Area forecast discussion, May 27, 3:34 AM CDT, 3 hours 27 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE OMAHA/VALLEY NE 334 AM CDT SAT MAY 27 2006 .DISCUSSION... MAIN CONCERNS ARE THE CHANCE FOR PCPN OVER THE NEXT SEVERALS DAYS... ESPECIALLY MONDAY INTO MONDAY NIGHT...AND TEMPERATURES. 08Z SURFACE ANALYSIS SHOWED VARIABLE WINDS OVER THE AREA WITH CONVECTIVE OUTFLOW FROM MCS OVER WRN IA AND NWRN MO. COLD FRONT EXTENDED FROM A LOW OVER CNTRL ND BACK INTO UT. LOW PRESSURE TROUGH STRETCHED FROM SERN WY DOWN INTO ERN CO AND ERN NM. LOW LEVEL MOISTURE CONTINUED TO STREAM NORTH WITH SOUTHERLY WINDS AT THE SURFACE AND 850 MB. TODAY... EXPECT THAT MAIN AREA OF CONVECTION WILL LIFT NEWD AND MOVE OUT OF THE AREA BY LATE MORNING. WILL KEEP A SMALL CHANCE GOING IN WRN IA FOR THE AFTERNOON. HIGHS YESTERDAY WERE AFFECTED SOMEWHAT BY THE CONVECTIVE DEBRIS LEFTOVER FROM NIGHT TIME STORMS. EXPECT THAT TO BE A FACTOR TODAY...BUT NOT AS MUCH AS YESTERDAY. WENT CLOSE TO OR JUST A BIT BELOW MOS NUMBERS FOR HIGHS TODAY...GENERALLY 90 TO 95 MOST AREAS. THINK THERE IS A SMALL CHANCE OF ELEVATED STORMS TONIGHT WITH ACCAS FORMATION IN ASSOCIATION WITH THE LOW LEVEL JET. GFS KEEPS 850 MB MOISTURE IN PLACE AND SHOWS VERY STEEP MID LEVEL LAPSE RATES... 8 TO 9.5 DEGREES C PER KM...OVERNIGHT. FOR NOW...LEFT THE FORECAST DRY ON SUNDAY. TODAY WILL BE WINDY AND HOT....SUNDAY SHOULD BE SIMILAR. PREFER 00Z GFS TIMING ON BRINGING THE COLD FRONT INTO THE AREA MONDAY. NAM/ETA SEEMS A LITTLE TOO FAST. LEFT PRETTY HIGH POPS IN FOR MONDAY NIGHT AS FRONT BECOMES NEARLY PARALLEL TO THE 500 MB FLOW AND A DECENT SHORTWAVE TROUGH MOVES THROUGH THE REGION. MAKE JUST A FEW SMALL CHANGES TO LATER PERIODS. FLOW DEAMPLIFIES BY MID WEEK...BUT THE A RIDGE DEVELOPS OVER THE ROCKIES. THIS PUTS US IN NW FLOW ALOFT. SHORTWAVES MOVING DOWN ACROSS THE AREA WILL BE DIFFICULT TO TIME. LEFT THINGS MAINLY DRY LATE WEEK...BUT THIS WILL NEED ADJUSTMENT AS WE GET CLOSER. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...NONE. IA...NONE. && MILLER
