   AREAS AFFECTED...MAINE
   
   CONCERNING...HEAVY SNOW 
   
   VALID 192244Z - 200245Z
   
   SUMMARY...ONGOING SNOWFALL IS EXPECTED TO CONTINUE WITH
   INTENSIFICATION LIKELY AS THE SURFACE LOW APPROACHES THE AREA. AS A
   RESULT...A LARGE AREA OF HEAVY SNOW WITH SNOWFALL RATES NEAR 2
   INCHES PER HOUR IS ANTICIPATED THIS EVENING.
   
   DISCUSSION...RADAR IMAGERY AND SURFACE OBSERVATIONS REVEAL A BAND OF
   HEAVY SNOW FROM PISCATAQUIS COUNTY SWD THROUGH CUMBERLAND COUNTY.
   HEAVY SNOW HAS BEEN NOTED WITHIN THIS BAND FOR THE PAST SEVERAL
   HOURS BUT THE BAND HAS BEEN FAIRLY TRANSIENT...PROGRESSING NEWD AT
   AROUND 40 KTS. HOWEVER...THE NRN PORTION OF THIS BAND...PRIMARILY
   OVER PISCATAQUIS AND SOMERSET COUNTIES...HAS RECENTLY SHOWN LESS
   PROGRESSION AND SOME ADDITIONAL DEVELOPMENT HAS BEEN NOTED W OF THE
   PRIMARY BAND.
   
   ADDITIONALLY...MOST MODEL GUIDANCE INDICATES THAT FRONTOGENESIS/WAA
   WILL STRENGTHEN AS THE SURFACE LOW...CURRENTLY CENTERED JUST E OF
   CAPE COD... DEEPENS AS IT MOVES NEWD. AS SUCH...INTENSIFICATION OF
   THE ONGOING SNOW WILL FAVOR THE DEVELOPMENT OF WIDESPREAD HEAVY SNOW
   WITH SNOWFALL RATES FROM 1 TO 2 INCHES PER HOUR...PARTICULARLY
   ACROSS CNTRL ME.
