISTENT AND INCREASING NORTHEAST FLOW WILL CAUSE WAVE HEIGHTS TO
BUILD OVER SAGINAW BAY AND THE LAKE HURON NEARSHORE WATERS OFF
THUMB...RESULTING IN AN EXTENDED PERIOD OF SMALL CRAFT CONDITIONS.
A BRIEF PERIOD OF GALES MAY EMERGE ACROSS CENTRAL LAKE HURON
THURSDAY EVENING...BUT MARGINAL CONDITIONS AND LIMITED DURATION WILL
PRECLUDE A WATCH HEADLINE AT THIS TIME. IMPROVING CONDITIONS WILL
DIMINISHING WINDS AND WAVES ON FRIDAY.
