AREA FORECAST DISCUSSION FOR WESTERN SD AND NORTHEASTERN WY NATIONAL WEATHER SERVICE RAPID CITY SD 233 PM MST THU MAR 4 2010 .DISCUSSION...CURRENT SURFACE MAP SHOWS LIGHT WINDS ACROSS THE AREA. LOW CLOUDS/FOG OVER SNOW COVER IN EASTERN PORTIONS OF FORECAST AREA HOLDING TEMPERATURES DOWN AROUND 30...WHILE 50S COMMON ACROSS NORTHEAST WYOMING AND SOUTHWEST SOUTH DAKOTA. MAIN CONCERN IN THE SHORT TERM IS STRONG/COMPACT UPPER LOW THAT WILL CROSS THE AREA FRIDAY/FRIDAY NIGHT ALONG WITH PRECIP AMOUNTS/TYPE. FOR TONIGHT...WEAK EASTERLY BOUNDARY LAYER FLOW COMBINED WITH ABUNDANT MOISTURE WILL ALLOW FOG TO REDEVELOP OVERNIGHT ACROSS WESTERN SOUTH DAKOTA. LOWEST VISIBILITIES ACROSS NORTHWEST SOUTH DAKOTA. WILL HOLD OFF ON ANY ADVISORY FOR NOW THERE IS SOME QUESTION AS TO HOW WIDESPREAD FOG WILL BECOME. FRIDAY/FRIDAY NIGHT...UPPER LOW CURRENTLY MOVING THROUGH THE GREAT BASIN WILL LIFT ACROSS THE ROCKIES TONIGHT AND INTO WESTERN NEBRASKA FRIDAY EVENING. STRONG 700-500 Q-VECT CONVERGENCE LIFTS ACROSS WESTERN SOUTH DAKOTA FRIDAY AFTERNOON/EVENING. WITH LAPSE RATES OF 7-8C/KM AND AVAILABLE MOISTURE...PRECIPITATION WILL SPREAD ACROSS THE AREA. INITIALLY TEMPERATURES ARE WARM ENOUGH FOR LIQUID PRECIP. HOWEVER...AS COLD CORE OF UPPER LOW GET CLOSER AND THEN PASSES OVER THE AREA...RAIN WILL CHANGE TO SNOW. DECENT AGREEMENT AMONG THE MODELS WITH HEAVIEST PRECIPITATION FALLING ACROSS NORTHEAST WYOMING INTO WESTERN SOUTH DAKOTA...SEVERAL INCHES OF SNOW POSSIBLE. FREEZING RAIN POTENTIAL APPEARS TO BE LIMITED TO NORTHWEST SOUTH DAKOTA WHERE MID LEVEL TEMPERATURES REMAIN WARMER. UPPER LOW PULLS EAST ON SATURDAY...WITH SOME PRECIPITATION LINGER INTO THE AFTERNOON HOURS. EXTENDED...SHORTWAVE RIDGE WILL PASS OVER AND EAST OF THE AREA ON SUNDAY. LOOKS LIKE WARMEST TEMPS WILL BE OVER SOUTHERN AND WESTERN PORTIONS OF THE CWA...AS TEMPS GET INTO THE 40S TO NEAR 50. SOUTHERLY FLOW ALOFT WILL DEVELOP LATE SUNDAY AND SUNDAY NIGHT AHEAD OF NEXT STORM SYSTEM...WHICH WILL BE MOVING ACROSS THE SOUTHWESTERN CONUS. THIS SHOULD BRING SHORTWAVE ENERGY INTO THE AREA SUNDAY NIGHT AND MONDAY...WITH A GOOD CHANCE OF RAIN AND SNOW...ESPECIALLY ACROSS SOUTHERN AND EASTERN PORTIONS OF THE CWA. FAIRLY SIGNIFICANT DIFFERENCES CONTINUE BETWEEN THE VARIOUS MEDIUM RANGE MODELS WITH REGARD TO TRACK AND TIMING OF STORM SYSTEM... THOUGH THEY SEEM TO BE COMING INTO A BETTER CONSENSUS ON A MORE SOUTHERN ROUTE FOR THE MAIN LOW AS RIDGE TO THE EAST IS PROGGED TO BE WEAKER. GFS IS FURTHER NORTH THAN ECMWF AND CANADIAN...THEREFORE MOST AGGRESSIVE WITH PCPN POTENTIAL. OVERALL TREND HAS BEEN FURTHER SOUTH SO WILL NOT RAISE POPS UP MUCH ACROSS THE AREA...JUST A LITTLE ACROSS SOUTHERN AND EASTERN PORTIONS OF THE CWA LATE SUNDAY NIGHT THROUGH MONDAY NIGHT. LOOKS LIKE BULK OF PCPN WILL FALL AS SNOW AT NIGHT...WITH RAIN/SNOW DURING THE DAY...ESPECIALLY ACROSS SOUTHERN AND WESTERN AREAS. ASSUMING THE SYSTEM PROGRESSES EAST QUICKLY ENOUGH...MOST OF THE PCPN SHOULD MOVE OUT OF THE AREA TUESDAY NIGHT. && .AVIATION...WIDESPREAD IFR/LIFR CONDITIONS WILL CONTINUE ACROSS MOST OF THE NORTHWESTERN AND WEST CENTRAL SOUTH DAKOTA PLAINS THIS MORNING WITH DENSE FOG AND LOW STRATUS. IMPROVEMENTS TO VSBY/CIGS ARE EXPECTED BY EARLY AFTERNOON ACROSS WEST CENTRAL SD. HOWEVER...IFR/LIFR CONDITIONS ARE LIKELY TO LINGER ACROSS MUCH OF NORTHWESTERN SD THROUGH THE DAY AND INTO TONIGHT...WITH SOME FOG RETURNING TO SOUTHWESTERN SD THIS EVENING. && .HYDROLOGY...MINOR FLOODING OCCURRING ALONG WHITE RIVER AND TRIBUTARIES FROM NEBRASKA STATE LINE TO NEAR THE INTERIOR AREA. NOT MUCH ICE IN THE RIVER...HOWEVER VISIBLE SATELLITE INDICATES THAT THERE REMAINS SOME DECENT SNOW COVER ACROSS SOUTHERN SHANNON COUNTY. FLOOD ADVISORY CONTINUES FOR SHANNON/JACKSON COUNTY. DOWNSTREAM OF THAT AREA...WHITE RIVER HAS SOLID ICE COVER. WITH THE INCREASE IN FLOW AND ADDITIONAL SNOW MELT...THREAT FOR SERIOUS ICE JAM FLOODING IS INCREASING. PRECIPITATION THAT FALLS TOMORROW/TOMORROW NIGHT WILL ONLY ADD TO THE PROBLEM. WILL KEEP FLOOD WATCH IN EFFECT THROUGH SUNDAY. ONCE ICE JAM FLOODING BEGINS...FLOODING CONCERNS COULD PERSIST FOR A WEEK OR MORE. && .UNR WATCHES/WARNINGS/ADVISORIES... SD...FLOOD WATCH THROUGH SUNDAY MORNING FOR MELLETTE-TRIPP. WY...NONE. &&
