SPECIAL MESSAGE:

This NOAA site will no longer provide GOES-East imagery. For access to high resolution GOES-East imagery from GOES-16, please go to the site: https://www.star.nesdis.noaa.gov/GOES/index.php. We apologize for the inconvenience and appreciate your patience.

USER MESSAGE:  

Effective 1200 UTC November 16, 2015, the NESDIS Satellite Analysis Branch (SAB) Satellite Precipitation Guidance Message Product (SPENES) will no longer be issued for the continental US (lower 48 states). SAB will continue satellite support to WPC and satellite-based information from SAB may be integrated by WPC's forecasters into their MPDs (Mesoscale Precipitation Discussions). This is intended to provide a single source of centralized guidance on heavy rainfall and flash flood threats and ensure consistent message delivery. More information about the MPD is available at: http://www.wpc.ncep.noaa.gov/metwatch/metwatch_mpd.php

SATELLITE ANALYSIS AND TRENDS...MAIN UPPER LEVEL SEMI-CIRCULATION CENTER AS PER LATEST GOES WATER VAPOR AND SATELLITE WINDS WAS CONTINUE TO DIG SOUTH TOWARD THE IA-MO BORDER IN RESPONSE TO GIANT BROAD FLAT RIDGE ACROSS BRITISH COLUMBIA. IMPORTANT FEATURES FOR SNOW WAS DEFORMATION SLOWLY DRIFTING SOUTH OR RE-EVOLVING FURTHER SOUTH ACROSS E CENTRAL/SE IOWA INTO NW ILLINOIS AND EXPANDING EAST AND SE. WHAT THIS DIGGING AND DEEPENING TROUGH WAS DOING WAS TAPPING MAX PRECIPITABLE WATER MOISTURE CENTERED SOUTHERN MISSOURI AND ILLINOIS AND CONVEYOR BELTING IT INTO THE DEFORMATION FOR MAX SNOW PRODUCTION EFFICIENCY WITH CURRENT BORDERLINE SURFACE TEMPS AND ALOFT TO 850MB. SO THERE IS A CONSTANT BATTLING OUT BETWEEN THE DEEP MOISTURE BEING THROWN INTO THE COLDER AIR OF THE DEFORMATION AT THE SAME TIME DRIER AIR FROM MINNESOTA...WISCONSIN AND TO A LESSER EXTENT NW IOWA SETTLE SOUTH AND SE.
.
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 1530-1830Z...MEDIUM CONFIDENCE FACTOR IN SHORT TERM OUTLOOK...SNOW WILL CONTINUE TO EVOLVE WITH BEST DEFORMATION AND INTO ENOUGH COLD AIR AND FORCED MOISTURE TRANSPORT. BELIEVE STEADIEST AND HEAVIEST SNOW WILL SHIFT ESE AND SE FROM CURRENT E CENTRAL TO INTERIOR SE IOWA AND NW ILLINOIS. BUT IT WILL ALSO BE AN INCREASING CLASH OF COLDER AND DRIER AIR NORTH WITH WARMER AND MORE MOIST AIR TO THE SE WHICH WILL MAKE IT DIFFICULT TO JUDGE TIMING OF RAIN CHANGE OVER TO SNOW AND EXACT AREA OF HEAVIEST ACCUMULATING SNOW THIS PERIOD. SEE GRAPHIC THAT WILL BE SENT TO HOME PAGE SHORTLY. SEE LATEST WPC SNOW DISCUSSION AND GRAPHIC FOR ADDITIONAL DETAILS.
