AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 639 AM EST SAT JAN 15 2005 .AVIATION... SCATTERED TO BROKEN ALTO STRATUS ACROSS THE FAR SOUTHERN GREAT LAKES SHOULD PERSIST THIS MORNING DUE TO SOME WEAK MID LEVEL FRONTOGENESIS WITHIN THE ENTRANCE REGION OF AN UPPER JET OVER THE STATE. DESPITE THE KGRR 88D VAD PROFILE INDICATING INVERSION HEIGHTS NEAR 5K FEET... LAKE EFFECT HAS BEEN STRUGGLING TO GET ORGANIZED DUE TO VERY DRY AIR ACROSS THE REGION AND A SURFACE RIDGE AXIS POSITIONED JUST SOUTH OF THE STATE. THE BEST LOW LEVEL CONVERGENCE HAS BECOME ESTABLISHED FROM JUST NORTH OF AZO TO LAN AND SHOULD PERSIST THROUGH THE AFTERNOON BEFORE SURFACE RIDGING BUILDS BACK NORTH. SOME DIURNAL CONTRIBUTION SHOULD ALLOW FOR SOME PERIODS OF BKN STRATO CU IN THIS REGION...LIKELY BUILDING INTO FNT. FOR DTW/DET/MBS HOWEVER... WILL KEEP THE STRATO CU SCATTERED. && .DISCUSSION... ISSUED AT 230 AM. COLD BUT QUIET WEATHER THROUGH THE WEEKEND. POLAR VORTEX OVER HUDSON BAY TO SLOWLY DRIFT NORTHEAST.

WILL LEAN TOWARD THE 00Z UKMET...WHICH IS THE MOST AMPLIFIED...AND SEEMS TO BE WHERE THE ETA/GFS ARE HEADED. CURRENTLY... 130 KNOT JET STREAK TRACKING ACROSS SOUTHERN LOWER MICHIGAN THIS MORNING. IR SATELLITE IMAGERY AND SURFACE OBS INDICATING NOTHING MORE THAN A MID DECK OF CLOUDS ALONG WITH A STRAY FLURRY. THESE CLOUDS SHOULD HELP HOLD UP TEMPERATURES ACROSS THE SOUTHERN HALF OF THE CWA....AS BEEN THE CASE OVER SW LOWER MICHIGAN. LITTLE IF ANY CHANGES MADE TO MAXES DURING THE FORECAST PERIOD...WITH SLIGHT TWEAKS TO MINS TO STAY WITHIN 2-3 DEGREES OF GFS MOS. TOO MUCH UNCERTAINTY CONCERNING CLOUD COVER AND WHETHER OR NOT WE DECOUPLE TO GAMBLE MUCH BELOW GUIDANCE. NEXT JET MAX (140+ KNOTS) TO MOVE INTO THE NORTHERN PLAINS SATURDAY NIGHT...DIVING SOUTHEAST INTO THE WESTERN OHIO VALLEY LATE SUNDAY. JET FORCING WILL BE TOO FAR SOUTH TO HAVE A DIRECT IMPACT ON OUR WEATHER. HOWEVER...LONG WAVE TROUGH AXIS DOES MOVE THROUGH THE REGION DURING SUNDAY...WHICH MAY BE ENOUGH FOR FLURRIES/SNOW SHOWERS...AS INVERSION HEIGHTS LOOK TO BE RISING UP TOWARD 5000 FEET. POTENT NORTHERN STREAM SHORTWAVE TO SLIDE THROUGH WESTERN LAKE SUPERIOR SUNDAY NIGHT...AND THROUGH LOWER MICHIGAN MONDAY MORNING...STRENGTHENING THE SURFACE TROUGHING OVER THE LAKES. AS IT STANDS NOW...SURFACE TROUGH/CONVERGENCE LOOKS TO BE STAYING JUST OFFSHORE OVER THE EASTERN THUMB. HOWEVER...IT WILL BE A CLOSE CALL AND WILL NEED TO BE MONITORED. STRONG CLIPPER STILL ON TRACK TO RACE THROUGH THE NORTHERN GREAT LAKES TUESDAY NIGHT/WEDNESDAY. THIS SYSTEM WILL HAVE SOME DECENT PACIFIC MOISTURE TO WORK WITH...AS PW VALUES ARE EXPECTED TO RISE ABOVE A HALF AN INCH OVER LOWER MICHIGAN TUESDAY NIGHT. BOTH 00Z CANADIAN/NOGAPS INDICATING A TRACK WHICH IS A LITTLE TO FAR NORTH FOR SOUTHEAST MICHIGAN TO GET INTO THE BEST WARM ADVECTION ACCUMULATING SNOW. 00Z GFS INDICATING A MORE FAVORABLE TRACK. CERTAINLY THE POTENTIAL OF A 2 TO 4 INCH BURST OF SNOWFALL WITH SPECIFIC HUMIDITIES JUST OVER 3 G/KG. && .DTX WATCHES/WARNINGS/ADVISORIES... .MI...NONE. .LAKE HURON...GALE WARNING...NORTH HALF OF LAKE HURON...THIS MORNING.
