What forecasters said that day
The local office's own words before this gale warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Detroit, MI wrote its last area forecast discussion before this gale warning went out at Apr 15, 7:03 AM EDT, 3 hours 24 minutes earlier.
Area forecast discussion, Apr 15, 7:03 AM EDT, 3 hours 24 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
703 AM EDT FRI APR 15 2011
.AVIATION...
TRENDS IN SURFACE OBSERVATIONS OVER THE LAST COUPLE OF HOURS HAVE
ALREADY BEEN TOWARD STRENGTHENING EASTERLY WINDS. THE COMBINATION OF
AN INCREASING EASTERLY GRADIENT TODAY AND AFTERNOON MIXING SHOULD
PROVIDE SUSTAINED WINDS AROUND 20 KNOTS...WITH FREQUENT GUSTS AT OR
ABOVE 30 KNOTS. THERE IS FAIRLY HIGH CONFIDENCE ON THE SPEED AND
DIRECTION OF THE FORECAST WINDS. THE GRADIENT WILL ACTUALLY INCREASE
TONIGHT AS DEEPENING LOW PRESSURE APPROACHES THE WESTERN GREAT
LAKES. THE LATEST GUIDANCE SUGGEST ENOUGH OF A MIXED LAYER WILL
REMAIN TO MAINTAIN FAIRLY GUSTY EASTERLY WINDS THROUGH THE NIGHT.
AMPLE DRY AIR WILL AT LEAST KEEP CEILINGS VFR THROUGH THE AFTERNOON.
THE APPROACHING LOW PRESSURE SYSTEM WILL HOWEVER BRING A SURGE OF
MOISTURE INTO SE MI THIS EVENING. THIS WILL ALLOW RAIN TO SPREAD
FROM SOUTH TO NORTH ACROSS THE AREA AFTER 00Z AND WILL LEAD TO
LOWERING CEILINGS AND VISIBILITIES THROUGH THE NIGHT.
&&
.PREV DISCUSSION...ISSUED 339 AM EDT FRI APR 15 2011
SHORT TERM...TODAY AND TONIGHT
A DEEP UPPER LOW IS CLEARLY EVIDENT ON SATELLITE DATA OVER KANSAS.
THE 00Z MODEL SUITE HAVE A REASONABLE HANDLE ON THIS SYSTEM AND ALL
INDICATE IT LIFTING INTO THE LOWER OHIO VALLEY LATE TONIGHT ON THE
NOSE OF A STRONG UPPER JET CORE NOW DIVING ACROSS THE CENTRAL
ROCKIES. THE 06Z SURFACE ANALYSIS SHOWS THE ASSOCIATED SURFACE LOW
OVER THE SOUTHERN/CENTRAL PLAINS...WITH STRONG HIGH PRESSURE OVER
NORTHERN ONTARIO AND QUEBEC. THE EASTERLY GRADIENT WILL INCREASE
THROUGH THE DAY TODAY AS THE SURFACE LOW MOVES ACROSS MISSOURI AND
THE STRONG HIGH PRESSURE SYSTEM REMAINS ANCHORED TO THE NORTHEAST OF
THE STATE. ALTHOUGH WARM AIR ADVECTION IN THE 900-800MB LAYER WILL
LIMIT MIXING DEPTHS SOMEWHAT...MODEL SOUNDINGS ALL INDICATE 30-35
KNOTS DOWN TO 2K FT. THIS WILL RESULT IN A RATHER WINDY DAY WITH
FREQUENT GUSTS EXPECTED TO REACH AT LEAST 35 MPH. THE LIMITED MIXING
DEPTHS SHOULD KEEP MAX TEMPS IN THE LOW 50S...WITH COOLER READINGS
NEAR THE GREAT LAKES /ESPECIALLY THE THUMB/ UNDER THE STRONG
EASTERLY FLOW.
AN AXIS OF DEEP MOISTURE IS STILL FORECAST TO LIFT INTO SE MI LATE
THIS AFTERNOON INTO TONIGHT WELL IN ADVANCE OF THE UPPER LOW. MODEL
SOUNDINGS INDICATE PRECIPITABLE WATER RISING TO 1.1 INCHES OVERNIGHT
AS A 50-70KT LOW LEVEL JET TRANSPORTS GULF MOISTURE INTO THE GREAT
LAKES REGION. SYSTEM RELATIVE ASCENT ALONG THE 300K ISENTROPIC
SURFACE IS EXPECTED TO BE QUITE STRONG...ESPECIALLY OVERNIGHT. THIS
COUPLED WITH DEEP LAYER FRONTOGENESIS AND HIGHLY DIFFLUENT FLOW
ALOFT WILL CONTINUE TO WARRANT CATEGORICAL RAIN CHANCES TONIGHT. THE
RAIN IS EXPECTED TO LIFT FROM SOUTH TO NORTH ACROSS THE FORECAST
AREA BEGINNING THIS EVENING AND CONTINUING THROUGH THE OVERNIGHT.
THE EASTERLY WINDS WILL SUPPLY VERY DRY AIR NEAR THE SURFACE. THIS
SHOULD RESULT IN A LOT OF VIRGA OR SPRINKLES FROM LATE AFTERNOON
INTO THE EARLY EVENING IN ADVANCE OF THE MID LEVEL MOISTURE SURGE.
THE DEGREE OF MOISTURE ADVECTION WILL HOWEVER EVENTUALLY OFFSET THE
DRY AIR NEAR THE SURFACE.
LONG TERM...
STRONG UPPER LEVEL LOW OVER THE CENTRAL CONUS WILL UNRAVEL AND OPEN
UP...MERGING WITH A NORTHERN STREAM TROUGH...DELIVERING ANOTHER COLD
BLAST FOR THE SECOND HALF OF THE WEEKEND. TEMPERATURES ON SATURDAY
ARE TRICKY AS SURFACE LOW TRACKS NORTH THROUGH LAKE MICHIGAN.
HOWEVER...LOOKS LIKE WE WILL BE DEALING WITH AN OCCLUSION AND BACKED
LOW LEVEL FLOW OUT OF THE SOUTHEAST FOR PART OF THE DAY WITH PERIODS
OF RAIN...LIKELY PREVENTING THE POTENTIAL OF 60+ DEGREES THE AIRMASS
WOULD SUPPORT (BASED ON 850 MB TEMPS). WILL HOLD MAXES IN THE
50S...BLEND OF NAM/MAV.
LOW LEVEL COLD ADVECTION WILL ARRIVE IN ERNEST LATE IN THE DAY INTO
SATURDAY NIGHT...WITH 850 MB TEMPS FALLING INTO THE NEGATIVE LOW TO
MID SINGLE NUMBERS ON SUNDAY. LOW LEVEL LAPSE RATES MAY BE STEEP
ENOUGH TO GENERATE A FEW SHOWERS...AND WITH WET BULB ZERO HEIGHTS
DESCENDING TO THE SURFACE BY SUNDAY MORNING...THAT MEANS PRECIP TYPE
COULD BE SNOW...ASSUMING WE GET THE EQL HEIGHTS SUFFICIENTLY HIGH
ENOUGH TO TAP ICE NUCLEI. REGARDLESS...PRECIPITATION CHANCES WILL BE
LOW DUE TO LIMITED AVAILABLE MOISTURE.
THE UPPER LEVEL FLOW WILL TRANSITION TO ENERGETIC PSEUDO
ZONAL FLOW OVER THE CONUS EARLY NEXT WEEK...BEFORE THE FLOW BUCKLES
AND AMPLIFIES BY MID WEEK. DIFFICULT TO TIME SHORTWAVES...BUT
GFS/CANADIAN INDICATING PV FILAMENT RACING EAST SUNDAY NIGHT...WITH
925-850 MB FGEN NEAR THE OHIO BORDER...WORTHY OF CHANCE POPS SOUTH
OF M-59 CORRIDOR. WITH NORTHWEST CONFLUENT FLOW AND SURFACE HIGH
ADVERTISED TO BUILD IN ON MONDAY (PER GFS)...WAS TEMPTED TO PULL THE
POPS FROM THE NORTH HALF OF THE CWA...AS LOW LEVEL FRONTAL BOUNDARY
SHOULD REMAIN SOUTH...OVER THE OHIO VALLEY. HOWEVER...THE 00Z
EUROPEAN SHOWED A STRONGER SHORTWAVE QUICKLY RACING EAST THROUGH THE
STRAIGHTS ON MONDAY...AND THUS THE 850 MB FGEN WAS FARTHER
NORTH...DRAPED ALONG THE I-69 CORRIDOR DURING THE EARLY AFTERNOON
HOURS. MUCH HIGHER CONFIDENCE IN RAIN CHANCES AS WE HEAD INTO
TUESDAY....AS INCREASING SOUTHWEST FLOW AND RAPID CYCLOGENESIS OVER
THE CENTRAL PLAINS WILL ALLOW WARM FRONT TO LIFT NORTH...WITH PLENTY
OF GULF MOISTURE BEING TAPPED. RAIN APPEARS LIKELY FOR BOTH TUESDAY
AND WEDNESDAY (ALONG WITH THUNDERSTORMS AS SHOWALTER INDEX
DROPS WELL BELOW ZERO) BEFORE WE DRY OUT FOR THE END OF THE WORK
WEEK WITH SLIGHTLY BELOW NORMAL TEMPERATURES EXPECTED. AT THIS
TIME...IT LOOKS LIKE SURFACE BASED INSTABILITY WILL STRUGGLE TO RAMP
UP TUESDAY-WEDNESDAY...BUT WILL HAVE TO WATCH THIS CLOSELY AS WIND
FIELDS ARE VERY STRONG (50+ KNOTS 850-700 MB).
MARINE...
THE LATEST SURFACE OBSERVATIONS ALREADY INDICATE WINDS NEARING SMALL
CRAFT ADVISORY CONDITIONS. THE EASTERLY GRADIENT WILL INCREASE
THROUGH THE DAY AS LOW PRESSURE MOVES INTO MISSOURI AND STRONG HIGH
PRESSURE REMAINS ANCHORED NORTHEAST OF LAKE HURON. UNDER THESE
INCREASING EASTERLY WINDS...WAVES WILL CONTINUE TO BUILD DURING THE
COURSE OF THE DAY...WHICH WILL CONTINUE TO LEAD TO TREACHEROUS
CONDITIONS FOR SMALL BOATS. THE WINDS ARE FORECAST TO VEER TO
SOUTHEAST SATURDAY MORNING AS THE SURFACE LOW MOVES INTO LAKE
MICHIGAN. PLAN TO MAINTAIN THE GALE WATCH THAT IS IN EFFECT NORTH OF
ALABASTER FOR TONIGHT AND SATURDAY. MODEL SOUNDINGS SHOW NEUTRAL
CONDITIONS OVER MUCH OF THE LAKE TONIGHT...THEN BECOMING STABLE BY
SATURDAY MORNING AS WARMER LOW LEVEL AIR ADVECTS OVER THE LAKE. THIS
RAISES SOME CONCERNS AS TO WHETHER OR NOT GUSTS TO 35 KNOT GALES
WILL IMPACT THE OPEN WATERS...SO PLAN TO HOLD OFF ON THE ISSUANCE OF
A GALE WARNING AT THIS TIME. THERMAL PROFILES MAY BE MORE SUPPORTIVE
OF GALES NORTH OF THUNDER BAY...WITH CONDITIONS MORE SUPPORTIVE OF
30 KNOT GUSTS TO THE SOUTH. SO AT THIS TIME...THERE IS FAIRLY HIGH
CONFIDENCE THAT A GALE WARNING WILL BE NEEDED NORTH OF PRESQUE
ISLE...WITH MEDIUM TO LOW CONFIDENCE ON ONE BEING NEEDED FARTHER
SOUTH.
THE WINDS WILL WEAKEN A BIT SATURDAY EVENING AS THE SURFACE LOW
PASSES THROUGH THE STRAITS. COLD AIR ADVECTION IN THE WAKE OF THIS
SYSTEM WILL HOWEVER BOOST INSTABILITY OVER THE LAKE AND MAY AGAIN
LEAD TO GALE FORCE WINDS LATE SATURDAY NIGHT INTO SUNDAY NORTH OF
THUNDER BAY.
