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...TO SAY THE LEAST...COMPLICATED PATTERN WITH TRANSITION TO SNOW IN EXT SE ILLINOIS AND WESTERN PART OF S INDIANA RAIN AREAS THIS PERIOD...ALL SNOW REST OF ILLINOIS...C AND N INDIANA INTO S MICHIGAN AND SNOW PUSHING EAST ACROSS NW OHIO. MAIN SATELLITE FEATURES WERE NOW WELL DEVELOPED MOISTURE PLUME SHIFTING SLOWLY EAST WITH ITS AXIS FROM THE WESTERN GULF OF MEXICO TO WESTERN TENNESSEE AND ADVECTING MOISTURE IN AN EFFICIENT MANNER INTO INDIANA AND WESTERN OHIO. LIKE SAID EARLIER...SOME OF THE BEST PRECIPITATION PRODUCERS HAVE LOW LEVEL WINDS PARALLEL THE HIGHEST MOISTURE THAT ALLOWS THE RELEASE OF MODERATE TO HVY PRECIPITATION TO BE MORE EASILY BE REPLACED BY ADDITIONAL HIGH MOISTURE BEING ADVECTED IN. THIS THE CASE RIGHT NOW AND WHOLE AREA WILL KEEP SHIFTING EAST AND ENE NEXT 3HRS. LATEST NESDIS SNOWFALL RATE PRODUCT THAT USES MICROWAVE DATA FROM POLAR ORBITING SATELLITES TO PRODUCE SNOW-WATER EQUIVALENT RATES IN THE CLOUDS WAS SHOWING AT 16Z MAX RATES OF 0.06"-0.09"/HR WITH COLDEST CLOUD TOPS BAND OF COMMA TAIL PUSHING ACROSS INDIANA. THIS CAN CERTAINLY BE TRANSLATING INTO SNOWFALL RATES OF 1-1.5"/HR WITH ISOLATED 2.0"/HR RATES AND IF T-STORMS ARE OCCURRING MAYBE EVEN 2.5"/HR RATES JUST NORTH OF INDIANAPOLIS FOR EXAMPLE. ONE SHORT WAVE LIFTING NE THRU NE ILLINOIS WAS BOTH HELPING TO GRAB WESTERN EDGE OF DEEP MOISTURE FOR MODERATE/OCCL SNOW IN THE CHICAGO AREA AND EXTENSION OF THAT SHORT WAVE WAS HELPING TO PRODUCE THE HVY SNOWS IN THE NORTHERN INDIANA AREA AS IT SHIFTS EAST. FURTHER SOUTH MINOR BUT IMPORTANT WEAK SHORT WAVES GOING ACROSS NE MO/W CENTRAL ILLINOIS AND C ILLINOIS WERE ALSO ACTING ON DEEP MOISTURE THAT WAS CONVEYOR BELTING BACK WEST TO HELP PRODUCE THE LIGHT TO MODERATE SNOW IN C ILLINOIS. MAIN UPPER LEVEL DISTURBANCE HANGING FURTHER BACK WAS CROSSING NW MO AND OUT AHEAD PROVIDING THE LIFT AND LATCHING ON TO THE CONVEYOR BELT MOISTURE TO PRODUCE THE LINGERING LIGHT TO OCCL MODERATE SNOW IN THE E CENTRAL MO/STL AREA THAT WILL BE SHIFTING OUT OF THERE DURING THE NEXT 3-4HRS. ALSO OF INTEREST WAS SUBTROPICAL-POLAR JET COMBO FROM THE SOUTHERN PLAINS TO SOUTHERN ILLINOIS/INDIANA INTO OHIO THAT WAS ALSO HELPING TO PROVIDE DESTABILIZATION TO ACT ON DEEP MOISTURE ADVECTION AND MIXING IT UP IN THE COLDER AIR FURTHER NORTH AND NW FOR THE HEAVY SNOW CENTERED N INDIANA/NE ILLINOIS INTO EXT S MI AND NW OHIO.

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 1830-2130Z...MEDIUM CONFIDENCE FACTOR IN SHORT TERM OUTLOOK...ALL ENTITIES DESCRIBES ABOVE SHIFTING EAST AND NE. EXPECT HIGHEST SNOW AMOUNTS THIS PERIOD TO BE ACROSS NORTHERN HALF OF INDIANA/FAR SOUTHERN MICHIGAN INTO N OHIO WITH SNOW RATES COULD MAX OUT AT 1.5"-2.0"/HIGHLY ISOLATED 2.5"/HR WITH ANY T-STORMS (SEE GRAPHIC SHORTLY). BACK UPPER LEVEL DISTURBANCE MISSOURI SHIFTING EAST AND TAPPERING THE SNOWS ACROSS MISSOURI AND WORKING INTO WESTERN ILLINOIS. STILL SOME DECENT LIQUID PRECIP S INDIANA THAT WILL GRADUALLY CHANGE TO SNOW OR END ACROSS SW AND S CENTRAL INDIANA AND INCRG LIQUID PRECIP FOR SW OHIO AND THE CINCINNATI AREA AND C KY WHERE ISOLATED MAX 3 HR AMOUNTS COULD REACH 0.5"-0.8"...AT LEAST JUST NORTH OF THE OHIO RIVER. BACK EDGE SNOW NORTHEAST ILLINOIS COULD CONTINUE TO CATCH LAKE ENHANCEMENT TO CONTINUE TO PRODUCE MODERATE SNOWS THERE TILL NE MO/W CENTRAL ILLINOIS SHORT WAVE GOES BY JUST AFTER 2130Z.
