BOS to PDX - next week, mid-Feb

Hi everyone, we’re planning a cross-country move in mid-February, traveling with my partner and our two cats. Our goal is to reach Portland, OR, as quickly as reasonably possible while avoiding risky weather conditions. I know this probably gets asked a lot but am hoping to get some advice.

We’re hesitant about taking the shortest route (I-80) due to potential weather hazards. We both have experience in snowy weather driving but are generally risk-averse. Instead, we’re considering starting with a northern route (I-90) through New York, then transitioning to I-70 before the Rockies. If conditions worsen, we’d divert south to I-40. Does this general approach make sense?

We are open to tacking on an extra day or so at any leg of the trip to deal with inclement weather or because we need a break.

Here’s the planned route:

• Day 1: Boston, MA → Syracuse, NY (via I-90 W)
• Day 2: Syracuse, NY → Cleveland, OH (via I-90 W and I-80 W)
• Day 3: Cleveland, OH → St. Louis, MO (via I-70 W)
• Day 4: St. Louis, MO → Denver, CO (via I-70 W)
• Day 5: Denver, CO → Reno, NV (via I-70 W → I-80 W)
• Day 6: Reno, NV → Portland, OR (via I-80 W → I-84 W)

A lot of these locations have points where we could divert southward to possibly less risky weather pre-Rocky Mountains. Any advice or feedback on the route or other considerations we should keep in mind?

Last question, does anyone have any weather apps they recommend when traveling like this? I've been using Windy for more macro-trends and it's been helpful.

Thanks in advance!

P.s. weather is looking not the best next-week but we are taking it day-by-day.
