.LONG TERM [SUNDAY THROUGH WEDNESDAY]

THIS PERIOD WILL SEE A DIGGING TROF INTO THE EASTERN CONUS, HOWEVER IT WILL BE PROGRESSIVE. YET THE COLDEST AIR OF THE SEASON WILL BE DELIVERED INTO OUR REGION RIGHT OUT OF CANADA. THE COLD FRONT WHICH LEADS THIS EXPRESS WILL ARRIVE SUNDAY NIGHT. GFS RAW TEMP GUIDANCE SUGGESTS MAX TEMPS IN THE 40S ON MON AND TUES. AM PREPARED TO TWEEK IT A CAT OR TWO BUT WILL LEAN IN DIRECTION OF THE RAW GUIDANCE. GFS IS AT BIT STRONG WITH THE DEPTH OF THE COLD AIR SO THIS PROMPTS ME TO TEMPER THE NUMBERS. WARM-UP BEGINS IN EARNEST ON WED.
