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...LATEST WATER VAPOR SATELLITE LOOP INDICATING POTENT MID LEVEL LOW PRESSURE SYSTEM TAKING A MORE EWD TRACK ALONG OR JUST SLIGHTLY S OF THE KY/TN BORDER. A SUBTLE BUT RELATIVELY STRONG MID TO LOW-LVL WAVE OF ENERGY...CURRENTLY APPROACHING CENTRAL IN/WRN KY IN SATELLITE IMAGERY PROGRESSING EWD. AHEAD OF THIS FEATURE...A NEW DEFORMATION BAND APPEARS TO BE TAKING SHAPE ALIGNING ITSELF RIGHT ALONG AND JUST N OF SFC FRONTAL BOUNDARY. LATEST SFC MESOANALYSIS SHOWS TEMPS TO BE AT OR BELOW FREEZING WITH LIGHT SNOW ALREADY FALLING ACROSS MOST OF THE DISCUSSION AREA FROM E-CENTRAL IN...ACROSS CENTRAL OH...EXT NRN WV...INTO SWRN PA. IN THE PAST HR MODERATE SNOWS ARE BEING REPORTED JUST AHEAD OF THE AFOREMENTIONED WAVE ACROSS CENTRAL/ERN IN AT GUS AND MIE.

LATEST BLENDED TPW PRODUCT INDICATES THAT 0.5-0.6" PW VALUES HAVE SURGED EWD AND ARE POOLING ALONG THE W TO E SFC BOUNDARY. THIS ALSO CORRELATES WELL WITH LATEST SATELLITE DERIVED SNOWFALL RATE PRODUCT SHOWING 0.2"/HR IN-CLOUD RATES AT 1845Z. WHILE THIS AREA DOES SIT IN A RATHER BROAD AREA OF MID TO UL DIVERGENCE PER EXPERIMENTAL GOES SATELLITE WIND PRODUCT...THE LACK OF STRONG UL JET ENERGY WILL LIKELY LIMIT WIDESPREAD HVY SNOWFALL RATES.

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...MEDIUM-HIGH CONFIDENCE FACTOR IN SHORT TERM OUTLOOK...OVER THE NEXT SEVERAL HRS ANTICIPATING DEFORMATION BAND TO BECOME BETTER ORGANIZED WITH A NARROW AND ELONGATED SWATH OF LGT TO MOD SNOWS DEVELOPING. LOCATIONS JUST N OF I-70 MAY EXPERIENCE SNOWFALL RATES OF 0.2-0.4"/HR WITH POSSIBLE 0.5"/HR INTO THE EARLY EVENING HRS.
