KSWhat forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Bismarck, ND wrote its last area forecast discussion before this severe thunderstorm warning went out at May 24, 1:46 PM MDT, 3 hours 57 minutes earlier.
Area forecast discussion, May 24, 1:46 PM MDT, 3 hours 57 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BISMARCK ND 246 PM CDT SAT MAY 24 2008 .SHORT TERM...SATURDAY THROUGH TUESDAY NIGHT... MODELS ARE IN GOOD AGREEMENT CONCERNING SATURDAY AFTERNOON MIDDLE LEVEL SHORTWAVE/JET STREAK ENERGY PASSING OVER CENTRAL NORTH DAKOTA WHILE REVOLVING AROUND A CORE UPPER LEVEL LOW IN EASTERN MONTANA. IT APPEARS THAT THE 12 UTC GFS IS ALONE IN HOW IT HANDLES ASSOCIATED PRECIPITATION...HOWEVER...SINCE IT EXPANDS THE ONGOING CONVECTION OVER SOUTH CENTRAL NORTH DAKOTA AND PROGRESSES IT NORTHEASTWARD. MEANWHILE...BOTH THE 12 UTC NAM AND 00 UTC ECMWF INSIST THAT THE CONVECTION WILL FIRE OVER CENTRAL SOUTH DAKOTA AND MOVE NORTHEASTWARD INTO EASTERN NORTH DAKOTA. AT THIS TIME HAVE CHOSEN TO GO WITH A FORECAST MORE LIKE THE 12 UTC GFS...SINCE THE 17 UTC SURFACE OBSERVATIONS INDICATE THAT THE SURFACE COLD FRONT IS ALONG THE SOUTH DAKOTA/WYOMING BORDER AND EXTENDS SOUTH FROM THERE. THE CONVECTIVE INITIATION POINT SHOULD BE THE JUXTAPOSITION OF MIDDLE LEVEL SHORTWAVE ENERGY AND THE SURFACE TROUGH EXTENDING OUT OF SOUTHEAST MONTANA AND INTO THE NEBRASKA PANHANDLE...WHICH CORRESPONDS WELL TO THE AXIS OF INSTABILITY AND GREATEST MIDDLE LEVEL HEIGHT FALLS. THE STORM MOTION VECTOR IS NEARLY DUE NORTH AT 60 KNOTS. THEREAFTER...EXPECT PRECIPITATION TO PUSH NORTHEASTWARD TONIGHT...WITH LINGERING SHOWERS A POSSIBILITY ON SUNDAY DUE TO STEEPENING LAPSE RATES AS DAYTIME HEATING COMBINES WITH COLD MIDDLE LEVEL TEMPERATURES ASSOCIATED WITH THE MIDDLE LEVEL LOW. TEMPERATURES SHOULD BE SLIGHTLY BELOW AVERAGE TO AVERAGE IN THE SHORT RANGE...AND WINDS WILL PRESENT PROBLEMS UNTIL THE NEXT SURFACE RIDGE PASSES OVER NORTH DAKOTA ON MONDAY EVENING/TUESDAY. FINALLY...THE NCEP/STORM PREDICTION CENTER IN NORMAN OKLAHOMA HAS ISSUED A TORNADO WATCH FOR MUCH OF CENTRAL AND SOUTH DAKOTA UNTIL 10 PM CDT. WHILE NORTH DAKOTA IS NOT INCLUDED IN THE WATCH AREA...IT IS REASONABLE TO EXPECT SOME OF THE SEVERE CONVECTION TO CROSS THE BORDER THIS EVENING AND CAUSE HAIL OR HIGH WINDS OVER SOUTH CENTRAL AND SOUTHEASTERN NORTH DAKOTA. .LONG TERM...WEDNESDAY THROUGH SATURDAY NIGHT... MODELS IN FAIR AGREEMENT ON THE GENERAL TREND WEDNESDAY THROUGH FRIDAY. THE MODELS HAVE SPLIT FLOW ALOFT ON WEDNESDAY...WITH THE FORECAST AREA UNDER THE INFLUENCE OF A BROAD TROUGH...BUT BY SATURDAY THE MODELS INDICATE THAT WE WILL BECOME UNDER THE INFLUENCE OF THE NORTHERN FLOW AS AN UPPER LEVEL SHORT WAVE/TROUGH MOVES INTO CENTRAL CANADA. OVERALL THIS TREND INDICATES BETTER CHANCE OF PRECIP AFTER WEDNESDAY...BUT WITH TEMPERATURES NEAR NORMAL. THIS IS IN LINE WITH THE PREVIOUS FORECAST SO ONLY MINOR CHANGES MADE. && .AVIATION... THE SURFACE LOW WAS IN IN THE SOUTHEAST CORNER OF MONTANA THIS AFTERNOON AND WILL CONTINUE TO MOVE SLOWLY NORTH THROUGH SUNDAY MORNING. THE SYSTEM IS DEEP AND BROAD WITH SHOWERS TO ITS NORTHWEST AND SHOWERS AND THUNDERSTORMS TO ITS EAST. THIS WILL BRING A BROAD RANGE OF WEATHER CONDITIONS TO EASTERN MONTANA AND NORTH DAKOTA... WITH HEAVY RAIN AND HAIL POSSIBLE WITH THE THUNDERSTORMS IN SOUTH CENTRAL AND EASTERN NORTH DAKOTA...AND LIGHT TO MODERATE RAIN AND FOG IN EASTERN MONTANA AND WESTERN NORTH DAKOTA. STRONG SURFACE WINDS CAN ALSO BE EXPECTED. && .FIRE WEATHER... FIRE WEATHER CONCERNS SHOULD BE MINIMAL OVER THE NEXT FEW DAYS. MANY AREAS OF WESTERN AND CENTRAL NORTH DAKOTA HAVE ALREADY RECEIVED AROUND A HALF INCH OF PRECIPITATION SATURDAY...WITH MORE SHOWERS AND/OR THUNDERSTORMS EXPECTED SATURDAY EVENING INTO SUNDAY MORNING. GIVEN GREENNESS VALUES LARGELY OVER 30 PERCENT AND VERY RECENT RAINFALL...RANGELAND FIRE INDICES SHOULD REMAIN WELL BELOW THE VERY HIGH TO EXTREME LEVELS THAT HAVE BECOME COMMON IN NORTH DAKOTA THIS SPRING. ALL THAT SAID...IT IS STILL IMPORTANT TO NOTE THAT THUNDERSTORMS ARE FORECAST OVER THE NEXT DAY OR TWO...SO THERE IS A CHANCE FOR SOME LIGHTENING-INITIATED FIRES OVER THE WESTERN AND CENTRAL PARTS OF THE STATE. && .BIS WATCHES/WARNINGS/ADVISORIES... WIND ADVISORY UNTIL 7 PM CDT /6 PM MDT/ THIS EVENING FOR NDZ002>005-010>013-019>023-025-034>037-042-045>048-050-051. && SCHECK/TSW
