Area forecast discussion, Jul 5, 2:08 AM MST, 9 hours 57 minutes before
AREA FORECAST DISCUSSION FOR WESTERN SD AND NORTHEASTERN WY NATIONAL WEATHER SERVICE RAPID CITY SD 308 AM MDT TUE JUL 5 2011 .DISCUSSION...LATEST WATER VAPOR IMAGERY SHOWS FIRST WAVE OF ENERGY MAKING ITS WAY THROUGH THE EAST PORTIONS OF THE FORECAST AREA WITH ANOTHER WAY PUSHING INTO THE SOUTHWEST CORNER OF THE AREA. 08Z SURFACE ANALYSIS HAS WEAK HIGH PRESSURE OVER THE AREA WITH AMPLE MOISTURE AT LOWER LEVELS AS DEW POINTS CONTINUE TO HOLD IN THE LOWER 60S ACROSS THE SOUTH DAKOTA PLAINS. SOME DRIER AIR IS IS LOCATED OVER WESTERN NORTH DAKOTA...AS DEW POINTS ARE IN THE MIDDLE 40S TO LOWER 50S. FOR TODAY...EXPECT LINGERING CONVECTION THIS MORNING WITH SECOND WAVE OF ENERGY PUSHING ACROSS THE FORECAST AREA THIS MORNING. THIS SECOND WAVE WILL COMBINE WITH THE CONVECTION OUTFLOW FROM LAST NIGHT TO PRODUCE ISOLATED/SCATTERED STORMS TODAY. AFTERNOON HEATING AND DESTABILIZATION COMBINED WITH WEAK FORCING WILL BE ENOUGH TO PRODUCE ADDITIONAL STORMS THIS AFTERNOON...WITH THE MAIN FOCUS BEING OVER NORTHEASTERN WYOMING AND THE BLACK HILLS. DON/T EXPECT A LOT OF STORMS...HOWEVER THE ONES THAT DO DEVELOP WILL MOVE SLOWING AND ARE CAPABLE OF PRODUCING HEAVY RAIN. CONTEMPLATED A FFA FOR THIS AFTERNOON AND TONIGHT...BUT MY OVERALL CONFIDENCE WAS NOT THAT HIGH SO DECIDED AGAINST IT. WILL LET NEXT SHIFT REEVALUATE AS NEEDED. FOR TONIGHT...CHANCE/SLIGHT CHANCE OF STORMS CONTINUE AS A WEAK WAVE SLIDES ACROSS THE AREA. HOWEVER OUT OF THE ENTIRE SHORT TERM PERIOD...IT APPEARS THIS WILL BE ONE OF THE QUIETER NIGHTS AS MOST OF THE FOCUS WILL BE SOUTH OF THE AREA. ON WEDNESDAY AND WEDNESDAY NIGHT...THERE WILL BE A BETTER CHANCE FOR STORMS AS ANOTHER WAVE MOVES THROUGH THE AREA AND MONSOONAL MOISTURE PUSHES ACROSS THE FORECAST AREA. ALSO A WEAK LOW LEVEL TRIES TO DIVE INTO THE NORTHERN PORTIONS OF THE FORECAST AREA. THESE FACTORS COMBINED WITH RELATIVELY SLOW STORM MOVEMENT AND PRECIPITABLE WATER VALUES ABOUT 150 PERCENT OF NORMAL WILL SET THE STAGE FOR STORMS WITH LOCALLY HEAVY RAINFALL. FOR THURSDAY AND THURSDAY NIGHT THE PATTERN REMAINS THE SAME WITH SIMILAR CONDITIONS TO WEDNESDAY. THUS MORE STORMS WITH LOCALLY HEAVY RAINFALL WILL AGAIN BE POSSIBLE. EXTENDED...PATTERN REMAINS UNSETTLED AS MULTIPLE SHORT WAVES SLIDE THROUGH LOW AMPLITUDE RIDGE OVER THE REGION...THEREFORE HAVE CONTINUED CHANCES FOR PRECIP THROUGH THE PERIOD. TEMPERATURES WILL REMAIN NEAR TO SLIGHTLY ABOVE AVERAGE. && .AVIATION...SCT SHRA AND TSRA ARE EXPECTED OVER THE AREA TODAY INTO TONIGHT...PARTICULARLY OVER NERN WY AND FAR WRN SD WHERE SOME STORMS MAY BECOME SEVERE. LCL IFR VIS WILL BE POSSIBLE IN HEAVIER PRECIP. OTHERWISE...VFR CONDITIONS ARE EXPECTED. && .UNR WATCHES/WARNINGS/ADVISORIES... SD...NONE. WY...NONE. &&
