Looking at Snow Water Equivalent data for Montana today (image above), you’d have to say that Montana is looking pretty good for this time of year, particularly southern/southwestern Montana, while the Clark Fork and Bitterroot drainages are running close to normal.
Impressively, from the image below of month to date precip compared to normal, so far in March the Pacific NW, Montana, Idaho, and Wyoming are running below average, though Utah, Colorado, and even New Mexico have been getting pounded.
What’s happening with the northern tier, at least in terms of precipitation, certainly seems to fit the traditional ENSO modeling (El Nino currently) – see the latest ENSO Diagnostic Discussion report.
