KEY MESSAGE 2
LOW PREDICTABILITY WITH A GOOD DEGREE OF DISAGREEMENT IN 500 MB
MASS FIELD FORECAST OUTPUT BETWEEN THE GLOBAL NWP AND AI
GUIDANCE FOR THE LATE WEEK AND EARLY NEXT WEEK TIME FRAME.
FIRST, UNCERTAINTY SURROUNDS HOW FAR NORTH A FRONTAL BOUNDARY
GETS DURING FRIDAY. THIS IS IMPORTANT AS THIS WILL DETERMINE
PRECIP TYPE(S), ESPECIALLY FURTHER NORTH WHERE TEMPERATURES WILL
BE CLOSER TO FREEZING. OTHERWISE SOUTHERN PORTIONS OF THE
REGION SHOULD SEE PRIMARILY RAIN ON FRIDAY, BUT COLDER AIR MAY
GET INTO TOWARDS EARLY SATURDAY WHERE SOME OF THE PRECIP MAY BE
IN FROZEN FORM BEFORE EXITING AND PUSHING TO THE EAST.
SECOND, SOME GUIDANCE IS SUGGESTING ANOTHER WAVE OF LOW
PRESSURE ALONG OR JUST OFF THE COAST TOWARDS LATER IN THE
WEEKEND. SOME OF THE ECMWF AI AND NOW THE ICON DETERMINISTIC
RUNS INDICATING ANOTHER WAVE OF LOW PRESSURE AND POTENTIAL EAST
COAST STORM LATE SUN INTO MON. FOR NOW WILL CARRY STRAIGHT BLEND
/ CONSENSUS GUIDANCE UNTIL DETAILS COME BETTER INTO FOCUS.
SUFFICE IT TO SAY THERE WILL BE CHANCE OF SNOW OR MIXED PRECIP
LATE IN THE WEEKEND AND POTENTIALLY EARLY NEXT WEEK ON MONDAY.
