AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTH PLATTE NE 155 PM CDT WED AUG 10 2005 ...FORECAST CONCERNS SEVERE WEATHER/HVY RAIN POTENTIAL TONIGHT THRU FRIDAY...MAX TEMPS AND ADDITIONAL RAIN POSSIBILITIES IN THE EXTENDED... .DISCUSSION... AN AUGUST HEAVY RAINFALL PATTERN IS DEVELOPING AS VERY ROBUST SUBTROPICAL MOISTURE IS IN PLACE ACROSS NEARLY ALL OF THE WESTERN U.S....THE WESTERLIES ARE BEGINNING TO MIGRATE SOUTHWARD AND A PNA UA PATTERN IS DIRECTING BLOCKING SFC HIGH PRESSURE INTO THE MIDWEST. TONIGHT...ATM IS APPROACHING SATURATION WITH PWS RUNNING CLOSE TO 1.5 INCHES. LAST NIGHTS PULSE SEVERE EVENT DID LITTLE TO STABILIZED THE MID AND UPPER LEVELS BUT DID COOL THE PBL SO CLOUDS FORMED AND SFC BASED INSTABILITY RELAXED. BOTH THE NAM AND GFS EXPLODE TONIGHT ACROSS THE HEART OF THE FCST AREA SUGGESTING THE ATM HAS REACHED ITS LIMIT. INTENSE RAINFALL RATES SUGGESTED BY BOTH MODELS SUGGEST A FEEDBACK PROBLEM. THE GFS SHOWS DRAMATIC DRYING BY 12Z THUR AM. THIS IS PROBABLY THE LEAST LIKELY SCENARIO. FCST THEN IS FORM SOMETHING A LITTLE MORE CLIMATICALLY LIKELY ATTM. EXPECTED SCATTERED STRONG TO SEVERE TSRA TO DEVELOP OFF THE BLACK HILLS LATE THIS AFTN/EVENING. STORMS ANYWHERE IN THE FCST AREA WILL BE CAPABLE OF LOCALLY VERY HEAVY RAINFALL AS THE 30R75 STORM MOTION IS RUNNING 7 TO 15 KTS. IF THE ACTIVITY CAN COALESCE THEN A MORE WIDESPREAD HEAVY RAIN EVENT COULD DEVELOP. THE LACK OF CLASSIC HVY RAINFALL SYNOPTIC SIGNATURE... APPARENT FEEDBACK AND LOW CONFIDENCE IN BOTH MODELS ABILITY TO FORECAST ELEVATED CONVECTION WILL PRECLUDE FLOOD WATCH ISSUANCE AT THIS TIME. THURSDAY...THE NAM CONTINUES SHOW DEEP MOISTURE AND INSTABILITY ACROSS THE NRN ZONES LATE IN THE AFTN/EVENING. PRESUMABLY AS ADVERTISED ANOTHER DISTURBANCE WILL MOVE ACROSS THE BLACK HILLS AND NWRN NEB AND TRIGGER A MCC OR SOME SORT OF TSRA CLUSTER. SHEAR AND INSTABILITY REMAIN FAVORABLE FOR STRONG TSRA. POTENTIAL FOR SEVERE WEATHER WILL BE CLOSELY MONITORED. FRIDAY...SFC FRONT WILL PRESUMABLY BE IN SOMEWHERE ACROSS SRN NEB. MOISTURE...SHEAR...INSTABILITY...FOCUS AND ANOTHER UA DISTURBANCE APPEAR FAVORABLE FOR AN OUTBREAK OF SEVERE WEATHER...SEE SWODY3. SATURDAY/SUNDAY...THE NAM AND GFS SUGGEST THE SFC FRONT WILL BE BACKED UP INTO THE FRONT RANGE WITH DRIER MORE STABLE AIR IN PLACE ACROSS THE FCST AREA. CONTINUED SLIGHT CHC SHRA/TSRA BUT THIS IS A DOWNGRADE FROM CHC POPS IN THE PREVIOUS FCST. MONDAY THROUGH WEDS...PRESUMABLY...THE PNA HAS DROPPED ENOUGH COOLER AND STABLE AIR SOUTHWARD TO SHUNT ALL THE RAIN INTO KS/OK/N TEX. THE NAM IS NOW SHOWING A MAJOR H5 UA DISTURBANCE LIFTING SLOWLY NEWD THROUGH NEB. THE GFS IS MUCH SLOWER HOLDING THE H5 LOW OVER THE ROCKIES BY WEDS AM. THE CURRENT FCST IS DRY FOR NOW BUT ADJUSTMENTS MAY BE REQUIRED IN LATER FCSTS IF RUN TO RUN CONTINUITY DEVELOPS IN BOTH MODELS. TEMPERATURE FCST...TEMPS CONTINUE TO BE ADJUSTED DOWNWARD SLIGHTLY ABOUT 5 TO 10F BELOW NORMAL DEPENDING ON THE PERCEIVED MAGNITUDE OF THE CANADIAN HIGH PRESSURE DROPPING INTO THE CNTL PLAINS. && LBF WATCHES/WARNINGS/ADVISORIES...NONE. && CDC
