ALSO RAISED POPS AND CLOUD COVER ACROSS THESE AREAS. ISOLATED SEVERE STORMS CONTINUE TO DEVELOP AND MOVE ACROSS PORTIONS OF NORTHEAST WY AND SOUTHERN SD. SHORTWAVE ENERGY MOVING EAST-NORTHEAST ACROSS WY AND DEVELOPING LOW LEVEL JET ACROSS WESTERN NEB AND SOUTHWEST SD WILL HELP TO FUEL SHOWERS AND STORMS INTO THE OVERNIGHT HOURS ACROSS A GOOD PART OF THE AREA. && .PREV DISCUSSION... /ISSUED 245 PM MDT SAT JUN 13 2009/ DISCUSSION...CURRENT SURFACE ANALYSIS SHOWS A COLD FRONT ACROSS ND...WITH AN AREA OF HIGH PRESSURE CENTERED SOUTHEAST OF THE REGION. UPPER LEVEL ANALYSIS HAS WEAK RIDGING OVER THE SOUTHERN PLAINS INTO THE NORTHERN ROCKIES...WITH UPPER TROF ALONG THE WEST COAST. CLOUDS ARE GRADUALLY INCREASING ACROSS THE AREA...WITH THE MOST CLOUDINESS ACROSS THE BLACK HILLS AND SOUTHWESTERN SD. REGIONAL RADARS SHOWING SHOWERS AND STORMS DEVELOPING ACROSS EASTERN WY...THE NEB PANHANDLE...AND SOUTHWESTERN SD AT THIS TIME. TEMPS ARE IN THE UPPER 60S AND 70S AT MOST LOCATIONS WITH LIGHT SOUTH TO SOUTHEAST WINDS. DAILY CHANCES FOR SHOWERS AND THUNDERSTORMS CAN BE EXPECTED FOR THE NEXT SEVERAL DAYS AS SOUTHWESTERLY FLOW ALOFT BRINGS NUMEROUS DISTURBANCES ACROSS THE REGION. THREAT FOR SEVERE STORMS OVER THE NEXT FEW DAYS WILL BE HIGHEST SUNDAY AFTERNOON AND EVENING... ESPECIALLY ACROSS THE BLACK HILLS AREA. MOIST SOUTH TO SOUTHEASTERLY FLOW AT THE LOW LEVELS WILL ALSO BRING A THREAT FOR HEAVIER RAINFALL FROM SOME STORMS...ESPECIALLY ON SUNDAY. FOR LATE THIS AFTERNOON AND TONIGHT...SHOWERS AND THUNDERSTORMS WILL CONTINUE TO DEVELOP ACROSS THE REGION. THE BETTER CHANCES WILL BE ACROSS NORTHEAST WY AND SOUTHERN SD...WHERE BETTER MOISTURE AND INCREASING UPPER LEVEL SUPPORT WILL BE IN PLACE. A FEW STRONG STORMS ARE LIKELY INTO THIS EVENING...MAINLY ACROSS THE SOUTHWESTERN CWA...WITH A SEVERE STORM OR TWO NOT OUT OF THE QUESTION. INCREASING LOW LEVEL JET ACROSS NORTH CENTRAL NEB AND SOUTH CENTRAL SD COULD ALSO BE A TRIGGER FOR MORE THUNDERSTORM ACTIVITY ACROSS THOSE AREAS OVERNIGHT. LOWS WILL BE MOSTLY IN THE 50S. SOME LINGERING SHOWERS AND STORMS ARE POSSIBLE EARLY SUNDAY ACROSS SOUTHERN AND WESTERN AREAS...BUT MAIN ACTIVITY SHOULD HOLD OFF UNTIL THE AFTERNOON AS INSTABILITY AND ANOTHER SHORTWAVE APPROACH. HIGHS WILL BE IN THE 70S AGAIN. SURFACE LOW WILL DEVELOP ACROSS NORTHEAST WY DURING THE DAY...ALLOWING FOR BREEZY SOUTH TO SOUTHEAST WINDS TO THE EAST OF THE LOW. BETTER INSTABILITY WILL BE JUST EAST OF THE LOW ACROSS FAR NORTHEAST WY AND WESTERN SD ALONG WITH GOOD VERTICAL AND SPEED SHEAR. MAIN SEVERE THREAT WILL BE ACROSS THESE AREAS... ESPECIALLY IN THE VICINITY OF THE BLACK HILLS...WHERE MORE CONCENTRATED ACTIVITY WILL LIKELY DEVELOP. LARGE HAIL AND STRONG WINDS WILL BE THE MAIN THREATS...BUT THERE IS AT LEAST A SLIGHT THREAT FOR TORNADOES TO THE NORTHEAST OF THE SURFACE LOW...MAINLY ACROSS FAR NORTHEASTERN WY AND NORTHWESTERN SD. LOCALLY HEAVY RAINFALL IS ALSO LIKELY WITH SOME OF THE STORMS AS PRECIPITABLE WATER VALUES WILL BE AROUND 1 INCH ACROSS A GOOD PART OF THE AREA. THE THREAT FOR SEVERE WX SHOULD CONTINUE INTO THE EVENING AS ACTIVITY SHIFTS FURTHER EAST. CHANCES FOR SHOWERS AND STORMS WILL CONTINUE ON MONDAY AS SURFACE LOW MOVES SLOWLY NORTHEASTWARD AND COMPACT SHORTWAVE TROF/UPPER LOW PASS OVER THE NORTHERN PLAINS. BETTER CHANCES WILL PROBABLY BE MORE CONFINED TO NORTHERN PORTIONS OF THE CWA. TEMPS WILL REMAIN SEASONABLY WARM...HIGHS MOSTLY IN THE 70S. SEVERE THREAT ON MONDAY LOOKS A BIT LOWER...BUT A FEW STRONG TO SEVERE STORMS ARE CERTAINLY POSSIBLE FROM THE BLACK HILLS EASTWARD. EXTENDED...THE WEATHER PATTERN THROUGH THE BEGINNING OF THE EXTENDED PERIOD WILL BE DOMINATED BY A LARGE UPPER TROUGH OVER THE WESTERN UNITED STATES WITH SOUTHWEST FLOW ALOFT OVER THE NORTHERN PLAINS. THIS WILL LEAD TO A SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS EACH DAY. THE BEST CHANCE OF SHOWERS AND THUNDERSTORMS WILL COME ON WEDNESDAY NIGHT AND THURSDAY AS THE UPPER TROUGH CROSSES THE NORTHERN PLAINS. TEMPERATURES WILL REMAIN NEAR NORMAL THROUGH THE PERIOD. AVIATION...VFR CONDITIONS ARE EXPECTED ACROSS MUCH OF THE AREA TONIGHT WITH A CHANCE OF SHOWERS AND THUNDERSTORMS. THE BEST CHANCE OF STRONG THUNDERSTORMS WILL BE OVER SOUTHWESTERN AND SOUTH CENTRAL SOUTH DAKOTA. MVFR...WITH AREAS OF IFR...CONDITIONS ARE EXPECTED TO DEVELOP OVER PARTS OF NORTHEASTERN WYOMING AND SOUTHWESTERN SOUTH DAKOTA AROUND 08Z TONIGHT...CONTINUING UNTIL AROUND 15Z SUNDAY MORNING. && .UNR WATCHES/WARNINGS/ADVISORIES...
