Week Ahead: Continued Active

On the map below, I have drawn two large purple circles around the main weather stories we'll be looking at this week.

#1 - the stalled front over the Ohio River Valley in the southeast. Showers and thunderstorms are in the forecast today from St. Louis to Washington DC. This is the same upper-level storm system that sat over the central Rockies last week bringing day after day of inclement weather to places like Colorado.

The southern end of that disturbed area is a little cold front over north Texas and Louisiana. This will be the focal point for isolated severe thunderstorms later today.

#2 - a new storm system is moving on shore in the Pacific Northwest today and it will spread showers and thunderstorms with some mountain snow into Washington and Oregon, as well as the northern half of California. It will spread into the central and northern Rockies for the middle of the work week. BY Wednesday, it will spawn some severe weather in the central plains states.

Think It's Been Wet?

The map below shows the total accumulated precipitation for the last 7 days across the nation - it's been a wet one for many! With few exceptions - just about the entire lower 48 states have seen measurable precipitation.

And it has been a rather cool spring thus far for many of us. Here in Denver, we are running almost 8 degrees cooler than average so far this May! Other cooler-than-normal locations thus far in May include...

  • Phoenix, Arizona - 2 degrees cooler than average

  • Pendleton, Oregon - 3 degrees cooler than average

  • Bismarck, North Dakota - 8 degrees cooler than average

  • Grand Rapids, Michigan - 1 degree cooler than average

  • Waterloo, Iowa - 4 degrees cooler than average

  • Oklahoma City, Oklahoma - 2 degrees cooler than average

    Places from Atlanta, Georgia to Burlington, Vermont are running about 1 to 2 degrees ABOVE normal thus far this May.
