PREDICTION CENTRE OF ENVIRONMENT CANADA AT 7:00 AM CDT WEDNESDAY MAY

SYNOPTIC OVERVIEW...00Z UPPER AIR ANALYSIS SHOWING A BLOCKING PATTERN

ANALYSIS SHOWING A FILLING 990 MB LOW OVER THE DAKOTAS WITH A TROUGH
CONNECTING TO A 1004 MB LOW NEAR GREAT BEAR LAKE. 1025 MB HIGH OVER

DISCUSSION...

AB..RAIN WILL TAPER OFF TODAY OVER THE SOUTH WITH UP TO 15 MM
FORECAST TODAY. WEBCAM FROM THE MOUNTAIN AREA OF PINCHER CREEK SHOWS
NEAR 10 CM OF SNOW. ALONG MUCH OF THE ALBERTA BORDER TEMPERATURES ARE
NEAR ZERO WITH SNOW LIKELY. RAIN AND WIND FROM THE EVENT WILL BE
FOUND IN AN AWCN BULLETIN THIS MORNING. AFTER THE RAIN EXITS THERE IS
A CHANCE OF FOG IN SOUTHEASTERN ALBERTA TONIGHT.

SK..RAIN PRETTY MUCH DONE OVER THE CYPRESS HILLS AND WARNING HAS BEEN
ENDED. NOTE THAT THIS AREA HAS ALREADY RECEVIED MORE THAN 50 MM OVER
THE LAST COUPLE OF DAYS. REMAINDER OF THE PROVINCE WILL SEE GRADUAL
CLEARING AS THIS SYSTEM WINDS DOWN.

SLIGHT CHANCE OF NON-SEVERE THUNDERSTORMS OVER NORTHEASTERN
SASKATCHEWAN/NORTHWESTERN MANITOBA THURSDAY AFTERNOON.

MB..NIL SIG WX FOR MOST OF THE PROVINCE, EXCEPT FOR NORTHEASTERN
MANITOBA WHERE SOME FREEZING DRIZZLE IS BEING EXPERIENCED. SHOULD END
THIS MORNING IN ANY EVENT.

CENTRAL ARCTIC..LOW NEAR GREAT BEAR LAKE WILL GIVE RAIN TO THE AREA
TODAY. SKIN TEMPERATURES ARE JUST ABOVE FREEZING SO THERE IS A CHANCE
OF SOME MIXED PRECIP TYPE THIS MORNING. COLDER AIR IS EXPECTED TO
WRAP IN LATER TODAY WHICH MIGHT RESULT IN COLVILLE LAKE GETTING SOME
ACCUMULATING SNOW. ALONG THE WARM FRONT EAST OF THE LOW, FREEZING
RAIN IS LIKELY AT KUGLUKTUK THIS MORNING. THERE IS ALSO A FAIR AMOUNT
OF FOG AND STRATUS ALONG THE ARCTIC COAST.

KIVALLIQ..PRECIPITATION ASSOCIATED WITH THE LOW NEAR GREAT BEAR LAKE
WILL PUSH EASTWARD TODAY MOVING INTO THE KIVALLIQ REGION TONIGHT.
GUIDANCE STRONGLY SUGGESTING THAT PRECIPITATION AT CYBK TONIGHT WILL
BE IN LIQUID PHASE WITH TEMPERATURE HOVERING AROUND THE FREEZING
MARK. TOO TOUGH A CALL AT THIS POINT TO ISSUE ANY WARNINGS (I.E.
FREEZING RAIN) ALTHOUGH EXPERIENCE SUGGESTS THAT A FREEZING RAIN
WARNING WILL LIKELY BE REQUIRED FOR TONIGHT. WILL LEAVE THIS TO
DAYSHIFT TO EVALUATE FURTHER. FOR MUCH OF THE REMAINDER OF THE
KIVALLIQ THE PRECIPIATION TYPE SIGNAL IS EVEN LESS CONCLUSIVE, SO
WILL GO WITH LIGHT SNOW WITH A RISK OF FREEZING RAIN FOR NOW.

ALSO NOTE SLIGHT RISK OF FREEZING DRIZZLE THIS AM IN ONSHORE FLOW OFF
HUDSON BAY.

BAFFIN..NIL SIG WX.
