SYNOPTIC OVERVIEW: Much like the morning, the upper ridge at 500 hPa is still affecting western Canada, a low pressure system is situated off Alaska. Atmospheric river forecasts are showing IVT values over the 250 kg m-1 s-1 threshold by June 2nd and 3rd and then again on the 5th. Upper air charts are from 1200 UTC, as 0000 UTC charts were not available.
Of interest next week, high amounts of precipitation are expected on the 5th according to the GEM 2.5. This may be associated with the long range atmospheric river forecast whereby, moisture is advected over to the Rockies from the Pacific.
