USER MESSAGE:  

THIS MESSAGE IS TO INFORM OUR USERS THAT NESDIS IS CONSIDERING DISCONTINUING THE SPENES (TXUS20) PRODUCT AND SIGNIFICANTLY REDUCING THE FREQUENCY OF PRECIPITATION COORDINATION THROUGH 12 PLANET AND NWS CHAT. IF THIS CHANGE OCCURS, THEN NESDIS SATELLITE ANALYSIS BRANCH ANALYSTS WILL BRIEF SATELLITE BASED INFORMATION TO WPC FORECASTERS WHO ARE EXPECTED TO INCORPORATE THIS INFORMATION INTO THEIR MPDs (MESOSCALE PRECIPITATION DISCUSSIONS) (WMO Header: AWUS01 KWNH and AWIPS Header: FFGMPD). FOR MORE INFORMATION, PLEASE SEE THE MESSAGE ON (ALL LOWER CASE EXCEPT FOR THE P IN PRODUCTS) - http://www.ospo.noaa.gov/Products/atmosphere/spe/retire.html TO FILE AN APPEAL, PLEASE CONTACT JOHN.SIMKO@NOAA.GOV OR COMPLETE THIS GOOGLE DOC Appeals Form (USE "SPENES" FOR PRODUCT/ SERVICE RETIREMENT) BY APRIL 27, 2015

.
SATELLITE ANALYSIS AND TRENDS...BIG PICTURE STARTING TO DRIVE THE SMALLER SCALE AS WELL DEFINED SW TO NE ORIENTED MOISTURE PLUME OR CONCENTRATION OF HIGHEST MOISTURE WAS CENTERED FROM THE TX-MEXICO GULF OF MEXICO COAST TO THE TEXAS-LOUISIANA BORDER TO EASTERN ARKANSAS INTO WESTERN TN AND KENTUCKY. DRY/LOW PWAT AIR NOT TOO FAR AWAY AND SHIFTING SLOWLY EAST AND SE ACROSS IOWA AND NORTHERN/WESTERN MO. SO THAT IS THE FIRST CLASH THAT IS CREATING A SHARP INSTABILITY GRADIENT THAT CAN CERTAINLY HELP PRECIPITATION GENERATION AND IN THE COLD AIR SNOW PRODUCTION. WELL DEFINED JET FROM MANITOBA-ALBERTA BORDER SOUTH THROUGH WESTERN WYOMING AND COLORADO AND N/C NEW MEXICO WAS HOOKING UP WITH SUBTROPICAL JET ACROSS S NEW MEXICO...NORTHERN TEXAS AND ACROSS C ARKANSAS INTO WESTERN KY AND SOUTHERN ILLINOIS. MAIN UPPER LEVEL FORCING FEATURE THAT CAME OUT OF COLORADO LATER YESTERDAY AND NOW MOVING ACROSS C KANSAS HAD VARIOUS SUBTLE SHORT WAVE IMPULSES OUT AHEAD ACROSS MISSOURI AND ILLINOIS THAT WAS HELPING TO INTERACT WITH JET TO THE SOUTH AND SLIGHT DIFFLUENCE CENTERED ON MISSOURI AND DEEP MOISTURE E TX TO MISSOURI TO PRODUCE STEADY LIGHT TO MODERATE/OCCLY HVY RAIN SOUTH..IE MOST OF ARKANSAS AND SOUTHERN ILLINOIS AND SE MISSOURI AND LIGHT TO MODERATE/OCCLY HVY SNOW NORTH...IE MOSTLY CENTRAL MISSOURI...C ILLINOIS INTO C INDIANA. WITH CORE OF HEAVIEST SNOW FOLLOWING CLOSE TO THE PATH OF THE 850MB LOW NEAR S CENTRAL/C MISSOURI INTO C ILLINOIS. NESDIS SNOWFALL PRODUCT EARLIER WERE GIVING MAX SNOW-WATER EQUIVALENT (SWE) RATES OF 0.04"/HR CENTERED ON NE AND S CENTRAL MISSOURI EARLIER THIS MORNING AROUND 1030Z AND IR TRENDS WOULD SUGGEST A SLIGHT INCR IN SWE SINCE THAT TIME WHICH COULD TRANSLATE INTO GENERAL 0.5"-1.0"/HR SNOW RATES AND OCCL 1.5"/HR RECENTLY CENTERED E CENTRAL MISSOURI THROUGH CENTRAL ILLINOIS AND ACROSS PORTIONS OF CENTRAL INDIANA WITH INCREASED INTERACTION OF FORCING AND COLD/DRY VS MILD/MOIST CLASH.

AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED BELOW IN APPROXIMATELY 10-15 MINUTES.

SHORT TERM OUTLOOK VALID 1415-1800Z...MEDIUM CONFIDENCE FACTOR IN SHORT TERM OUTLOOK...BAROCLINIC SATELLITE WINTER STORM SIGNATURE LOOKING BETTER PAST FEW HRS AND USUALLY HIGHEST PRECIP FALLS ON SOUTHERN EDGE OF ENHANCED COOLER CLOUD TOPS WITH HEAVIEST SNOW FALLING ALONG PATH OF 850MB LOW AND CLOSE TO THE -5C 850MB TEMP AND THAT SHOULD CONTINUE TO BE E CENTRAL MO THROUGH CENTRAL WORKING INTO INTERIOR NORTHERN ILLINOIS AND INDIANA WITH SNOW RATES UP TO 1"/HR WITH OCCASIONAL HIGHER RATES OF 1.5"-2.0"/HR CENTERED NEAR STL LOUIS...C ILLINOIS (SOUTH OF CHICAGO) INTO C INDIANA CLOSE TO OR JUST NORTH OF INDIANAPOLIS. FOR REFERENCE. IMPRESSED WITH ANOMALOUS NATURE OF HIGH MOISTURE COMING IN FROM E TX/LA AND ARKANSAS AND CLASHING WITH LOW TO MODERATE MOISTURE ILLINOIS AND UPPER MIDWEST, SO THAT THERE COULD BE SNOW RATES OCCLY INCREASING TO MORE THAN 2"/HR AS THIS PERIOD GOES ON IN SNOW AREA OUTLINED JUST ABOVE.
