KEY MESSAGES:
- A SLOW WARMING TREND BACK INTO THE 90S COMMENCES TOMORROW.
- CHANCE (20-50%) FOR RAIN (0.01") ON SUNDAY BUT QPF TOTALS WILL
STRUGGLE TO RISE ABOVE A WETTING RAIN(0.10") FOR ANY GIVEN
LOCATION.
- VERY SLIGHT CHANCE (15-25%) OF SHOWERS OR THUNDERSTORMS TUESDAY
AFTERNOON AND EVENING.
WEATHER PATTERN OVERVIEW:
UPPER LEVEL LOW TRACKING ACROSS CANADA HAS FLATTENED THE RIDGE
WITH FLOW ALOFT TURNING SLIGHTLY TO THE SOUTHWEST TOMORROW WHICH
WILL ALLOW A WARMING TREND TO COMMENCE. A SHORTWAVE MOVING THROUGH
ON SUNDAY WILL PUT THE WARMING TREND ON A BRIEF PAUSE AND BRING A
FEW SHOWERS AND THUNDERSTORMS ACROSS THE REGION, BUT AT THIS TIME
THEY DON'T LOOK TO BE BIG RAINMAKERS.
RIDGE OF HIGH PRESSURE REBUILDS ON MONDAY BUT AGAIN MAY BE
FLATTENED BY ANOTHER SHORTWAVE MOVING THROUGH ON TUESDAY. WIDE
DIVERGENCE IN THE MODELS ON HOW MUCH THIS WAVE EFFECTS THE RIDGE
AS WELL AS ANY PRECIPITATION CHANCES IT MAY BRING. AFTER TUESDAY
THE RIDGE REALLY FLEXES ITS MUSCLES AND AND WE COULD SEE HIGHS
REACHING THE CENTURY MARK YET AGAIN STARTING THURSDAY AND LASTING
INTO THE WEEKEND.
FORECAST CONFIDENCE & DEVIATIONS:
MODERATE TO HIGH ON THE NEXT WARMING TREND INCLUDING NEXT WEEKEND.
LOW ON PRECIPITATION AMOUNTS SUNDAY, EVEN LOWER CONFIDENCE ON
PRECIPITATION CHANCES TUESDAY AFTERNOON.
