DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0144 AM CST FRI NOV 08 2013
VALID 101200Z - 111200Z
...NO TSTM AREAS FORECAST...
...SYNOPSIS...
WHILE MODELS INDICATE THAT MID/UPPER FLOW OVER THE CENTRAL AND
EASTERN PACIFIC MAY UNDERGO CONSIDERABLE AMPLIFICATION DURING THIS
FORECAST PERIOD...LITTLE CHANGE TO THE DOWNSTREAM PATTERN ACROSS
MUCH OF THE U.S. IS EXPECTED FROM SATURDAY INTO SUNDAY. A
TRANSITION FROM BROADLY ANTICYCLONIC TO CYCLONIC FLOW DOES APPEAR
LIKELY ACROSS PARTS OF THE NORTHERN PLAINS INTO THE UPPER
MISSISSIPPI VALLEY LATE SUNDAY INTO SUNDAY NIGHT...ON THE SOUTHERN
FRINGE OF A DIGGING/INTENSIFYING SHORT WAVE IMPULSE EMERGING FROM
THE ARCTIC LATITUDES. AT THE SAME TIME...A LOW-AMPLITUDE IMPULSE
EMERGING FROM THE SUBTROPICAL EASTERN PACIFIC IS FORECAST TO MIGRATE
EASTWARD INTO AND THROUGH THE SOUTHERN PLATEAU/ROCKIES REGION.
HOWEVER...LITTLE APPRECIABLE DESTABILIZATION IS CURRENTLY EXPECTED
IN ASSOCIATION WITH EITHER FEATURE...AND THE RISK FOR THUNDERSTORM
ACTIVITY IS EXPECTED TO REMAIN NEGLIGIBLE.
