DTN Ag Weather Brief

METEOROLOGICAL DISCUSSION

The northern branch of the jet stream features a ridge over Alaska and western Canada. The polar vortex over central and eastern Canada and some ridging over Greenland. This is producing cold/very cold temperatures over most of Canada. The southern branch of the jet features a ridge off the west coast of the U.S. and a low amplitude jet with embedded disturbances across the U.S.

EXTENDED OUTLOOK

The U.S. and European models are in fair agreement during the next 10 days. The northern branch of the jet stream will feature a ridge over Alaska and far western Canada. The polar vortex over central and eastern Canada and some weak ridging over Greenland. This will be a cold pattern for much of Canada except the far west. The southern branch of the jet will feature a strong ridge over the western U.S. A trough over the central and eastern U.S. and a ridge in the western atlantic. This will be a colder weather pattern for the central U.S. as the cold air in Canada moves southward into the southern branch trough. It will also be a stormy pattern over the south-central and eastern U.S. with gulf moisture flowing into the trough.

This pattern will feature variable temperatures in the Midwest during the next 5 days, below normal days 6-10. Precipitation near to below normal northwest, near to above normal south and east. The northern plains will see variable temperatures. Precipitation below normal. The southern plains will see variable temperatures. Precipitation near to below normal. The Delta states will see variable temperatures. Precipitation near to above normal.
