We’ve got quite an interesting weather pattern right now, but at the same time it’s a frustrating one, especially for areas that need rain, like Duluth (-4.02″ below normal precipitation since January 1st)
I’ll try to break down what’s going on now and what may happen over the next few days.
1: A strong upper level trough across the western U.S., this trough will be moving ENE through Wednesday. Rounds of showers and thunderstorms with heavy rain and possible severe weather will occur tonight NW of an upper level ridge (pink outlined area on map)
2: More showers and thunderstorms will occur Monday and Monday night from southwest to north-central Minnesota, but probably staying W-NW of Duluth.
3: Tropical Storm Cristobal moving across Louisiana through Monday afternoon. After that it looks like the remnants of Cristobal will track N-NE, possibly passing over eastern Wisconsin and eastern Lake Superior on Wednesday! There will be a heavy rain threat associated with Cristobal, but most of this may end up staying east of the Northland.
4: So where does this leave us for rain prospects in Duluth this week? I’d say the chances for a much needed soaking rain in Duluth are diminishing. The threat for heaviest rain appears greatest NW and E of Duluth through midweek, but this doesn’t mean we won’t get any rain in Duluth this week, but the chances for a heavy soaking rain look less likely than they did a few days ago. Our best chance for some more rain in Duluth looks to come in the Tuesday and or Wednesday time frame.
Notice how the thunderstorms over the Dakotas and far northwest Minnesota are moving more SW to NE while not really pushing to the east this evening as the ridge is holding tight as storms ride W-NW of said ridge.
