Area forecast discussion, Jun 12, 10:50 AM CDT, 4 hours 15 minutes before
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE JACKSON MS 1050 AM CDT SUN JUN 12 2011 .UPDATE...CURRENT SATELLITE IMAGERY DEPICTS DECAYING MCS CURRENTLY MOVING EAST/SOUTHEAST ACROSS EASTERN KANSAS AND INTO WESTERN MISSOURI. IN ADDITION...OVER OUR REGION...THE SUBTROPICAL RIDGE IS BUILDING IN FROM THE WEST BUT WE WILL BE JUST ON THE EASTERN PERIPHERY OF IT SUCH THAT THE REGION WILL REMAIN UNDER NORTHWEST FLOW ALOFT....WHICH WILL ALLOW SUCH MCS ACTIVITY OR ANY OUTFLOW TO DRIFT DOWN INTO OUR DIRECTION. THIS MAY BE THE CASE LATER TODAY AND COULD BE SOME FOCUS FOR ADDITIONAL SHOWER AND THUNDERSTORM ACTIVITY. THE BEST LOCATION TO SEE THESE STORMS WOULD BE EAST OF THE MISSISSIPPI RIVER...WHERE THE LEAST INFLUENCE FROM THE BUILDING RIDGE WILL EXIST AND A RESIDUAL BOUNDARY FROM OVERNIGHT CONVECTION MAY RESIDE. AS FOR MICROBURST POTENTIAL...ANALYSIS INDICATES THAT THERE IS A RISK FOR TODAY GIVEN PRETTY STEEP LAPSE RATES(30-32 C VERTICAL TOTALS OFF AREA SOUNDINGS). THE SBCAPE AND DCAPE ARE DECENT....SO ANY STORM THAT BECOMES STRONG TO SEVERE WILL BE CAPABLE OF SMALL HAIL AND GUSTY WINDS YET AGAIN TODAY. NOT EXPECTING TOO MUCH IN THE WAY OF SVR STORMS....BUT THIS WILL BE MONITORED THROUGH THE DAY. STORMS THAT DEVELOP WILL LIKELY INITIATE ON THE EASTERN PERIPHERY OF THE BUILDING RIDGE AND DRIFT TO THE SOUTH AND THIS IS INDICATED PRETTY WELL ON LOCAL AND NATIONAL HI-RES WRF RUNS. AS FOR TEMPERATURES...WE ARE RUNNING A GOOD 4-6 DEGREES COOLER THIS MORNING IN THE EAST THAN YESTERDAY. WITH SOME ADDITIONAL RAINFALL YESTERDAY AND THE COOLER START TO THE DAY...FEEL IT MIGHT BE A STRUGGLE TO REACH THE UPPER 90S ACROSS THE EAST. HAVE BUMPED DOWN THE HIGHS HERE TO THE MID 90S AND THIS MAY NOT BE ACHIEVED IF CONVECTION BEGINS EARLIER IN THE AFTERNOON RATHER THAN LATER. ELSEWHERE...TEMPERATURES ARE RUNNING WARMER AND THE MID TO UPPER 90S MAY BE MORE ACHIEVABLE WITH THE BUILDING RIDGE AND LESS CHANCE FOR CONVECTION. UPDATED PRODUCTS BEING SHIPPED OUT. /28/ && .AVIATION...THERE WERE LESS PATCHY AREAS OF FOG THIS MORNING AND WHAT FOG DEVELOPED HAS LONG SINCE DISSIPATED. VFR CONDITIONS WERE BEING OBSERVED AND WILL PREVAIL THROUGH THIS EVENING OUTSIDE OF TSTM ACTIVITY. THE TSTMS SHOULD BE ISOLATED OVER THE WESTERN HALF OF THE AREA AND BE MORE SCATTERED OVER THE EAST. MOST OF THE ACTIVITY WILL DISSIPATE THIS EVENING BUT ADDITIONAL ACTIVITY MAY AGAIN MOVE INTO THE AREA FROM THE NORTH OVERNIGHT. A BRIEF PERIOD OF MVFR VISIBILITIES FROM 10Z TO 13Z WILL BE POSSIBLE MONDAY MORNING. /22/ && .PRELIMINARY POINT TEMPS/POPS...
