I am currently out of the office this week and supposed to be on vacation, but I am still following the weather from time to time. Anyway, I do not have access to my usual "high tech" mac draw program, but I will do my best to describe what the latest ECMWF long-range model shows for the next several weeks.
Still no signs of extended heat for southern Canada or the northern U.S.
The week of Aug. 12 to 18
--Unseasonably warm from British Columbia on north through most of northern and all of NW Canada
--Slightly cooler than normal from southern Saskatchewan through southern Quebec through the northeast and Midwest U.S. and into the Middle Atlantic states.
--Dry western BC
--Somewhat wet from southern Prairies to Ohio Valley.
The week of Aug. 19 to 25
--Slightly wetter from Canadian Rockies to extreme southern Prairies/northern Plains to central Ontario.
--Dry U.S. Rockies to Texas coast.
--Unseasonably warm from Alaska through most of northern Canada then into Newfoundland.
--Slightly cooler than normal from southern Prairies to U.S. Middle Atlantic coast. Near-normal temperatures across eastern Canada.
--Below-normal temps for California.
--Very hot southern U.S. Plains.
The week of Aug. 26 to Sept. 1
--Warmer than normal from Alaska through NW Canada and also Newfoundland.
--Cooler than normal southern Prairies to Ohio Valley
--Somewhat wet from Manitoba to Midwest U.S.
--Dry pattern NW Canada
--Drier than normal U.S. Gulf region to Bahamas
The model also continues to predict below-normal tropical storm/hurricane activity in the Atlantic Basin through most of August, which is currently in line with what is going on now.
A major storm system will take shape over the southern U.S. and track up toward the Great Lakes later in the weekend bringing a wide change of precipitation types to eastern and parts of Atlantic Canada.
Several storms to talk about......
Here is our latest thinking on the clipper-type storm that will strengthen east of New England later Tuesday.
Impressive storm snowfall totals out of Atlantic Canada...
Back from sunny, warm Florida.....
Sunday night and Monday system into eastern Canada and more cold....
