SATELLITE ANALYSIS AND TRENDS...CENTER OF VIGOROUS MID/UPPER LEVEL
DISTURBANCE SEEN IN WATER VAPOR IMAGERY HAS MOVED NORTHEASTWARD INTO
COLORADO WHILE ADDITIONAL STRONG JET ENERGY CONTINUES TO SPREAD INTO
THE BASE OF THE TROF ACROSS AZ/NM PER GOES HIGH DENSITY WIND PLOT. THE
RESULTANT LARGE SCALE LIFT HAS BEEN EVIDENT IN IR SATELLITE IMAGERY
PARTICULARLY SINCE THE GOES-EAST ECLIPSE PERIOD ENDED(0645Z) WITH CLOUD
TOP COOLING/EXPANSION IN REGION OF INCREASING MODERATE TO HEAVY SNOW
STRETCHING FROM W AND N CENT NEB TO N CENT/NE SD AND WITH A DRAMATIC
INCREASE IN ELEVATED CONVECTION OVER NE KS/SE NEB. SATELLITE TRENDS
AGREE WITH RECENT SWOMCD AND HPC WWD GRAPHICS CONCERNING THE EVOLUTION
OF THE HEAVY SNOW EVENT FOR N CENT NEB/E SD EVENTUALLY SPREADING INTO
S MN. GIVEN THE SIGNIFICANT CLOUD TOP ENHANCEMENT AND LEAF SIGNATURE
IN SATELLITE IMAGERY ALONG WITH THE MODEL FORECAST LOW/MID LEVEL
FRONTOGENESIS PARAMETERS AND BANDING FEATURES EVIDENT IN COMPOSITE
RADAR IMAGERY, CERTAINLY BELIEVE A PERIOD OF GREATER THAN 1"/HR SNOWS
IS LIKELY FOR THE DISCUSSION AREA WITH BURSTS TO 2"/HR POSSIBLE. SOUTH
OF THE RAIN-SNOW LINE HEAVY RAINFALL IS DEFINITELY A CONCERN GIVEN THE
RAPID INTENSIFICATION OF ELEVATED CONVECTIVE ACTIVITY ACROSS NE KS/SE
NEB. BELIEVE THIS BATCH WILL CONTINUE TO INCREASE IN COVERAGE AS IT
MOVES NORTHEASTWARD ACROSS IA AND EVENTUALLY EXTREME S MN/S WI LATER
TODAY. INITIAL SLUG OF MODERATE TO HEAVY RAINFALL CURRENTLY MOVING FROM E
IA ACROSS N IL/S WI MAY SERVE TO EXACERBATE ANY FLOODING CONCERNS IF THE
NEXT AND HEAVIER ROUND ALSO MOVES OVER A PORTION OF THIS AREA. FINALLY,
LINGERING WINTER SOIL CONDITIONS OBVIOUSLY WOULD PLAY A ROLE IN THE
OVERALL EXTENT OF THE RUNOFF THREAT IN SPOTS FARTHER TO THE NORTHEAST.
