SYNOPSIS: A TROUGH OF LOW PRESSURE WILL APPROACH TODAY, CROSSING THE REGION
SLOWLY ON MONDAY. RAIN OR DRIZZLE WILL BEGIN LATE TONIGHT AND BECOME HEAVY AT
TIMES OVER THE MIDDLE AND LOWER BASIN ON MONDAY. THE RAIN WILL BE ACCOMPANIED
BY WELL ABOVE SEASONAL TEMPERATURES AND COULD LEAD TO RAPID SNOW MELT. ON MONDAY
EVENING, COLD AIR MOVING IN FROM THE NORTH COULD LEAD TO A CHANGEOVER TO SNOW
WITH A RISK OF FREEZING RAIN FOR THE UPPER BASIN. THIS CHANGEOVER MAY OCCUR
OVER THE MIDDLE BASIN AS PRECIPITATION WINDS DOWN TUESDAY MORNING.
AT THIS TIME, THE FOREIGN GUIDANCE IS FAVOURED. CANADIAN FORECAST GUIDANCE IS
SLOWER TO END THE RAIN OVER THE LOWER BASIN, AND IS SHOWING A PROLONGED PERIOD
OF FREEZING RAIN SETTING UP OVER THE MOUTH OF THE RIVER AND STRETCHING TOWARDS
THE GULF OF ST. LAWRENCE. FOREIGN GUIDANCE IS PREDICTING A SMALLER AREA OF
FREEZING RAIN WELL TO THE EAST OF THE BASIN ON TUESDAY NIGHT.
