Expect typically stormy mid-spring weather to be at hand through Friday. A deep upper low positioned over the Pacific north-west will guide several smaller upper troughs (dashed lines) over the western United States.
Each trough lifts the atmosphere; with plentiful surface moisture this week, the lifting should be sufficient to break the “cap” and trigger thunderstorm development. Two surface cold fronts will also be in the region this week, with the stronger front due Friday. These fronts will further aid lifting and provide focal points for storm formation.
With all of this going on, there is a daily chance of thunderstorms in my forecast until the weekend. As always, there is some potential for a few severe storms to form, although the overall pattern points to just a "slight risk" in the days to come.
