NWS Aberdeen, SD wrote its last area forecast discussion before the first event at Mar 6, 3:01 PM CST, 2 hours 14 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ABERDEEN SD 301 PM CST SAT MAR 6 2010 .SHORT TERM...TONIGHT THROUGH MONDAY NIGHT FORECAST ISSUES IN THE NEAR TERM ARE...WHEN TO END PRECIPITATION CHANCES TONIGHT...AND THE POSSIBILITY OF A DENSE FOG ADVISORY LATER TONIGHT/SUNDAY MORNING. AN AREA OF LOW PRESSURE CONTINUES TO PUSH EASTWARD INTO EASTERN NEBRASKA THIS EVENING. THE HEAVIEST PRECIPITATION IS CLOSELY ASSOCIATED WITH THE UPPER LEVEL LOW...HOWEVER THERE IS STILL A WAA BAND OF PRECIPITATION MOVING THROUGH THE EASTERN CWA. MOST OF THE PRECIPITATION IS FALLING AS EITHER DRIZZLE OR LIGHT RAIN. EXPECT THIS PRECIPITATION WILL GRADUALLY COME TO END AN LATER THIS EVENING. FARTHER WEST...WITH A CLOSE T/TD SPREAD...AREAS OF FOG HAS DEVELOPED...INCLUDING DENSE FOG IN THE SOUTHWEST CWA. PIERRE HAS BEEN REPORTING 1/4SM FOR A WHILE...AND EVEN WEB CAMS SHOW DENSE FOG. WILL NOT BE ISSUING A DENSE FOG ADVISORY AT THIS TIME...BUT EXPECT ONE WILL BE ISSUED LATER THIS EVENING. HAVE MADE ONLY A FEW CHANGES TO THE FORECAST BEYOND TONIGHT AS MODELS DISAGREE WITH THE HANDLING OF THE NEXT WEATHER SYSTEM. HAVE LEANED TOWARDS THE 0Z ECMWF WHICH HAS SLOWED DOWN THE OVERALL PROGRESSION OF THIS SYSTEM. THERMAL PROFILES SUGGEST MOSTLY A RAIN EVENT...HOWEVER A MIX OF FREEZING RAIN COULD BE POSSIBLE AT TIME MONDAY NIGHT. .LONG TERM...TUESDAY THROUGH SATURDAY MAIN FORECAST CHALLENGE IS PRECIPITATION TYPE AND AMOUNT WITH SYSTEM SET TO AFFECT THE REGION DURING THE FIRST HALF OF THE PERIOD. THE EXTENDED MODELS ARE IN DECENT AGREEMENT WITH THE TIMING OF THE SYSTEM...BUT JUST DIFFERENT ENOUGH IN THE TRACK TO MAKE IT CHALLENGING TO DETERMINE EXACTLY WHERE AND WHAT TYPE OF PRECIPITATION WILL OCCUR. THE UPPER PATTERN WILL FEATURE A WAVE OVER THE CENTRAL PLAINS EARLY TUESDAY THAT GETS WRAPPED INTO A TROUGH APPROACHING FROM THE WEST...RESULTING IN UPPER LEVEL ENERGY OVER THE AREA THROUGH AT LEAST THURSDAY NIGHT. THE BROAD TROUGH THEN PUSHES EAST AS AN UPPER RIDGE APPROACHES BY THE WEEKEND. THE SURFACE LOW WILL BE OVER WESTERN KANSAS EARLY TUESDAY...WITH PRECIPITATION ONGOING WHEN THE PERIOD STARTS. THE GFS IS THE MOST PROGRESSIVE OF THE MODELS...TRACKING THE LOW TO THE OHIO VALLEY BY THURSDAY EVENING...WHILE THE ECMWF STILL HAS IT BACK OVER ILLINOIS AT THE SAME TIME. BOTH MODELS KEEP PRECIPITATION OVER THE CWA THROUGH THURSDAY EVENING...BUT VARY IN WHERE HEAVIER AMOUNTS MAY BE POSSIBLE. DUE TO THESE DIFFERENCES...HAVE KEPT VERY GENERAL CHANCE POPS GOING WITH MAINLY RAIN MENTIONED DURING THE DAYTIME PERIODS...AND RAIN/SNOW DURING THE NIGHT. AT THIS TIME...WOULD NOT BE SURPRISED IF THE SNOW IS VERY MINIMAL AS CURRENT TIME SECTIONS SHOW THE LOWER LEVELS REMAINING ABOVE FREEZING THE ENTIRE TIME. HIGH PRESSURE SLIDES OVER THE PLAINS BEHIND THE EXITING SYSTEM ON FRIDAY AND REMAINS DOMINANT THROUGH THE DAY SATURDAY. TEMPERATURES WILL REMAIN MILD THROUGH THE PERIOD AS H85 TEMPS LINGER IN THE -5 TO +2 DEGREE RANGE. 30S TO MID 40S WILL BE COMMON FOR DAYTIME HIGHS...WITH MID 20S TO LOWER 30S FOR NIGHTTIME LOWS. && .AVIATION... SKIES WILL REMAIN OVERCAST TONIGHT. CIG LEVELS WILL GENERALLY BE MVFR/VFR DURING THE EVENING...WITH THE EXCEPTION OF THE SOUTHWESTERN CWA WHERE IFR CIGS AND LIFR VSBYS IN DENSE FOG ARE OCCURRING. EXPECT TO SEE THE CIGS LOWER ACROSS THE ENTIRE CWA THROUGH THE NIGHT...WITH IFR CIGS EVERYWHERE BY MORNING. MAY BEGIN TO SEE THE VSBYS IMPROVE SOME AROUND KPIR LATER TONIGHT...BUT ALL TAF SITES SHOULD BEGIN TO SEE MVFR VSBYS IN FOG AFTER 00Z SUNDAY. && .HYDROLOGY... A FLOOD WATCH CONTINUES FOR JONES/LYMAN COUNTIES DUE TO ICE JAM POTENTIAL ALONG THE WHITE RIVER. THAW IN SOUTHEAST SOUTH DAKOTA...WITH COOLER TEMPERATURES AND MORE SNOWPACK DOWNSTREAM ARE THE PRIMARY REASONS. && .ABR WATCHES/WARNINGS/ADVISORIES... SD...FLOOD WATCH THROUGH SUNDAY MORNING FOR JONES-LYMAN. MN...NONE. && SHORT TERM...SD LONG TERM...PARKIN AVIATION...PARKIN WEATHER.GOV/ABERDEEN
