Hey everyone, I haven’t posted an update for North America for about a month and a half, so now is the time for a check on the long term outlook. This outlook has been quite complex, so please enjoy!
4-5 March GFS is forecasting light-moderate snow for the BC coast and Rockies. EPS Control shows more extensive snowfall with heavy snowfall along the BC/PNW Coast and light-moderate falls for most of the Rockies. No falls for the Sierra Nevada on most charts.
6-8 March GFS is forecasting light-moderate snow for BC/PNW and the Montana and Idaho Rockies. EC Monthly Control is forecasting moderate-heavy precipitation from Southern California, all the way up the coast to BC. EC predicts lighter snowfall in the BC/Wyoming/Idaho/Montana/Utah Rockies.
9-11 March EC Monthly Control is forecasting heavy snow for the BC Coast/PNW and moderate snow for the BC Rockies. The low moves southwest and light-moderate snow falls from Montana, all the way down to Arizona. No snowfalls for California according to current charts, except CFS. CFS likes heavy falls in the PNW, moderate falls in the BC and Sierra Nevada and light falls to the Rockies. On the 11th and 12th, heavy precipitation falls on the West Coast, possibly creating a dump for the coastal hills.
12-14 March EC Monthly Control forecasts heavy snow in the Sierra Nevada, PNW and the BC Coast, associated with a cold core low. Lighter snow is forecast for Utah, Arizona and Idaho. CFS shows heavy falls on the West Coast on the 12th and moderate snowfall in the Rockies on the 13th.
14-16 March EC Monthly Control is forecasting heavy snow hitting the BC Coast, with lighter snowfall in the BC Rockies and PNW with heavy snow in the Sierra Nevada and moderate snow in Utah, Colorado, Idaho, New Mexico and Wyoming. CFS doesn’t show moisture until the 16th.
16-17 March EC Monthly Control is forecasting snow for BC/PNW in this period with a cold core low coming over BC and dying out over Montana and Idaho with lighter showers there. CFS shows moderate-heavy snowfall in the PNW/BC/Montana and Idaho Rockies. On the 18th, there is the possibility of heavy falls in the Tahoe region.
As usual, I let my audience decide the accuracy of these forecasts. I don’t proclaim a high level of accuracy, but it is quite interesting to watch the long range forecasts. Thank you for reading.
