Weekly Long-Range Model Forecast Interpretation

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.
