We have two robust fall storm systems attacking or set to attack the Lower 48. Check out these juicy 7 day totals. Especially the 12.5″ of liquid expected over S British Columbia which is sure to fall as big snows in the mountains.

What’s sure to kick start this fairly wet upcoming 7 day period is the robust system we have currently pushing NNE over the Heartland. Heavy, flooding rainfall as well as a significant severe threat comes with this storm.

Expect a surge of warmth and humidity up the EC, cool surge down the Plains on the backside and an area of severe weather in the typical warm sector. There’s a fairly large canopy of moderate to heavy rain too which may present local flooding.

Here’s the latest ECMWF surface charts.

Impressive 48 hr rain totals expected from this. Watch for flooding!

MODERATE risk of severe weather from this too.

The warm and cold lifting N & S is evident on the 24 hr 850 chart.

By 72 hrs, the system is up into the Appalachians and PA bringing a widespread rain to the OH Valley, possibly heavy up the I-95 from DC to Albany where severe weather is possible.

By 120 it’s spinning over Ontario while sunshine returns to much of the areas hit hard by severe weather and heavy rain. At this stage, the Pacific Northwest and British Columbia are getting hammered by wind, rain and snow.

We saw some decent snowfall yesterday over the Colorado High Country, expect more through the next 7-10 days.

Look for the really heavy stuff to fall on the Pacific facing BC Mountains.

3-6ft possible!
