Area forecast discussion, Jun 8, 12:15 PM MDT, 5 hours 41 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BISMARCK ND 115 PM CDT FRI JUN 8 2001 THUNDERSTORM CHANCES ARE MAIN FORECAST PROBLEM...AND IT IS A PROBLEM FOR MANY PERIODS. A SECONDARY PROBLEM IS TEMPERATURE...BEING HELD BACK DURING THE DAY IF THERE ARE STORMS/SHOWERS. IT IS MY VIEW THAT WE ARE FULLY INTO THAT TIME OF YEAR WHEN EVEN THE SHORT TERM FORECAST...OUT 2-3 DAYS...CAN POTENTIALLY UNDERGO SIGNIFICANT CHANGE FROM FORECAST RELEASE TO FORECAST RELEASE DUE TO TIMING OF SYSTEMS. A KEY TO THE SUCCESSFUL FORECAST...IN MY VIEW...IS TO MAINTAIN CONTINUITY WHERE POSSIBLE...AND EXPECT TIMING OF ACTIVE WEATHER TO BE OFF A BIT. YESTERDAY...MODELS WERE IN GOOD AGREEMENT...EVEN ON DETAILS OF QPF. QPF FOR SATURDAY WAS /0.50-0.75/. AT THIS AMOUNT A QUARTER INCH DIFFERENCE IS NOT SIGNIFICANT. TODAY...MODELS ARE AGAIN IN GOOD AGREEMENT OF TIMING AND FEATURES...BUT DIFFER ON RESULTING QPF. AMOUNTS FOR SATURDAY RANGE FROM A FEW HUNDRETHS ON THE ETA TO OVER A QUARTER INCH ON THE AVN. AND AT THIS AMOUNT A QUARTER INCH IS VERY SIGNIFICANT...FROM NOTHING UP TO A QUARTER. SHORT WAVE TROF MOVG THROUGH SOUTHERN SASKATCHEWAN NOW WILL CONTINUE TO TRIGGER SOME STORMS IN THE EAST...SHOULD BE EAST OF THE BIS CWA. LONG WAVE TROF MOVING ONTO THE WEST COAST WILL AMPLIFY THE RIDGE OVER THE NORTHERN PLAINS...WHICH IN TURN DELAYS THE ARRIVAL OF THAT TROF. A WEAK WAVE MAY TRIGGER AN EARLY MORNING STORM SATURDAY...WITH BETTER CHANCES LATER IN THE DAY AND AT NIGHT WITH THE TROF ARRIVAL. THIS IS A DELAY FROM PREVIOUS TIMING. THERE IS SOME CONCERN FOR SEVERE STORMS DUE FAVORABLE SEVERE WEATHER PARAMETERS SETTING UP AHEAD OF TROF...IN THERMAL RIDGE. AS THE UPPER LOW MOVES CLOSER A SERIES OF SHORT WAVE TROFS ADVANCE IN THE SOUTHWEST FLOW...CONTINUED UNSETTLED THROUGH TUESDAY. AS FOR TEMPERATURES...WHERE BOTH NUMERICAL GUIDANCES ARE AVAILABLE THEY ARE IN EXCELLENT AGREEMENT. WILL FOLLOW CLOSELY. .BIS...NONE. JP MARTIN
