The ECMWF has released their updated computer model seasonal forecast for the summer. I will issue my personal summer forecast for Canada within the next 10 days.
ECMWF model temperature departure forecast.
ECMWF model precipitation departure forecast.
Also, the new ECMWF update still indicates near neutral El Nino Southern Oscillation conditions through the summer.
The ECMWF is also predicting above normal tropical cyclone activity for the Atlantic Basin this year, especially in the Caribbean.
The ECMWF continues to forecast a very hot and dry summer from the U.S. Rockies to the southern and central Plains of the U.S.
Mild air masses likely to outnumber the chilly air masses for a good part of October.
Jet stream pattern across North America will become amplified across North America into next week, which means more extremes in weather.
Warm weather will dominate in the eastern half of the country for the next week. Pattern change possible during the last week of September.
The jet stream will strengthen from the Pacific across southern Canada over the next 1-2 weeks which will keep any sustained chilly/cold air masses up across western Alaska and eastern Siberia.
The latest clues to the long range into the month of October.
Late-season heat in the East and mountain snow in the West. Welcome to the fall season!
