NWS Bismarck, ND wrote its last area forecast discussion before the first event at Apr 28, 2:47 PM CST, 52 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BISMARCK ND 347 PM CDT WED APR 28 2010 .SYNOPSIS... A HIGHLY AMPLIFIED FLOW PATTERN WILL ESTABLISH ITSELF ACROSS NORTH AMERICA. THIS IS EXPECTED TO OCCUR AS A BUILDING RIDGE ACROSS THE EASTERN PACIFIC INDUCES THE DOWNSTREAM DIGGING OF A POTENT STORM SYSTEM ACROSS THE PACIFIC NORTHWEST. THIS WILL SET THE STAGE FOR A COOL...WET AND BREEZY PERIOD ACROSS THE NORTHERN PLAINS THROUGH THE WEEKEND. && .SHORT TERM...TONIGHT THROUGH SATURDAY NIGHT THE MAIN FORECAST CHALLENGES DURING THE SHORT TERM PERIOD WILL BE WINDS THIS AFTERNOON...AND THEN WILL TURN TO PRECIPITATION CHANCES AND TEMPERATURES THROUGH THE PERIOD. THE 12 UTC MODEL SUITE IS IN REASONABLE AGREEMENT WITH THE LARGE SCALE FEATURES...SO A MODEL BLEND WAS USED FOR THIS PACKAGE. THE AFOREMENTIONED STORM SYSTEM IS NOW AFFECTING THE NORTHERN PLAINS. A STRONG ASSOCIATED SURFACE LOW ALONG THE FRONT RANGE OF THE NORTHERN ROCKIES HAS LED TO A STRONG PRESSURE GRADIENT ACROSS NORTH DAKOTA THIS AFTERNOON. WINDS HAVE BEEN GUSTING OUT OF THE SOUTHEAST...JUST UNDER THE 50 KNOT WARNING CRITERIA. I AM EXPECTED THE WINDS TO REMAIN UNDER THIS MAGIC NUMBER THROUGH THE AFTERNOON...ALBEIT CLOSE. THEREFORE...NO HIGH WIND WARNING IS ANTICIPATED. HOWEVER...I HAVE UPDATED THE NPW TO WORD IT WITH GUSTS UP TO 55 MPH ACROSS THE JAMES RIVER VALLEY. THE OTHER CONCERN FOR LATE THIS AFTERNOON/EVENING IS THE POSSIBILITY FOR STRONG THUNDERSTORM DEVELOPMENT. LATEST RADAR IMAGERY SHOWS SOME SCATTERED SHOWERS WITH EMBEDDED THUNDERSTORMS ACROSS FAR EASTERN MT AND WESTERN SD. THIS APPEARS TO BE ASSOCIATED WITH AN UPPER LEVEL DISTURBANCE INTERACTING WITH THE FRONTAL ZONE ACROSS WESTERN ND. THIS ACTIVITY SHOULD BECOME MORE ORGANIZED AS A STRONG MID LEVEL JET NOSES IN ACROSS SOUTHERN NORTH DAKOTA. THIS WILL RESULT IN 0-6KM BULK SHEAR IN EXCESS OF 40 KNOTS ACROSS SOUTH CENTRAL NORTH DAKOTA BY EARLY THIS EVENING. THE MAIN LIMITING FACTOR IS LOW LEVEL MOISTURE. MEDIOCRE DEW POINTS IN THE LOW TO MID 40S ARE RESULTING IN UNDER 1000 J/KG OF CAPE. ADDITIONALLY...A RATHER STOUT CAP IS IN PLACE. IN SPITE OF THIS...HEIGHT FALLS AND STRONGER SYNOPTIC SCALE ASCENT ASSOCIATED WITH THE UPPER LEVEL SYSTEM SHOULD ALLOW PARCELS TO REACH THEIR LFC BY EARLY EVENING. THE THREAT FOR SEVERE WEATHER SHOULD DIMINISH OVERNIGHT AND SHOULD BE CONFINED TO SOUTH CENTRAL NORTH DAKOTA. SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE TONIGHT AND ON FRIDAY...MAINLY ACROSS THE JAMES RIVER VALLEY AND POINTS EAST. MOST AREAS WILL LIKELY SEE A DRY PERIOD ON THURSDAY AND THURSDAY NIGHT. DURING THIS TIME...THE UPPER LEVEL LOW WILL PRODUCE ANOTHER AREA OF SURFACE LOW PRESSURE ACROSS SOUTHERN CANADA. THIS SECOND LOW WILL PUSH ANOTHER COLD FRONT ACROSS THE AREA ON FRIDAY. COLDER AIR AND THE TREAT FOR RAIN WILL REENTER THE PICTURE ON FRIDAY. WE COULD EVEN SEE SOME "MAY DAY" SNOW ON SATURDAY MORNING...ESPECIALLY ACROSS THE NORTH. THE CHANCES FOR PRECIPITATION WILL CONTINUE THROUGH THE SHORT TERM PERIOD AS THE UPPER LOW SLOW MOVES EAST. TEMPERATURES WILL BE ON A DOWNWARD TREND INTO THE WEEKEND. HIGH TEMPERATURES WILL MAINLY BE IN THE 50S WITH SOME 40S POSSIBLE OVER THE WEEKEND. .LONG TERM...SUNDAY THROUGH WEDNESDAY NIGHT... LONG TERM MODELS NOT IN GOOD AGREEMENT...AND CONSENSUS WAS TO USE THE EUROPEAN MODEL FOR THE LONG TERM FORECAST. THE LARGE STORM SYSTEM AFFECTING THE CENTRAL PART OF THE COUNTRY IN THE SHORT TERM IS DEPICTED OVER MANITOBA/ONTARIO/MINNESOTA/ERN NORTH DAKOTA SUNDAY MORNING. THE MODEL INDICATES THE SYSTEM LIFTING TO THE NORTHEAST TO HUDSON BAY ON MONDAY. COLD AIR MOVING SOUTH ON THE BACK SIDE OF THIS SYSTEM MAY BE COLD ENOUGH FOR RAIN OR SNOW SHOWERS SUNDAY AND SUNDAY NIGHT. ANOTHER SHORTWAVE FOLLOWING THE MAIN SYSTEM WILL BE ASSOCIATED WITH A SLIGHT CHANCE OF SHOWERS THROUGH MONDAY. ANOTHER LARGE STORM SYSTEM MOVES ONTO THE WESTERN CANADIAN COAST SUNDAY NIGHT/MONDAY AND APPROACHES THE DAKOTAS ON TUESDAY. THIS SCENARIO WOULD SUGGEST SLIGHT CHANCES OF SHOWERS MENTIONED FOR TUESDAY NIGHT IN PARTS OF WESTERN NORTH DAKOTA...AND INTO WEDNESDAY AND WEDNESDAY NIGHT FOR WESTERN AND CENTRAL NORTH DAKOTA. THE TEMPERATURE FORECAST FOR THE LONG TERM IS MORE CHARACTERISTIC OF TRANSITIONAL SEASONS LIKE SPRINGTIME. COOLER WEATHER WHEN THE STORM SYSTEMS ARE OVER THE STATE OR JUST PAST THE STATE WILL BRING LOWS IN THE 30S AND HIGHS IN THE 50S SUNDAY. WARMING AHEAD OF LARGE STORM SYSTEMS WILL MEAN FORECAST HIGHS IN THE 60S TUESDAY AND WEDNESDAY. && .AVIATION... A FRONTAL BOUNDARY ASSOCIATED WITH A LARGE AND VIGOROUS LOW PRESSURE SYSTEM TO OUR WEST WILL SWEEP THROUGH THE STATE TODAY...BRINGING A CHANCE FOR THUNDERSTORMS BEGINNING AT KDIK AND KISN AROUND 21Z...KBIS AND KMOT AROUND 00Z...AND KJMS BY 03Z. SOUTH TO SOUTHEASTERLY 20 TO 30 KNOT WINDS AHEAD OF THE FRONT SHOULD SHIFT TO THE WEST AND DECREASE TO AROUND 15 KNOTS AS THE FRONT PASSES...WITH SOME GUSTS IN THE CENTER OF THE STATE FROM KBIS TO KJMS REACHING TO AROUND 45 KNOTS. EXPECT MOSTLY VFR CONDITIONS THROUGH THURSDAY MORNING...WITH MVFR CONDITIONS AND GUSTY WINDS LIKELY DURING ANY THUNDERSTORM ACTIVITY. && .BIS WATCHES/WARNINGS/ADVISORIES...
