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...WV IMAGERY DECPICTS SVRL FEATURES OF INTEREST ACROSS THE MID-ATLANTIC REGION...POSITIVELY TILTED MID-UPPER LVL TROF AXIS EXTENDING SW FROM S CENTRAL NY TO THE GULF COAST...MID-LVL VORT ROTATING ENEWD FROM THE KY/TN BORDER TWDS FAR SW VA..AND AN THE OLD DEFORMATION ZONE N OF THIS VORT FROM SW OH STRETCHING ACROSS PA TO N NJ/SE NY. WHILE THE DEFOMATION ZONE PRECIP HAS BEEN DECAYING OVER THE PAST FEW HRS..A LOBE OF STRONGER ENERGY HAS BEEN ROTATING NWD TO THE NE OF THE VORT ENTERING SW VA. THIS HAS INCRSD PRECIPITATION ACROSS S/CENTRAL WV AND VA OVER THE LAST FEW HRS AND IS BEGINNING TO SHAPE/FOCUS A NEW DEFORMATION ZONE FROM CENTRAL WV TO CENTRAL PA. RECENT EXPERIMENTAL NESDIS SNOWFALL RATE PRODUCT (AVAILABLE AT CICS.UMD.EDU/SFR/ OR THROUGH NASA SPORT'S WEBSITE) FROM 07Z INDICATED LIQUID EQUIVALENT MAX AREAL AVG IN CLOUD RATES OF ROUGHLY 0.02-0.03"/HR OR 0.2-0.3"/HR SFR'S ACROSS SW TO CENTRAL PA ASSCD WITH THE OLD DEFORMATION BAND AND SIMILAR RATES..THOUGH MUCH MORE LOCALIZED OVER HIGHER ELEVATIONS OF ERN WV ASSCD WITH THE S/WV ENERGY LIFTING N.

SHORT TERM OUTLOOK VALID 0930-1230Z...MEDIUM CONFIDENCE FACTOR IN SHORT TERM OUTLOOK...IR CLOUD TOPS HAVE STARTED TO SHOW A SLIGHT COOLING TREND OVER THE PAST 1-2 HRS OVER N WV/W MD/SW PA AS LIFT FROM THE S/WV ENERGY STARTS TO ENHANCE PRECIP. HOWEVER..WITH FRONTAL BNDRY DRAPED E-W ACROSS THE REGION AND ALMOST NO BELOW FRZG SFC TEMPS S OF THE MASON DIXON LINE..THE BETTER CHC FOR MOD SNOWS APPEARS TO BE OVER SW-S CENTRAL/CENTRAL PA AS THE S/WV LIFT ROTATES NWD OVER THE NEXT FEW HRS WITH SFR'S OF ABOUT 0.5"/HR POSSIBLE. WITH THE COLDER AIR BEHIND THE MID-UPPER LVL TROF AXIS SLOWLY PRESSING E ACROSS SW PA/NRN WV/W MD AND TD'S NR FRZG..THE DVLPG PRECIP MAY BE HVY ENOUGH TO FORCE P-TYPE TO BE SNOW ACROSS THESE AREAS FOR A BRIEF PERIOD BEFORE WAA/SRLY FLOW IMPINGES NWD CAUSING MIXING OF PTYPES.
