AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 335 PM EST TUE DEC 25 2001 MAIN FORECAST PROBLEM IN THE NEAR TERM CONTINUES TO BE PINNING DOWN DETAILS OF LES EACH PERIOD. LAPS MODEL SOUNDINGS SHOWING SOME DRYING AND DIRECTIONAL SHEAR IN THE BOUNDARY LAYER TODAY AS LES HAS HAD DIFFICULT TIME GETTING ORGANIZED. FOR TONIGHT...MODEL SOUNDINGS SHOW IMPROVING CONDITIONS FOR THE ENHANCEMENT OF LES AS MID LEVEL SHORTWAVE TROUGH MOVES THROUGH. MSAS SFC PRESSURE SHOWS A SFC REFLECTION OF THIS TROUGH AND THE VIS SAT LOOP SHOWS WHAT APPEARS TO BE MID-LEVEL VORT MAX MOVING ACROSS NORTHERN ILLINOIS ATTM. IN FACT...THIS FEATURE IS CURRENTLY PRODUCING LIGHT SNOW IN THAT AREA. FORECAST REASONING IS THAT THE TROUGH PASSAGE WILL SEE INVERSION HEIGHTS RISING CONSIDERABLY OVERNIGHT...AS WELL AS LOW LEVEL CONVERGENCE ZONE FORMING AND INTENSIFYING IN SW FLOW AHEAD OF THE TROUGH AXIS THIS EVENING INTO THE OVERNIGHT PERIOD. MESO-ETA SHOWS BEST SFC CONVERGENCE WILL BE FROM ALLEGAN/OTTAWA COUNTIES AND INTO KENT AND MUSKEGON COUNTIES. WILL GO WITH A LES WARNING IN THIS AREA AND BUFFER THE SURROUNDING COUNTIES WITH A LES ADVISORY. LOW TEMPS WILL BE TRICKY AS WELL...AS SW FLOW WILL BRING COLDER AIR TO SOUTHERN INTERIOR ZONES. WILL GO 10 TO 15 IN THAT AREA...15 TO 20 NORTHERN INTERIOR...AND NEAR 20 FOR THE COASTAL ZONES. SOUNDINGS STILL SHOWING DEEP MOISTURE AND INVERSION HEIGHTS AROUND 7-8 KFT RIGHT THROUGH WED EVENING. WILL KEEP THE WARNINGS/ADV GOING THROUGH WED AFTERNOON...ALTHOUGH FLOW APPEARS TO VEER MORE TO THE NW DURING WED AFTERNOON. WILL LET LATER SHIFTS TWEAK THE WARNING/ADV FOR THE DAY ON WED. AXIS OF MID LEVEL THERMAL TROUGH PASSES THROUGH WEDNESDAY AFTERNOON AND INVERSION HEIGHTS LOWER A BIT WEDNESDAY NIGHT...BUT BUT DEEP MOISTURE IS IN PLACE AS WELL AS STRONG LOW LEVEL CAA AND CYCLONIC FLOW...SO WILL KEEP CAT POPS FOR THE WESTERN HALF OF THE CWA...LIKELY EASTERN HALF. WILL CONTINUE THIS TREND RIGHT THURSDAY NIGHT...AS SYNOPTIC SITUATION REMAINS FAVORABLE FOR CONTINUATION OF LES. WILL ALSO CONTINUE WITH TEMPS IN THE INERIOR ZONES SEVERAL DEGREES COLDER THAN COASTAL ZONES. OSTUNO EXTENDED FORECAST UPPER LEVEL LOW CURRENTLY OVER THE THE GREAT LAKES REGION BEGINS TO REDEVELOP TO THE NORTHEAST BY THE WEEKEND. MEDIUM RANGE MODELS HAVE BEEN CONSISTENT WITH THIS FOR SEVERAL RUNS NOW AND SUPPORT THIS TRANSITION. EVEN AS THE UPPER LOW REFORMS LOWER MICHIGAN WILL REMAIN UNDER A MOIST WEST/NORTHWEST FLOW. FOR THE REST OF THE WEEK INTO THE WEEKEND LOW LEVEL WEST/NORTHWEST FLOW WILL CONTINUE WITH A SERIES OF SHORTWAVES ROTATING AROUND UPPER LEVEL LOW. DECENT LOW LEVEL MOISTURE REMAINS TRAPPED BENEATH UPPER LOW AND WITH SHORTWAVES REINFORCING LOW LEVEL COLD AIR ACROSS THE REGION IT LOOKS LIKE LAKE EFFECT SNOW SHOWERS WILL CONTINUE THROUGH THE WEEKEND. THE OPERATIONAL MRF IS FINALLY HINTING AT A LET UP IN THE PRECIPITATION EARLY NEXT WEEK AS A CANADIAN HIGH DROPS INTO THE CENTRAL PLAINS BRINGING DRIER AIR TO THE GREAT LAKES REGION. AS THIS HIGH DROPS S THROUGH THE PLAINS MRF INDICATES WEAK WARM ADVECTION WILL BEGIN IN THE GREAT LAKES REGION DIMINISHING LAKE EFFECT THREAT. HOWEVER... LITTLE CONFIDENCE IN TIMING/DETAILS THIS FAR OUT AND ENSEMBLES DIFFER QUITE A BIT ON TIMING SO WILL CONTINUE CHANCE OF SNOW SHOWERS INTO TUESDAY. WILL LEAVE GOING EXTENDED ESSENTIALLY UNCHANGED WITH SNOW SHOWERS EACH DAY THROUGH THE WEEKEND. GRAHAM LAKE EFFECT SNOW WARNING IN EFFECT TONIGHT AND WEDNESDAY FOR THE FOLLOWING COUNTIES: ALLEGAN...OTTAWA...MUSKEGON...AND KENT.
