NWS Bismarck, ND wrote its last area forecast discussion before the first event at Jul 14, 1:12 PM MST, 2 hours 38 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BISMARCK ND 312 PM CDT SAT JUL 14 2012 .SHORT TERM...TONIGHT THROUGH SUNDAY NIGHT. THE FORECAST CONCERNS IN THE NEAR TERM SURROUND THUNDERSTORMS...ALONG WITH HOT TEMPERATURES ON SUNDAY. A WEAK SURFACE TROUGH IN PARTS OF CENTRAL MONTANA WILL BE THE FOCUS FOR THUNDERSTORMS LATE THIS AFTERNOON INTO THIS EVENING. THE STORMS ARE EXPECTED TO GRADUALLY MOVE INTO PARTS OF WESTERN NORTH DAKOTA THIS EVENING. A FEW OF THE STORMS COULD BE STRONG...ESPECIALLY THIS EVENING WITH MUCAPE VALUES OF 1000-1500 J/KG. THE CHANCE OF STORMS WILL PERSIST OVERNIGHT...AND SPREAD EAST AS THE LOW LEVEL JET AXIS SPREADS INTO WESTERN AND CENTRAL NORTH DAKOTA. THE SURFACE TROUGH MOVES INTO WESTERN NORTH DAKOTA ON SUNDAY. THIS WILL BE THE FOCUS FOR MORE THUNDERSTORMS ON SUNDAY...WITH A FEW SEVERE STORMS POSSIBLE ESPECIALLY IN THE AFTERNOON AND EVENING. 0-1KM MLCAPE VALUES RISE INTO THE 1500-2500 J/KG RANGE ALONG AND AHEAD OF THE BOUNDARY BY MID AFTERNOON...WITH 0-6KM SHEAR VALUES OF 40 TO 50 KTS...SO A FEW SUPERCELLS LOOK POSSIBLE. THE OTHER CONCERN ON SUNDAY WILL BE THE HOT TEMPERATURES. AHEAD OF THE TROUGH...WARMER AIR IS DRAWN INTO THE FORECAST AREA...WITH SOME GUIDANCE VALUES SUGGESTING READINGS COULD APPROACH 100 DEGREES IN SOUTH CENTRAL NORTH DAKOTA. THIS COMBINED WITH DEWPOINTS IN THE LOWER TO MID 60S WOULD PUSH HEAT INDEX VALUES CLOSE TO HEAT ADVISORY CRITERIA DURING THE MID/LATE AFTERNOON. THAT BEING SAID...THERE ARE SOME CONCERNS ABOUT ISSUING A HEADLINE AT THIS POINT...PRIMARILY THE POSSIBILITY OF MID AND HIGH LEVEL CLOUDS HOLDING TEMPERATURES BACK ENOUGH TO KEEP THE AREA FROM REACHING HEAT ADVISORY CRITERIA. WILL HOLD OFF ON THE HEAT ADVISORY HEADLINE FOR NOW DUE TO THE UNCERTAINTY IN CLOUD COVER...BUT WE DID ISSUE A SPECIAL WEATHER STATEMENT HIGHLIGHTING THE HEAT CONCERNS. .LONG TERM...MONDAY THROUGH SATURDAY... THE HIGHLIGHT OF THE EXTENDED FORECAST IS EXPECTED TO BE ABOVE NORMAL TEMPERATURES FOR THE MAJORITY OF THE PERIOD. FOR MONDAY...A COLD FRONT IS FORECAST TO PROPAGATE SOUTH ACROSS THE CWA...AND IS EXPECTED TO ENTER INTO SOUTH DAKOTA BY THE EARLY TO MID AFTERNOON. HIGH TEMPERATURES FOR MONDAY ARE FORECAST TO RANGE FROM THE UPPER 70S NEAR THE INTERNATIONAL BORDER...TO THE LOWER 90S SOUTH OF I-94 WITH FRONTAL MIXING. THE BEST CHANCE FOR CONVECTION WILL BE FOCUSED ALONG AND MORE LIKELY JUST BEHIND THE COLD FRONT ARCHING FROM NORTHWEST NORTH DAKOTA THOUGH THE SOUTH CENTRAL. INSTABILITY AND SHEAR PROFILES DO SUGGEST AN ISOLATED SEVERE STORM CANNOT BE RULED OUT...HOWEVER...WIDESPREAD SEVERE STORMS ARE NOT ANTICIPATED. IN THE WAKE OF THE COLD FRONT...NEAR NORMAL HIGH TEMPERATURES IN THE 80S ARE EXPECTED CWA WIDE TUESDAY AND WEDNESDAY. MUCH OF THE CWA SHOULD BE DRY ON TUESDAY WITH SURFACE HIGH PRESSURE IN PLACE...WITH A CHANCE OF THUNDERSTORMS FOCUSED ACROSS THE FAR WEST IN CLOSER VICINITY TO THE LEE SURFACE TROUGH TUESDAY AND WEDNESDAY. TEMPERATURES REBOUND BACK INTO THE 90S FOR MOST LOCATIONS THURSDAY INTO THE WEEKEND WITH RETURN FLOW AS SURFACE HIGH PRESSURE PROPAGATES INTO THE GREAT LAKES. THE NEXT BEST CHANCE FOR THUNDERSTORMS IS THURSDAY IN A RIDGE RUNNING SCENARIO. HOWEVER...KEPT THE REST OF THE FORECAST DRY THEREAFTER DUE TO UNCERTAINTY. && .AVIATION...SMOKE FROM CANADIAN WILDFIRES WILL CONTINUE TO MAKE FOR HAZY SKIES ACROSS WESTERN AND CENTRAL NORTH DAKOTA...AND KEPT SMOKE IN THE TAF FOR KISN INTO THE EARLY AFTERNOON BEFORE MIXING ALLOWS VISIBILITIES TO IMPROVE. AS WINDS TURN TO THE SOUTHEAST THIS AFTERNOON AND THROUGH THE NIGHT...SMOKE WILL NO LONGER BE AN ISSUE. OTHERWISE...SCATTERED THUNDERSTORMS ARE POSSIBLE LATE THIS EVENING AND THROUGH THE OVERNIGHT ACROSS THE AREA...HOWEVER...UNCERTAINTY IN TIMING AND COVERAGE LENDS ITSELF TO ONLY CODING AS VCTS FOR NOW. LOW LEVEL WIND SHEAR IS ALSO EXPECTED AT ALL TAF SITES LATE TONIGHT INTO SUNDAY MORNING. && .FIRE WEATHER...CLOUDS HAVE LIMITED THE WARM UP ENOUGH IN NORTHERN PORTIONS OF THE RED FLAG WARNING AREA TO KEEP RELATIVE HUMIDITY VALUES HIGHER THAN INITIALLY EXPECTED. SOUTHERN PARTS OF THE RED FLAG WARNING AREA STILL LOOK FAIRLY SOLID WITH TEMPERATURES RISING INTO THE LOWER 90S...AND GUSTY SOUTHEAST WINDS. THOUGHT ABOUT CUTTING BACK THE NORTHERN EXTENT TO THE RED FLAG WARNING SINCE IT HAS BEEN SLOWER TO WARM IN THE AREA...BUT WITH A COUPLE HOURS OF WARMING POTENTIAL LEFT DECIDED TO LEAVE IT IN PLACE. WILL LET THE EVENING SHIFT MONITOR...AND IT THE NORTH REMAINS COOLER THAN EXPECTED...THE RED FLAG MAY BE ABLE TO BE CANCELED EARLY IN THAT AREA. && .BIS WATCHES/WARNINGS/ADVISORIES... RED FLAG WARNING UNTIL 10 PM CDT /9 PM MDT/ THIS EVENING FOR NDZ017-031-032-040-043. && SHORT TERM/FIRE WEATHER...KING LONG TERM/AVIATION...AYD
