Latest on Christmas Eve Snow Storm

Some meteorology lingo here, but I'll put it up anyways for you guys.

SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 12/24/10 0753Z SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-763-8678 LATEST DATA USED: GOES-13 0745Z  KUSSELSON . LOCATION...W WISCONSIN...NW ILLINOIS...C AND S MINNESOTA...IOWA... LOCATION...E SOUTH DAKOTA...SE NORTH DAKOTA... . ATTN WFOS...MKX...DVN...ARX...MPX...DMX...FGF...FSD...ABR... ATTN RFCS...NCRFC...MBRFC... . EVENT...VORT TANDEM FOR LIFT...GENTLE MOISTURE ADVECTION...STEADY LIGHT EXT E ND/SD AND C MN...STEADIEST AND HEAVIEST S MN INTO FAR WESTERN WI.. . SATELLITE ANALYSIS AND TRENDS...2 MAIN VORTS SEEN PROVIDING THE FORCING THAT HAS BEEN LATCHING ON TO WEAK TO MODERATE MOISTURE ADVECTION CENTERED TEXAS INTO IA/S MN.  NORTHERN VORT THAT EARLIER HAD CROSSED NORTHERN SD CONSOLIDATED WITH ANOTHER VORT THAT CAME SE ACROSS ND.  RIGHT NOW THAT CONSOLIDATED VORT IS MOVING ACROSS CENTRAL MN AND MARKS THE NORTHERN EDGE OF LIGHT SNOW. SOUTHERN VORT MOVING ACROSS NW IA AND SW MN HAD BEEN LIFTING ENE ACROSS N NEBRASKA/SE SD. THIS VORT HELPING A BIT MORE STEADIER AND HEAVIER SNOWFALL AS MOISTURE TRANSPORT A BIT BETTER AND CLOUD TOPS COOLER AND WITH EMBEDDED OVERSHOOTING CLOUD TOPS THAT CAN HELP PRODUCE BRIEF MODERATE SNOW.  THE LEADING EDGE OF THIS AREA IN MOVING ACROSS FAR SE MN INTO WI.  COOLING CLOUD TOPS FURTHER SOUTH IN SW TO S CENTRAL MO AND ASSOCIATED WITH STRONGER WARM AND MOIST ADVECTION MAY DISRUPT MOIST TRANSPORT INTO IA...SO NOT LOOKING FOR ANY SIGNIFICANT INCREASE IN SNOW EITHER N IA OR JUST TO THE NORTH IN S MN FOR THE NEXT FEW HRS. WILL CONTINUE TO MONITOR...
